To fill the cracks on the roof, Spray Foam roofing is done on the surface of the roof. It has a feature to expand up to 30 times after being sprayed and then it converts into a hard membrane and thickens. This airtight insulation is weather tight roofing and is lightweight which gives additional advantages. The pros and cons of Spray Foam Roofing are:


  • Waterproofing: Once the spray foam is applied on the surface of the roof, a waterproof layer is formed which is tough. The Sealing_Spray_Foam_Roofingchances of failure in this watertight roofing are negligible. The requirements for flashing treatments like roof edges and around roof penetrations are not required.
  • Air Sealing: Not only does this roofing give a waterproof surface, but it also creates an airtight envelope. It expands as soon as it is applied and seals all the gaps. Thus the most effective way so that any kind of air leakage can be prevented is spray foam roofing.
  • High R-value: Closed cell spray foam is supposed to have the highest R-value, being 6.5 per inch. The higher the R-value, the better is the thermal barrier. Hence Spray Foam roofing serves as an excellent thermal barrier and resists and heat exchange in a way that no other roofing material could do.
  • Low Maintenance: Expenses for maintenance are nil since there is practically no maintenance after the roofing job is complete. The insulation would not degrade for many years. But the top UV barrier is required to be renewed every 5 years and that is the only maintenance.
  • Project Completion Time: Waterproofing, air sealing and insulation, all are achieved in a single step in spray foam roofing. Hence, the time required is very less and the operations are quick. Most installations have been completed in a single day. Spray foam roofing also works effectively against any kind of sound transmission.
  • Comfort: Interior spaces have hot or cool spots and thus there is improved comfort. Climate control is also simple and in-expensive.
  • Lower Cooling costs: The UV barrier on top of the surface is a good reflector. Thus you get a cool roof and also cool interiors, reducing the cooling costs to a great extent.


  • Incorrect Application: In this form, 2 chemicals are blended, which must be performed cautiously and should be maintained. Thus inexperienced applicators can make mistakes because of which uneven applications may be the output.
  • Temperature Limitations: During wet, cool or even windy weather, applications of Spray Foam Roofing should be prevented.
  • Misinformation: Many people are unaware about the correct information and use of Spray Foam insulation since it is different from the rest.
  • Overspray: If the wind carries the spray foam, then it can harm the adjacent car finishes and vehicles. Hence they should be moved away from the surroundings.

A good knowledge about the various pros and cons that are associated with Spray Foam Roofing is essential before you decide to apply this on your building’s roof. If the correct procedures are followed, then Spray Foam Roofing will definitely give you numerous benefits.
