ARMA-approved roof cleaning - 3-year warranty.
ARMA-approved zero-pressure roof cleaning. Asphalt Roofing Manufacturers Association-endorsed method using sodium-hypochlorite-based solution at zero PSI. Kills algae, moss, lichen, and gloeocapsa magma at the spore level. No mechanical contact with shingles - no granule loss, no warranty void.
Asphalt shingle roofs, metal roofs, tile roofs. Residential and small commercial. Most effective on roofs with visible black streaks, green moss, or lichen patches.
Every 24-36 months for most Metro Atlanta roofs. Our 3-year warranty covers re-growth within that window.
**3-year warranty against algae and moss re-growth.** If algae streaks or moss patches return within 36 months on a treated roof, we re-treat at no charge.
The black streaks running down an Atlanta roof are not dirt and they will not wash off. They are gloeocapsa magma, a hardy algae that feeds on the limestone filler in asphalt shingles and spreads by airborne spores, which is why it tends to appear on one roof and then the whole street. Alongside it you get moss holding moisture against the shingle and lichen rooting into the surface.
Left alone it is cosmetic first and structural later. The algae holds moisture on the shingle, and moisture on a shingle shortens its life. Cleaning a roof is cheaper than the alternative by an order of magnitude.
High-pressure roof cleaning voids most shingle manufacturer warranties, and for good reason: the force strips the protective granules off the shingle surface. The roof looks clean for a season and ages faster for the rest of its life.
Sunshine uses the ARMA-approved method instead, which is zero pressure. The Asphalt Roofing Manufacturers Association endorses soft-wash chemistry precisely because nothing makes mechanical contact with the shingle. If a company is quoting you a pressure wash for your roof, ask what happens to your warranty.
A pressure washer removes the algae you can see. The spore base stays, which is why a pressure-washed roof streaks again within a season. Soft wash chemistry kills the organism at the spore level, so regrowth starts from nothing rather than from an established colony. That difference is the whole reason our warranty runs three years instead of three months.
There is no flat rate. Price moves with the size and pitch of the roof, how much access the crew needs, and how heavy the algae, moss or lichen growth has become. A roof with early streaking and a roof carrying ten years of moss are different jobs. Sunshine scopes the number from a free quote rather than publishing a range that changes the moment someone sees the roof.
Landscaping under the roofline is tarped before anything is applied, and the area is pre-rinsed and re-rinsed as needed. The solution is biodegradable. Nothing about the method requires anyone to walk the roof more than necessary, which matters on older shingles.
The most common roof in Metro Atlanta and the one gloeocapsa magma feeds on, because it eats the limestone filler in the shingle. The ARMA-approved method exists for this roof: zero pressure, no granule loss, no warranty void. Explainer: what ARMA-approved roof cleaning means.
The same zero-pressure method works on metal. Nothing makes mechanical contact with the panel or its coating; the solution does the work and is rinsed.
Tile takes the same zero-pressure treatment, residential and small commercial. Nothing about the method requires anyone to walk the roof more than necessary, which matters on tile as much as on older shingles.
Every 24 to 36 months for most Metro Atlanta roofs, sooner under dense oak canopy. Timing guide: when should I have my roof soft-washed in Atlanta? The streaks themselves: why does my roof have black streaks?
Not when ARMA-approved methodology is used. The Asphalt Roofing Manufacturers Association explicitly endorses zero-pressure soft-wash chemistry as the safe method for cleaning shingle roofs. High-pressure roof cleaning DOES void most shingle warranties - we don't use that method.
24-36 months typical, covered by our 3-year warranty. The chemistry kills algae and moss at the spore level rather than just removing visible growth, which is why re-growth is delayed significantly compared to plain water washing.
Gloeocapsa magma - a hardy algae that feeds on limestone filler in asphalt shingles. It spreads via airborne spores from neighbor roofs and is purely cosmetic at first but accelerates shingle degradation over time. ARMA-approved soft wash kills it. High-pressure washing just rinses the visible algae and leaves the spore base intact.
Yes. We tarp any landscaping below the roof, pre-rinse and re-rinse as needed, and use biodegradable solution. The roof structure itself is protected by ARMA-approved zero-pressure methodology.
Soft wash roof cleaning removes algae, moss and lichen using cleaning solution at zero PSI instead of a pressure washer. There is no mechanical contact with the shingles, so nothing strips the granules off the surface. It is the method the Asphalt Roofing Manufacturers Association endorses for cleaning a shingle roof, and it is what Sunshine uses on every roof.
There is no flat rate that holds up. Price moves with the size and pitch of the roof, how much access the crew needs, and how heavy the algae, moss or lichen growth is. Sunshine scopes the final number from a free quote rather than quoting a range that changes once someone sees the roof.
Roof cleaning should never be pressure washing. High-pressure roof cleaning voids most shingle warranties because it drives granules off the shingle surface. Sunshine uses ARMA-approved zero-pressure soft washing, which kills algae and moss at the spore level without touching the shingle mechanically. Pressure washing has its place on concrete and hardscape, not on a roof.
Every 24 to 36 months for most metro Atlanta roofs. Sunshine's 3-year warranty covers algae and moss re-growth inside that window, so the warranty and the recommended interval line up on purpose.
Yes. The same zero-pressure method works on asphalt shingle, metal and tile roofs, residential and small commercial. It is most effective on roofs showing visible black streaks, green moss or lichen patches.
No. Landscaping below the roof is tarped, and the area is pre-rinsed and re-rinsed as needed. The solution is biodegradable.
Yes. Sunshine backs every roof cleaning with a 3-year warranty against algae and moss re-growth. If streaks or moss patches come back within 36 months on a treated roof, we re-treat at no charge.
