Roof Types We Clean
Customized Approach
for Every Material
We tailor our roof cleaning services in San Antonio, TX, to each of the following roofing materials’ unique requirements:

Metal Roofs (Standing Seam and Corrugated)
Metal surfaces require a gentler 3% sodium hypochlorite mix due to their smooth, non-porous nature. We often clean these from ladders, unless the pitch requires the use of safety harnesses. Special care is taken not to disturb reflective coatings. When oxidation prevents visible cleaning results, we may halt the process to prevent surface damage.

Asphalt Shingles (Case Dependent)
We only clean asphalt shingles when surface conditions permit safe treatment. Our soft wash method prevents shingle granule loss. Count on us to carefully adjust dwell time and rinsing procedures based on the fragility of the shingles.

Tile and Slate Roofs
We treat tile and slate surfaces with a 5-6% sodium hypochlorite solution, combined with a surfactant, for enhanced penetration. The mixture requires a 10-to-15-minute dwell time for effective algae removal and moss treatment. Unlike companies that use harsh pressure washing, we use soft wash techniques under 100 PSI to protect the delicate surfaces.
After the initial treatment, we visually inspect the surface and do a second application if necessary.

Frequently Asked Questions
Will roof cleaning damage my roof or void my warranty?
No. Bellows Window Cleaning follows manufacturer guidelines using soft wash methods approved by roofing brands. Most warranties actually require this type of cleaning.
What happens if another contractor shows up during the roof cleaning?
If another contractor unexpectedly arrives, we may pause the roof cleaning service for safety.
We prioritize the safety of all individuals on the property, and overlapping work—especially on or near the roof—can pose hazards. We’ll coordinate directly with you to determine whether it’s best to reschedule or proceed once the area is clear.
Do you tarp plants or landscaping before applying chemicals?
No, we do not use tarps on plants due to the extreme South Texas heat.
Instead, we actively water all surrounding landscaping before, during, and after the roof cleaning process to prevent chemical absorption and heat damage. This method is safer and more effective for protecting your foliage in our climate.
How do you protect outdoor furniture or delicate fixtures near the roofline?
We cover or avoid spraying sensitive fixtures and recommend moving outdoor furniture when possible.
If furniture is left in place, we’ll do our best to avoid overspray and can lightly rinse affected areas afterward. Our technicians also tape over electrical outlets, light fixtures, and vents when needed.
Is there anything I should avoid doing before the roof is cleaned?
Yes, please avoid running sprinklers or scheduling other exterior work on the day of your roof cleaning.
Watering the landscape can interfere with our chemical application and runoff management. If you have other service providers scheduled, we recommend choosing a different day to prevent access conflicts.
Will roof cleaning affect nearby solar panels or electrical systems?
Roof cleaning will not damage properly installed solar panels or electrical systems.
We take care to avoid overspray and will not directly treat solar panels unless they’re being cleaned as part of a separate service. Outdoor outlets and fixtures are covered to ensure they stay dry and protected.
Do you clean roofs that have solar panels installed?
Yes, we clean roofs with solar panels in place and work carefully around them. If the panels cover large areas of the roof, we’ll clean around them as best as possible. If full cleaning beneath the panels is needed, we may discuss special access requirements.
How do you handle roofs with previously damaged or brittle areas?
We document any damage during our pre-clean inspection and adjust the cleaning approach accordingly.
We may avoid heavily deteriorated areas or pause service if cleaning could make the issue worse. Our technicians will always inform you before proceeding with any high-risk section.
Can you clean a roof while I’m not home but my pet is in the backyard?
We ask that all pets be kept indoors or away from the yard during your roof cleaning appointment.
The equipment, noise, and chemical use can startle or harm pets if they’re left outside. If no one is home to secure them, we may need to reschedule for safety reasons.
What if it rains right after you clean the roof—will that ruin the results?
A light rain won’t harm the cleaning results, but heavy rain within 30 minutes may reduce effectiveness.
We monitor weather conditions closely and may reschedule your appointment if a storm is forecasted. If any areas are impacted by rain, we’ll gladly return to re-treat them as part of our satisfaction guarantee.
Do you apply any protective treatments after the cleaning is done?
We do not apply additional roof sealants or coatings after cleaning.
Our soft wash system is designed to kill organic growth at the root, providing long-lasting results without the need for post-treatment. If you’re interested in a maintenance schedule, we’re happy to offer recommendations.
