Common signs in Vancouver homes include higher-than-usual energy bills, damp spots or water stains on ceilings, and a musty odor in your attic. Moisture trapped in insulation reduces its effectiveness and can lead to mold. We recommend a professional roof inspection, especially after our rainy season, to assess insulation health and ventilation.

Those dark streaks are often Gloeocapsa magma algae, which thrives in our humid climate. While DIY cleaning with a bleach solution is possible, improper pressure washing can damage shingles. Our professional cleaning service uses safe, EPA-approved algaecides and low-pressure techniques to effectively remove stains without harming your roof's warranty or lifespan.

Prevention is key. We advise Vancouver homeowners to schedule bi-annual inspections (spring and fall), keep gutters clear to prevent water backup, and ensure attic ventilation is adequate to reduce moisture buildup. Trimming overhanging tree branches also minimizes shade and debris that encourage algae growth. A small maintenance step can prevent major repairs.
