Quote the roof.
Explain the work.

1. Define exactly which roofs are included.

Confirm the building and the areas in scope. The main house, garage, porch and additions may use different materials or require different work. Label the roof faces clearly so the customer and crew can tell which areas the estimate covers.

Check the aerial outlines against the available view and flag details that cannot be confirmed remotely. If the imagery is old, obscured or incomplete, record the need for a measurement check before quantities are treated as final.

2. Keep surface area and waste separate.

A roof’s footprint and its sloped surface are different measurements. Pitch affects the surface area being covered, and each face should have its pitch reviewed. Keep units consistent when moving between square feet, square metres and roofing squares.

Waste is an allowance applied to material planning, not additional roof surface. Show it separately so the team can understand and adjust the quantity for the roof shape, material and installation method.

• Review each included face and its pitch.
• Distinguish measured or estimated area from the ordering allowance.
• Keep extras and accessories in their own quantities.
• Confirm final dimensions on site when required.

3. Look beyond the main roof covering.

Shingles or metal panels are only part of a roof estimate. Edges, ridges, hips, valleys, transitions, penetrations and ventilation can introduce separate materials and labor. Treat those details as explicit quantities or scoped allowances.

For metal roofing, distinguish a preliminary layout from a fabrication-ready cutting list. Field dimensions, panel profiles, seams, overlaps, direction and detailing need confirmation before an order is released.

4. Make the product choice understandable.

Name the selected material and the options that affect the quote. A package is most useful when it says what it includes: the roof covering, specified underlayment, relevant accessories, ventilation work and the company’s applicable warranty terms.

If you offer multiple options, explain the difference in scope as well as the difference in price. Avoid letting an attractive package name stand in for a material specification.

5. Write down inclusions, exclusions and unknowns.

State how removal, disposal, property protection, access and cleanup are handled. Existing roof conditions may not be fully visible until work begins. Explain how concealed damage or additional work will be documented and approved if it is discovered.

• Identify the included removal and replacement work.
• Specify known repairs and separately priced extras.
• Explain what remains subject to inspection.
• State the proposal price, tax treatment and payment schedule.
• Use approved agreement wording consistent with the quoted scope.

6. Turn the accepted estimate into a useful job pack.

Keep the selected materials, roof drawing, proposal revision and approved scope with the project. Add verified dimensions, field photos, delivery details and access notes where the crew can find them.

Assign the remaining decisions before work is scheduled. A clear project record should answer what is being installed, where it is going, which details still need confirmation and who owns the next action.
