Metal roofs are sturdy and long-lasting, but they're not immune to issues. Like any other type of roofing system, metal roofs can experience problems from time to time. This article discusses three common metal roof problems and how to fix them.
Metal roofs may be prone to leaks due to several reasons. First, seams between pieces of metal can develop small holes or cracks over time, which increases the risk of water infiltration.
Second, metal roofs may be installed improperly. If corners or other parts of the roof are not sealed completely and securely, moisture can get in more easily. Finally, metal roofs tend to expand and contract with temperature changes, which puts added stress on the roofing material and increases the risk of leaks.
To prevent these issues, licensed roofing contractors will typically carry out a series of steps when installing a metal roof. This process often includes thoroughly sealing all seams and corners before putting on the final protective layer.
Additionally, contractors will ensure that any vents or other items that penetrate the roofline are appropriately sealed and weatherproofed. These measures can prevent moisture from getting in through the openings. By employing these strategies, contractors can provide homeowners with a secure and leak-free metal roof that can withstand even the most intense weather conditions.
Corrosion is another common issue with metal roofs. This problem is most likely to occur in areas with high humidity, as these environmental conditions can accelerate metal breakdown. Corrosion can also be caused by low-quality metal roofing materials, poor installation, or exposure to chemicals.
To prevent corrosion in metal roofs, roofing contractors may apply a waterproof sealant or paint to the roof's entire surface. These materials can create a barrier that prevents water and moisture from seeping into the seams and joints of the metal sheeting. Particularly where cracks may develop over time, a sealant can provide an extra layer of protection against water damage.
In areas with high humidity or salt air, contractors may also recommend installing a ventilation system beneath the metal roof. This system can help circulate air and prevent the buildup of moisture, leading to corrosion.
In addition, contractors will often recommend installing gutters along the edges of a metal roof. This diversion can direct excess runoff away from the roof's surface. By taking these measures, roofing contractors can help prevent corrosion and extend the lifespan of metal roofs.
