Roofing estimates that actually cover your day
Roofing jobs live and die on tear-off, underlayment, and disposal — the line items estimators skip that eat every bit of profit. Bid Buddy walks you through the whole roof so nothing lands on your dime.

Squares & pitch
Steeper pitches mean slower work and more safety setup. Price labor per square by pitch, not a flat rate.
Tear-off & disposal
Layers, dump fees, and haul-off can be 15–25% of a re-roof. Line-item it — never bury it in 'materials'.
Underlayment & flashing
Ice-and-water, drip edge, step flashing, boots — pennies per sq ft that add real dollars on a full roof.
Warranty & callbacks
Bake a 2–4% callback reserve into every bid. One leak visit erases the profit on a small job.
Markup & margin for roofing
Most independent roofers need a 35–50% markup on shingle work to net a real 20–25% margin after overhead, warranty, and callbacks. Metal and flat roofs typically justify higher markup because of specialty labor.
Line items to include in every roofing bid
- Tear-off (per layer, per square)
- Dumpster & disposal
- Shingles / metal panels / membrane
- Underlayment (synthetic + ice & water)
- Drip edge, ridge vent, pipe boots
- Step & counter flashing
- Labor (by pitch)
