Metal Roof Installation Article

While metal roofing can be slick, reflective, and picky to set up, most of metal roofing system jobs aren’t as hard as they might seem. Naturally, metal roof can be applied to any roofing system, however let’s focus on a really simple residential hipped roofing system.

All sides slope toward the ground. Two sides are triangular, while the other 2 sides are trapezoidal.
The basic domestic home with metal roofing will normally have identical pitch or slope on all sides.

Must I Remove The Existing Roofing system?

Metal roof can be set up over existing roof, assuming the structure of the roofing system can sustain the weight. It includes a substantial amount of weight and needs shoring of roofing system supports. Hill Roofing has a lot of experience!
The most efficient ways to set up a metal roofing system is to get rid of the old roofing system, structure new support, and renew.

Begin at the Top

An useful device now comes into play-the measuring tape. Prior to you can buy materials, you need to understand the length of required coverage between eave and ridgepole, the piece of wood that runs from front to back and supports the rafters.

Picture the roofing as a cross section in the shape of a triangle, longest side down. This is called a “truss,” and is alsothe “run distance.”.
Now measure the leg of the triangle which runs from each end of the run range to the ridgepole. This is the “increase distance.” In our case, the increase distance is the very same on both sides.
From here, you can identify the square footage of your roofing, and identify just how much roof material to order.

Adding to the Framework.

Next comes the insulation layer. All roofs have moisture, therefore you want to block it from getting in the sheathing.

The setup process begins at the edge. First, install edging around the whole roof overhang. This is done by nailing to the roofing system structure, and overhanging the edge of the rain gutter system.

Next off, place the metal panels horizontally, square to the edge, and overhanging somewhat. Once in location, protect the panels to the structure with washer-head screws (to shut out water) set a foot apart. It would be an excellent practice to snap a chalk line at each level to position the screws on the frame and create an appealing picture from the ground.

The Layout Process.

Subsequent rows have to overlap by a minimum of an inch. In a specifically moist environment, silicone might be used at the place of overlap; the pressure on the metal sheet will certainly spread out the silicone and produce a seal.

Finally comes the flashing that covers the vertical joints. Where there is a ridge, that flashing can be bent to fit. Like the plates themselves, flashing pieces have to overlap in the direction of all-time low, for water flow.
