Metal Roof Repair – Keep Your Roof in Good Shape!
The roof is basically the first and only line of defense that protects the comfort of your home from detrimental environmental elements. That’s why proper maintenance and timely repair are extremely important.
As you probably know, the main metal roofing materials are stainless steel, aluminum and copper. Metal roofing is usually installed in the form of sheets or panels (even if it looks like individual shingles). The roof can be left unfinished (this is possible only in case of galvanized steel or copper) or coated with a variety of metal roofing colors and finishes which increase its durability, also making it more attractive and stylish.
Metal Roofs are One of the Most Durable Solutions
Metal roofing is the most durable roofing system available nowadays. Unlike other traditional types of roofs (asphalt, wood or stone), it is immune to decay, mildew, insects and fire. However, nothing lasts forever. In time, a metal roof will become vulnerable to leakages, especially if it’s made from low quality materials and it lacks proper coating. Generally, the most durable materials (galvanized steel, aluminum and copper) need less maintenance. If, for example, an asphalt roof has to be repaired at least once in 2 years, a quality metal roof will require small repairs only after 10 years of use or even more.
Metal Roofing Materials
Every type of metal roofing material should be repaired in a different manner. That’s why, if you don’t have enough experience in the field of metal roofing repair, you should seek the help of a professional contractor.
For example, a rusty iron barn roof should be handled differently than galvanized stainless steel or unfinished copper. On the other hand, there are some common repair strategies that apply to all types of metal roofing.
As I already mentioned, leakages are the main enemies of metal roofs. They happen when the panels get loose as a result of prolonged exposure to rains, snow and strong winds. In the case of standing seam roofing, these tiny gaps can occur at the seams, resulting in leaks.
The most difficult thing is to identify the exact damage spot. This usually requires a rigorous inspection of the roof surface, especially at the seams and near the areas around vents and chimneys. Rusty tiles are more likely to be damaged or loosened.
Metal Roofing Repairs are Important
Before attempting any repairs, clean the roof thoroughly by using a pressure washer, a broom and a wire brush (for removing corrosion). As a matter of fact, if you want to prevent unpleasant leakages and increase the longevity of the roof, it’s recommended to perform cleaning and inspections every year – this way you can identify problematic spots in time.
If the damage is extensive, you may need to replace the metal sheet or panel. I strongly recommend hiring a specialist for doing this job – until he arrives, you should cover the spot with a waterproof tarp. If the damage is minimal, on the other hand, you can try performing the repair on your own.
After cleaning the area, fasten all the screws in place so that the panels/tiles are securely attached to each other and the underlying supporting structure. Apply patching cement at the seams (or the other deteriorated areas). When the cement has dried, apply a layer of metal roof coating – it will create an impenetrable membrane that will prevent further leakages.
Another important aspect of metal roofing repair is the fact that modern paints, finishes and coatings can easily replace serious repairs, especially if maintenance work is performed regularly.
