SPF
SPF is a spray polyurethane foam. This roofing system is component sprayed. It helps with roofing that is already there and needs to be repaired, or if insulation needs to be added. This is a top-coated system and works to protect against the sun’s rays. Here’s more information on the SPF roofing system:
- Uses elastomeric coating to protect the foam from the UV rays.
- Has a great R-value.
- Helps to protect the air from coming and going.
- Helps with insulation.
- It’s not always very durable.
- Sometimes contracts will mess up the foam.
- Has to be maintained or bigger problems occur.
- Can last from 20 years to 40 years, depending on how thick the coating is.
- If it’s properly maintained, it can last 10 years to 15 years until needing another coating.
- Uses 1-inch or more of spray foam on the surface of the roof.
- Can be seamless if put around penetrations.
- Silicone is the most known coating and is considered the best.
- Uses raw chemicals.

Understanding Roof Coatings
Since the 70’s roofing coatings have been used on buildings and other commercial properties. This is a coating that is made of elastomeric materials and is used because it is white, has a strong finish and is very flexible. This means it can stop some of the expansion of the roofing and can stop metal roofs from becoming rusted.
Using roofing coatings is one thing that has grown over time. This happened because this is a way that commercial roofing can be restored and repaired. This kind of coating is put on at 20-mil to 40-mil, all depending on what is required by the warranty.

American WeatherStar’s Ure-A-Sil
If you need to have your roofing system restored, using American WeatherStar’s Ure-A-Sil works great for roofs such as BUR, SPF, PVC, TPO, Mod Bit, and EPDM. Here is more about this kind of roof coating:
- Works for R-panel and Standing Seam metal roofs
- The building can keep the existing roof and no tear down is necessary.
- It’s applied and it can make the roof last longer than it would.
- Costs less than a roof replacement.
- Does not last as long as other roofing systems.
- Has a longer dry time.
- Has to be installed when it is not raining, snowing or freezing.
- Cannot usually be done in the winter in northern regions.
- Can last 10 years to 20 years, depending on mil and installation process.
- Comes in pails or drums.
- Can be rolled with spreaders and rollers or sprayed on.
When using this system, it is important that the roof is cleaned first. Afterwards, the roof needs to be primed. The coating will then be applied to the penetrations, seams and fasteners. This material is considered waterproof.
The last part of the roofing coating system is to add different layers of the roof coating. This is an elastomeric coating such as urethane, acrylic, silicone and more.
When choosing which kind of roofing system that you want, or which kind of roof coating that you want, find out all of the pros and cons of each system. This can help you to decide which is best for your commercial or your industrial building.
