How often do you really go outside and inspect your roof? Do you know if your shingles are curling or blistering? Does your roof have bald spots or decay that needs to be addressed? Have you noticed these things, but you’re just not sure what they mean? It’s important to know what your home needs, particularly when it comes to your roof, which can impact your home’s energy efficiency and resale potential.
Note: If your shingles are loose, dislodged, curling, or blistered, do NOT walk on the roof to inspect it. There is an increased risk of doing additional damage to the roof as well as getting injured.
Do You Need Roof Replacement?
Missing shingles – Asphalt shingles can be dislodged or blown away by heavy winds or when the shingles begin to lose their tar seal. When the tar strip loses its seal, there’s very little that can be done to keep your shingles in place. You can try temporary tar sealing or replacing the missing shingles, but that isn’t likely to work in the long run. In many cases, when your home begins to lose its shingles, it’s a sign you need roof replacement; however, it’s a good idea to consult a professional roofing expert to discuss the correct course of action.
Curling – There are a lot of reasons why your asphalt shingles could start to curl—lack of back coating, improper fastening, and most importantly, a lack of ventilation. Curling shingles will eventually break off or crack, which can leave your home susceptible to leaking and, as a result, diminished energy efficiency. To determine if your roof shingles are curling due to poor ventilation, it’s important to have your roof and attic inspected because if the underlying problem isn’t addressed, it will happen again with your new roof.
Blistering – When too much moisture gets into your roofing shingles, they will begin to blister. As they begin to bubble and blister, the shingles will lose their seal to the roof tar and, in most instances, will become dislodged.
Granule loss – Although a small amount of granules will be loose after being freshly installed, if there is a significant amount of granule loss on your shingles exposing the asphalt or underlying mat, roof replacement will be needed to fix it.
Rotting – Although this problem is most common with organic-based shingles, rotting can occur in any type when the mat at the core of the shingles begins to absorb moisture. One of the greatest concerns of rotting shingles or roof wood is how easily rot can spread to other areas of the roof. Make sure to address this problem immediately.
Stains on interior walls and ceilings – If there are stains and water spots on your interior walls or in your attic, that’s a sure sign your roof is leaking. Roofing contractors can evaluate your home and determine the cause of the leaking and the best avenue for repairing or replacing your roof.
Buckling – This is another common roof problem that has a number of potential causes including roof deck movement, wrinkled underlayment, poorly applied felt, no spacers between roof deck boards, and poor roof ventilation. A roofing professional can help you determine what the cause of your buckling is, but generally, this kind of problem requires roof replacement.
Leaking – It almost goes without saying, but if your roof has a leak, it may be time for a roof replacement. While one or two leaks can usually be patched and repaired, if the leaks are numerous or persistent, it may be necessary (and cost-effective) to replace your roof altogether.
Steadily increasing energy bills – If you’ve been noticing a steady rise in your monthly utility bills, a good place to investigate is your roof. When your roof is failing, it can allow air to escape and enter your home, making it more difficult to maintain a comfortable indoor temperature and cause your heating and cooling systems to work harder.
Age – Shingles have a lifespan of 20-50 years, based on a certain number of factors, including weather conditions, what they’re made of, quality of installation, and regular maintenance. As your roof shingles begin to age, it’s a good idea to start thinking about a roof replacement.
Debunking Roofing Myths
Many people believe that dark spots where mold and algae growth are occurring are a cause for roof replacement. However, unless the mold and algae are contributing to deeper wood rot in your roof, it’s only an aesthetic problem that requires cleaning.
