Residential Roofing / Roof Replacement
A multi-ply asphalt system engineered for low-slope durability.
Modified bitumen combines the time-tested reliability of asphalt with polymer-reinforced plies and a factory-finished cap sheet — creating a tough, multi-layer system ideal for low-slope roofs. Our crews install torch-down and cold-process mod-bit systems engineered to shed water and stand up to Gulf Coast heat and heavy rain — backed by a workmanship warranty and upfront pricing.
Fast, free, and no obligation.

Roof Replacement
Mod-bit roofs are tough, but heat, UV exposure, and trapped moisture will eventually wear them down. Here’s what our inspectors look for when assessing whether replacement is the right call.
A scaly, cracked surface pattern called alligatoring means the bitumen has oxidized and the waterproof layer is breaking down.
Blisters form when moisture gets trapped between plies. As they grow and eventually burst, they expose the underlying layers to water intrusion.
Torch-welded or adhered laps that pull apart are one of the most common entry points for water on aging mod-bit roofs.
The mineral granules on the cap sheet protect the bitumen below from UV. Bare patches mean the asphalt is exposed and deteriorating fast.
Water sitting on the roof for more than 48 hours after rain softens the bitumen, works into seams, and accelerates the breakdown of every layer below.
If you’ve patched the same area more than once, the membrane system as a whole is likely past the point of spot repair.
Why Modified Bitumen
Multiple reinforced layers mean that if one ply is compromised, the system still has protection underneath — unlike single-ply membranes.
Torch-applied mod-bit creates a seamless, heat-fused bond; cold-process adhesive systems are ideal when open flame isn’t appropriate.
The mineral-surfaced cap sheet resists foot traffic, UV exposure, and light hail — and comes in a range of colors.
Polymer-modified asphalt stays flexible in cold and stable in heat, making it a dependable choice across Gulf Coast temperature extremes.
Our Roofing Process
Every modified bitumen roof replacement follows the same five-step process, so you always know what happens next.
We inspect your existing membrane, drainage, and deck to understand what’s causing the problem.
A detailed, honest estimate outlining ply count, cap sheet type, installation method, and total cost.
If storm or water damage is covered, we handle the paperwork and speak directly with your adjuster.
Our crews tear off, re-deck as needed, and torch-down or cold-process your new mod-bit system to manufacturer spec.
A final walkthrough confirms every seam, drain, and flashing detail before we call the job done.
Installation Methods
We’ll help you choose the ply configuration and installation method that fits your roof’s structure, drainage, and budget.
APP-modified sheets are heat-fused to the substrate with an open torch — creating a seamless, self-adhering waterproof bond and a granulated cap sheet.
SBS-modified sheets are laminated with cold adhesive — ideal where open flame isn’t permitted, and offering excellent low-temperature flexibility.
Peel-and-stick modified bitumen sheets bond directly to the substrate without torch or adhesive — a clean, fast option for smaller or ventilation-restricted roofs.
