Disadvantages of metal roofing

Metal Roofing Denver

Many pages have been written about metal roofing. Typing the words "metal roofs" in the Google search engine, you will find over 11 million pages with references to this kind of construction. Some companies describe the metal roofs as 100% favorable. The fact is that this is true. Disadvantages found by some owners of residential houses   are just the result of a manufacturing deficiency or errors of metal roofing installers. Let’s see about what disadvantages we are talking about.

Metal roofs materials are heavier than conventional materials used for conventional roofs. It is a misconception that is not valid unless people generalize. Yes, a metal roof is heavier than an asphalt roof, but asphalt begins to deteriorate immediately after the house was built. The weight of a metal roof can become a problem when the house has very degraded structural strength. In general, metal roof systems are very light compared to conventional alternatives. The weight of a metal roof is highly dependent on the amount of metal panel profile used.

Metal roofs are very noisy. Yes, when it rains heavily or hail falls, a metal roof can become noisy. However, if you’re one of the residential homeowners who love the sound of rain on the roof, a special sound insulation for a metal roof can eliminate this possible disadvantage, but not entirely. However, the noise made by walls and windows will be stronger than the one heard on the roof. A contractor who tells you that can he permanently reduce the noise from rain falling on the roof will lie to you. But don't asphalt, wood shingles produce noise when the hail falls? Have you ever slept in a tent in the rain? How was it for you?

Metal roofs attract lightning. A house might be struck by lightning, but this happens very rarely. Even if lightning will strike a building,it will not happen due to  the metal roof attraction. We know that lightning is attracted to the highest point, not necessarily by metal. A metal roof can be fitted with a special anti-lightning system. However, if the metal roof is struck by lightning, it will not trigger a fire that is flammable, and the electric charge will be dissipated.

Metal roofs can bend in case of hail. Wrong again, metal roofs can sustain without problems even a man of normal weight. But like any product, there are high quality roofing and roofing of inferior quality, it depends on the budget and on what you want. Serious damage may occur even if you have shingles or wood on your roof. However, it's not advised to climb on the roof and start jumping rope.

A metal roof can be taken by a tornado. Architects and manufacturers say that this is not possible. Metal roofs can withstand even a wind speed of 120 miles per hour, the equivalent of a tornado. A roof made of shingles, wood or asphalt can be quickly destroyed by extreme weather. A metal roof is designed to withstand the worst of nature.

In installing a metal roof, it is required a more expensive workforce. Things are actually the opposite. To install a metal roof,you are using very few tools and it takes much less than installing other types of roofs, and manpower is cheaper.  Taking into account that the metal roof is 50% lighter than the one with shingles, this means that, including transportation, costs are reduced. This type of roof can be installed directly over the old roof, which means no need for disposal and transportation to a  landfill.

A metal roof doesn't have disadvantages,  only requires more attention to its selection and installation. If your system's  metal roof panels will be taken by the wind, this can mean, in the worst case scenario, that there were extremely strong winds that can tear down even the house to the ground, otherwise we are talking about errors in the installation.

Eight metal roofing installation mistakes

Disadvantage of Metal Roofing Denver

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.
