You’ve decided to get a spray coating to extend the life of your roof, great! But there are so many options! We can help you narrow down your choices by showing you the differences between two of the most popular roof coating types: silicone and acrylic roof coatings.
Acrylic
- Water-based acrylic roof coatings can’t hold pooling water because the formula is made out of water
- Can only be applied in certain weather, as too much humidity will cause the water-based acrylic coating to wash off or evaporate
- Most cost-effective roof coating available out of all the types, but requires multiple coatings that can add up
- Highly reflective and UV resistant
- Easy to work with
- Works great with cool roofs
- Heat resistant
- Fungus and mildew resistant
- If acrylic is elastomeric-based, it can be applied over asphalt, metal, or single-ply roofing
- Shorter lifespan than other coatings
- Very elastic and can be stretched further across buildings to morph into curves
Silicone
- Only needs one coat
- Waterproof
- Can withstand strong UV exposure
- Dries, or “cures” in 24 hours
- Can be applied in any weather
- Loses reflectivity over time
- Hard to re-coat a roof with silicone since silicone does not adhere easily. When it comes time for reapplication, the first layer must either be completely removed or re-coated
- Used for places with high traffic, like roadways, walkways, or roofs that see a lot of damage
