Snellville Roofing Contractor: Local, Accountable Roof Care for 20+ Years

Hail bruises and fractures asphalt shingles and knocks off the granules that protect them from UV. Straight-line winds can break the seal strips, crease shingle tabs or tear shingles off entirely. Either way, water can get into the decking and attic.

March through May is severe-weather season in Gwinnett, DeKalb and Rockdale, and repeated spring hail days have set off waves of insurance claims across the county. Storm remnants like Zeta also bring sustained winds that lift shingles on older roofs where the seal strips have dried out. Damage often isn't visible from the yard, and many policies now carry percentage wind/hail deductibles, so careful documentation matters. Storm chasers show up the week after, which makes it even more important to have a local roofer you can hold accountable.

• Granules piling up in gutters or at downspout outlets
• Dark, circular bruises or dents on shingles
• Shingles missing, creased or lifted after high winds
• Dented gutters, vents or AC fins
• New ceiling stains after a storm

Hail claims cluster in Snellville, Grayson and Loganville along the Hwy 78 corridor, where spring storm cells tend to track. Two-story traditionals in Centerville and Brookwood take wind hits on their exposed upper ridges.

Our fix: We tarp right away if needed, photograph and measure the damage, meet your adjuster on request, and repair or replace to code and manufacturer spec.

Asphalt shingles break down as the asphalt dries out and the granules wear away. Near the end of their life they curl, crack and blister, and they stop shedding water well. Repairs eventually stop holding because the surrounding shingles are just as worn out.

Subdivisions built from the late 1990s to the mid-2000s mostly went up with builder-grade architectural shingles, and those are now 20–25 years old. Snellville's hot attics and strong summer UV speed up aging, especially on south and west slopes. Many older homes also have too little attic ventilation, which traps heat under the deck and shortens shingle life even more. The result is whole neighborhoods reaching replacement age at the same time.

• Curled, cupped or clawed shingle edges
• Bald patches where granules are gone
• Cracked or brittle tabs
• Shingles from the original build
• Rising summer cooling bills

We see this a lot in Collins Hill and Five Forks in Lawrenceville, and in Snellville subdivisions from the late 1990s and early 2000s. South- and west-facing slopes usually fail years before the north side does.

Our fix: We assess remaining life honestly. If replacement makes sense, we install new shingles with proper underlayment, drip edge and balanced ventilation.

Flashing is the metal that seals the joints where a roof meets a wall, chimney, skylight or vent. Pipe boots are the rubber collars around plumbing vents. When either fails, water runs along the decking and framing, often well away from where the stain shows up.

Rubber pipe boot collars crack in Georgia's UV long before the shingles around them wear out. Step flashing on homes from the 1980s and 1990s was often installed with caulk instead of proper counterflashing, and that caulk fails after years of hot-and-humid cycles. With rain falling year-round, a slow drip around a chimney or skylight can rot decking for years before anyone sees a ceiling stain.

• Brown ceiling stains near chimneys or bathrooms
• Cracked rubber around plumbing vents
• Rusty or lifted flashing at walls
• Damp attic sheathing or insulation
• Soft spots when walking near penetrations

This is common on brick-front homes in Snellville and Lilburn's Mountain Park, where step flashing runs along tall sidewalls. Skylights in 1990s homes in Brookwood and Five Forks are another frequent source.

Our fix: We replace failed boots and flashing with proper step and counterflashing, cut out any soft decking, and reseal so the spot doesn't leak again.

Decking is the plywood or OSB sheathing the shingles are nailed to. Long-running small leaks soften and delaminate it. A rotted deck won't hold nails, it sags, and over time it can damage rafters and invite mold into the attic.

Snellville's humidity keeps wood damp longer, and frequent rain means a leak rarely gets a chance to dry out. Older OSB in builder-grade construction swells when it gets wet. Slow leaks at chimneys, skylights and pipe boots can go unnoticed for years, especially in attics nobody checks. We often find it during tear-off on homes that never had a visible interior leak.

• Sagging or wavy roof lines
• Spongy feel underfoot on the roof
• Dark or stained sheathing in the attic
• Musty attic odor
• Shingle nails backing out

It's common on 1970s–80s homes in Stone Mountain Village, Tucker and Lilburn, and around skylights and chimneys in Snellville split-levels. Homes under heavy pine canopy that stay shaded and damp are especially prone.

Our fix: We replace the damaged sheathing during repair or tear-off and price it per sheet up front, so you know the cost before any surprises.

Valleys channel a lot of water off the roof. When leaves and pine straw pile up there or in the gutters, water backs up under the shingles and spills over onto the fascia and soffit, rotting the trim and splashing against your foundation.

Thick oak, pine and sweetgum canopy covers much of eastern Gwinnett. Leaves drop in fall and pine straw comes down most of the year. Red Piedmont clay drains poorly, so overflow sits against the foundation and stains siding orange. Complex roofs with lots of valleys catch even more debris.

• Water sheeting over gutter edges in rain
• Peeling paint or soft fascia boards
• Debris piled in roof valleys
• Orange clay splash on siding
• Sagging gutter runs

We see this all over wooded lots in Grayson, Bay Creek and Mountain Park. Luxury homes in Hamilton Mill and Suwanee with many valleys clog fastest under mature trees.

Our fix: We clear valleys, repair or replace rotted fascia and soffit, correct valley flashing, and recommend a maintenance schedule that fits how much tree cover you have.

Low-slope roofs need membrane systems, not shingles. When water sits more than about 48 hours, it breaks down the membrane, finds seams, and adds weight to the structure.

Many 1960s–70s ranches have carports and additions that were framed nearly flat and finished with roll roofing or shingles that were never meant for that pitch. Downtown commercial blocks in Lawrenceville, Norcross and Conyers have aging membrane roofs. Heavy summer downpours overwhelm drains that are clogged with debris.

• Standing water a day or two after rain
• Blistered or cracked roll roofing
• Open seams on membrane
• Interior leaks under additions
• Algae rings where water sits

This shows up on carports and additions in Tucker, Clarkston and Stone Mountain, and on older commercial buildings in Historic Norcross and Olde Town Conyers.

Our fix: We correct drainage, build tapered slope where needed, and install a proper low-slope membrane system rated for ponding and Georgia heat.

The black streaks are Gloeocapsa magma, an airborne algae that feeds on the limestone filler in shingles. Moss and lichen grow on shaded slopes and hold moisture against the roof surface.

Long humid stretches plus heavy tree shade create ideal growing conditions, especially on north-facing slopes. Algae is mostly cosmetic, but moss lifts shingle edges and holds water, which speeds up wear.

• Black or dark streaks down slopes
• Green moss clumps at shingle edges
• Gray-green lichen spots
• Darker north-facing slopes

It's common across shaded lots in Snellville, Lilburn and Tucker. HOAs in Grayson and Suwanee sometimes send violation letters over badly stained roofs.

Our fix: We do soft-wash treatment (no pressure washing), remove moss carefully, and offer algae-resistant shingles at your next replacement.
