Why Roof Moss is a Serious Problem in Tigard

Tigard’s rainy climate provides the perfect environment for moss to thrive. While it might seem harmless at first, moss can cause serious damage to your home if left untreated.

The Risks of Roof Moss Include:

Water Retention: Moss soaks up and holds moisture, weakening shingles and roofing materials.
Shingle Damage: As moss grows under shingles, it lifts and loosens them, leading to leaks.
Structural Rot: Moisture trapped under moss can rot wood, rafters, and support beams.
Pest Attraction: Damp, mossy areas attract insects, rodents, and birds.
Decreased Curb Appeal: Moss-covered roofs look neglected and can lower property value.

Regular roof moss removal in Tigard isn’t just cosmetic—it’s vital to maintaining the integrity of your home.
