Project Overview
The team at RTG Solutions completed a targeted commercial roof repair at Park Hills Plaza after we identified multiple membrane deficiencies during the site visit. The primary issues were active leakage at a parapet wall corner, a puncture hole in the roof membrane, and membrane tearing at the inside corners around a unit’s base flashing. We know from experience that it is those kinds of failure that turn into “mystery leaks” because water travels laterally under stress and shows up far from the entry point.
Our team was brought in to correct known deficiencies in the membrane and detail work, then close them out in a way that ensured future serviceability. We installed new membrane patches at the affected areas and sealed the radiuses and seams, restoring continuity at the locations most likely to reopen if the details are not rebuilt correctly.
Location
At RTG Solutions, we know firsthand that commercial flat roofs in Altoona frequently take a steady beating from wind-driven rain, freeze-thaw cycling, and sharp seasonal temperature swings that stress seams, corners, and transitions. The field of a membrane roof can look totally fine while the details quietly fail, especially at parapet corners and around rooftop equipment where movement, vibration, and thermal expansion concentrate stress.
For retail and plaza properties like the Park Hills one in Altoona, roof issues become operational problems fast! Even small membrane failures can create recurring interior risk, tenant disruption, and escalating repair costs if the entry points are not corrected cleanly. This project focused on eliminating the obvious breach locations and reinforcing the details so the roof performs predictably through the next set of seasons.
Repairs and Materials
Our repairs were centered around membrane roof patching and sealed detailing at known failure points. Our team installed new patches at the parapet wall corner where active leakage was observed, then sealed the radius and seams to keep water from tracking behind the flashing details. A puncture hole in the membrane was patched and sealed to restore a continuous weather barrier, since punctures are direct entry points that typically worsen with foot traffic and ongoing exposure.
Our team also addressed tearing at the inside corners around the unit’s base flashing, which is a classic flat-roof problem area. Corners and radiuses are where membranes tend to split first when the detail is underbuilt or when movement keeps working the same spot. Patching those tears and sealing the radiuses can be the difference between a “temporary stop” and a repair that actually holds.
About the Client
Park Hills Plaza in Altoona needed the roof to return to normal function without unnecessary scope creep. In commercial roofing, the goal is pretty simple: stop repeat water entry, stabilize the vulnerable details, and keep the repair serviceable so future inspections and maintenance are straightforward. Our team approached this as a defined commercial roof repair, focused on the membrane breach points that create repeat issues and the detail work that determines whether the repair lasts.
Project Scope
- Install a new membrane patch at the parapet wall corner deficiency and seal the radius and seams.
- Patch and seal the puncture hole in the roof membrane to restore continuous waterproofing.
- Patch over membrane tears at the inside corners around the unit’s base flashing and seal around the radius.
- Complete closeout with clean, watertight detailing designed to reduce repeat leak risk.

Quality Highlights
Commercial roof repairs only matter if the details stop the same failure from happening again. At Park Hills Plaza, the work focused on the points that actually cause repeat calls on flat roofs: a puncture hole in the membrane, tearing at inside corners around base flashing, and a parapet corner detail that was leaking. The highlights below reflect how the repair was closed out to restore continuity, reinforce stress points, and keep the finished work easy to inspect and maintain.
Quality repairs at the real failure points
Flat roof problems usually start at corners, radiuses, and transitions, not in the open field. This repair corrected the puncture and the corner tearing, then rebuilt the sealing at the parapet corner so water is kept outside the system instead of being allowed to work behind it.
Membrane patching done for durability
A patch is only as good as its edges and the sealing around it. RTG’s work emphasized sealed seams and radiuses, which is where many “repairs” fail later even when the patch itself looks fine on day one.
Strong closeout to support future maintenance
Commercial roof repairs have to be inspectable and maintainable. The patched and sealed areas were closed out as practical repair details, meaning a future technician can evaluate them quickly and service them without guesswork.
