The permit goes to the Fire Department
Roof permits here are handled by Inspectional Services, which sits inside the Fire Department, and the counter is closed on Wednesdays. We know where the file goes and which days it moves. That is a week you do not lose guessing.
We measure the ice shield from the warm wall
Hanover Park wants the membrane at least 24 inches inside the warm face of the exterior wall, and it wants it in every valley, not just along the eaves. Measured from the outside face it lands short and it fails. We set it where the inspector will look for it.
Roofers here post no bond, so ask
Every other trade in Hanover Park has to post a permit bond. Roofers are excused. That is a gap a fly by night outfit can walk through. We are licensed and bonded in Illinois, family owned, based in Westmont, and you can ask to see the paperwork before you sign.
