The roof of a home is a key element of any building design and one of its most significant structural aspects. Value-conscious house owners seeking long-term roofing solutions that combine aesthetics and performance are increasingly turning toward metal panel roofing. According to much research, metal panel roofing has surged in popularity over the past decade.

Roofs that have metal panels have been shown to withstand all the elements and have a low level of maintenance so their lifetime cost is relatively low. Due to their popularity many manufacturers are developing a wider array of finishes, profiles and colors for the metal panels which will add to the aesthetics of the building. The metal roofing can also save you money in energy costs since the designers have improved the finish which provides a cooling formulation.

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. You will get the maximum benefit from your metal roof only when you are sure that it has the right underlayment, substrate, and finish for your building.

Two basic kinds of metal panel roofing exist, and these are categorized in accordance with the means by which their roofs resist water. The prime factor in determining that is a roof's slant or pitch. Structural roofing has water-resistant paneling and is manufactured for use on roofs with minimal slope. Architectural (or non-structural) roofing is created for use on sharper slopes so that the water is caused to drain off rapidly.

Thermal enlarging and shrinking of structural panels will occur to some extent, which means that the panels and the flashing must be designed to encompass that. In general with a roof, structural panels are capable of fitting between the supports, and are connected by clips to the building structure. A hanging clip arrangement that attaches the panels to the roof allows for the enlarging and shrinking that can occur.

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.
