Commercial Roofing
A shop, a storage building or a small plant with a metal roof tends to show its trouble in the same few places: fasteners that have backed out, laps that have opened, a ridge cap that no longer seals and the point where roof meets wall. Alamo's own business overview points to commercial and industrial districts, and Tower Road is a named corridor in the city. We do not assume which roof a given building has, so the first job on any Tower Road property in Alamo, TX is to identify the system and read its condition.
After that comes the water path. Where a stain appears inside tells us little, and we look from the leak backward until we reach the opening. The roof, the wall below it and the ground around the building each get checked in that order, and the photo record shows which of the three the water came through.
Exposed-fastener metal roofs lose their seal at the fasteners. Each screw has a washer that hardens in the sun, and thermal movement works the panel around it until the hole elongates. Standing seam roofs hide the fasteners, and their weak points are seams, clips, penetrations and transitions. Both types can corrode at cut edges and at scratches where the coating has worn through, and corrosion that has reached the base metal is a finding that changes the scope from repair to panel replacement for that run.
We walk the panels rib by rib, press on fasteners, check sealant at laps and look for staining that shows where water has traveled. Where the roof is a standing seam metal system, we also inspect clips and seam closure. Where fasteners are failing across a wide area, a metal roof retrofit can be priced against replacing the panels, and the choice depends on the condition of the purlins and the building's use below.
National Weather Service reports on Hurricane Hanna record street flooding in Alamo during the 2020 storm. Street water is not roof water, but the two are linked in the way a site drains. A yard that holds water, a downspout that discharges against a wall and a dock apron that slopes toward the building all add to the load on the lower walls and the roof-to-wall transitions.
After heavy rain we look at how the building sheds water from the roof to the ground. Gutters and downspouts get checked for capacity and for where they empty. Roof-to-wall flashings are probed for gaps, because water that runs down a wall and meets a failed transition goes inside. The flashing work follows the same logic as flashing failure repair: find the break, repair it, test it.
Transitions between a roof and a vertical wall, a taller roof section or a rooftop unit are the details that fail most often. Movement is concentrated there, water runs onto them from above, and several trades have usually touched them. A transition may be flashed with metal, with membrane or with both, and a repair has to match the method already in place or replace it entirely.
We remove loose sealant, inspect the substrate, fit new flashing and fasten and seal it so that water sheds over the joint rather than into it. Each transition gets a before and after photograph. When the building is a warehouse or a manufacturing plant with interior racking or equipment under the wall, protecting what sits there is part of the plan, and we ask the facility director what cannot get wet.
The county project list identifies Tower Road widening from US 83 to SH 107 and from Business 83 toward Ridge Road in Alamo. Project lists do not say what is happening on the road today, so we check conditions at each address. Lane shifts, driveway closures and construction traffic change where a truck can pull in, how a lift gets set and when a delivery can arrive.
For buildings with yard access, we plan material staging inside the property line where possible. For buildings with a single drive approach, we coordinate with the facility director on the days that approach is clear and keep the log of each day's access. Dust from adjacent work is cleaned from gutters and drains before and after the project. If a driveway closes on short notice, the crew moves the lift to the open side and the log shows the change, so the facility director does not have to chase an explanation for a late start.
Shops and plants run on schedules, and roofing noise, dust and debris matter. We divide the roof into sections that match the building's bays and finish one at a time. Occupied building reroofing uses protected walkways, covered material staging and set hours for loud work.
Each section gets dried in before the crew leaves. If the forecast turns, the plan names what gets covered first. The record holds photographs of each section before, during and after, so the facility director can show a safety manager or an insurer what was done. Fall protection, hot-work controls and traffic separation are set before the first panel comes off, and the plan names who on site holds the keys to the roof access.
A zone-by-zone photo record, a fastener and seam log, flashing repairs with locations, moisture findings where they were taken and a list of items to recheck. Owners with other properties in Alamo, Pharr or elsewhere in the Valley can use one record format across all of them, which lets a manager see at a glance which building has the most open fastener and flashing items and spend the next dollar there.
The washer hardens, the panel moves with temperature and the hole in the metal elongates. Water follows the screw shank into the building. Replacing the fastener with a larger one, or a better washer, is a short-term fix. Widespread failure points to a retrofit or panel replacement, and the walk counts failed fasteners per panel run so the choice rests on a number, not an impression.
Not necessarily. Floor water can come from the ground, the wall or the roof. We trace the path, check roof-to-wall transitions and drainage, and separate roof causes from site causes in the record. If the roof is sound and the site is the source, the record says so, and the owner does not pay for roof work that was never needed.
The condition of the existing panels, the purlins and the insulation, and what the building needs below. A retrofit over sound framing can save tear-off. Corroded or damaged framing points to replacement, since a new roof on weak purlins only moves the problem down a level.
Usually, in phases. We work section by section, protect the interior, schedule loud work around operating hours and close each section daily.
It can change access and delivery times. We confirm conditions, plan around closures and note any change in the log.
