Compare the full reroof plan, not one total at the bottom

A roof replacement bid should explain tear-off, rebuilding, and hidden conditions.

Compare reroof bids with clear tear-off limits, hidden-decking allowances, protection details, and a written change process.

Decisions before work starts

Whole reroof bid structure, tear-off, hidden decking, and change control

Whole-roof replacement involves more than the finished surface. Owners need to understand removal limits, deck evaluation, transitions, penetrations, drainage details, material assumptions, site protection, and the process for hidden findings. This independent bid-planning resource helps organize those questions before proposals are compared. It does not recommend a system for a specific building or state that replacement is required. A qualified contractor must inspect the property and develop the actual scope. Keep product choices, quantities, approvals, and revisions in the project record.

01

What is being removed?

Compare included roof areas, layers, attached components, disposal, and the conditions assumed beneath them.

02

How is decking handled?

Define inspection, documentation, unit pricing or allowances, approval authority, and replacement records before tear-off.

03

Which details are rebuilt?

List walls, edges, valleys, penetrations, drains, and equipment interfaces rather than relying on “complete roof.”

04

How do changes move?

Require written condition evidence, price or time impact, approval, and updated closeout documents.

Pitched roof assembly: define every layer and edge

Use the numbered layers to compare a proposed scope with the conditions found during inspection or opening.

  1. Roof covering

    Identify the existing and proposed covering, repair boundary, and tie-in to material that remains.

  2. Underlayment

    Keep a continuous water-shedding path through laps, valleys, walls, penetrations, and other transitions.

  3. Deck or substrate

    Record exposed condition and define the approval process for concealed repair or replacement.

  4. System attachment

    Use the manufacturer-approved attachment for the actual covering and site conditions; this drawing gives no pattern or quantity.

  5. Edge flashing and fascia

    Review edge metal, drainage discharge, and fascia condition before the new covering closes the assembly.

Choose a Roof Type by the Whole Assembly, Not the Sample Board

Compare slope, deck, drainage, ventilation, flashing, access, and maintenance before selecting a covering.

A useful first conversation

Bring observations.
Ask for a defined scope.

Use this site's checklist to organize the facts you can safely collect. The roof assembly, concealed condition, and repair limits need a qualified professional's review.

Mark every roof area included and excluded from the replacement.

List assumed removal layers, hauling, disposal, and temporary protection.

Before you approve

Questions worth asking.

Why can two replacement bids be far apart?

They may assume different removal, deck repair, detail rebuilding, access, protection, materials, and closeout work. Normalize scope before comparing price.

Can decking needs be known before tear-off?

Some conditions may be visible, but other areas remain concealed. The bid should state the process, measurement, evidence, pricing method, and approval for added work.

What should a roof map show?

Included planes, exclusions, transitions, penetrations, drainage points, equipment, and any area priced as an alternate.

Does “complete reroof” define every detail?

No. Ask for the physical actions and boundaries at edges, walls, valleys, penetrations, drainage, and equipment interfaces.

Send the useful views

Contact Austin for an inspection.

Start with a wide photo, a close view of the visible condition, the property city, and the repair history. Stay off the roof and keep clear of wet electrical equipment or damaged ceilings.

In the form, choose Inspection under Service needed and describe the roof condition. A request is for review; it does not confirm an appointment or authorize work.

For more than one picture, text your views and description to 619-912-0486. The form accepts one optional attachment.

When site verification is needed, AWC recommends the $250 Site Evaluation + Written Bid Package. The $250 is credited if the proposed work is approved within 30 days. Confirm the evaluation terms before scheduling.
