Full roof replacement

Roof replacement planning for Greater Burlington homes

A useful replacement inspection should explain the system being removed, what can be known before tear-off, what may be discovered beneath it, and how the proposed assembly handles water, snow, and ventilation.

When replacement belongs in the conversation

Short answerReplacement becomes more likely when the roof is near the end of its service life, leaks are recurring, repairs no longer produce a reasonable service life, or the roof assembly has broader installation or substrate problems.

Age alone does not decide the outcome. The roofing company should inspect the covering, flashings, penetrations, transitions, drainage, deck indicators, attic conditions where accessible, and the repair history.

The main cost and scope drivers

  • Measured roof area—not just interior square footage
  • Pitch, height, dormers, valleys, chimneys, skylights, and roof complexity
  • Number of existing layers and disposal requirements
  • Decking repairs discovered after tear-off
  • Material system, underlayment, flashing, ventilation, and snow-retention details
  • Site access, landscaping protection, staging, and cleanup
  • Historic, slate, cedar, lead, or asbestos-related conditions requiring special handling

A replacement proposal should make comparisons possible

Request a project-specific inspection

Tell us about the current roof, visible concerns, property type, town, and intended timing. Those details help a roofing company determine whether it serves the property and handles that type of work.

The decking allowance is where replacement budgets actually move

Short answerDeck condition cannot be fully known until the existing roof is removed, so the proposal should state either an included allowance of replaced sheathing or a written unit price, plus how the quantity is measured and authorized.

Almost every genuine surprise in a roof replacement is beneath the covering. Older Chittenden County housing stock includes plank sheathing, prior layer-overs, repaired sections, and areas softened by long-running leaks around chimneys, valleys and eaves. None of this is visible from the ground or reliably from a satellite measurement.

Two proposals with the same headline scope can behave completely differently here. One may include a set quantity of replacement sheathing and a unit price beyond it; another may leave it undefined and price it after the fact. Ask each bidder the same question — what happens on the day bad decking is found — and compare the answers rather than the totals.

  • How much replacement sheathing is included before extra cost begins
  • The unit price and how the replaced area is measured and evidenced
  • Who authorizes the additional work, and in what written form
  • Whether photographs of the exposed deck are provided before it is covered
  • How plank sheathing, prior layers, or non-standard spacing are handled

What Vermont law already requires in your roofing contract

Short answerA residential contractor performing work estimated at $10,000 or more, including labor and materials, must be registered with the Vermont Office of Professional Regulation, and the written contract must state a price provision, estimated start and completion dates, the scope of services and materials, and how change orders are approved and documented in a signed writing.

Roofing is named explicitly in Vermont's definition of residential contracting. Registration applies at an estimated project value of $10,000 or more, inclusive of labor and materials, so most full replacements fall inside it while many isolated repairs do not. Registration is a registry and complaint mechanism, not a state assessment of workmanship — the Office of Professional Regulation states that it does not review contracts for compliance, and a current registration does not guarantee quality, solvency, or availability.

The price provision has to take one of three forms: a maximum price for all work and materials, time-and-materials with a stated not-to-exceed maximum, or time-and-materials with no maximum. Which form a proposal uses changes your exposure to decking and concealed-condition costs more than any other single line in the document.

Down payments are limited when a maximum or not-to-exceed price is used: no more than one-half the cost of labor or one-half the price of materials, whichever is greater. Where the contract is time-and-materials with no maximum price, the down payment is whatever the parties negotiate. A proposal asking for most of the contract value before materials arrive is worth questioning against that standard.

  • Confirm the exact contracting entity name matches the registration and the insurance certificate
  • Confirm which of the three price forms the proposal uses, and what it does when hidden damage appears
  • Confirm estimated start and completion dates are written, not implied by conversation
  • Confirm the change-order process requires a signed writing before extra work proceeds

How the Vermont season shapes roofing schedules

Northwestern Vermont compresses most exterior roofing into the frost-free part of the year, and the practical consequence is that the same job carries different risk in April than it does in late November. Adhesive-dependent details — shingle sealing strips, self-adhering ice-and-water membrane, some low-slope seaming and flashing sealants — depend on temperature and surface conditions to bond as the manufacturer intends. Cold-weather installation is not automatically wrong, but it changes the required methods, and the proposal should say which cold-weather provisions apply.

Demand is also seasonal in a way that affects you as a customer. Storm periods, the first hard freeze-thaw cycle and late-season replacement rushes compress capacity across the whole region at once. Planning a non-urgent replacement outside those windows generally produces more considered proposals and more scheduling flexibility than trying to book during them.

  • Ask what temperature and surface conditions the proposed materials require
  • Ask how the crew protects an opened roof if weather changes mid-project
  • Ask what portion of the work, if any, would be deferred to the following season
  • Ask whether the written start and completion dates account for weather delays

Roofing FAQs

Roof replacement planning for Greater Burlington homes questions

How do I know if I need a full roof replacement?

Replacement becomes more likely when leaks recur, materials are failing across several areas, durable repairs are no longer practical, or broader deck, flashing, or installation problems are present.

Can the exact price be known before tear-off?

A proposal can define the base scope and allowances, but hidden decking or other concealed conditions may not be fully known until roofing is removed.

Can I replace asphalt shingles with standing-seam metal?

Often, but the roofing company should evaluate deck, geometry, ventilation, flashing, snow zones, structural or code considerations, and the complete proposed assembly.

Should the proposal include cleanup and disposal?

Yes. Ask for tear-off, disposal, property protection, magnetic cleanup, permits, final inspection, and excluded work to be stated in writing.

How long does a roof replacement take in Vermont?

A straightforward asphalt replacement on an accessible single-family home is commonly a short project measured in days rather than weeks, but complexity drives it far more than size: steep pitch, multiple dormers, several roof planes, chimney and skylight work, deck replacement, or specialty material can extend it substantially. Ask for written estimated start and completion dates, which Vermont requires in the contract for work valued at $10,000 or more.

Can I put a new roof over the existing shingles?

It is sometimes physically possible and rarely the better decision. Layering hides the deck condition you most need to see, adds weight, can shorten the new roof's life through heat retention, complicates flashing at every transition, and makes the eventual tear-off more expensive. It also limits what a roofing company can warrant. Ask any proposal that includes a layer-over to state why, and what it gives up.

Do I need a permit to replace a roof in Chittenden County?

It depends on the town and the scope. Some municipalities treat like-for-like reroofing differently from structural work, and several Greater Burlington towns publish short-form or over-the-counter paths. Confirm the current requirement with your town's planning and zoning office, and make sure the contract assigns who applies, who pays fees, and who schedules any inspection.

Does the roofing company have to be registered with the state?

For residential work estimated at $10,000 or more, including labor and materials, yes — Vermont requires registration with the Office of Professional Regulation, and roofing is named in the definition of residential contracting. Registration is not a quality rating. It gives you a registry to check standing and a route to file a complaint, and the state does not review contracts for legal compliance on your behalf.

How much of the price can a roofer ask for up front?

Where the contract states a maximum price, or time-and-materials with a not-to-exceed maximum, Vermont limits the down payment to one-half the cost of labor or one-half the price of materials, whichever is greater. Where the contract is time-and-materials with no maximum price, the down payment is negotiated. A request for substantially more than that is worth asking about before signing.

Should I replace the gutters, skylights, and flashing at the same time?

Usually the question is worth asking rather than assuming either way. Anything that has to be removed and reinstalled to complete the roof — flashing, drip edge, sometimes gutters — costs less to replace while the roof is open than as a separate later project, and reusing an aged skylight under a new roof is a common source of a leak on a roof that is otherwise sound. Ask each bidder to price these as clearly itemized options so you can compare like with like.

How is the roof area actually measured for a replacement proposal?

Ground or satellite measurement can approximate square footage, but pitch, valleys, dormers, chimneys, and complexity all change the material and labor needed for the same footprint. Ask whether the measurement was taken from the roof itself or estimated remotely, since the two can produce meaningfully different numbers.

Can any of the existing roof components be reused rather than fully replaced?

Sometimes — sound flashing, an already-compliant vent, or a recently installed skylight might be candidates — but reuse should be a stated, justified decision in the proposal rather than a default. Ask specifically what is being kept and why, since it affects both price and what the new roof can be warranted against.
