Roof maintenance isn't glamorous, but it's the difference between a roof that reaches its full lifespan and one that fails early.
Dark streaks and roof algae
Those black streaks on a roof are usually algae feeding on limestone filler in the shingles. It is mostly cosmetic, but the growth holds moisture against the roof, and a gentle professional cleaning plus zinc or copper strips keeps it from coming back.
Preventing algae and streaking long-term
Zinc or copper strips near the ridge release trace metals when it rains that inhibit algae growth down the roof. On new roofs in humid climates, algae-resistant shingles are worth requesting up front.
Moss, lichen, and shaded roofs
On heavily shaded roofs, moss and lichen hold moisture against the shingles and work their roots under them. Trimming back overhanging branches to let sun and air in is the best long-term defense against organic growth.
Asphalt shingles: the default for a reason
Architectural asphalt shingles remain the most popular roofing choice because they balance cost, durability, and curb appeal. Modern laminated shingles carry 25-to-50-year warranties and hold up well when installed with proper ventilation and quality underlayment.
Trees, limbs, and your roof
Overhanging limbs scrape shingles, drop debris into valleys, and become projectiles in a storm. Keeping branches trimmed back from the roof is simple protection against both slow wear and sudden damage.
Frequently Asked Questions
Does shingle color matter?
Yes — lighter shingles reflect more heat and keep attics cooler, and color strongly affects curb appeal and resale, so it's worth coordinating with your brick and trim.
When should I get my roof inspected?
At least once a year, and again after any major storm. Catching damage early keeps a small repair from becoming an interior leak, and creates a dated record of your roof's condition.
What's the best roofing material?
There's no single best material: it depends on your budget, roof slope, climate, and how long you'll stay in the home. Asphalt wins on value, metal on longevity, and tile or slate on lifespan and looks.
