Flat & Low-Slope Roof Cleaning
Flat and low-slope roofs — common on Eichler homes across the Peninsula — collect debris and standing water differently, and need cleaning that respects the membrane.
Why flat roofs are different
Flat and low-slope roofs don't shed water the way a pitched roof does. Debris collects in low points and clogged drains lead to standing water — a common issue on the Peninsula's many Eichler-style homes.
Our process
We clear debris from drains and low points first, then clean the surface at low pressure with a membrane-safe solution. Nothing abrasive that could compromise the roofing material.
What we watch for
Standing water after 48 hours of dry weather, debris blocking drains, and visible membrane wear we should flag before it becomes a leak.
Frequently asked
Can you check my drains while you're up there?
