Roof Washing in Slidell, LA
Those black streaks aren't dirt — they're living algae eating at your shingles. We soft wash it off safely and keep your roof looking new for years.
Black streaks are costing you more than looks
The dark streaks and green patches on your roof are algae, moss and mildew feeding on your shingles. Left alone, they hold moisture, lift granules and shorten the life of the roof you paid good money for.
Pressure washing a roof makes it worse — high pressure cracks shingles and forces water underneath. Our soft wash uses low pressure and the right cleaners to kill the growth at the root, so your roof comes back bright and stays clean far longer.

JoellRoof Washing questions, answered
Will soft washing damage my shingles?
No — that's the whole point of soft washing. We use low pressure and a cleaning solution instead of blasting, so shingles and granules stay put while the algae dies.
How long will my roof stay clean?
Because we kill the algae at the root instead of just rinsing it, a soft-washed roof usually stays clean far longer than a pressure-washed one — often a couple of years or more depending on shade and trees.
What are the black streaks on my roof?
That's a hardy algae that feeds on the limestone filler in shingles. It's extremely common on the humid Northshore and it spreads if you leave it.
Do you clean metal and tile roofs too?
Yes. We adjust the method to your roof type — shingle, metal, or tile — so it gets clean without damage.
How much does roof washing cost?
Every roof is different, so we quote after a quick look at the size, pitch and how much growth there is. Estimates are always free.
