Roofing is one of the most important factors during building and home development process as it is imperative to provide some sort of shelter to every structure. Not surprisingly, the options for roofs have modified during the historical period especially in the last couple of decades. As the construction increases, the number of such options that become available also increases. These options are not only fulfilling the sheltering requirements but also improve the aesthetical appearance of the structures. Below are provided the various choices that are now available to owners.
Built up roofs
One of the most classical options that continue to remain popular is the built-up roof. Developed over a hundred years ago, this kind of roof is time tested and often the default choice with a large number of homeowners. However, this is not the perfect roofing choice and poses several limitations. This roof is appropriate for high-traffic locations with high possibilities of mechanical abuse to the roofs. Compared to other available options, the built-up roof is stronger and thicker with multiple layers and gravel surfacing. However, the biggest limitation of this kind of roof is its inflexibility. The built-in roof is susceptible to damage due to thermal or structural movement. Plenty of care and maintenance is required in places that have extreme climatic conditions.
Modified bitumen roofs
These kinds of roofing solutions have the same limitations and benefits as those with the built-in roof. However, this type of roof performs significantly better in cold climates because these are designed to include flexibility when the temperature drops. This makes the modified bitumen roof better adaptable to climatic modifications than the built-in roofs. These are classified as rubber-based and plastic-based roofs. Rubber-based membrane installation is done using hot asphalt or cold adhesives. The plastic membranes are installed using torches. The modified bitumen roofs have granulated surfaces making these lighter than built-in roofs.
Single ply roofs
As suggested by the name, this kind of roof is made with a single layer of elastic or plastic material. Because it comes with only one layer, these roofs are thicker. Single ply roofs are of two kinds; thermostat membranes where seams are sealed with adhesives and thermoplastic membranes where the seams are welded with a solvent or heat. These roofs have three attachment options, fully adhered, ballasted, and loose-laid. Because these are inexpensive and light weight, single ply roofs are used for re-covering.
Metal roofing solutions are no longer limited to sliding panels that are not secured properly and nailed to the frames. Currently, many choices are available with secured clips that are expandable and contractible. The most important benefit of choosing metal roofs is the durability and longevity. These last for many years even when exposed to extreme climate conditions with some warranties available for as long as fifty years. One major disadvantage of metal roofs is the possibility of leaks when compared to most other kinds of roofing solutions. However, when installed properly, the possibility of such leakages reduce significantly eliminating this disadvantage of this kind of roofs.
