Assessing the Condition of Your Roof
Even the most durable roofing materials have finite lifespans. After years of protecting your home from all sorts of environmental threats, sooner or later your roof will need a little TLC. In some cases, you might just need to replace a few worn shingles. In others, when wear and tear is more widespread, it can be more cost-effective to invest in a full roof replacement. But before we start thinking about doing any repairs, let’s take a closer look at your roof to determine what kind of condition it’s in.
Different roofing materials are rated to last different lengths of time. Whereas a slate roof can last close to a century, asphalt shingles typically last between 20 and 30 years depending on their quality. If you know your roof is approaching the end of its expected lifespan, you should be on the lookout for signs of wear.
Curling and Buckling
As shingles wear they often start to warp – typically either curling from the corners or buckling in the middle. Damage from debris and precipitation can exacerbate this problem. A few curling shingles here and there are easy enough to replace individually, but if you notice curling and buckling across large sections of the roof you should consider a full roof replacement.
The mineral granules on asphalt shingles are designed to make them durable and weatherproof. Over time, these granules deteriorate and fall off of the shingles, compromising their ability to protect your roof from leaks. The process of granule loss tends to accelerate as shingles get old and worn. Large patches of discoloration on a roof are common indications of extensive granule loss. You can also check your gutters to see if they’re accumulating fallen roof granules.
Because they channel moisture down the roof and into its gutter system, roof valleys are especially important and sensitive components of your home’s roof. Likewise, if you notice any shingle damage or widespread granule loss in roof valleys, you should take steps to repair the damage as soon as possible.
