What is SPF or Spray Foam Roofing?
If you have heard of spray foam insulation, SPF roofing uses the same cost-effective, smart technology. Nashville roofing professionals apply closed-cell or high-density spray polyurethane foam over either new construction or the old roofing materials on flat or low-slope roofs. The spray starts as two liquids, so it easily adheres to any and all roof surfaces. It can seal against moisture and insulate around HVAC units, skylights and vents. The liquids chemically react with one another and expand into an insulating foam and a seamless seal.
With spray foam roofing on a Nashville building, roofers don’t need the usual joints and fasteners used in other roofing types. It can be applied over a new roof or existing roofing, including asphalt shingle, metal, wood, or concrete. A silicone, acrylic, or polyurethane topcoat adds a UV light resistant barrier which reduces heat absorption on hot Nashville days.

Spray Foam Roofing Pros
|
FastWhile preparing the surface could take some time if there is lots of debris on the present roof, applying spray foam roofing to Nashville buildings usually only takes a day or so, depending on the size of the roof. The additional topcoat adds a day or two, but spray polyurethane foam roofing is fast compared to other roofing types.
Easy InstallationOnce a roof is cleaned, and all debris is removed from a commercial building or home in Nashville, spray foam roofing installation is a matter of evenly spraying every surface on the roof. Installers only need a few technicians for a roofing job. Spray foam roofing contractors use high-pressure machines called reactors to ensure complete coverage and even distribution. They apply thin layers until they have the thickness they want. Windows, skylights, vents, and HVAC units that normally slow roofing jobs down pose no problems. There’s no need to remove old roofing materials either as long as they are clean and debris free.

EffectiveThe insulation level, measured as R-factor or R-value, is higher for SPF than for other roofing materials. Spray foam insulation comes in three levels: open cell, closed cell, and high density. Open-cell has a good R-factor, but closed-cell is denser and has higher resistance numbers. High-density spray foam insulation has the highest insulating ability of the three. Foam roofing contractors use the two higher levels, closed-cell, and high density, for roofing.
A higher R-factor means hot air stays out in summer, and cold air stays out in winter. The air-cooled or heated by your HVAC system also doesn’t escape as easily. Because the insulation completely encases the roof and leaves no gaps, your HVAC system doesn’t have to work as hard to keep up. The seal produced not only prevents air from moving in and out, but the waterproofing nature of spray foam also makes it the best at preventing roof leaks. The spray foam roofing plus the UV light-resistant topcoat keeps the roof cooler in hot Nashville summers. In the city, this topcoat, together with the roof foam, helps prevent an Urban Heat Island.

EconomicalFoam roofing cost is affordable for a couple of reasons. Fewer workers are needed, and installation is fast. The excellent insulation factors save money on heating and air conditioning bills. Spray foam roofs last much longer than shingled or metal roofs, and maintenance costs less. When erosion or damage does occur, repairs are simple and inexpensive.
Long-LastingSpray foam roofing in Nashville typically lasts 30 years and can last up to 50 years with proper maintenance. While estimates vary, asphalt roofing usually lasts between 15 and 20 years. Concrete might last 20 years and metal 15-35 years.

GreenAdding new roofing usually entails removing old material and adding it to the landfill. Most roofing materials like asphalt shingles must be replaced regularly, which means more discarded material. Spray foam roofing is a green alternative for Nashville commercial buildings and homes. The old material can stay in place, and the urethane foam roofing is added right over it. You don’t need to replace spray foam roofing for your building in Nashville. Any damage can easily be repaired by adding more roofing foam.
Because the spray polyurethane foam roofing and topcoat resist UV light and reduce heat absorption, it cuts the Urban Heat Island effect. You may wonder why, in the city, temperatures are higher than in rural areas, especially at night. This happens because building roofs and other surfaces absorb and hold heat even after the sun goes down. Roofing foam insulation helps prevent Urban Heat Island effect. If the air outside stays a couple of degrees cooler, you won’t pay as much for air conditioning. Using less electricity benefits the environment. SPF roofing systems use environmentally friendly materials, too.

Easy MaintenanceAfter spray foam roofing is installed in Nashville, you, your maintenance personnel, or spray foam roofing contractor should inspect the roof twice a year in the Spring and the Fall. A severe storm or unusual wear and tear can sometimes cause damage.
But foam roofing repair is fast and easy. Any problems that appear can easily be fixed by adding additional roofing foam. While other roofing materials that fail need to be removed and replaced, just adding extra roofing foam easily repairs any damage. |
Spray Foam Roofing Cons
Application Errors
Untrained spray foam roofing contractors can easily do several things wrong.
- Preparation - If the previous roof is not cleaned and cleared as it should be, the spray foam roofing on a Nashville business could easily fail and need to be redone. Be sure your contractors only employ certified installers.
- Mixing - Without the proper certification, an installer can mix the two chemicals in the wrong proportions. They must be combined in exact percentages to react with one another and produce effective insulating foam.
- Spraying - Unqualified workers might spray the foam unevenly and interfere with the coating’s effectiveness. Too thin a layer will not insulate as well as possible, and too much can mean the foam could crack. The thickness needs to be built gradually. Each thin layer must be allowed to cool before the next spray can be added.
Limited Application Windows
Spray foam roofing must be applied to your Nashville home or business during the right atmospheric conditions. Temperatures should be moderate and humidity low. Foam roofing contractors look for good weather conditions to schedule the installation. This can be frustrating to everyone involved but installing spray polyurethane foam roofing in the wrong weather conditions could mean redoing the job.
