What is elastomeric roof coating?
A flexible, liquid-applied membrane coating sprayed or rolled onto flat or metal roofs to seal seams, reflect sunlight, and extend roof life.
An elastomeric roof coating is a rubber-like liquid you apply directly to an existing roof surface to seal it and protect it from the elements. The coating stretches and contracts with temperature changes, staying flexible even in cold Connecticut winters, which prevents cracks and keeps water from getting underneath.
These coatings work best on flat roofs and metal roofing, including metal standing seam systems. They're rolled or sprayed on as a continuous layer that bridges small gaps, seams, and minor surface damage. The reflective finish bounces UV rays away, which helps lower roof temperature and reduce cooling costs during summer months.
Elastomeric coatings typically cost less than a full roof replacement and add years to an aging roof's life. They stick to concrete, asphalt, metal, and other common flat-roof materials. A contractor will clean and prime the surface first, then apply the coating in one or more coats depending on the manufacturer's specs and existing roof condition.
If your roof is sound structurally but showing age or minor leaks, an elastomeric coating can buy time before replacement becomes necessary. Flat-roofing contractors in Connecticut often recommend this option for commercial buildings, warehouses, and homes with low-slope roofs.
