Getting The Most Out Of Your New Metal Roof

by Howard Barnett

Your new metal roof could give you up to 80 years of protection. To make sure you get the most from your metal roof, have it inspected every year by a roofing company. There are also a number of routine maintenance tasks that you can do to keep your metal roof looking good and working efficiently.

1. Keep any debris cleaned off of the roof.

Anything on the roof that prevents water from draining off can potentially allow rust to develop. Leaves, sticks and branches from overhanging trees can create a dam that allows water to pool on the roof. If the water is sitting over a place where the metal sheeting has been scratched, rust can start and make its way under the protective coating. If there are any loose or missing screws under the debris, water can make its way under the metal sheet where it isn't coated and form rust. Sweep or hose off any material that you see sitting on the roof to prevent this.

2. Keep the gutters flowing and in good repair.

A blocked gutter can allow water to back up and touch the edge of the metal roofing, where it may not be protected. Rust can start at this edge and work its way up under the coating on the metal sheet.

If a portion of the gutter becomes bent or twisted and touches the metal roof, you can have a different problem. When two different metals touch each other, a chemical reaction starts that accelerates corrosion. For example, a galvanized steel gutter touching a copper roof can damage the metal sheet and allow corrosion to begin. Repair any gutter damage quickly.

3. Replace any missing screws and tighten any loose connectors.

A windstorm can force the metal sheets up off of the roof resulting in loose screws or screws that come completely out of the roof. These connection points can let water under the metal sheets. Tighten any screws that have partially backed out of the roof and replace all missing screws before water finds its way under your roof.

4. Periodically check the flashings to make sure they are sealed properly.

Any opening in the metal roof, such as vent pipes or a fireplace chimney, will have a metal sheet called flashing around it. This sheet is screwed onto the metal roof and has a coating of roof sealer placed between it and the item sticking up out of the roof. This is to prevent water from getting under the roof from around the item. Check that the flashing is securely fastened to the roof and that the sealer is intact. Cracked or missing sealer should be removed and new sealer forced from a tube or caulking gun between the flashing and the metal roof sheet.

5. Re-coat the metal roof as per the manufacturer's recommendations.

The metal coating applied to your roof when it was installed provides protection from water and reduces some of the ultraviolet rays from the sun, which keeps the roof cooler. Over time, the coating wears down and needs to be re-applied. Have a professional roofer, like those at East Texas Roof Works & Sheet Metal LLC., apply the coating to make sure all areas of the metal roof are protected.
