Support for new porch roof
I am adding a porch roof to the front of my house. It will extend past the existing roof edge 8 ft and run the entire length of my house (approx. 53′). I am planning to place the posts 81″ on center. Currently I have a concrete slab in front of my house that is 4″ deep and extends 10 ft from the front of the house. Will this be sufficient to support the weight or do I need to cut out the concrete and dig down below the frost line like I would do for a deck? Thank you in advance.
