About Boxborough Roofing Contractor
Mark Sullivan, Owner-Operator — Roofing Boxborough and Sixteen Neighbouring Towns Since 2014
Boxborough Roofing Contractor works out of 859 Massachusetts Ave in Boxborough. The business is small on purpose. Mark Sullivan inspects the roofs, writes the quotes and is on site for the work, which means there is one person accountable from the first phone call to the final walkthrough and nobody in between whose job is closing.
The work is shaped by what this corner of the state actually has on it — fifteen Middlesex towns and two in Worcester County, running from Tyngsborough on the New Hampshire line down to Sudbury, and west to Harvard and Bolton. A lot of 1960s to 1990s ranches, capes and colonials with shallow overhangs and thin insulation at the eaves, which are the exact conditions that produce ice dams every February. Antique houses in Harvard, Concord and Groton with additions joined at odd angles, where the leak is almost always at a step flashing that was reused one roof too many times. Mill-era two-families in Maynard and Hudson packed close together, where staging matters as much as shingles. And on the open hills toward Bolton and Groton, wind exposure that lifts ridge caps and strips granules off south and west slopes years before the warranty says it should.
- Owner-operated — the person who inspects your roof runs the job and answers the phone
- Roof and attic inspection before any number is quoted, not a measurement from the driveway
- Itemized written quotes including a decking allowance, so rot is priced before it is found
- Building permits filed and inspections coordinated on every replacement
- Installed to 780 CMR: ice barrier at the eaves, no third layer of shingles, ventilation that keeps your shingle warranty intact
- Boxborough plus sixteen neighbouring towns across Middlesex and Worcester counties

On-site quotes & advice
How a job actually runs, start to finish
1. Tell us what the roof is doing
Call (978) 797-1851 or send the form. Tell us what you are seeing — a ceiling stain, missing shingles after a wind event, or a roof that has simply reached twenty-five years. We book inspections Monday to Friday 8am to 6pm and Saturday 9am to 2pm, and active leaks move to the front of the list.
2. Roof and attic inspection
We walk the roof where it is safe to, then go into the attic. Most of what decides a repair-versus-replace call is visible from underneath: daylight at the ridge, frost on the sheathing nails, compressed insulation at the eaves, a bath fan venting into the attic instead of through the roof. Ground-only estimates miss all of it.
3. Photos and an itemized written quote
You get photographs of what we found and a written quote broken into line items, including a decking allowance so a rotted board does not become a surprise invoice. If repair is the honest answer on a roof with ten years left, that is what the quote says.
4. Permit, scheduling and site protection
For replacements we file the building permit with your town — Boxborough through PermitPro, the surrounding towns through their own building departments — and coordinate the inspection. Tear-off happens on a dry window; we tarp and protect landscaping, gutters and any wetland buffer on the property.
5. Installation, cleanup and walkthrough
Ice-and-water shield at the eaves and valleys, synthetic underlayment, new step and counter flashing rather than reused metal, proper ridge and soffit ventilation, then a magnet sweep of the drive and lawn. We walk the finished job with you and leave the written scope of what was done.
A Boxborough Roofer Who Shows You the Roof, Not a Brochure
We run this business out of 859 Massachusetts Ave in Boxborough, which means the person who inspects your roof is the person who answers the phone and stands behind the finished work. Most of what we do is unglamorous: ice dam damage along north-facing eaves, flashing that failed at a chimney, a 1980s roof on its second layer of shingles that Massachusetts code will not let us cover a third time.
-
We Quote to the Code, Not Around It
Massachusetts code (780 CMR) requires an ice barrier membrane running from the eave edge to at least 24 inches inside the exterior wall line, and it caps asphalt roofs at two layers. We quote to that standard, and we tell you when a roof already has two layers on it — because that changes the price before we start, not after.
-
Permits Filed and Tracked for You
Boxborough runs permits through the PermitPro portal, and the building department at 29 Middle Road will not issue one without a current certificate of liability and workers' comp insurance on file. We file the application and handle the inspection scheduling on replacement jobs so you are not chasing paperwork.

Sixteen Neighbouring Towns, One Crew
Ice dams on shallow-pitch ranches near Flerra Meadows behave differently from wind-lifted ridge caps on the exposed hills in Harvard and Bolton. Boxborough plus sixteen neighbouring towns, one crew — we have seen how each town's housing stock fails and we inspect for that specifically.
-
Line-Item Pricing With No Blank Spaces
You get line items: tear-off, decking allowance, ice-and-water shield, underlayment, shingles, flashing, ventilation, disposal, permit. If we find rotted sheathing under the old roof we show you the board before replacing it and the allowance in your quote covers it.
