You can reduce the possibility of major damage to your home by knowing something about the anatomy of a roof.  Being aware of what each component in the roof system does can help you decide which ones to include the next time you re-roof.  In fact, once you know what the possibilities are, there might be a modification or two that you'll want to make to your existing roof. 

At Williams Roofing we like our customers to understand all different parts and areas of their roof. 
This gives you a better understanding of how your home improvement project will be completed. Just move your mouse over the image below to view the definitions
