Most of all the insulation process for metal roofing is a breeze. There are many different variations of insulation from product to product; however, insulation is very similar. It begins with a strip that is installed along the bottom eave edge of the roof which allows the first course of shingles to be actively locked into place. This will help uplift resistance as an overall roof security.  Then, an additional perimeter trim is installed on the roof before installation.  Included in the parameter trims are gable end trims, valley pans, roof to wall flashings, and even base trims around protrusions such as chimneys and skylights.

Roof panels usually can be installed in a series of modular panels that will interlock on all sides. You can find fasteners along the uphill edges of the panels which will then be concealed by successive courses of the roofing panels. It’s important to do this properly as it will help to avoid exposed fasteners, as this can obstruct the entire aesthetics of the metal roofing system. 


If you’re looking for an energy efficient option, horizontal battens can increase the energy efficiency of the roof by allowing active ventilation. Exposed fasteners are usually hidden in the butt edges of the roofing panels so when installation occurs this must be considered.  An active fastening combined with an interlocking nature creates roof systems that will pass wind uplift requirements and is met by Texas Department of Insurance and others.

Another great benefit to the metal roofing product is that it is self-cleaning and is a great choice for roofs being exposed to debris, tree leaves, pine needles, ice and snow. Some of the other roofing products also include water-carrying methods to create weathertight roofing system if water is an issue for you. Keep in mind that you need a minimum 3:12 roof pitch when considering horizontal interlocks and thick buttlines.  

Vertical seam metal roofing systems are becoming popular and with their great benefits they will be a high demand product well into the future. If you’re considering shingle, shake, slate or tile look products these are also high in demand.  Make sure you do your research and ask the manufacture to provide installation and specification details so you know exactly what is to be expected. The manufacture should also be able to provide a list of names of experienced installers who will install the roof properly and functionally.  This will ensure a successful metal roofing system.
