Apex Roofing Solutions in Atlanta, GA

Left untreated, algae degrades shingle granules and creates microscopic surface texture that retains even more moisture, eventually leading to moss colonization that physically lifts shingle tabs with root structures. In Marietta and Cobb County, where the housing stock spans from 1950s brick ranches to 1990s Williamsburg colonials, we encounter a wide range of underlayment conditions — many homes from the 1980s still have the original 15-lb felt under their second or third shingle layer, and when a fallen limb punctures through, the compromised felt allows water to wick laterally to areas far from the visible impact point. Our repairs in Atlanta always include a decking moisture assessment: we probe for soft spots in a radius around any visible damage, because wet OSB can show no exterior symptoms while actively delaminating underneath.

Chimney flashing repair is also a significant part of our Atlanta workload — the combination of Atlanta's temperature swings and its clay-heavy soil causes chimney foundations to move, which breaks the bond between step flashing and masonry even on relatively new installations.

We coordinate with certified arborists to trim limbs to code clearance — at least six feet from the roof surface — before replacement begins, and we include debris-removal coordination in every project scope. For older homes in Decatur and the Candler Park neighborhood, replacement projects frequently uncover multiple layers of shingles — Georgia code allows up to two layers, and we always remove all existing material rather than overlaying, because shingling over an existing layer traps moisture under the new system and voids the manufacturer warranty on the new shingles.

Removing multiple layers also allows us to inspect and repair the decking, which in Atlanta's humidity is often the most important part of the project: OSB installed in the 1990s under failing shingles is commonly found with black staining and edge delamination that would compromise the new installation if left in place. For Marietta and Kennesaw homes where asphalt shingle is the standard, we install GAF's WeatherBlocker or equivalent starter strip at all eaves and rakes before laying field shingles — this adhesive-edge strip is the most important defense against wind-driven rain infiltration under the first course, which is the leading cause of soffit and fascia rot in Atlanta's wet winters.

This debris load has two consequences: overflow at blocked downspout openings that saturates the soil against the foundation, and standing water in partially blocked sections that accelerates corrosion in older aluminum gutters and provides breeding habitat for mosquitoes. In Decatur and Avondale Estates, where many homes have seamless aluminum gutters from installations in the 1990s and 2000s, the primary failure mode is joint separation at end caps and internal miters — the silicone sealant used at these joints loses elasticity in 8 to 12 years under Atlanta's humidity, and once it separates, the joint leaks with every rainfall, directing water behind the fascia and into the top of the exterior wall. Our Marietta repairs frequently address a different issue: homes on sloping lots in Cherokee and Cobb County often have gutter runs that are too long for a single downspout, and the far end of the run backs up during heavy Atlanta downpours.

We add mid-run downspout outlets and connect them to underground drainage lines that route water to the street or a designated drainage swale — a permanent solution rather than a repeated repair cycle.
