Replacement

Roof Replacement: what it covers

Quick answer

A roof replacement strips the old covering down to the deck, checks and repairs the boards, lays new underlayment and flashing, and installs a new covering. In Stamford the job is shaped by the coast: nor'easters, ice dams at the eaves and a housing stock that runs from multifamily blocks to slate estates.

Roof Replacement illustration for Stamford, CT

Most roofs in Stamford do not belong to the person who lives under them. The city's owner-occupancy rate is 48.8 percent, against 66.5 percent for Connecticut as a whole, so a replacement is often decided by a landlord, a condominium board or a managing agent rather than by a homeowner alone.

A replacement is a different job from a repair. The covering comes off, the deck is exposed, and the technician decides what can stay and what has to go. Where an old roof has been patched for years, the decking is usually the real question, and it can only be answered once the old material is off.

The rest of this page covers what the work involves on this shore, what moves the job up or down, and what a homeowner can check from the ground before a crew arrives.

How long does a replacement take, and what can change the timing?

The timing follows the roof itself: its area, its pitch and how many planes it has, how easily crews can reach the eaves, and what the deck looks like once the old covering is off.

A roof that has been patched for years may have wet boards along a valley or beneath a chimney, and each of those has to be opened, dried and replaced before the new covering can be fixed.

What moves the price up or down on a Stamford roof?

Size and pitch, the number of planes, height and access, the layers already on, the condition of the deck, the flashing and the gutters, and which state the house is in. The price is explained item by item and approved before any work starts. This page names no figure, and this site publishes no price for roofing work.

Size and pitch set the material and the labor before anything else. A steep roof is slower to work and needs more fall protection, and a roof with many planes, dormers and valleys has more cuts, more flashing and more places where a leak can begin. Greenwich and New Canaan houses often carry all of these at once, which is why their quotes look different from a simple gable.

Condition is the one thing nobody knows until the old covering is off. The number of layers, the decking under them and the state of the flashing all change the scope. The technician records what is found and explains the change before doing it, so the homeowner sees why a line moved and can decide with the facts in front of them.

Does a full replacement need a building permit in Stamford?

Often, yes. Stamford's Building Department runs a roofing track of its own, with a roofing application and a roofing affidavit form. The city's own guidance says ordinary repairs to structures do not need a permit, which is exactly why the line between a repair and a replacement matters.

The city publishes a list of work that is exempt from permit requirements, and its FAQ says an ordinary repair does not need one. A full tear-off and new covering is a different thing, and a roof and siding permit can be issued for it. When that permit is issued without a building permit, a final inspection has to be called in before a Certificate of Approval can be issued, and the crew plans the finish around that inspection.

What does the Connecticut contractor rule require from a roofer?

Connecticut issues no roofing license. A roofer doing residential work registers as a Home Improvement Contractor with the state Department of Consumer Protection, and every home improvement project needs a written contract the homeowner keeps a copy of.

The registration applies to residential property of six units or less, where the contractor charges more than $1,000 in any twelve consecutive months. There is no exam, because it is a registration rather than a trade license. The state checks registrations at elicense.ct.gov, and the registration number on a contract should be looked up there before any deposit changes hands.

What changes if the house is across the state line in Westchester County?

The rules change completely. New York State does not license home improvement contractors, but Westchester County does, and its licensing law names roof work explicitly. A Connecticut registration does not authorise work in Port Chester, and a Westchester license does not authorise work in Stamford.

The county license covers residential property of up to three units, and working without it is a misdemeanour under county law. Licensed contractors must display a green sticker on the rear bumper showing the license expiry date.

Warning signs

Signs you need roof replacement

Do not walk a steep, wet or frosted roof, and do not strip the old covering yourself. Slate and tile cracked during removal cannot be reused, and a roof with soft decking can give way under a person long before it shows any sign from below. Do not sign a contract that lacks the registration number or the four dates the state requires.

  • Granules from the covering collecting in the gutters and at the downspout outlets
  • Shingles that curl at the edges or lie flat where they used to lift
  • Dark, soft or spongy boards visible from the attic along the rafters
  • Daylight or staining around a chimney, a skylight or a dormer wall
  • Ceiling stains that appear in a wet spell and dry out, then return
  • Nails backing out of the sheathing, with heads standing proud of the surface
  • Sagging along a ridge or a slope that used to run straight
Our process

How our roof replacement visit works

  1. Inspection and measurement

    A technician walks the roof where it is safe to do so, measures each plane, notes the pitch and counts the layers already on. Every valley, dormer, chimney and wall junction is recorded, because those are where a new covering most often differs from the old one in both cost and detail.

  2. Tear-off to the deck

    The old covering comes off down to the sheathing, and the material is carried away in a way that keeps the site clear of debris and keeps occupied areas below dry.

  3. Deck repair

    Once the covering is off, the boards are checked by eye and by touch. Soft or delaminated sheathing is marked and replaced before anything is laid over it, because a new covering cannot hold to a deck that will not take a nail.

  4. Eave protection and underlayment

    Along the eaves and in the valleys, a self-adhering ice barrier is laid under the covering. This is the layer that resists water pushed back up under the shingles when an ice dam forms. Connecticut's building code sets where and how far it must run, and the building inspector confirms that for the address.

  5. Flashing, covering and final walk

    Old flashing is replaced rather than bent back into place, because a flashing that has been worked once rarely seals again. The new covering goes on to the manufacturer's instructions, the ridge and hip details are closed, and the lawn and driveway are swept for nails. The technician walks the finished roof with the homeowner and covers any inspection the permit requires before the job is called done.

Options

Types and options for roof replacement

Asphalt shingle replacement

This is the common covering on the post-war and mid-century houses across the inland rows, and on many smaller multifamily buildings. The usual method is a full tear-off to the deck, with the eave detail and the ventilation at the ridge treated as part of the same job.

Slate or clay tile replacement

Slate turns up on the older and larger houses in Greenwich and the wider Gold Coast, and clay and concrete tile on the Mediterranean-revival estates. On these roofs the existing covering is often the asset, so a repair frequently beats a replacement. When a replacement is needed, the fixings deserve the most care, because on historic slate and tile the nails usually fail before the stone does.

Flat or low-slope replacement

Downtown and South End buildings, rear ells and the modernist houses of New Canaan are often flat or nearly so. The covering is a membrane rather than shingles, the water is carried to drains and outlets, and the detail where the roof meets a wall or a run of glass decides how it performs.

Fairfield County

Why roof replacement is different in Coastal Fairfield County and lower Westchester

The storm that tests a Stamford roof hardest is often not the one that carries a name. A nor'easter is most frequent and most violent between September and April, and its gale-force winds push rain and wet snow across this shore. East winds along the axis of Long Island Sound also drive surge into the western end of the Sound, which is why Stamford, Greenwich and Norwalk take water in ways inland towns do not. During Sandy, about 3,000 Connecticut homes were damaged, and the highest measured inundation in Fairfield County was 4.5 feet, at Norwalk.

Snow is the other half of the picture, and this shore gets less of it than inland New England. The nearest National Weather Service climate station, the Bridgeport airport about 30 kilometres east of Stamford, has a 1991 to 2020 normal of 33.6 inches of annual snowfall. That is not a measurement of Stamford itself, but it is the honest reference for the coast. The inland rows, from Wilton and Weston to Pound Ridge, Armonk and Bedford, hold snow longer under heavier tree cover, so the eave detail on those roofs has to hold for a longer season.

The housing mix shapes the job. Downtown and the South End carry dense multifamily blocks, where the roof is a shared asset with an owner, a board or a managing agent. Greenwich and Old Greenwich hold large houses with several roof planes and slate or tile on older estates. New Canaan has modernist houses with flat roofs over glazed rooms. Stamford's owner-occupancy rate of 48.8 percent, against 66.5 for Connecticut, means the person who signs is often not the person who lives underneath, so that is the first question to settle.

FAQ

Roof Replacement FAQs

Is a roof replacement the same as a roof repair?

No. A repair fixes a defined area, such as a valley, a patch of shingles or one flashing, and leaves the rest of the covering in place. A replacement removes the covering down to the deck, checks what is underneath and installs a new system. The difference matters for the permit, and it is also what lets a crew see the decking, which a repair never does.

Can a new covering go over the old one?

Sometimes, but the answer comes from the roof, not from a rule of thumb. A 2024 Codes and Standards Committee amendment to the roof-replacement section lets an existing adhered ice barrier stay in place under a new layer where the manufacturers permit it, so the building inspector and the manufacturer's instructions are the authority.

Will I know the price before the work starts?

Yes. The price is confirmed on site, explained item by item and approved before any work starts. The factors that move it are the ones on this page. No figure is published on this site, because a number printed without a site visit would be a guess.

What about slate or tile on my house?

Slate and clay tile are often the most durable part of an older roof, but the fixings usually fail first. Slate is fixed with non-ferrous nails, solid copper or stainless steel, because plain steel nails rust out well before the slate does, and nails driven too deep crack it. Tile is often fastened with nails that corrode. A replacement on either material starts with the fastening, not the stone.

How do I check that a roofer is registered in Connecticut?

Ask for the Home Improvement Contractor registration number and look it up on elicense.ct.gov, the state system the Department of Consumer Protection uses. The number should appear on the written contract. A roofer who cannot give one should not be paid a deposit, and a registration can be checked before any work is scheduled.

Do I need to be home while the work is done?

It helps to be reachable, and the managing party or board usually signs. Where the house is occupied, the crew keeps the work area clear and checks that rooms below stay dry.
