Tile Installation 3

Finishing the First Row of Tiles

From the first chalk line, mark off successive 44-inch spaces along the eave. Do the same at the ridge. This distance allows for a 1-corrugation side lap.
Snap chalk lines between the eave and ridge marks for tile alignment.
Now lap the second tile one corrugation over the first, fastening it as you did the first one (See Fig. 19).
Continue fastening tiles until you are five tiles from the end of the Cave row. Lay the last five into position to see if you have a tile valley flush with the rake. (See Fig. 20.) If you do not have a valley flush with the rake, shift all five unnailed tiles left or right until you have a valley flush with the rake. Fasten these tiles in place with closure strips beneath eave edge.

Installing the Second Row

Installing the second row

Snap a chalk line (or pull a string line) 14" from the lower edge of the first row of tiles (See Fig. 17).
Begin the second and all even-numbered rows with a tile cut along a valley with a knife so that this tile has only six crowns. (See Fig. 21.) Doing this staggers side-laps from row to row so there are never four tiles thick at any point.
Place this six-corrugation tile flush with the rake edge, butting the chalk line snapped on the first row. This will give you an even exposure along the roof.
Nail this tile in place and install the remainder of the second row using full tiles.
Continue installing rows on both sides of roof until reaching the ridge. (See Fig. 21.)

NOTE: With roof valley, always flash the valley first, then work from the rake edge to the valley.
