Samir on the thread. Measure your eave width to match the roll width. Check the roll length to calculate how many you need for your roof area.
I am Samir Shah, Garage and auto editor at Gadget Evaluator. I treat roof flashing like a torque spec: if the dimensions do not match, the seal fails. You need to know the exact width and length of the ice and water shield before you cut it.
Look at the product photo on the Amazon page. The roll diameter and the printed width are your fit check. Do not guess the coverage based on the box size.
