Contractor Quote Worksheet for Roof Replacement (Asphalt)
Use this checklist when comparing bids. The cheapest quote is not always the lowest final cost; the bid that defines scope, allowances, permits, cleanup, and change-order rules usually gives the cleaner budget.
| Bid line | What to ask | Why it matters |
|---|---|---|
| Scope definition | Confirm what is included in the roof replacement (asphalt) base bid and what is priced as an allowance or option. | Vague scope turns into change orders after demolition or material selection. |
| Labor assumptions | Labor is about 40% of the mid-range budget. Ask whether demo, prep, cleanup, disposal, and final punch-list time are included. | A low bid may exclude prep work, disposal, or return trips. |
| Material allowances | Materials are about 60% of the budget. Get brand, grade, finish, and quantity assumptions in writing. | Allowance bids look cheap until fixtures, finishes, or delivery fees are upgraded. |
| Permit and inspection plan | Confirm who pulls permits, who pays fees, and when inspections happen. | Permit gaps can delay final payment, insurance claims, or home resale. |
| Timeline and disruption | The normal timeline is 2-4 days. Ask what happens if materials arrive late or hidden conditions are discovered. | A fast verbal timeline without milestones is hard to enforce. |

Asphalt Roof Tear-Off, Underlayment, and Flashing Audit
Asphalt shingle roof pricing should explain more than bundle count. The bid should identify roof squares, tear-off layers, deck repair unit prices, underlayment system, flashing, ventilation, waste, and warranty registration.
Scope checks
- 1Confirm shingle type, roof squares, starter, ridge cap, synthetic or felt underlayment, ice/water membrane, drip edge, valley detail, and pipe boots.
- 2Ask for decking replacement price per sheet or linear foot before tear-off begins.
- 3Verify attic ventilation, nail pattern, disposal, landscaping protection, permit, inspection, and workmanship warranty.
Quote traps
- Low bid that reuses flashing, skips drip edge, omits ice/water membrane, or leaves ventilation unaddressed.
- No written deck replacement unit price.
- Warranty that depends on installation details not listed in the proposal.
Proof to collect
- ✓Product and accessory list matching the installed shingle warranty requirements.
- ✓Deck, underlayment, flashing, valley, and penetration photos before final coverage.
- ✓Final invoice with warranty registration and cleanup confirmation.
