Metal roofs can seem like an ideal option for your home, but they do have some drawbacks. It’s crucial to know about the downsides before you get a metal roof installation. If you decide to go this route, there are some things you can do to minimize or avoid issues.
1. Roof Leaks
Metal roofs may leak after enough wear and tear. The UV radiation and fluctuation of temperature and other extreme weather can wear metal down at a faster rate. Be sure to clear out debris and inspect the seals and flashings regularly.
Roofing professionals should identify even minor leaks as soon as possible after you notice them so that you can prevent further damage. They can replace panels, seal gaps, and put on coatings to reduce the risk of corrosion.
2. Corrosion
Speaking of corrosion, it’s important to note that metal is a material that may corrode over time. Some causes for this include moisture exposure from rain and other weather events, salt exposure from deicing or being in a coastal region, and chemical reactions due to cleaning agents and other things containing chemicals. Sealing up gaps and performing regular inspections are important to avoid corrosion.
3. Thermal Contraction and Expansion
Metal roofs tend to contract when exposed to colder temperatures, and they expand when it becomes hotter outside. This causes stress for the roof panels. As a result of this contraction and expansion, your roof may develop gaps. Some measures that can be taken include using clips or fasteners to allow for panel movement, applying reflective coatings to minimize temperature fluctuations on the roof, and installing expansion joints to help reduce stress.
4. Energy Efficiency
Metal roofs often absorb and retain heat. Metal also transfers the cold. In these instances, homeowners are likely to use more energy when it comes to temperature control inside their houses. To help improve the energy efficiency of your roof, opt for reflective coating, a roof design that reflects sunlight, and/or a specialized ventilation system.
5. More Dents
You’re more likely to get dents on your roof if it’s made of metal. Softer metals such as aluminum dent more easily than harder metals like steel. While it’s not possible to completely avoid dents from hail and debris landing on your roof, a regular maintenance schedule and repairing minor dents can extend your roof’s lifespan.
Metal can be a good material for a home roof, as long as you’re aware of the disadvantages. Proper installation and maintenance services truly are necessary to keep your metal roof in good condition.
