COMMERCIAL ROOFING CASE STUDY
TPO Roof Replacement Greensboro NC
Hidden Deck Rot Discovered During Tear-Off
This Greensboro, NC commercial roofing project started as a straightforward TPO roof replacement. Once Sunny Sky Roofing began the tear-off, significant wood rot was discovered along the roof deck edges beneath the existing roofing system. The compromised decking had to be removed and rebuilt before the new roof could be installed properly.
PROJECT OVERVIEW
Greensboro, NC Commercial TPO Roof Replacement
THE EXISTING ROOF
The Greensboro project began as a straightforward commercial TPO roof replacement. The existing roofing system had reached the end of its service life, and the building owner wanted a new roof installed correctly rather than simply covering the existing problems.
The first step was a complete tear-off. Removing the existing roofing system allowed our team to inspect the structural deck instead of assuming the substrate was still in good condition.
WHAT WE FOUND UNDER THE OLD ROOF?
Once the existing roofing system was removed, the condition of the roof deck became clear. Our team discovered significant wood rot along the roof deck edges that had not been visible from the surface.
Rather than installing the new membrane over compromised material, the affected decking had to be removed and rebuilt. Addressing the damaged substrate first gave the new roofing system a sound surface to be installed over.
REBUILDING THE DAMAGED ROOF DECK
REBUILDING THE DAMAGED ROOF DECK
Once the damaged areas were identified, Sunny Sky Roofing removed the compromised decking rather than installing the new roofing system over deteriorated material.
The affected roof-edge areas were rebuilt to provide a solid substrate for the new roofing assembly. This additional work addressed the underlying condition before the membrane installation began.
With the roof deck repaired, the project could move forward with the installation of new insulation and the mechanically attached TPO system.
NEW INSULATION & TPO INSTALLATION
NEW INSULATION & TPO INSTALLATION
With the damaged roof deck repaired, the roofing assembly could move forward on a sound substrate. New insulation was installed as part of the replacement system, helping prepare the roof for the new membrane.
Sunny Sky Roofing then installed a mechanically attached white TPO roofing system across the prepared roof area. The membrane was secured to the assembly and detailed throughout the roof to create a continuous weather-resistant surface.
The installation also included attention to perimeter conditions and roof details so the new system could perform as intended across the commercial building.
ROOF PERIMETER & DETAIL WORK
With the new TPO membrane installed, Sunny Sky Roofing completed the perimeter and roof-edge detailing needed to secure the roofing assembly and protect vulnerable transition areas.
Particular attention was given to the roof edges and other termination points where the membrane meets existing building components. These details help maintain continuity across the roofing system and reduce potential pathways for water intrusion.
Completing these areas as part of the installation helped ensure the new TPO system was properly integrated across the commercial roof rather than leaving critical edge conditions unresolved.
PROJECT OUTCOME
After addressing the deteriorated roof decking and installing a new mechanically attached TPO membrane, the Greensboro commercial property received a renewed roofing system designed to provide reliable weather protection and improved long-term performance.
COMMERCIAL ROOFING CASE STUDY
Aging commercial roofing systems can hide serious problems beneath the surface. If your building needs a roof inspection, repair, or replacement, Sunny Sky Roofing can help identify the right solution.
Experienced in commercial roof replacement, TPO roofing, and roof deck repairs.
A successful commercial roof replacement starts with more than a new membrane. Proper tear-off, roof-deck inspection, substrate repairs, and professional TPO installation can help ensure the new roofing system is built on a sound foundation.
If your commercial roof is aging, damaged, or approaching the end of its service life, Sunny Sky Roofing can evaluate the existing system and recommend the right path forward.
This Greensboro project shows why a commercial roof replacement should begin with a careful inspection of what lies beneath the existing system. From hidden deck deterioration to new insulation and mechanically attached TPO, every stage matters.
Let Sunny Sky Roofing evaluate your commercial roofing system and help you determine the right solution for your building.
A professional roof inspection can help identify hidden damage, aging materials, leaks, and potential structural concerns before they become more costly problems. Sunny Sky Roofing evaluates your commercial roofing system and recommends the right next steps based on its condition.
