There are several best practices for new roof installation. Some of the important areas to consider are the use of corrosion-resistant nails, thermal expansion of light-gauge metal panels, and creating a contract. Read on for additional information on how to avoid trouble spots and improve your roofing installation technique. Moreover, you should never try to install a new roof on your own; always hire a professional roofing contractor.
Avoiding thermal expansion in light-gauge metal panels
When installing a new roof, consider the potential for oil canning, or small deformation and buckling. This phenomenon occurs more often with light-gauge metal panels than with heavier gauges. It can occur during all stages of the process, including panel creation, handling, and storage. In addition to oil canning, it can result in excessive tension and oil cans, which are both potential roofing problems.
The problem with the thermal movement is that it’s invisible to the naked eye. Even roofing contractors are unlikely to notice the quarter-inch expansion or contraction in an aluminum panel. Typical failures are gradual and occur over many seasons and dozens of thermal cycles. Sometimes the failure of an installation is because of poor workmanship because the building owner or original installers were not there.
Installation Instructions
Roofing contractors should follow the manufacturer’s installation instructions when installing light-gauge metal panels. During installation, they must install perpendicular to supports and within tolerances for thermal movement. It is important to follow the manufacturer’s instructions regarding the purging and sealing of panels. Roofing professionals should only work with actual equipment to install the metal panels. Metal panels should install correctly.
When installing a new roof, professionals must follow the manufacturer’s instructions for crimping exposed flashing, ensuring the seams are flat and have no buckling. Using mechanical seamers is important, but caution should exercise when seaming panels on slopes of six to twelve percent, as slippage will cause finish scratches. The only approved equipment for such seaming is available from D.I. Roof Seamers.
Using Corrosion-Resistant Nails
The use of corrosion-resistant nails for a new roof construction is critical for ensuring the long-term durability of your new structure. The main reason for corrosion-resistant nails is the fact that they are resistant to the elements. This is because corrosion is a chemical reaction between steel and oxygen in the air. In the course of oxidation-reduction, the metals give up electrons and turn into iron oxide solids. In addition, salty air speeds up this process.
The proper choice of nails for a new roof installation depends on the materials used for the structure. Galvanized nails are not good for use in the roofing material. Instead, use corrosion-resistant nails. While aluminum nails are relatively inexpensive, they are durable and have a hard finish similar to steel. In addition to being inexpensive, aluminum nails have the ability to simulate steel’s properties.
Advantage of Corrosion Resistant Nails
Stainless steel roofing nails are made from alloy steel and nickel and are suitable for wood shingles. Stainless steel roofing nails are the most corrosion-resistant and are usually available in various grain sizes. You should choose nails with a minimum 3/8-inch diameter head and a length of 3/4 inches. For an optimal new roof installation, make sure that the nails are long enough to penetrate through the roof deck and extend 1/8 inches beyond the lower side. During the installation process, consider the number of layers of shingles, the thickness of each layer, the underlayment, and the flashing before choosing the proper roofing nails.
Another advantage of corrosion-resistant nails is that they are easier to remove than other types of nails. For example, you can use stainless steel nails to repair any faulty nails. You will also be able to reuse the same nails for a new roof installation. Stainless steel nails are ideal for areas that experience high levels of salt exposure. This means that if the nails are corroded, the shingles will be vulnerable to water.
Moreover, using corrosion-resistant nails will reduce the risk of your new roof rusting. The zinc coating of these nails will get worn out over time. Therefore, it is smarter to purchase new nails to avoid any rust issues. During the process of building a new roof, corrosion-resistant nails are recommended. If the old nails have already corroded, you’ll need to replace them.
Creating a contract
Creating a contract for a new roofing installation is a great way to protect yourself against miscellaneous charges. This contract template has been designed by roofing experts, and it includes pre-existing content. You can modify it to meet your specific needs, then download it and edit it using your favorite software application. A sample contract can be downloaded to your computer or portable device and customized to suit your needs.
You should also create a standard roofing contract, which includes blanks for variables like pricing and payment schedules. A standard contract is much more stable than a customized sales proposal, which will often be outdated due to changes in legislation and worker safety policies. Update your contract at least quarterly or semi-annually to reflect any changes. Be sure to include your company name, and license number, as well as the date and location of the new roof installation.
A standard roofing contract should detail all the materials and services included in the scope of the project. It should include basic roofing materials, and labor, as well as any applicable permit fees and cleanup and disposal services. Similarly, the contract should outline specific products and their manufacturer’s warranties. A standard contract will include these items and the costs they incur. In case of disputes, there are specialized legal documents that can protect you and your property.
Checking to flash
When you have a new roof installed, you don’t always replace the flashing. You may need to replace the flashing if there are leaks, or if you’ve noticed that your old flashing has rusted or has holes in it. These problems are easily fixed if you know how to look for them. You should also inspect your roof for leaks. If you notice any of these problems, you should immediately contact a professional roofer to fix the problem.
The first step in checking the flashing on your new roof installation is to check the height and type of materials used for the flashing. You should be able to find the proper height and use binoculars to inspect the flashing from a window. Next, you will need to make sure that you have a sturdy ladder and that it is long enough to reach the roof. If your roof is steep, don’t attempt to check the flashing yourself. A professional roofer can do it for you.
Another way to check the quality of your flashing is to check the location where it’s installed. Poorly installed flashing can lead to leaks at the corners of your roofing. Those leaks may be difficult to identify without a professional inspection, but a good roofer will know how to spot these problems and provide quick fixes. If your roof is too old, you should consider hiring a professional roofer. If you’re a DIYer, you can try to crawl up into the attic to check if there are any loose flashing or missing nails.
Properly installed flashing protects the interior portion of your home. Flashing prevents water from seeping behind your shingles. Without proper protection, water can penetrate into your home, damaging the interior walls, ceilings, insulation, and electrical wiring. Properly installed flashing will prevent these leaks and ensure your roof is protected for many years to come. If you’re considering a new roof installation, be sure to get the job done right.
