The point is, hot-dipped galvanized nails will do the job for 99% of the houses out there. I'd only specify stainless roofing nails if I lived at or close to the ocean. Hot-dipped galvanized nails can last well over 100 years in non-oceanic climates.he point is, hot-dipped galvanized nails will do the job for 99% of the houses out there.

Costs more to build out. As you said, there are all kinds of other factors, but the same square footage in two stories will cost less to build than in one. Most homes with traditional foundations can sustain a second floor addition without additional support.
With a two story home, you can only grow finished square footage by approximately 1/3 when you finish the lower level. Thatâs the difference. 3. Structure â the majority of the cost of a home is in the structure. Simplify the structure and you lower the cost per square foot of a home. We once built a 2,400 square foot home that had $15,000 trusses, whereas most of the 2,400 square foot homes we build have trusses of $9,000. Comparing the same homes again, the windows in the more expensive home cost $32,000. The other home had $11,000 worth of windows. Therefore, two homes with the same square footage and one has $27,000 more cost in just two components of the home.
