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.

Every spring and after storms

Typical Costs

Repair: $350 – $1,400

20 years

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 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.

Pro Tip

You can use a 50/50 mix of bleach and water to clean your composite roof. Spray the shingles with the solution, let it sit for 20 minutes, and rinse with a low-pressure hose.
