Spray Foam Roofing

A common type of commercial roofing technique is spray foam roofing.  The use of spray foam roofing has many benefits that go far beyond just shedding water.  The most common reasons this type of roofing has become so well loved has to do with the material’s lightweight and durable nature.

What makes spray foam roofing a excellent choice for most types of commercial buildings is its ease of application.  This type of roof material is applied as a liquid that is sprayed onto the surface of the roof sub-decking and then expands to thirty times its thickness in liquid form.  The foam then hardens to form a hard cell monolithic roofing compound.  Because spray foam roofing is liquid when it is applied, it fills holes and cracks as it expands to make a unassailable seal.  Because spray foam roofing is lightweight, it is commonly used in most types of commercial roofing repairs.

After a spray foam roof has been applied to proper specification, the roofing contractor will then place an bonus surface over the hardened foam.  This surface is typically a layer of elastomeric coating of gravel that can be walked on for normal maintenance.

Most types of spray foam roofing are Energy Star compliant, meaning they have the added subsidy of cold utility expenditure.  For a roofing material to get an Energy Star rating, the material has to help prevent heat from radiating into the interior of the building.  By reflecting heat out of the building, Energy Star compliant roofing materials can help to lower utility cost by up 50%.

The use of spray foam roofing materials requires different procedures depending on diverse types of roofing substructures.  To ensure that someone gets the best job for their money they need to make sure they follow all application techniques that are required for a particular type of spray foam roofing.
