Give every bidder the same project brief.
Describe the same roof problem, included buildings and desired result to each business. If one receives a request for the main roof and another hears “all roofing,” their totals may be answering different questions. Share the same available records and access restrictions.
List your unresolved choices separately. For example, ask for the proposed base covering and a separate alternative instead of letting every contractor assume a different material. The CSLB recommends comparing written bids based on matching plans, specifications and scope.
Build a line-by-line comparison.
Use a simple sheet with one column per proposal. Add rows for roof sections, removal, covering, underlayment, flashing, vents, deck repairs, disposal and inspections. Write “not stated” when an estimate leaves something unclear. Do not treat silence as inclusion.
Ask the contractor to fill the gaps in writing. You are looking for an answer you can rely on later, not an argument about whose proposal looks more polished. A short clarification can reveal that two prices were much closer than they first appeared.
Separate allowances from fixed scope.
An allowance is a planning amount, not a description of completed work. Ask what quantity or condition it assumes and what happens when the actual finding differs. If concealed wood repairs are priced by unit, identify that unit and what the unit price includes.
Check whether extra work requires your approval before proceeding and how supporting photos or measurements will be shared. Keep that procedure with the proposal so a change discovered after removal follows an agreed path rather than a rushed phone conversation.
Compare the working arrangement.
Who answers questions during the project? Who can authorize a change on your side? How will inspection delays or material substitutions be communicated? These details matter when you are arranging vehicles, pets, tenants or time away from work.
Read proposed start and completion terms along with the work scope. A date that depends on an unresolved permit or product order is different from an agreed work window. Ask which parts of the schedule remain open and when you will receive an update.
Keep the decision in plain language.
Before choosing, write one sentence explaining why a proposal fits: the roof sections match your needs, the materials are named and the remaining uncertainty has a process. If your reason is only “the number was lower,” you may still have unanswered scope questions.

Questions before the next step
Should I accept the lowest roofing estimate?
Price matters, but compare the included work before deciding. A lower total may reflect a different material, omitted section or task assigned to the owner. Ask for those differences to be explained in writing.
Can I compare a repair quote with a replacement quote?
They describe different outcomes. Review what the repair addresses and what roof remains, then compare that result with the replacement scope. The totals alone are not a like-for-like comparison.
