When I think window or roof cleaning- i think Cornerstone Cleaning!Posted on Rich EmersonApril 13, 2026Trustindex verifies that the original source of the review is Google. On time and efficient.Posted on Deb ButlerApril 10, 2026Trustindex verifies that the original source of the review is Google. I had Cornerstone come out and give me an estimate on cleaning my roof. An appointment for the estimate was made, the price was right and the service was scheduled. The roodf hadn't been cleaned in a few years and the gutter covers had to come off. The first day the crew had issues with their pump and couldn't finish the job the first day, but promised they'd be back in the morning. They were on time, got the job done and did a great job! I highly recommend their service!Posted on Stephen PattApril 2, 2026Trustindex verifies that the original source of the review is Google.

Roof Cleaning Frequently Asked Questions
Why do roofs need cleaning?
Roofs accumulate moss, algae, and organic residue that can trap moisture, accelerate shingle wear, and shorten roof lifespan. Regular roof cleaning removes this buildup and improves performance while extending life.
How often should roof cleaning be done?
Most roofs benefit from cleaning every 1–3 years, depending on tree coverage, moisture exposure, and local climate conditions.
Can roof cleaning damage shingles?
No — when professionals use soft washing, which applies cleaning solutions and low-pressure rinsing rather than high pressure that can strip granules or damage roofing materials.
Is moss removal necessary or just cosmetic?
Moss removal is both cosmetic and preventative. Moss holds moisture against the roof surface, accelerating deterioration and creating potential leaks over time.
When is the best time for roof cleaning in Washington?
Spring and fall are ideal because winter rain leaves organic growth behind that can be removed before heavy wet seasons set in, helping protect your roof.
Is moss on my roof actually a problem or just ugly?
It is a real problem. Moss holds moisture against shingles, which shortens roof lifespan and increases leak risk.
Â
Can roof cleaning help my roof last longer?
Yes. Removing moss and algae can significantly extend the life of roofing materials.
Will roof cleaning void my roof warranty?
No, when done using manufacturer-approved soft washing methods.
Why does my roof grow moss faster than my neighbor’s?
Shade, tree coverage, roof orientation, and airflow all affect moss growth.
How long does roof cleaning last?
Professional roof treatments typically slow regrowth for 1–3 years.
Is roof cleaning safe during cooler months?
Yes, when performed under proper weather conditions by professionals.
Is it cheaper to clean a roof or replace one?
Cleaning is far less expensive and helps delay the need for replacement.
