The specialty most commercial roofs are built on — Mason Exteriors installs and repairs flat and low-slope systems across Jefferson, Cumming, and North Georgia.
Most commercial buildings have flat or low-slope roofs, and those roofs need a completely different approach than a steep residential roof. Mason Exteriors specializes in flat and low-slope roofing across Jefferson, Cumming, and North Georgia — the core of our commercial work.
As experienced flat-roof installers, we install and repair the systems built for flat roofs: TPO and EPDM single-ply membranes and modified bitumen. These systems are engineered for standing water, foot traffic, and rooftop equipment — the realities of a commercial roof.
We're, licensed, fully insured, and known for fair, competitive pricing. Whether it's a new flat roof, a replacement, or a repair, we handle it as the specialty it is.
The membranes and systems we specialize in.
Reflective, energy-efficient membrane popular on commercial roofs.
Durable rubber membrane trusted for flat and low-slope roofs.
Tough, multi-ply asphalt system for demanding flat roofs.
Built for standing water, foot traffic & rooftop equipment.
A flat roof isn't truly flat — it's designed with a slight slope so water drains slowly toward drains. That slow drainage means the system has to be genuinely watertight, not just water-shedding, and every seam and detail has to be right. It's a different craft than shingle roofing.
That's why flat roofing calls for a specialist and the right materials. Single-ply membranes and modified bitumen are purpose-built for these roofs, and as experienced flat-roof installers, we install and repair them the way they're meant to be done.
From a new commercial flat roof to a targeted repair, we bring the specialized experience these roofs demand.
Every flat and low-slope project is handled by our experienced flat-roof team.

It depends on your building, budget, and how the roof is used. TPO is reflective and energy-efficient, EPDM is durable and proven, and modified bitumen is tough and multi-ply. We’ll recommend the right one.
Yes — new installation, replacement, and repair of flat and low-slope roofs are all core parts of what we do.
Because they depend on slow drainage and a genuinely watertight, sealed system. The seams, flashing, and details all have to be right, which takes flat-roofing experience and the correct materials.
Mostly, but not only — homes with flat sections, additions, or porches use these systems too. We handle both residential flat sections and full commercial flat roofs.
