Spray Foam Roofing Pros And Cons

Spray foam is steadily becoming a valuable roofing agent given its insulating properties, high thermal resistance and capacity for keeping out air, water vapor, dust, pollen, and other pollutants. The following are some of the advantages and disadvantages of using spray foam as a roofing material to help you reach a balanced decision about choosing your next roofing agent –

  • Applying spray foam on top of the roof flooring creates a layer through which neither water nor hot/cold air can permeate. Due to its expansion properties, spray foam can seal off most gaps and nooks and is the most effective way to prevent the seepage of air.
  • Due to its high R-value (around 7 per inch for closed cell spray foam) it can maintain a steady temperature difference between outdoors and indoors, never letting the outside heat and cold to enter the interiors.
  • It’s high reflectivity also makes it a great roofing agent and enables it to act as a barrier against UV rays.
  • It helps lower power bills substantially by up to 50% when the installation is done properly.
  • Even though it is generally considered that spray foam comes at a high price, its cost as a roofing agent is comparable to wood and even though it is more expensive than asphalt it is more affordable than slate.
  • It can last for prolonged periods of time, sometimes for even decades if the elastomeric coating is redone at appropriate intervals and the roof is properly maintained.

Disadvantages

  • Spray foam is produced through a chemical reaction between two liquid compounds and it must be conducted in a carefully calibrated manner otherwise the resulting spray foam will not be strong enough and act as a faulty roofing or insulating agent.
  • Roofs which are prone to being buried under snow during the winter months and require shovelling are not recommended for being spray foam-ed. Also walking on it can gradually wear it away.
  • If your building is in the countryside where the roof is prone to nocturnal visits by local rodents and birds, then the spray foam has a high probability of being pecked and nibbled at. Thus in such situations other methods to discourage these animals must be employed if you wish to maintain the integrity of the roofing.
