Commercial Roofing
One tenant calls about a wet cardboard box in unit 214, and the manager walks the row to find three more units with water marks on the same side. That pattern is the roof telling the owner where to look: a self-storage building is a long run of identical roofs, so a leak in one bay usually means a fastener line, a lap seam or an end wall transition that repeats down the building. On a storage facility in Edinburg, TX, I start with that repeating detail and follow it along the full length of the row.
The claims side matters as much as the repair. Tenants store furniture, files, inventory and keepsakes, and a roof leak turns into a conversation about damaged goods, insurance and lease terms. A dated photo record of the roof condition protects the owner when that conversation starts.
Water also travels inside a storage building in ways a manager cannot see from the aisle. It runs along a purlin, drips behind a roll-up door header, or enters at the corner where a gutter meets the end wall and then tracks down the partition into a unit that looks dry at the top. We trace the path from the unit side first, then confirm it on the roof, so the repair is made where the water entered and not where it ended up.
Many storage buildings use metal panels or low-slope membranes laid in one continuous run. Metal roofs depend on fasteners with sealing washers and on panel laps with tape or sealant. As panels expand and contract through the day, fasteners back out slightly, washers harden and cracked sealant lets water in along the line. Membrane roofs fail at seams, wall terminations and the places where a downspout or gutter discharges.
Because the construction repeats, a defect on one bay is a clue for the next. We walk the entire length, check every lap and every end wall, and mark the pattern on the roof plan. A leak that shows up in the same relative position in each building tells us the cause is a system detail and not a random puncture. A commercial roof leak repair that treats the whole line costs less over time than chasing one unit at a time.
From May through October the Valley sits in heat-safety season, a stretch of sustained roof-surface heat and solar exposure. A metal panel with no insulation can swing widely in temperature between afternoon and night, and that cycle loosens fasteners and stresses sealants. Dark or aged surfaces also raise the heat that reaches the units below, which matters for tenants storing temperature-sensitive goods.
Tropical weather is a June-to-October matter here. Dolly's gusts were measured at 50 to 70 mph across the county, and a storage building's long eave lines are exposed to uplift in wind like that. After a tropical event we look at ridge caps, eave trim, end wall flashings and any rooftop signage or antennas. A wind damage repair record, with photos taken before temporary work, also gives the owner what an adjuster will ask to see.
We start with the manager's list of units that have reported water, then walk each roof in order from the oldest building to the newest. We photograph every lap, penetration, gutter, downspout and end wall and note which fasteners are backing out.
Where a climate-controlled building has a flat roof with units on it, we check drainage and curb flashing as carefully as a conventional commercial roof. A commercial roof inspection done before the rainy months lets the owner schedule repairs ahead of the storm season instead of after it.
Yes, and the layout makes it easy. Storage facilities consist of separate buildings, so work can be phased by building, with units in the active area cleared by the manager and neighboring buildings left open for tenants. Each building gets its own scope, its own same-day dry-in and its own photo record.
For metal roofs with sound panels, fastener replacement and panel sealing may be enough. For roofs with surface wear but dry decks, a coating restoration can add years. A metal roof retrofit over existing panels fits buildings where the old roof is structurally sound but beyond repair. A full replacement is the answer for roofs with widespread corrosion or wet insulation.
The repair boundary follows the evidence. If water is entering at isolated fasteners or one lap, a repair can stay tight. If panels are corroded through, insulation is saturated or the same building leaks in many places, the owner is paying for repeated repairs that add up to a replacement. The photo record lets the owner compare the two paths with real numbers.
Cost moves with the length of the run, the type of panel or membrane, the number of penetrations, access for lifts and how many units must be vacated or protected. Edinburg's building department reviews a storage-roof replacement against its adopted 2018 codes, which is why insulation and fastening details sit in the first draft of the scope. An owner near the US 281 and I-69C corridor, which runs along the north edge of Edinburg, follows the same process, and the same documentation serves a lender or buyer reviewing the property. Storage buildings share their long, repeating roof lines with warehouse roofing and flex industrial roofing.
A dated photo record of the roof taken before the loss is the strongest evidence, along with the repair log. We provide photographs of each building and a written condition note, so the owner can show when a defect was found and what was done. Insurance questions go to the carrier.
Waiting lets wet insulation spread and puts equipment at risk, so we recommend a temporary dry-in now and a plan for permanent work. The May through October heat season stresses repairs made in a hurry, which is why a temporary fix needs to be followed by a scheduled permanent one.
Oversized or self-sealing fasteners with new washers, butyl tape or sealant at laps, and new trim at eaves and rakes. The right choice depends on the panel profile and the condition of the substrate. We confirm the base is sound before adding new fasteners, because a loose purlin will not hold a new screw.
A coating suits metal that is structurally sound, free of heavy corrosion and well fastened. Panels with rust-through or sagging need a retrofit or replacement. A fastener pull test and a close look at the laps usually settle the question during the inspection, and the owner sees the evidence.
Very little in most buildings. We work one building at a time, keep drive aisles open, and give the manager a schedule that names the affected units. Tenants with sensitive goods can be told in advance, and a dry roof is left behind at day's end so stored items stay protected.
