The challenge here was the entry porch that we removed was over a poured concrete steps. Which made the surface too high and interfered with the door, in particular the storm door. So before we could rebuild we had to take out 12″ of the concrete steps. Which when we removed the concrete we found the rim board behind the concrete badly deteriorated. So we cut out and replaced a section of rim board before flashing and attaching the deck. All good for many years.
