Maintaining your metal roof can require some effort at times. Through harsh weather conditions, your metal roof might face some damage from the elements. One of the issues you might run into with your roof are holes. Holes can form in any type of metal roof, regardless if it is tin or steel. Though metal materials such as steel are incredibly durable, a heavy impact can still cause some damage. This damage can come from large hail stones, rocks or even flying debris.

However, if you find your steel roof has formed some holes, you don't need to worry. In many cases, you will be able to repair small holes yourself; without calling in an expensive professional. There are a number of supplies that you can purchase, which will allow you to fill up holes without leaving any major markings. Two of the most effective supplies for fixing holes on a steel roof are silicone and polyurethane sealants. 

Silicone Sealants

When you are looking to purchase a silicone sealant for your steel roof; it is important that you choose a silicone that matches the color of your roof. This is because you cannot directly paint over a silicone sealant, so it is important that you choose the right color. A silicone sealant has a number of benefits that make it perfect for covering holes on a steel roof. Here are a few:

• It is non-corrosive
• Silicone locks out water
• It is available in a variety of colors to match your roof

It is important that you choose a product that is 100% silicone-based. This is because some brands will use unnecessary fillers that can effect the quality and durability of the sealant.

Polyurethane Sealants

Polyurethane sealants are also a great option for covering holes on a steel roof. Polyurethane sealants will often appear like a type of paste. The paste itself will harden and cure when exposed to atmospheric conditions, such as heat or evaporation. Unlike silicone, most polyurethane sealants can be painted over, which can be effective if you cannot find a silicone color that matches your roof. Here are some of the benefits of polyurethane sealants:

• It can be painted over
• Elastic
• Non-corrosive
• Bonds well to steel

There you have it. If you are dealing with small holes on your steel roof, these two supplies are perfect for covering them up. If you are dealing with a large hole, it is recommended that you call up a professional to avoid injury.
