Roof Quote Scope Comparer — Compare Bids Line by Line

Compare Roof Replacement Quotes Scope by Scope

This private worksheet helps you compare roof replacement bids line by line. Enter each contractor’s scope details—measurements, materials, tear-off, decking, flashing, ventilation, permits, and cleanup—to see differences clearly. It does not rank contractors or predict final costs. Use it alongside in-person estimates and ask every bidder to explain any line that varies significantly. Professional review is required before publication.

Quick, low-risk steps

Gather at least two written, itemized quotes from licensed contractors.

Open this worksheet in a private space—no data is saved or shared.

Enter each quote’s measured roof area, pitch, and material specifications.

Check that every quote includes tear-off, decking allowance, underlayment, flashing, and ventilation.

Compare permit, inspection, site protection, and cleanup line items.

Note any missing items or vague language and ask the contractor to clarify in writing.

How the Scope Comparer Works

The comparer is a side-by-side checklist, not a calculator. You fill in what each contractor included—or left out—so you can see differences at a glance. It covers the major scope items that affect price and quality: roof measurement, tear-off, decking, underlayment, flashing, ventilation, material system, permits, site protection, and warranty terms.

Because every roof and quote is different, the worksheet does not assign scores or tell you which bid is “better.” It simply organizes the facts you collect. Use it before you sign a contract to confirm that all bids address the same work. If a line is blank or unclear, ask the contractor to explain.

Enter each contractor’s name and license number at the top.
Fill in the measured roof area and pitch from each quote.
Check off included items: tear-off, decking replacement allowance, underlayment type, ice and water barrier, flashing, vents.
Note the shingle or metal brand, series, and warranty length.
Record permit and inspection handling, site protection, and cleanup details.

Key Scope Items to Compare

Roof measurement is the foundation. If two quotes show different square footage, ask why. A small difference can change material and labor costs. Tear-off and disposal should be explicit; some bids bury a “layover” option that leaves old shingles in place, which may hide decking damage and shorten the new roof’s life.

Decking allowance is often a per-sheet price for any rotted wood found after tear-off. Without it, you could face a surprise change order. Underlayment and leak barrier choices matter for Atlanta’s rain and occasional ice. Flashing around chimneys, skylights, and walls must be replaced, not reused. Ventilation upgrades may be required by code and affect shingle warranty.

Compare measured area and pitch: are they within 5%?
Check that tear-off includes full removal and dumpster/hauling.
Look for a decking allowance per sheet, not a vague “as needed.”
Verify underlayment type (synthetic vs. felt) and ice/water barrier placement.
Confirm flashing is new metal, not resealed old flashing.

Permits, Inspections, and Code Compliance

In Atlanta, most roof replacements require a permit. The contractor should pull the permit and schedule inspections. If a bid excludes permits, you may be responsible for obtaining them, which can delay the project and add cost. The comparer has a field to note who handles permits and whether the price includes the permit fee.

Code compliance goes beyond permits. Atlanta has adopted the International Residential Code with local amendments. Your contractor should know the current wind, nailing, and ventilation requirements. Ask if the quote includes any needed upgrades to meet code, such as additional vents or high-wind shingle installation methods.

Record who pulls the permit: contractor or homeowner.
Check if the permit fee is included in the quote.
Ask about required inspections: rough-in and final.
Note any code-upgrade line items, such as ventilation or nailing pattern.
Verify the contractor’s license and insurance before entering data.

Warranty, Change Orders, and Final Check

Warranties come in two parts: manufacturer’s material warranty and contractor’s workmanship warranty. The comparer lets you note the length and coverage of each. A long material warranty may require specific installation practices; if the contractor doesn’t follow them, the warranty could be void.

Change-order terms are critical. A quote that seems low may allow the contractor to add charges for unexpected decking, code upgrades, or disposal fees. The worksheet includes a field for change-order policy. Before you sign, make sure you understand how changes are priced and approved. After filling in all fields, review for missing items and ask for written clarification on any gaps.

List manufacturer warranty: years, coverage, and transferability.
List workmanship warranty: years and what it covers.
Note change-order policy: written approval required? markup percentage?
Check for hidden exclusions like disposal overage, permit expediting, or weekend work.
Use the completed worksheet to ask each contractor targeted questions.

What homeowners ask next

Can this tool tell me which quote is the best deal?

No. The comparer organizes scope details so you can spot differences, but it does not rank quotes or calculate value. The “best” quote depends on your priorities, the contractor’s reputation, and the completeness of the scope. Use the worksheet to ask informed questions, then decide based on the full picture.

What if a contractor won’t provide an itemized quote?

A reputable contractor should be willing to break down the scope. If a bid is a single lump sum with no details, you cannot compare it fairly. Ask for a written, line-item estimate. If they refuse, consider it a red flag and seek other bids.

Is my data saved when I use this worksheet?

No. This is a private, on-page tool. Nothing you type is stored, transmitted, or shared. You can print or screenshot the completed worksheet for your records, but the site does not retain any information.
