Commercial roofing in Plano, no shortcuts
Renovacore Builders LLC repairs and maintains flashing, penetrations, and full commercial roof systems for Plano businesses.
Renovacore Builders LLC handles commercial roofing for Plano businesses, including flashing repair around rooftop units, full roof installation and replacement, and ongoing maintenance. Flashing failures around vents, curbs, and rooftop equipment are one of the most common sources of leaks on a commercial roof, and they are also one of the easiest to catch early with a proper inspection. We serve Plano as part of our coverage across the DFW Metroplex.
Why does my Plano commercial roof keep leaking around the rooftop units?
Flashing around rooftop HVAC units and curbs works loose over time as the building settles and expands and contracts with temperature swings. Once the seal breaks, water finds a path along the curb and into the roof assembly below, and the leak inside is often several feet from the actual entry point. Most roof leaks start at flashing rather than in the open field of the roof, so every penetration and transition needs to be checked, not just the one closest to the stain.
Warning signs to watch for
Loose or lifted flashing at rooftop units
Curbs and flashing around HVAC equipment shift as the building moves. Once the seal breaks, it stays broken until it's repaired.
Water staining near roof penetrations
Staining on the interior ceiling near a vent, unit, or pipe usually traces back to the flashing directly above it.
Cracked pipe boots or vent seals
The rubber collar around a plumbing vent dries out and cracks well before the rest of the roof shows its age, and it's an easy point of entry for water.
What usually causes it
Building movement over time
Thermal expansion and settling work flashing loose gradually, which is why older flashing needs periodic checking even without an active leak.
Improper flashing installation from a prior job
Flashing that wasn't properly stepped or sealed the first time tends to fail sooner and repeatedly in the same spot.
Wear from an aging roof surface
A roof nearing the end of its service life often has multiple flashing points failing at once rather than a single isolated leak.
What this means for Plano building owners
Nearby McKinney recorded 34,134 hail loss claims from 2017 through 2019, placing it among the National Insurance Crime Bureau's top U.S. cities for hail claims over that period, a reflection of how exposed North Texas roofs are to hail in general. For flashing and rooftop equipment, that volume of hail claims is a reminder that even minor storm damage can loosen seals that were otherwise holding.
In Plano itself, U.S. Census data from the 2020 to 2024 American Community Survey put the median year a home was built at 1993, with about 64% of the housing stock built between 1970 and 1999. Many commercial buildings in the area date from a similar period, which means original flashing details are often decades old and due for a closer look.
We do the same commercial roofing work in Sachse and Frisco.
What happens on the visit
We inspect every flashing line and penetration on the roof, not just the one nearest the interior stain, and check the attic or interior deck side where accessible. We water-test any suspect area when the source isn't obvious from a visual check alone. Then we repair or reseal the flashing and explain what we found, along with a free estimate.
The cost of waiting
A single loose flashing point rarely stays isolated. Water that gets behind a curb or vent seal can travel along the deck and show up as a stain well away from the actual source, so the longer it sits, the more of the roof assembly gets wet before anyone notices. Catching it at the flashing stage keeps the repair small.
How long does commercial roof flashing repair take in Plano?
Most flashing repairs are completed in a single visit once the source is identified, and larger buildings with multiple rooftop units may take longer depending on how many penetrations need attention. We give you a clear timeline once we've inspected the roof.
