Common questions
Is it pressure washing?
No. High pressure on shingles can crack them, force water under flashing, and void manufacturer warranties. SmartWash applies a soft wash solution that dwells and breaks down algae without touching the roof with pressure equipment.
Will it void the roof warranty?
The process follows Asphalt Roofing Manufacturers Association (ARMA) guidelines, so it's built to align with what shingle manufacturers recommend.
What does it cost?
Most jobs run $500–$1,500, averaging around $750, priced by square footage, roof material, and access. Most homes are quoted the same day using satellite imagery — no ladder required for the estimate.
What's protected during the job?
Landscaping is soaked before, during, and after the clean by a ground crew member, while a second technician works the roof from ladders with stabilizers to minimize foot traffic on shingles.
