Will A White Metal Roof Stain?

Mold, mildew, moss, and algae can cause metal roof stains. These growths are typically seen on shaded roofs and are particularly common in rainy or humid coastal environments.

The moisture and humidity in these areas encourage the growth of algae, particularly on new metal construction.

White metal roofs pose no unique wood preservation challenges. Because of their naturally durable nature and ability to resist mildew, molds and mildews are rare and usually only an issue when the roof system is old.

White metal roofing needs to be kept free of moisture by wearing a rubber roofing boot or other protective covering when working on the roof. If a mildew or mold problem does develop, you can use contact cleaners for steel screws to remove moisture from within your metal structure.

Will An Indoor Antenna Work With A Metal Roof?

Metal roofs (as well as other construction materials comprising metal and thick stone) will not allow signals to travel through them. They will cause an antenna installation to fail if the antenna site is chosen without considering the signal’s route.

The best case is a metal roof-free site with a clear, unobstructed path to the highest in-building point of the antenna’s signal.

We recommend mounting your antenna on the gable side of a metal-clad house; this way, you’ll have an unobstructed path between your house and the nearest television tower or radio transmitter.

Most antennas need to be mounted close to the high part of a building to get good reception. If you mount your antenna on any other exterior surface, it may not perform properly and may interfere with TV broadcasts.

Will The Black Metal Roof Fade?

As a general rule, black roofs suffer from the same problems as all roofs. They’re more vulnerable to sun damage, rain, and snow than white or tile roofs.

Oxidation and discoloration of the surface materials occur in about 5-10 years, by which time you may have to replace your roof.

Will Bleach Clean A Metal Roof?

Yes, a diluted bleach solution may remove stubborn stains from your metal roof. Roof cleaning solutions containing chlorine bleach are also effective for cleaning mold, mildew, and algae from the surface of your roof.

The cleaner must be prepared properly and used in the right way to prevent damage to the surface material.

It is vital that you read all manufacturer instructions before attempting to clean your roof. If a strong acid or alkali is used in order to clean or remove rust from metal, the results will be disastrous.

The most common solutions for removing rust are vinegar and citric acid (the acidity of orange juice), which is available at many grocery stores) diluted with water.
