1About the building
Does the building have electrical service, or a metal water or gas line running to it?
2Roof shape and size
What shape is the roof?
Does anything rise above the roof or extend past the eaves? Think cupolas, dormers, chimneys, vent stacks, lean-tos, or porch roofs.
How do I find my roof pitch?
Roof 12 in level, held flat Rise
  1. Hold a level flat, with one end touching the roof surface or the underside of a rafter.
  2. At the 12 inch mark on the level, measure straight up to the roof. That number is your rise.
  3. No level handy? Lay your phone on the roof or a rafter and read the angle with any free level app.
