Commercial Roof Washing in Baltimore
In-House Crews, Soft Wash Method, & a Commercial Grade Guarantee
Biological growth, debris, and organic staining on a commercial roof aren’t cosmetic problems. They trap moisture against roofing surfaces, block drainage on flat and low-slope systems, and accelerate the kind of material breakdown that turns a maintenance issue into a capital expense. Chesapeake Property Services has been handling commercial roof washing in Baltimore since 2004. It’s a family-owned operation serving Baltimore City, the Inner Harbor, and the surrounding counties with the same in-house crew on every job.
Baltimore’s hot, humid summers and dense commercial building stock create conditions where algae, moss, and lichen accumulate faster than most facility managers expect. The right response isn’t high pressure and a quick pass. It’s the right method, the right cleaning chemistry, and a crew trained to work safely around commercial buildings of every size and configuration.

What Commercial Roof Washing Actually Fixes
Biological growth on a commercial roof is an active problem, not a cosmetic one. Algae retains moisture against roofing surfaces and accelerates deterioration, while moss and lichen damage materials as they grow. Moss lifts and separates shingles; lichen embeds root-like structures that gradually crack the surface beneath. For the flat and low-slope roofs common in Baltimore’s office and retail buildings, debris accumulation blocks drainage and leads to ponding water. Pairing routine roof washing with commercial gutter cleaning is one of the more practical ways to keep water moving off your building the way it should.
Baltimore’s humid summers and shaded urban rooflines create above-average conditions for algae and moss growth. Left unaddressed, that organic growth traps heat against the roofing membrane, adding to interior cooling costs and contributing to wear on the material below.
Some of the most common issues commercial roof washing addresses are:
- Black streaks and dark staining from algae growth
- Green or gray moss patches on shingles or membrane surfaces
- Lichen colonies embedded in roofing material
- Debris buildup blocking drainage points on flat roofs
- Mildew growth in shaded or poorly ventilated roof sections
- General weathering stains from environmental exposure
Chesapeake Property Services focuses on the details others miss, clearing every corner and drainage point so your roof performs the way it should. Our technicians work efficiently and keep the process seamless for your staff and tenants.
