Eight metal roofing installation mistakes
Residential metal roof should be installed carefully, responsibly and by professionally trained people. An assembly error can cause a serious problem that may lead to another problem. No home owner wants that. Therefore, you must know to watch for a few mistakes when you want a metal roof installed on your house. This will relieve stress, nerves and money spent unnecessarily. Surely you do not want to have leaks in your house because of the roof which you contracted a federal credit for. Certainly neither the company that has advised you, does not want that. So, let’s see what we should be careful of.
Before installing the metal roof, one should check the old roof’s material condition. A rotten wood and saturated with excess water can weaken the roof again. The contractor must ensure that the old roof structure requires no preparation work. The metal expands and contracts, so it can do much damage if the place where it has to be installed isn’t correctly checked and prepared.
Metal roofs are lighter than conventional roofs, such as shingles, concrete, asphalt or wood in several layers. However, if the new metal roof is installed over the old roof, it is advised to consult a specialist in the resistance of a building structure. It is possible that a surplus of weight may not be supported by the resistance elements of the house. An architect can tell you exactly what to do: install over the old roof or not.
An installer is not always a producer and general assembly manufacturers have teams for their own products’ installation. Each metal roof can be customized, while each type of roof has its own installation instructions. Roof manufacturers warrant only where his instructions have been rigorously followed. So, make sure you know the installation instructions, for the collateral risk taker is the homeowner, not the roof installer. Metal roofing systems can lose the guarantee even before being mounted, if compromises are made and the manufacturer’s installation instructions are not met. Even an insurance company is paying attention to this details.If you decided to install a metal roof panels system over the old roof, be it from shingles, wood, concrete or asphalt,have a discussion with your insurance company. it is very important to know that some insurance companies are unwilling to issue insurance policies for such works, at best you may end up with your home insurance costs doubled or tripled . Certainly you do not want that.
The delivered metal roofing systems may contain manufacturing errors. A contractor from too much excess of zeal, may not take into account the defects, he wants to do the job quickly, take your money and go. The installer can offer a warranty for the work, but if something goes wrong ,you blame the manufacturer and producer will blame you for not having checked what you bought. Therefore, make sure that what you are buying is in proper condition.
Metal roof panels must be perfectly sealed . If you hire the cheapest contractor for such work, you can expect him to not do the work properly, he can leave negligible cracks or parts of the roof not sealed perfectly. It is therefore possible to have water leaking in your house. An insignificant hole in your metal roof can lead to real early drainage channels just below the roof, causing significant damage.
Make sure that when the contractor installs the metal roof, he doesn’t step on it very often. A great foot traffic on it ,can become a problem over time. Avoid climbing on the roof even after installation, since the debris from the roof are cleaned by the rain, if the owner wants to manual release the impurities and residues from the roof, it is recommended to use ladders and brushes with very long tail, avoiding as much as possible to step on it.
Finally, a very serious mistake that an installer of metal roofing can make is the following: under the roof panels, boards with granular surface are installed, which is totally wrong. Wood panels are designed to seal and make the barrier between a damaged metal roof and the house structure, and they should be shiny, smooth and non-abrasive because metal roof expands and contracts.
