Roof Construction - How Is It Built?
Are you curious about how the roofers constructed their homes? Are you aware of the various materials? There are several types of roofing materials like made-up roofing, plywood and OSB. In this article, we'll look at what each one of them does and how they fit together to form the roof. We'll then look at Sheathing, Roof trusses and Roof trusses. We hope you'll be able to appreciate the importance of these products for your home's roof by the close of the course.
Sheets of roof tiles that are built-up
Built-up roofing ply sheets are comprised of special layers of fabric. They are laid on top of hot or cold bitumen. Ply sheets are usually strengthened with fiberglass or other organic materials. They also create a stronger roof layer. These roof layers also keep out the elements, and are strong enough to be suitable for commercial structures. The standard width for plywood sheets is 36 inches.
Sheathing
Sheathing is the fabric which holds the roof in place and gives it its strength and endurance. The roofing professionals utilize sheathing to stop a home from sliding and ensure that the roof has the ideal design. Inspecting the attic is best way to find out if there is any sheathing missing. If the roofline appears to be wavy, it's likely that the sheathing has been damaged. The roof may have a weaker sheathing if you feel the wood give way.
Roof Trusses
Traditionally, roofers have constructed roofs with rafters made of 2x8 or 2x10 wood. The roof is attached to the exterior walls via the rafters. They are used to support the weight of the roof and are joined by roof boards that are fixed to the rafter boards. Rafter boards are generally covered with insulation or another material , and then fastened to the faces of the trusses. If the trusses are of greater width than beams that are ridged, the rafter boards can be replaced by ridge beams.
Roof that covers
Felt underlayment has been used by roofers for many years and is still the most popular choice. It's inexpensive and simple to install, but is not completely waterproof. The majority of roofing contractors utilize 15-pound felt. Thicker 30 pounds felt is stronger and more resistant to damage. Felt is gradually being eliminated by roofers due to its ineffective waterproofing capabilities. However, it will work for some roofing applications such as flat roofs.
Metal roofing
Metal roofs are created out of metal coils that are long continuous rolls of metal. They are coated and treated. The steel is then divided into panels that are similar to the shapes of different types of roofing materials. The panels are then joined to form an roof. Roofers should be acquainted of the terms "tin roof" and "steel roof" as these do not refer to metal roofing. However, if you are contemplating installing a metal roof on your home there are some points to be aware of.
Roofs made of wood
A roof made of wood can last for several years, depending on the wood species it's made of. However, it is possible to see deterioration in the event that the shingles are thin. Other elements that can cause a roof's decline are exposure to rainfall, the kind of shingles used, as well as the slope of the roof. The effects of rainwater, grit UV rays, grit, and wind all influence the wood shingles.
Trusses Prefabricated
Roofers used to construct trusses out of large lumber. They then assembled them on site. It was a lengthy and labor-intensive job which could take one week. Roofers don't have to worry any more with the clutter. Pre-fabricated trusses can be completed in one day. Because the trusses are able to cover greater distances without interior walls they are also able to construct any kind of roof.
