If you have a foam roof covering your home, you are most likely enjoying the well-insulated benefits it provides. Foam roofing allows you to have a cool home during hot weather and it also helps retain heat in cooler temperatures. It is lightweight and is an excellent moisture barrier, since it is seamless. In time, foam roofing can break down or sustain a few areas with rips or tears. If you notice this, it needs to be repaired immediately. Here are some instructions for you to use when making a foam roof repair on your own.

Materials You Will Need

  • Ladder
  • Broom
  • Bucket of soapy water
  • Non-abrasive sponge
  • Garden hose or pressure washer
  • Gloves
  • Goggles
  • SPF compatible roofing caulk
  • Putty knife
  • Roofing foam in sprayable form
  • Foam sealant
  • Paint tray
  • Paint roller

Clean The Rooftop

Before you make repairs to a foam roof, it needs to be completely cleared of any type of debris so the foam material will adhere properly. Start by getting on your rooftop and doing a complete evaluation of the area. Walk slowly back and forth, noting areas where the foam appears compromised. Bring up a broom so you can sweep off any twigs, leaves or dirt clumps. 

Afterwards, bring up a bucket of soapy water and a non-abrasive sponge. Scrub the entire surface of the foam roof by hand to get any smaller particles of dirt or mold spores off of the surface. Rinse with a garden hose or pressure washer. Allow the roof to dry in the sun for several hours before starting the repair.

Making The Repair

Inject SPF compatible caulk into any crack or punctured area in your foam roofing. Make sure to put the nozzle in as far as possible before releasing the contents into the area. Use a putty knife to spread the caulk over the compromised area so it is uniform with the rest of the roof. Allow this material to dry completely.

Find out what type of foam was used on your roof when it was originally applied, as the spray foam will need to be made of the same material. The three types used are acrylic, urethane, or silicone. Bring your matching foam spray up to the rooftop. Put on gloves and goggles to protect your skin and eyes while you use the roofing spray. Spray the roofing foam over the areas where foam torn or ripped. Make sure to use enough of the material to completely cover foam that is not in tact. Allow the material to expand and harden over the caulk.

Sealing The Roof

After you have made repairs, seal your foam roof so the spray foam is protected underneath a barrier. Pour your sealant into a paint tray and roll it over the entire roof surface. Apply sealant yearly to keep your foam from any further damage.
