A new roof refers to completely removing the old roofing material down to the deck and installing fresh shingles, which is more expensive but gives you a brand new layer of protection. A replacement often means just layering new shingles over the existing ones, which saves money initially but can hide underlying problems and shorten the lifespan of your roof.
