4 Benefits of Spraying Polyurethane Foam on Your Roof

Your house’s roofing features affect insulation capacity. If you are currently looking for a way to provide insulation for your home, there is still a chance to change your situation without completely replacing your whole roof. Instead of a complete roof overhaul, you can opt for spraying polyurethane foam to insulate your home from the outside in.

When installing a closed-cell sprayed polyurethane foam (SPF) roof, you don’t need to lose the old ceiling since it can be sprayed directly over the roof. With SPF roofing, you won’t need to worry much about leaking or severe weather damage. It can insulate your home with the added benefits of energy-saving features.

To find out more about SPF, we listed below four reasons sprayed polyurethane foam is the best way to insulate your home.

  1. Energy-Conserving Features

Spraying polyurethane foam on your roof will save you from high energy costs. It has closed-cell SPF with an R-value of 6.5 per inch, which is significantly more cost-effective compared to the traditional roofing systems. Compared to the R-3 or R-4 rating of an old roof, SPF can increase it to at least R-26 or R-29, depending on the area of the fiberboard. You can have an added anti-UV degradation feature if your roof is sprayed with special acrylic top coating. This feature helps reflect sunlight and prevent UV rays from entering your house’s structure.

  1. Leakproof

SPF will make sure that your roof is free from any leaks. It can prevent piping damage that will ultimately save you from expensive renovations in the future. With four inches of closed-cell polyurethane, the foam can adhere to the roofing surface, which thereby seals the pipes and conduits across the roof. It features a semi-impermeable membrane that can prevent the cavity under the roof’s sheathing.

  1. Cost-Competitive

A spray-foam roof will save you from spending big bucks for stripping off an old roof. It can give you the same effects without the additional cost of installing a new torch-down roof or a PVC membrane. SPF can be directly added on top of the old roofing, which will give you the insulation you need for your home immediately.

  1. Sustainably Green

SPF is more sustainable than the usual PVC roofing, which is known to involve toxic chemicals in its manufacturing process. It is also the greener choice compared to another form of foam insulation that uses urea-formaldehyde. Although SPF is initially petroleum-based, it does not emit gas once the polyurethane mixture foams and cures. This makes it more sustainable than other formulations. Additionally, SPF is the greener option because you will no longer have to strip off your old roofing, which would add a great amount of unwanted and unusable debris.


Spraying polyurethane foam to your old roof is the best option if you want to improve the insulation of your home. It is both energy-conserving and sustainable, which makes it a long-lasting investment that can save you major expenses in the future. Instead of making a huge overhaul in your roofing system, consult with experts who specialize in SPF roofing. Find a team of professionals you can trust that can offer quality and performance.
