In the Vancouver, WA area, composition roofs are found on over 75% of homes! Composition roofs refer to those using shingles made from composite materials like asphalt. Generally speaking, there are 3 main types of composite shingles– 3-tab, Presidential, and Architectural shingles.

3-tab composition roof shingles are the most basic, inexpensive, and least durable option. They are flat, with shingle having 3 tabs. For many homeowners, they represent a low-cost alternative to more decorative and traditional materials like cedar shakes and tiles. Architectural and Presidential composition roof shingles are heavier duty designs, that add dimension and protection to your home’s roof.

No matter what type of composition roof shingle you may choose, proper maintenance is the key to maximizing the life of your home’s roof!

After you’re done working on my composition roof, will you handle clean-up and disposal?

Of course! When you hire the roof experts at Northwest Roof Maintenance, you don’t have to worry about a thing. We’ll leave your roof strong, sturdy and sparkling clean!

Can I pressure wash my composition roof?

No, high pressured water can deteriorate and disintegrate the composition materials. In fact, many manufacture and installment warranties are voided if the roof is pressure washed. When it comes to composition roof maintenance, the best option is hand brushing with a metal wire brush, followed by a zinc sulfate treatment.

How often should I have my composition roof serviced and maintained?

There are no hard and fast rules when it comes to deciding how often to have your composition roof cleaned. But if you notice any moss growth, loose or lifting shingles, missing shingles, leaks, or animal activity, you should have a professional roofer inspect your roof to see what maintenance might be needed.
