How Much Does it Cost To Repair a Roof Leak?

A leaky roof can cause a multitude of problems, and roof repairs aren’t often wallet friendly. No two roof problems are the same — some are minor, while others are severe and may even require a full roofing material replacement. It’s important to address repairs as soon as they are spotted, since the cost to repair a roof leak could be far less than the cost to address severe water damage to the inside of the home.

The longer a roof is allowed to leak, the greater the problems those leaks will cause. Jumping on the problem early can prevent thousands of dollars of damage to interior insulation and sheetrock, as well as reduce the potential for mold to breed and grow.

Modernize created this guide to roof repair costs to help homeowners gain a better understanding of the potential costs associated with repairing a roof leak. Because your roof plays such an important role in keeping the inside of your house dry it’s almost always recommended to hire a professional roofing contractor to address roofing repairs regardless of whether they are minor or severe.

How Much Does a Roof Leak Repair Cost?

Providing exact cost estimates for roof leak repair costs is difficult because the problem causing the leak could range from trivial to severe and involve an equally wide range of issues. For instance, a few wind- or age-damaged composition shingles could lead to water penetration, as could a piece of worn-out flashing. Here are some estimates for the cost to repair roof leak:

Minor Leak Repair Costs

$150–$1,500

Minor roof leak repair issues include damaged tiles, slates, or shingles; deteriorated or damaged flashing, punctures, or nail holes; and standing water.

Major Leak and Damage Repair Costs

$1,500–$8,000

Major roofing repairs are not wallet friendly, but they are extremely important. Major roofing problems could include water rot to sheathing and trusses/rafters, large sections of damaged roofing materials such as wind-damaged asphalt or composition shingles, sagging of the entire roofline, and improperly or damaged flashing that requires complete replacement.

Cost Comparisons: Roof Types and Materials

The cost to repair roof leak varies depending on the type of roofing material. Here are some baseline numbers for roof leak repair costs for different roofing materials.

• Tile roofs are extremely durable and rarely have issues, but when they do, it can be expensive. Average repair costs range from $1,300–$1,400.
• Slate is another extremely rugged roofing material, but it’s also hard to work with due to its weight. Average repair costs range from $1,500–$1,600.
• Asphalt shingles are a popular roofing material and easy to install and fix, though they lack the longevity of other roofing products. Average repair costs are about $800.
• Composite shingles include fiberglass to reinforce strength and increase durability. Average repair costs are around $900.
• Aluminum and steel are the most common types of metal roofing material. Average repair costs are about $1,550.
• Wood shakes can add a rustic look to many styles of residential architecture, but they are prone to sun damage and are a fire hazard. Average repair costs are about $700.

These estimates may vary greatly depending on a range of factors. A handful of issues that can affect the total cost of a roof repair include severity of the problem, type of roofing material, design, and complexity of the roof, contractor labor rates and time, and cost of materials necessary to fix the problem.

Roof Leak Materials Repair Costs

The type of roofing material on your home will greatly impact the total cost of a roof repair job. Costs for roofing replacement materials are as follows, though they could change depending on where they are purchased, contractor markup, and related factors. All costs show are per square foot of material:

• Asphalt shingles: $4–$8
• Wood shakes: $8–$14
• Composition shingles: $5–$9
• Metal roofing: $10–$14
• Clay tiles: $12–$25
• Slate: $12–$22
• Flat roof: $6–$8

Additional materials costs could include new metal flashing ($15–$25 per linear foot) and underlayment ($.20–$2 per square foot depending on material choice).

Licensed roofing contractors often bid larger jobs for a set price, while they charge by the hour for minor roof repair work. Homeowners can expect to pay between $35 and $90 per hour for contractor labor. The time required to complete the work can vary depending on the nature of the roof leak and any complications that add time and complexity to the job.

Major roofing issues, such as mold remediation or structural repairs to replace or shore up water-damaged rafters, sheathing, and fascia will easily add several thousand dollars to any roofing repair costs. Discussing these issues with a licensed roofing contractor can help narrow down the total cost to repair a roof for your home.

Factors Affecting Roof Leak Repair Costs

Materials and labor aren’t the only things that can impact the cost of a roof repair. Here are some additional considerations your roofing contractor will have to deal with in order to return your roof to water-tight status.

Severity and Location of the Leak

The severity of the problem is a primary factor in total costs — larger leak issues require much more time and materials than simple issues. The location of the leak can also impact work. It’s much easier to work on a single-level home than a two-story residence.

Roof Design and Pitch

There’s not much difficulty performing roofing repairs on a simple A-frame roof with an easily walkable 5/12 pitch (5” of rise for every 12” of run). Complex and intricate roof lines are likely to increase the difficulty of repair work, as can any roof over an 8/12 pitch since anything above that degree of steepness isn’t walkable and requires special safety gear to navigate.

Home Location and Regional Labor Rates

Contractor labor rates vary by geographical location since different parts of the county have higher costs of living than others. For instance, the cost of living in Los Angeles is 51% higher than the national average, while the cost of living in Bowling Green, KY is 13% lower than the national average. Roofing contractors are likely to have higher prices depending on where they are located in order to offset higher costs of housing, goods, materials, and services.

Your home’s proximity to roofing contractors also can affect pricing. Homes that are a few miles from the contractor’s shop may see more favorable cost estimates than homes that are 40–50 miles away.

5 Tips for Choosing a Roofing Professional

Your satisfaction with your roof repair leak job will likely come down to cost, timeliness of repair work, and professionalism of your roofing contractor. Follow these tips to help select the right roofing professional for your home’s repair needs:

1. Ask friends and family for referrals. Chances are, someone you know has had a similar problem with their roof. Personal referrals from trusted sources are an excellent way to build a valued home repair team.
2. Look over online review sites. You can gain a wealth of information by reading customer reviews; however, keep in mind that a few negative reviews don’t necessarily paint a clear picture of a contractor’s work and abilities. There could be countless satisfied customers that didn’t take the time to write a review.
3. Find roofing contractors close to your home. Roofing professionals who live and work in the same community may be more likely to provide exceptional customer service, first-rate work, and return if there’s ever an issue. Local roofing professionals also will know all regional building codes and standards to ensure your repair work is completed according to local building codes.
4. Make sure they are licensed and insured. Hiring only licensed roofing professionals is your only defense in the event of substandard work because you can seek recourse from the local contractor’s board. Licensed contractors may charge more than handymen, but that extra cost comes with the assurance that you have options if the contractor abandons work or doesn’t properly address the issue.
5. Compare estimates. This tried-and-true method may lead to lower pricing, but lower pricing may not always be your best option. Make sure you understand the entire bid, from inspection to repair to removal of old roofing materials. There shouldn’t be any hidden fees in the bid, like replacement of underlayment or sheathing since these issues should be spotted during the inspection. Walk through each line of a bid to determine which roofing professional is giving you the best repair solution for the best price.

Putting it All Together

The cost to repair a roof leak depends on many variables, including type of roofing material, severity of the problem, labor, location, cost of replacement materials, and complexity of your home’s roof.

Roof leaks also can stem from a range of different issues, such as damaged tiles or shingles, missing flashing, and pooling water. The first step in solving your home’s roof leak is to find a trusted roofing professional to perform an inspection and provide an estimate. It’s extremely important to address roof leaks as soon as they appear, since delays could lead to even more repair work.
