What Is a Roofing Supplement Company — and Why Do You Need One?
A roofing supplement company is a specialized firm that reviews, writes, and submits supplemental claims on behalf of roofing contractors when insurance carriers underpay or omit legitimate line items from a roof replacement or repair estimate. In the insurance restoration industry, the initial carrier estimate is almost never the final number. Adjusters miss items, apply incorrect depreciation, omit code-required upgrades, and skip line items that every experienced contractor knows are mandatory for a quality repair.
That's where a professional roofing supplement company steps in. The Estimate Company was built by Licensed Insurance Adjusters (LIAs) who spent years on the carrier side before switching to advocate for contractors. We know exactly how adjusters think, what software they use (Xactimate), and more importantly — we know what they're trained to skip.
Why Licensed Insurance Adjusters Make All the Difference
Most roofing supplement companies are run by contractors, virtual assistants, or offshore teams who have learned to copy-paste Xactimate line items. The problem? They don't understand the reasoning behind each code, the carrier-specific guidelines, or how to write a compelling supplement letter that survives a reinspection.
Licensed Insurance Adjusters hold state-issued licenses and are trained in policy interpretation, coverage analysis, and claims writing. When a supplement from The Estimate Company lands on a carrier's desk, it arrives with professional credibility that generic services simply cannot match. Our adjusters have worked with over 50 insurance carriers including Allstate, State Farm, Farmers, Travelers, Liberty Mutual, and regional carriers across the Southeast and beyond.
The result: fewer denials, faster approvals, and higher average recovery per claim.
The Real Xactimate Line Items Carriers Skip Every Time
If your carrier estimate doesn't include all of the following line items, you're leaving real money on the table. A professional roofing supplement company should know every one of these codes by heart:
- RFG/ARMV — Remove and replace ridge cap. Frequently omitted or underquantified. Required on virtually every shingle replacement.
- RFG/ASTR — Starter shingles. Carriers routinely exclude this, yet it's a code requirement under IRC and manufacturer installation specs.
- RFG/IWS — Ice and water shield. Coverage requirements vary by state and local code, but adjusters default to minimum coverage even when full-slope or extended coverage is required.
- RFG/DRIP — Drip edge. Eave and rake drip edge are separate line items. Both are required under current building codes, but carriers commonly bundle or omit them entirely.
- RFG/STEP — Step flashing. If your roof has any wall intersections, step flashing is mandatory. It's regularly missed or grossly underestimated.
- RFG/HIGH — High roof (steep or high-access) loading factor. Anything over 7/12 pitch requires an additional labor factor. Adjusters often apply flat rates regardless of pitch.
- RFG/FELTSU — Synthetic underlayment. If code or manufacturer requirements call for synthetic felt (and they typically do), this line item must appear separately at the correct price point — not blended into base pricing.
These seven line items alone represent hundreds to thousands of dollars per claim. Multiply that across a contractor's monthly volume and the math becomes clear: every job without a professional supplement is a job with money left behind.
What the Roofing Supplement Process Looks Like
When you partner with The Estimate Company as your dedicated roofing supplement company, here's exactly what happens:
- You submit your claim documents — carrier estimate, scope of loss, photos, and any correspondence. We handle the rest.
- Our Licensed Insurance Adjusters review the scope — comparing it to code requirements, manufacturer installation specs, and local building requirements for your state.
- We build the supplement in Xactimate — using proper codes, accurate quantities, and current pricing from the Xactimate price list for your region.
- We write and submit the supplement letter — professionally drafted with code citations, photo references, and carrier-specific language that gets results.
- We follow up with the carrier — until the supplement is approved or we've exhausted all avenues of recovery.
From submission to approval, most supplements close within 5–15 business days depending on carrier and complexity.
