Definition of a Fluid Applied Membrane
An aqueous liquid suspension, applied to roofingsubstrates, which dries to a seamless, resilient,durable membrane which is flexible across a broadtemperature range.
Paint: An aqueous liquid continuous film applied at a film thickness of 3 - 8 wet mils.
Coating: An aqueous liquid continuous membrane applied (in multiple coats) at a film thickness of 8 - 50 wet mils.
What is the difference between a paint and a coating?
Benefits of Roof Coatings vs. Paint
Remains flexibleResists standing water Excellent adhesion to a variety of substratesResists UV exposure Applied at greater film thickness for increased
flexibilityResistances to foot traffic, i.e. tensile strengthHigher reflectivity and increased emissivity

Life-Cycle Costs
The sum of all recurring and one-time (non-recurring) costs over the full life span or a specified period of a good, service, structure, or system.

Considering a Fluid Applied Roof System / Roof Restoration
System?
Yes, it is definitely less expensive, but you need to know…
When do you consider Roof Restoration?
Percentage wet roofType of Roof Type of Deck/InsulationCondition of SubstrateNumber of re-roofs It’s just as important to know when not to use a
restoration system
Not every roof “Qualifies”
for a fluid applied system.
Where to Start?
Every roof needs to be evaluated.

“Qualified” roof for fluid applied system.
No need to tear off old roof.No need to raise equipment on roof.Makes most roofs better than original.Sustainable, Renewable…lower life-cycle cost.Substantial savings over other conventional roofing

Repairing seams is standard roof maintenance on seamed roofs.
Seamless roofs require less maintenance: lower roof life-cycle costs

TEMPERATURES
A 7 story building is exposed to more radiation on the walls than on the roof.
A single story building receives 70% of it’s solar radiation on the roof.
Radiation Exposure SOLAR RADIATION
A radiant heat barrier… Reduces surface temperatures by as much as 20˚ C
Reflects between 80% and 87% or radiant heat
Limits radiant heat absorption between 15% and 20%
Reduces energy consumption by as much as 40%

“… After the application of the coating, the average peak temperature in the warehouse area dropped to 86° F, a decrease of 17° F. “

“… a 64° F reduction in roof surface temperature, a 23° F reduction in attic temperature and a 10° F reduction in room temperature as a result of the insulative and reflective value of the coating.”
- Benjamin S., Col, Dept. of the Army
Cool Roofing improves insulation performance
“The thermal resistance of insulation installed immediately below a black membrane has been found to be up to 30% lower than advertised, when measured at peak summertime temperatures in Austin, Texas.”
- Konopacki and Akbari, 2001

Cool roof standards are designed to reduce a/c demand, save money, and save emissions. In Los Angeles they will eventually save ~$100,000 per hr.
Added roof cycle cost savings for ENERGY STAR® Fluid Applied Cool Roof Systems.
According to EPA about $40 billion is spent annually in the United States alone to air condition buildings-1/6 of all electricity generated in a year.
ENERGY STAR® qualified roof products reduce the amount of air conditioning needed in buildings, and reduce energy bills by up to 50%. – Department of Energy
Downsizes Cooling Equipment-A reflective roof can reduce peak cooling demand by 10-15%. As a result the building owner may be able purchase a smaller, more efficient and less expensive cooling system. -EPA
Existing cooling systems will not have to work as hard to maintain the same comfort levels and may require less maintenance.
Increases Roof Product life- ENERGY STAR® qualified roof products maintain a more constant temperature and reduce thermal shock; cool rain/hot roof causes sharp drop in temperature, extremes of expansion and contraction.
Thermal Shock = stress and roof degradation.

“In the past, we have struggled to maintain minus 12° F… Since the application, we have been able to maintain minus 15° F or less.”
