You pride yourself on taking care of things—your family, pets, car, belongings, and, of course, your house. But are you truly taking care of every aspect of your home? As it turns out, even the most attentive homeowner can miss the root causes of roof damage, namely curling or buckling shingles.
At Certified Roofers & General Contractors, Inc., we want to inform you of the most common reasons behind shingle curling so that you can take the preventive and proactive measures needed. This way, you can easily recall the top signs of wear the next time you inspect your roof.
The question we need to answer is quite simple: what exactly causes curled shingles? Is it the weather, or maybe just the type of material you chose? While weather plays a role, most of the possible causes of curling shingles actually involve installation and upkeep.
The Top 5 Causes of Curling Roof Shingles
1. Old Age
If your roof is passing the decade mark, it may be time to outright replace the shingles. Roof shingles naturally wear down with age and exposure to the sun. If this is the case, it is ideal to update your roofing sooner rather than later. If left to age further, the shingles will only become more brittle, curl, and eventually snap off.
2. Poor-Quality Materials
If a previous contractor was looking to save a few bucks, they might not have chosen the optimal material to work with. High-quality manufacturing ensures your shingles can withstand the severe weather and daily wear and tear they are subjected to. Low-quality shingles will curl and fail much faster.
3. Incorrect Installation
Maybe that friend of a friend you hired last time was not exactly an expert on roofs. If shingles are not nailed down correctly or the alignment is off, they will eventually lift and buckle. Always consult with licensed contractors, such as our team, to be certain the job gets done flawlessly.
4. Improper Attic Ventilation
We all know that heat rises, which is why your attic is generally the warmest part of the home. The issue with this is when attics lack proper ventilation, heat and moisture become trapped beneath your roof deck. This bakes the shingles from the underneath, causing them to curl rapidly. It also leads to mold, which can result in serious and long-term structural damage.
5. Shingles Installed Over an Existing Roof
While it may be cheaper to lay new shingles directly over an existing roof, bypassing the tear-off process means you risk the new shingles curling. Layering prevents the new shingles from attaching securely to a flat surface and sealing correctly, causing that dreaded buckle.
