A cover roof is a type of roof renovation method.
Roof renovation methods differ greatly depending on the type of roofing material, and can be broadly classified into the renewal method, in which everything related to the old roof is removed and a completely new roof is installed, and the cover roof method, in which the old roof is left in place and a new roof is installed over it.
Unlike the renewal method, the cover roof method does not require the removal and disposal of the original roof, thus reducing renovation costs.
Another major advantage is that there is no need to worry about asbestos.
The cover roof method is used to renovate the roof of a building.
The target buildings are general housing, but it can also be applied to the remodeling of roofs on buildings such as factories and stores.
In both cases, remodeling is performed by covering the existing roof with a new roof.
In the case of residential buildings, the new roofing material can be lined with insulation or soundproofing material, and functional renovations such as adding roof ventilation to prevent moisture are also possible.
One example of cover roofs method is to cover the top of an old slate roof with galvalume steel, a lightweight metal sheet.
Compared to the renewal method, which completely replaces the slate roof, this method does not require dismantling and disposal of the old slate.
Therefore, the cost of construction can be reduced and the construction work is simpler compared to the renewal method, so the renovation can be completed in a short period of time.
Even in the case of stores and factories, the cover roofs construction method can be performed while the facility is still in operation.
The new layer of air between the existing roof and the new roof provides thermal insulation inside the facility, making it possible to lower the temperature inside the facility in the summer and, conversely, raise the temperature in the winter.
Furthermore, some of the latest cover roofs construction methods boast high strength and long life.
