A metal roof is a durable, long-lasting, and attractive roofing option for your home. You may not realize you have choices when it comes to the style of metal roof you can put on your house. A popular option for residential roofs is snap-lock metal roofing. Here's a look at the benefits of this type of roofing and how a snap-lock metal roofing contractor installs the roofing panels.
Benefits Of Snap-Lock Metal Roofing
Snap-lock is a form of standing seam metal roofing. This roofing has an attractive appearance and fasteners that are hidden. A different type of metal roofing is exposed fastener roofing that has screws exposed to the sun and rain. Exposed fastener roofing is screwed to the deck and the screw tops are visible, so the appearance isn't as attractive. Also, exposed screws make the roofing much more vulnerable to roof leaks.
One of the important benefits of snap-lock roofing is the lower risk of a roof leak due to the hidden screws and standing seams that snap to each other. This roofing can also be custom-made to the exact length needed, and it comes in several colors.
Installation Steps For Snap-Lock Metal Roofing
The first step in the installation process is to remove all of the old roofing so the wood deck can be examined for water damage and repaired if needed. Then, a waterproof underlayment is put on the deck. Once that's done, the roof is ready to start installing the metal panels.
The snap-lock metal roofing contractor may extrude the panels on the spot to the exact length needed for your roof. As the panels are extruded, the sides are folded so they can lock together once they're on the roof. The panels are attached to the roof deck with clips.
Clips slide on the side of the panel and are screwed to the deck. When the next panel is put on, one of the legs fits over the leg of the panel already installed and snaps in place. When this happens, the screw and clip are covered and protected from rain.
This installation process repeats until the entire roof is covered in snap-lock panels. This design allows water to shed easily without pooling and getting under the panels. Since the legs bend and snap together, it's very difficult for rain to get between the panels, so the risk of a roof leak is low and repairs to the roof should be minimal over the life of the panels.
This type of roofing is usually made with durable steel, so it's tough against storms, but you'll want a contractor to check it periodically for damage so the damage can be repaired early if it ever happens.
