Metal roofing is premium, but many quotes are not apples to apples. Two estimates can look similar on price per square and still be completely different systems once you account for underlayment layers, ventilation, closures, flashings, fasteners, and the small parts that prevent leaks.

What a complete metal roof system actually includes
Use this as the baseline when comparing quotes. If a line item is missing, the system is incomplete, even if the panels are high quality.
- Roof deck readiness and prep
- Underlayment stack matched to pitch and climate
- Ice and water protection where required
- Ventilation plan (intake and exhaust) sized correctly
- Panels or stone coated system (matched to slope and details)
- Ridge, hip, and transition details
- Eave, rake, and drip edge details
- Valley and wall transition components
- Penetration detailing (vents, skylights, chimneys)
- Closures, sealants, tapes, and fastener types
- Snow management where applicable
- Delivery plan for long panels and accessory parts
Why cheaper quotes are often missing the parts that matter
Most quote gaps come from one of three places:
- Accessories treated as optional (closures, boots, specialized flashings, correct fastener mix).
- No ventilation math (ridge vent added without soffit intake, or intake blocked later by insulation).
- No complete takeoff (no verified bill of materials, so parts get discovered mid install).
Step by step: how to compare metal roofing quotes the right way
Step 1: standardize the roof type you are pricing
Before you compare numbers, confirm you are comparing the same category:
If you are still deciding, browse the full catalog first: All metal roofing systems.
Step 2: build a bill of materials before you judge price
A quote that does not trace back to a takeoff is a guess. Use the takeoff worksheet to build your baseline materials list, then compare who included what.

Step 3: validate ventilation so condensation and ice dams do not become your problem
Ventilation is a system. Exhaust without intake is a problem, and intake without exhaust is a problem. If your quote includes ridge vent, it must also include adequate soffit intake and a clear airflow path.

Step 4: verify delivery readiness and timing
Long panels, ridge components, and small accessories can bottleneck an install if they arrive late or are missing. Make sure your order plan matches delivery realities.

Step 5: use a Roof System Audit to find missing line items before checkout
If you want a second set of expert eyes to confirm your materials list, details, and ordering completeness, use the audit page and bring your best quote plus your roof info.
Quick quote comparison checklist
- Does the quote include a complete bill of materials tied to your roof plan?
- Are underlayment layers specified by type, not generic wording?
- Is ventilation sized and balanced, not just mentioned?
- Are closures and small parts explicitly listed?
- Are penetrations and transitions accounted for, not assumed?
- Does the delivery plan match your timeline and panel length needs?
Common questions
Do I need a Roof System Audit if I already have a contractor?
If you are supply only, the safest move is to confirm the materials list is complete before ordering. Many install delays come from missing small parts, not the main roof material.
What if I do not have perfect measurements yet?
Start with the takeoff worksheet and what you do know. Then use the audit or consultation to confirm what is still needed.
Where do I find answers to ordering and product questions?
