Roof Cleaning in Clay Township

Outside the platted strips, much of Clay Township is marsh, wet prairie and wildlife land, so on an open lot the slope that streaks first is the one the sun misses. On a channel-side house in Pearl Beach, that is the north slope facing Pointe Tremble Rd, which stays damp longest after dew and rain. The streaks are algae, commonly identified as Gloeocapsa magma, which is often said to feed on the limestone filler in asphalt shingles. Spores carried on the wind start new colonies. Where a lot does have a tree over the roof, moss can follow the algae and hold water against the shingle edges.

A roof drains through its gutters, and on a canal or channel lot a downspout on the water side can empty straight toward the seawall. Before treatment the downspouts are checked and turned away from the seawall, so what rinses off the shingles is kept out of the canal and the North Channel. Roofs on the older cottages near Pointe aux Tremble and along Anchor Bay Dr may carry many years of growth that has never been treated, and that takes a longer dwell before the streaks give way.

Cottage calendars shape the timing. Many homes here are seasonal, and a roof treated at closing has the off-season for rain and snowmelt to carry the dead growth away, since some staining keeps fading for weeks after the solution goes on. The owners then open a cottage whose streaks have had months to clear. Roof treatment starts at $450, and gutters cleaned on the same visit show as their own line, which also clears the grit and dead algae the rain washes down. Quotes are written, itemized and back within 24 hours, with no travel fee for the drive.

What Pressure and Scraping Do to Shingles

A pressure wand on asphalt shingles strips the protective granules, and the bare spots age quickly under sun and ice. It can also drive water under the tabs and loosen their edges, and a loosened tab can lift and tear in the next strong wind. Scraping moss with a stiff brush tears the shingle surface for the same reason. Warranties and cleaning instructions vary by manufacturer, so the shingle maker's guidance is worth reading before anyone climbs up with a wand.

When to Book Roof Cleaning in Clay Township

Roof treatment needs a dry day with no rain expected for several hours, so the solution can dwell. Fall works once the leaves are down, when the gutters can be cleared on the same visit and a cottage is about to close. Spring works too, before the June hatch fills the gutters, and the streaks keep fading into midsummer. Days that drop below freezing are skipped, because the solution needs time on a thawed roof.
