A tin roof is one of the oldest types in the roofing industry. Although not very common, a tin roof has several advantages. It is one of the most affordable roofs available on the market. It is also fairly durable. Regular maintenance helps to give it an even longer life span. Perhaps you have a tin roof on your house or some other structure in the home. It helps if you know how to maintain it. Some tips are given below.
A common problem with tin roofing is corrosion. To prevent this, you may choose to repaint your roof every 2 to 4 years. This also helps prevent rust. Use a paint that is especially formulated for metal roofs. Prepare the roof well before you paint. Use a scraper or wire brush to remove loose paint and rust. You must then clean the roof with tri sodium phosphate. A clean surface gives better results when you paint. It is best to touch up the paint in areas where you notice it beginning to wear off.
Use of a protective finish can help to maintain your tin roofing in good condition for longer. A polyvinylidene fluoride (PVDF) finish is one of the best available on the market. This has high weather resistance properties. It helps to prevent rust, corrosion and mold problems. A PVDF finish also increases the resilience of your metal roof. Once applied, it helps to maintain the roof in good condition for at least 10 years.
3. Holes and Open Seams
These may develop on your roof with time due to exposure to the elements. It is best to fix holes and open seams as soon as you spot them. Patch up large holes with a piece of tin. Get a section of tin that is slightly larger than the hole. It helps if you have tin snips for cutting out the tin patches. Apply some flux around the hole and then patch it up. Use a soldering iron to secure the patch in place. You can also use roofing cement on small gaps. Re-caulk open seams with urethane roof cement.
4. Avoid Use of Different Metals on Roof
It is best not to use different types of metal for repair work on tin roofing. Chemical reactions may occur between the different materials that encourages corrosion. Be sure to use only tin screws to secure the roof. Use the screws only on raised sections of the roof. The screws should also have washers to help prevent the collection of water around them. This helps to hinder leakages, corrosion and rust.
5. Attend to Repairs Quickly
It is best to undertake repairs as soon as you take note of damaged sections on your roof. The longer you put if off, the more extensive the damage becomes. It also ends up being more costly. It helps if you have repair materials readily available in your home. It is a good idea to inspect your roof regularly. This will help you spot the problem areas in good time.
