If installed properly, your new metal roof can last up to 80 years. To ensure that your roof lasts this long, you need to care for it properly. Below are some maintenance items you need to add to your to do list so you can keep that beautiful roof over your head.
Keep the Paint Touched Up
If any paint on the roof comes off, rust can form after a rain or other extreme weather in this area. For this reason, you need to touch up the paint in all areas as soon as you notice this. Contact your roofing contractor and ask them the type of paint you should use. They can likely provide you with the paint, as well as the right color.
You should remove debris from the roof, such as sticks, leaves, and tree branches. This not only makes your roof look unsightly, but as the debris decomposes, it can damage the roof finish over time. Rain will rinse away most of the debris, but there will likely be some left on it. You can use an extendable window cleaning brush that has soft bristles to pull the debris off. If you use a garden hose, you need to be very careful. If you use a hard water jet, it can easily push water under the roof, which will cause leaks in most circumstances.
Tighten or Replace Roof Fasteners
Another maintenance item that needs to be done is to tighten or replace roof fasteners. If they are loose or damaged, water will get under the metal panels. The wood rafters will become wet and rot, and rust will develop. Over time, this can cause great damage, so make sure you check this at least once a year. Tighten or replace any nails and screws that are loose or missing.
Make Sure Flashings Are Secure and Sealed
Flashing covers and surrounds the openings on top of your roof, such as chimneys and plumbing vents. Water can seep into these areas if the flashing is damaged in any way. This is because the flashing acts like a watertight seal. Over time, flashing can deteriorate and can become loose, causing leaks in your roof, as well as damage to the sheets. Look for holes made by roofing nails, bends, and gaps. If you find problems, you will need to re-caulk the flashing.
Consider recoating your metal roof in approximately 5 to 12 years. This will keep it protected from the elements, including hail and ice storms and ultraviolet (UV) radiation.
