How Much Does A New Roof Cost?
- Factor 8: Is your roof busy? What I mean by this is, does
your roof have a lot of “stuff” on it? Having to roof around
skylights, air conditioners, pipes, exhaust fans, etc. will add a
little to the cost of the roof because it requires additional labor
- Factor 9: Is your roof cut-up? Are there a lot of hips and
valleys? Are there dormers? Roofing a bunch of hips, valleys, and
dormers adds to roof cost.
- Factor 10: What type of roof deck do you have? You know
what a roof deck is. It’s the structural element your roof is
installed over. For most residential homes, it’s plywood or OSB and
pretty straight forward. For commercial roofing, deck types are
steel, concrete, light weight insulating concrete, gypsum, cement
fiber, and probably a few others I can’t think of right now. Varying
deck types create varying roof costs.
- Factor 11: How tall is the building? If the building is two
stories, there’s typically not much change in roof price from that
of a one-story building. But the higher you go from there, the more
the cost goes up because you have to have special equipment and
added labor to get the material up on the roof.
- Factor 12: How accessible is the roof? If a roofer can back
up into your driveway with a truck, tear off the roof and throw the
materials into the truck, and also load the roof with new materials
from the driveway, it’s called good access. But, there are some
buildings or homes that don’t have good access, and the roofing
materials have to be torn off and carried over to a dumpster, truck,
or trailer. This is commonly referred to as “double-handling” the
material, and it will drive the cost of a new roof up. I’ve had to
triple handle material from time to time where you tear off a roof,
raise it up to a different roof level, carry it over to the edge of
the roof, then throw it off and carry it to a dumpster. It greatly
slows down the roofing process.
- Factor 13: Are there parapet walls? Many commercial roofs,
and a lot of flat residential roofs, have parapet walls, which are a
raised wall at the perimeter of the roof, and can be anywhere from
one foot to 15’ high or so. Many of these walls require some type of
roofing material to be installed on them, thereby adding labor and
material to the job, and costing more than if the roof edge were
- Factor 14: Is there a lot of landscaping around the
building? No building owner wants their flowers or bushes messed up,
so roofers often have to take extra precautions protect plants
around a building. This is often a minor cost, depending on how much
landscaping there is, and often isn’t even an add to the roof price.
Roofers just consider it part of doing business.
- Factor 15: Where is the building located geographically?
Roofs in New York City are going to cost more than roofs in Wichita,
