PMMA Roofing

PMMA Liquid-Applied Roofing

PMMA (polymethyl methacrylate) is a liquid-applied, fiberglass-reinforced roofing membrane that cures into a fully seamless surface โ€” a strong option for roofs with complex details, tight corners, or awkward penetrations that are hard to seal with sheet membranes.

๐Ÿ’ง

Fully Seamless

Liquid application creates a continuous membrane with no seams to fail over time.

๐Ÿ”ง

Ideal For Complex Details

Handles tight corners, pipe penetrations, and irregular roof shapes that are difficult with sheet membranes.

โšก

Fast Cure Time

Cures quickly even in cooler weather, allowing for a faster installation window.

Our Process

How PMMA Installation Works

1

Prepare The Substrate

The existing surface is cleaned and prepped for proper adhesion.

2

Apply Reinforcing Fleece

A fiberglass fleece is embedded into the first liquid resin layer for strength.

3

Apply Base Coat

The first liquid PMMA layer is applied and allowed to begin curing.

4

Apply Top Coat

A second liquid layer is applied for full thickness and UV protection.

5

Detail Work

Corners, penetrations, and transitions get extra reinforcement where sheet membranes typically fail.

6

Final Inspection

The cured membrane is inspected for full coverage and proper thickness before sign-off.
