Single-ply roofing has been used since the late 1970s for many buildings in the UK, including airports, hospitals, schools, supermarkets, and even sports stadiums. In recent years, it has also become a popular roofing choice for housing.
Single-ply roofing is made from flexible and resilient membranes. It is durable and is a complete roofing solution that will keep heat in while keeping wind and rain out.
There are three basic types of single-ply roofing systems:
- Warm Deck
A warm deck system has a single-ply membrane laid over a base layer of thermal insulation. The insulation sits on top of a vapour control layer (VCL). This system is effective at keeping the roof decking warm during cold weather, reducing condensation, and preventing water vapour from getting into the insulation.
- Inverted Warm Deck
The inverted warm deck system is similar to warm deck, except that it further protects the single-ply roofing with unique weather-resistant insulation placed above each layer and held in place with stones or paving.
- Cold Deck
The cold deck system is traditional and cost-effective for flat roofing. It involves placing the waterproof membrane directly onto the roof decking. Insulation is then laid under the deck.
