Modified Bitumen

Modified Bitumen

Modified bitumen is a layered flat-roof system built from asphalt reinforced with rubber or plastic polymers, then finished with a cap sheet that is torched, adhered, or fastened into place. It is a common choice for low-slope sections, porch roofs, and additions where a fully adhered, seamed membrane needs to shed Florida's heat and heavy rain. Homeowners and property managers typically look into it when an existing flat roof is aging, showing seams that have opened, or holding water longer than it should.

How We Approach a Mod-Bit Roof

• Core Sampling Tools — a small test cut shows every existing layer, so any recommendation is based on what is actually on the deck rather than a guess.
• Propane Torch Kits for Modified Bitumen — controlled torch application for a fully adhered cap sheet where that is the right system for the roof.
• Seam Rollers & Probes — every seam is rolled, then probed by hand along its full length before the job is called finished.

Finding Trouble Before It Spreads

• Handheld Infrared Cameras — thermal scanning that traces a leak back to where water is actually entering the assembly.
• Moisture Meters — direct readings through decking and insulation showing how far moisture has traveled under the surface.
• Photo Documentation Apps — time-stamped photos of each stage, shared with you as the work proceeds.
