Metal Panel Roofing
A house’s roof is a major part of any construction plan and one of the most important structural aspects. Homeowners who are concerned with getting the most for their money and who are looking for long-term roofing alternatives which are both beautiful and practical are gravitating more and more to metal panel roofing. Copious research has shown that this option has become enormously popular in the last ten years.
Metal roof panels have shown an ability to stand up to the elements, and provide low life-cycle costs and longevity with the least amount of maintenance. Additionally, manufacturers are expanding their metal roofing options in a wide variety of finishes, profiles and colors which enhance building aesthetics. Advances in coatings and finishes have facilitated the formulation of cool metal roofing that adds to the roof’s energy-saving properties and can reduce the costs associated with heating and cooling the building.
When one talks about metal residential roofing, various questions come up throughout the construction planning phase, given the wide variety of products one has to choose from today. It is crucial to comprehend the differences between the various roofing systems. Unless one selects the proper roofing system, under layering, substrate and finish, the roof will not function up to its intended potential.
The two basic types of metal panel roofing are differentiated by their method of water resistance. The pitch of the roof is the most important factor. Structural roofing is useful on roofs with a lower pitch as the panels themselves are water resistant. Non structural roofing, which is also called architectural roofing, can only be used on steeper slopes. On these slopes, water will shed quickly.
Normally, in a structural roof, panels are capable of spanning between structural supports, and are joined by clips to the building structure, The floating clip system that fastens the structural panels to the roof allows for thermal expansion and contraction. Since thermal expansion and contraction influences all materials to some extent, structural panels and flashing must be designed in such a way to accommodate that same expansion.
When structural metal panel roofs are installed, they are usually fitted over a structural metal framing and purlins. It is important to consider the conditions the new roof will be facing when installing. For instance, if the roof will be subject to heavy snow or high winds, solid substrates such as metal decking, plywood, or oriented-stand board combined with ISO board insulation can be laid down first. This will ensure the roof will be sound enough to handle the load.
About the Author: Everyday, more consumers are choosing metal panel roofing technology. The metal roof panel has been proven to withstand all sort of weather, last a long time, and require very little maintenance. Technological developments in coatings and finishes have made it possible to develop cool metal roofing which provides greater economy by decreasing energy use and therefore lowers the money we spend to cool or heat our buildings. There are many questions that come up when you are talking about metal residential roofing. There are numerous choices available, so it is very important that you know about the difference between roofing systems.
