20-30 Minute Assessment

Composite Roof

Composite roofing is lightweight and resists water, fire, and insects. Some composite products also resist organic growth like mold or moss.

While they’re waterproof, poor installation, cracks, or loose shingles can let water in. Cold weather can make composites brittle and prone to damage from impacts or pressure.

Steps to Assessing Your Composite Roof


Step 1: Look for cracked, displaced, or missing shingles. Pay attention to the valleys where different planes of your roof meet. Shingles in these areas often become loose, and gaps could allow water into your home.


Step 2: 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. If you see any of these issues, address them immediately.


Step 3: Remove anything growing on your roof. Moss, lichen, mold, and vines can damage it.
