Modified Bitumen Roof Restoration

UV-rays oxidize the surface of the asphalt and produce a chalk-like residue. As plasticizers leach out of the asphalt, a modified bitumen or “mod bit” roof becomes brittle.

Roof Coatings for Modified Bitumen

Systems, Specifications & Material Calculators

Asphalt degradation is a growing concern. UV-rays oxidize the surface of the asphalt and produces a chalk-like residue. As plasticizers leach out of the asphalt, a “mod bit” roof becomes brittle. Cracking and alligatoring follows, allowing water to penetrate the system.

1. Hybrid System (Urethane / Silicone)

Our most popular system gives you the great adhesion and tensile strength of polyurethane plus the ponding and UV resistance of silicone. No primer needed.

EnergyGuard Aromatic Polyurethane Roof Coating
EnergyGuard Aromatic Polyurethane

Solvent-based, silver polyurethane roof coating with 300% elongation and 70% solids. Base coat and primer in one for flat roofs.

EnergyGuard Silicone Coating in Pails
EnergyGuard Silicone Roof Coating

Solvent-based, silicone roof coating with 267% elongation and 69% solids. Stands up to permanent ponding water conditions.

2. 100% Silicone System (Low VOC System)

Low-VOC system suitable for projects located in California. It uses a 2 component epoxy primer as an adhesion promoter and bleed blocker and a high solid silicone roof coating. NSF Protocol 151 compliant system.

PrimeLock Epoxy Primer
PrimeLock Epoxy Primer

Water-based, two component epoxy primer provides superior anchorage of silicone roof coatings on difficult substrates.

EnergyMax Silicone Roof Coating
EnergyMax Silicone Roof Coating

Solvent-based, silicone roof coating with 190% elongation and 97% solids. Stands up to long-term ponding water conditions. California VOC Compliant.

3. Butyl System (Vapor Barrier)

For modified bitumen roofs requiring a vapor barrier membrane. It uses an acrylic primer as an adhesion promoter and bleed blocker. The butyl coating provides up to 800% elongation. One of the highest in the industry.

PrimeLock Acrylic Primer in Pails
PrimeLock Acrylic Primer

Water-based, dark gray, acrylic roofing primer is an excellent adhesion promoter for chalky prepainted metal roofs or as a bleed blocker for asphalt roofs.

EnergyGuard Butyl Roof Coating in Pails
EnergyGuard Butyl Roof Coating

Solvent-based, butyl roof coating with 900% elongation and 45% solids. Vapor barrier membrane for rusted metal roofs or spray foam on cold storage buildings.

4. 100% Polyurethane System

A durable, reflective, roof coating system gives you ponding water resistance without being locked in to silicone.

EnergyMax Aliphatic Polyurethane Roof Coating in Pails
EnergyMax Aliphatic Polyurethane

Solvent-based, polyurethane roof coating with 350% elongation and 75% solids. A white, reflective topcoat for EnergyGuard Aromatic Polyurethane.

EnergyGuard Aromatic Polyurethane Roof Coating
EnergyGuard Aromatic Polyurethane

Solvent-based, silver polyurethane roof coating with 300% elongation and 70% solids. Base coat and primer in one for flat roofs.
