How should I cut asphalt roll roofing?

Asphalt roll roofing is not a very thick material, and it does not come in very wide sheets. It can be easily cut with a standard utility knife, but there are a few tips to follow to cut asphalt roofing safely and properly. Make sure it is at least 50 degrees where you are working before you start cutting. Cold asphalt roll roofing cracks easy, but is nearly impossible to cut properly. When you cut asphalt roll roofing, wear safety gloves and cut away from your body. The knife can sometimes get caught and you do not want to cut yourself while releasing your knife. Change the blade often to make sure you do a clean and safe cutting job.
