Cost of New Roof

[Kevin C.]

Buying a Multi- Family house.  Roof needs to be replaced.  I believe there is a wooden roof underneath and they put Asphalt over it..(lovely).  House has 2 small dormers and its dimensions are 28 X 48…..Roof has 4 slants ..if that makes sense  …(front- back and 2 sides are longer )  I assume I have to take it down to the plywood..etc…  +  Gutters…. 

Trying to get a Guesstimate?

Thanks
