Casselberry, Florida · Soft-Wash Roof Cleaning
Your Roof Was Last Redone Sometime Between the Ford Administration and the First Bush.
Casselberry Roof Cleaning soft-washes shingle and tile roofs across Casselberry, FL — Deer Run, Sausalito Shores, Carriage Hill, Wyndham Woods, and the neighborhoods around Lake Kathryn and Lake Howell. Much of the city's housing stock dates to Casselberry's 1950s–80s growth boom, so most roofs here are on a second or third re-roof, giving black algae streaking decades, not years, to take hold.

Why Casselberry Specifically
More Lakes, More Shade, More Time for Algae to Work
30+ Lakes in 7.5 Sq. Mi.
Casselberry packs more than thirty lakes and ponds — including Lake Howell, the Triplet Chain of Lakes, and Lake Kathryn — into one of the smallest footprints in Seminole County. That much open water keeps humidity and dew-point duration higher near shoreline neighborhoods, exactly what black-streak algae needs to colonize a roof quickly.
Mature Oak Canopy
Casselberry's own tree specifications list laurel oak, live oak and bald cypress as common in established neighborhoods. That canopy shades roof slopes and drops leaf litter and debris — both of which accelerate moss growth on a shingle roof.
Older Housing Stock
A large share of Casselberry's homes date to the city's 1950–1980 growth boom. Subdivisions like Carriage Hill (1967–71) and Lake Kathryn Park (1946–68) are old enough to be on a second or third re-roof, past the point a shingle's factory algae-resistance was designed to last.

FAQ
Common Questions About Roof Algae & Moss
What causes black streaks on a roof?
On most Casselberry shingle roofs, those streaks are Gloeocapsa magma — a blue-green algae that feeds on the limestone filler in asphalt shingles and produces a dark, UV-resistant pigment as it spreads. It travels by airborne spores, which is why it usually shows up first on a roof's shaded, north-facing slope.
Why is my roof turning black?
Same organism, different phrasing of the same question. Casselberry packs more than 30 lakes and ponds into 7.5 square miles, and the ambient humidity that comes off that much open water — combined with mature oak canopy shading many of the city's older roofs — is close to ideal growing conditions for it.
Does moss damage a roof?
Yes, more than algae alone does. Moss holds moisture directly against the shingle or tile surface and works its rhizoids under the tabs, which lifts granules and edges over time. It shows up on the same shaded, tree-covered slopes where algae already grows — common across Casselberry's older, well-treed subdivisions.
How often should you clean your roof?
Most Central Florida homes benefit from a soft wash every 2 to 4 years, sooner in shaded, lake-adjacent, or heavy-canopy locations where algae and moss return faster. A roof already on its second or third re-roof — common across Casselberry's older housing stock — is also more likely to need low-pressure methods to avoid stripping brittle, aged granules.
How much does gutter cleaning cost?
We don't have Casselberry-specific gutter pricing to publish here [NEED: gutter-cleaning price sheet]. What we offer under gutter brightening is the exterior cosmetic cleaning that follows a roof soft wash, not full interior debris removal — ask us for a number specific to your home.
