High-Accuracy Xactimate Roofing Supplements & Estimating Services for Contractors

Carrier scopes often skip drip edge, starter, and steep charges, and your roofing company absorbs the loss. Claim Guard writes roofing supplements that audit every line and recover what the storm truly damaged.

We work as the estimating desk behind your front office, building Xactimate estimates, supplements, and appraisal support for roof claims. Every file uses local pricing and photo proof, and most come back within 48 hours.

Why Chicago Roofs Take a Beating Every Storm Season

The averages 10 to 15 days of damaging hail each year, and suburban Darien saw 4.8-inch stones in March 2026. Straight-line winds, freeze-thaw cycles, and winter ice dams wear down shingles, flashing, vents, and gutters long before their time.
Carriers often call hail hits cosmetic, pay for spot repairs, or leave out ice barrier and drip edge. Most contractors have seen a roof repair cost more than insurance estimate totals allowed. Detailed roofing supplements close that gap with proof.

OUR SERVICES

Roof Supplement Services That Close the Gap in Carrier Scopes

Carrier estimates fall short in different ways. Some miss squares, while others skip code items or steep charges. Our roofing insurance supplements target the gaps contractors and public adjusters see most.

01
We compare the carrier’s Xactimate or Symbolist scope with your photos, line by line. Missing starter, hip and ridge cap, step flashing, and pipe jacks get flagged with clear reasons.
02

Roof Takeoff Services

Our roof takeoff services check Eagle View and Hover reports against your field notes. We confirm squares, pitch, eaves, rakes, and valleys, then apply the right waste factor for each roof.
03

Code Upgrade Documentation

Northern roofs typically need ice barrier reaching 24 inches inside the exterior wall line, plus drip edge at eaves and rakes. Our code citations stop carriers from cutting them.
04

Steep and High Charges

Roofs at 7/12 pitch or steeper, or two stories up, take more time and safety gear. We add steep and high charges, so the estimate’s labor matches the real job.
05

Overhead and Profit Requests

When a job needs a general contractor to coordinate several trades, O&P (overhead and profit) is often owed. We document each trade involved, so the request stands on solid proof.
06
When a supplement stalls, appraisal lets two appraisers and an umpire settle the amount of loss. We build the estimate and photo report your appraiser needs to defend every line.

FAQS

Roof Supplement Questions From Contractors

Here are answers to the questions roofers, contractors, and public adjusters ask us most about supplements.

What is a roofing insurance supplement?

A roofing insurance supplement is a request to add missed or underpriced items to an existing roof claim. Common additions include ice barrier, drip edge, step flashing, starter, and O&P, each backed by photos and current Xactimate pricing.
A roofing supplement company audits the carrier’s estimate, finds missing or underpriced line items, and writes a detailed Xactimate supplement. The best roofing supplement companies also add photo proof, code citations, and written rebuttals when carriers push back.
A roofing supplement can be submitted at any point before the claim closes, as soon as missed damage or costs appear. Many supplements go in after tear-off reveals rotted decking or extra layers, and before the final invoice.
Not every roof claim needs a supplement. A supplement makes sense when the carrier estimate misses real damage, code items, steep charges, or fair local pricing. A quick line-by-line review shows whether the gap is worth sending in.
Only licensed public adjusters and attorneys can negotiate insurance claims for policyholders in Illinois. Roofers and contractors may write estimates, share photos, and discuss damage with the carrier’s adjuster, but cannot legally file or negotiate the homeowner’s claim.
