Q: Climates
What are the climates and conditions where a sprayed polyurethane roof can not/should not be applied?
What are the climates and conditions where a sprayed polyurethane roof can not/should not be applied?
A: Climates
Spray foam roofs are just like all other roof systems; they need to be applied to a clean and dry substrate. Spray foam roofs can be installed in most regions of the world. When applying spray foam to roofs, it is recommended for best results that the ambient air temperatures range between (40 - 100 degrees F) and that wind conditions are less than 12 miles per hour (or 25 miles per hour when wind screens are being used). For best results, it is recommended to be applied when humidity levels at the point of application are below 80%. These general rules of thumb are true for most commercial roofing systems regardless of their type if you want to follow good, safe roofing practices.

Q: Cost Competitive System
Are spray polyurethane roof systems more expensive than other roof systems?
Are spray polyurethane roof systems more expensive than other roof systems?
A: Cost Competitive System
In many instances it can be less expensive, and reduce both installation time and cost for the building owner. Closed-cell spray foam both insulates and waterproofs at the same time, using the most advanced building insulation technology. Since it is spray applied it can be tailored for draining water and creating slope on a flat roof.

Q: Green Product
how do spray foam roof and wall systems help preserve the environment?
how do spray foam roof and wall systems help preserve the environment?
A: Green Product
SPF roofs help reduce dependency on oil, they conserve energy natural resources, and they reduce total energy consumption. They also have no ozone-depleting effects or Volatile Organic Compounds. They are totally sustainable because they never need to be replaced if properly maintained. As a result, the roofs never need to be removed or end up in a landfill.

Q: ROI

A: ROI
Spray foam roof systems are backed by manufacturers' warranties for periods of 5, 10, 15, and 20 years in duration. Many of the spray foam manufacturers will also provide extended warranty beyond the initial warranties outlined above based on a re-inspection and provided that any alterations and deficiencies in the roof system are addressed to bring the roof back to a warrantable condition. Spray foam roofs are truly sustainable in that they are the easiest to maintain and repair, and when properly maintained and recoated per the manufacturer's recommendations, they should last as long as the structure. The US Energy Labs at Oak Ridge define sustainable roofs as having the following characteristics: they address energy efficiency; they have a low environmental impact; they are durable with less maintenance; and there is reduced waste generation through the design, construction, reuse and final disposal stage. No other roofing system does a better job of addressing these issues than a spray foam roof. In most instances, repairs and maintenance are made using simple caulks and a coating either by the owner or a contractor. If an owner is replacing an existing roof system that is scheduled and budgeted for replacement, the ROI begins the day the new spray foam roof is installed, due to the energy savings from reduced heating and cooling costs.

A: Green Product
From an environmental standpoint, Honeywell's Enovate® is the most energy-efficient insulation product available today for commercial building. Closed-cell spray foam insulation formulated with Enovate provides superior thermal properties. Spray foam is 26-32% more energy efficient than a comparable boardstock insulation with an equal R-value when you consider spray foam's improved low temperature R-values and reduced energy loss at insulation joints and fasteners, which significantly lowers your heating and cooling costs. Spray foam's increased energy efficiency, along with a Zero Ozone Depletion Potential, makes spray foam with Enovate as valuable to the environment as it is to reducing the building owner's operating cost. Enovate is also not considered a VOC (Volatile Organic Compound) and is non-flammable. In recognition of Enovate’s beneficial environmental properties, the Environmental Protection Agency (EPA) awarded Honeywell its Stratospheric Ozone Protection Award in 2002. Spray foam roofs are an excellent choice for those seeking Leadership in Energy and Environmental Design (LEED) Green Building Rating System Certification. A spray foam roof with a highly reflective white surface provides superior reflectively and emissivity properties. These features save the building owner considerably on energy usage associated with heating and cooling the facility, abate urban heat islands, and helps slow the formation of smog-forming pollutants. Spray foam roof manufacturers are listed in the Energy Star Roof Products program. Studies at Oak Ridge National Laboratory (ORNL) and Lawrence Berkeley National Laboratory (LBNL) document the energy and reflective performance savings from spray foam roof systems.

Q: Roofing
Why did the State of Louisiana choose spray polyurethane foam as the roof system for their roof replacement of the roof that blew-off during hurricane Katrina?
Why did the State of Louisiana choose spray polyurethane foam as the roof system for their roof replacement of the roof that blew-off during hurricane Katrina?
A: Roofing
When the Louisiana Superdome’s roof was destroyed by Hurricane Katrina in August of 2005, it was replaced with a spray polyurethane foam or (SPF) roof. The system, which utilizes the new Enovate insulating technology from Honeywell International, played an integral part in the quick turnaround. After Katrina, the state wanted a roof they knew would not blow off. Having used spray polyurethane roofs on other state projects they knew it would remain leak free -- regardless of weather conditions. And only spray polyurethane foam roofing manufacturers would guarantee their roofs will not blow off at any wind-speed. Added to the significant energy savings and sustainable nature, it was an easy decision.
