Project Description
A flat roof in Columbia, Maryland, had reached the point where a complete replacement was needed rather than another surface-level repair.
A1 Roofing’s KangaRoof removed the existing roofing materials, exposed the underlying roof base, and prepared the surface for installation of a new flat roofing system.
Project Overview
- Location: Columbia, MD
- Service performed: Flat roof replacement
- Roof type: Flat or low-slope roof
- Main work: Complete tear-off and roof base preparation
- New system: New flat roofing system
Removing the Existing Flat Roof
The project began with a full tear-off of the existing flat roofing materials.
Instead of installing another layer over the older roof, the crew removed the existing system to gain direct access to the surface underneath. This allowed the condition of the roof base to be addressed before the new roofing installation began.
Preparing the Roof Base
Once the old roofing materials had been removed, A1 Roofing’s KangaRoof cleared and prepared the exposed base.
The project photos show the crew working across the open low-slope roof during this stage. Proper preparation created a clean working surface for the new roofing system and ensured that the replacement was being installed from a properly prepared base rather than over worn materials.
The documented work included:
- Removing the existing flat roofing materials.
- Clearing debris from the roof area.
- Exposing the underlying roof base.
- Preparing the surface for the replacement system.
- Continuing with installation of the new flat roof.
Installing the New Flat Roofing System
After the tear-off and preparation were completed, the roof was ready for the new low-slope roofing system.
The original project information does not identify the specific membrane type, manufacturer, insulation system, or fastening method, so those details should not be added to this case study.

The Completed Result
This project replaced an aging flat roofing system from the base upward rather than covering the existing materials.
By completing a full tear-off and preparing the exposed surface before the new installation, A1 Roofing’s KangaRoof created the proper starting point for the replacement flat roof.
