How Much Does a Roof Repair Cost?


Your roof protects your home from the elements, keeping out the rain, wind, sun, and snow. Over time, however, things can occur that may cause your roof to begin letting in moisture and causing leaks. When dealt with quickly, these roof repairs generally cost a lot less than a full roof replacement. Put off the repairs for too long, however, and small problems with your roof could spread leading to a deterioration of your roof deck and shingles, as well as water damage and mold or mildew indoors. To help make the determination of when to make your roof repairs, it helps to get a handle on what the cost could be.

National Average Cost of Roof Repair

According to HomeAdvisor, the national average cost of roof repairs is around $652, with most homeowners paying between $316 and $1,015. The total spread in costs, however, can extend from about $150 to $1,900.

This amount of variation in the costs of roof repair is largely due to several factors including:

  • Where you live
  • Whether it’s the shingles or the flashing that needs to be repaired
  • What material your roof is made of
  • How accessible the area to be repaired is
  • How widespread the damage is

The only way to know for sure how much your roof repair costs are going to be is to get an estimate from a qualified roofing professional. If you’re able to discover some things about the problem that needs to be repaired, however, you may be able to get a general idea of what the final cost is going to be before you call.

Typical Causes of the Need for a Roof Repair

The need for a minor roof repair is fairly common, and there are several different things can affect your roof and cause a need for repair at any given time. None of these problems is extremely serious on their own; left alone, however, the damage could spread and cause the need for a total roof replacement, rather than a simple repair. If your roof is leaking or showing signs of water infiltration, take a look for any of the following:

  • Missing shingles: No matter what material you roof is made of, you may lose some shingles over time. They could be knocked off in a storm, or blown off by a heavy wind.
  • Cracked, dented, or damaged shingles: Tile, asphalt, and slate shingles can also be cracked, dented, or damaged in a storm or due to things like falling tree limbs or hail.
  • Leaking flashing: Sometimes it’s not the shingles themselves that are the cause of the problem, but the flashing that surrounds things like skylights, chimneys, and windows.
  • Ice dams: Melting snow and ice on your roof can refreeze at the edge causing an ice dam. This can allow water to back up under your shingles, causing them to deteriorate at a faster rate.
  • Valleys: Water can collect wherever you have a valley or a low spot on the roof, causing shingle deterioration and leaks.
  • Low pitch roofs: A roof with a low pitch is more likely to sustain damage during storms.

Any of these types of damage, as well as unseen damage that leads to water coming into your home needs to be addressed right away. Sometimes these signs can’t be seen from the ground, but you may find signs of water damage, mold, or mildew in your attic which can indicate a problem.

Common Roof Repairs for Different Materials

Ultimately, it doesn’t matter what’s causing the leak – it still needs to be addressed before the problem worsens. The most common causes of a need for roof repair, and their average repair costs, follow.

Asphalt Shingle Roofs

According to Home Advisor, correcting the most common type of problem on an asphalt roof, such as shingles being torn off in a high wind or being damaged during a hail storm costs around $250.

Metal Roofs

The cost of a metal roof repair is generally around $300. The most common type of problem with this roofing material has to do with the seams not being fastened properly, which allows moisture to infiltrate.

Wooden Roofs

The average cost to repair a wooden shake roof is around $360. Problems like moss build up may cause the shakes to deteriorate and need replacement. You may also find insect activity if the shakes were not properly treated.

Slate Roofs

Slate roofs cost about $530 to repair – the most expensive type on average. Common problems usually stem from improper installation causing a tile to stick up slightly if it has been nailed down too hard. This type of roof is also very prone to ice dams and the leaks that go with them.

Tile Roofs

The cost to repair a tile roof is around $350 on average. Common problems include tiles deteriorating n the heat of the sun and buckling, which can allow water to infiltrate. It’s also possible for some tile roofs to leak all the time, letting water collect on the underlayment on the roof deck. Eventually, this underlayment will fail, letting the water into the house.

Flat Roofs of All Types

Just about any flat roof including those made from foam and tar will cost about $400 to repair on average. As flat roofs age, they tend to sag in the middle, which can allow water to begin to collect and build up on the surface. Over time, the water will begin to break down the roofing material, forcing itself through the roof and into the roof deck below where it can cause further sagging and water damage.

Other Roof Repair Costs and Considerations

In addition to the flashing and the shingles, you may also find that your roof may need repairs to the fascia, soffits, gutters, and trusses. All of these areas are prone to things like cracks, water damage, and rot, which can spread to other areas of the roof and roof deck. At the time of your roof repair, your roofer may find other forms of damage that you were unaware of. These can add to the total cost of your roof repair.

Labor Costs

Factoring into the total cost of your roof repair is the cost of the labor. This is dictated largely by the area you live in, but keep in mind that the accessibility of the area that needs repair could play a role as well. For example, a town house or attached house may be more difficult to reach, making the repair take longer, which can drive up your total labor cost and the total cost of the repair.

On average, the labor cost for roof repair nationally runs between $45 and $75 an hour, with the final cost being dictated by the type of roof, how widespread the damage was, and how easy the damage was to reach. Labor costs in Phoenix, AZ are usually in the middle, in the neighborhood of $60 per hour.

  1. This is some great information, and I appreciate your point that a slate roof is prone to ice dams which cause leaks. My husband and I just moved into a new house, and the roof is made up of slate. There are some ice dams already forming, so we’ll definitely look into having those removed and any damage repaired right away. Thanks for the great post!

  2. It looks like slate roofs are the most expensive to repair. I guess it makes sense because they are actual stone, and not just a mad made object. I need to get a new roof, and I am leaning towards metal or slate. Thanks for the heads up on repair costs!
