5 Common Roof Problems Cape Cod, MA Homeowners Should Check For After Summer (Roof Cleaning Guide)

5 Common Roof Problems Cape Cod Homeowners Should Check for After Summer

When summer wraps up on Cape Cod, heat, humidity, and salty breezes can leave silent damage across your shingles. If you've noticed stains or streaks, it's a smart time to schedule roof cleaning in Cape Cod, MA with a trusted local pro like A To Z Softwash so your roof is ready for fall storms and winter winds.

Why Late Summer Is Tough On Cape Cod Roofs

From Hyannis to Falmouth and up through Sandwich and Barnstable, our weather brings warm sun, sticky humidity, ocean salt, and sudden thunderstorms. That mix encourages organic growth, loosens protective granules, and can corrode metal around vents and flashing. A careful check now can prevent leaks, wood rot, and costly surprises later.

Cape Cod's sea breeze can leave a thin salt film on roofs after long stretches of onshore wind. Removing that film before fall rains helps reduce staining and slows corrosion around flashing and fasteners.

1) Black Streaks From Algae

What It Looks Like

Dark, drip-like lines running down asphalt shingles are usually blue-green algae. It thrives in our humid summers and often appears first on north-facing slopes or areas shaded by pines and oaks.

Why It Matters

Algae stains absorb heat and can shorten the life of shingles over time. Don't ignore streaks that seem cosmetic; they signal a living growth that spreads with every rain. A professional soft wash removes the stains and helps protect your roof's reflective qualities.

2) Moss And Lichen In Shady Areas

What It Looks Like

Think of spongy green clumps or flat, crusty circles along the edges of shingles, dormers, and valleys. You'll see this more in wooded parts of Mashpee, Osterville, and Bourne, where shade lingers after afternoon showers.

Why It Matters

Moss and lichen trap moisture against the roof surface. Over time, that moisture can creep under shingles, lifting them and weakening the adhesive strip. Never allow high-pressure water on shingles because it can tear granules and force water underneath. Soft washing targets growth without stripping away protection.

3) UV Wear And Granule Loss

What It Looks Like

After sunny spells, check for bald patches or excessive granules in your gutters and at downspout outlets. Granule loss shows up as lighter spots where the shingle surface looks smooth instead of textured.

Why It Matters

Granules shield shingles from sunlight. When they wear away, the asphalt base ages faster and can crack. Gentle, professional cleaning helps maintain the top layer rather than blasting it away, which keeps your warranty and roof life in better shape.

4) Salt Air Corrosion Around Flashing

What It Looks Like

Along roof penetrations like chimneys, skylights, and vents, you may see rust stains or chalky residue. Homes near the shoreline or open bays often show this sooner because salt settles on metal and fasteners.

Why It Matters

Rust can widen seams and create leak paths long before you notice a drip inside. Soft washing removes salt deposits so metal lasts longer, and a professional can spot cracked boots or failing sealant during the visit. Salt plus standing moisture speeds up corrosion even when shingles look fine from the street.

5) Clogged Or Misaligned Gutters At The Roof Edge

What It Looks Like

Look for water stains on fascia boards, peeling paint near gutter brackets, or dirt lines where water has run over the edge. Late-summer pine needles and early fall leaves can sit in gutters for weeks, especially under tall trees in Dennis and Yarmouth.

Why It Matters

Overflowing gutters push water back toward the roof edge and under shingles, which can rot sheathing and invite pests. A complete soft wash service can clear roof-shed debris from trouble spots and keep grime from feeding new growth along the eaves.

How Professional Roof Cleaning Protects Your Home

Safe soft washing removes organic growth, salt film, and grime without damaging shingles. Done by an experienced team, it also doubles as a top-side check that can flag early issues before they turn into leaks.

  • Soft wash cleaning breaks the growth cycle of algae, moss, and lichen.
  • Rinsing away salt residue helps preserve flashing, vents, and fasteners.
  • Trained eyes catch lifted shingles, cracked boots, and blocked valleys.
