If Your Previous Roof Decayed Prematurely, Look For Shingles With These Features This Time Around

Asphalt shingles typically last around 20 years. Architectural shingles last about 50 years. If your old roof decayed quickly and your shingles did not last this long, then chances are, your home is exposed to some conditions that really challenge the shingles. This time around, it will be worth your while to choose shingles that are better made to withstand these challenges; as a result, your new roof should last longer. Here's a look at some shingle features to consider.

Algae and Moss Resistance

Is your roof under a lot of shade? Does it rain a lot where you are? Have you noticed black streaks running down your shingles or patches or moss growing between them? Plant growth can greatly decrease the life of your shingles, and shady, moist roofs are very prone to moss and algae. You'll have fewer issues if you purchase shingles that are meant to be algae and moss-resistant. Usually, these shingles have zinc or copper embedded in the granules. When the shingles get wet, these metals release ions into the water. Algae and moss won't grow in the zinc or copper-infused water.

Wind Resistance

Are you noticing missing shingles after storms and after windy days? If the shingles are not blowing off completely, they may be beginning to peel away in the corners. Look for shingles that are made to be wind-resistant this time around. Even if you're not in a hurricane zone, your home may be angled in a manner that allows the prevailing winds to catch under the edges of shingles. So, shingles made to withstand heavy winds will be less likely to lift off of the roof or peel away from it. Typically, these wind-resistant shingles are heavier than standard asphalt shingles and they also have stronger adhesive along their edges.

Light Color

If you live in a very sunny area, the sunshine may be to blame for your premature shingle deterioration. The heat causes the adhesive and asphalt to break down prematurely. Lighter-colored shingles won't have this problem as extensively. This is because the lighter colors reflect more sunlight rather than absorbing it. (It's the same concept as wearing lighter-colored clothing to stay cool in the hot weather.) Tan, white, or pale green shingles are becoming more common, so you should not have trouble finding a color you love.
