Roof moss questions, answered

Plain answers for Salem-area homeowners.

Does it cost anything to request a quote?

No. Requesting a moss removal quote is free and you are under no obligation.

Who will contact me after I submit the form?

A local moss removal company that serves your area, by phone or email, to talk about your roof and arrange a quote.

Is moss really that bad for my roof?

On asphalt and metal roofs, moss does not eat the material, but it holds moisture and can lift shingle edges so water reaches the layers below. On cedar shake it can degrade the roof more directly.

Can I pressure wash it off myself?

OSU Extension says improper pressure washing can damage shingles, and that experienced users may do it. When in doubt, hire a professional or use a long-handled brush. Roofs are also dangerous when wet and mossy.

How much does moss removal cost in Salem?

HomeAdvisor lists a Salem average of about $420 for roof cleaning, with a typical range of $290 to $573. See our cost guide.

When is the best time to do it?

Moss treatments work best when moss is actively growing and followed by dry weather. Early spring and early fall are common choices. See when to treat.

How long until it grows back?

It depends on shade and moisture. Cleaning does not change the conditions that grew the moss. OSU recommends an annual maintenance routine after removal.

Do zinc strips work?

Oregon State resources describe removal followed by zinc strips as an effective long-term approach. Strips can leak if installed badly and zinc runoff can harm aquatic life. See prevention.

Does moss grow on metal roofs?

Rarely. OSU notes moss does not easily take root on metal roofs.

How do I check a company is legitimate?

Ask for their Oregon CCB license number and look it up on the state's CCB website, and ask for proof of insurance. See how to hire.

Is Salem Moss Removal the company that does the work?

No. We are an independent referral service. A separate local company does the work.
