Metal roofs are well-known for their durability and long life. However, if your metal roof should acquire damage at any time, you should call a metal roof repair expert right away. The following examples are three types of metal roof damage and how they are commonly repaired.
Holes, or puncture marks, are created when something large enough, sharp enough, and/or traveling fast enough smashes through the metal roof. You can bet that if the object is able to do that kind of damage to copper or galvanized steel, it probably went all the way through the roof into your attic too. That means that you not only have to repair the hole in the metal, but also the hole in the attic.
To fix this, the roofing contractor will first have to go into your attic to see the damage from underneath the hole area. If it is particularly bad, he or she will need to take roofing material off from the outside, replace the wood and (if applicable) any rubber roofing underlay or old shingles. Wood, rubber, etc., all have to be replaced before the hole in the metal roof material can be patched or replaced.
If the damage is not that serious, the hole in your attic can be patched both from within and without. Inside your attic, a thin piece of wood is applied over the hole. Outside, a wood filler is used to create a plug for the hole. The underlying materials under the metal roof are replaced. Then the hole in the metal roofing material is patched or replaced. Usually, a little welding and a metal patch is sufficient for any holes smaller than a silver dollar. Complete replacement of the material is necessary for holes larger than an orange.
Tears or Tear-Offs
It takes some serious force to tear or tear off pieces of a metal roof. It would have to be a mach 5 tornado or level 6 hurricane to manage it. If this is the kind of metal roof damage you have, there are two approaches to take.
One, the roofing contractor can weld the metal roof back together. This only works if the roofing materials underneath are undamaged by the same storm that managed to damage the metal. Rips shorter than your arm are welded back together, and then re-secured to the rest of the roof with fasteners. Bigger rips are often handled as tear-offs.
Two, large tears and tear-offs mean that this section of the roof has to be replaced entirely. Your roofing contractor will have to take this entire section off, including any damaged materials underneath, and install all new materials. Thankfully, your entire roof will not have to come off to accomplish this task unless the storm tore off more than half of your roof (and that is quite the feat!).
Caved-in metal roofing is exceptionally rare. This would mean that either the entire roof under the metal roof has rotten to the point that it caved in and the metal roof followed, or something the size of a redwood tree fell on the roof and crushed it. Either way, this is the most serious type of damage possible, and luckily, your homeowner's insurance should cover it.
Overall, this is a total tear-off and rebuild project, since your roof will have to be rebuilt in order to support the metal roofing material. It will take a week or two, so if your bedrooms are on the upper floor, you may want to relocate for the first week. As soon as the new roof has been constructed and is covered and ready for the metal roof, you can come back to the house.
