Two kinds, often used together
Urethane (polyurethane) roof coatings come in two main kinds.
- Aromatic urethane: tough and lower in cost, but it discolors and weathers in sunlight, so it is usually a base coat
- Aliphatic urethane: holds its color and resists sunlight, so it is often the top coat
Why choose urethane
Urethane coatings resist impact, abrasion and foot traffic well. That makes them a common choice where hail is common, on roofs with equipment that is serviced often, and as the protective coat over spray foam, which they were first developed for.
Spray foam roofingThings to know
Urethane coatings are typically solvent-based and have a strong smell while they're applied and curing, so air intakes, doors and people nearby need planning. An aromatic base coat shouldn't be left as the finished surface. As with any coating, the roof must be sound, dry and properly prepared.
Three things to discuss before coating
Base and finish
Ask whether the proposed system uses an aromatic base coat, an aliphatic finish, or both, and why that fits the existing roof.
Roof traffic
Service paths to rooftop equipment can see more wear than open areas. Show us where people regularly walk or move equipment.
Building use
Air intakes, open doors and occupied spaces matter when a coating has an odor during application and cure.
Common questions
Can urethane go over spray foam?
Yes. Spray foam needs a protective coating, and urethane is one of the common choices.
Does urethane smell?
Many urethane coatings do while they're applied and curing. Tell us about the building's occupants and air intakes, and we'll plan around them.
