Automotive Shop Roof Waterproofing Case Study
Flat / Metal Roof
The Problem
Before
During
After
The Outcome
The new roof was applied as follows:
• Pressure wash and clean the existing roof.
• Repair and seal all cracks over 1/16″.
• Apply a primer to maximize adhesion.
• Apply an acrylic elastomeric base coat with embedded fabric as the main waterproofing layer.
• Apply two top coats for high UV resistance and long-term wear.
The advantage of an acrylic elastomeric system is its ability to easily overlay an existing surface and be readily molded around unusual penetrations and angles. The roof can be sprayed or rolled on depending on conditions. Recommended maintenance is an annual pressure washing. After 20 years, a simple reseal is recommended which consists of a new base coat application without the fabric, and a new top coat.
