Step-by-Step Guide to Writing a Roofing Estimate
Creating a detailed, accurate roofing estimate is one of the most important skills for a contractor. A well-written estimate helps to ensure you’re fairly compensated for your work and sets the stage for a smooth insurance supplement process. In this guide, we’ll walk through the key steps to writing a professional roofing estimate that will help you protect your bottom line.
What Do You Need to Include in a Roofing Estimate?
A roofing estimate should include all the details necessary to provide a complete picture of the project’s scope and cost. Here’s what to cover:
A breakdown of materials, labor, and additional costs like overhead and profit (O&P).
Specific references to building codes or regulations that apply.
Accurate measurements and quantities for all project components.
When Do Contractors Need a Roofing Estimate?
Roofing estimates are typically needed in these scenarios:
Before Adjuster Meetings: Prepare an estimate to present the full scope of work to the insurance adjuster.
Retail Projects: Provide a cost outline for homeowners paying for the work themselves.
Competitive Bidding: Submit estimates to compete for a project, showcasing your proposed costs and services.
While these scenarios differ, the steps for creating a professional estimate remain the same and they often overlap with the processes used for supplement writing.
Estimate Process Step-by-Step
Step 1: Collect Essential Project Information
Before starting your estimate, gather all the relevant details, including:
Roof Measurements: Use tools like EagleView or Hover to calculate the roof’s total area, pitch, and other key dimensions.
Damage Assessment: Document visible and hidden damages, including photos and descriptions.
Code Requirements: Research local building codes to ensure your estimate aligns with any mandated upgrades or materials.

Step 2: Break Down the Costs
1. Materials
List all materials required for the project (e.g., shingles, underlayment, flashing).
Include quantities and prices, ensuring you account for waste percentages.
Example: "30 squares of shingles, including 10% waste margin."
2. Labor
Provide hourly or project-based labor rates.
Specify the number of workers and estimated hours needed.
3. Overhead and Profit (O&P)
Add O&P to cover operational costs and ensure profitability. While 10% for overhead and 10% for profit is common, percentages can vary depending on location and insurance company guidelines.

Step 3: Use Tools Like Xactimate for Accuracy
Leveraging estimating software like Xactimate can streamline the process and ensure consistency. It allows you to:
Generate itemized estimates quickly.
Include region-specific costs and code upgrades automatically.
Save templates for future projects.
Step 4: Include Supporting Documentation
Supplement your estimate with detailed documentation to justify your scope of work:
Photos of damages with notes on context.
References to building codes or manufacturer specifications.
Receipts or quotes for materials to verify pricing.
Step 5: Present the Estimate to Stakeholders
Once your estimate is complete, it’s time to share it with the relevant party:
For Adjuster Meetings: Present your estimate to insurance adjusters to establish a clear scope of work.
For Homeowners: Provide the estimate as part of your proposal for out-of-pocket projects.
For Project Bids: Submit the estimate to showcase your approach and value compared to competitors.
Common Mistakes to Avoid in Roofing Estimates
1. Underestimating Costs
Failing to account for all project components, such as waste percentages, permits, or upgrades, can result in lower payouts.
Solution: Use tools like Xactimate to ensure accurate estimates.
2. Missing Code Requirements
Overlooking required upgrades can lead to compliance issues and out-of-pocket expenses.
Solution: Research and include state-specific building codes.

3. Incomplete Documentation
An estimate without proper documentation is less likely to be approved.
Solution: Always attach supporting photos, measurements, and references.
