Asphalt roofing is durable and low-maintenance, which is why asphalt has become one of the most popular materials for modern roofs. But low-maintenance doesn't mean no maintenance and some simple checks, with follow-up fixes, can keep your roof in good condition for decades to come.
Note that you should only physically climb onto your roof if you have the proper safety equipment. You can check for signs of damage from the ground using a pair of binoculars and then either obtain the safety equipment or call in a roofing contractor (such as one from Rainy Day Exteriors) for assistance.
Moss or Algae
Moss and algae can both end up on your roof due to nearby trees and windy weather. If the moss and algae sit on your shingles for an extended period of time, dark stains can appear that are difficult to remove. The materials can also trap moisture onto the shingle, which can cause water damage.
You can treat existing and recent moss and algae buildups, and staining, by applying a diluted bleach spray – think at least two parts water to one part bleach – and then following up with a stiff-bristled brush or broom. Longstanding stains might not come out and you will either need to accept the cosmetic flaw or contact your roofing contractor for more shingles.
Do moss and algae continuously end up on your roof? Ask your contractor to install copper strips along the ridge of your roof. When it rains, the water will carry chemicals from the copper that kill off mold and algae.
Loose or Cracked Shingles
Asphalt shingles are fairly lightweight and can become loosened over repeated exposures to windy conditions. If you've had a recent bout of bad weather, conduct a visual inspection to see if any shingles came loose. The loosened shingle can be easily reattached using roofer's cement as long as the shingle isn't damaged.
What if you see cracked shingles following a storm? Call in a roofing contractor for an assessment and to most likely replace the shingles. The cracks are an excellent way for moisture to get underneath the shingle, which poses the risk of causing water damage to the roofing material below.
Curled or Buckled Shingles
When you look at your roofing, do you see a number of curled or buckled shingles? The cause is likely water damage that has happened underneath the shingles and caused the fasteners to loosen and the shingles to warp.
If you see signs of curled or buckled shingles, call your roofing contractor to replace the damaged roofing as soon as possible. The problems will only get worse with time and will leave your roof's underlayment vulnerable to even further water damage. Water can also start to seep into your home.
