Maintaining a metal roof may be easier than caring for a shingled roof, but the commitment to care is just as important. While metal roofs require fewer repairs and less maintenance overall, ignoring minor issues can turn them into major ones, leading to extensive (and expensive) repairs. You should focus on metal roof maintenance specifically in the months leading up to the cold winter season.
Add or Replace Attic Insulation and Venting Systems
Installing a metal roof does not negate the need to ensure your insulation and venting systems are adequate and fitted to your roof’s needs. Have a professional roofer conduct an energy audit in your attic. Add additional insulation if the attic is too warm, and customize the venting system to achieve maximum effectiveness in removing hot air and eliminating moisture buildup.
Remove Debris from the Surface
Maintaining a metal roof also involves regularly clearing away the leaves and sticks that may collect on it. Follow your roofing contractor’s guidelines for metal roof cleaning, using a hose or pressure washer if recommended, or hire a professional to take care of it for you.
Trim Surrounding Trees and Brush
If overhanging branches brush against your metal roof, they could scratch and damage the sealant coating. Trim away any branches that threaten your home’s metal roof — if water penetrates the seal, it could cause rust and corrosion.
Don’t Neglect Your Drainage System
Metal roofs are durable, but they are susceptible to degradation as well. If you allow your gutters to get clogged, standing water could keep the edge of the roof wet for long periods of time. Metal should be exposed to as little moisture as possible, otherwise corrosion may begin to eat away at the roof’s edges. Keep your gutters and downspouts clean and you will avoid this issue.
Watch for Rust and Corrosion
Never let two different types of metal touch each other and co-exist in your roofing system, especially when extreme weather is on the horizon. The chemical reactions that take place among varying types of metal can lead to corrosion that weakens your roof. If you spot rust developing in any area, call a dependable roofing contractor to address the problem right away.
Replace Sealants and Repair Holes Immediately
Metal roofs differ in the types and shapes of material used for installation; however, most metal roofs are made of sheets which are installed on the roof deck. The sheets are fastened together and sealed or bonded, depending on the contractor’s method and the type of metal.
Where these sheets meet, water damage can and will occur if gaps appear and water is allowed to penetrate. Metal roofs may expand and contract with temperature fluctuations, loosening screws and creating spaces. It is important to have the roof regularly inspected for seam leaks and make sure any gaps are repaired right away.
