First Row Of Roof Tiles

Ask this old house general contractor tom silva reveals the best ways to secure shingles to a roof.

First row of roof tiles.

The exposure on the first course of slates may be reduced by dropping the chalk line for the top of the second course of slates in order to increase the headlap on the starter course. Snap a horizontal chalk line over the starting row to use as a guide. Setting out up the roof gauge set the first batten at eaves to allow the tails of the eaves course tiles to overhang the fascia by 40 to 45mm ie. Cut six inches off the length of the first starter shingle nailed on then use the rest of them full size.

Position the first roll of underlayment at one side of the roof perpendicular to the lower edge the eave of the roof. Guidance on the installation of underlay and tile battens is given in section 7. Lay the first row of shingles directly covering the narrow starter row. Just short of the centre of the gutter.

Set out the first second and all the rest of slates on a pitched roof. Next place your two tiles one on top of the other loose onto the battens without anything being fixed. The height distance up the roof of the starter slate must be at least 3 inches greater than the vertical exposure on the first course of slate. Make sure the tile lugs are seated snuggly onto the top edges of the battens.

Tiled roofs first replaced thatched roofs in ancient mesopotamia. See below for a shopping list tools and steps subscr. The top row of tiles at the ridge is also made up of half tiles to give the next row down a double lap. Shifting them in this way will join the ends of the first regular row of shingles placed over the starter shingles.

Underlay and tile battens. Although house models from indus valley civilization show that the houses were flat roofed harappan sites such as alamgirpur dated 2600 2200 bce provide evidence of roof tiles. As you roll out the underlay keep the bottom edge of the material aligned with the edge of the eave but above any metal or synthetic edging that may cover the borders of the eave.
