You plan on your new metal roof being the last roof you put onto your house. You can expect to get from 40 to 80 years from your metal roof. Here are a few maintenance tips to make sure you get the maximum amount of service from your roof.

1. Keep debris off of your roof and power wash yearly

Sweep branches, limbs and other debris off of your roof whenever you spot it. Clean your roof off after a storm that might dump material onto your roof. The debris blocks the water from flowing off of the roof which causes rust spots and leaks around fasteners. Power wash your roof every year to get debris out of the creases, from under the edge of the peak, and out of the gutters.

2. Replace and Secure Fasteners

If you notice screws working their way out of the roof, tighten them down to get a good seal. If you notice rust around a screw, replace it with a new one. Any screws completely missing should be replaced immediately before water can get under the metal sheets. Make sure to use screws that are the same material as the roof. Different metals touching each other, such as galvanized steel screws on a copper roof, will create a chemical reaction resulting in corrosion.

3. Touch Up Scratches and Flaking Paint

Wherever you see damage to the metal sheets that exposes the bare metal, cover it with paint or a sealer before rust can start. A small scratch can allow rust to set in and work its way under the paint. This can create a large rust spot you may not see until the paint covering the spot falls away.

4. Re-seal Seams and Edges When Necessary

A waterproof sealant is used to protect the seams where the metal sheets join and the edges of the roof. If you notice places where the sealant has dried up, cracked or fallen out, replace it immediately so water can't get under the metal roof. You can find the metal roof sealer in small tubes, or large cartridges for use in a caulk gun.

5. Keep water flowing through your gutters

Keep your gutter clean so water doesn't back up and touch the edge of your metal roof. Should your gutter become bent and touch the roof, bend it away so corrosion won't start where the two different metals touch.

6. Walk on your roof with care, or not at all

Working on a roof is dangerous and best left to roofing contractors. If you must put a foot on the roof, step on the seams where the metal is thickest and less likely to bend under your weight. Do whatever maintenance you can from a ladder and leave painting and repairs in the center of the roof to a licensed roofing company.
