![]() When you’re looking at standing-seam roof pros and cons, you’ll hear a lot of praise for this roof type. Standing-seam metal roofing is a roofing system where roofing panels are connected at their seams and fastened in place by clips and protected (hidden) screws.Īdvantages Of Standing-Seam Metal Roofing In fact, the rule of thumb is that contractors will need to come out every 5-10 years to replace every single one of the screws on screw-down metal roofs. Several seasons of these expansions and contractions can lead to screws breaking off and shortening the lifespan of these roofs. As these thermal oscillations cause the metal to expand and contract, the corrugated metal roof panels push and pull with significant force against the metal screws that affix them to the frame. ![]() ![]() Second, it is quick and very easy to install as the roof is simply fastened to the frame with screws, which dramatically cuts down on installation time.īecause screw-down metal roofs are fastened to the frame using only screws, these roofs leave very little room for metals to expand and contract in times of heat and cold. It is a relatively straightforward installation process that doesn’t require overly-skilled craftsmen. It is one of the most basic forms of metal roofing you’ll find on the market, and is particularly common over garages and unheated spaces.įirst, screw-down roofing is one of the cheapest metal roofing options you’ll find on the market. Screw-down metal roofs utilizes many individual metal screws to fasten corrugated metal roof panels to a structure. Screw-down metal roofing, also referred to as “exposed fastener” and “through-fastened” roofing, is essentially a corrugated metal roof held together with many exposed screws that hold the roof in place. Here we’ll go into more detail on the pros and cons of each so you can make the right decision for you. The right choice for you will depend on your budget, build-speed requirements and the lifespan you’re looking for out of your roof. Two of the most popular metal roof types are screw down metal roofs and standing seam, or “exposed fastener” metal roofs. If you’ve landed on a metal roof, sifting through the many different metal roofing options can be challenging and overwhelming. For commercial applications, 26 gauge is your best option because it offers more structural stability due to its thickness.As you begin to remodel or build, you’ll probably face the question of what kind of roof you want and whether it needs a ridge vent. For a residential rib metal project, you’ll typically use 29 gauge. Rib metal is going to be your best economical choice for a metal roof. Both the mechanical seamed and snap-lock types have concealed fastener’s which means no exposed screws. The term ‘snap-lock’ means there’s a female and male tab on each panel which ‘snap’ and then ‘lock’ into one another. ‘Snap-lock’ metal roofing is another type of Standing Seam and comes in a variety of different clips and integrated hems depending on panel profile. The panels also create structural stability within the roof. ![]() How the mechanical seamed metal panels differ from a traditional standing seam is that the seams are mechanically crimped to allow zero penetration of elements. Where you would normally only have the choice of a rubber or TPO product on a low pitch, we can install a mechanical seam product to your low slope, keeping it watertight and with all the aesthetic and value of a metal roof. This type of standing seam is your absolute watertight solution for a metal roof. It’s the top choice for residential and commercial metal roofing projects when the pitch of the roof is low. ‘Mechanical Seamed’ is one type of standing seam metal roof. Generally speaking, ‘Standing Seam’ is your thicker, highest-quality metal. Whether you choose to get a standard color or want a custom or specialized patina will also play a role. The type of metal you choose and the gauge of the metal will be the primary determining factors in the cost. In addition to the type or subtype of metal roof you choose, there are different gauges, or thicknesses, to the metal. Within these types of metal roofs are a few different sub-types that serve specific functions for metal roofing needs. There are two basic metal roofing types used in roofing: Standing Seam and Rib Metal.
