You may know that asphalt shingles deteriorate over time and require periodic replacement in order to keep your home in good condition, but do you know how to check the condition of your asphalt shingles? Climbing onto your roof with a ladder is dangerous – it's a common source of home injury, and you run the risk of damaging your roof by walking on it. To keep yourself safe, here are a few ways to monitor the condition of your asphalt shingles without climbing up a ladder.
Use a Drone
Drones equipped with high-resolution cameras are a safe and easy way to check the condition of your asphalt shingles. If you own one or have access to one through your friends, you're in luck. You simply pilot the drone above your roof and take pictures of your shingles. You'll have to maneuver the drone fairly close in order to get usable images – be careful not to accidentally collide with your roof.
Transfer the pictures to your computer and open them up to check the condition of your shingles. Missing or broken shingles are obvious – you'll either see the exposed underlayment or the roof sheath if the underlayment has already worn away. Damaged shingles are slightly harder to spot. When ultraviolet light causes the shingles to deteriorate, the asphalt begins to peel away from its backing. When it's no longer securely attached, the asphalt will be carried away by wind and rain.
That means the surface of a shingle that's deteriorated to the point where it requires replacement will be pitted and uneven. Spotting them requires multiple high-resolution photos from different angles. Missing shingles, broken shingles and damaged shingles all need to be replaced by a roof repair professional in order to prevent rainwater and pests from getting through your roof and into your home.
Get a Pair of Binoculars
A pair of high-powered binoculars gives you the level of detail you need to survey the condition of your roof. Stand a distance away from your home and zoom in on your roof. You need a pair of binoculars that lets you look at individual shingles – looking at shingles in a group causes them to appear to blend together, which makes it difficult to determine their level of deterioration. Make sure that you're able to see your entire roof. If there's a nearby hill, that can make a great vantage point. As with using a drone, you're looking for gouges, pits, and unevenness on the surface of your asphalt shingles.
Call a Professional
If you don't have a drone or a pair of binoculars, just call a roofing repair professional to inspect the status of your roof. They'll come to your home and perform a full inspection, checking the condition of your asphalt shingles as well as ensuring that your chimney cap is tight and the flashings on your roof are free of rust. Hiring a professional means that you don't have to do it yourself. In addition, an expert is better equipped to accurately judge the condition of your roof and determine if it needs replacement.
Keeping a close eye on the condition of your roof is important to protect your home – damaged shingles let rainwater enter into your home, causing water damage and mold. They're also a potential entry point for nuisance pests like mice and rats. Survey your asphalt roof regularly to check for damage, and call a roof repair professional if you notice missing, broken or damaged asphalt shingles.
