Identifying Damage On An Asphalt-Shingle Roof

Posted on: 4 March 2015


Asphalt shingles are an economical roofing material, but if you want to keep you want to get the most longevity from your roof, you need to make sure you take care of your roof. If a little leak goes undetected, it can compromise the remaining shingles on your roof. Thus, you want to inspect your roof for leaks frequently and take care of any leak you find quickly. 

What Can Cause Roof Damage?

If you know what can damage your roof, you know when you should be looking for signs of damage. The biggest thing you have to worry about is the weather. Hail can scrape the protective granules off of your shingles, and once these granules are gone, the sun can bake the volatiles out of your shingles, which makes them brittle. Cracks can then develop, and there is a very small line between a crack and a leak. Wind can also tear your shingles along the seams and cause leaks. 

How to Spot Leaks

Knowing when to look for damage is important, but you also need to know what roof damage looks like:

  1. Signs of Hail Damage—The damage hail can cause depends on the size of the hail that falls. Smaller pieces of hail are enough to scrape the protective granules off of your roof. After a hailstorm, you should check your rain gutters and downspouts for a buildup of granules. Larger hailstones can punch bullseye-shaped cracks into your roof shingles. 
  2. Wind Damage—A strong wind will catch the lower edge of your shingles like a sail. If the wind is strong enough, it will rip seams. A gale-force wind will rip the shingles right off of your house. Thus, after a windstorm you should check your roof for torn and/or missing shingles. 

Once you have spotted roof damage, you have to decide whether it is more cost-effective to repair or replace your roof. Repair is cheaper, but only if you don't have a lot of damage to worry about. Replacing a roof will cost around $8,000. As long as your bid to replace your roof costs less than $8,000, it is cheaper to repair a roof. You can keep the costs for repairing a roof down if you do the repairs yourself. However, if you don't feel comfortable making your own repairs or climbing around on your roof, you can always hire someone like Burroge Construction LLC to make the repairs for you.
