As a homeowner, it is important that you make informed decisions, especially when you are having major home improvement projects like a roof replacement done. It is difficult to do this when terms are being discussed with you and you have no idea what these terms mean. The professional at BP Builders want to share some tips you should know.

1. Class A, B and C Fire Rating

Fire rating refers to how roof materials are rated based on their ability to resist fire coming from an outside source. According to ASTM E108, Class A represents the highest rating for fire resistance, meaning roofing with this rating can handle severe exposure to fire. Class B roofing materials, on the other hand, are able to withstand moderate exposure while Class C roofing materials can only handle light fire exposure. Needless to say, it is wise to choose roofing materials with Class A rating for your home and family’s protection.

2. Natural Ventilation

These are installed by roofers in openings in your attic. The roofers choose the best position for the ventilation system so that it can make use of natural air flow, drawing either moist winter air or hot summer air out and having fresh air replace it.

3. Flashing

These are pieces of metal that are applied at roof joints to prevent water seepage into your home. Areas where flashing is typically installed include chimneys, dormers, adjoining walls and vent pipes. Galvanized flashing should be at least 26-gauge for superior durability.

4. Coverage

This term refers to the amount of protection from weather elements that a particular roofing material can provide. This is dependent on how many layers of material the roofers install between the deck and the surface of the roofing that can be seen.
