Spray-on roofing foam or commonly known as SPF, Spray Polyurethane Foam, is liquid polyurethane foam that after it dries, forms a partly-solid or solid material. It has the ability to expand multiple times than its initial size and forms an airtight barrier. This unique ability performs many functions like it acts as sound and heat insulator as well as packing up spaces between roofs, chimneys and vents.
Spray-on roofing acts beautifully with regard to roofing system. Any roof that already exists can be installed with spray foam, so there's no need to worry about replacing your old roof with new ones. Furthermore, it can be applied to any roof materials, whether it is shingle, clay, concrete tile or metal roof type. It is also lightweight so there is no need to put additional support for the roof.
Leaking roof is the most frequent dilemma of all homeowners. Roofs, over the years, are likely to crack, sever and tear and this may lead to leakage. Spray-on roofing is monolithic which inhibit water to seep through any opening or hole from the roof. It seals gaps in-between breaks or holes to prevent water and air to escape.
Many architectural structures have sharp roof angles that contractors find them hard to seal. This leaves holes and openings that allow air and water to pass through. Spray foam traps air and prevents heat loss, thus making them energy efficient. It works as a thermal barrier during cold and hot season which is perfect for homes and buildings. With this, energy consumption decreases resulting to reduced monthly electrical fees.
Spray-on foam is also considered as environment friendly and safe to humans. It does not contain any harmful chemicals such as formaldehyde that put one's health at risk. Because it blocks spaces, it stops dust and other foreign materials that cause allergies into the room. Accumulation of dirt and molds that carry different bacteria which cause diseases are also avoided.
The greatest characteristic that spray foam offers is its capability to make roof to last a long time. It can last for thirty years or more when maintained well and can sustain severe weather situation such as heavy storm and hurricanes as well as heavy snow. You can spray it on your roof, but, it is best to let professional workers do the job especially with roofs that are complicated to work with.
