A roof replacement starts with planning. Written scope and clear assumptions reduce the chance that one bid looks cheaper simply because it leaves out work.
Establish your planning range
Estimate roof area and use the Roof Replacement Cost Calculator before requesting bids.
Request itemized scope
Ask for tear-off, disposal, underlayment, flashing, drip edge, ventilation, roofing material, fasteners, cleanup and permits to be identified.
Clarify decking repairs
Ask how damaged decking will be charged and whether the bid includes an allowance.
Confirm product and warranty details
Get exact manufacturer and product line names. Separate material warranty from contractor workmanship warranty.
Discuss jobsite logistics
Confirm delivery, dumpster placement, landscaping protection, access, weather delays and cleanup.
Compare the same scope
Use the roofing quote comparison guide before selecting a bid.
