Asphalt Shingle Roof

Maintenance is important. Small cracks or a single missing shingle can lead to moisture problems like rot and mold.

Safety Tip

Falls from ladders are common. Stay in your comfort zone. Set your ladder on a stable surface, lock the spreaders, and maintain three points of contact. Consider hiring an insured pro for jobs above the first floor.

Steps to Assessing Your Asphalt Shingled Roof

Step 1: Look for missing, loose, or cracked shingles. Damaged shingles can allow water into your home and should be repaired immediately.

Step 2: Blistered or rippled shingles may indicate a deeper problem, such as improper attic ventilation, damaged underlayment, or installation issues.

Step 3: Inspect the flashing. You’ll see it where the roof meets things like chimneys, vents, and skylights. Look for corrosion, holes, cracks, missing sealant, and gaps. These issues should be addressed immediately.

Step 4: If your shingles look brittle or curled at the edges, or if they’re missing the surface layer of grit, your roof cover may be at the end of its life. Contact a roofing professional right away.

Step 5: Remove anything growing on your roof. Moss, lichen, mold, and vines can damage it.

Pro Tip

The grit from asphalt shingles can collect in your gutters, which adds unnecessary weight and can cause clogs. Clean your gutters at least once a year.
