Why Should I Consider a Foam Roofing System?
We are the experts and the roofing contractor people trust when it comes to commercial foam roofing installations. Whether it be on your commercial flat or metal roof. Spray foam can be applied to almost any substrate including modified bitumen, TPO, tar, tar and gravel, EPDM, and many more. SPF (Sprayed Polyurethane Foam) can be applied to just about everything. It can be installed over wood, concrete, steel, and most other existing roof systems which will save you on the expense of roof removal and landfill fees. Sprayed polyurethane roofing installers can taper the foam so that it will allow water to escape areas where it normally ponds. Roof protrusions can be foamed at their bases, eliminating entry points into the roof. The foam roofs that we have installed in the Jacksonville Florida area are great for resisting the harsh climate and weather that we experience in the South. The benefits of a sprayed polyurethane foam roof far outweigh the benefits of most other roofing systems.
How Does Polyurethane Foam Work?
In its liquid form, polyurethane foam can seal all cracks and crevices. The foam then expands to approximately 30 times it's original liquid volume and creates a weather tight seal that is fully adhered to the roof. Within seconds of being applied to the roof, the polyurethane foam is dry and can be walked on. Polyurethane foam has a history of more than 35 years as a maintainable roofing system. Due to the great insulation value added to the structure by the polyurethane foam, it can greatly decrease utility bills. After the foam has been sprayed on the roof to the proposed thickness, a layer of coating is put down to protect the foam. Our coatings products not only protect the foam from the elements, they also reflect the sun's UV rays by up to 92%.
What R-Value or Insulation Value does Polyurethane Foam Give?
The thicker the polyurethane foam is applied, the stronger it is and the more thermal resistant it will be.
Density of sprayed polyurethane foam is important when it comes to strength and thermal resistance. Obviously, higher density means increased strength and higher R-value. In most cases, our sprayed foam insulation achieves an R-value of 7.14. This is an excellent value for achieving decreased heating/AC unit usage, lowering utility bills, and increasing your AC unit's lifespan.
How Long Does Polyurethane Foam Last?
Sprayed polyurethane foam roofs can last upwards of 50 years if they are properly maintained. The material covering the foam will dictate how often it needs to be re-coated. If covered with an acrylic coating it will need to be re-coated much sooner than if it's coated with a silicone coating. Typically, a foam roof will need to be re-coated every 10 to 15 years to maintain the polyurethane foam's integrity. This is a achieved by pressure washing the roof, priming the surface, and applying a fresh coating.
Qualified roof coatings can reduce the amount of energy and time that air conditioning units take to heat or cool a structure. With these products, energy bills can be reduced by up to 50%. There are certain standards that must be achieved in order to qualify for "The Cool Roof Program" supplied by Energy Star. These standards apply to the coatings reflectivity and maintenance of reflectivity. These roof coating reflect the sun's UV rays that can result in lowering a roof's temperature by up to 100 degrees.
