How old is your roof? Most homeowners don’t know—and even if you think you have a pretty good idea, how sure are you?
Knowing how old your roof is can help you anticipate problems before they occur and take proactive steps to prevent them. If you have an asphalt shingle rooftop, it can also let you know whether your home is a good fit for roof rejuvenation treatments like Roof Maxx, which can add up to 15 years to the lifespan of your shingles at up to 80% less than the cost of a full roof replacement.
So below, our team shows you how to find out how old your roof is with four different methods that all really work. Keep reading to estimate your roof’s age and learn what to do if it’s nearing the end of its lifespan.
If your home was built or had its roof replaced within the past few decades, there’s likely a record of it in your local building department. Requesting a copy of the building permit is often the best way to get an answer about your roof’s age, since it’ll tell you exactly when the roof was installed.
If you purchased your home from someone else, they might have records or receipts from the last roof replacement. Reach out to them, or check any documents provided during the home-buying process, like inspection reports or warranties.
If you know which company worked on your roof, they may have records of the installation date. Even if you’re unsure, a quick look at shingles or other materials for branding or markers might help identify the manufacturer or installer.
If all else fails, professional roofers can provide an estimate based on the condition of your shingles, flashing, and other factors. While not as precise as documentation, their expertise can help pinpoint an approximate age and identify any urgent maintenance needs.
Even if you know your roof’s age, understanding when it needs replacement is just as important. Most roofs last between 20 and 30 years, depending on the material. However, signs of wear and tear can accelerate the need for replacement.
Common signs your roof might need a refresh include:
Curling, buckling, or missing shingles suggest your roof’s protective layer is compromised. Shingles in poor condition allow water to seep through and cause further damage, like rot or mold growth.
Shingle roofs don’t always need to be replaced outright. If your shingles are older but still in generally good condition, you can use Roof Maxx to help them last longer by restoring the oils they’ve naturally lost over time. It’s usually just when your shingles are cracked, broken, or missing that a replacement may be your best option.
Granules protect shingles from the sun and elements, and their loss can leave your roof vulnerable to damage. If you notice granules collecting in gutters or on the ground after storms, your shingles may be nearing the end of their lifespan. Bald patches on your roof are a clear sign action is needed.
This is another case where you may not need to replace your entire roof. Although losing granules can eventually weaken your shingles and make them vulnerable to breakage, roof rejuvenation treatment can significantly slow down granule loss and help your shingles last longer.
Stains in your attic, ceiling, or walls indicate water is getting through your roof. This usually results from problems with flashing, chimneys, skylights, or places near the walls—where your roof is most vulnerable to water ingress.
Left unchecked, water damage can weaken your home’s structure and lead to expensive repairs. A Roof Maxx treatment intended to leak-proof your roof, since it strengthens the flexibility and durability of your shingles instead of affecting those other areas. But we do offer an optional roof tune-up package that can help minimize and prevent leaks. Contact a Roof Maxx dealer near you to learn more.
While moss and algae may seem like minor nuisances, they trap moisture that speeds up the decay of roofing materials. Over time, this compromises the roof’s ability to protect your home.
Roof Maxx acts as a natural fungicide that prevents new moss and algae growth. If your shingles are already covered in these growths, it’s best to have them professionally cleaned before evaluating the condition of the shingles underneath.
Replacing a roof is a major investment, which can routinely cost around $20,000-30,000—but not every aging roof needs immediate replacement.
