Will Spray Foam Roofing Stop Water Leaks?

Will spray foam stop water leaks?

Leaks are the bane of commercial flat roofs. Many building managers consider spray foam roofing as a way to stop leaks. Is foam really a good solution for stopping leaks? The seams on a flat roof are the most vulnerable for leaks. Because foam creates a seamless barrier over the roof, covering the seams, it will prevent new leaks and might seal up pinhole leaks, but major leaks will need to be repaired before the foam is applied. For additional waterproofing, after the foam roofing is applied, a layer of silicone or acrylic roof coating is applied.

Are foam roofs any good?

If you are considering spray foam roofing, you’re going to need to weigh its pros and cons.

Spray foam roofing pros and cons

Pros

  • Easy installation: The foam is sprayed in a liquid form and allowed to expand. It easily conforms to all types of roof shapes and types.
  • Easy maintenance: These roofs require minimal maintenance. Twice-yearly inspections are recommended as well as inspections after events like hailstorms are recommended. 
  • Energy efficiency: Spray foam has a very high R-value and is a great insulator, keeping the heat out in the summer, and holding it in during the winter. 
  • Seamless and waterproof: The foam forms a seamless barrier that leaves roofs less vulnerable to leaks.

Cons

  • Small window for installation: SPF has to be sprayed in certain weather conditions. It can’t be installed when there is ice or visible dampness or surface moisture on the roof. 
  • Can be oversprayed: Wind can carry the spray as it’s being applied off the roof and onto the surrounding property.
  • Low puncture resistance: The foam is vulnerable to puncture damage and an SPF contractor has to perform the repair.

How long does spray foam roofing last?

You can expect spray foam roofing for 20 years, although most last much longer. The foam and coating that is applied over it will be more durable the thicker it is. Also both materials can be reapplied to extend your roof’s life even longer.

Can spray foam rot your roof?

Although moisture problems have been reported when spray foam roofing is installed wrong. If it is installed right, you won’t have problems with rotting. The foam allows both air and moisture to flow through it, preventing the water from ever collecting between the foam and roof. Problems with moisture will occur only if the roofer that installed the foam cut corners in the installation by plugging spaces with plastic to prevent material from leaking into areas where it shouldn’t go.  

Can I spray foam myself?

Although some people use spray foam to insulate their attics and can do it themselves, when applying spray foam to roofing, it’s better to allow professionals to do the job. Professionals will know exactly how to apply foam carefully around difficult areas like HVAC systems and vents, and they’ll be able to work their way around irregular-shaped roofs.

How to remove spray foam roofing

When you have damaged spray foam roofing and need to remove it, two options are available. You can hydroblast it using a hydroblasting machine to send high-pressure jets of water against the surface of the roof, or you can use a scarfer, a device that grinds the foam off the roof.

Spray foam roofing residential

While spray foam roofing is primarily used for commercial applications, it can also be used in residential roofing. It’s especially effective for homes with flat roofs, as these roofs will typically use the same type of roofing materials as commercial buildings. Heating and cooling costs can be reduced by as much as 50% with a foam application and you’ll have the same protection from leaks with it. Foam can also be used on shingle roofs though it’s not always as effective and has to be installed properly to prevent any moisture penetration. It can also be installed over metal roofing for both residential and commercial buildings. 

Some people worry about damage to shingles caused by spray foam used as insulation in the attic. Properly installed, this type of insulation won’t harm your shingles or affect ventilation in a negative way. It also won’t void your warranty on your shingles if you add this type of insulation in your attic.
