Location: Daytona Beach Shores, Florida
The Twenty-Six Twenty-Six Condominium Association has successfully completed a mansard roof replacement project, restoring the building’s exterior envelope and improving long-term performance in Florida’s demanding coastal environment. Keystone Engineering provided oversight throughout the process to ensure quality, safety, and compliance with engineering and manufacturer requirements.
Project Overview
This project focused on replacing the building’s aging mansard roofing system while addressing hidden structural concerns discovered during demolition. As work progressed, Keystone identified significant deterioration of the roof deck, mansard framing, and related structural components on one of the smaller buildings. The damage was caused by long-term water infiltration, which had compromised the wood structure beneath the roofing system.
Keystone documented the condition through detailed photographs and worked with the Association to determine the appropriate scope of repairs. All corrective work was reviewed and approved by Keystone’s engineering team before installation of the new roofing system continued.
Throughout the project, the Association received regular progress summaries and progress maps, providing clear communication and transparency at every stage.
Scope of Work
The mansard roof replacement included:
Removal of existing asphalt shingles and legacy roofing materials
Installation of self-adhered underlayment over plywood sheathing
Installation of aluminum standing-seam metal roof panels
Installation of aluminum box gutters and downspouts
Integration and tie-in to the existing TPO single-ply roof system
Repairs to deteriorated roof deck and framing members discovered during demolition
By addressing both the roofing system and underlying structural components, the project ensures long-term durability and performance.
Engineering Oversight
Keystone Engineering provided Phase III inspection and construction oversight throughout the project. This included verifying that materials were installed according to manufacturer specifications and the engineering project manual, documenting repairs, reviewing contractor work, and ensuring all corrective measures were completed properly.
Engineering oversight plays a critical role in restoration projects – especially in coastal environments where water intrusion and wind exposure can accelerate deterioration.
Project Outcome
With the installation of the new standing-seam aluminum mansard roof system, the building now benefits from:
Improved resistance to coastal wind and weather conditions
Enhanced waterproofing continuity
Reduced long-term maintenance needs
A modernized exterior appearance
Extended service life of the roofing system
The project was completed in accordance with the Keystone Engineering project manual and applicable manufacturer requirements, ensuring a durable and reliable roofing system for years to come.
