6 Metal Roofing Mistakes To Avoid
Metal roofing is one of the most durable roofing options. It can last for more than 50 years. One can reap the benefits of metal roofs provided they are properly installed and regularly cleaned. Poor installation practices can make the whole investment useless. It would not be wrong to say that hiring incompetent metal roofing contractors can be your worst mistake.
One can steer clear of the mistakes if they understand the consequences and possible alternatives of the common metal roofing mistakes. According to the experts, here are the top 6 metal roofing mistakes to avoid.
1. Using Poorly Sized FastenersHiring the best metal roofing contractor in Cary NC is important for various reasons. Using the perfectly sized fasteners is as much important as the quality of metal panels. The size of the fastener makes a difference when it rains.
Every homeowner understands the risks associated with water leaks so it is easy to comprehend the importance of using the right fasteners. If the metal panels are secured using standard-sized fasteners, the water can easily seep through them. High impact winds can easily dislocate the panels and you are left with a damaged roof.
Read the instructions provided by the manufacturer. If there is a suggested fastener size, make sure you find them.
2. Picking The Wrong SubstrateWhen you look at the metal roof, you can't see the substrate or underlayment. This hidden part of the metal roof plays a pivotal role in its durability. Most of the metal panels are designed to be installed over solid substrates such as plywood.
Experts recommend using solid substrates, especially for the smaller homes. In some cases, battens are also effective but opt for solid substrate whenever possible. The risk of using battens as the underlayment is the development of condensation. The moisture builds up under the roof panels can seriously affect its integrity.
3. Inadequate Panel OverlappingAlmost all of the metal roof panels are designed to overlap each other. The design is effective in preventing water leaks from the seams. The size of the overlap generally depends on the slope of the roof. It is best to study the instructions provided by the manufacturer. Calculate the roof pitch and then use the numbers given in instructions. Abide by the rules and you can avoid the risks of water damages.
4. Leaving Improper OverhangsRoof edges are very important in evading the water damages. Make sure your metal roof has properly sized overhangs. If the metal panel is cut too short, rainwater can seep to the substrate. This is the last thing every homeowner would want! The water can also leak down to the sidings. Damages to the house exterior can lead to greater more serious problems such as pest infestation.
Leaving too much overhang is another bad idea. If the edges are extended for more than two inches the rainwater overshoot the roof gutters and fall to the ground. The whole purpose of the gutter system is lost. Experts recommend the overhang should be between 1.5-2 inches.
5. Miscalculation Regarding Roofing MaterialsPicking the best type of metal roof is one thing and calculating the required material is another. Some of the online resources help simplify the calculations for you. It is highly recommended to seek professional assistance to get done with the complex measurements.
6. Poor MaintenanceIf you want to make the most of your roofing investment, make sure you follow a roof maintenance schedule. The most important maintenance rule is to prevent your roof against corrosion. Make sure there is no other metal in touch with the roof panels.
