Active Project: Ipplepen Flat Roof Rebuild

We are currently executing a comprehensive flat roof replacement on a timber frame extension in Ipplepen (TQ12). To guarantee a flawless application of the high-performance SBS torch-on system regardless of Devon's unpredictable weather, we have erected a temporary scaffold roof structure. This controlled environment allows our technicians to install the 18mm OSB3 decking, warm deck insulation, and multi-layer vapour control systems in perfectly dry conditions.

While not quite complete, the images below demonstrate the rigorous structural preparation, precise timber upstands, and meticulous edge detailing required for a fully guaranteed, BS 6229:2018 compliant finish.

Emergency Repairs & Structural Rebuilds

Experiencing active water ingress? We provide immediate emergency leak resolution alongside our comprehensive structural flat roof rebuilds.

As dedicated flat roofers serving the Torbay region, Raven Roofing Services recommends a full structural rebuild for systems where the underlying timber deck or vapour barrier has been compromised. For properties in Paignton and Torquay, we strictly utilise polymer-modified SBS membranes. Unlike standard felt, SBS (Styrene-Butadiene-Styrene) offers superior elasticity and thermal stability, allowing the roof to expand and contract during intense Devon coastal weather cycles without cracking.

Every project managed by our senior technical team includes a rigorous inspection of structural falls and the implementation of Part L compliant insulation to prevent internal condensation and heat loss.

The Flat Roof Specification

Proper trade standards require a multi-layer approach to vapour management, thermal retention, and waterproofing.

Emergency Leak Response

Rapid deployment for active leaks in Torbay. We trace the structural ingress point and provide a definitive, watertight SBS repair to protect your interior assets.

3-Layer Bonded SBS

We utilise high-performance SBS torch-on membranes. This includes a perforated venting layer, a 2mm reinforced underlay, and a 4mm mineral-surfaced cap sheet for ultimate UV protection.

Warm Deck Upgrade

Essential for extension comfort. We install rigid PIR insulation boards above the structural deck, moving the dew point outside the building to eliminate internal dampness.

Skylight Integration

Expert installation of Velux flat roof windows and technical skylights. We prioritise proper kerb upstands and high-performance flashing to ensure apertures remain watertight.

OSB3 Deck Replacement

Structural integrity begins with the base. We replace perished timber with 18mm OSB3 structural decking, ensuring a level and secure foundation for the new SBS system.

Vapour Control Management

Applying a high-bond vapour control layer (VCL) is a critical step many skip. This prevents internal moisture from being driven into the insulation and structural timbers.

Technical Insights: Flat Roof Rebuilds

Why is Warm Deck roofing essential for Torbay homes?

In coastal districts like Paignton (TQ3/TQ4), the temperature difference between internal heating and external cold air often causes a "dew point" on the underside of a roof deck. A Warm Deck rebuild moves this dew point above the structural rafters, effectively preventing interstitial condensation that rots timber rafters and causes damp ceilings.

Should I add a Velux during a structural rebuild?

Yes. The optimal time to install a Velux flat roof window or skylight is during a rebuild. This allows us to construct the mandatory technical upstand (kerb) and integrate the 3-layer SBS system directly into the window frame for a 100% watertight seal that handles pooling coastal rain.
