Weather Flexibility | Extremely Durable | Long-term Cost Efficiency
Spray Polyurethane Foam, more commonly known as SPF, is an environment-friendly roofing system for commercial, industrial, and manufacturing establishments. SPF is a liquid material that eventually expands into a foam after being sprayed. It creates a solid layer of foam that coats an existing roof system.
Because it is sprayed on as a liquid which expands into foam, SPF roofing can be installed fairly quickly and easily.
The materials create thermal, air, and moisture barriers, allowing them to provide better insulation and help regulate the building’s temperature.
When properly maintained, spray polyurethane foam roofing can last over 50 years.
SPF stands for Spray Polyurethane Foam. It is a type of polymer formed when large molecules are joined together by urethane. Polyurethanes can be flexible or rigid and are used in a variety of ways—in fabrics, cars, resins, roofing, and more. The polyurethane foam used in roofing is sprayed as a liquid which expands into foam. Once the foam hardens, it is extremely durable and provides exceptional insulation.
Cost varies according to how thick the SPF needs to be and the structure of the roof. We estimate SPF roofing to cost between $4 and $7 per square foot, but the best way to know is to contact us for a complimentary re-roofing estimate.
For the best adhesion, the existing roof layer should be clean. First remove large debris by sweeping, and then pressure wash the roof. SPF roofing is easy to lay over an existing roof, so the existing structure will not need to be stripped unless it is damaged or if there is more than one roof.
You can find patch material in typical home improvement stores, but if you plan to do the patch work yourself, make sure you follow instructions carefully. You’ll need to assess the damage on your roof. If you find more than 10 cracks, dents, or holes within 100 square feet, you should contact us to assess the damage.
When it comes to re-roofing with SPF, it’s best to find a contractor familiar with SPF roofing to do the work. SPF cannot be applied on cold, wet, or windy days, and the existing roof needs to be clean and completely free of moisture. It is a two step process. SPF is sprayed first followed by a coating to protect from UV rays. If an SPF roof is not installed properly, it will affect the roof’s lifespan and durability.
It’s not easy to remove a spray foam roof because of the nature of the material. Polyurethane sticks well to surfaces and hardens quickly. To remove it, you will need professionals who can sand or grind the foam down and then blast it off. It’s a labor intensive process. It’s much easier to maintain your SPF roof with periodic examinations for holes or divots. With care, a SPF roof will last, on average, 20 to 35 years.
Spray Polyurethane Foam on its own begins to degrade quickly under direct UV rays. For this reason, SPF roofing always includes a second layer of coating, either silicone or acrylic, to protect the SPF from UV rays. With this second layer, SPF is highly durable and resistant to sunlight.
Yes. SPF roofing is very effective at sealing and insulating your structure. Its liquid application allows it to fill holes and crevices easily. The foam acts as insulation and creates an airtight structure. Your cooling and heating bills will decrease because the roof no longer has leaks, cracks, or other openings where energy escapes. Energy savings can be from 15% to 35%, depending on your structure and the thickness of the spray foam. The thicker the spray foam, the higher the R-value will be.
Diversified Roofing provides complimentary re-roofing estimates. Simply contact us and we will schedule a consultation and consider whether SPF roofing will work for your structure and estimate the cost.
At Diversified Roofing, we want to provide the best roofing solution for your commercial property, whether that is an industrial plant, large warehouse, or manufacturing facility.
We understand how important a good roof is to help regulate building temperature and reduce cooling bills as much as possible.
And that’s why SPF roofing may be a good solution for your business.
SPF roofing is not a popular type of commercial roofing material. It has only been recognized a couple of years back. However, the technology for it has been around since the 1960s, which was available for industrial, commercial, and even residential roofing systems.
In general, the SPF roofing system can be used in various types of climate. It is also extremely durable. If properly installed and maintained, it can last for over half a century. It’s also relatively cost-efficient, with a price range of $4 to $7 per square foot, depending on the thickness of the SPF needed and the structure of the building.
