Asphalt shingles are the common choice on Connecticut houses, metal suits barns and homes that shed snow, slate and cedar belong mostly to older and historic houses, and flat membranes cover low-slope roofs. No material beats poor attic insulation, so the right choice depends on the roof's shape, its structure and the building's age.
Key takeaways
- Hartford averages about 49 inches of snow and 44 inches of precipitation a year, with January highs near 36 F and lows near 22 F, so a roof here spends months in freeze-thaw cycles.
- Asphalt shingles are the usual residential roof in the suburbs, and the building code limits them to two layers.
- Metal roofs shed snow readily, which is useful on a barn and a decision to plan on a house with a walkway, driveway or neighbor below the eave.
- Slate, cedar and other traditional roofs are most often found on old houses and in historic districts, where local review may apply, so ask before assuming a like-for-like material is allowed.
- Ice dams are mainly a heat and insulation problem. Attic insulation in the R-49 to R-60 range and sealed air leaks matter more than the colour or brand of the roof.
- Published Connecticut cost figures disagree widely, so this guide gives no prices. Get the cost of each option in a written quote.
What does a Connecticut winter ask of a roof?
Snow, ice and repeated freezing and thawing. Hartford records about 49.0 inches of snow and 44.1 inches of precipitation a year, with a January average of 36 F high and 22 F low. A roof here must shed or carry snow, resist ice at the eaves and stay watertight at every joint.
Material is only part of the answer. In this climate the details matter at least as much: the pitch of the roof, the flashing at chimneys and valleys, the drip edge, the underlayment at the eaves, and what is happening in the attic below. Ice dams form when heat escaping into the attic melts roof snow that refreezes at the cold eaves, and the usual conditions are low-20s temperatures lasting several days with several inches of snow on the roof.
That is why a roofer asked about materials will usually ask about the house first. A roof is a system of covering, underlayment, flashing, ventilation and insulation. The covering is the part you can see, and it is also the part most likely to be blamed for a failure that began somewhere else. Our guide to ice dams in Hartford County covers the attic side in more detail.
How do the main roof materials compare in Connecticut?
Asphalt shingles are the most common and the easiest to repair. Metal sheds snow fastest and suits barns and simple roofs. Slate and cedar are traditional on historic houses and need specialist work. Flat membranes serve low-slope roofs. Each performs only as well as its flashing, underlayment and the attic beneath it.
The table compares the common options in plain terms. It deliberately avoids prices and lifespans: the cost figures that circulate for Connecticut come from contractor marketing pages and disagree widely, and a lifespan depends on installation, ventilation and exposure as much as on the product. A roofer can describe what each option would involve on your house.
| Material | Where you tend to see it here | How it handles snow and ice | What to ask |
|---|---|---|---|
| Asphalt shingle | Suburban houses across Hartford County, from mid-century ranches to newer homes | Holds snow until it melts; vulnerable to ice dams if the attic leaks heat | How many layers are on now? Will it be a tear-off? |
| Metal (standing seam or panel) | Barns, farm sheds and some houses, such as around South Windsor and Burlington | Snow slides off quickly, sometimes all at once | Where will the snow land, and will snow guards be fitted? |
| Slate | Older and historic houses, especially in village and campus areas | Sheds snow well; heavy; individual slates crack or slip with age | Can the structure carry it, and who does slate repair? |
| Cedar shakes or shingles | Older houses and some historic districts | Needs air movement; moss and moisture are common on shaded slopes | Will a historic district allow a substitute? |
| Flat or low-slope membrane | Multifamily buildings, additions, and large apartment or commercial roofs, such as in Bloomfield and New Britain | Holds snow until melt; drains and seams matter most | Which membrane, and how will edges and drains be flashed? |
Are asphalt shingles the right default for a Connecticut house?
For most single-family houses in the suburbs, yes. Asphalt shingle is the usual residential roof, is widely understood by roofers, and can be repaired in sections. The building code limits asphalt shingles to two layers, so a roof that has already been covered twice must be torn off to the deck before the next one goes on.
Much of the suburban housing around Hartford, including the mid-century streets of Newington, mostly wears asphalt shingles. They are familiar, a roofer can match or patch them, and most roofing contractors work with them every week. Architectural, or laminated, shingles are thicker than the older flat three-tab type, which is why you will hear them recommended for roofs that face wind and snow.
The tradeoff is that a shingle roof depends on everything underneath. Shingles over a poorly insulated attic can still produce ice dams, and nailing, flashing and underlayment at the eaves matter at least as much as the shingle itself. When you compare quotes, ask what goes under the shingles at the eaves and in the valleys, not just the name on the bundle.

When does a metal roof make sense?
Metal makes sense on a barn or farm building, on a simple roof where snow can slide off without hitting anyone, and where you want a roof that sheds snow quickly. It needs careful flashing and planning for the sliding snow, and it is a specialist job, so ask for a roofer who installs it regularly.
South Windsor has long been agricultural, with tobacco sheds still dotting the town, and Burlington is a rural hill town of large wooded lots. Barns, sheds and farm outbuildings are the classic uses of metal roofing in towns like these, and some homeowners choose it for the house too because snow leaves it readily.
That same quality needs planning. Snow that slides off all at once can land on a walkway, a porch, a driveway, a parked car or a neighbor's property, so roofers often fit snow guards or design the roof around where the snow will go. Metal also changes how rain sounds inside, and it needs flashing at chimneys, skylights and valleys that suits the panel type. Our page on metal roofing goes through the choices.
Because no local price for metal is sourced, this guide does not quote one. Ask each roofer for a written scope that names the panel type, the underlayment, the snow-guard plan and the flashing. If two quotes differ, the difference is usually in those lines, not in the headline.
What about slate, cedar and other traditional roofs?
Slate and cedar are most often found on older and historic houses. They need specialist installers, may be subject to local historic review, and are not always replaced by like-for-like materials. If your house has one, do not assume it must go; a roofer experienced in traditional roofing can say whether repair is possible.
Connecticut has a deep stock of old houses, including Old Wethersfield, the state's largest historic district with about 1,100 buildings, more than 150 of them built before 1850. The Cheney district in Manchester holds about 210 company houses from 1850 to 1920, and Glastonbury and West Hartford have historic districts of their own. Roofs on very old houses in a historic district can involve special materials or local review, so ask whether district rules apply before work starts.
Older village houses in towns such as Farmington may also have slate, cedar or several shingle layers, so ask for a tear-off inspection before agreeing a scope. A like-for-like replacement can be a skilled and slow job, and a substitute material may or may not be allowed where you live. Our page on roofing for historic homes covers what to ask.
Which roof suits a flat or low-slope building?
A flat or low-slope roof needs a continuous membrane rather than shingles. Common choices are built-up roofing, modified bitumen, EPDM rubber and TPO, chosen according to the building and how the water will drain. What counts most is the detailing at drains, seams, edges and penetrations.
Triple-deckers and multifamily buildings in Hartford and New Britain often include flat or low-slope sections, and newer apartment and warehouse construction in Bloomfield includes large flat-roofed buildings. On a roof like this, water does not run off by gravity alone. It has to be steered to drains, and every seam and edge is a place where the membrane could let go.
Because one house can combine a pitched main roof with a flat porch or addition, you may need two systems on one building. A roofer who explains both and shows how they meet is giving you a good sign. Our guide on roofing a triple-decker or multifamily building goes further into flat roofs.
How should you choose between materials?
Start with the building: its age, shape, structure, the number of layers on it now and whether it sits in a historic district. Then compare written quotes that name the material, underlayment, flashing and ventilation. The cheapest line is rarely the one that tells you most about the job.
Published Connecticut guides give very different figures, some with a premium for Connecticut construction costs and some without, and they come from companies selling roofs. That is why this site shows no price table. The reliable number is the one in your own written quote, from a roofer who has looked at your house.
A full re-roof needs a building permit under the 2022 Connecticut State Building Code, and the town sets its own rules, so ask who applies for it. Structural changes, such as a changed pitch, need extra plans. Before you compare anything, gather the facts a roofer will ask for: the house's approximate age, the roof's shape, whether you have seen leaks, whether any ceiling has stained, whether trees overhang it, and whether the house sits in a historic district. Photographs from the ground help a roofer prepare, though they cannot replace a visit. When you call Hartford Roofing, say what you have on the roof now and what you are thinking about. The independent roofer you reach can then talk through options with that in mind.
Frequently asked questions
Is a metal roof better for Connecticut snow?
Metal sheds snow faster than shingles, which suits barns and simple roofs. It is not automatically better for a house. Falling snow needs somewhere safe to land, and a poorly insulated attic can still lose heat and form ice at the eaves under any roofing material.
Can I put new shingles over old ones?
Only within the limit. Asphalt shingles are restricted to two layers under IRC R908.3, so a roof that already has two layers needs a tear-off. Even with one layer, a roofer may recommend stripping it to inspect the deck. Ask the roofer to explain the choice in writing.
Do historic districts restrict roof materials?
They can. Roofs on very old houses in a historic district may involve special materials or local review. Ask the town building office or historical commission whether district rules apply to your address before you choose a material or sign a contract.
Does roof colour matter for ice dams?
Not much. Ice dams come from heat escaping into the attic and melting snow that refreezes at the eaves. Insulation, air sealing and ventilation address the cause. Colour can affect how quickly snow melts in sun, but it does not fix a leaky attic.
Which material should I choose for a barn or shed?
Metal is a common choice for barns and sheds, which is why it comes up in agricultural towns such as South Windsor and Burlington. Ask the roofer about panel type, fasteners, flashing and where sliding snow will land, and get the scope in writing.
