Common Questions About Metal Roofing Answered

If you're considering having a metal roof installed on your home, you probably have lots of questions that you're looking to have answered. Here, you'll find some of the most common questions about metal roofing and the answers that you seek.

Does metal roofing resist moss and algae growth?

Moss and algae growth can be serious problems on roofs. Unfortunately, yes, the metal roofing can grow moss and algae, but only if you don't do your part in keeping up with the maintenance. If you keep the roofing free of dirt and debris, the moss and algae will not have the organic material it needs to root and thrive.

Can metal roofing be cleaned?

Yes! Metal roofing is actually quite easy to keep clean. All it takes is a hose and a soft-bristled scrub brush. If you clean your roofing once or twice each year, it will stay in good condition. If the roofing is extremely dirty, you can use a pressure washer to clean it, but you must be careful not to shoot water directly at the seams. Water can penetrate the seams when it's blown in with that much pressure – just watch the seams.

Will metal roofing fade?

Unfortunately, yes, metal roofing does fade over the years. Sun exposure, temperature, moisture, and the quality of the metal roofing finish will determine how much the roofing fades. Some manufacturers do include color-fast warranties on their products. These warranties are spelled out very clearly and do not typically protect against minor fading. There are measurements for determining how much something has faded – these measurements are used to determine if the warranty will cover the repairs or not.

Can metal roofing be installed over asphalt shingles?

Yes and no. Reroofing over existing roofing materials isn't always a smart option. When the shingles aren't removed before a new roof is installed, you're opening the door to all kinds of potential problems – you don't know what the roofing under the shingles looks like and if there is a roofing fire, it will be much more difficult to extinguish.

Before you decide if metal roofing is the best option for your home, stop and talk with a professional roofing contractor. He or she will take a look at the roof of your home now and help you come to the best possible decision that will keep your home looking great for years to come.
