Moss & Algae Removal in Bothell, Washington

Moss & Algae Removal in Bothell means roofing built for the Washington climate - the heat, the humidity, and the storms. The Washington humidity and the severe storm remnants test every roof, and the tree debris covers the surface.

Signs Your Bothell Roof Needs Moss & Algae Removal

• Dark streaks on the north-facing slopes - the algae is forming in the shade
• Green patches in the shaded spots - the moss is taking hold
• Stains below the trees - the tree debris and the shade feed the growth
• Lifted shingle edges from the moss - the moss is getting under the shingles
• Damp spots that never dry - the shade and the humidity hold the moisture

Why Bothell Roofs Need Moss & Algae Removal

The humidity is the main cause. The damp air feeds the moss and the algae on the shaded slopes.

The shade is the second cause. The trees shade the roof and the sun never dries the surface.

How We Do Moss & Algae Removal in Bothell

1. Inspect the roof surface - check the shingles, the flashing, and the growth
2. Apply the cleaning solution - the low-pressure spray with the moss killer
3. Let the solution work - the dwell time breaks down the growth
4. Rinse with the low pressure - the soft wash removes the moss and the stains
5. Treat the shaded areas - the extra treatment for the moss-prone spots

Preventing Problems in Bothell

• Trim the trees over the roof - the shade and the debris feed the moss
• Clean the roof every 2-3 years - the humidity grows the moss faster
• Install the zinc strips on the north slope - the zinc prevents the moss growth
• Check the shaded sections each spring - the early treatment stops the growth

In Bothell, the algae is the roof enemy. The humidity and the shade feed the growth. The soft wash cleaning and the tree trimming keep the roof clean and dry.
