Warm Deck Flat Roofing Paignton
Upgrade your Torbay property with high-performance PIR insulation and Torch-On Felt systems for total thermal efficiency.
What is a Warm Deck Roof?
A Warm Deck Roof is a modern flat roofing system where the insulation (typically 120mm PIR board) is installed above the structural deck. This creates a continuous thermal blanket that keeps the roof structure at the same temperature as the interior, effectively eliminating condensation and meeting Building Regulations Part L. Raven Roofing Services specialises in these systems across Paignton, Torquay, and Brixham.
Why choose a Warm Deck system in Torbay?
For homeowners in Preston, Goodrington, and Roundham, older flat roofs often suffer from "cold deck" issues—where damp air hits the cold timber, causing rot. A warm deck system from Raven Roofing Services solves this permanently and makes your home much more comfortable.
- Brilliant Energy Savings: Drastically reduces heat loss through the roof.
- Total Moisture Control: Moves the dew point outside the building.
- Enhanced Longevity: Protects your timber joists from thermal shock and rot.
- Full Compliance: The most reliable way to meet modern U-value requirements.

Myth vs. Reality: Modern Flat Roofing
Myth: "Flat roofs always leak"
Reality: Modern High-Performance Torch-On Felt systems are multi-layered and cross-bonded, creating a seamless waterproof membrane that is incredibly durable and built to last.
Myth: "Extensions are always cold"
Reality: A 120mm Warm Deck installation transforms an extension into the warmest room in the house by trapping heat before it ever reaches the ceiling joists.
Warm Deck FAQ for Paignton Residents
A standard compliant installation adds approximately 130mm to 150mm to the total roof height (this includes the insulation, new deck, and the felt layers). At Raven Roofing Services, we always carefully check door thresholds and window sill heights in Paignton properties before we start, ensuring a perfect and practical fit for your home.
If your current deck is damp or sagging, we always recommend a full replacement with 18mm OSB3 structural boards to ensure a solid foundation. For a warm deck, we then install a vapour control layer directly onto the deck to protect the PIR insulation from any internal moisture rising through the house.
Both are great options, but Torch-On Felt remains a favourite for warm decks because of its superior flexibility during thermal expansion. This is really important in the variable coastal climate we have here in Torbay, as it allows the roof to breathe and move without cracking.
