Roofing Services · Central Valley, CA
Dark streaks and green growth do more than look bad. SQ Roofing Inc. (Supreme Quality Roofing Inc.) removes algae and moss from shingle and tile roofs using methods that protect your roofing material.
What’s Growing on Your Roof
The black streaks and green patches on many Central Valley roofs are algae, moss, and lichen. They grow where moisture lingers, on north-facing slopes, under trees, and in shaded valleys, and they spread a little more every rainy season.
Over time, that growth holds water against the roof surface, loosens shingle granules, and works into the gaps between tiles. Heavy moss can also keep water from draining properly, pushing it under the roofing and toward the decking.
SQ Roofing Inc. (Supreme Quality Roofing Inc.) cleans roofs with methods chosen for your specific material. High-pressure washing can strip granules and crack tiles, so we use controlled cleaning techniques that remove the growth without damaging what’s underneath.
Know the Warning Signs
Algae and moss are easiest to remove before they take hold.
Streaking that runs down the slope, especially noticeable on lighter roofs.
Moss or lichen along tile edges, ridges, and shaded areas.
Roofs under trees stay damp longer and grow algae faster.
A clean roof makes a strong first impression on buyers and neighbors.
