What the job involves
Roof Skylight Installation in Hartford, CT
Curb-mounted versus deck-mounted
A curb-mounted skylight sits on a raised wood frame built up from the deck, with the glazing unit set on top of that curb and flashed around its base. That separation between curb and unit is what makes this style repair-friendly over the long run — the glazing can be replaced later without disturbing the flashing, and the flashing can be reset without pulling the whole unit, because the two are distinct components rather than one integrated piece.
A deck-mounted skylight skips the curb entirely and sits lower, closer to the roof surface, with its own frame doing the flashing job directly against the deck. That gives a sleeker profile and a lower-visibility installation, but it also means the frame and the flashing are effectively one system. A flashing failure on a deck-mounted unit tends to mean addressing the frame's integrated flashing kit as a whole, rather than isolating the problem to a separable curb, a separate flashing layer, and a separate seal the way a curb-mounted skylight allows.
That difference is really a decision about how future problems get handled, made at the moment of installation rather than later. Skylight and roof-penetration leaks are commonly traced back to failed sealant or deteriorated flashing around the curb rather than the glazing unit itself, which is exactly the failure mode a curb-mounted design isolates into separate, individually repairable parts. Choosing the mount type is choosing how a leak, years from now, will get diagnosed and fixed.
Sizing and placement
A bigger skylight means a bigger hole cut into the roof framing, which usually means cutting one or more rafters and adding structural support around the opening to carry the load they used to carry on their own. That framing work has to happen correctly before flashing even enters the picture, since a poorly supported opening can flex slightly over time in a way that stresses the flashing seal around it regardless of how well that flashing was installed.
Placement matters as much as size. A skylight set well within a clear roof plane, away from valleys, ridges, and other penetrations, gives the flashing kit a straightforward, uninterrupted area to work in. A skylight placed close to a valley or another vent or pipe forces two separate flashing systems to negotiate the same small stretch of roof, and that crowding is exactly where installation mistakes are more likely to happen — there's less room for a clean lap sequence when another roof detail is competing for the same few feet of surface.
Neither of these decisions can be corrected easily after the fact. Reframing an opening or relocating a skylight once it's installed means undoing finished work, so getting the size and the placement right at the start avoids a much larger job down the road just to fix a decision that could have gone differently from day one.
Orientation and slope play into this too, though less dramatically than size or proximity to another roof detail. A skylight set on a steep slope sheds water off its own surface faster than one on a low-slope section, which changes how much standing water the flashing around it ever has to deal with in the first place. None of these factors override the basic rule that a clean, uncrowded stretch of roof plane is easier to flash correctly than a tight one, but they're worth weighing together rather than deciding on size or placement in isolation from the other.
Flashing kits and why they matter
Skylight manufacturers build flashing kits matched to a specific unit and, often, to a specific roofing material — a kit designed for an asphalt shingle roof isn't built the same way as one meant for a metal or tile surface, because each material sheds water differently at the transition. Using the kit that actually matches both the skylight and the roofing it's going into is what makes the lap sequence around the unit work the way it's supposed to.
Improvising a flashing solution instead of installing the matched kit — cutting and bending generic flashing stock, or leaning on extra sealant to close gaps a proper kit wouldn't have — is one of the more common ways a brand-new skylight ends up with an early leak. The unit itself can be flawless and still leak within a season or two if the flashing around it wasn't built for that specific combination of skylight and roof surface.
The same logic applies to how the flashing kit integrates with whatever ice barrier membrane already runs under the shingles at that point on the roof. A kit installed without accounting for that membrane can leave a gap in the lap sequence right where the two systems are supposed to hand off to each other, even if each one looks correctly installed when checked on its own. That handoff is exactly the kind of detail that's invisible once the shingles go back down, which is another reason the flashing kit deserves as much attention during installation as the skylight unit itself.
Getting the flashing right at installation is the highest-leverage decision in the whole job, precisely because most future skylight leaks trace back to that detail rather than to the glazing. For a skylight that's already showing signs of a leak rather than one being installed fresh, our roof skylight repair page covers how we work through curb, flashing, and seal to find which one actually failed.

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.

Straight answers
Common questions about roofing costs and service
Are ice dams bad for your roof?
Yes, in more than one way. The ice itself adds weight along the eave that the roof structure isn't necessarily built to carry for weeks at a time, and the standing water it creates behind the dam gets forced up under the shingles rather than running off the way the roof is designed to shed water. Beyond the immediate risk of an active leak, repeated ice damming season after season tends to accelerate wear on shingles and flashing right at the eave, since that stretch of roof is taking on standing water and freeze-thaw stress the rest of the roof surface never sees.
Do I need a permit for DIY gutters?
That depends on your local building department, and it's worth a quick call to them rather than assuming either way, since permit rules vary by town. What's usually different about a skylight, by comparison, is that cutting into the roof deck and framing to install one is structural work in a way that hanging a gutter typically isn't, so a skylight project is more likely to fall under permit and inspection requirements regardless of what a gutter project needs.
Can you repair a slate roof?
Yes, slate can generally be repaired, though it takes a different skill set and material sourcing than asphalt shingle work. Matching replacement slate to the existing color, thickness, and size is part of doing it correctly, and the roof has to be walked carefully during the repair, since slate is more brittle underfoot than asphalt and cracks easily if stepped on wrong. A skylight set into a slate roof carries that same consideration — the flashing work around it has to account for slate's thickness and fragility rather than being treated the same as a shingle installation.
Is R60 attic insulation worth it?
Whether a specific insulation level is worth it depends on your climate zone's current recommended range and what you already have up there, which is a question for an insulation contractor rather than us. What we can say from the roofing side is that adequate attic insulation, whatever the right level turns out to be for your house, is part of what keeps heat from reaching the roof deck and driving problems like ice damming at the eave — a factor worth weighing alongside the pure cost-of-heating math an insulation contractor will walk you through.
