Design criteria for an Andover roof
The state assigns Andover an ultimate design wind speed of 120 mph — 93 mph nominal — in Appendix AY of the 2022 Connecticut building code. Statewide, 147 municipalities carry an equal or higher rating. Connecticut's amended R905.1.1 applies statewide, so the sealed roof deck requirement is triggered on a full tear-off here.
Ground snow load in Andover is 30 psf. Baseline loading for the state, which puts the emphasis on eave detailing rather than on structure.
Connecticut amendments that apply here
Two Connecticut amendments matter on almost every job. The first is statewide ice barrier, R905.1.2: from the lowest edge of the roof to a point 24 inches or more inside the exterior wall line, measured on the slope. On a shallow pitch that is a surprising amount of membrane. The second is R905.1.1, the sealed roof deck rule, which has an exception for lumber sheathing of less than 3 feet nominal width — common on older housing stock here.
It matters here because 55.5% of Andover homes predate 1980 - the median was built around 1975 - so plank decking and older fastening turn up regularly on tear-offs in this town.
Four is code, six is warranty. Connecticut's minimum is four nails per shingle; the shingle manufacturers want six before they will stand behind a wind claim. We use six. What we will not do is tell you the state requires it, because it does not.
The climate a roof in Andover has to take
The nearest weather station with a thirty-year record sits about 9 miles from the center of town at Storrs. Its readings - NOAA's 1991-2020 normals - say what a roof in Andover actually has to put up with.
Snow: 39 inches in an average year, which is about average for Connecticut. It falls across roughly 11 days that leave an inch or more, and 5 that leave three inches or more. The weight is not usually the problem. The problem is melt that refreezes at the cold edge of the roof and forces water back up under the courses, which is exactly what the ice barrier at the eaves is for.
Freeze-thaw: about 123 nights a year drop below freezing, and 36 days never climb above it. Each of those nights works on whatever is already loose - a lifted tab, a tired boot around a pipe, a nail that has backed out. Winter finds the weak spot and makes it bigger.
Rain: 49 inches a year, including about 13 days when an inch or more falls in a single day and 2 that top two inches. That is a lot of water to move off a roof, and it finds the same three places every time: valleys, gutters that cannot keep up, and wall junctions with no kick-out flashing.

What the storm record says about Andover
There is a public record of severe weather, town by town. For the ten miles around Andover, this is what NOAA confirmed across 2015-2026.
63 damaging-wind reports, the strongest put at 81 mph. Wind works the edges first - the rake, the ridge, the starter course at the eave - and an old roof loses its seal strips long before it loses shingles.
13 hail reports, the largest 1.5 inches across - about the size of a ping-pong ball. That is past the bruising range. Hail of that size splits the mat under the granules, and a split mat lets water into the shingle itself.
Also on the record: 3 confirmed tornadoes touched down inside the same circle and the National Weather Service logged 31 winter-storm, heavy-snow or ice-storm events for Tolland County over the same years.
After a storm like those, the sensible move is a look at the roof before anything leaks - we do that for free in Andover, and you get the photographs either way. If there is damage, our storm damage report puts the photos, measurements and a written estimate in one place for your insurer.

Permits and inspections in Andover
Andover issues roofing permits through its building department. The building official on record is Rich McKinnon. Staffing is part-time, so inspection slots are limited. We book around them rather than hoping. The published number is 860-649-8066 x6103. Written questions go to rmckinnon@boltonct.gov. We pull the permit as part of the job. No homeowner should be asked to pull their own roofing permit by a contractor working on their house.
A roof replacement permit in Connecticut is generally issued over the counter or online once the scope is submitted, with an inspection at completion. Where a house sits in a local historic district, or where zoning or health review applies, that approval comes first and can add real time. If your property is affected, we will tell you before the contract is signed rather than after the dumpster arrives.
What Andover's housing stock means for a new roof
Andover's housing is newer than Connecticut's as a whole. Census estimates place 23.4 percent of the town's 1,289 housing units in buildings from 2000 or later, nearly twice the statewide 11.8 percent and more than double the 10.8 percent across the Capitol Planning Region. The median year built is 1975, against 1967 for the state, so the typical Andover house is about 51 years old in 2026. The stock is almost all detached single-family houses (95.8 percent), and owners live in 93.9 percent of occupied homes.
That split gives the town two separate roof conversations. For the newer houses the question is timing. InterNACHI's life-expectancy chart puts 3-tab asphalt shingles at about 20 years and architectural shingles at 30, with the caveat that weather, design, material quality and upkeep all move those figures. Many post-2000 houses here are likely still wearing their first roof, and the oldest of them have already entered that 20-to-30-year window. For the house that sits at the median, the first roof has likely been replaced at least once, and the covering up there now may itself be nearing its end.
At either age the code treats a full job the same way. IRC R908.3, adopted in Connecticut without amendment, defines roof replacement as removing the existing layers of covering down to the deck. In practice a new Andover roof starts with a tear-off and a look at the bare deck, not a fresh layer over tired shingles. Smaller damage is handled differently: Connecticut's amended R105.2 exempts from permits repairs limited to 25 percent of the roof covering within one calendar year. A few lifted courses on one slope can fall under that line; a replacement never does.
The older part of the stock should not be forgotten. Houses built before 1940 make up 19.2 percent of the stock, close to the state's 20.4 percent, and 55.5 percent of all units predate 1980. Those numbers carry a caution, though. With a housing count this small, the survey reaches few households and each share has a wide margin, so read the table below for direction rather than decimals: newer and more owner-occupied than Connecticut overall, with a real minority of old houses mixed in.
| Housing (ACS 2019–2023) | Andover | Connecticut |
|---|---|---|
| Housing units | 1,289 | 1,536,049 |
| Owner-occupied homes | 1,102 | 939,912 |
| Share owner-occupied | 93.9% | 66.2% |
| Single-family detached | 95.8% | 58.7% |
| Median year built | 1975 | 1967 |
| Built before 1940 | 19.2% | 20.4% |
| Built 1940–1979 | 36.4% | 47.4% |
| Built 1980–1999 | 21.1% | 20.5% |
| Built 2000 or later | 23.4% | 11.8% |

How Andover compares with the towns around it
Every town Andover borders is rated for equal or stronger wind. Crossing the town line here means a heavier fastening schedule, not a lighter one.
| Bordering town | Design wind | vs. Andover | Ground snow | County |
|---|---|---|---|---|
| Bolton | 120 mph | same | 30 psf | Tolland |
| Columbia | 125 mph | +5 | 30 psf | Tolland |
| Coventry | 120 mph | same | 30 psf | Tolland |
| Hebron | 125 mph | +5 | 30 psf | Tolland |

Common questions about roofing in Andover
Is ice barrier required on an Andover roof?
Yes — Connecticut requires it statewide under code section R905.1.2, running from the lowest roof edge to at least 24 inches inside the exterior wall line. With a 30 psf ground snow load in Andover, that detail is doing real work.
How many nails per shingle should be used in Andover?
Connecticut's code minimum is four. Shingle manufacturers require six to keep their wind warranty in force, and six is what we install. Six nails is a manufacturer requirement, not a code requirement.
Have you worked in Andover before?
Yes. Our records show 2 completed roofs in Andover. That count comes from our own job history.
Do I need a permit to replace a roof in Andover?
Yes. A roof replacement in Andover requires a building permit, and we pull it as part of the job. The building department's published number is 860-649-8066 x6103 if you want to confirm anything independently.
Who is the building official in Andover?
Rich McKinnon is the building official on record for Andover, per the State of Connecticut list of municipal building officials. Staffing changes — confirm with the town before relying on it.
What wind speed does a roof in Andover have to be designed for?
The 2022 Connecticut State Building Code assigns Andover an ultimate design wind speed of 120 mph. That figure sets the fastener schedule and the manufacturer wind rating we specify.
Does Andover get hail?
Yes, and it is worth taking seriously. NOAA has 13 confirmed hail reports within ten miles of Andover since 2015, the largest 1.5 inches across. Stones that size crack the mat under the granules rather than just bruising it, so the damage is real even when the roof looks sound from the driveway.
Are ice dams a problem in Andover?
They are the winter problem worth planning for. The nearest long-record station averages 39 inches of snow a year across about 11 days that leave an inch or more, and roughly 123 nights below freezing. That is the exact recipe for melt at the warm middle of a roof refreezing at the cold eave. Connecticut's code answer is an ice barrier at the eaves; the practical answer is that plus attic insulation and ventilation that keep the roof deck cold.
