As you may have guessed, curling shingles are not a good sign for the integrity of your roof. But, why are your shingles curling in the first place? Let’s break down the top causes and how to fix curling shingles!
Top Causes of Curling Shingles
Curling shingles are not something any homeowner wants to see on their roof. While there are not many fixes for this issue, it is crucial to learn what is causing your shingles to curl so it never happens again. Here are the top causes to look for.
When working properly, a roof ventilation system pulls outside air in toward the bottom of the roof and displaces it toward the top of the roof. If the ventilation system is not working properly, moisture and heat can become trapped in the attic. This warmer temperature can then cause the bottom of your shingles to prematurely curl.
Shingles have a proper and an improper way of installation. It is important that you choose a licensed contractor that knows how to install the roofing system properly, including knowing how many nails to use per shingle, what type of nail to use, and what type of weather is adequate for installation. If the manufacturer specifications for installation are not followed, not only when this increase the chance of your shingles curling, but your manufacturer warranty may also be void.
Shingles may curl if they were manufactured incorrectly. While this is a fairly unlikely, in the case of manufacturer defect, there is a chance you could be covered by a warranty (assuming they were installed correctly).
Installing Shingles Over an Existing Layer
If you install new shingles over an existing layer of shingles, you are likely to encounter many problems, including curled shingles. This is because new shingles are unlikely to line up exactly with the old ones, preventing them from sealing properly. Moreover, if there is mold or rot on the existing roof, this will cause problems on the new roof installed above it.
Shingles may also begin to curl when they are at the end of their lifespan. If your shingles are old and beginning to curl, it is time to contact a trusted roofing contractor to learn about replacement options.
How to Fix Curling Shingles
The unfortunate reality is there is no quick and easy fix for curling shingles. If the shingles are only curling in a small area of the roof, you might be able to get away with a simple roof repair where we swap out the damaged shingles. But, in most cases, roofs with curling shingles need to be replaced.
Depending on what caused the shingles to curl, you might be able to work with insurance to get partial coverage, but considering the most common cause of curling shingles is old age, it is more likely to be an out-of-pocket expense.
