What if there was a better way, a less expensive and more effective way to keep your roof free from leaks. What if was possible to maintain your roof forever? Nu Hope is a company that makes medical products. The office is cooled by 3 air conditioners but only two large swamp coolers cool the entire shop and storage area. The majority of the building gets hot during the summer months because heat from the sun transfers through the roof and into the building. The roof was fourteen years old, nearing the end of its useful life. The skylights, vents, drains and other roof penetrations had been patched several times. These are common places for leaks to start because often when a roof is installed, penetrations are not primed or properly flashed. Century Roofing showed them how to maintain their roof indefinitely without having to tear it off, cool the interior shop area without adding new and expensive air conditioners, and have the new sustainable roof system help pay for itself. Extra Tough Roof Maintenance System Century Roofing offered a solution that was both safe and odor free; a cold process roof that combines polyester and emulsion over the existing roof, avoiding having to tear it off. A 2-ply polyester maintenance roof system was installed directly to the existing roof. Roof top penetrations were scraped down to bare metal, primed and sealed with an elastomeric material. Emulsion and polyester was applied. Acu-Flex, one of the best white acrylics from Advanced Coating, finished the job.
Emulsion is a mixture of pure asphalt and bentonite clay. It is far superior to asphalt that is used in hot applied roofs. Emulsion seals off the roof and creates a thick waterproofing layer that will slow the aging process by keeping the roof pliable. Polyester ply sheets are much tougher than conventional fiberglass. They have the ability to expand and contract without splitting on a large roof like the roof at the Nu-Hope facility.
Cool White Roof Coating Century Roofing used Advanced Coating’s Acu-Flex material, one of the best acrylic coatings available. The coating will cut the heat on the roof by up to 80º on hot summer days. White acrylic coatings can save up to 50% on cooling bills. The best part about using polyester and emulsion is that you can maintain your roof for about 25% of the cost of a new roof. Every 10 years or so an additional coating of Acu-Flex is all you will need to maintain this roof. Two main reasons for roof failure are:
A white coating of Acu-Flex blocks 100% of the ultra violet light. The highly reflective coating dramatically lowers temperatures on the roof, greatly reducing expansion and contraction. These two roof killers are brought under control. Upon completion Nu-Hope received a 10-year warranty. Century Roofing has been using emulsion and acrylics for three generations. We have been combining them with tough polyester reinforcement for over 17 years. May we put three generations of waterproofing know how to work for you?

Cleaning the roof.
All penetrations are scraped down.
All the penetrations are primed to create a solid long lasting bond to the new maintenance roof system.
Two layers of extra tough polyester are bonded to the existing roof.
Fiberglass roving is chopped through a special gun the same time the emulsion is applied. This creates a thick waterproof barrier that water cannot penetrate.
Two layers of Acu-Flex white coating are sprayed onto the roof. This will reduce temperatures and save money.
