When your asphalt shingle roof starts leaking or shingles start peeling, you have a decision to make. Should you have the roof repaired or is it time to replace it entirely? The distinction is not always a clear one. To help determine which is the better choice for you, follow these guidelines.
How old is your roof?
Over 20 Years: The average asphalt shingle roof has a life expectancy of about 20 years. So if your roof is 20 years old or older, you might just be wasting money if you repair it since it's likely on its last legs. Replace your roof, and you'll avoid problems that might arise in the coming months and years.
Under 20 Years: If your roof is less than 20 years old, the repairs it needs are likely to be pretty minor. Put some work into it, and the rest of it will probably last a while before needing to be replaced.
How extensive is the damage?
Isolated to One Section: If the shingles are only peeling in one section or if there's just a leak in a specific area, then having the roof repaired is wise. There's no sense ripping off the rest of the roof since it seems to be in good shape.
Spread Out: If there peeling shingles scattered all over the roof, replacing the entire roof might be your best option. Patching all of these little areas could end up being just as costly as a replacement, and if that many areas are failing, the remaining shingles probably aren't in great shape either.
Is the roof sagging?
Yes: If the roof appears to be sagging or buckling in a certain spot, this means that water has been working its way under the shingles for some time, causing the wood underneath the shingles to erode. There's no good way to fix this without replacing your whole roof -- and you should replace it ASAP since a sagging roof is at risk for collapse.
No: If the roof does not appear to be sagging, then rely on the other factors on this list to determine whether to replace or repair it. Keep in mind that in order to prevent the wood from deteriorating and causing your roof to sag, you must make repairs promptly.
