Denver Roofing Company Explains Why Shingles Curl


January 18, 2017

Do you have an asphalt shingle roof? If so, you’ve probably been told time and time again that curling shingles are one of the first signs you may need to call a Denver roofing company. It’s true that curled shingles do signify it’s time for a repair or replacement—but what causes shingles to curl in the first place?

Installation Errors

If you did not hire a qualified roofing contractor to install your roof, the shingles could be curling because of installation errors. Contractors must follow specific instructions when installing asphalt shingles, so if they use the wrong number of nails or don’t secure each piece properly, the shingles may begin to curl shortly after installation. Shingles can also begin to curl shortly after installation if they were installed while wet.

Time for a Replacement

Unfortunately, sometimes shingles begin to curl because they’ve reached the end of their lifespan and are beginning to deteriorate. Asphalt shingles can last anywhere between 20-40 years, however most are only under warranty for 15-20 years. Think back to the last time you had your roof replaced. If it’s been at least 15 years, it could be time for a replacement. If this is the case, you will need to contact a roofing professional to schedule the installation of a new roof.

Two Layers of Shingles

Some homeowners choose to lay a layer of asphalt shingles over the existing shingles on their roof instead of ripping out the old ones and replacing the roof. This is a cheap alternative to a complete roof replacement, but it will not hold up for long. No matter how experienced the roofing contractor is, it’s almost impossible to line the layer of new shingles perfectly on top of the existing shingles. Because of this, the new shingles will not fit snugly in place, and they will begin curling during extreme weather conditions such as hail storms or high winds.

Shingle Issues

It’s possible the reason your shingles are curling is because the asphalt used on your roof is defective. Some shingles are not made correctly, so they will not hold up as well as those that have been properly manufactured. This is another reason why it’s so important to take your time and hire a qualified and experienced roofing contractor to handle all of your repairs and replacement jobs. Reliable roofing companies will only work with manufacturers that they trust to provide them with high quality materials so their clients do not have to worry about this issue.
