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. Firstly get two of your roof tiles and either two full battens or two offcuts of batten and place them onto the roof one above the other.

Make sure the tile lugs are seated snuggly onto the top edges of the battens. 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. Position the first roll of underlayment at one side of the roof perpendicular to the lower edge the eave of the roof.

Cut six inches off the length of the first starter shingle nailed on then use the rest of them full size. Just short of the centre of the gutter. 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. See below for a shopping list tools and steps subscr.

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. Underlay and tile battens. Guidance on the installation of underlay and tile battens is given in section 7. Tiled roofs first replaced thatched roofs in ancient mesopotamia.

Lay the first row of shingles directly covering the narrow starter row. Set out the first second and all the rest of slates on a pitched roof. The lowest row of tiles at the fascia board is made up of shorter tiles to provide the double lap for the first row of full ones the lower edges of these short tiles and the first row of full tiles should be the same.
