Elastomeric roof coating is the family name for coatings that stretch and come back. Acrylic, silicone and polyurethane are all elastomeric. What they share is the ability to move with the roof deck through daily heat and cold without cracking, which is where old roofs usually fail first.
On a commercial roof in San Jose, CA, a dark membrane can swing a long way in temperature from a cold night to a sunny afternoon. That movement works seams loose and splits flashings. A properly built elastomeric roof coating bridges those joints with one continuous film and reinforcing fabric at every transition.
We pick the chemistry to fit the roof. Polyurethane base coats handle foot traffic and impact well. Silicone handles ponding. Acrylic is economical on good slope. Sometimes the right system is a urethane base with a silicone or acrylic top coat.
The work starts with a moisture survey, then cleaning, repairs, roof seam and fastener sealing, primer where needed and the coats themselves, checked with a wet-mil gauge as we go. Call (833) 441-4944 for an elastomeric roof coating assessment in San Jose, CA.
