What Do You Need in Your Spray Foam Truck ForRoofing?

At Intech Equipment and supply, we know what roofing contractors need in their spray foam truck. Whether they need to perform a minor touch up or work all day on a high-volume coating job, contractors need dependable products to complete their projects on time. We recommend products from top brands like Graco and PMC for their dependability and great reviews from real customers. We also carry accessories and sprayers from other manufacturers that also perform great in the field like Red Dragon.

If you are looking for a one-stop-shop thathas everything you need to get started on coating your next roof with SPF, lookno further. Here are a few pieces of equipment you need in your spray foam truck.

Roofing Equipment Needs

Spray foam roofing contractors need industry-specific equipment to meet the unique demands of SPF roofing applications. For the typical roofing insulation job, contractors need to evenly lay out polyurethane foam over the roof's substrate and wait for the liquid to expand into a seamless foam that is about 1.5 inches thick. Then, contractors must coat the SPF with a protective layer of acrylic or elastomeric silicone coating to guard it against moisture, heat, sun, fire, and impacts. Both processes require a proportioner, spray foam gun, and additional sprayer, along with other SPF roofing accessories.

Proportioners for Roofing

Your proportioner is the main item you need in your spray foam rig. This sophisticated machine will heat and pressurize the polyol/resin and isocyanate from separate material drums and make them ready for mixing inside the spray foam gun. Here are a few proportioners that we recommend for roofing applications:

  • PMC's PH-2 Proportioner is both affordable anduser-friendly. Its rugged design and an easy-to-use electrical console thatallows fast troubleshooting. 
  • Graco's Gusmer? H-20/35 GH-2 Hydraulic proportioner is Graco's classic, simple, yet durable machine with an impressiveperformance. Its affordable price also makes it an incredible value.
  • Graco's Reactor? line of proportioners have been trusted for over 20 years as dependable machines for applying insulation on roofs. Right now, the Reactor 2 is the latest in this series. Also, an upgrade to track ratio balances is now available that can help prevent costly errors.

Roof Coating Guns

Contractors who apply spray foam to roofs need both precise guns to target joists and underneath of roofs to high volume areas that need to apply evenly. Graco recommends these spray foam guns for maximum precision and performance:

  • The Graco Fusion Air Purge Gun is a popularplural-component gun that can take care of many different types of spray foamjobs. It prevents clogging through its convenient air blast tip, reducingdowntime, which is a common problem for spray foam guns. The Graco Fusion AP isa must-have for Graco roof coating rigs
  • The Graco GX-7 & GX-8 Guns are dependableand have great pattern control. They are well-suited for tough conditions,which is ideal for a roofing contractor who often works in unpredictableweather. Its best for low output, polyurethane, fast-set polyurea, and hybridcoatings.
  • The PMC PX-7 Spray Gun is a personalrecommendation from the PMC brand. This gun is strong enough to handle toughroofing jobs. If you need a rugged gun that is going to last for years withconsistent care, this should be your next purchase.

Sprayers For Roofing

Many SPF roofing applications require two-partcoatings to protect the spray foam insulation from the sun, heat, moisture, andother hazards associated with constant exposure to the outdoors. You need anadditional sprayer to apply a protective acrylic or elastomeric siliconecoating with embedded granules to 'seal the deal.' Here are a couple of sprayguns that are often a good fit for a spray foam truck. These are also usefulfor applying primer before applying spray foam.

  • Graco XP Sprayers are user-friendly andprovide a great spray quality that is on ratio. These sprayers are ideal forapplying fast-curing materials. They also save you money by using less clean-upsolvent. These high-quality sprayers can handle long hoses and high-viscositycoatings as well and are easy to maintain to boot and are rust and dentresistant.
  • Roofmaster Spraying Systems are alsolong-lasting and versatile. Many of our clients appreciate products like the TripoxSprayr to apply light products like primers to a roof before applying sprayfoam.
