The Basics of Roof Installation
Before you proceed with roof installation, it is important to understand the process involved. Here are the key factors that make this process successful. First, the underlayment needs to be installed. Flashing is installed at critical areas of the roof, such as valleys where water from multiple roof planes is directed into a gushing stream. Flashing is a thin layer of sheet metal that protects the vulnerable joints between the underlayment and the roof and directs water away from that area.
During the roof installation process, it is crucial to follow the manufacturer’s guidelines. The guidelines are based on years of experience, research, and thought. Manufacturers take into account different roof types, weather conditions, and the tools used. If you don’t follow these guidelines, your roof installation may be subpar. To protect yourself, take pictures, documents, and other valuables to a safe place away from the work area. You should also relocate any property outside the house if possible.
The next step is the roofing material. The material used for decking is different from that of the rest of the roof. For example, plywood was once the most popular material for decking, but nowadays, oriented strand board (OSB) is the best option for most types of roofs. OSB is made from thin strips of wood held together with a wax or resin compound. The underlayment prevents water from penetrating the roof, which is essential for its proper functioning.
The rafters are cut from framing lumber, and the trusses are prefabricated in factories. They are craned into place. The sheathing is usually plywood or OSB. Older houses may have tongue and groove sheathing boards. The problem areas are the eaves, valleys, and the area where the roof meets walls and plumbing vents. If you want to have your new roof installed, it’s important to have a contractor complete the entire process before you use it.
Next, it is time to nail the shingles. Once you have nailed the felt paper, the next step is to apply the shingles. It should be installed in rows of about four inches, each overlapping the previous row by half inch. Then, you should apply an ice protection underlayment to prevent water from leaking beneath the lower rows of shingles. To apply the ice protection underlayment, first remove the adhesive backing and then apply it in one continuous strip across the length of the roof.
When it comes to installing asphalt, a contractor should be able to make the necessary cuts and measurements. Most common low-slope asphalt roofing materials require professional installation. These include built-up hot-tar systems, which comprise layers of asphalt soaked fabric. The older torch-down versions are being replaced by safer, peel-and-stick modified bitumen sheets. Another option is liquid-applied fiberglass or acrylic, which may not contain an imbedded fabric. These materials also tend to reflect the sun and provide maximum insulation.
After completing the roof removal, it is time to install the new materials. This is an essential step because adding new layers on top of the old ones will compromise the structural integrity of the roof. The process of removing the old roof involves a great deal of danger, so it is important to wear protective gear and watch for falling debris. And if you plan to replace an entire roof, be sure to hire a professional. After all, a new roof isn’t a DIY project – it’s a major undertaking that requires expert knowledge.
