Questions And Answers About Standing Seam Metal Roofing

Standing Seam Metal Roofing

"Just What Is Standing Seam Metal Roofing -- How Does It Differ from Other Types of Roofing?"

There are two major aspects of standing seam metal roofing -- one that is largely seen, and the other which is not. What is most visible is the system of interlocking seams that join the metal roofing panels. One of the interesting things about standing seam metal roofing is that the final stage in the joining of these panels together is done right at the construction site.

But the part of your standing seam metal roofing that you probably won't see is a system of metal clips. These serve to attach the metal roofing panels to the underlying roof support structure. These clips allow the metal panels that make up the standing seam metal roofing to freely expand and contract due to the temperature. The other purpose of these concealed clips is that they hold the metal roofing panels in place without being exposed to weather (as nail heads are, for example).

"Can Standing Seam Metal Roofing Be Installed on Top of a Pre-Existing Flat Roof?"

Yes, they certainly can! Here's what your roofer will do: before attaching the new metal roofing panels, they will attach and securely anchor a new sub-framing structure to your old roof. This new roof sub structure will allow your standing seam metal roofing panels to be attached at an angle, so that water and snow can properly drain.

"If I Am Installing Standing Seam Metal Roofing, How Can I Make My Roof More Energy-Efficient?"

Actually, with the right materials installed underneath, your new standing seam metal roofing can become quite energy efficient. For example, your roofer can install fiberglass insulating blankets and blocks of insulated foam over your existing roof structure, before the metal roof panels are installed. This will make your standing seam metal roofing quite energy efficient.

"But Just How Durable Is Standing Seam Metal Roofing? How Long Will It Last?"

Well, although installing in this type of roofing is not cheap, in the long run you will come out ahead, as standing seam metal roofing is very durable -- it is possible to get a good, solid 20-year warranty, in most cases -- and standing seam metal roofing is highly rated for its protection against wind and fire damage.

"I Don't Want to Tear out My Old Roof -- Can Standing Seam Metal Roofing Be Installed over My Existing Roof?"

While some roofing projects may require you to tear down your existing roof covering, you do not need to do that when installing standing seam metal roofing. If a sub floor structure needs to be installed, this can be attached directly onto your existing structure, and the standing seam metal roofing panels can be attached to that -- which means that your new roof can be attached much quicker, and at a much lower cost. As mentioned before, standing seam metal roofing can also be installed over top of flat roofs, through the attachment of this substructure, which will give the new roof its necessary slope for water and snow drainage.
