Can I Overlap Corrugated Tin Roofing?

Corrugated Tin Roofing

• Corrugated tin roofing comes in the form of panels that are intended to fit together to cover a space and keep the elements out. The roofing is also designed as a barrier to help insulate the interior space. The grooves or corrugations in the metal effectively collect and carry water down the slope of the roof, conveying it to the ground or a gutter system.

Uses

• Corrugated tin roofing panels are used as a top layer roof on a dwelling or other enclosed space. The panels often are affixed to the roof already in place. If you're creating a carport or similar open, roofed structure, you can install the corrugated metal roofing on a frame. When used without underlying roof layers, the corrugated tin roofing offers less insulation benefit. Corrugated tin roofing panels can also be used to form exterior walls of a building.

Installation

• Before you begin your project, be sure you have enough panels to cover the roof. Tack down the felt that comes with the roofing panel installation kit, overlapping it according to instructions. Once the felt is installed, nail down the corrugated tin roofing panels, overlapping the edges of each with the next one, and using the number of nails called for in the instructions. Caulk between the corrugated tin roofing panels where they overlap. When the corrugated roofing is completely finished, add ridge caps, which will overlap the upper edges of the panels to complete the water-tight installation.

Tips

• Never create a structure from corrugated tin roofing that touches the ground. Install a base of concrete or stone that will stand up to the elements.

  If you're transporting roofing panels, keep them relatively straight. Allowing them to bend more than 90 degrees can cause permanent damage.
