Heavy-Duty Modified Bitumen Roofing in the DFW Metroplex & Beyond
Ultra-tough, asphalt-based multi-ply waterproofing engineered for industrial facilities, commercial flat roofs, and severe Texas weather.
Proven Multi-Ply Protection for North Texas Facilities
High-Impact Resistance for Commercial & Industrial Roofs
When commercial buildings, manufacturing plants, and retail facilities require exceptional durability and resistance to foot traffic, Modified Bitumen (Mod Bit) is an industry-leading standard. Evolved from traditional built-up roofing (BUR), modified bitumen combines polymer-modified asphalt with reinforcing fiberglass or polyester mats to deliver superior tensile strength and flexibility.
At
RAM Roofing Group & RAM Contractors Group, we specialize in the custom installation, repair, and maintenance of high-performance modified bitumen systems across McKinney, Dallas, and the DFW Metroplex. Whether installed via torch-down, cold adhesive, or self-adhered application, Mod Bit provides a multi-layer waterproof barrier designed to withstand heavy hail, standing water, and extreme thermal expansion.
Core Benefits
Built for Strength, Flexibility, and Longevity
Puncture & Tear Resistance
Reinforced multi-ply construction makes Mod Bit ideal for flat roofs with frequent HVAC maintenance or rooftop foot traffic.
Extreme Weather Endurance
Advanced polymer additives (APP or SBS) allow the membrane to expand and contract smoothly during volatile DFW temperature shifts without cracking.
Sealed Waterproofing
Seams are fused together using heat-welded or specialized adhesives, creating a continuous, seamless seal that prevents lateral water movement.
Reflective Energy Coatings
Available with granular surface caps or reflective energy-saving coatings that block UV rays and reduce interior cooling costs.
Low Maintenance & Easy Repairs
Exceptional structural integrity leads to lower life-cycle maintenance costs, and localized punctures can be quickly patched.
Preventative Maintenance & Inspections
Annual diagnostic sweeps to assess seam integrity, flashing, roof penetrations, and drainage systems to maximize manufacturer warranty coverage.
Emergency TPO Repairs & Leak Stop
Rapid-response seam re-welding, membrane patching, and drain clearings to prevent severe structural damage after severe DFW hail storms.
Aggregate Re-Ballasting & Spudding
Removal or leveling of old gravel (spudding) to inspect underlying membranes, perform structural repairs, and re-apply fresh protective ballast.
Preventative Industrial Inspections
Biannual sweeps to check gravel coverage, clear clogged scuppers and internal drains, and inspect flashings around HVAC curbs and exhaust vents.
Our Modified Bitumen Application Methods
Tailored Installation Options for DFW Property Managers
APP Torch-Down Systems
Heat-welded application utilizing a torch flame to melt asphalt backing directly to the substrate for an airtight, immediate bond.
SBS Cold-Applied & Self-Adhered (Peel-and-Stick)
Torch-free installation ideal for sensitive commercial facilities where open flames are restricted by safety codes.
Multi-Ply Cap Sheet & Granule Coatings
Mineral-surfaced cap sheets that add severe UV resistance, Class A fire protection, and aesthetic color-matching options.
Targeted Mod Bit Repairs & Re-Sealing
Rapid response leak diagnosis, seam re-welding, and flashing restoration around rooftop HVAC curbs and drains.
FAQ
Frequently Asked Questions About Modified Bitumen Roofing
What is the difference between APP and SBS modified bitumen?
APP (Atactic Polypropylene) modified bitumen is plastic-modified, making it highly rigid, UV-resistant, and ideal for torch-down applications. SBS (Styrene-Butadiene-Styrene) is rubber-modified, giving it superior elasticity and cold-temperature flexibility, making it ideal for cold adhesive or self-adhering systems.
How long does a modified bitumen roof last in Dallas, TX?
A professionally installed multi-ply modified bitumen roof typically lasts between 20 to 30 years in North Texas, provided routine inspections and drainage checks are performed.
How well does modified bitumen withstand Texas hail storms?
Exceptionally well. Because modified bitumen systems are multi-ply and asphalt-reinforced with fiberglass or polyester mats, they offer far higher puncture and impact resistance against severe DFW hail than thinner single-ply membranes.
Can modified bitumen be installed over an existing roof?
Yes, if local building codes allow and the existing roof substrate is dry and structurally sound, a modified bitumen overlay can be applied over smooth built-up roofs or low-slope surfaces, saving on tear-off expenses.
Is torch-down roofing safe for commercial buildings?
Yes, when executed by licensed, experienced contractors following strict safety protocols. However, for facilities with strict fire codes or chemical safety risks, we offer high-performance self-adhered (peel-and-stick) or cold-applied adhesive SBS systems as safer, torch-free alternatives.
