Standing Seam Metal Roof Installation

Standing Seam Metal Roof Installation

I have a question regarding the installation of a metal roof (preferably a standing seam metal roof) over SIPS or Stress Skin Panels. I live in a post and beam (timber frame) home that is NOT enclosed with traditional stud framing, but utilizes stress skin panels. Is the installation of a metal roof different on this type of construction? Is there anything specific I need to be aware of when evaluating roofing systems? The metal shingle roofing guys I have spoken with have really undermined the quality of a standing seam metal roof. However, I am not sure if their ‘pitch’ is merely a way of ‘selling’ me on their particular roof system, because they do not do standing seam roofs. I’d like some objectivity, but am unsure of where to turn to get accurate information. I would appreciate your insight! Thanking you in advance!!

Standing Seam Metal Roof Installation

Unlike steel and aluminum shingles, standing seam panels should not be installed over the existing asphalt shingles. There are two main reasons; First of all, if you install a standing seam metal roof over asphalt shingles, there will be a so called “telegraphing effect” where shingles can punch horizontal lines in standing seam panels. This in neither aesthetically pleasing nor good for the metal panels. This gets us to the second reason not to install standing seam over shingles. Since most contractors and homeowners are looking to spend as little as possible, they usually choose to install a Steel Standing Seam, which is usually made of Galvalume or G-90 galvanized steel.

Metal roofs are great because they last a long time, are low maintenance, and hold up well in high winds. There are many options when it comes to metal roofing.

I have a asphalt roof that i have installed solar panels to. I have six feet from the panels to the end of the roof, the snow slides down the panels and builds on the roof. I would like to install a metal roof over the asphalt shingles to allow the snow to slide the last six feet off the roof. Do you have a product that will slide under a row of asphalt shingles to attach the metal roof to, so I can have a metal roof the last six feet of the asphalt roof. Hope I explained this in a way you can understand.

For do-it-yourself enthusiasts, for your first installation we recommend installing standing seam on a simple gable roof, with minimum roof penetrations. If you have chimneys, skylights, dormers and/or valleys on your roof, we recommend you leave this task to a seasoned professional installer, because it’s really easy to make costly mistakes when installing metal flashing and other details. – An improperly installed metal flashing could cause premature roof leaks and require expensive repairs down the road.

Before a metal roof can be installed, we have to install the water barrier, which will act as an additional protection underneath the metal roof. Such a water barrier is designed to protect the roof decking from water that occurs from condensation due to temperature differences. Because a metal roof can last well over 35-50 years, it is important to use a good quality, breathable roofing underlayment that will help ensure that your roof decking lasts as long as your metal roof.

Advantages of installing drip edge after the roofing underlayment has been installed, are as follows: You do not waste any precious time during the installation of the drip edge; when and if your roof is open and it rains, you may not have enough time to cover it, that’s where having water and vapor barrier in place really comes handy. Second reason is the safety. When I install underlayment, first I can trim the edges as I please, in case that a hang off portion of the roof is too lengthy. If your drip edge is already in place, and underlayment hangs off of it, trimming it may be rather dangerous, while sitting on the edge of the roof. Lastly – it really does not make much difference in terms of performance. A properly installed metal roof will keep the water out, and the only water on the underlayment will be condensation. If rain water does get onto the underlayment after a metal roof has been installed, then you have bigger problems to worry about!
