ABOVE: Waterproofing a concrete roof with PrimeLock Epoxy Primer and EnergyMax Silicone Coating at Andersen AFB in Guam.
Concrete slabs have a tendency to crack due to settlement, thermal contraction or structural inadequacy. Unlike other roofing types, concrete roof leaks need to be fixed.
Concrete roofs need a breathable coating that can withstand ponding water. We use silicone roof coatings on a majority of our concrete roof coating jobs.
EnergyGuard Aromatic Polyurethane is a high VOC product and cannot be shipped to California. Use PrimeLock Epoxy Primer and EnergyMax Silicone Coating instead.

How long will the roof coating system last?
Longevity of a roof coating system depends on the coating chemistry, installation integrity and maintenance. All our 30 dry mil systems are eligible for a 10 year warranty when installed by an approved contractor. We can do this because we are confident that it will last longer than that.
Can I apply the product myself or do I need a roof contractor?
It depends on the size and condition of your roof. A small, simple roof may qualify as a weekend job for a building owner. A large roof that leaks and needs repairs should definitely be restored by a roof coating contractor.
