Tile and asphalt shingle both sit on Pinellas Park roofs, and neither one should ever meet a pressure wand. Tile cracks; shingle loses the granules that protect it. We run biodegradable biocide at 100–500 PSI, which kills the algae at the root and leaves both surfaces — and their warranties — intact.
Typical Pinellas Park ranges: shingle $600–$1,800, tile $750–$2,200, metal $550–$1,600, depending on square footage, pitch, and growth level. Every quote is free and returned within 24 hours. Full method on our roof cleaning service page.
