Project Description
A large flat roofing surface in Columbia, Maryland, required a new protective membrane. A1 Roofing’s KangaRoof completed a flat roof recovery project that included preparing the existing surface, installing a new TPO membrane, and carefully sealing the membrane seams.
The project focused on creating a continuous roofing surface across the extensive low-slope roof while completing the seams and transitions throughout the installation area.
Project Overview
- Location: Columbia, MD
- Service performed: Flat roof recovery
- Roofing system: TPO membrane
- Work completed: Surface preparation, membrane installation, and seam sealing
- Roof type: Flat or low-slope roofing system
Preparing the Existing Flat Roof
Before installing the new membrane, the crew prepared the existing flat roof surface.
Proper preparation was necessary to create a suitable base for the new TPO roofing material. The crew worked across the roof to address the installation area and prepare it for placement of the membrane sheets.
The project photos document the preparation process and show the scale of the flat roofing surface.
Installing the New TPO Membrane
After the surface was prepared, A1 Roofing’s KangaRoof installed the new TPO membrane across the roof.
The membrane sections were positioned to cover the flat roof area and create a continuous new exterior surface. The crew carefully aligned the material as installation progressed across the property.
TPO is commonly used for residential and commercial low-slope roofs because it provides a practical single-ply roofing surface. Property owners considering a similar system can learn more about available flat roofing services in Columbia, MD.
Sealing the TPO Membrane Seams
Once the membrane sections were positioned, the crew sealed the adjoining seams.
Seam work is an important part of a TPO roofing installation because the individual membrane sections must function together as one continuous roofing surface. The crew worked through the roof area to complete each connection and transition.
The project included:
- Preparing the existing flat roof surface.
- Positioning the new TPO membrane.
- Installing the membrane across the roofing area.
- Sealing the adjoining membrane seams.
- Completing the details throughout the recovered roof surface.
The Completed Flat Roof Recovery
The flat roof recovery provided the property with a new TPO membrane surface without adding unsupported work to the documented project scope.
A1 Roofing’s KangaRoof prepared the roof, installed the membrane, and completed the seams across the extensive flat roofing area. The project photos show the crew working through each stage of the installation.
