The roof is the most important part of the house, as it protects the entire construction from the meteorological conditions. It also regulates temperature transmission, reduces external noise and plays a role in the overall beauty and balance of the construction. A well-built roof improves saves energy, improves the comfort and well-being of inhabitants, and helps to limit operating costs.
The Impact of Meteorological Conditions
The roof is in direct contact with the weather conditions and is subject to natural wear.
Driving rain and the corrosive action of dissolved chemical substances, especially in the presence of crosswinds, favour water infiltration under the roof.
Condensation occurs when an accumulation of steam transforms into water and becomes trapped under the roof structure. This condensation triggers severe corrosion and degradation at a structural level.
Snow and frost can provoke surface abrasions, detachment of roof parts and thermal shock within materials that are not frost resistant, resulting in erosion.
Regular monitoring and maintenance of the roof are essential to ensure longevity and avoid serious issues.
Flexural and compressive strength are used to measure the ability of roofing elements to ensure their stability and resistance to the action of external agents or accidental impact.
Water absorption measures the ability to ensure efficient protection against rain and snow.
Frost resistance measures the level of protection against frost and thermal shock resulting from sudden temperature changes.
Chemical-reactive stability is the ability to withstand aggression from atmospheric agents to prevent corrosion caused by electrochemical reactions.
Always ask for the products' technical data sheets.
A perfect lay ensures stability and resistance to pressure and the atmospheric depression caused by wind.
It also provides efficient waterproofing against rain, snow and ice to ensure rapid and complete water dispersion.
There are those who believe that if you use a waterproof membrane you can install any material on any slope. However, for every type of material there is a minimum slope to be observed. A skilled roofer ensures waterproofing without membrane, which represents an extra barrier to protect the substructure, but is also necessary to fix other kinds of issues such as condensation.
Always ask for product and workmanship warranties \
