Spray foam is a relatively new material used for roofing purposes, but also one that is quickly gaining popularity for the great features and benefits it offers, such as energy-efficiency,
durability, resistance to the elements, easy application and low maintenance needs. Here are some of the benefits provided by spray foam roofs by flat roof repair Chicago – if you think you can use them, too, you should definitely consider getting a spray foam roof.
Seamless Construction for Improved Resistance to Water
Roofing seams – the area where two roofing components or sections are joined – are more prone to developing leaks, which also means that the more seams a roof has, the more sensitive it becomes to water penetration. Spray foam roofs are seamless, so they reduce the risk of developing leaks to the minimum.
No Leaks Around Flashing
The flashing used around chimneys, in roof valleys or around other types of openings, such as skylights are also components around which leaks can develop more easily. Spray foam conforms perfectly to the roofing substrate, forming an impermeable layer that eliminates the risk of flashing leaks.
No Ponding Water on the Roof
Spray foam can be used to create a perfectly smooth surface, without any lower areas as well as to correct the sloping angle of the existing roof to make roof draining more efficient and to eliminate ponding water.
Reduced Roof Weight
Spray foam is a very lightweight material – it weighs only around 3 pounds per cubic foot. This feature makes spray foam the perfect solution for re-roofing projects that involve buildings unable to hold too much added weight.
Excellent Thermal Protection
Spray foam is a material with excellent insulation qualities, with R-values usually in the 6.2-6.5 range, higher than in the case of many other roofing and insulation materials. A spray foam roof can be the solution you need to reduce your heating and cooling-related energy bills – the seamless construction and the outstanding heat insulation properties of the material will maintain the temperature inside the building stable and will reduce the energy necessary for cooling and heating the building, thus reducing energy bills as well.
Spray foam is also a very strong and flexible material, able to withstand the contraction and expansion caused by temperature changes, so it can be applied on roofs in areas with wide temperature variations.
Durability and Resistance to the Elements
The coating applied on spray foam roofs can protect the roof for about 15-20 years. Spray foam is resistant to water, punctures and the right type of coating makes it UV-stable as well. Spray foam is odourless and not attractive to pests, thus helping building owners eliminate one more risk.
Easy Application and Low Maintenance Requirements
Spray foam roof can be applied easily and quickly and the curing process takes only a couple of days, so the installation process causes only minimum disturbance in life of the building’s users. Spray foam is also very easy to maintain – it does require regular, six-monthly inspections and cleaning, but the issues detected on the roof will be minor and easy to correct in most cases.
