Clearances for rooftop solar on a flat roof
![](/app/themes/greenbuildingadvisor/_assets/img/avatar/avatar_50x50.jpg)
Recently Fine Homebuilding had a “Know the Code” article on the requirements for the roof structure for solar panels. It’s here: https://www.finehomebuilding.com/2020/05/05/rules-for-rooftop-solar
It seems everything assumes you have a pitched roof with a ridge. What if you have a flat (or nearly flat) roof? Do you need access to the ridge if you don’t have one?
I’m trying to see what the biggest array I can fit on my roof is.
Thanks.

You must check with your bldg dep. Local fire codes may have different rules, but generally, 36" clearence all around from edge or inside parapets or walls.
