MODIFIED BITUMEN

COMMERCIAL MODIFIED BITUMEN ROOFING IN
SANDY SPRINGS

Bell Roofing upgrades low-slope buildings in Sandy Springs with commercial modified bitumen and asphalt roofs, designed for lasting performance. We also repair commercial asphalt shingle roofs in the Sandy Springs area on adjacent pitched surfaces to match the style of your building. Our crew handles every stage—from inspection through installation—so your next building renovation or flat roof replacement goes smoothly.

OUR BELL MODIFIED BITUMEN SYSTEMS

Our entry-level package installs two layers of GAF asphalt membrane that resist leaks on low-slope structures. The self-adhering sheets bond tightly without open flames. We cover your Sandy Springs commercial modified bitumen roof under a full 10-year labor and material warranty. GAF inspects each project to verify compliance with its industry standards.

Select this value-driven option for strong performance at a lower cost. The Bell Mod Bit 15 system applies a two-ply assembly of premium GAF asphalt sheets for dependable protection on flat roofs. We secure each layer for a flawless seal. You receive a 15-year warranty on workmanship and materials for your Sandy Springs area commercial modified bitumen roof project.

Choose this premium design for maximum durability. The three-ply structure features two reinforced base layers and a weatherproof asphalt cap sheet from GAF. Our skilled installers create a watertight barrier that stands up to ponding and UV exposure. We back this upgrade with a 20-year warranty, ensuring your Sandy Springs building’s commercial modified bitumen roof performs for decades.

WHY MODIFIED BITUMEN?

EFFECTIVELY
SHEDS WATER

1/12+
PITCH

Modified bitumen channels rainwater off low-slope structures quickly. When your commercial roof pitch reaches 1/12 or higher, this system prevents ponding and minimizes upkeep.

AFFORDABLE

50% COST
vs TPO

Modified bitumen runs at roughly half the cost per square foot of TPO membranes. Businesses benefit from reliable flat roof coverage without overspending.

REINFORCED
SYSTEM

2 or 3
LAYERS

Configure two or three membrane layers to match your budget and performance needs. Each assembly offers excellent tear resistance and temperature control. We back all options with 10-, 15-, or 20-year warranties on labor and materials.

SAFE

NO TORCH
NO SMELL

Our self-adhering GAF sheets install cleanly without open flames or odors. We maintain a safe worksite for uninterrupted operations.
