Why Roofing (Commercial) Contractors Bleed on Warranty Squares

QUICK ANSWER

Commercial roofing contractors bleed on warranty squares when callback work has no cost code, tear-off and new install get billed as one scope, and production per square never gets measured against the bid. CONTROL separates the scopes, tracks squares per crew day, and makes warranty cost a number you manage.

Square-Based Production Tracking

Squares per crew day is the production number of the trade. Tracked weekly against the bid, it shows a slow roof while there is still time to fix it.

Tear-Off vs New Install Billing

Tear-off carries disposal, surprises, and weather exposure that new install does not. Separate scopes and separate billing keep the demo from eating the install.

Warranty Work Cost Separation

Warranty callbacks are real labor and material spent years after the revenue. A warranty cost code per job shows which systems, crews, and details keep coming back.

QUESTIONS ROOFING (COMMERCIAL) CONTRACTORS ASK

Why do commercial roofing contractors lose money on warranty work?

Commercial roofing contractors lose money on warranty work because it has no cost code and no budget. Callbacks hit years after the job closed, get charged to overhead, and never trace back to the crew, detail, or system that caused them. A warranty code per job turns callbacks into a quality report you can act on.

How should a roofing contractor bill tear-off work?

A roofing contractor should bill tear-off as its own scope with its own schedule of values line, funded as the demolition happens. Chapter 6 of CONTROL structures the SOV and billing dates, so disposal fees and deck surprises get paid by the project in month one instead of floating on your credit line.

What profit margin should a commercial roofing contractor target?

A commercial roofing contractor should target 22 to 30% gross profit per project and 12% net profit after all expenses, with overhead between 9 and 13%, with warranty reserves inside the job costs. If callbacks live in overhead, your real margin is lower than any report shows.
