How to Set a Tin Roof Into The Siding

Tin roofs feature sheet metal, installed with the grooves running down to promote water to drain off the roof. Some older houses have tin roofs, but because of local building codes, the installation of tin roofs now is usually limited to barns, sheds and industrial buildings. Tin roof installation necessitates the use of purlins, which can be flat nailing strips on the roof deck. On roofs where a sloping roof plane and the siding meet, endwall flashing is necessary to prevent escapes. To tie the roof to the siding, then the tin roofing panels must first be installed to within 1/4 inch of this siding.

Add a nail bar beneath the bottom row of veneer that lies above the seam in which the tin roof meets with the siding and then pry upward .

Push on the siding back down along with the nails that hold the siding in place usually remain sticking out a bit. Eliminate them with all the nail bar.

Slide the brief end of a strip of endwall beneath the loosened row of siding and flashing up. Endwall flashing comes in 10-foot lengths and appears like an open letter”L.” The more finish rests on top of the tin roof, covering it about 6 to 8 inches.

Add extra endwall flashing strips if the roof edge is longer than 1 strip. Overlap the strips at least 6 inches and then brush on a thick layer of butyl rubber where the strips match to decrease the probability of leaks. Cut excess flashing that extends using tin snips off.

Nail the siding with 8d nails so the nails run through the siding, procuring the end of this flashing. Utilize the nail holes if at all possible.

Draw a pencil line on the corrugated tin across the edge of the flashing. Here is the filler reference line.

Lift the edge of the endwall flashing to get the corrugated tin beneath. The flashing has a tendency to lay flat across the roof, so you might have to brace it up an inch or two with a scrap of timber.

Install filler strips 1/2 inch above the filler reference line, on the tin roof. Filler strips might be made of timber foam or other substances. On one side, they have the identical configuration as the corrugated roof. On the other side, they’re flat. Installation depends on the kind you decide on, and might entail attaching the strips with silicone caulking or peeling off protective paper and sticking the strips in place.

Apply a bead of silicone caulking into the top edge of the filler strip, then unless it is a press-and-stick form, then reduced the endwall flashing back in to position. The filler strips form a seal between the corrugations on the tin roof and the edge of the flashing.

A neoprene screw every 12 inches across the top rated flat edge of the endwall flashing, in the purlin beneath. On a tin roof, the uppermost purlin lies just beneath this metal’s top edge. To secure the endwall flashing correctly, it is imperative that the screws reach the purlin.
