There are many roofing materials to choose from, but what are the advantages and disadvantages of each and how durable are they? Lance
At Revue New 132 we look at the options available for walls when building or expanding. But really, the house has more than just the walls: the roof is just as important, as it not only protects the rest of the building, but also counteracts the extreme levels of solar radiation from any part of the house. Should be done. Also strong winds, rain, and hail. Check more at details at Ottawa Roofing.
In addition to supporting additional structures such as solar panels and solar hot water systems, satellite dishes, ventilation and air conditioning systems in the roof, people also have to bear the weight while installing and maintaining such systems. Also, it is used to collect rainwater for your home and garden.
There are many roofing materials available, including corrugated iron and corrugated steel, concrete, ceramic, metal and composite tiles, slate, shingles, and even load-bearing panels such as SIP (structurally). Conductor panel). Each option has its advantages and disadvantages, each has its own specific shape and each comes within a range of options for that particular content.
The type of roof you choose depends on the material and general appearance of the rest of the house, as well as your personal preferences, which can be determined by a number of factors, including appearance. Includes material environmental certificates, its limits. Colors and styles are available, construction methods (some roofing materials require more structural support than others), the level of care you are willing to give the roof, the level of fire resistance required and The required location and therefore the surrounding environment of the house, including the heritage or aesthetic requirements of your town hall. Let's look at each item in return.
Sheet Materials
Galvanized Iron / Color Bond Steel
These materials are manufactured from a thin sheet of steel (usually less than 1 mm thick) and painted on top of a coating of zinc (galvanized iron), an aluminum / zinc / magnesium alloy (zinclum), or zinc alloy. Are coated with. (Color Bond) There is also a stainless steel version of Color Bond for extreme coastal environments.
Sheet steel materials come in a wide range of profiles (shape, corrugated or otherwise when viewed), including common corrugated iron, mini versions (such as Lesgit mini arb, which is commonly used in walls but Can be used as roofing material), as well as profiles that are more commonly used for commercial roofs but are also suitable for some home projects such as trimmed, clip lock and many others. Visit www.steelselect.com for information on the types of profiles available.
This is how all sheet steel products are used: they are pulled on wooden or steel planks (or sometimes nailed) or fastened to the printed brackets that are stuck to the slates. Either way the edges of the sheets are overlapped to prevent water from entering, but concealed fasteners remove the roughness of the sheets attached with screws or nails and provide a more reliable weather seal. The various gutter designs come complete to provide a clean and tidy supply to the knives.
Another technique that uses sheet roofing is the "raised seam" method. Sheet metal "trays" are made of flat sheets with vertical edge layers that are joined together and then joined together in the form of a crimp groove to complete the seam. It allows the use of very long tray panels (10 meters long) and is suitable for large ceilings and roofs with lave fitting or convex curves. The downside of the system is that once the panel is locked, it becomes harder to separate than sheets that only have bolts on.
The advantages of sheet steel products are considerable. They are light weight and relatively easy to handle (although care must be taken on windy days), they are easy to carry and quick to install (for professionals, at least), they are very strong , And if installed they will remain. Decades with minimal care. They are also extremely fire resistant, although heat and sound travel easily through sheet steel products.
Sheet products have very few defects, but improperly installed sheets can be a serious hazard when cleaning gutters when gutters have a long distance to cover.
Many sheet steel products contain recycled steel (see the data sheet for recycled materials and other durability properties as it varies between products and manufacturers), and all sheet steel easily recycling systems. These products are easily recycled, so there is no reason for these products to run out. Join Landfills at the end of your useful life.
Conductor / SIP panel
They consist of two sheets, usually coated or painted metal, such as color bond sheets, which are formed on each part of a layer of insulated foam. They are like structural insulation panels (SIP). Indeed, SIPs can be used as roofs, but roof panels such as Riteish Custom Roof Panels, Stratco's Coldak Range Insulated Panels, and Versacelad are specifically designed for roof applications.
They are very strong, light weight and easy to install, and can provide a home with first degree thermal and acoustic insulation. This type of panel is available in thicknesses of 125 mm or more, so the insulation level may be sufficient. If you look around you will find R2 to R5 or higher around home grade SIPs.
Maintenance requirements are minimal, just like ordinary sheet products.
Syllabus
Tile has been a popular choice in Australia and many homeowners prefer the final result. All tiles, regardless of the material from which they are made, have the advantage that they can be easily replaced if damaged, such as falling tree branches, being stoned, and so on. Unlike sheeting, only the damaged area needs to be replaced, not the entire roof from the lid to the gutter. Today, a lot of materials are used for tiles, so let's look at the most common things.
Concrete tiles
Not surprisingly, concrete tiles are made of cast / pressed concrete, a mixture of cement, sand and varnish. They are available in a wide range of colors and patterns, including traditional style, slate flat tiles, beveled and textured tiles.
Concrete tiles are relatively brittle because they usually do not have internal reinforcement such as structural concrete. If they run on them after being installed incorrectly, they break very easily (a common problem after working on the roof, such as having roofing equipment) or dropped during installation, or If they are affected by falling trees. Branches and the like.
Concrete tiles can live up to 50 years or more, and if care is taken when preparing a home, concrete tiles can find a second life in another construction project. Older tiles can also be shrouded and recycled as filler material in new concrete or for other construction sites.
One aspect of concrete prices is that they are heavier, so concrete has relatively less embodied energy per kilogram than other roofing materials (see your home's embedded energy page), sheets and similar products. In competition the result is recovered which is more covered per unit. Enough embodied energy for a typical roof.
In addition, this massive scale means that the roof structure should be able to support the weight of several tons of tiles during the life of the building. Because these skins are relatively small, roofing panels also need to be kept close enough, resulting in more use of materials for the roof structure and more time to install than sheet products.
Acoustically, at least two manufacturers reported that their brightness would reduce external noise through the roof to 30 dB, which is considerable, so if there is a noise problem, roofs are good candidates for rod materials. ۔
