4 Common Metal Roofing Problems

Roof Leaks

Roof leaks are one of the most common problems that homeowners experience with metal roofs. Poor craftsmanship often results to gaps and punctures in metal roofing, making leaks more likely to occur. Leaks tend to grow over time, so if you notice a leak, make sure to address it as soon as possible. You’ll likely end up saving yourself a lot of money and stress.


Blow-offs may also occur as a result of poor installation. If flashing is poorly attached, for instance, open seams and laps can cause parts of the roof to blow off. To avoid this, make sure to have your roof installed properly by a professional contractor and check regularly for problems. Preventing blow-offs initially can save you from costly roofing repairs later.

Perhaps you have a corrugated tin roof in your home. This isn’t one of the common metal roofing materials. The use of steel and iron for roofing appears to be more widespread than tin. However, a tin roof isn’t without its benefits. Tin is one of the cheapest metals you can choose for roofing. It is also highly durable. Tin doesn’t suffer from corrosion unlike iron and steel. Older corrugated tin roofs are likely to show signs of damage. This includes rust and holes which create leakages. Fortunately, it doesn’t take too much to repair the roof. Below are the steps you can take when you repair.

Step 1 – Sweep

It is best to sweep your tin roof first. This will enable you to see the entire surface more clearly and identify the areas in need of repair.

Step 2 – Rust

Use a wire brush to scrape away rusted areas on your roof. Strive to clear away as much of the rust as you can. Some holes may have developed in rusted spots and it is best to repair a clean surface. For rust that proves difficult to clear, apply some mineral oil onto the rusted areas with paper towels. Allow the oil to soak in well for about 30 minutes. Scrub the area with a brush to facilitate rust removal.
