If you’ve decided your Medford roof is probably done and you’re choosing who does the work, this page is for you: what a replacement involves on the three kinds of house Medford is built from, the cost ranges they land in, and the two local details — eave protection and attic ventilation — that decide how the new roof behaves in January.
Then don’t start here. Read repair or replace — how to tell first, or call Thiago on (617) 721-1814. We do repairs too, so we’re not looking for a reason to sell the bigger job. For repair, siding and the slate question, see the Medford roofing page.
What a Medford replacement involves, by house type
The layer-by-layer specification lives on our roof replacement page and doesn’t change by neighborhood. What changes is how hard it is to install on your house — and that’s most of your price.
Hillside and the Tufts-area two- and three-families
Tall, close together, often no usable driveway, frequently tenanted. The roofing is straightforward; the setup isn’t. On a three-story house we stage rather than work off ladders, and dumpster placement, street occupancy and the tenant schedule are settled before a start date exists.
The detail that catches owners out: most of these buildings have a low-slope section over the rear ell or porch stack, and asphalt shingles don’t work on a slope that shallow. That area needs a membrane, priced as its own line. A quote that prices the building as “shingles” isn’t finished.
West Medford and Lawrence Estates colonials and Victorians
Bigger, older, steeper. Third-floor attics, multiple dormers, valleys running several directions. The open field of shingle is the cheap part — the money is in valley metal, step and counterflashing at dormers and chimneys, and the staging a pitch nobody can walk demands. That’s where a low bid finds its savings, because none of it shows from the sidewalk.
Wellington, Glenwood and the post-war capes and ranches
Walkable pitch, one or two planes, room in the driveway for a dumpster. The least expensive roofs to replace in the city, usually done in a day. The real question isn’t the shingle — it’s ventilation and decking. These are on their second or third roof, and the soffit intake is often blocked or was never adequate.
What it realistically costs in Medford
Nobody can price your roof from a street view and we won’t try. But you deserve a real bracket before you take three appointments. Most single-family replacements in Massachusetts land around $12,000 to $18,000, full spread roughly $9,000 to $25,000. Architectural shingles installed run about $450 to $750 per square — a square being 100 square feet of roof surface, not floor area.
| Medford house type | Where it usually sits | Why |
|---|---|---|
| Wellington / Glenwood cape or ranch | Lower end | Walkable pitch, simple planes, driveway access, minimal flashing. Ventilation correction is the common add. |
| Ordinary two-story colonial | Middle of the bracket | A chimney, a couple of valleys, ordinary access, average surface area. |
| West Medford / Lawrence Estates colonial or Victorian | Upper end | Steep pitch and height, staging, dormers, several valleys, extensive flashing, larger surface. |
| Hillside two- or three-family | Upper end, priced in two parts | Staging, no driveway, street logistics, tenants — plus a separate low-slope membrane section. |
The Massachusetts cost guide breaks each driver down, and asphalt shingle replacement covers the material side. Whatever you’re quoted, the number should arrive with a written scope attached.
State code requires an ice barrier — ice & water shield — at the eave edges of a new roof. It typically adds around $300 to $600 and isn’t optional here. If one Medford quote comes in much cheaper than the others, this is the first place to look. Ask how far up from the eave the membrane runs, and whether the valleys get it too.
Trees, valleys and drainage
Medford’s mature canopy is a detailing decision on a replacement, not a landscaping one. Leaf litter packs into valleys and eave troughs, water backs up behind it, and in a February freeze it becomes an ice plug sitting exactly where the roof is weakest. So on canopy streets we run the ice barrier up the valleys as well as the eaves, and check the gutters can keep up. A new roof that drains like the old one ages like the old one.
Ventilation — what decides how the new roof winters
Most Medford housing stock predates any real thinking about attic airflow. A roof needs balanced ventilation: intake low at the soffits, exhaust high at the ridge. When insulation blocks the intake — very common on the post-war capes — a ridge vent alone does close to nothing. Warm air sits under the deck, melts the snow above, the meltwater refreezes at the cold eave, and you have an ice dam on a brand-new roof. We check this in the attic at the estimate, and any correction is its own line.
What’s on the written estimate
Short version — the full specification is on the replacement page:
- Full tear-off to bare deck, existing layers stated
- Decking allowance and the per-sheet price if we find more
- Ice & water shield at eaves, valleys and every penetration
- Drip edge, step and counterflashing, valley metal, pipe boots — all new
- Ridge vent and intake ventilation, correction priced separately
- Any low-slope section as its own membrane line
- Staging, dumpster and cleanup — included, not “additional”
Scheduling and access in Medford
A cape or ranch is usually a single day. A typical colonial, one to two. A three-story two-family with staging and a rear membrane section runs two to three, plus setup. We don’t open more roof than we can make watertight before we leave, so a bad forecast moves your start date rather than stretching the job over an open deck.
Access is the Medford-specific piece — narrow streets, tight side yards, tenant parking, limited driveway space — all worked out before the start date. Late spring through fall is the easiest window, though we work year-round. Here’s what install day looks like, and the rest of our service area works the same way.
We get on the roof, look in the attic, and hand you the full written specification with a price. If the roof has years left, we’ll say so. Book a free estimate or call (617) 721-1814.
Medford roof replacement questions
What should a roof replacement cost on a typical Medford colonial?
An ordinary two-story colonial with a chimney and a couple of valleys usually sits mid-bracket — roughly $12,000 to $18,000 — driven by surface area, pitch, layers coming off and flashing work. A steep West Medford Victorian with several dormers pushes past that; a Wellington ranch sits below it. Anyone quoting it over the phone is guessing.
I own a tenanted two-family near Tufts. Do tenants have to move out?
No. You get a schedule to pass on beforehand — start date, the noisy window, where the dumpster and staging sit, and which days parking is affected. Tear-off is loud inside, so most landlords warn anyone working from home.
Why does my quote include ice & water shield when a cheaper quote doesn’t?
Because Massachusetts code requires an ice barrier at the eave edges, and on a Medford roof it’s the layer that keeps ice dam meltwater out of your ceiling. It typically adds around $300 to $600. A quote without it — or with a token strip at the eave and nothing in the valleys — is cheaper for a reason.
My rear porch roof is nearly flat. Can it just get shingles like the rest?
No. Asphalt shingles need pitch to shed water, and a low-slope rear section on a Medford two-family doesn’t have it. That area needs a membrane system, priced separately. Whether a quote separates the two roof types is the clearest tell that a contractor actually looked at your building instead of measuring it from an aerial.
