Project Description
A residential property in Columbia, Maryland required a roof repair that extended below the visible roofing materials. After the old and worn materials were removed, the crew from A1 Roofing’s KangaRoof accessed damaged plywood within the roof assembly.
The damaged plywood was replaced, new insulation was installed, and the repaired area was prepared for the next stage of the roofing installation.
Project Overview
- Location: Columbia, MD
- Property type: Residential property
- Service performed: Roof repair and roof decking work
- Work completed: Removal of worn materials, damaged plywood replacement, new insulation installation, and preparation for new shingles
The Problem
The existing roofing materials covered sections of damaged plywood that needed to be addressed before the roof could be prepared for new shingles.
Because the problem extended beneath the exterior roof covering, replacing only the visible materials would not have completed the required repair. The crew first needed to open the affected area and work on the underlying roof assembly.
Removing the Old Roofing Materials
A1 Roofing’s KangaRoof began by stripping away the old and worn roofing materials. This provided access to the plywood beneath the roof surface and allowed the crew to identify the damaged sections.
The affected plywood was then removed so that unsuitable material would not remain beneath the new roofing system.
Replacing the Plywood and Installing New Insulation
New plywood was installed in place of the damaged sections and carefully aligned with the surrounding roof deck.
The crew also installed new insulation within the opened roof area. After the plywood and insulation work was completed, the roof surface was secured and prepared for new shingles.
This project addressed the concealed components of the roof rather than simply covering the existing damage.
The Result
The repaired area received new plywood decking and insulation, creating a properly prepared base for the next stage of the roofing work.
The project photographs document the process from removal of the older materials through replacement of the damaged plywood and preparation of the roof for new shingles.
