Installing a spray polyurethane foam roofing system or repairing your existing SPF commercial roof has many huge benefits. With the energy prices skyrocketing, every business owner is looking for ways to keep their energy costs lower. The foam roof insulation solution our contractors install will change your old roof from an energy-wasteful system into a clean “green” roofing system that will help keep energy costs down. In fact, the spray polyurethane foam roofing system can pay for itself in energy savings within 7 years!
Sprayed polyurethane foam roofing systems have been engineered to provide a superior energy-efficient, long-lasting roof for any building. Foam roofing offers excellent insulation value and a smooth, durable, seam-free barrier against the elements when coated with Conklin coating systems. Foam is so lightweight – about eight ounces per square foot – it can be applied over most existing roof systems without exceeding the structural load capacity. Yet it’s amazingly strong, easily withstanding light foot traffic and other weight requirements. SPF has a long history in the roofing and coatings market where SPF roofs have recorded service lives in excess of 40 years performing in spite of nature’s highly destructive elements.
Conklin’s foam roofing systems have met the most stringent requirements for a variety of industry groups, such as Factory Mutual, Underwriters’ Laboratories, and are recognized by the International Conference of Building Officials. No matter what system you choose, Conklin has you covered for years to come.
Sprayed Polyurethane Foam represents a perfect waterproof application. The foam is made of billions of cells, so it acts as a waterproof barrier. Moisture can’t enter any structure. Therefore, SPF blocks dew and prevents building deterioration. Even if the top coat of the roofing system gets damaged, there is still underlying foam which will prevent the moisture from coming in. New Orleans once suffered a severe hail storm in which the Superdome was damaged. Thousands of small cracks appeared in the top coat, but there was no leaking for another decade!
If your SPF roof suffers deep penetration through all the layers, it is still not a disaster. The water will be isolated only to the place where the membrane is damaged. Contractors love this roofing option because it is easy to fix and repairs don’t compromise the quality of the entire roofing system.
Another often problem with traditional roofing systems is water ponding. The best thing about SPF is that it’s buildable. You can shape some areas to be thicker than others, so the problem with water accumulation is solved.
Sprayed Polyurethane Foam demands protection from UV lights and moisture. This is where the top coat plays a significant role. It protects and seals the foam from any damage. However, there are certain requirements for a top coat to be efficient.
Elastomeric: The coating must be elastic and able to stretch and return to its original shape. Elongation is the stretching of the top layer. This is necessary because the roof foam will expand and contract during the day depending on the temperatures. The coat has to be able to elongate for the minimum of 100 %.
Strength: The coating has to be able to withstand the local weather conditions and any changes. Strength, especially tensile strength, is crucial. The perfect coating should not deform when force is applied to it.
Insulation Protection: The coating should protect the foam from the vapor build up which could cause a dew. Moisture vapor could weaken the insulating properties of the foam, so protection is necessary. We base the level of water permeability on the temperature and the climate that the roof is in.
A measure of the rate of movement of moisture vapor is called moisture vapor transmission. We divide ratings into two main categories. One of them is vapor retarders and the other is breathers. Ratings are expressed in perms. So a rating of one perm means that is a retarder. Breather, on the other hand, allow a larger amount of moisture vapor.
Fire Safety: Based on how it passes the applicable code requirements for exterior and interior fire exposure, SPF ( both foam and the coating) can be rated Class A by ASTM E-108 or an equivalent testing method.
