Active Project: Ipplepen Flat Roof Rebuild

We recently executed 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 erected a temporary scaffold roof structure. This controlled environment allowed our technicians to install the 18mm OSB3 decking, warm deck insulation, and multi-layer vapour control systems in perfectly dry conditions.

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 roofing specialists serving the Torbay and South Devon region, Raven Roofing Services strongly recommends a full structural rebuild whenever underlying timber decks or vapour control barriers show signs of rot or water saturation. For property owners across Paignton and Torquay, we exclusively deploy polymer-modified SBS (Styrene-Butadiene-Styrene) bitumen membranes. Unlike standard oxidized roofing felt or fragile GRP fibreglass systems that crack under thermal shock, SBS possesses extreme elasticity and high tensile strength. This allows the roofing envelope to expand and contract smoothly during severe coastal temperature swings without fracturing.

Coastal weather brings torrential driving rain and aggressive salt-laden winds that systematically exploit poorly sealed laps or degraded edging trims. When we strip an old, failing flat roof back to the bare ceiling joists, we do not simply apply a quick patch. We inspect structural falls to ensure positive drainage towards outlets, install new 18mm OSB3 structural decking, and implement rigorous Part L compliant warm deck insulation. This multi-layered approach completely eradicates internal condensation, stops heat loss through extension ceilings, and delivers a robust, warrantied flat roof built to withstand decades of heavy maritime weather.

Whether you are managing a leaking garage roof in Broadsands, upgrading a dormer in Roselands, or constructing a new flat roof extension in Ipplepen, our hands-on trade expertise guarantees an immaculate finish that protects your interior investments permanently.

The Flat Roof Specification

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

Emergency Leak Response

Rapid deployment for active leaks across Torbay. We trace the structural ingress point and provide a definitive, watertight SBS repair to safeguard 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 joists and causes unsightly 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 structural 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 heavy pooling coastal rain without risk of leakage.
