Normalize the basic project
Living-area square footage is not roof area. Pitch, waste, dormers, valleys, walls, chimneys, skylights, height, access, staging, and landscaping protection can materially change the work.
Line items every estimate should clarify
- Manufacturer, product line, profile, and color
- Tear-off, disposal, and number of assumed layers
- Deck replacement allowance or unit price
- Eave protection, underlayment, starter, ridge, and ventilation
- Chimney, skylight, wall, valley, and penetration flashing
- Gutters, snow retention, solar, and other accessory coordination
- Property protection, magnetic cleanup, and final inspection
- Payment schedule, exclusions, and written change orders
Compare the companies as well as the products
Verify the business identity, applicable Vermont registration, insurance, relevant system experience, who supervises the work, who will perform it, and how service or warranty questions are handled.
Ask for current documents rather than relying on a logo, badge, or verbal assurance. Understand manufacturer coverage separately from contractor workmanship coverage.
Use questions to expose assumptions
Ask each company what could change the price, what remains hidden, whether the same crew installs the proposed system regularly, and what is specifically excluded. A clear answer is often more valuable than a proposal padded with generic marketing language.
Beware of allowances that hide the likely total
Allowances are useful for genuinely concealed conditions, but they should use a clear unit and realistic basis. An unusually low allowance can make the starting total look attractive while shifting predictable cost into later changes.
Ask how often the company encounters additional decking or flashing work on similar buildings and how you will see and approve the condition before it is covered.
A fair comparison process
- Create one list of roof sections and accessories
- Mark each proposal included, excluded, allowance, or unclear
- Ask all companies the same clarification questions
- Verify current business and insurance documents
- Separate payment terms from total price
- Compare workmanship coverage and service process
- Do not choose until material differences are understood
Line the two documents up before comparing totals
| Line | What to compare | Why totals move |
|---|---|---|
| Measured roof area | Squares, and how measured | Satellite measurement misses planes and additions |
| Layers and tear-off | How many layers, and whether all come off | A layer-over hides the deck and changes the project |
| Deck allowance | Included quantity and unit price beyond it | The largest source of change orders |
| Ice protection | How far up from the eave, and in valleys | A genuine performance difference in this climate |
| Underlayment | Type across the field | Cheap to downgrade, invisible once covered |
| Flashing | New step flashing, or reused | Reused flashing is where a new roof leaks first |
| Ventilation | Intake and exhaust as a designed pair | Exhaust without intake worsens attic moisture |
| Disposal and protection | Dumpster, landscaping, magnet sweep, permits | Excluded items reappear as cost or as your problem |
| Warranty | Manufacturer system versus installer workmanship | Different durations, exclusions and issuers |
What a low number usually means
It is rarely a scam. Far more often a lower price reflects a thinner scope: fewer squares measured, ice protection at the minimum rather than past the wall line, reused step flashing, no decking allowance, standard underlayment, disposal treated as an extra. Each is a defensible choice as long as you know you are making it.
The version worth walking away from is the one that will not put scope in writing. For residential work at or above $10,000, Vermont requires the contract to state a price provision, estimated start and completion dates, a description of services and materials, and a signed change-order process. A company declining to describe scope is declining something you are entitled to.
