Default post question

I added a 4 x 18 deck to an existing screened porch that's been attached to my house for many years. I used three 16x16x10 cement blocks in the corners and center on which the new double 2x6 sill plate now rides, then attached decking board "extensions" to the new deck and attached the "new deck" to the existing porch plate, making one larger area. The new roof section will be covered with polycarbonate rather then continuing the roof shingles that cover the porch.

The cement blocks are pounded into dirt, there's no gravel under them. My question is, I live in the northeast...should I expect the blocks to shift much in winter despite their weight?

Thanks very much, Ken

Yes, the frost will push them up, and possibly loosen the conection to the house.
You need to dig down to what is called the frost line. About 4 feet down in your area.
A local building official will let you know your depth and size of the concrete peirs you will need.
Good luck.

They need to be as deep as the footings in a none basement house in your area.
