Southport Roofing: Article About How To Maintain A Metal Roof
One of the leading reasons why so many homeowners are choosing to have a new metal roof installed onto their houses is the ease of maintaining such a roofing system. Once the installation is complete, metal roofs require considerably less maintenance than an asphalt shingle roof. With annual checkups performed by experienced Southport roofing contractors, property owners can enjoy decades without problems from their new metal roofs.
There are several areas of a metal rooftop that require preventive maintenance. The fastener gaskets may experience cracking, rust or corrosion. These should be replaced at the first signs of wear and tear. A loose or damaged fastener could cause the metal panels to loosen, which can lead to damage in severe weather conditions. Roofing nails, bolts and clips should also be checked to ensure that they are securely attached to the roof's wooden framing. If a fastener has popped up, broken or gone missing, it should be replaced as quickly as possible. The hole around a damaged or missing fastener could allow condensation and precipitation to reach the interior of the house.
Perimeter and penetration sealants should also be inspected.

Most silicone and petroleum-based sealants have a lifespan of 20 years, but this can be shorter if the metal has direct exposure to sunlight or has experienced severe storms. Intense heat, air pollution and exposure to acids can also wear away at the sealants. Contractors can peel or scrape off the old materials and reapply a new layer. The new sealant cures within 12 to 24 hours under dry conditions with low to moderate humidity levels.
The joints between metal panels also deserve attention. Temperature changes from day to night and season to season cause metals to expand and contract. This expansion and contraction may cause seams to come apart. All seams should be sealed and the sealants checked once per year. Seam leaks and obvious seam separation are a leading cause of leaks in metal roofing systems.
Surface maintenance is also important for the structural integrity of a metal roof. If the rooftop has a coating such as paint, acrylic or ceramic granules, the coatings may need to be touched up to prevent corrosion of bare areas. Any scratches, dents or dings should also be repaired so that water cannot intrude into the area and cause rust. Roofers may be able to repair large dents and small holes by soldering a strip of the same type of metal to fill the low spot or using roofing cement to fill in the depression.
