Roof Cleaning
Katy, TX.

Katy's newer residential construction — most homes in Cinco Ranch, Cross Creek Ranch, and Cane Island built after 2000 — uses standard dimensional asphalt shingles that are particularly susceptible to Gloeocapsa magma algae. The prevailing southeast wind in the Greater Houston area carries algae spores from older colonized roofs to newer ones, meaning a clean roof in a neighborhood with several stained roofs will typically show first streaking within 18–24 months. Black streak algae on Katy roofs is not a sign of age — it's a climate-driven biological growth issue that soft washing resolves.

We use the ARMA-recommended soft wash method: low-pressure sodium hypochlorite application that kills the algae colony without lifting shingle granules or voiding manufacturer warranties. All landscaping, gutters, and siding are pre-wetted and protected before the cleaning solution is applied. Post-clean rinse is thorough and directed away from garden beds. Results are immediate and visible — roofs treated with this method remain clean for 2–4 years depending on shade level and nearby untreated roofs.
