Replacing Your Roof
Aged, flat roofs may need to be replaced. Whatever your current roof system, a Spray Applied Roof could be a good option for Replacement. Spray-Tec Roof Systems are affordable, efficient and warranted to last 10, 15 and 20 years. With proper maintenance, a Spray Applied Roof may be the last roof you’ll ever need!
The Replacement Process
First and foremost, determine that Roof Replacement is absolutely necessary. Other Roofing Contractors may find a saturated patch of roof deck and immediately produce an estimate for Roof Replacement. Our Estimators have found that Spray Applied Systems are ideal for Roof Restoration. Tearing off just the saturated portions of the roof can save building owner’s thousands in Roof Replacement labor and material costs.

If the Roof is not a solid candidate for Roof Restoration (too much water damage, for example), a Spray Applied Roof is still a cost-effective option. Full tear-off and installation of a new roof deck must take place before the Spray Foam and Coating can be applied.
The Spray Applied Roof System is a 5 step process:
- Clean and prime the substrate
- Spray desired thickness of closed cell Roof Foam
- Spray base coat of high solids Elastomeric Silicone Coating
- Spray top coat of high solids Elastomeric Silicone Coating (light, reflective in color)
- Broadcast ceramic granules into wet top coat
Eliminate step 2 for a Silicone Coating System.
Although it is a relatively short and simple process, bad applications can do a lot of damage and might require re-application within 5 years or less. Spray Foam Roofing Contractors with at least 10 years of experience are highly recommended.
Benefits of a Spray Applied Roof for Roof Replacement
Spray Applied Roofs are Long-Lasting
The normal wear of a quality Roof Coating has a warranted lifespan of 10-20 years. Properly maintained systems can last anywhere from 25-30 years! The Roof Coating, which protects the Spray Foam Roof Insulation, can be reapplied after the initial topcoat has weathered from many years of service, making this system completely renewable.
Spray Applied Roofs are Affordable
Although the initial cost of the Spray Applied Roof can be higher than other roofing systems, it is guaranteed to pay for itself with the energy savings it produces. The renewable properties it offers (that eliminate roof replacement every 10-15 years) are additional factors to consider when calculating cost/value.
Spray Applied Roofs have Little Disruption to Building Owner
A Spray Applied Roof System can be applied in a relatively short period of time with minor disruption to building operations. There is often little to no tear-off required and the applicator’s equipment setup is minimal, but efficient.
Spray Applied Roofs are Seamless
There are no joints or seams to allow water and air to pass through the roof system into the building structure. It is a completely monolithic application.
Spray Applied Roofs Eliminate Flashing leaks
Because Foam and Coating conform to the substrate when installed, this seamless system is ideal for flashing parapet walls, equipment, skylights, and cooling towers. Many roof leaks are caused by faulty flashing so Spray Applied Roofs solve this problem.
Spray Applied Roofs Eliminate Ponding Water
Ponding water may be eliminated by adding an increased thickness of roof insulation (Spray Foam) in low areas–building up these areas and sloping the roof so that it drains properly. It also helps reduce additional weight load caused by water accumulation.
Spray Applied Roofs are Lightweight
One inch of Spray Polyurethane Foam Roofing weighs approximately 60 pounds per 100 square feet. This is considerably less when compared to a conventional, built-up roof system. This makes a Spray Foam System ideal for re-roofing, as it is possible to apply over an existing built-up roof without removing it.
Spray Foam Roofs are Rigid
Although Spray Foam Roofs are lightweight, they are also very strong and will not pack down or sag. With the elastomeric top coat, this roof is built to sustain harsh weather conditions and age with ease.
Spray Foam Roofs have the Highest “R” Value
With an “R” value of 6.2 – 6.5, these roof systems provide more thermal resistance with less material than any other roof insulation. In most cases, a Spray Polyurethane Foam (SPF) Roof will pay for itself in 5-8 years in energy savings.
Spray Applied Roofs Extend the Life of the Building
By insulating the roof deck (and applying an elastomeric topcoat), damage due to thermal expansion and contraction is eliminated. When the foam and coating is applied, it bonds to the structure. It remains flexible, moving with the structure underneath and helping enhance the structure’s strength.
Spray Applied Roofs are Easy to Maintain
Minor repairs or modifications to a Spray Foam Roof system can be made by qualified Roof Maintenance Technicians at minimal cost. Proper annual maintenance on these Systems can extend their life 5-10 years!
Spray Applied Roofs have Great Versatility
Spray Applied Roofs can be used on both new construction and to replace old roofs. Because of their unique properties, Spray Foam and Coating can be applied to flat, pitched, saw-toothed, or domed roofs, as well as those with unusual slopes or configurations. Spray foam is also an ideal application for insulating tanks, freezers, piping, ductwork, and various other projects. To learn more about Spray Foam, click here.
