Metal roofs usually appear as sheets of metal with lines running from the ridge of the roof to the eaves. These lines are actually spots in the roof where two metal roofing panels are joined via a specific joint. These are called standing seams and they do a great deal in flushing storm water.
The seams of metal roofs form canals that help channel storm water from the roof to the ground. They are created using various joints that sit above the surface of a roof, from the simple single lock to the complex trapezoidal seam. Since it doesn’t use the whole roof in flushing runoff, seams make runoff drainage more controlled. The following are some of the common standing seams used in metal roofing.
Overlap joints, single locks, and double locks fall under this category of metal roof seams. As the name implies, it is relatively easy to create simple locks with any kind of metal roof panels in the market. For example, you can do this with an overlap joint by using two joints. One joint should be standing straight while the second joint wraps around the first joint.
Single locks can be done in various ways; but most, if not all, of them usually appear as seams locked at a 90-degree angle. On the other hand, double locks entail that the first joint be shaped like a candy cane as the second joint wraps around the first joint. As the simplest of seams, they are also among the cheapest for roofing contractors and customers.
Clip seams are types of standing seams in which the joints are fitted with a clip or a form of covering. Compared with simple locks, clip seams are typically more secure. Most of the clips in the market are snap-on, meaning these clips can be attached easily on certain joints such as batten and tee seams. Think of clip seams as adding extra padding to the roofing Connecticut homes have.
These seams are hard to make, but they offer outstanding benefits for owners of metal roofing Connecticut. Some examples of complex seams include snap locks, trapezoidal seams, and batten seams. The batten seam is an ideal choice if you want to have a beautiful roof; meanwhile, trapezoidal seams are more concentrated on function than aesthetics.
