Roof renovation or loft conversion?
Are you just planning to re-cover the roof? As part of a roof renovation, the insulation should also be brought up to date and possible use of the attic should be considered. Because roof windows, dormers, or bay windows can be easily integrated when craftsmen are already busy re-roofing the roof. It can also be worthwhile to combine upcoming work with other measures. For example, replacing the thermal insulation can make sense for an energy-saving renovation. This way you reduce your energy consumption and save on heating costs. This can be very efficient, especially when renovating the roof of an old building.
What is a roof renovation?
Roof renovation involves replacing the roof cladding by Empire Construction and, if necessary, the entire roof structure, combined with the installation of new thermal insulation. The complete conversion of the attic into a new attic apartment is usually considered roof renovation work.
Why is a roof renovation worth it?
If you insulate your system correctly, you will first reduce your energy consumption and therefore save expensive heating costs. This also contributes to a healthier indoor climate. In addition, you can create new living space with a complete loft conversion.
When does a roof renovation make sense?
A roof renovation makes sense at the latest when the roof is leaking, can no longer protect your house from the weather and moisture gets into the roof structure. Even if you notice that the heat generated is no longer staying in the house, Roof Repair Contractors NYC recommends renovating the roof and replacing the insulation.
Check structural requirements (EnEV) beforehand
If you decide to renovate your roof and expand and use the attic or loft for new residential purposes, you should also consider the requirements of the EnEV (Energy Saving Ordinance). But even without an extension, the top floor, in most cases the floor of the attic, must be insulated accordingly to meet the legal requirements. There are different options for insulating the roof depending on the requirements.
Roof insulation – these options are available
Depending on the extent of the roof renovation, different types of roof insulation are available.
Rafter insulation
Rafter insulation is primarily used when the roof is being re-roofed. The insulation is installed completely on the roof beams, with vapor barrier film and insulation material completely covering the roof surface.
Between rafter insulation
With intermediate rafter insulation, the roof is insulated from the inside. The insulation material is clamped between the rafters. The roof does not have to be covered, but cutting the insulation precisely requires more work.
Under-rafter insulation
If, for structural reasons, insulation between the rafters is not possible with sufficient thickness to achieve the desired insulation value, insulation under the rafters is also possible by Local Law 11 Contractor NY. An additional layer of insulation is placed under the rafters.
