Protecting Oregon roofs from the Pacific Northwest elements.
Left untreated, moss actively damages your roof and costs you money.
Moss roots work their way under shingles and pry them up. Over time this exposes the underlayment and decking to water, leading to leaks and rot that cost thousands to repair.
Moss acts like a sponge, holding moisture against your roof long after rain stops. This constant dampness accelerates material breakdown and feeds mold growth in your attic.
A moss-covered roof can lose years off its expected lifespan. Regular removal and prevention treatment is far cheaper than an early roof replacement — and protects resale value.
A careful, three-step approach that removes moss without damaging your roofing material.
We walk your roof and assess the extent of moss growth, the condition of your shingles, and any areas that need extra attention before we touch anything.
We use a low-pressure, manual removal process — no power washers that blast off granules. Every bit of moss is removed by hand or soft brush to protect your shingles.
Every service includes a basic prevention treatment at no extra charge. We'll also help you choose the right long-term option — zinc strips, spray treatment, or a maintenance plan.
Our careful removal process restores your roof's appearance and protects it for years to come.
