All roofs have a finite life and sooner or later the cost of continually patching up an old roof will overtake that of complete re-roofing. Moreover many older properties were constructed without proper underlay or insulation. A new roof enables the installation of these energy saving items as well as installing roof space ventilation to meet modern standards.
When re-roofing or extending an old roof, the key is to replace or match "like with like".
Insulation within the roof covering industry has recently become a major factor when considering any new or refurbishment works.
Careful consideration should be given to possible condensation problems when insulation is added to the roof design, as this can become a major – and expensive – problem if not dealt with correctly prior to installation!
There are basically two types of roof construction: “warm roof”, where the insulation is fitted to the outer surface of the rafters; and “cold roof”, where the insulation is fitted between the rafters or at ceiling level.
Recently the Warm Roof method has been the preferred method of construction as this does not require ventilation above the insulation, the provision of which, in many circumstances, can become very expensive.
Cold roofs must always allow for the free flow of air to pass above the insulation to allow for condensation to be dissipated to the outside of the structure.
All “cold” roofs must be fitted with adequate ventilation, whether it be at eaves, ridge, valley or hip. Some tile and slate manufacturers provide purpose-made products to fit their own products, whilst other manufacturers provide universal products to meet a wide variety of standard applications, common to many types of coverings.
