Installers need to correct several things when erecting an asphalt shingle roof. These mistakes can occur because of improper installation, tools, or fasteners. In addition, these mistakes can lead to costly mistakes down the road. Learn how to avoid these mistakes, as well as how to prevent leaks from forming.
Common mistakes made by asphalt shingle roof installers
Whether you have a flat or curved roof, the first step is to measure your roof carefully. This will avoid causing extra costs and delays. In addition, the correct measurements will avoid gaps that can let water in. A roofing calculator is a great tool to help you measure your roof correctly. If you need more confidence in your skills, you can call an asphalt shingle roofing contractor to complete the project on your behalf.
Installing an asphalt shingle roof is a complex process. Improper installation can affect its longevity, performance, and quality. A professional roofer can ensure proper lapped panels and sealed seams. If not, leaks can occur, and the entire structure may fall apart. The last thing you want is a roof to blow off in heavy windstorms. So, it’s critical to hire an asphalt shingle roof installer with expertise in roofing.
Asphalt shingle roof installers should follow a few basic procedures to ensure a proper installation. For example, they should measure the length of the roof and its slope. Inexperienced contractors often need proper measurements to do this step and cut panels. This can result in jagged edges and an improperly-sized roof panel.
Another standard mistake asphalt shingle roof installers make is failing to use the proper underlayment. The incorrect underlayment can create a wavy effect on the asphalt shingle roof, resulting in a corrugated appearance. The correct underlayment is essential for protecting asphalt shingle roofing against moisture. Inexperienced asphalt shingle roof installers may need to learn the difference between the two types of underlayment, which can result in problems later.
When installing asphalt shingle roofing, it is essential to use standard screws. While the installation process may seem simple, many problems can result from improper installation. Non-standard screws will cause water leaks, compromising the roof’s structure. Therefore, asphalt shingle roofing fasteners should be high-quality to avoid these problems.
Inexperienced asphalt shingle roof installers may need help with installing fasteners. Improper installation can lead to leaks, rusting, and a void warranty. Following the above tips, you can ensure your new asphalt shingle roof is properly sealed and will last for decades.
Ways to prevent leaks from asphalt shingle roofs
Various factors can cause leaks in asphalt shingle roofs. These factors include constant freeze-thaw cycles, which cause fasteners and seams to loosen and allow moisture to enter. Using the proper sealant can prevent leaks by blocking out moisture and preventing corrosion. However, if you are not experienced with asphalt shingle roofing, getting a professional to do the job is better.
The first step is to check the screws that hold the panels on the roof. You must use the proper pressure to ensure the screws are securely tightened. If the screws have been loosened or damaged, you may need to replace them with new ones. If the screws are loose or missing, you can unscrew them and install new ones flush with the panel.
Another way to detect leaks on asphalt shingle roofs is to check for missing or overlapping seams. These are usually the locations where water can enter. Make sure the seams are well sealed, and check the flashing regularly. Also, inspect the seams between panels. Water will leak through them if they do not seal properly due to the friction created by gravity and surface tension.
Leaks on asphalt shingle roofs can go unnoticed for some time and cause serious mold problems. They can be challenging to detect, mainly if they occur on the ridge, where water can drip directly onto your head. The water can leak and damage your home before you even notice.
The most common causes of leaks on asphalt shingle roofs are improper installation and screwing. This means improperly installed screws will create a hole in the roof, allowing moisture to leak under the asphalt shingle paneling. It is best to hire an experienced roofing company when installing an asphalt shingle roof, increasing your chances of a leak-free roof.
One of the most common places for leaks on an asphalt shingle roof is at the edges. Make sure the seams are properly sealed with butyl tape and sealants. Another way to prevent leaks on an asphalt shingle roof is to check the counter flashing and ensure all sealants are intact and dry.
Tools used
When working on an asphalt shingle roof installation project, the tools used to do so must be high quality. These tools can range from basic implements to specialized ones. For example, a chalk line is necessary to ensure proper alignment of the roofing panels to the underlying weather shielding. Aviation snips are also necessary for cutting roofing material.
Another tool that asphalt shingle roof installers need is an asphalt shingle snip. This tool is essential for cutting the asphalt shingle panel without distortion. A good asphalt shingle snip will make a clean cut through the panel and be easy to handle. This tool is available at Home Depot for around $30 and can be used to make left-hand and right-handed cuts.
Shears are another essential tool for asphalt shingle roof installers. This tool allows them to cut panels quickly and easily on-site. Swenson Shears come with different blades, making the job easier. Nibblers are also helpful for hand-cut panels. Drill attachments are also available that allow for clean, low-cost panel cutting.
The right tool for the job will ensure the roof will be secure and leak-proof. Other tools asphalt shingle roof installers use include a screw gun and a screwdriver. Some contractors also use a cordless drill/driver.
While working on an asphalt shingle roof installation, wearing safety goggles and protective glasses is essential. This will ensure that you avoid any possible injuries. Another essential tool is an insulated work glove. This will help protect your hands from the asphalt shingle, preventing injury to yourself and others.
Another helpful tool is a hammer. This versatile tool can help you get the job done faster. It can be an excellent investment as it will make applying the asphalt shingle roof to your home more accessible. These tools can also help you finish the job quickly and efficiently. They will also save you money on labor costs.
An angle grinder is also a helpful tool. This tool helps asphalt shingle roof installers make precision cuts. It is also helpful for cutting through rebar and fencing. Additionally, it helps prevent sideways water flow through the roof.
Improperly installed fasteners
A critical component of asphalt shingle roof installation is the installation of fasteners. Hundreds of thousands of fasteners fasten asphalt shingle roof panels together. Though many may look similar, they differ in size and performance. A roof designer will specify the type of fastener for a given roof system, but the installer must install each one correctly. Asphalt shingle roof installers should always use the correct type and size of fasteners the manufacturer recommends.
Improperly installed fasteners can damage a roof and cause leaks. Even worse, improperly installed fasteners can damage materials, leading to premature replacement. Improperly installed fasteners also decrease the load rating of the roof. This means your asphalt shingle roof will leak or damage if it can’t withstand the load.
While it may seem like a small detail, improper installation of asphalt shingle roof fasteners can lead to roof leaks, extended maintenance, and other problems. Improperly installed fasteners can also void an asphalt shingle panel’s warranty. An asphalt shingle roof’s warranty can be voided if a professional does not install fasteners.
Improperly installed fasteners can also cause rust on an asphalt shingle roof. Although a rust virus cannot spread from fasteners to the roof, improperly installed fasteners can cause significant damage to the structure. Using suitable long-life fasteners can prevent rusting. It is essential to have a thorough inspection of your roof once a year to make sure that it is in good condition.
Improperly installed fasteners can also affect the longevity of your asphalt shingle roof. If fasteners are not installed properly, the asphalt shingle panels can corrode and leak, and the fasteners can sag and deform. This can also compress gaskets and sealants, reducing their ability to seal the fasteners effectively.
