The three main options
| Acrylic | Silicone | Urethane | |
|---|---|---|---|
| Cost | Lowest | Higher | Higher |
| Ponding water | Poor | Excellent | Good |
| Foot traffic | Fair | Fair | Very good |
| UV resistance | Good | Excellent | Good (aromatic types need a topcoat) |
| Recoating later | Easy | Silicone only | Usually easy |
Acrylic
The most common choice for foam roofs that drain. White, reflective, flexible and affordable. Needs warm, dry weather to apply. See elastomeric coating.
Silicone
Best for roofs with standing water or slow snowmelt. Excellent UV resistance. Costs more and locks you into silicone. See silicone coating.
Urethane
Tough and abrasion-resistant, good for areas with foot traffic like paths to equipment or roof decks. Often used as a base coat with a UV-stable topcoat.
Mixing systems
Some roofs get a combination: urethane on walkways, silicone in low spots, acrylic elsewhere. Compatibility matters, so the system has to be planned.
Call (505) 588-5928. We'll recommend a coating after seeing the roof.
Common questions
Which coating is most popular in Placitas?
White acrylic over foam is the most common, with silicone where water sits.
Can I choose a color other than white?
Light colors are available. White reflects the most heat.
