Job costing for roofing contractors
Roofing margin is sensitive to waste factor, tear-off surprises and dump fees that rarely match the original estimate exactly. Jobsheet lets you log actual material and labor cost as the job progresses so you catch a bad waste estimate before the crew moves to the next roof.
Waste factor is a guess until the material is actually ordered
Bids use an estimated waste percentage, but actual bundle counts depend on roof complexity discovered on tear-off. Logging the real material order against the job shows immediately whether your waste factor assumption was right.
Dump and disposal fees vary by job and by season
Tear-off debris disposal costs vary with roof size, layers, and local dump pricing, and are easy to underbid on multi-layer tear-offs. Track dump fees as their own expense category so you can see the real average per square before your next bid.
Weather delays turn into crew idle-time cost
A rained-out day doesn't stop crew cost if you're paying a day rate or the crew shifts to a different job. Logging labor hours against the specific job — even on a delayed one — keeps the job's actual cost accurate instead of hidden in overhead.
What to track on every roofing job
- Shingles or membrane and underlayment
- Flashing, vents and fasteners
- Dump and disposal fees
- Crew labor by day or by square
- Permits (where required)
- Subcontracted crews on larger jobs
Frequently asked questions
Can I track cost per square instead of per job total?
Jobsheet tracks total expected vs. actual cost per job. Many roofers use the job notes and category totals to work out a per-square figure once the job closes.
What happens to the budget if a job gets re-scoped after tear-off?
Update the job's expected cost to reflect the new scope, then keep logging actual expenses — the projected final cost recalculates from there.
