Why choose single-ply roofing?
Single-ply roofing has been used since the late 1970s for many buildings in the UK: airports, hospitals, schools, supermarkets, and even sports stadiums. In recent years, it's also become a popular roofing choice for housing.
Single-ply roofing is made from flexible and resilient membranes. It's durable and it's 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.
