RELIABLE MODIFIED BITUMEN ROOFING FOR COMMERCIAL BUILDINGS
Tough, Time-Tested Modified Bitumen Roofing
When your commercial property needs a roofing system that’s rugged, waterproof, and built to handle years of wear and tear, modified bitumen roofing delivers. At Reliable Roofing, we specialize in installing and replacing modified bitumen (mod-bit) flat roofing systems for facilities throughout Grapeland, Palestine, Crockett, and surrounding East Texas areas.
Whether you’re managing a school, retail building, church, or light industrial facility, our modified bitumen roofs provide multi-layer protection that stands up to East Texas weather—year after year. We install each system using manufacturer-certified methods to ensure long-term durability, compliance with local code, and peace of mind for our commercial clients.
What Is Modified Bitumen Roofing?
Modified bitumen is a multi-ply asphalt-based roofing material designed for low-slope and flat roofs. Reinforced with fiberglass or polyester, it is modified with either APP (atactic polypropylene) or SBS (styrene-butadiene-styrene) for flexibility and resistance to cracking, UV rays, and extreme temperatures.
Key Advantages of Modified Bitumen Roofing:
- Multi-Layer Strength: Several layers create a thicker, more puncture-resistant barrier
- Waterproofing Power: Torch-down or cold-adhesive seams reduce water intrusion risk
- Great for Foot Traffic Areas: Durable surface resists damage from maintenance crews and rooftop equipment
- Proven Performance: Track record of 20–30+ years in commercial roofing environments
- Repairability: Easy to patch and re-seal as needed over time
- Flexible in Cold or Hot Conditions: Adapts well to East Texas seasonal swings
Where Modified Bitumen Works Best
Modified bitumen is often the go-to system for:
- Churches and schools
- Strip malls and shopping centers
- Public facilities and government buildings
- Warehouses and service shops
- Utility buildings and older flat-roof structures
Because of its rugged multi-ply construction and enhanced puncture resistance, it’s ideal for buildings with foot traffic, aging decks, or roofs where durability is a higher priority than reflectivity.
Need a more energy-efficient or reflective system? Compare with our metal roofing systems for hybrid roof designs or large-scale commercial installations.

Our Modified Bitumen Installation Process
At Reliable Roofing, we handle every modified bitumen installation with precision and care—from tear-off to torch-down.
1. Evaluation & Scope Planning
We begin with an on-site assessment to evaluate existing conditions, including drainage, substrate health, and insulation levels. For roof replacement projects, we determine the best way to tie into existing systems or upgrade for performance.
2. Roof Prep & Deck Repair
We remove any existing membrane, clean and repair the substrate, and install insulation layers as needed for thermal protection and slope correction.
3. Modified Bitumen Application
We apply multiple layers using either hot asphalt, cold adhesive, or torch-down techniques depending on the chosen product. Seams are bonded tightly to ensure waterproofing and membrane integrity.
4. Flashing & Detailing
We seal all rooftop penetrations—vents, HVAC curbs, parapets—with reinforced flashing for complete waterproof protection.
5. Final Inspection & Cleanup
Once the system is complete, we clean the site, walk the roof with your team, and provide warranty documents and care instructions.
