Metal roofing is known for having a long service life, which you can prolong by installing a restoration system once the roof shows signs of age. Acrylic coatings are a popular type of restoration system. These water-tight coatings are typically light in color, which will also reflect heat and increase the energy efficiency of your building. The following are just some of the signs that it is time to restore your metal roof.
1. Popped Screws
Screws pop up on metal roofs primarily in response to major temperature swings. The temperature-induced expansion and contraction of the metal panels and underlying wood supports will push the screws out. Water can then leak in around the popped screws. Roof restoration coatings, which are applied after the screws are seated back in place, can lower the roof's temperature and prevents major fluctuations. This in turn minimizes the chances of popped screws.
2. Seam Separation
The same temperature swings that cause popped screws can also lead to seam separation between panels. This is most common on metal roofs that do not feature an interlocking panel system. A roof restoration will serve two purposes in the event of a seam separation. First, it reduces temperature fluctuations and prevents any further separation. Second, the coating will seal any seam gaps so that water can not leak through. The result is a more watertight roof.
3. Finish Failure
Over time the paint on the metal roof will begin to fail. Peeling, flaking paint both looks bad and compromise the integrity of the roof. Once exposed to the elements, the metal roof panels can begin to develop rust or corrosion. Rust eventually eats holes through the metal and causes lots of small leaks. Roof restoration entails removing any rust that has begun to form and then painting on the roof coating. The coating provides a fresh finish that will prevent any rust from forming.
4. Small Leaks
If your panels have already developed small pinhole leaks, then a coating is the best solution. Larger leaks can be patched, but lots of small leaks are hard to track down effectively for individual patching. A restoration coating is applied evenly over the entire roof surface. The coating effectively creates a membrane that can cover small leaks so that they are no longer a concern.
