Roof Leak Repair Cost

Roof leak repair costs $150 to $500 for minor sealing or $500 to $1,200 on average to fix the leak, replace shingles, and seal. Extensive roof leaks with structural damages cost $1,200 to $3,000 to fix and include repairing water-damaged rafters and roofing.

Roof Leak Repair Cost

Leak Size	Average Cost	Repairs
Small	$150 – $500	Sealant applied to small cracks or loose roofing No water-damaged roofing Minor repairs in one roofer trip
Average	$500 – $1,200	Multiple leaks Shingle replacements and sealing Multiple roofer visits
Large	$1,200 – $3,000	Multiple leaks with extensive damage Includes repairing water-damaged rafters and roofing Multiple roofer visits

*Repairing older roofs costs more and requires replacing larger sections.

Multiple roofer visits increase costs and may be necessary when leaks are coming from multiple locations that each need proper sealing. Roof leaks also may be from heavy condensation coming from water heater pipes or air conditioner ductwork. Leaks that go unrepaired eventually cause structural issues.

Roof Structure & Water Damage Repair Cost

Roof structure repair costs $500 to $3,000, depending on the severity. Repairing roof structure and water damage may require fixing trusses and replacing decking, underlayment, insulation, and shingles. A roof replacement is the best option if more than 25% of the roof is damaged.

Roof Structure & Water Damage Repair Cost

Repair	Average Cost
Fix Broken Truss	$500 – $1,000
Replace Roof Decking (Per 100 SF)	$300 – $600
Roof Underlayment (Per 100 SF)	$50 – $200
Replacing Wet Insulation (Per 100 SF)	$200 – $300

Internal Ceiling Leak Repair	$400 – $1,500
Replace Rafters, Collar Ties, Decking, and Roofing	$7,000 – $10,000

*Asphalt shingle replacement adds $350 to $1,000 per 100 square feet when repairs require removal and replacement of roofing to access deeper layers.

• Structural issues occur from severe water damage, improper construction, extreme weather, termites, or aging.
• Ceiling leak repair costs $400 to $1,500 to fix water damage from the roof internally.

Roof Shingle Repair Cost

Roof shingle repair costs $200 to $600 on average for replacing a few missing or broken asphalt shingles, or roofing over up to 100 SF. Fixing roof shingles costs $350 to $1,000 per square (100 SF) for a full tear-off and replacement.

Roof Shingle Repair Cost

Repair	Average Cost
Broken or Missing (3 to 25 Shingles)	$100 – $300
Roof-Over (Per 100 SF)	$300 – $600
Full Tear-off and Re-Shingle (Per 100 SF)	$350 – $1,000

*A minimum call-out fee of $150 to $300 applies for most repairs.

Roof Flashing Repair Cost

Roof flashing repair costs $200 to $500 on average for skylights, chimneys, and vents. Completely replacing the flashing costs $400 to $1,000, which includes resealing and replacing the surrounding shingles. Flashing is often metal and repels water away from roof joints and fixtures.

Roof Flashing Repair Cost

Type	Average Cost
Skylight	$150 – $500
Chimney	$200 – $500
Roof Vent Pipe	$200 – $500
Roof Valley	$200 – $850
Drip Edges	$325 – $1,200

• Skylight – Skylight flashing repair costs $150 to $500, while replacing the whole skylight unit is $800 to $1,500.
• Chimney – Chimney repair costs $200 to $500 to repair flashing, while replacing flashing costs $300 to $1,500, depending on the chimney size and type.
• Vent Pipe – Roof vent pipe flashing repairs cost $200 to $500, including re-sealing pipe caps. Pipe flashing prevents leaks at the joint where the pipe meets the roofing surface.
• Drip Edge – Replacing drip edge flashing costs $1 to $2 per linear foot. The drip edge prevents water from going underneath the shingles at the roof's edge and rotting the fascia, soffit, or roof decking.

Roof Vent Repair Cost

A roof vent boot repair costs $75 to $150 on a standard slope roof. A complete roof vent replacement costs $150 to $750 or between $2 and $15 per linear foot, depending on the size, type (eave, ridge, penetration, fan), and if it's exposed or covered by shingles.

Roof Vent Repair Cost

Type	Average Cost
Vent Boot Repair	$75 – $150
Vent Replacement	$150 – $750
Vent Pipe Flashing	$200 – $500+

*A minimum call-out fee of $150 to $300 applies for most repairs. Extra costs may apply for replacing damaged shingles around the vent.

A detachable plastic, metal, or rubber vent boot seals the vent pipe to prevent a leaking roof, water stains, moisture damage.

Roof Valley Replacement Cost

Roof valley replacement costs $200 to $850, depending on the length, slope of the roof, type (open or closed), and the number of shingles replaced. Repairing roof valleys requires removing nearby shingles, replacing flashing, install new shingles, and re-sealing.

Roof Valley Replacement Cost

Type	Average Cost
Closed Valley With Asphalt Shingles	$200 – $600
Open Valley With Metal Flashing	$200 – $850

*Costs based on an average 10 to 12 square foot valley. Prices increase for more expensive roofing materials or two layers of underlayment.

• Roof valleys are angled intersections that channel water down to the gutters, which are prone to leaks.
• Closed valleys have a continuous layer of shingles with an ice and water shield lining below.
• Open valleys have a stronger, metal strip lining that requires additional sealant.

Roof Felt Repair Cost

Roof felt repair costs $300 to $1,400 for replacing up to 100 SF of underlayment, including new flashing and removing and reinstalling roofing. Repairing the felt only costs $50 to $200 per 100 square feet for materials and labor, plus removing the old roofing to access the underlayment.

Roof Felt Repair Cost

Material	Average Cost Per Square (100 SF)
Asphalt	$300 – $1,200
Tiles	$650 – $1,400

*Includes removing the old roofing and felt, installing one layer of underlayment, and installing new asphalt shingles or reinstalling the same tiles.

• Costs depend on the roof size, type, design, and underlayment material.
• Underlayment is a water-resistant barrier that protects the roof when tiles or shingles blow off. Roofing felt lasts 15 to 30 years, and leaks occur when worn out.
• Beware of contractors who say underlayment is unnecessary. The National Roofing Contractors Association (NRCA) recommends underlayment for all roof types.

Sagging Roof Repair Cost

Sagging roof repair costs $800 to $2,500 on average to replace sections of roof decking and shingles up to 100 square feet. Fixing minor sagging roofs may only require additional support like rafter ties. Severe cases may require a full roof replacement and replacing rotted rafters.

Cost To Fix Sagging Roof

Condition	Average Cost	Includes
Minor	$250 – $800	Replacing small sections of roof decking and shingles Installing additional support like rafter ties Removing pests
Average	$800 – $2,500	Replacing sections of roof decking and shingles up to 100 square feet Installing additional support for rafters
Extensive	$3,000 – $8,000+	Replacing rotted rafters Adding a new structural ridge beam or rafter ties Installing a completely new roof

Sagging roofs are dangerous and require an inspection and design plan from a structural engineer that costs $300 to $1,000. Higher costs apply for sizing a beam replacement.

Common causes for sagging roofs:

• Excess Weight – Snow, ice, debris, or multiple layers of shingles stress the roof structure.
• Water Damage – Moisture weakens the roof and causes beams to rot.
• Pests – Termites in the roof deck, rafters, or sheathing weaken the supports.
• Old Age – Wear and tear of the roof sheathing or rafters have shifted out of place.
• Improper Installation – Wrong-sized rafters and beams or improper installation causes structural failures.
• Improper Ductwork – Contractors who remove too much of a home’s framing structure when installing ductwork can cause rafter damages and sagging.
• Structure Damage – Load-bearing walls with structural problems cause sagging in the area above the wall. Houses without significant issues that have simply settled may only need a few shingles to hide the sag.

• Metal over metal roof overlays covers the existing roof with aluminum or steel standing seam metal.
• Typical maintenance includes re-applying a corrosion-resistant coating, removing minor rust, and checking for open seams and missing or loose fasteners.

Asphalt Shingles

Repairing an asphalt shingle roof costs $200 to $600 for replacing a few missing shingles, re-sealing loose shingles, or roofing-over up to 100 SF. A full tear-off and asphalt roof replacement costs $350 to $1,000 per square (100 SF).

Asphalt Shingle Roof Repair Cost

Repair	Average Cost
Replace or Re-attach 3 to 25 Shingles	$100 – $300
Roof-Over (Per 100 SF)	$300 – $600
Full Tear-off and Re-Shingle (Per 100 SF)	$350 – $1,000

*A minimum call-out fee of $150 to $300 applies for most repairs.

• Roof-overs can only be done once, as building codes often prohibit more than two layers of shingles. More than one layer may cause rafters or trusses to break from too much weight.
• A full replacement allows for inspecting the roof deck and sheathing, and costs increase when structure repair is necessary.
• High winds can lift the deck, causing broken seals and loose fasteners.
• Shingles that are missing, brittle, buckle, curled on the edge, and shed loose granules need replacing right away to prevent leaks and water damage.
• Uncleared snow causes ice dams, wood rot, and leaks, and can block water and weaken shingles.
• Excessive temperatures, UV rays, and trapped moisture causes cracks and curls and breaks them down faster.

Composite, Laminate, and Architectural Shingles

Minor composite roofing repairs cost $200 to $300 per square (100 SF) for roof-over installations or replacing some shingles. Composite, laminated, or architectural shingle replacement costs $350 to $1,000 per square, depending on the quality of materials.

Composite Roofing Repair Cost

Type	Average Cost
Minor Repairs (Up to 100 SF)	$200 – $300
Replacement (Per 100 SF)	$350 – $1,000

• Requires replacement when the stone granules begin to come off.
• Prone to damage from high winds and can lose entire sections.
• Lightweight shingles can lift, allowing water underneath.
• Shingles are easy to replace individually.
• Composite or synthetic shingles imitate slate, asphalt, tiles, or wood, and are suitable patching materials when other roofing is unavailable.

Tile Roofs

Clay or concrete tile roof repair costs $200 to $400 for fixing a few broken or loose roof tiles. Tile roof replacement costs $400 to $1,100 per square (100 SF) for concrete or $550 to $1,500 per square for clay roofing. Extra charges apply for steep roofs.

Clay and Concrete Roof Tiles Repair

Repair	Clay Tiles	Concrete Tiles
Replacing a Few Broken or Loose Tiles	$250 – $400	$200 – $400
Replacing Up to 100 SF	$550 – $1,500	$400 – $1,100

*Steep roofs increase prices by 10% on average.

• Signs of leaks, moss growth, white stains, loose or cracked mortar, or sliding tiles indicate damage and require a roof inspection.
• Tiles break easily when walked on, by falling branches or debris, age, hail, or harsh weather.
• The underlayment lifespan tends to be less than the tiles.

Flat & Rolled Roofing - Modified Bitumen or Rubber Single-Ply Roofs

Flat roof repair costs $200 to $500 for patching minor leaks and cracks or roofing over rubber or modified bitumen up to 100 square feet. A partial flat or low-slope roof replacement costs $250 to $1,000 to remove the old materials and replace sections up to 100 square feet.

Partial Replacement (Per 100 SF) Rubber Membranes (TPO, EPDM)	$350 – $1,000

• Flashing and sealants fix minor leaks, cracks, and surface damage.
• Unclogging gutters and drains often eliminates pooling and ponding water. Increasing the slope of low spots with plaster or tapered insulation helps water flow.
• Roofing-over doesn't require removing the old roofing system, and possible application depends on the age, amount of layers, and only if there are no leaking or structural problems. Old layers severely deformed and cracked need removing before attaching new roof membranes or sealants.
• Replacement completely seals larger holes or replaces missing or storm-damaged sections.

Wood Shake or Cedar Shingles

Wood shingles and cedar shake roofs cost $250 to $500 for minor repairs up to 10 square feet and $500 to $1,500+ for repairing more significant damages up to 100 square feet. Repair costs depend on wood type, size, and installation design.

Wood Shake or Cedar Shingles Repair Cost

Repair	Average Cost
Minor Repairs Up to 10 SF	$250 – $500
Replacing Up to 100 SF	$500 – $1,500

*Thatch, serrated, Dutch weave, or pyramid shingle/shake layouts with weather-proof coatings cost an additional 16% to 45% more to repair.

Regular maintenance is necessary to prevent the wood from drying out, warping, cracking, and keeping mold, mildew, and pests away.

• Missing or broken shingles create leaks and pest problems.
• Sun exposure drys out the wood and causes UV damage.
• Improper installation, clogged gutters, and poor roof ventilation cause deterioration and wood rot.
• Attracts algae growth in humid climates.
• Cupping or curling shingles occur when exposed to excessive amounts of water.
• Moss and mildew buildup causes leaks and shingles to rot and fall off, often in shaded areas.
• Extra adhesives are required in areas with high winds.
• Fire-retardant coatings should be applied every few years to increase fire safety.

Slate Roofs

Slate roof repair costs a minimum of $500 to $750 for replacing 6 to 8 slates and basic maintenance. Replacing larger damaged areas of slate roofing costs $1,000 to $3,000 per square (100 SF).

• Prone to ice-damming.
• Edges can stick out and cause leaks when nailed too tightly.
• May require additional roof supports due to its weight.

• Roof Type, Height, & Pitch – Roofers charge more for scaffolding and labor for steep roofs with limited accessibility. Add 30% to 50% in labor costs for roofs with 4+ intersecting roof lines or roofs with a 6-12 to 8-12+ slope.
• Building Code Compliance – Roofs of old homes often don’t match the same construction standards required today. A full roof replacement may be necessary to bring an old, poorly built, or badly repaired roof up to code.
• Project Size and Complexity – Significant damages require more materials and labor. Small repairs may take one day, while large jobs, such as structural work, take several days and require more roofers and specialized machinery.
• Water Damage – Water damage may require removing mold and mildew, replacing insulation, or structural repairs. Chimneys and skylights need extra sealing and flashing work to stop leaks.
• Materials – Repair prices range drastically depending on the roofing materials used.
• Emergencies – Emergency roof repair costs $200 to $300 more, with labor rates increasing to time and a half for 24-hour service. Emergency roofers respond within a few hours after storms have settled; otherwise, appointments take 3 to 5 days to schedule.
• Season – Repairs may take more time to schedule depending on weather conditions and the contractors’ current workload.
• Debris Removal – Dumpster rental costs $220 to $780 per week to handle extensive roof repairs with debris removal.
• Solar Panel Removal – Solar panel removal for roof repair costs $400 to $1,500 and up, depending on the number of panels, roof type, size, and accessibility.
• Asbestos Removal – Older roofs may have asbestos in their insulation boards or roof shingles. Asbestos roof removal costs $20 to $75 per square foot.
• Warranty – Contractors only provide a warranty on their repairs and new parts; all previous work from other contractors will no longer have a valid warranty after altering the roof.
• Permits & Inspections – Permit and inspection prices change depending on the project's scope and the home’s location.

Roof Work Labor Cost

General roof work costs $30 to $80 per hour, plus $100 to $230 per square (100 SF) in labor and material fees. Roofers charge $150 to $300 minimum for labor on most one-story homes, depending on the job complexity.

Roof Inspection

A roof inspection costs $150 to $350 on average or up to $650 for large homes or multiple floors. Roofs should be inspected annually or after a heavy storm to find and repair minor issues before they become major problems.

Most inspections include light maintenance such as removing debris, unclogging gutters, re-attaching loose shingles, caulking and sealing, and washing off algae or moss. Ongoing maintenance is necessary to keep the roof warranties valid.

Roof Repair Permit Cost

A roof repair permit costs $70 to $250, depending on the inspection fees, location, and the project's value. Permits are needed for repairing a roof section beyond one square (100 SF) or 25% of the total roof size.

Roof Tarp Cost

An emergency roof tarp costs $200 to $1,000 on average, depending on the roof type, size of tarp needed, and roof conditions and accessibility. Most insurance policies cover the cost to tarp a roof. Some roofing companies tarp a roof for free when hiring them for permanent repairs.

Roof Tarp Cost

Frequently Asked Questions

Should I Repair or Replace My Roof?

Minor roof damages such as missing shingles, corroded flashing, or small leaks should be repaired. Roofs older than 20 years or extensive damage affecting 40% or more of the roof require a full replacement. Roof replacement costs $5,000 to $11,000 vs. most repairs at $500 to $1,500.

Roof Repair vs. Replacement

Type	Average Cost	Recommendation
Roof Repair	$500 – $1,500	Roofs less than 5 years old No extensive leaks or deck damage
Partial Roof Replacement	$2,250 – $5,000	Damage only on one side of the roof Roof has a strong structure overall Roof is around 5 years old, or repair warranty isn't longer than the expected lifespan of the roof
Overlay (Roofing Over Existing Roof)	$4,800 – $9,600	10% to 20% shorter lifespan Adds extra weight to the roof Not ideal for high-wind areas that need one layer of shingles attached directly to the deck Most building codes only allow two layers of shingles More work to remove later Harder to find leaks Can void warranty of the original roof
Full Roof Replacement	$5,000 – $11,000	Roofs older than 20 years Extensive damage > 25% of roof Shingles are curling Roof sagging or structural integrity issues Leaks, moisture, or mold on the ceiling If repairs cost more than $3,000 Allows upgrading to more weather-resistant shingles for a longer-lasting roofing solution Adds value to the home Best for roofs prone to ice dams Recover 66% if selling the home

DIY Roof Repair

DIY roof repairs are a high safety risk that may just cover up the problem or create more damage. Most roofing projects require a professional to fix and evaluate the true extent of damages. Even minor roof repairs may indicate deeper problems or improper roof installation.

Always schedule a roof inspection before or after DIY repairs to ensure no unseen damages threaten the home’s structural strength.

In-between recommended annual inspections, homeowners can perform basic roof maintenance.

• Check for loose or missing shingles, especially after a storm.
• Keep the roof clear of standing water, excessive snow, and debris.
• Trim hanging or touching tree branches.
• Check the attic and ceilings for leaking by looking for discolored spots.
• Inspect the chimney for cracks, missing mortar, or caulking.

Getting Roof Repair Estimates

Before hiring a roofing contractor, be sure to follow these tips and ask the right questions. Hiring a professional guarantees longer-lasting repairs and prevents more expensive damages in the future.

• Get three or more in-person estimates to compare and avoid scams. Beware of companies who recommend a full roof replacement when only repairs are needed.
• Ask for recommendations from family, friends, and neighbors.
• Read their reviews on HomeGuide, Google, and the Better Business Bureau (BBB).
• Select a company that's been in business for five years or more.
• Be careful with extremely low or high price quotes.
• Ask for a clear written estimate and warranty to prevent future disputes.
• Avoid large upfront payments. Instead, negotiate a payment schedule for large jobs.
• Ask about low-interest financing options they may offer.

Questions To Ask

• Are you licensed, insured, and bonded?
• How long have you been doing roof repairs?
• Are you part of professional roofing organizations like the NRCA?
• Can you provide references of past work?
• Can you provide a detailed quote of materials, labor, and costs by line item?
• Does your quote include waste disposal or taxes?
• What’s your payment schedule?
• Do you offer a warranty? What does your warranty include?
• What additional fees may be required?
• Will you obtain permits when required?
• Do you have experience claiming repairs through insurance? (if required)
• How long will the roof repair take?
• How do you handle damages on the job?
• What safety precautions do you take for the workers and residents?
• Will someone be present for the final inspections?
• Does the roof have weak spots in the plywood roof deck underneath the shingles? Patching up an area quickly without checking for damage to the roof deck first leads to worse roof damage later.
