When a roof has reached the end of its life
Most homeowners start thinking about a new roof after one of three things: a ceiling stain that keeps coming back, a winter of ice dams along the eaves, or a home inspection ahead of a sale or refinance. An in-person inspection by a roofing contractor is how you find out whether the whole roof is worn out or whether the trouble is limited to one area.
- Shingles that are curled, cracked or missing on more than one slope
- Granules collecting in gutters and at the bottom of downspouts
- Daylight through the roof boards, or damp insulation in the attic
- Soft spots, or a visible dip along the ridge or between rafters
- Water stains near exterior walls that return every winter
- An asphalt roof that is roughly 20 years old or more, especially on south- and west-facing slopes
Our guide to the signs a roof needs replacing walks through each of these in more detail.
What happens during a typical replacement
- Inspection. The contractor checks the roof surface, flashing, ventilation and attic, and notes how many layers of roofing are already on the house.
- Written scope and contract. You receive a written description of the work: materials, tear-off, how damaged decking will be handled, ventilation, cleanup and schedule.
- Permit. The contractor typically files for the building permit with your city or town and names the Construction Supervisor responsible for the job.
- Delivery and site protection. Materials arrive, a dumpster is placed, and shrubs, windows and siding are protected.
- Tear-off. The old roofing comes off down to the roof deck, usually one section at a time so the house is not left open overnight.
- Deck check. Rotted or soft boards and sheathing are replaced before anything new goes down.
- Ice barrier and underlayment. A self-adhering ice barrier goes along the eaves and in the valleys, and underlayment covers the rest of the deck.
- Drip edge, flashing and ventilation. New drip edge, step and chimney flashing, pipe boots and ridge or roof vents are installed.
- Roofing material. Shingles, metal panels or a low-slope membrane go on according to the manufacturer's installation instructions.
- Cleanup and final inspection. Debris is hauled away, the yard is swept with a magnet for nails, and the local building inspector signs off where required.

Architectural asphalt shingles are the most common choice on single-family homes across Hampden County. Standing-seam metal sheds snow and suits farmhouses, Capes and additions. Houses with roofs that look flat from the street, including many triple-deckers and porch roofs, need a low-slope membrane such as EPDM, TPO or modified bitumen.
Whatever the surface, the parts you never see do much of the work in this climate: ice barrier at the eaves, good attic ventilation, and tight flashing at chimneys, dormers and walls.
Massachusetts permits, licenses and paperwork
Two different credentials matter for a residential roof in Massachusetts. Contractors who work on existing owner-occupied homes of one to four units must be registered as Home Improvement Contractors (HIC), and roofing on one- and two-family homes generally has to be supervised by someone holding a Construction Supervisor License (CSL), either unrestricted or the specialty license for roof covering. You can look up both numbers on the Commonwealth's online search before you sign anything.
Reroofing typically requires a building permit from the local building department. If you live in one of Springfield's local historic districts, a change in roofing material or appearance may also need approval from the Springfield Historical Commission. Our permits and licenses guide covers the details.
Timing your project
Late spring through fall is the busiest stretch for roofers in the Pioneer Valley. Crews do work through the winter on dry, milder days, but asphalt shingles seal more reliably in warmer weather and short days can stretch a schedule. If your home is in a local historic district, add time for the approval process. See when to schedule a roof replacement for more.
Questions to ask any roofing contractor
- What are your HIC registration and Construction Supervisor License numbers?
- Will you tear off to the deck, and how many layers are on the house now?
- How will damaged decking be handled, and how will it be documented?
- Where will the ice barrier go, and how far up the roof from the eaves?
- How will the attic be ventilated: ridge vent, soffit vents, or both?
- Who pulls the permit and schedules the final inspection?
- What does cleanup include, and how is the yard checked for nails?
- What is the payment schedule?
Questions homeowners ask
How long does a roof replacement take?
On a typical single-family home, tear-off and installation usually take one to three working days once the crew starts, depending on size, pitch, the number of old layers and the weather. Permits, material orders and the contractor's calendar add lead time before that.
Can new shingles go over the old ones?
Sometimes a second layer is allowed, but the building code limits how many layers a roof can carry, and an overlay hides the condition of the deck. Many contractors recommend a full tear-off so damaged boards and the ice barrier can be handled properly. Ask what applies to your house.
Do I need to be home while the roof is replaced?
Usually not, as long as the crew can reach the house, the driveway is clear for the dumpster and pets are kept inside. Many homeowners like to be there at the start of the job and for the final walkthrough.
