Bitumen Roofing
MULTI-LAYER FLAT ROOFING BUILT FOR DURABILITY ACROSS GEORGIA, ALABAMA & TENNESSEE
- TOUGH. WATERTIGHT. BUILT LAYER BY LAYER.
WHEN YOUR FLAT ROOF NEEDS MORE THAN A SINGLE LAYER.
Single ply membranes work well in many situations. But some commercial roofs need something tougher, a system with multiple reinforced layers, stronger puncture resistance, and better performance under regular foot traffic. That is where modified bitumen earns its place. An asphalt based system installed in multiple layers with redundancy built in from the start, we install torch applied and cold applied modified bitumen systems for commercial properties across Georgia, Alabama, and Tennessee.

New Modified Bitumen Installation
We install torch-applied and cold-applied modified bitumen systems on new and existing commercial buildings. Every installation starts with proper substrate preparation and builds up layer by layer, with the base sheet, reinforcing ply, and cap sheet installed to manufacturer specifications.
Modified Bitumen Roof Replacement
When an existing modified bitumen system has worn out or sustained damage beyond repair, we manage the full replacement, removing the old system, inspecting and repairing the deck as needed, and installing a new multi-layer system built to current specifications.
Modified Bitumen Roof Repair
Blisters, splits, cap sheet wear-through, flashing failures, and membrane lifting are the most common repair issues on modified bitumen roofs. We locate the source of the problem, cut out the damaged section, and install a properly adhered repair patch that integrates with the existing system.
Flashing & Penetration Repair
Transitions at parapet walls, drains, HVAC curbs, and pipe penetrations are where most modified bitumen leaks originate. We remove failing flashing, clean and prime the substrate, and install properly adhered and sealed flashing details that hold up under repeated thermal movement.
Blister & Delamination Repair
Blisters form when moisture gets trapped between layers. Left unaddressed, they grow and eventually split open. We cut and dry blistered areas, apply compatible adhesive, and re-bond the membrane to eliminate the void before it fails completely.
Modified Bitumen Maintenance & Inspection Programs
Annual inspections extend the life of a modified bitumen system and catch early signs of wear, including cap sheet granule loss, flashing separation, and drain performance issues before they turn into water intrusion problems. We inspect, document, and address what needs attention.
WHY BUSINESSES CHOOSE Kross Roofing
MULTI-LAYER MEANS BUILT-IN REDUNDANCY
Modified bitumen is not a single membrane between your building and the weather. It is a system with multiple reinforced layers working together. If the cap sheet takes damage, the layers underneath are still protecting your building.
HANDLES FOOT TRAFFIC BETTER THAN SINGLE PLY
Rooftop equipment access is a reality for most commercial buildings. HVAC crews, technicians, and maintenance staff walk flat roofs regularly. Modified bitumen handles that traffic without the puncture risk that comes with thinner single ply membranes.
TORCH APPLICATION DONE BY TRAINED HANDS
Torch applied modified bitumen requires proper technique and equipment. An undertorched seam looks fine and leaks in the first rain. An overtorched membrane burns through. We have been doing this long enough to get it right every time.
OUR CREW. EVERY JOB.
We do not subcontract modified bitumen installations. The same crew that gives you the proposal does the work. That means consistent standards, direct accountability, and a workmanship warranty worth something because we stand behind it ourselves.
OUR PROVEN PROCESS
ROOF ASSESSMENT
We inspect your existing roof or new structure, evaluate deck and substrate condition, assess drainage and foot traffic patterns, and determine whether torch applied or cold applied modified bitumen is the right system for your building.
DETAILED PROPOSAL
You receive a written proposal covering system specification, number of plies, cap sheet type, flashing details, warranty terms, and project timeline with enough detail to compare options and make a confident informed decision before work begins.
LAYER BY LAYER INSTALLATION
We install the base sheet, reinforcing ply, and cap sheet in sequence with each layer properly adhered or torched and inspected before the next goes on. Flashings and penetration details get completed to specification before sign off.
FINAL INSPECTION & DOCUMENTATION
We inspect every seam, flashing, and transition detail before the job closes. You receive warranty documentation and a completed project record the day we finish so your paperwork is in order from day one.

FREQUENTLY ASKED QUESTIONS
What is modified bitumen roofing?
Modified bitumen is a multi-layer, asphalt-based roofing system reinforced with polyester or fiberglass and installed in layers: base sheet, reinforcing ply, and cap sheet. This gives it more redundancy and puncture resistance than single-ply systems.
What is the difference between torch-applied and cold-applied modified bitumen?
Torch-applied modified bitumen uses an open-flame torch to heat and bond each layer, creating a strong adhesive bond when done correctly. Cold-applied systems use adhesive or self-adhering membranes without heat. Both produce solid results when installed by an experienced crew.
How long does a modified bitumen roof last?
A properly installed modified bitumen system typically lasts 15 to 20 years. System longevity depends on the number of plies, cap sheet quality, drainage conditions, foot traffic, and how consistently the roof is inspected and maintained over its service life.
Is modified bitumen a good choice for roofs with heavy foot traffic?
Yes. The multi-layer construction resists punctures and abrasion better than a single membrane, making it a practical and reliable choice for commercial roofs that see regular access from maintenance crews, HVAC technicians, and equipment personnel throughout the year.
How does modified bitumen compare to TPO and EPDM?
Modified bitumen is thicker, more puncture-resistant, and better suited for high-foot-traffic roofs. TPO is white and reflective, making it better for energy efficiency. EPDM has a long track record and strong cold-weather performance. We help you choose based on your building’s actual conditions and priorities.
Do you repair modified bitumen roofs that you didn't originally install?
Yes. We repair modified bitumen systems regardless of who installed them. We assess the membrane condition, identify what is failing and why, and repair it properly using compatible materials, whether that means patching a blister, resealing flashing, or replacing a damaged cap sheet section.
