Money is of a great value to anyone or everyone! Thus it is necessary to take into consideration the cost of insulating the flat roof. A choice where value for money goes hand in hand with the quality of insulation should be made. Mainly, the installation companies will provide with the calculations as soon as they quote for a new roof. There maybe cases where the insulation material might be suggested to be reused by the installation company taking into consideration its current condition.
The detailed breakdown of the cost of the insulation material is presented by the professional firms along with the quote sheet in order to provide you with a better picture of the cost.
The actual cost of the insulating the roof depends numerous number of options such as minerals (rock and glass wool), synthetic materials (expanded or extruded polystyrene, polyurethane, etc.) or natural (wood wool, hemp, cellulose, etc.).
In addition to above there is always some extra work required whether insulating from inside or outside:
interior finishing: plastering, installation of the panels, painting, upholstering, repairs or changes to be made to the electrical circuits.
outside roofing: removal and installation of tiles, replacement of battens, installation or replacement of the lining membrane. The roof that is insulated from the outside is called “sarking roof”. This where the bare roof construction is covered with the insulation material. In order to protect the insulation material against the wind and rain it is important to install foil. The benefit of insulating the outside roofing is that there maybe some places in the building where the insulation material may be disrupted, due to which the heat may escape out.
Inside roofing: during the insulation of the inside roofing the roofing and roof construction remain as it is. The cost for insulating from inside is lower than the insulation of the outside roof as inside insulation is not as drastic as the outside. Plasterboards are used in order to finish the sloping insulated wall. In the end the craftsmen might provide a finishing layer for the insulation materials. The main advantage of insulating the roof from inside is that many of the damp problems can be avoided. This is possible as a vapor barrier is installed with the insulated material to prevent condensation and molding.
The property owner has the option of choosing from whether using insulation wool or insulation boards. Pitched roofs are mostly insulated with using insulation wool shaped as blankets. This is easy to compress and cut into different sizes.
On the other hand, insulation boards are hard in nature and light in weight. These can be used to insulate any kind of roofs and are also easily cut into different sizes. Insulating using boards will enable one to even walk on them in case of insulating the attic floor.
