The roof is one of the most important elements of a house, perhaps the element that represents living more than any other. The roof, in fact, has the fundamental function of shelter from the elements, and more. If the roof shows cracks and fissures, it could be dangerous for the entire structure and the stability of the building itself. One should never underestimate problems of this type,
The Functions of a Roof
Before discussing the interventions to be undertaken to renovate a roof, it’s important to clarify more specifically what its main functions are:
1) Protect from the elements
2) Insulate the building, significantly limiting heat dispersion
3) Waterproof it, reducing infiltrations, preventing mold formation and material degradation
4) Ventilate, dissipating heat that accumulates under the tiles, keeping the environment dry and promoting controlled snow melting.
Roof Repair Interventions
Having framed the functions of a roof, we can list the necessary operations to undertake the renovation of this specific part of a building:
1. Dismantle the old roof
Before starting the operations of rebuilding a new roof it is essential to remove the old covering, first removing tiles and shingles, then the underlying materials. The operation must be carried out with extreme care: the roof corresponds, in fact, to various pipes and drainage channels, as well as beams, coverings, and walls.
2. Waterproof the new structure
Waterproofing the roof is a necessary practice. This operation will prevent water from flowing from the roof surface to the underlying layers of the structure. Before proceeding, however, it will be necessary to carefully check for depressions and slopes. Additionally, it will be necessary to verify the condition of the supports and surfaces on which work will be done.
3. Insulate
Insulation is a fundamental practice for thermally insulating the building. A well-insulated roof is a fundamental ally against sudden temperature changes. With an insulated roof, in summer, heat will penetrate less into the structure, while in winter, conversely, heat will not be dispersed. This allows for great savings from the point of view of air conditioning and energy used more generally. To insulate a roof, panels made of wood fiber, rock wool, polystyrene, or cork are used. These panels are installed both on the outside and inside of the roof and also in the attic.
4. Create a ventilation layer
To have a well-ventilated roof, it is necessary to create a gap between the covering elements and the underlying layer. Good ventilation will allow domestic water vapor to be eliminated through the roof. This is necessary to prevent the formation of condensation and mold.
Consider Installing Solar Panels
As already seen, roof renovation is a fundamental element for improving the energy efficiency of a structure. If you want to proceed with further energy efficiency of the building, you can also consider installing solar panels. Renovating a roof can be the ideal opportunity to install them. However, some houses, especially those located in the historic centers of cities, cannot install solar panels on the roof due to landscape constraints. It is therefore advisable to consult a specialist technician in advance, evaluating all possible solutions for the installation of a photovoltaic system.
The “Roof Bonuses” for 2023: Never Compromise on Renovation Quality
Roof renovation is a relatively complex practice, consequently the costs for its renovation are often considerable. However,
It’s important to specify that there is no specific bonus for roof renovation, but roof renovation interventions can be included in other tax bonuses such as:
- The Superbonus: in 2023 this tax deduction goes from 110% to 90%. To obtain it, it will be necessary to carry out:
a) Thermal insulation interventions on 25% of the opaque horizontal, vertical, and inclined surfaces of the building, which delimit the heated volume. Roof insulation works fall into this category.
b) Renovation works that involve improving the building’s energy efficiency by at least 2 energy classes.
- Ecobonus 65%: for energy requalification works on single dwellings and condominiums, up to 65% tax deduction can be requested.
- Sismabonus: this incentive has also been extended. It is intended for those who want to carry out construction works to prevent the risk of collapses and damage related to a seismic event. Roof renovation works, if actually based on anti-seismic criteria, can also fall into this category. The tax deduction will vary depending on the interventions carried out.
- Renovation Bonus 50%: this incentive includes all ordinary and extraordinary maintenance works of a building. It will be possible to deduct 50% of the expense incurred from IRPEF in ten annual installments.
