How Much Does A Roof Cost?

Obviously, our customers want to know the price of a new roof. New roof pricing is based on many factors that are unique to your building. As a result, anyone who gives you ballpark roof prices without inspecting your building’s roofing system is doing you a disservice. Here are some factors that impact roof prices.


 What will go on the roof? membranes, composite, tile, metal,modified bitumen, EPDM, TPO, and Elastomaric all have different price points.


The pitch of a roof can impact the speed of installation. For flat roofs, prices vary for fully adhered, mechanically attached, ballasted, and self-adhering approaches. Tear offs require disposal.


 In addition to the materials you commonly see on a roof, a roof system requires underlayment, screws, flashings, sealants, and possible deck replacement. Roofs may also require insulation depending on “R” value could add costs to a basic roof bids, depending on city and federal codes this might be a requirement.

Ventilation for steep slope:

Steep pitched Roofs desperately need proper ventilation to function properly and to maximize roofing system. Ventilation components can include ridge venting, mushroom vents, power vents, and inlet vents in soffits and gables.

Gutters & Downspouts:

Gutters and downspouts typically have the same lifespan as your roof. And, they are an integral part of how your roof keeps moisture out of your house. Most homeowners have gutters replaced at the same time as the roof.

Roofer's "Speed Bumps":

Does your roof have a lot on it? Things like skylights, air conditioners, pipes, exhaust fans, etc will add a little installation time because each one must be properly sealed. Also, a roof with many hips, valleys, and dormers takes more time and materials to roof than a relatively plain roof.

Roof Heights:

 Single and two-story buildings are common and have typical roofing costs. But when a building gets higher, specialized equipment may be needed, and therefore impacts pricing.

Roof Access:

Can a truck or dumpster be easily placed next to your roof? If not, materials may have to be moved manually, which may add cost.
