A number of factors impact the final cost of a roof repair. We'll outline common causes of roof leaks, their sources, average repair costs for a 10 ft. x 10 ft. area, and more in our roof repair cost breakdown.
Common Roof Leak Causes
The average cost for a professional roof repair is $630, but it varies depending on a number of factors, including the cause of the leak, the roofing material, and more.
Know where to look when determining the cause of the leak. The main causes for roof leaks include...
Leaking gutters or leaking flashing
Corrosion of gutters and flashing can allow water to leak into the interior of the roof. These usually are well sealed but tend to erode over time.
Ice dams form when warm air from the attic melts snow close to the roof ridge and refreezes at the roof’s edge. Ice dams form a wall that doesn’t allow proper drainage, causing pooled water to damage the roof’s interior.
Leaking chimney or skylight
Leaks around chimney flashing and skylights occur due to compromised sealants, cracks, or improper installation.
High winds and severe storms can dislodge shingles leaving your roof exposed to the elements.
Valleys are small gutter sections that run down the interior angles of your roof. They become damaged by fungus, improper cleaning, and lifted shingles. Large amounts of rainwater flow through this channel, and if it’s damaged, leaks are likely to occur.
Average Cost Based on Leak Type
One of the main factors affecting roof leak repair cost is the cause and location of the leak...
|Problem||Solution||Material Cost||Professional Repair|
|Leaking gutters or flashing||Clean gutters and repair flashing||$90||$150|
|Ice dams||Rake roof, apply ice melter, or install heating cables||$50||$110|
|Leaking chimney or skylight||Replace flashing or caulk leaking areas||$25||$85|
|Missing shingles||Replace shingles||$100||$160|
|Damaged valleys||Replacing flashing and shingles||$25||$85|
The professional repair costs above reflect material costs plus one hour of average-priced labor.
If you're confident in your ability to fix the damaged area yourself, you'll only need to pay for the material costs to provide the solution. If you choose to have a professional repair the issue, you'll be paying a combined fee for both the materials and hours of labor.

Average Cost Based on Roofing Material
Leaks will appear in different areas of your roof depending on your roofing material. Start looking for leaks by entering your attic on a rainy day with a flashlight.
Keep a close eye for mold, odor, drips, sunken sections, or other forms of wood rafter deterioration. All of these symptoms can point to leaks.
The table below identifies where leaks are most likely to occur depending on the roofing material...
|Roof Material||Common Leak Location||Professional Repair|
|Asphalt||Vertical slits||$100 - $1,000|
|Composite||Shingles, joints, and trim||$110 - $1,100|
|Metal||Fasteners and seams||$300 - $1,500|
|Wood||Valleys and shingles||$500 - $700|
|Slate||Tile edges||$1,000 - $2,000|
|Tile||Underlayment and shingles||$100 - $510|
|Rubber / Foam||Cracks and the insulation board||$200 - $1,000|
The type of roofing material and location of the leak will dictate the overall price of the repair.
Roofs with asphalt shingles are the most common, and therefore the least expensive. Rarer materials like slate and metal will undoubtedly cost more for a repair.
Costs of General Labor and Repair Materials
Professional roofing contractors charge around $3 per square foot for a roof repair project, or around $60 per hour.
A general roofing contractor should be able to repair asphalt shingles, and their costs should mimic these averages. However, if your material is less common, such as slate or metal, the costs of repairs will exceed these averages, as they require a more specialized roofing contractor.
The cost of materials is usually included in the final quote for the project, but some contractors charge them separately.
