Roof Washing in Lima, OH
Those black streaks are algae, not dirt — a soft wash kills it at the root without lifting granules the way a pressure washer would.
Looking for roof washing in Lima, Ohio? Ohio Wash Boss brings the same soft-wash-first approach we use across Northwest Ohio to homes throughout Lima and the rest of Allen County. Here's what that looks like on a Lima property.
Lima is our home base, and it's where the bulk of our week is spent — from the older brick and clapboard homes near downtown to the newer vinyl-sided developments spreading out toward the edges of the city. Allen County's mix of mature tree canopy and clay-heavy soil means two things show up on almost every house we wash here: shaded-side algae that never quite dries out, and a fine layer of dust and pollen that settles into porous concrete and doesn't rinse off with a garden hose.
Older Lima neighborhoods with big shade trees tend to need roof and gutter attention more than newer construction — leaf litter builds up fast under a full canopy, and the black algae streaking on north-facing roofs is one of the most common calls we get from homeowners near the city's older tree-lined streets. Newer subdivisions on the outskirts see less of that, but they're not exempt from driveway oil staining and the general grime that builds up on any concrete exposed to Ohio winters and road salt.
Because we're local, we're not driving in from another county to get to a Lima job — which means scheduling is flexible and a callback for a spot we missed doesn't mean waiting another week. Whether it's a single house wash or a full exterior refresh before selling, we know which parts of town tend to need what.

How It Works

Roof inspection
We check shingle type and condition, and note any areas of heavier moss or algae buildup.
- 2
Soft-wash application
A low-pressure, algae-killing solution is applied across the roof surface — no high-pressure blasting of shingles.

Gentle rinse
The solution is rinsed at a pressure that clears algae without disturbing shingle granules.
