Having a metal roof is very reliable and durable. They can last for decades without ever needing repair. However, when repair is needed it can end up being quite expensive. After a many years the roof begins to encounter wear and tear as a result of the weather. The roof usually becomes rusty or gets damaged from a storm. Also, if the temperature is very hot it may cause the metal to contract but on the other hand if the temperature is very cold it may cause it to expand. Whatever the case it may be, these are all things that causes a metal roof to require fixing.
In past years roofs were constructed with tin, but nowadays metal roofs are all steel. This steel is either aluminum coated or a very durable polymer is used. However, if any damage was to occur to a metal roof then fixing it can be a moderately easy do-it-yourself job depending on its severity. Otherwise, professional assistance may be in order.
When fixing a metal roof top the first thing to do is pin point the exact location of the damaged area to see if it’s accessible. Also, you should be very careful when going on the roof top simply because walking on it can cause it to dent or even be scratch which you would want to avoid.
A metal patch can be used to fix a metal roof. To do this you should find a metal patch that is the same type of metal that the roof in made out of. Make a rectangle of the metal by folding the sides and nipping off the corners. In order to flux the area you must then wire brush the area. Once this process is complete, you should then solder the patch. To do this you must first place the rectangular patch over the repair area with the folded sides placed downward and then to heat the area use a soldering gun and then join both metals and secure the area, the solder should be applied to the perimeter of the patches.
Another method is to use a roofing mesh. With this method two metal patches are required. Once you prepare the surface by using a wire brush, spread roof cement, using a flat knife over the area needing repair then place the first patch over the repair area. Once this is done, put more roof cement onto the mesh, completely covering it. Work it through very good so that it can join with the undercoat and then put the second patch on top on that coat of roof cement. Once this is done, you want to again work in the roof cement so that it meets the previous coat of roof cement.
If in any event the damages are really severe then you should check the rafters and any other area that may have been affected as a result. Before you begin to fix the metal roof you should remove any water that may have settled in or around the area. Then you should proceed to loosen all screws along the J-rail where the new material is going to be overlaid. Loosing the J-rail allows the new sheet to slide underneath with no problem at all. Then, thoroughly inspect the damage area for any other damages needing to be replaced or repaired. If any water needed to be removed from the repair area let that area dry first. Then measure the damaged area and cut the sheet the same length of it. At the end of the sheet apply butyl-tape. Preferably two inches, this is done so that the edges will stick to the J-rail and hold. Then proceed to tighten the loosened screws.
Metal roofs are very durable and sustainable. It's always comforting to hear the rain as it pounds against the metal. However, it can be very costly and challenging when it needs to be fixed. Fix metal roof can add up to about double or more the amount of regular shingles when it's time for repair but it can last to almost fifty years once repairs are made. So in any event having a metal roof is well worth it.
