Roof Moss Leaks in West Seattle

Moss grows between and under shingle edges, lifting them so rain can blow underneath. It also acts like a sponge, keeping the roof wet for days after rain and feeding rot in the decking.

North-facing slopes, roofs under big firs and cedars and low-slope sections stay damp longest and grow the most moss.

Roofers brush moss off gently from the top down and treat the roof with a moss control product. Pressure washing damages shingles and is best avoided.

Trimming overhanging branches lets sun and air reach the roof. Zinc or copper strips near the ridge release minerals that slow moss growth when it rains.
