Standing Seam Roofing Guide
The costs of standing seam roofing can vary based upon the local costs of labor and supplies as well as the types of panels that are used. For nine hours of labor, the cost to install standing seam roofing generally ranges from $496 to $608. This fluctuation partially results from seasonal wage rate variations as well as the actual job location.
Minimum cost of standing seam roof material per 100 square feet: $699
Maximum cost of standing seam roof material per 100 square feet: $884
In regards to supplies, consumers can expect to pay approximately $107 to $124 for 100 square feet of installation. These supply costs include items required for preparation, bonding, fabrication and surface patching as well as a rental allowance for professional fabrication and installation tools. As with most construction installation costs, there may be a significant cost variance due to complex roofing configurations. Also, higher priced standing seam roofing materials might include additional features such as top quality underlayment, increased damage resistance, thicker roofing material and extended warranty terms.
Standing seam roofing is the most common style and form of metal roofing systems. It is an extremely effective, durable and long lasting style of roof that is comprised of metal panels that run from the top of the roof to the eaves. Each of the panels contains a high lip or rip up each side that overlaps and fits together. As a result, this conceals the fasteners and creates raised seams from top to bottom. There are actually four types of standing seam roofing panels, which are mechanically seamed hydrostatic panels, symmetrical mechanically seamed panels, one piece snap-lock panels and two piece snap-lock panels.
Types of Standing Seam Roofing Panels
Hydrostatic panels, also known as structural standing seam metal roofing panels, require a mechanical seaming tool to engage two standing seam panels. These panels provide a particularly excellent wind uplift resistance, and the panels can either be tapered or curved.
Symmetrical mechanically seamed panels are the most innovative and recent option of standing seam roofing panels. This option integrates the weather resistant advantages of the mechanical seam with the replacement choices of the two piece snap-lock panel. The Symmetrical Mechanically Seamed Panels can be installed utilizing fixed clips that permit thermal movement and can be curved or tapered. As this system eliminates the various disadvantages associated with other metal roof standing seam options, this is likely the best option for most roof designs.
One piece snap-lock panels involve two standing seam roofing panels that snap together and are most applicable for decked applications. This system is less desirable in areas of high wind as more attachment points and clips are needed to meet uplift pressure points. As a result, the demand for this particular type of standing seam roofing panels has been declining significantly over recent years.
Two piece snap-lock panels require a batten or cap that brings two panels together by snapping down onto a butterfly clip. These panels are best suited for roofs that feature valleys as they can be installed in multiple directions. The demand for these types of panels has also been decreasing over the years since they offer very few advantages from a structural standpoint.
There are many advantages to standing seam roofing as well as a few disadvantages associated with this type of roofing system.
Advantages and Disadvantages of Standing Seam Roofing
Metal is an extremely tough material that can withstand most weather conditions and debris, and it is both fire and wind resistant. Although it can still be penetrated by heavy falling tree limbs or dented by severe hail, the metal in standing seam roofing is much more secure than other roofing materials.
A major advantage is that the seams are raised above the level of the roofing panel, which strengthens the roof and significantly reduces the potential for moisture to enter through the roof structure. There are no horizontal seams and a low number of seams on the roof overall as the metal panels run unobstructed from the top of the roof to the bottom.
Standing seam roofing is lightweight, which reduces load-bearing structural costs. Metal roofs can sometimes be installed directly over the top of an existing roof, which eliminates the cost and waste of disposal. Standing seam roofing systems are energy efficient and block heat transfer, which reduces home energy costs (particularly in locations with hot climates).
The metal in standing seam roofing can be painted in any color to provide a nice contrast to the rest of the structure. This can also be particularly useful in warmer climates where the metal can be painted in a lighter color to reduce solar heating. Standing seam roofing is attractive and ideal for barn-style, modern and traditional homes. Metal roofing can be created to resemble Victorian metal tiles, clay tiles, shingles, or wood shakes to match and complement the design of any home. The majority of metal roofing contains a significant amount of recycled materials. In addition, it is totally recyclable at the end of its useful life.
The cost of standing seam roofing can be considered a disadvantage since metal is a moderately expensive roofing material (the cost lays above conventional shingles but below copper or slate). However, the cost is offset by the long lifespan of metal as it can last a minimum of three times longer than composite shingles. In addition, most standing seam roofing systems feature a warranty lasting at least 30 years.
There are relatively few contractors who install metal roofing as opposed to conventional roofs. Therefore, the consumer may have difficulty in finding a good roofer (and the overall project cost might be higher due to less local competition). The majority of standing seam roof systems does not work well on roofs with flatter pitches.
