By installing insulation into your flat roof area, J & C's Roofing's team of specialists can help you reduce your home’s energy consumption, helping you to create a more energy efficient home and saving you money on your household bills.

Traditionally, flat roofs consisted of a structural timber deck with a waterproof covering directly applied to the top of the deck. This design dates back many years and insulation was somewhat of an afterthought with this type of roof. This type of roof is known as a ‘cold roof’. Where a cold flat roof does incorporate insulation this is usually in the form of mineral wool, which is placed in between the timber rafters/joists, with a minimum 50mm ventilation gap left clear in between the insulation and the roof deck. This ventilation gap is necessary to allow air-flow, so that warm, moist air is allowed to escape rather than coming in to contact with the 'cold deck' and condensing. Condensation, if not acted upon WILL cause a number of serious problems, including rotting decking and/or timbers, damp ceilings and damp insulation which is rendered ineffective.

Good external ventilation is also essential to minimize the risk of condensation in a cold roof. This should ideally be in the form of 'soffit vents' to the underside of the fascia boards, but, as many flat roofs were built without soffits, is often in the form of unsightly'mushroom vents' on top of the roof.

Good ventilation is essential to allow condensation to escape, particularly where moisture levels are high (such as over bathrooms and kitchens). Unfortunately this means a great deal of heat is also lost in the process.

By moving the insulation to the outside of the structure, the roof deck is effectively brought inside, which results in a 'warm roof deck'. This removes the possibility of condensation forming on the underside of the deck and eliminates damp, because this design works by conserving heat, no ventilation is required.
