When it comes to roof coatings, material choice matters. Western New York’s seasonal extremes—from summer sun to winter snow—make your selection especially important.
Polyurethane Foam: The Insulating Powerhouse
Spray polyurethane foam (SPF) expands to seal cracks and provides a continuous, highly insulative layer. It’s perfect for irregular surfaces and buildings prioritizing energy efficiency.
Pros:
- High R-value (thermal resistance)
- Seamless waterproof barrier
- Great for older or complex roof geometries
Best for: Warehouses, manufacturing facilities, and buildings needing better insulation.
Silicone Coatings: The Ponding Water Champion
Silicone’s hydrophobic nature makes it ideal for flat roofs or areas where ponding water is unavoidable.
Pros:
- UV stable
- Doesn’t degrade under standing water
- Long lifespan (15–20 years)
Best for: Buildings with drainage issues or roofs with a history of water retention.
Acrylic Coatings: The Budget-Friendly Performer
Acrylic is cost-effective and performs well in moderate climates, especially when UV protection is a concern.
Pros:
- Economical
- Easy to apply
- Environmentally friendly (water-based)
Best for: Schools, offices, and lower-risk commercial properties with good drainage.
