Self-Storage Roofing in Brockton, MA
A tenant calls about wet boxes in unit 114. The manager blames the unit door. The door is rarely the cause. Water came in through a fastener, a lap or an eave, ran down a wall or along a purlin and dripped into the unit. The roof is the cause. The door is where the tenant saw it.
Self-storage roofing in Brockton, MA is a volume problem. A facility has long rows of similar roofs, hundreds of fasteners and eaves with no gutters or small ones. One weak detail repeats across a whole row, the same way it does on a warehouse roof or a flex industrial roof. The city takes about 34 inches of snow a year, and freeze-thaw works every lap and screw. We find which detail is failing, count how many repeat and price the fix by the row.
Trace the Wet Unit Back to the Roof Row
Start with the unit list. Mark every wet unit on a site plan. Look for the pattern. Units along one wall suggest an eave or wall flashing. Units at the same end of a row suggest a rake or a ridge. Units scattered along the middle suggest laps or fasteners.
Then go up. Walk the roof above the cluster. Check laps, fasteners, ridge caps, eave closures, wall transitions and skylights if there are any. Water on a metal roof runs along the panel rib or the purlin before it drops. The drip in the unit may sit several feet from the opening.
We hose test the suspects one at a time. The one that leaks goes on the repair list. A facility manager gets a roof plan with every wet unit and every confirmed entry point marked. That sheet is worth more than a verbal diagnosis. It also shows which rows are clean, so money is not spent where nothing is wrong.
Reseal Fasteners Before Replacing Panels
On exposed-fastener metal roofs, the screw is the weak point. Each one has a rubber washer that hardens in sun and cold. Roof movement works the screw loose and the hole elongates. Water follows the screw shank in. The panels are not always shot.
A fastener program replaces the worst screws with larger ones and new washers, reseals laps and renews butyl or sealant at the ridge and eave. It costs far less than new panels and works while the panels are sound. We count failed fasteners per panel run. If the count is high across most runs, the panels or the substrate need attention. If it is low, a reseal buys years.
Look at the seam and lap condition at the same time. A panel with rust at the cut edge or a stretched fastener hole will not hold a new screw. Those panels get replaced. The rest stay. The record shows the failed-fastener count for each run, so the owner sees exactly where the money went.
Move Snow Away From the Doors
Metal roofs shed snow fast. A slab can slide off an eave onto a door, a walkway or a parked vehicle. Brockton's February snowfall of about 12.8 inches, plus ice, makes this a safety issue, not just a roof issue.
Snow retention bars or guards on the right slopes hold snow in place so it melts slowly. Eave gutters carry meltwater away from doors. Without them, water drips on the apron and freezes. Ice at a door causes falls and damaged rollers.
We check where snow lands now. We look at gutter condition, downspout discharge and the slope of the ground at each door line. If snow and ice are a repeat problem, the fix may be retention hardware and a gutter run. That is a roof scope, and it ties into edge metal and gutter work.
Log Every Wet Unit and Every Repair
Tenants file claims. Managers need records. We build a leak log tied to unit numbers. Each entry lists the date, the unit, the likely source and the repair. A repaired fastener gets a photo. A resealed lap gets a photo. A hose test result gets noted.
That log helps in three ways. It shows which parts of the roof leak most. It supports tenant conversations with facts. It shows an insurer or lender that the owner acted. A property with a clear log is easier to finance, insure and sell.
Wind adds events. Brockton averages 14.3 mph, and nor'easters can bring hurricane-force gusts. After a big wind, we recheck ridge caps, rake trim and eave closures. Loose trim is how a good roof starts to leak. Ridge vents and skylight curbs, where present, get the same check.
Work Row by Row With the Gate Open
A storage facility cannot shut down. Customers come and go. The gate stays open during business hours. We plan around that. One building or one row is opened, repaired and closed. The lift and truck sit in a lane that leaves tenant access clear. Tenants get a notice of which row will have work on which day. Moving a few boxes away from a wall on the day of work is a small ask, and a posted notice gets that done without a lot of phone calls.
Staging happens on the roof or in a corner of the lot. Debris is bagged and carried out. Sealants and primers stay away from open unit doors. We ask the manager where tenants drive, where large vehicles park and where an ambulance or fire truck would need to turn.
Short winter days limit the work. Adhesives and sealants cure poorly in cold. We schedule bigger resealing jobs for spring through fall and use fall walks to find the work. If the panels are past repair, a metal roof retrofit goes over them.
Pick Between Coating, Retrofit and Replacement
Three paths exist for an aging storage roof. A coating over a sound metal roof can extend life if the panels are not rusted through and the fasteners are tight. A coating system is a surface, not a repair. A retrofit puts a new metal roof over the old one. Replacement strips and starts fresh.
Condition decides. A core cut or a panel check shows whether rust has gone through. If the base metal is sound, a coating makes sense. If rust is widespread, a retrofit or replacement is safer. Standing seam metal hides the fasteners and cuts leaks at screws, which is why owners pick it when they replace.
A larger storage roof scope may need a permit and an energy review under the state code that took effect October 11, 2024. We confirm the path first. An owner with a facility in Raynham or Easton gets the same logging format.
Commercial Roofing Questions
Why do units leak when the roof looks fine?
Water enters at a fastener, lap or eave and travels. The drip can be feet from the opening. We trace it back.
Is a coating enough to stop screw leaks?
Only if the panels and fasteners are sound. A coating over a loose screw seals nothing. Fix the screws first, then decide whether the surface needs a coat. A coating also hides nothing: rust at the cut edges still shows on the next walk.
Can you work with the gate open?
Yes. We work row by row, keep tenant lanes clear and post notices of the work schedule.
How do we handle tenant claims?
Keep a leak log with unit numbers, dates and repairs. Photos show what was fixed. It backs up your response.
What do we send to start?
The address, a site plan if you have one and a photo of the worst wet unit. We name the failure first and leave replacement pricing for later.
