Flex Industrial Roofing in Brockton, MA
Flex buildings leak where two roofs meet. Owners blame the older warehouse side or the tenant who added a unit. The real leak is usually at the step between the office front and the warehouse back, or at a curb one tenant installed and another inherited.
Flex and light-industrial roofing in Brockton, MA is a puzzle of sections. An office front sits lower or higher than the warehouse bay behind it. Rooftop units serve one tenant and not the next. Drains from the upper roof empty onto the lower one. The city gets about 34 inches of snow a year and averages 14.3 mph of wind, and that mix of steps and equipment gives snow and meltwater plenty of places to hide. We map the sections, find which detail is failing and fix it before anyone talks replacement.
Walk the Step Between Office and Warehouse
Where a lower roof butts into a taller wall, a flashing carries the whole load. Snow drifts against that wall. Meltwater and ice collect at the base. The flashing is stressed by movement between two different structures. It is the usual leak point on a flex building.
We check the base flashing, the counterflashing and the sealant along the wall. We look at the membrane where it turns up the wall and at the termination bar or reglet above it. Water that slips behind the counterflashing travels down the wall and drops from the ceiling.
Fix this with new flashing and a proper termination, not a bead of sealant. A flashing failure repair includes the wall behind the flashing. We photograph each step so the owner has a record of which ones are done. If the step has a roof hatch, a ladder or a stair tower, we check that detail too. Access hardware is a frequent source of leaks that no one thinks to look at, because the tenant who uses it never sees the roof.
Count the Units Tenants Added
Multi-tenant buildings collect rooftop equipment. One tenant adds a split system. Another adds an exhaust fan. A third adds a dock leveler heater vent. Each addition is a hole in the roof. Each hole needs a curb, a flashing and a seal.
Walk the roof and count. List every unit, every curb, every pipe and every conduit run. Mark which ones are original and which were added. Added curbs often have thin flashing and no counterflashing. Original curbs may have aged out. A curb and support review covers fasteners, sealant, slope and the condition of the membrane around each base.
Tenants also drag service carts and tools across the roof. That leads to punctures and tears. Walk pads at service routes help. We add them where traffic is heavy. A repaired puncture gets a photo, and the log notes the tenant bay so the same route does not get torn up again.
Split the Roof by Bay, Not by Building
A flex building rents by the bay. The roof should be scoped the same way. If one bay leaks and its neighbors are dry, repair that bay. If a tenant moves out and a new one moves in, that is the time to renew its curbs and flashings.
We draw the roof by bay and give each bay a condition note and a repair list. The owner can then decide what to do now and what to defer. Tenant leases may assign roof costs differently. A bay-by-bay scope makes those conversations easier.
Work moves one bay at a time. Each section is opened, repaired and dried in the same day. Tenants get notice of which bay has work and what hours are noisy. Loading docks and entrances stay clear. Truck traffic at the dock does not stop for a roof, so we stage on the roof or at a corner of the lot. A warehouse roof and a distribution center roof use the same method.
Inspect the Industrial Park Roof You Actually Have
The Avon Industrial Park holds 127 firms on roughly 500 acres zoned for business near Route 24, with a 109,000-square-foot Parker Drive building used for distribution. Taunton's Myles Standish Industrial Park covers more than 800 acres of manufacturing, office, high-tech and distribution buildings. These parks bring distribution, manufacturing and office buildings together. A park name tells us nothing about what is on top of any one building.
So we look. Is the roof membrane or metal? Is the insulation wet? Is the deck sound? When was the last repair? A core cut and a moisture survey answer those. Stoughton's history of manufacturing and shoemaking also left older brick and flat-roof industrial buildings. Their parapets and wall tie-ins need a close look.
Owners with buildings in Avon or Taunton can use the same format at each site. A manager who holds buildings in both parks can then compare roofs on equal terms.
Send Upper Roof Water Somewhere Safe
On a stepped roof, the upper level drains onto the lower one. Water falls from a scupper or a leader and lands on the lower membrane. Over time the landing area wears. Ponds form where the water hits. Ice builds there in winter.
The fix is a splash pad, a leader that runs to a drain or a new scupper. We check each point where upper water meets lower roof. We clear drains, flush leaders and look for ponded water that remains a day after rain. Ponding water at a landing zone often ends with a small fix.
February snow of about 12.8 inches builds drifts at the step. Melt runs to the lowest point. If that point is not a drain, it will leak. Wind at 14.3 mph shifts the drifts and moves them onto the lower roof. A drift on the lower roof adds weight and cuts off a drain. We check for that before the first big storm and again after it.
Cut a Core, Then Plan the Capital
An infrared moisture survey and a few cores answer the real question for each bay: dry or wet? Dry means repair holds. Wet means the repair boundary grows. Core cuts also show the insulation type and the number of layers.
Since October 11, 2024, Massachusetts has used its 10th edition code, 780 CMR, which is based on the 2021 International Building Code. Exposing the deck can bring energy provisions into play. We confirm the permit path before work starts.
Owners with several flex properties can run them as a multi-site roof program, with one report, one ranking and one budget line per building.
Commercial Roofing Questions
Why does a flex building leak at the step?
Two structures move differently there. Snow drifts and meltwater load the flashing. It tears or the sealant fails.
Who pays for a tenant-added curb?
The lease sets that. A bay-by-bay roof scope shows which curbs are original and which were added, which settles most debates. The photo record dates each curb so the owner can show when it went in and what shape it was in.
Can work happen with tenants in place?
Yes. We work one bay at a time and keep docks and doors clear. Tenants get a notice before work starts.
Do industrial park roofs fail differently?
Not really. They fail at seams, flashings and drains. Park location does not change that, though a park with many similar buildings makes it easy to compare roofs and spot the repeat failure.
What do we send to start?
The address, the bay layout if you have it and a photo of the worst spot. We name the real failure before a replacement gets quoted.
