Commercial Roofing in Sharon, MA
A roof seldom fails untouched. It fails when somebody adds to it. A new rooftop unit, a satellite dish, a row of solar brackets: each one is a hole, and the hole is usually cut by a trade that does not roof, then sealed with whatever was on the truck. Sharon, MA covers about 23.3 square miles of land, with Route 27 running through the center of town and connecting to Route 1. Whatever sits on its commercial roofs, the likeliest leaks start where something was added.
Place the roof in the town it serves
Sharon had 18,575 residents at the 2020 census, and MBTA commuter rail on the Providence/Stoughton Line stops in town. Water covers about 3.56 percent of the town's area. The freeze-thaw, wind and wet snow of eastern Massachusetts reach the roofs in town.
We do not assume what any building looks like. A first visit tells us the deck, the layers, the equipment and the history of repairs. That visit gives the owner a map of the roof as it exists, not as the drawings say it was built. A roof that has taken added equipment over the years rarely matches its original plan.
Fix the hole someone else cut
A cable run, a conduit, a vent pipe or a new unit curb usually goes in through the membrane. The trade that does the work seals it with whatever is on the truck. Sealant ages. The boot cracks. A year later the ceiling stains, and the roof gets the blame.
The repair is rarely dramatic. We cut out the failed penetration, rebuild the penetration flashing with the right boot or curb detail and weld or bond it to the membrane. Then we mark it on the roof plan with a photograph and the date. The next person who touches that spot knows what is under the boot and who installed it. A penetration done right lasts. A penetration done with sealant alone lasts until the next thaw. Nearby Brockton, MA logs around 34 inches of snow a year with a -19 degree low, and sealant that cannot move with the cold does not last.
Count every hole on the first walk
The first walk is an inventory. We list every penetration and every piece of equipment on the roof, then test each one.
- Pipe boots and conduit penetrations, checked for cracks and open collars.
- Rooftop unit curbs and supports, with flashing height and cap seals.
- Abandoned supports, brackets and capped pipes left from earlier work.
- Roof drains and overflow, flushed to show flow.
- Shaded or damp areas, where moss and algae show standing moisture.
The inventory helps in two ways, and the owner keeps a copy. It finds the leak, and it shows what the next trade will add. A building with a dozen old penetrations is a building that needs a rule: no new roof work without notice to the roofer. We put that rule in writing for the owner, along with a one-page list of who to call. Contractors who know the roof is watched cut cleaner, seal better and tell us about the work.
Repair the details, upgrade where it pays
Many commercial buildings need detail repair for years before a replacement comes up. Rebuild the flashings, clear the drains, weld the seams and keep records. That is the cheapest path that holds. A commercial roof repair scope lists each item with a price.
Upgrade when the layers say so. If insulation is wet or the membrane has aged out, replace the section or the roof. If the building will take rooftop solar, plan for it during the replacement. Solar-ready roofing sets the membrane, the cover board and the attachment points so panels do not cut the roof later. A coating, such as silicone, can extend the life of a sound roof that holds water in spots. It needs a clean, dry surface and sound seams, so the repairs come first and the coating goes on last, after a test cut shows dry insulation beneath.
Price the repair by what drives cost
Penetration repairs are priced by count and access. Ten boots on an easy roof cost less than three curbs on a roof with limited access. The wet insulation around a failed penetration adds to the bill, since it comes out and goes back in. Roof size, number of details, layers to remove and lift position set the rest.
We list each item with a price, so the owner can approve some and defer others. A rebuilt curb costs more than a new boot, and a new boot costs more than a bead of sealant. The sealant is the cheapest and it fails first. Waiting adds the wet insulation, the ceiling and the mold. That is the real price of the cheap fix: it buys one season and hides the next leak.
Timing helps. Work done in the dry months cures well and leaves time to check the result before winter. Material lead times are short for boots and flashings and longer for curbs, so a spring order avoids a fall scramble.
Coordinate the trades on the roof
Most roof leaks come from the trades that use the roof. We set up a simple process. Any contractor who needs to cross or cut the roof notifies the owner. We mark the route, protect the membrane and handle the penetration. The charge is small. The leak it prevents is not.
For public and mixed-use buildings, schedule matters. School and municipal work follows a calendar. Offices want quiet hours. Small retail wants the front clear. We plan the lift location, the material path and the close-in time with the building manager. The same coordination rule applies on commercial roofs in Norwood and Canton.
Allow for winter, wind and the current code
Snow drifts around rooftop equipment and hides cracked boots. The thaw reveals them. A fall walk finds them first, while the sealant can still be reworked in dry weather. Winds in nearby Brockton average 14.3 mph and nor'easters can reach hurricane force, which is why equipment bases and edge metal must be tight.
Any replacement or larger addition in Sharon is reviewed under 780 CMR, the Massachusetts 10th edition built on the 2021 IBC. It took over on October 11, 2024 and has stood alone since June 30, 2025. The permit path gets confirmed with the town before material is ordered.
Commercial Roofing Questions
Why did my roof start leaking after a unit was installed?
The curb or the penetration around it is the first suspect. We check the flashing, the cap seal and the fasteners, then water-test the joint. A proper curb detail fixes it.
Can I put solar panels on a flat commercial roof?
Often, if the deck and membrane can carry the load and the attachment is flashed properly. We check the roof's age and condition first. A roof near the end of its life should be renewed before panels go on.
What does moss on a roof mean?
Standing moisture, usually from shade, poor drainage or both. Moss holds water against the membrane and shortens its life. We clear it and fix the drainage that let it grow.
Should I require roofer sign-off for any rooftop work?
It is a good rule. A short notice and a roofer's seal on each penetration costs little and prevents most trade-caused leaks.
How quickly can a leak be stopped?
The line is answered around the clock, holidays included, and the opening gets secured before anything permanent is planned.
