Homeowners seeking a different roofing solution other than traditional asphalt shingles may be interested in corrugated tin roofing. This type of metal is energy efficient in hot environments, is more affordable than most roofing materials and offers a high level of aesthetic appeal. Knowing about how these roofs are installed can help homeowners work with a local Sugar Land roofing company to determine if this is a good choice for their homes.
Corrugated tin roofing panels come in sheets that measure 42 inches wide by 10 feet long. The roofers will take precise measurements to determine the correct amount of materials to order. Other necessary supplies include galvanized steel roofing screws in a matching color and enough fiberglass roofing felt to cover the rooftop. Ridge caps, metal flashing, gutters and downspouts may also be needed to complete the project.
It is a choice between the property owners and roofers as to whether or not the old roof will be torn off before a new metal roof is put on. In most cases, the homeowners choose to have the old materials removed, as the supporting rafters and trusses may not be able to accommodate the weight of the additional waterproofing membrane and sheets of metal.
The first step of installing a corrugated tin roof is to place the fiberglass roofing felt onto the wooden decking.
Roofers from Houston Restoration Services of Sugar Land TX can answer any question about storm damage or residential roofing.
A staple gun is used to do this, with placement of the staples three inches apart around the perimeter and two feet apart over the interior span of each side of the rooftop. Separate sheets of the felt must overlap by at least six inches.
Next, it is time to place the metal sheets. They should be positioned to overhang the edges of the roof by two inches along the bottom. These sheets should be secured with galvanized steel screws or roofing nails. The nails should only go through the troughs of the sheets and not through the hills. Separate sheets of the tin must overlap by at least two inches. A bead of caulk or sealant can be placed over the head of each nail or screw for additional protection against water and humidity.
The final step is the installation of ridge caps along all of the roof's edges. These caps enhance the roof's ability to resist moisture intrusion. The caps should be screwed into place with the same fasteners as the rest of the roof. A two inch overlap is necessary for each section of ridge capping.
