usually the lowest part of one or more pitches of the roof is identified as the gutter, ie where all the rainwater falling on the roof is channeled.
The eaves, almost always also called "gutter channel", must be sized according to various parameters such as: the area of the roof, the number and diameter of the drains, the number of angles, the risk coefficient, etc ... for do not risk harmful overflows outside or even inside the building.
The "channel" can be made in many ways starting from the materials: in press-folded metal laminates rather than in PVC or bituminous sheaths, or with "head-to-head" expansion joints rather than joints in vulcanized plastic material.
usually the highest part of one or more aquifers is identified as the ridge, ie where the rainwater begins its run-off path towards the eaves.
If not carefully studied, harmful infiltrations may occur inside the building.
roof element designed to retain snow on the roof preventing it from falling into the underlying areas, creating serious damage to people and things.
It too must be suitably sized and calculated its layout on the roof based, for example, on the slope of the pitch, the materials of which the roof is composed and above all the area and height above sea level in which the roof is located in order to understand the snow load to be to apply.
very important on a roof as on all other types of cladding and mounting (facades, false ceilings, curtain walls, skylights, systems, etc.) are the fixings that ensure perfect coupling of the panels with the load-bearing structure.
The fixings must be chosen on the basis of the support on which it is decided to anchor (wood, steel, concrete, etc ...), on the basis of the working conditions (more or less corrosive, choosing suitable materials or treatments) and suitably sized according to to the various loads present such as wind thrust, wind extraction, snow load, etc...
Set of fall arrest systems, usually placed on sloping roofs, designed to ensure the safe work of operators who have to perform ordinary or extraordinary maintenance work on the roofs in question.
