Project Overview

The project encompassed two main areas: an extension to the existing dormer at the rear of the property and a front extension requiring a durable, aesthetically pleasing roofing solution. The goal was to implement a warm deck system and a Sika mechanically fixed flat roof, ensuring both areas were equipped with modern, efficient roofing solutions while preserving the property’s original charm.

Problem Identification

The primary challenges were:

1. Ensuring the rear dormer extension was seamlessly integrated with the existing structure.
2. Implementing a warm deck system to enhance insulation and energy efficiency.
3. Installing a mechanically fixed Sika flat roofing system with custom outlets for the front extension.
4. Reinstating old tiles to maintain the property's historical aesthetic.

Solution Implementation

Rear Dormer Extension:

1. Warm Deck Installation: We started by installing a warm deck system, which is essential for modern insulation standards. This system improves thermal performance, reduces energy costs, and prevents condensation.
2. Sika Single Ply Roofing System: The warm deck was then finished with a mechanically fixed Sika single ply flat roofing system. Known for its durability and weather resistance, Sika provides a robust and reliable roofing solution.
3. Lead Flashings and Tile Hanging: New lead flashings were meticulously installed to ensure a watertight seal, preventing leaks and water damage. Additionally, tile hanging was applied to the dormer cheeks, maintaining the aesthetic consistency of the property.

Front Extension:

1. Sika Mechanically Fixed Flat Roof: For the front extension, the Sika mechanically fixed flat roof was chosen for its reliability and ease of maintenance. Custom outlets were integrated into the system to ensure effective drainage and water management.
2. Reinstating Old Tiles: To preserve the property's character, the old tiles were carefully removed, cleaned, and reinstated. This approach not only maintained the visual appeal but also upheld the historical integrity of the building.

Detailed Implementation

Warm Deck Installation

The warm deck system involved installing insulation above the roof deck, enhancing the thermal performance of the dormer extension. This method is preferred for its ability to keep the roof structure warm, reducing the risk of condensation and improving energy efficiency.

Sika Single Ply Roofing System

The Sika single ply roofing system was mechanically fixed over the warm deck. This material was selected for its high-performance characteristics, including durability, flexibility, and resistance to environmental factors. The mechanical fixing ensures that the roofing system remains secure, even in adverse weather conditions.

Lead Flashings and Tile Hanging

New lead flashings were installed with precision to ensure complete watertightness. This step is crucial in protecting the underlying structure from water ingress. The dormer cheeks were then finished with tile hanging, matching the existing tiles to blend seamlessly with the original design.

Custom Outlets for Front Extension

Custom outlets were designed and integrated into the Sika flat roof system for the front extension. These outlets are vital for effective water drainage, preventing water accumulation and potential damage. The old tiles were reinstated, carefully positioned to maintain the roof's historical look while ensuring modern functionality.

Results and Evaluation

The completion of this project resulted in significant improvements in both the functionality and aesthetic appeal of the property. The rear dormer extension now boasts enhanced insulation and energy efficiency, thanks to the warm deck system and Sika single ply roofing. The front extension benefits from a durable and efficient Sika flat roof with custom outlets, ensuring effective water management.

Reinstating the old tiles preserved the property's historical charm, demonstrating that modern upgrades can coexist harmoniously with traditional aesthetics. The collaboration with Barkham Construction once again proved successful, highlighting the synergy between our teams and the shared commitment to excellence.
