i mean there's the removal of the OG roof

and the layering/application of the new roof

i'm assuming this is a single family home so there's probably like roofing shingles which could be why it's so much?

20 g is what you'd see on a small apt bldg roof in NYC but you don't have all that decorative stuff to worry about and it's $$ b/c of the scaffolding/permitting. depending on the building that is a smaller area than a single family home so i can see why a single family may be more (that and the shingling)

im doing a number of replacements now and per building it averages out to about 26 per bldg
