Asphalt Shingle Roofing in Winston-Salem

Why do shingle roofs get black streaks in the Piedmont?

The streaks are often algae, a type called Gloeocapsa magma, which feeds on the limestone filler in asphalt shingles and thrives in humid weather. Moss is a separate problem because it lifts shingle edges and holds moisture. Soft washing, a low-pressure method, is the cleaning approach sources recommend.

The stains show first on shaded slopes where the roof stays damp, and freeze-thaw winters make moss damage worse. Contractor guidance from around the Piedmont recommends soft washing over pressure washing, because high pressure can strip granules and push water under the shingles.

The moss and algae treatment page covers cleaning in depth, and the Piedmont moss guide goes further.

How do I know if my shingles can be repaired or need replacing?

Local damage, such as a few lifted or missing shingles, can usually be repaired. Widespread curling, cracking and granule loss across a whole slope points toward replacement. A roofer's inspection settles it, and nothing on this site can tell you a roof is sound or failing.

Roofers look at how widespread the problem is, how the shingles feel underfoot or in hand, and whether the deck is sound. Surface staining alone is cosmetic, but staining paired with lifted edges deserves a closer look.

If the roof is older and repairs keep adding up, see the roof replacement page for the permit and cost picture.

What do shingle roofs need in a humid summer?

They need airflow, clear gutters and a clean surface. July is the hottest and muggiest month in Winston-Salem, with an average high of 87 F, so attic heat and trapped moisture matter for shingle life, and shaded roofs stay damp and grow algae.

Check gutters for shingle grit, trim branches that overhang the roof, and pay attention to attic conditions. The attic ventilation page explains what roofers look at in the attic.

Ask your roofer what ventilation your particular roof has and whether anything about it concerns them. The answer depends on the house.

What does a shingle roof job look like from the driveway?

Expect a crew to set up ladders and a dumpster or tarps, strip the old covering if the job calls for it, repair the deck, then lay new shingles from the eave up to the ridge. Roofers schedule around weather, and the permit and the on-site quote come first.

Tear-off is the loudest part. Old shingles and nails come down in large quantities, which is why you should move cars, children and pets out of the work zone. Tarps over shrubs and a magnet sweep of the lawn afterward are worth asking about before the job begins.

The new covering goes down in rows, each one overlapping the one below so that water sheds downward. Ridge caps finish the top, and flashing is renewed or checked around chimneys, walls, and vent pipes. In an older house, this is also when hidden problems turn up, like soft decking under a long-running leak.

If the roof has had a leak, ask the roofer to show you photos of what they found. It is the best way to understand what the money paid for.

Which houses in Winston-Salem usually wear shingles?

Most of the city's housing stock does. Property data shows the median home was built in 1977 and counts 12,194 homes from the 1960s, 15,546 from the 1970s and 18,059 from the 1980s. Houses from those decades are mostly roofed in asphalt shingle, which is why the product dominates local roofing work.

Ardmore's streets, the neighborhoods around Hanes Mall, which opened in 1975 beside I-40, and the subdivisions that grew through the 1980s all fit that pattern. Houses in the historic districts are a separate case, because roof changes there go through the Historic Resources Commission, so ask the roofer to confirm what your house has and what review applies.

Newer building is part of the picture too, since property data counts 12,458 homes from the 2010s. Whatever the decade, the first step is the same: a roofer looks at the covering that is actually on the house and tells you what it is.
