What the job involves

Roof Replacement in Hartford, CT

Recover or tear off — what decides it

Recover means a new layer of roofing goes over the old one; tear-off means the old roofing comes off entirely before anything new goes down. Homeowners sometimes treat that as a budget choice, but code treats it as a qualification question, and a roof either qualifies for a recover or it doesn't.

Two conditions rule out a recover outright. A roof that already carries two or more layers of covering can't take a third — code caps how much weight and how many roofing generations a deck is expected to carry. And a roof where the existing covering is water-soaked or has deteriorated past the point of serving as an adequate base has to come off, because a recover only works if the layer underneath is sound enough to build on. Either condition on its own forces a tear-off; nobody gets to choose around them.

The two-layer cap exists for reasons beyond simple weight. Every added layer changes how the next one performs: fasteners driven through two prior layers of shingles have less consistent bite into the deck than fasteners driven through a single layer, and an uneven surface underneath a new layer telegraphs through as ridges and low spots that shed water less predictably than a flat plane would. A recover over a roof that's already carrying its full allowance of layers isn't just against code — it's a worse roof on its own physical terms, independent of the rule against it.

A third, more practical trigger shows up once work starts rather than before: if the deck itself turns out to need replacement, that section has to be exposed and opened up regardless of how many layers are on top of it, which makes a recover impossible for that section by definition. That's part of why the recover-versus-tear-off call sometimes shifts after the crew is already on the roof rather than staying fixed at the estimate stage. Where deck condition is the deciding factor, our roof decking replacement page covers how that gets assessed and priced.

Reading the existing layers

Before either path gets chosen, someone has to establish what's actually up there. That means counting layers, not guessing from the ground — a roof can look like a single course of shingles from the street and turn out to have an older layer underneath once a probe cut is made near an edge or a vent. Layer count is the first fact that has to be settled, since it's one of the two conditions that rules a recover in or out on its own. A step visible at the rake edge, where the roofing material reads noticeably thicker than a single layer would explain, is often the first outward clue that a prior recover already happened before the current layer went down — long before any probe cut confirms it.

Condition matters as much as count. A single layer that's brittle, cupping, or holding water in low spots can fail the same adequate-base test as two intact layers would. Reading that condition means checking for soft spots underfoot, granule loss down to bare mat, and how the material responds to gentle pressure — a sound layer flexes; a deteriorated one crumbles or tears.

Ice barrier membrane gets checked separately from the general roofing layers, because it's handled differently under code. Where an existing ice barrier membrane is already adhered to the deck and still in good condition, code permits that membrane to stay in place and simply be covered with an additional layer of ice barrier rather than being stripped along with everything else. That's a real cost difference between two roofs that otherwise look similar from above — one gets to keep its eave protection in place, the other doesn't.

Attic ventilation gets a look during this same read, even though it isn't part of the recover-or-tear-off decision directly. Soffit intake that's been painted shut or blocked by insulation, or an exhaust vent that's undersized for the roof area it serves, doesn't change which layer-count rule applies, but it does change what gets added to the scope once the recover-or-tear-off decision is made either way.

None of this reading happens instantly. It's closer to an inspection than a glance, and it's the step that turns "replace the roof" from a general instruction into a specific, priced scope of work.

What a tear-off exposes

Once the old roofing is off, the deck is visible for the first time in however many years it's been covered, and that's when problems that were invisible from above get found. Soft plywood, delaminated sheathing, old water staining along a rafter that traces back to a leak nobody caught at the time — a tear-off is often the first honest look the deck has had since the last full replacement.

It's also the point where a roof stops being a repair and becomes a rebuild of the full assembly. With the deck exposed, the job isn't just laying new shingles — it's underlayment, ice barrier at the eaves and valleys, flashing at every transition, and ventilation, all going down in sequence before the new covering ever gets installed. Our roof installation page walks through what that complete assembly includes and why it's more than the visible top layer.

A tear-off also settles arguments a recover leaves open. There's no question about what's underneath once everything's off — no layer hiding a soft spot, no old flashing detail left half-covered by a new one laid on top of it. That clarity is part of what a full tear-off buys, even though it costs more upfront than covering over what's already there.

Through the year

How Hartford weather changes this job

Winter in Hartford

Ice dams build along the eaves when attic heat melts snow that then refreezes at the colder edge, backing water up under the shingles. Sustained snow load also stresses older framing and flat sections built with a lighter deck.

Spring in Hartford

Freeze-thaw cycling through late winter works ice into small cracks in flashing and sealant, so the first heavy spring rain is usually when a slow leak turns visible. Wind during spring storms lifts shingles that ice already loosened.

Summer in Hartford

UV exposure and heat cycling dry out asphalt shingles faster on south- and west-facing slopes. A roof that looked fine in June can show granule loss and curling edges by August.

Autumn in Hartford

The season for getting ahead of winter — gutters cleared, flashing checked, and a full inspection scheduled before the first hard freeze locks in whatever damage went unnoticed over summer.

Common questions about roofing costs and service

Is it worth repairing a slate roof?

Usually, if the slate itself is sound. Slate's service life is long enough that a roof showing isolated cracked or slipped tiles is often a repair problem, not a replacement problem, since the surrounding slate has plenty of life left. Where it stops being worth repairing is when the failures are spread across the roof rather than isolated, or when the flashing underneath the slate has failed and is doing the actual damage regardless of the slate's own condition. That distinction is worth checking before assuming either direction — a full slate replacement is a different scale of project than a repair, and it's not the right call just because a few tiles have slipped.

How much does it cost to have a chimney stack rebuilt?

Chimney rebuilding is masonry work outside what we scope as roofers, so we'd rather point you toward a mason than guess at a number outside our trade. Where our work meets a chimney rebuild is the flashing around it — once a chimney stack is rebuilt, the roof flashing tied into it typically needs to be reset or replaced to match the new masonry, and that's worth having a roofer look at as part of the same project rather than as an afterthought once the masonry work is finished.

How often does a chimney really need to be cleaned?

Cleaning schedules come down to how much the chimney gets used and what's being burned in it, and a chimney sweep is who actually answers that question — it's a flue-interior job, not a roofing one. Where the two trades cross paths is at the top: a sweep's visit is also a natural time to have someone check the crown and the cap for cracking, since a deteriorating crown lets water into the same flue a cleaning is meant to protect. If a roof replacement is already scheduled around the same chimney, coordinating the two visits so the flashing gets reset after any masonry work is worth planning ahead of time rather than sorting out afterward.

How much does it cost to resurface a chimney?

Chimney resurfacing is masonry work, not roofing, so a mason is the better source for that number. What does fall under our scope is what happens at the roofline once resurfacing is done: the flashing where the chimney meets the roof has to be reset against the new surface, and if that step gets skipped, a chimney that looks freshly finished can still leak at the exact same joint it did before the resurfacing work started.
