Saves on repairs

Prevention is cheaper than replacement.

Curb appeal

A clean roof increases property value and visual appeal

Soft wash vs. pressure wash

Standard pressure washing is designed for concrete and hard surfaces, not flat roofs. Our soft-wash method uses low-pressure application with professional-grade cleaning agents to deliver a deeper, safer clean.

Our soft wash method

  • Safe for TPO, EPDM, modified bitumen, and coated roofs
  • Biodegradable solution kills moss, algae, and bacteria at the root
  • No risk of membrane puncture or seam separation
  • Results last 2-3x longer than pressure washing alone

Pressure wash risks

  • Can tear single-ply membranes and lift seam adhesive
  • Forces water under flashing and into insulation
  • Strips protective granules and coatings
  • Only removes surface growth - regrowth within months

Our Cleaning Process

Safe, Thorough, and Non-Destructive

1

Roof Inspection

  • We assess the type of growth, debris, and overall roof condition.
  • Identify vulnerable areas. Seams, drains, and flashing.
2

Low-Pressure Soft Wash

  • Biodegradable cleaning solution applied to break down moss, algae, and lichen.
  • Gentle rinse. No high-pressure that could damage the membrane.
3

Drainage & Detail Work

  • Gutters, scuppers, and drains cleared of all debris.
  • Flashing and edge details hand-cleaned for a thorough finish.
4

Final Review

  • Walk-through inspection to confirm a complete, damage-free clean.
  • Photo report and maintenance recommendations provided.

Does your roof need cleaning?

Flat roofs collect moisture and organic debris faster than pitched roofs. If you notice any of these warning signs, your roof is overdue for professional cleaning:

  • Dark streaks or black staining on the roof surface
  • Visible moss, algae, or lichen growth
  • Standing water that drains slower than usual
  • Clogged or overflowing gutters and scuppers
  • Granule buildup in downspouts or at the roof edge
  • Musty odor near ceiling areas or in the attic
