The shelter is an important part of a sloping roof and determines its watertightness. It performs various functions. Today we distinguish three types of roofs: membranes, flexible panels and rigid panels.
The shelter is an important part of a sloping roof and determines its watertightness. It performs various functions. The most important thing: accidentally catching water, for example after a roof tile has been blown off or broken during stormy weather or after powder snow has blown in. It also makes a construction temporarily watertight as long as the final roof covering has not been installed. In cold weather, the shelter removes the condensation that forms at the bottom of the roof covering. It also protects the attic space against dust and directs water vapor from the inside to the outside. A shelter must therefore be vapor-permeable. Plastic roofing films, even those with micro-perforations (such as those used on a large scale in the 1970s and which are the cause of many roof damage), are therefore not suitable.
Membranes
Membranes based on synthetic materials are reinforced with synthetic fibers. They are waterproof and vapor-permeable. Advantages: easy and quick to install and affordable. A disadvantage is that the membrane can be pressed against the underside of the roof covering during the placement of the insulation.
Flexible panels
The synthetic panels, consisting of layers with an alveolar structure that have been perforated, are cheaper than the panels in fiber cement but do not guarantee the same quality. Fiber cement panels are made on the basis of a homogeneous cement mix, natural and synthetic fibers and mineral additives. They are vapor-permeable, waterproof and insensitive to mold. The cost price is considerably higher than that of membranes, which can be a disadvantage.
Rigid panels
These panels are made on the basis of sawing waste and wood fibers. They are waterproof and moisture-regulating. They cannot only act as a shelter: rigid panels can be 70 to 80 mm thick and provide additional insulation for the roof. Moreover, they offer (limited) protection against overheating. Because they form a thermal break at the level of the rafters, they also prevent construction nodes. A disadvantage is that the cost price is considerably higher than that of other shelter materials. They also make the roof thicker.
Air Conditioning Repair and Installation
Having the proper heating and cooling system installed is important for your comfort and for your energy bills. Contacting and using a qualified HVAC contractor for air conditioning installation is critical, as the wrong set up can cost you way more on your energy bill and may not cool your home or office properly.
