How to write a roof repair estimate for a defined repair area

Write a localized roof repair estimate with clear area units, material allowances and flashing scope. Includes an itemized PDF example.

THE SHORT ANSWER

A roof repair estimate should price a defined, inspected repair area and explain its limits. Identify materials, access, flashing work and concealed-condition assumptions without presenting a localized repair as a whole-roof guarantee.

The worked project in this guide is localized shingle repair. It uses an original fictional job to explain the estimating decisions, with a matching roof repair PDF example. Replace the example inputs with your measurements, supplier quotes and labor costs.

1. Describe the repair location

Identify the roof section and the problem the scoped work addresses. Keep inspection observations and the proposed repair distinct. A customer should be able to understand why these components appear in the estimate rather than seeing only a generic roof repair charge.

2. Explain roofing measurement units

A roofing square represents 100 square feet of area. This example repairs 100 square feet but allows 1.2 squares of replacement shingles. The purchase allowance must be checked against the actual product, pattern and repair extent.

3. Scope the flashing work

Name the included flashing task and its location instead of suggesting that every penetration is covered. If investigation reveals a different source of water entry, revise the repair plan and estimate before extending work beyond the original scope.

4. Clarify concealed conditions and access

List what happens if damaged decking or a larger affected area is found. Access arrangements and site protection also belong in the estimate. Have qualified personnel assess the actual roof; this pricing example is not a roof-work procedure.

A worked roof repair calculation

The material allowance is 1.2 roofing squares × $140 = $168. Installation is 100 sq. ft. × $3.50 = $350; one uses a purchasing quantity and the other the scoped repair area.

The complete example contains 7 lines totaling $1,293.00 before any tax or markup. These are deliberately stated example prices, not a survey, regional price recommendation or offer to perform the job.

To set your own selling price, review direct costs and decide how you will cover overhead and profit. For example, adding 20% to a $1,000 cost gives $1,200; it does not produce a 20% gross margin. Use the approach you intend consistently, and avoid adding a second markup to rates that already include it.

Before you send the estimate

  • Identify the inspected repair area.
  • Specify product and appearance assumptions.
  • Name the included flashing task.
  • Explain how concealed damage changes the estimate.

Example scope boundary: No whole-roof replacement, decking replacement, structural repairs, hazardous-material handling or guarantee of conditions outside the inspected repair scope.

Review the client name, location, validity date and all calculations. Tax is not included in this example; determine the correct treatment for the actual work rather than copying a sample percentage.

Common questions

What is a roofing square in an estimate?

It is an area unit equal to 100 square feet. Label it clearly so it is not confused with one square foot or one bundle of shingles.

Can a small roof repair estimate include decking replacement?

Include it only when assessed and quantified, or label it as a separate allowance. Do not imply unknown decking damage is covered by a surface repair price.
