Flat Roof Replacement – West Sussex
We recently completed a full flat roof replacement in West Sussex, where the existing roof system had deteriorated to the point that a complete strip and rebuild was the only reliable long-term solution.
Once the old covering was removed, it revealed widespread issues within the roof structure, including aged decking, failed insulation, and areas requiring structural improvement to restore the roof properly.
Rather than carrying out short-term patch repairs, we stripped the roof back and rebuilt it with a new solid deck and a high-performance waterproofing system, ensuring the roof was brought back up to modern standards.

Scope of Works
• Full removal of the existing failing flat roof covering
• Strip back to expose the full roof structure
• Removal of defective and deteriorated materials
• Replacement and strengthening of timber work where required
• Installation of new roof decking to create a strong, level base

• Preparation of all perimeter edges and abutments
• Installation of a 3-layer high-performance torch-on felt roofing system
• Detailing around the chimney, upstands, and perimeter for full weather protection

System Build-Up
The new flat roof was completed using a durable 3-layer torch-on felt system, designed to provide long-lasting waterproof protection and reliable performance in all weather conditions.
This modern felt roofing system offers:
• Excellent durability and lifespan
• Strong waterproofing performance
• Resistance to weathering and UV exposure
• A neat, professional finish across the full roof area

The Result
The completed flat roof in West Sussex is now fully renewed, structurally improved, and completely watertight.
By stripping the roof back and rebuilding it correctly, we were able to eliminate the hidden defects beneath the old covering and provide the property with a much more reliable and long-lasting roofing system.
The finished result not only improves protection and performance, but also gives the roof a clean, smart and professionally finished appearance.

Why Full Replacement Was Needed
On older flat roofs like this, the visible outer layer often only tells part of the story. Once opened up, it’s common to find:
• Hidden water damage
• Failed insulation
• Timber deterioration
• Weak spots around abutments and edges
In these situations, a full replacement is often the best option to ensure the roof is rebuilt properly and performs as it should for years to come.
