When a large warehouse roof starts reaching the end of its service life, small roof problems can quickly become operational problems. Leaks can affect inventory, equipment, loading areas, office space, tenant operations, and daily warehouse activity.
This featured example project highlights an 80,000 sq ft commercial warehouse TPO roof replacement in Erie, PA. The goal was to replace an aging low-slope roof system with a new TPO membrane designed to improve roof performance, reduce ongoing leak risk, and give the building owner a clearer long-term maintenance path.

- Project Type: Commercial warehouse roof replacement
- Location: Erie, PA
- Roof Size: 80,000 sq ft
- Building Type: Warehouse / distribution facility
- Roof System: TPO single-ply membrane
The Challenge: Aging Warehouse Roof With Operational Risk
The warehouse roof had reached a point where continued patching was no longer the best long-term plan. Large commercial roofs can develop problems over time from membrane aging, seam wear, drainage issues, flashing failure, rooftop traffic, wind exposure, and repeated weather cycles.
For a warehouse, roof reliability matters because the building is not just empty space. It may protect inventory, equipment, vehicles, materials, racking systems, offices, shipping areas, and loading operations. Water intrusion can disrupt work, create safety concerns, damage stored goods, and lead to repeated emergency service calls.
Before recommending replacement, Quaker State reviewed the roof condition and looked at the practical needs of the building. The goal was to create a replacement plan that addressed the roof system while limiting unnecessary disruption to warehouse operations.
Roof Assessment and Replacement Recommendation
Quaker State began with a roof assessment to identify the main concerns and determine whether repair, restoration, recover, or replacement made the most sense.
The assessment reviewed key roof areas, including:
- Existing membrane condition
- Seams and flashing details
- Ponding water or drainage concerns
- Roof edges and termination points
- Rooftop penetrations and equipment curbs
- Interior leak history
- Access and staging requirements
- Areas that may require insulation or substrate attention
TPO was selected because it is a common commercial roofing option for large flat and low-slope warehouse roofs. It offers a reflective membrane surface, heat-welded seams, broad commercial use, and a practical balance of performance and cost for many warehouse and distribution properties.
The final system details, membrane thickness, attachment method, insulation requirements, and warranty path should be confirmed before publishing.
Scope of Work for the 80,000 sq ft TPO Replacement
The warehouse roof replacement required careful planning because of the roof size, building use, and need for organized project delivery.
The scope of work included:
- Site preparation and project coordination
- Safety setup and rooftop access planning
- Material staging around warehouse operations
- Existing roof preparation or tear-off, as required
- Replacement of wet or damaged areas, if applicable
- Insulation or cover board installation, if specified
- TPO membrane installation across the roof field
- Heat-welded seam work
- Flashing around curbs, penetrations, walls, and roof edges
- Drainage detail review
- Final walkthrough and cleanup
On a project of this size, the details matter. Large roof fields are important, but many leaks start at roof edges, seams, penetrations, drains, and rooftop equipment. Those areas received focused attention during the replacement process.
Project Challenges and How They Were Managed
The main challenge was coordinating a large-scale roof replacement while respecting the building’s daily use. Warehouse projects often require planning around loading areas, employee access, delivery routes, stored materials, and equipment movement.
Potential project challenges included:
- Large 80,000 sq ft roof area
- Weather windows in Erie
- Material staging and access
- Roof drainage concerns
- Rooftop penetrations and equipment
- Maintaining safe work zones
- Coordinating roof work around warehouse operations
Quaker State managed the project with clear communication, organized staging, and a roof replacement plan built around the facility’s needs. Weather was also an important factor because Erie-area commercial roofs are exposed to rain, wind, snow, ice, and freeze-thaw cycles throughout the year.
Timeline, Scheduling, and Building Coordination
The project was scheduled around the needs of the building and the roof replacement scope. For a warehouse roof of this size, timeline planning is important because material delivery, crew coordination, weather, tear-off or preparation work, membrane installation, and final detailing all need to happen in the right order.
Daily coordination helped keep the project moving while giving the building contact visibility into work progress, access needs, weather delays, and next steps.
The Result: A New TPO Roof System for Long-Term Warehouse Protection
The completed project delivered a new TPO roof system for the 80,000 sq ft warehouse, giving the owner a better path forward than repeated patching and short-term repairs.
Project outcomes included:
- New TPO membrane installed
- Roof details addressed around seams, edges, penetrations, and drainage areas
- Improved long-term roof planning
- Reduced dependence on repeated leak repairs
- Clearer maintenance and inspection path
- Closeout documentation for the building owner, if applicable
- Warranty path established, if confirmed
This type of project shows why large commercial roof replacements should be planned carefully. The right system, installed with attention to detail, can help protect warehouse operations and reduce roofing uncertainty for years to come.
What Does a Warehouse TPO Roof Replacement Cost?
The cost of an 80,000 sq ft warehouse TPO roof replacement depends on several factors, including the existing roof condition, tear-off requirements, insulation, membrane thickness, attachment method, roof access, drainage improvements, edge metal, warranty requirements, and whether wet or damaged materials need replacement.
