San Rafael Roof Replacement Cost Guide (2026)

A roof replacement in San Rafael, California, typically costs between $18,000 and $45,000 for a standard single-family home with asphalt shingles (Hamilton Exteriors 2024-2026 project data). This range reflects the city's mix of hillside properties, Wildland-Urban Interface (WUI) fire zone requirements, and Marin County's higher-than-average labor and permit costs. At Hamilton Exteriors, we provide fully itemized estimates so you see exactly where every dollar goes — materials, labor, permits, and cleanup, all listed separately.

This guide breaks down San Rafael-specific pricing for asphalt, metal, and tile roofing, explains Marin County's unique code and climate factors, and walks through the permit process so you can budget with confidence.

What Does a Roof Replacement Cost in San Rafael?

For a typical San Rafael home with a 1,500 to 2,500 square foot roof, here are the 2026 price ranges by material:

• Asphalt shingles: $18,000 to $35,000
• Metal roofing: $28,000 to $55,000
• Tile roofing: $35,000 to $65,000
• Designer/luxury shingles: $30,000 to $50,000

These figures include tear-off of the existing roof, underlayment, flashing, materials, labor, and cleanup. They do not include structural repairs, decking replacement, or gutter work, which are priced separately if needed. San Rafael's pricing sits at the higher end of the Bay Area spectrum — comparable to Mill Valley and Tiburon — due to the prevalence of hillside lots, WUI fire zone mandates, and Marin County's permit and inspection requirements.

Why do San Rafael roofs cost more than the national average? Three factors dominate. First, Marin County labor rates run 15 to 25 percent above the U.S. average because contractors must earn enough to live in one of the country's most expensive regions. Second, most San Rafael neighborhoods fall within CAL FIRE's High or Very High Fire Hazard Severity Zones, which trigger Chapter 7A compliant materials — Class A fire-rated roofing, ember-resistant vents, and specific underlayment — that add $1,000 to $3,000 to a typical project (Hamilton Exteriors 2024-2026 project data). Third, San Rafael's hillside terrain and narrow streets in neighborhoods like Dominican, Gerstle Park, and the Lincoln Avenue corridor increase access costs for material delivery and debris removal.

San Rafael Roofing Costs by Material

Asphalt Shingles: $18,000 to $35,000

Architectural asphalt shingles remain the most common roofing material in San Rafael, installed on roughly 70 percent of residential roofs. Modern dimensional shingles from GAF, CertainTeed, and Owens Corning offer a 30- to 50-year lifespan and Class A fire ratings — the highest available — which is critical given Marin County's wildfire risk.

The most frequently installed products in San Rafael include:

• GAF Timberline HDZ: The most popular shingle in North America. Features a dimensional wood-shake look, Class A fire rating, and 130 mph wind warranty. Available in 20+ colors. Installed cost: $940 to $1,125 per roofing square (100 sq ft) (Hamilton Exteriors 2024-2026 project data).
• CertainTeed Landmark: A premium architectural shingle with a lifetime limited warranty. The NaturaL Shadow line provides depth and dimension that complements San Rafael's Craftsman and mid-century homes. Installed cost: $1,075 to $1,200 per square.
• Owens Corning Duration: Patented SureNail technology for enhanced wind resistance — relevant for San Rafael's exposed ridge-top properties. TruDefinition color platform delivers rich, consistent tones. Installed cost: $1,125 to $1,300 per square.

All three carry Class A fire ratings and meet California Building Code Chapter 7A requirements when paired with the manufacturer's specified fire-rated underlayment. For San Rafael homes in WUI zones — which includes most of the city's hillside neighborhoods — this combination is mandatory.

Metal Roofing: $28,000 to $55,000

Metal roofing has gained significant adoption in San Rafael over the past decade, particularly in fire-prone hillside areas like the Terra Linda and Lucas Valley neighborhoods. The primary options:

• Standing seam steel: The premium metal option with clean, contemporary lines and hidden fasteners that eliminate leak points. Popular on modern and mid-century homes throughout Marin. Installed cost: $1,400 to $1,800 per square (Hamilton Exteriors 2024-2026 project data). Lifespan: 40 to 70 years.
• Stone-coated steel: Metal panels with a stone granule coating that mimics the appearance of tile or shake. Combines metal's fire resistance with a traditional look that suits San Rafael's Mediterranean and ranch-style homes. Installed cost: $1,300 to $1,700 per square.
• Aluminum standing seam: Preferred for coastal-adjacent San Rafael properties where salt-laden marine air accelerates steel corrosion. Installed cost: $1,500 to $1,900 per square.

According to research from Oak Ridge National Laboratory, metal roofing with reflective pigmented coatings reflects up to 70 percent of solar radiant heat, reducing cooling costs by 10 to 25 percent Oak Ridge National Laboratory. For San Rafael homeowners, this translates to measurable energy savings during the warm inland summers when temperatures regularly exceed 90 degrees in neighborhoods like Terra Linda and Marinwood.

Metal is also the lightest roofing material by weight (1 to 3 pounds per square foot), making it suitable for older San Rafael homes where structural capacity may be limited. Many homes in the Gerstle Park and West End neighborhoods, built between 1920 and 1950, benefit from metal's low weight compared to tile.

Tile Roofing: $35,000 to $65,000

Tile roofs are iconic across Marin County, particularly on Mediterranean, Spanish Colonial, and Mission-style homes in San Rafael's established neighborhoods. The two primary options:

• Clay tile: The traditional choice with warm terra cotta tones that develop a natural patina over time. Extremely durable with a lifespan of 75 to 100 years. Installed cost: $1,800 to $2,500 per square (Hamilton Exteriors 2024-2026 project data).
• Concrete tile: A more affordable alternative to clay with similar aesthetics and durability. Available in flat, low-profile, and high-profile shapes. Installed cost: $1,500 to $2,000 per square. Lifespan: 50 to 75 years.

The primary consideration with tile in San Rafael is weight. A clay tile roof weighs 9 to 12 pounds per square foot, compared to 2 to 4 pounds for asphalt shingles. Many older San Rafael homes — particularly those built before 1970 in neighborhoods like Gerstle Park and the West End — may need structural reinforcement before tile installation. A structural engineer's assessment typically costs $500 to $1,500, and reinforcement work can add $3,000 to $15,000 to the project (Hamilton Exteriors 2024-2026 project data).

On the upside, tile's extraordinary lifespan means it is often the last roof a home will ever need. The cost per year of service is competitive with or better than asphalt, especially for homeowners who plan to stay in their home for 20 or more years.

Designer and Luxury Shingles: $30,000 to $50,000

Designer shingles bridge the gap between standard asphalt and premium materials like slate or cedar shake. These oversized, multi-layered shingles create dramatic shadow lines and deep texture that complement San Rafael's higher-end homes in neighborhoods like Dominican and Peacock Gap.

• GAF Grand Sequoia: A large-format shingle that mimics the look of natural wood shake. Available in Armorshield AR (Class A fire rated) and standard versions. Lifetime limited warranty. Installed cost: $1,575 to $1,800 per square (Hamilton Exteriors 2024-2026 project data).
• CertainTeed Presidential Shake: Three-laminate construction creates one of the most realistic wood shake profiles on the market. Installed cost: $1,650 to $1,800 per square.

Designer shingles offer a premium aesthetic without the maintenance demands of natural shake or the weight of tile — a practical compromise for San Rafael homeowners who want a distinctive look with lower long-term upkeep.

San Rafael Roof Replacement Cost by Roof Size

Roof size is the single largest cost driver. Roofing contractors price by the "square," which equals 100 square feet of roof area. Your roof's square footage is typically 1.2 to 1.5 times your home's footprint, depending on pitch and overhangs. Pricing reflects Hamilton Exteriors 2024-2026 project data.

These ranges assume a moderately complex roof with standard pitch (4:12 to 6:12). Steeper roofs, complex geometries with multiple valleys and dormers, and homes requiring crane access for material delivery will fall at the higher end or above these ranges.

Factors That Affect Your San Rafael Roof Replacement Cost

Two homes on the same San Rafael street can receive quotes that differ by $10,000 or more (Hamilton Exteriors 2024-2026 project data). Here are the factors that drive those differences:

Roof pitch and steepness. Steeper roofs require more safety equipment, specialized techniques, and additional labor time. Roofs with a pitch of 8:12 or greater typically cost 15 to 25 percent more than standard-pitch roofs. Many San Rafael hillside homes have steep, complex roof geometries that increase labor costs.

Number of layers to tear off. California building code allows a maximum of two roofing layers. If your home already has two layers, both must be removed before the new roof goes on. Tearing off a single layer adds $100 to $150 per square (Hamilton Exteriors 2024-2026 project data). Tearing off two layers adds $150 to $250 per square.

Roof complexity. Every valley, dormer, skylight, chimney, and pipe penetration requires additional flashing, cutting, and labor. A complex roof with 10 or more penetrations and multiple valleys will cost significantly more per square than a simple gable roof.

Accessibility. Multi-story homes, homes on steep hillside lots, and homes with limited driveway access for material delivery all increase labor costs. Crane lifts for material delivery can add $500 to $2,000 (Hamilton Exteriors 2024-2026 project data). San Rafael's hillside neighborhoods — particularly in the Dominican and Terra Linda areas — frequently require crane access or material staging on narrow streets.

Decking condition. Once the old shingles come off, damaged roof decking is sometimes discovered underneath. Replacement runs $75 to $150 per 4x8 sheet, and it is not uncommon to need 5 to 15 sheets on an older San Rafael home (Hamilton Exteriors 2024-2026 project data). A reputable contractor will include a per-sheet price in the estimate so there are no disputes on the job.

Fire zone compliance. Most San Rafael neighborhoods fall within CAL FIRE's High or Very High Fire Hazard Severity Zones. This triggers Chapter 7A requirements under California Building Code Section 705A: Class A fire-rated roofing materials, non-combustible vents and eave assemblies, and fire-rated underlayment. Fire zone compliance adds $1,000 to $3,000 to a typical project. CAL FIRE Fire Hazard Severity Zones

San Rafael Permit Requirements and Fees

Every roof replacement in San Rafael requires a building permit. The City of San Rafael Building Department processes roofing permits through its Community Development Department, and your contractor should handle the entire process — application, plan submission, and scheduling inspections.

San Rafael roofing permit fees typically range from $400 to $900, depending on the project valuation and scope (Hamilton Exteriors 2024-2026 project data). The city uses a valuation-based fee schedule, so a higher-value roof replacement (tile, metal, or large homes) will incur a higher permit fee. Permit fees appear as a separate line item in every Hamilton Exteriors estimate.

The permit process in San Rafael generally takes 1 to 3 weeks for a standard roof replacement, though complex projects or those requiring Planning Division review (historic districts, design review overlays) may take longer. Your contractor should factor this timeline into the project schedule.

For homes in WUI fire zones — which includes most of San Rafael's hillside neighborhoods — the building department will require documentation that all roofing materials meet Class A fire rating and Chapter 7A compliance. This includes manufacturer specification sheets for the roofing material, underlayment, and vent assemblies. City of San Rafael Building Department

San Rafael's Climate and How It Affects Your Roof

San Rafael's climate creates specific demands on roofing systems that differ from other Bay Area cities. Understanding these factors helps you choose materials that will last.

Inland warmth and UV exposure. San Rafael sits in a climatic transition zone. Neighborhoods closer to the bay — like Canal and Spinnaker Point — experience cooler, fog-influenced summers. Inland neighborhoods like Terra Linda, Marinwood, and Lucas Valley see warmer, drier conditions with summer temperatures regularly exceeding 90 degrees. This inland heat accelerates asphalt shingle aging through thermal cycling and UV degradation. Premium architectural shingles with enhanced UV-resistant granules perform measurably better in these conditions.

Coastal fog and moisture. Western San Rafael neighborhoods, particularly those near the San Rafael Ridge and closer to the bay, experience morning fog that burns off by midday. Persistent moisture accelerates moss and algae growth on north-facing roof planes and shaded areas under oak canopies. Algae-resistant shingles — standard on GAF Timberline HDZ and CertainTeed Landmark lines — are recommended for these exposures.

Marine air and corrosion. While San Rafael is not directly on the coast, marine air influence extends through the Golden Gate and across the bay. Salt-laden air accelerates corrosion of exposed metal flashing, fasteners, and roof penetrations. For metal roofing in San Rafael, we recommend aluminum or Galvalume-coated steel with a minimum AZ50 coating weight for corrosion resistance. Stainless steel fasteners are standard on all Hamilton Exteriors metal roof installations.

Wind exposure. San Rafael's ridge-top and hillside properties — particularly in the Dominican, Gerstle Park, and Terra Linda neighborhoods — experience higher wind loads than flatland areas. The 2022 California Building Code requires wind-resistant fastening patterns for roofs in exposed locations. GAF Timberline HDZ shingles carry a 130 mph wind warranty when installed with the manufacturer's specified fastening pattern, which exceeds San Rafael's design wind speeds.

WUI Fire Zone Requirements for San Rafael Roofs

Most of San Rafael falls within CAL FIRE's High or Very High Fire Hazard Severity Zones. This classification triggers specific roofing requirements under California Building Code Chapter 7A that affect both material selection and installation methods.

Class A fire-rated roofing. The roofing material itself must carry a Class A fire rating — the highest available. All asphalt shingles from GAF, CertainTeed, and Owens Corning carry Class A ratings. Metal roofing is inherently Class A. Clay and concrete tile are Class A. The key is that the entire assembly — not just the shingle — must meet Class A standards, which means the underlayment must also be fire-rated.

Ember-resistant vents. One of the most common entry points for wildfire embers is through attic vents. Chapter 7A requires ember-resistant vents with 1/8-inch mesh screens on all attic intake and exhaust vents. This includes soffit vents, gable vents, and ridge vents. Standard 1/4-inch mesh does not meet the requirement. CAL FIRE Ember-Resistant Vent Requirements

Non-combustible eave assemblies. Eaves and soffits must be constructed with non-combustible materials or protected with ignition-resistant materials. For roof replacements in San Rafael WUI zones, this often means replacing combustible wood soffits with fiber cement or metal alternatives, or ensuring that existing soffits are fully enclosed with ember-resistant venting.

Fire-rated underlayment. The underlayment beneath the roofing material must meet ASTM D226 or ASTM D4869 standards for fire resistance. Many standard underlayments do not meet Chapter 7A requirements, so specifying the correct underlayment is critical for WUI zone compliance.

At Hamilton Exteriors, we verify your property's fire zone designation through CAL FIRE's Fire Hazard Severity Zone map during the on-site inspection and handle all required documentation for building department approval. If your home is in a WUI zone, we specify Chapter 7A compliant materials in the estimate so there are no change orders or re-inspection fees after the project starts.

Seismic Considerations for San Rafael Roofs

The San Andreas Fault runs along the western edge of Marin County, placing San Rafael in a region of moderate seismic hazard. While roofing is not the primary structural concern during an earthquake — that belongs to the foundation and shear walls — there are roofing details that affect seismic performance.

Lightweight materials reduce seismic load. A roof's weight contributes to the overall seismic mass of the structure. Heavier roofs — particularly clay tile at 9 to 12 pounds per square foot — increase the lateral forces the structure must resist during an earthquake. For older San Rafael homes that may not have been seismically retrofitted, choosing a lighter roofing material like asphalt shingles (2 to 4 pounds per square foot) or metal (1 to 3 pounds per square foot) reduces seismic demand on the structure.

Tile attachment in seismic zones. If you choose tile roofing for a San Rafael home, the attachment method matters. The California Building Code requires specific fastening patterns for tile roofs in seismic design categories D and above, which applies to most of Marin County. This includes mechanical fastening of every tile in high-wind and high-seismic zones, rather than relying on gravity and interlocking alone. A properly fastened tile roof performs well in earthquakes, but the fastening requirements add labor cost compared to non-seismic installations.

Chimney bracing. During a roof replacement, it is worth inspecting the chimney for seismic bracing. Unreinforced masonry chimneys are a common failure point in California earthquakes. If your San Rafael home has a masonry chimney, we recommend a structural engineer evaluate it during the roofing project. Bracing or reinforcing a chimney adds $2,000 to $5,000 but prevents a hazardous collapse during a seismic event (Hamilton Exteriors 2024-2026 project data).

How Hamilton Exteriors Prices Roof Replacements in San Rafael

At Hamilton Exteriors, we approach San Rafael roofing projects differently from most contractors. Here is what sets our process apart:

Fully itemized estimates. Every estimate breaks out each cost component: tear-off and disposal, underlayment, roofing material, flashing, ridge vents, labor, permit fees, and cleanup. You see exactly where every dollar goes — no lump-sum bids that make it impossible to compare options.

Architect-led evaluation. Unlike most roofing companies, Hamilton Exteriors is led by Alex Hamilton Li, a licensed architect and general contractor (CSLB #1078806). This means we evaluate your roof as part of the whole building system — ventilation, structural capacity, energy performance, and aesthetics together. If your roof needs structural reinforcement for tile, or if a Cool Roof product would benefit your energy bills, we tell you upfront rather than after the project starts.

San Rafael-specific expertise. We have completed roofing projects throughout San Rafael — from hillside homes in Dominican to flatland ranches in Terra Linda. We know the city's permit process, the WUI zone map, and the inspectors' expectations. We handle every permit application and inspection so you do not have to navigate the building department on your own.

50-year system warranty. As a GAF Master Elite contractor — a certification held by fewer than 3 percent of roofing contractors nationwide — we can offer GAF's 50-year system warranty, covering both materials and workmanship. This is the most comprehensive warranty available in residential roofing.

Transparent per-square pricing. We quote a specific price per square for each material option, not a vague range. This makes it easy to compare materials and understand how your roof size affects the total.

How to Save on Your San Rafael Roof Replacement

Roof replacement is a significant investment, but there are legitimate ways to reduce your cost without compromising quality.

Get multiple itemized estimates. Obtain at least three estimates that break out tear-off, materials, labor, permits, and cleanup as separate line items. Lump-sum bids make it impossible to compare apples to apples and often hide markups.

Schedule in the off-season. November through February is the slower season for Bay Area roofers. While rain can cause delays, contractors often offer more competitive pricing during these months to keep crews busy. You may save 5 to 15 percent on labor.

Ask about manufacturer rebates. GAF, Owens Corning, and CertainTeed periodically run rebate programs, particularly in the spring. Your contractor should know about current promotions. Rebates typically range from $50 to $250 for qualifying installations (Hamilton Exteriors 2024-2026 project data).

Check your insurance coverage. If your roof was damaged by a covered event — storm, fallen tree, fire — your homeowner's insurance may cover part or all of the replacement. Even if you are replacing due to age, document any storm-related damage with photos before filing a claim. We work directly with most major California insurers and can document damage with drone imagery for your claim.

Consider financing. Rather than choosing cheaper materials to fit a cash budget, many San Rafael homeowners finance a higher-quality roof with low monthly payments. This often results in better long-term value because premium materials last significantly longer. Hamilton Exteriors offers $0-down financing with approved credit and extended terms up to 15 years for larger projects (Hamilton Exteriors 2024-2026 project data).

San Rafael Roof Replacement Timeline

A standard asphalt shingle roof replacement in San Rafael typically takes 3 to 5 working days from tear-off to final cleanup. Here is what the timeline looks like:

• Day 1: Tear-off of existing roofing, inspection of decking, replacement of any damaged sheathing.
• Day 2: Installation of underlayment, drip edge, and valley flashing. Begin shingle installation.
• Day 3-4: Complete shingle installation, ridge vent, and flashing around penetrations.
• Day 5: Final cleanup, magnetic sweep for nails, and city inspection.

Metal and tile roofs take longer — typically 5 to 10 working days — due to additional preparation and specialized fastening systems. Larger homes over 3,000 square feet or those with complex roof geometry may extend the timeline by 1 to 2 additional days.

The permit issuance process adds 1 to 3 weeks before work begins. We schedule all work around your availability, and your property is fully tarped and secured at the end of each workday. Every project gets a dedicated project manager who provides a specific timeline during the on-site inspection and keeps you updated daily.

San Rafael Roof Replacement vs. Other Marin County Cities

San Rafael's roofing costs sit in the middle of Marin County's range — higher than Novato but lower than Mill Valley and Tiburon. Here is how San Rafael compares to neighboring cities for a standard asphalt shingle roof on a 2,000 square foot home:. Pricing reflects Hamilton Exteriors 2024-2026 project data.

San Rafael's advantage is its relative accessibility compared to Mill Valley's narrow, winding roads and Tiburon's steep hillside estates. While WUI zone compliance is required in most San Rafael neighborhoods, the city's road network and lot configurations generally allow for easier material delivery and debris removal than Marin's more challenging hillside communities.

Hidden Costs to Watch For in San Rafael

A roof replacement can uncover issues that were not visible during the initial inspection. Reputable contractors discuss potential hidden costs upfront and provide pricing for common contingencies.

Rotten decking replacement. Once the old shingles come off, damaged roof decking is sometimes discovered underneath. Replacement runs $75 to $150 per 4x8 sheet, and it is not uncommon to need 5 to 15 sheets on an older San Rafael home (Hamilton Exteriors 2024-2026 project data). Homes built before 1980 with original plywood or skip sheathing are most likely to need decking repair.

Fascia and soffit repair. The boards along the roof edge (fascia) and underneath the eaves (soffit) are often deteriorated, especially on homes with older wood fascia exposed to San Rafael's wet winters. Repair or replacement typically runs $15 to $25 per linear foot (Hamilton Exteriors 2024-2026 project data).

Gutter replacement. If your gutters are at the end of their life, replacing them during the roof project saves the cost of a separate mobilization. Seamless aluminum gutters run $8 to $15 per linear foot installed (Hamilton Exteriors 2024-2026 project data). Many San Rafael homeowners combine gutter replacement with their roof project.

Skylight re-flashing. Skylights are a common leak point. During a roof replacement, it is recommended to at minimum re-flash all skylights ($200 to $400 each) or, if the skylights are 15 or more years old, replace them entirely ($800 to $2,500 each including installation) (Hamilton Exteriors 2024-2026 project data).

Dry rot repair. San Rafael's wet winters and older housing stock — roughly 55 percent of homes were built before 1980, according to the U.S. Census Bureau American Community Survey — mean dry rot is common in roof eaves, rafter tails, and fascia boards. Dry rot repair is priced on a time-and-materials basis and can add $500 to $3,000 depending on the extent (Hamilton Exteriors 2024-2026 project data).

Frequently Asked Questions

How much does a roof replacement cost in San Rafael?

A roof replacement in San Rafael typically costs $18,000 to $45,000 for a standard single-family home with asphalt shingles. Metal roofing runs $28,000 to $55,000, and tile roofing costs $35,000 to $65,000. These ranges include tear-off, materials, labor, and cleanup. Permit fees add $400 to $900 depending on project valuation.

Is San Rafael in a fire zone for roofing requirements?

Yes. Most San Rafael neighborhoods fall within CAL FIRE's High or Very High Fire Hazard Severity Zones. This requires Class A fire-rated roofing materials, ember-resistant vents with 1/8-inch mesh, and fire-rated underlayment that meets Chapter 7A standards under California Building Code Section 705A.

How long does a roof replacement take in San Rafael?

A standard asphalt shingle roof replacement in San Rafael takes 3 to 5 working days. Metal and tile roofs take 5 to 10 working days. The permit issuance process adds 1 to 3 weeks before work begins. Weather delays are uncommon during the dry season (April through October) but can extend timelines during winter months.

Do I need a permit for a roof replacement in San Rafael?

Yes. The City of San Rafael requires a building permit for all roof replacements. Permit fees range from $400 to $900 depending on project valuation. Your contractor should handle the permit application and all inspections. If a contractor suggests skipping the permit, consider that a red flag.

What roofing material is best for San Rafael homes?

For most San Rafael homes, premium architectural asphalt shingles deliver the best balance of cost, fire rating, and lifespan. Metal roofing is ideal for hillside WUI zone properties due to its Class A fire rating and 40- to 70-year lifespan. Tile roofing suits Mediterranean and Spanish-style homes but requires structural evaluation due to its weight.

Does a new roof increase home value in San Rafael?

According to Remodeling Magazine's annual Cost vs. Value report, a new asphalt shingle roof recoups approximately 60 to 65 percent of its cost at resale nationally. In Marin County's competitive housing market, a new roof can be even more valuable because buyers are wary of homes with aging roofs and the associated replacement costs — particularly given WUI zone compliance requirements.

Can you help with a roofing insurance claim in San Rafael?

Yes. If your roof was damaged by a storm, fallen tree, or other covered event, Hamilton Exteriors works alongside your insurance adjuster to ensure accurate damage documentation. We provide detailed, itemized repair estimates with photos that meet insurer requirements. Our project manager can be present during the adjuster's inspection to point out damage that may not be visible from the ground.

How do I know if I need a full replacement or just a repair?

Replace if your roof is over 20 years old and showing widespread issues — curling shingles, granule loss, multiple leaks. Repair if the damage is isolated to a small area and the rest of the roof is in good condition. A professional on-site inspection can clarify the right path. At Hamilton Exteriors, we recommend repair where it makes sense and will not push a full replacement if your roof has remaining life.
