Can I send you a picture of roof and let you tell me what I need
Yes, you can send a picture but we will also need the roof pitch, length of panel from ridge to eave and the panel width between the high seams. It would also be helpful to know the ground snow load for your area. There is also a spacing guide on our web site at:
