Best roof pitch?

If you have snow I would err on the steep side. On the other hand a shallower pitch saves a bit of plywood and shingles plus its easier to walk on.

A BTW, do yourself a favor and put ice and water shield from the edge of the roof all the way to the top of the panels. The area under the panels is not the place for roof leaks.

Run PV watts for your location.enter your data and then vary the tilt angles.

Thanks.. The PV watts calc says tilt in degrees should be 20 for Iowa City Iowa..

Would there be a advantage building a 4:12 (18.5 degrees) or 5:12 (22 degrees) roof?

Hello. I'm in the design phase of my home in Iowa and have wondered, if I install solar panels its there a certain pitch roof that would be best? Or as long as the roof is walk-able like a 5:12 pitch, I should be fine in the future?

Thanks
