Commercial Roofing in Roswell

Roswell's historic commercial square and the Holcomb Bridge corridor represent two distinct commercial building inventories - 19th-century masonry and early 20th-century brick alongside 1990s and 2000s suburban office and retail. Our routes cover both.

Roswell sits at the Chattahoochee River's southern bank, 20 miles north of downtown Atlanta on GA-400. The city's commercial real estate runs a wider age range than most Atlanta suburbs - the historic Roswell Square includes buildings from the 1840s and 1850s that have been continuously in commercial use, and the Holcomb Bridge Road corridor includes suburban office parks and retail centers from the 1988 to 2008 era. These are different roofing problems requiring different approaches.

Historic buildings in the Roswell Square area present the most challenging substrate conditions in the city's commercial inventory. Masonry parapet walls with no through-wall flashing, timber roof decks, steep-slope systems transitioning to flat sections, and Georgia Historic Preservation Division review requirements for changes visible from the street - these buildings require solutions that differ substantially from standard flat-roof TPO replacement. We assess these buildings honestly and will tell an owner when a historic preservation constraint limits the available warranty paths.

The Holcomb Bridge commercial corridor - Holcomb Bridge Road from GA-400 east to Alpharetta Highway, including the Crabapple Road intersection commercial cluster - was built in two waves: the late 1980s through mid-1990s suburban office and retail buildout, and the 2000s in-fill development. The 1990s buildings in this corridor are now running their first or second reroof cycles. The 2000s buildings are in mid-life to first-maintenance territory.

The commercial buildings on and around Roswell's historic square were built primarily between 1840 and 1920. Most are two to three-story brick masonry construction with mixed roof systems: original slate or clay tile on residential-pitch sections, flat or low-slope BUR systems on rear additions, and parapet walls without the through-wall flashing that modern codes require. Water entry in these buildings is often at the parapet wall-roof junction - a detail that original construction never addressed with a modern flashing assembly.

Roswell's historic district review process applies to exterior changes visible from the public right-of-way. Roof replacement work on historic square buildings typically falls outside direct historic review because the roof field is not visible from street level, but parapet work, coping replacement, and any above-parapet equipment additions require review coordination. We work with Roswell's Historic Preservation Commission staff on any scope element that touches a historic district-regulated exterior feature.

Timber roof decks in historic commercial buildings require a different fastener approach than steel or concrete decks. Standard screw-and-plate mechanical attachment patterns for TPO are designed for steel deck or concrete - timber deck TPO attachment requires longer fasteners at different patterns and periodic inspection to verify fastener withdrawal resistance. We specify timber-deck fastener patterns based on the deck species and condition documented during inspection.
