Spray Foam Roofing
Benefits of Spray Foam Roofing
SPF Roofing systems from Invictus Spray Foam reduce energy costs and add improved total R-Value to the roof. White, Tan, or Grey finishes are available. White is the most reflective, which reduces energy consumption when coupled with the high R-Value of the foam monolithic leak-free barrier from the elements.
If it is time to put a new roof on your building, a spray foam roof allows you to save additional heating and cooling costs. It adds an R-Value of about 6.5 per inch. In new construction applications, you can have spray foam applied thicker to meet the insulation value you need. It saves money by not requiring insulation under your roof deck.
Another great benefit of a spray foam roofing system is that it can be applied over many different existing roofing systems. This saves on extra labor costs. It is more environmentally-friendly because it keeps the old roof in place and out of landfills.
If your building’s current insulation is adequate, we can apply a silicone coating. This will leave your roof leak-free for many years to come. Also, it can lower cooling costs due to the highly reflective color options.
What is SPF Roofing?
A 3 lbs. high-density closed-cell foam is sprayed on as a liquid. It tenaciously bonds itself to the substrate, instantly expanding into a foam. It can be sprayed in several passes to build a slope to drain and build up low areas for a uniform self-flashing roof system.
SPF is water-resistant but must be covered by an elastomeric coating to protect from UV rays. SPF roofing systems can last many years with proper maintenance and recoating every 10 – 15 years. Roofs should be inspected twice per year for damage from large hail or other mechanical damage.
How We Determine if SPF can be
Applied to Your Existing Roofing
Core samples for adhesion and moisture content are taken to determine if SPF can be applied.
Types of Roofs We Can Foam or Coat
These types of roofs can all be covered with SPF roofing systems.
- Metal roofing
- EPDM (also known as rubber roofing)
- TPO (Thermoplastic Polyolefin)
- Modified Bitumen, BuR (built-up roofing)
- PVC (Polyvinyl Chloride)
Will wind damage an SPF roof?
SPF roofing has excellent wind uplift resistance. It is ideal for extreme weather conditions for both residential and commercial buildings. It adheres and contours to the roof surface. It is self-flashing.
Another benefit of spray foam roofing is there are no fasteners. It adheres directly to the roof. Roof fasteners can cause up to 30% heat loss from a structure due to thermal bridging in a conventional roofing system.
There are different warranties you can get along with a spray foam roof. Most depend on the system you use and what the manufacturer will warranty it for. Many warranty programs include the customer needing to have us come in once a year to check your roof and repair any potential problems.
The topcoat that goes over the spray foam on your roof is what seals it. It is applied over the spray foam to protect it from UV rays. It prevents any possible leaks from occurring.
The Different Types of Topcoats Include:
- Acrylic coating
- Silicone coating
Which topcoat we use usually depends on what the manufacturer specifies in the warranty. Invictus Spray Foam believes silicone is the best coating option for extreme weather conditions. We cover most of New England with our SPF roofing and coating systems.
