Safety: Working on a roof involves working at height (fifty-fifty on a bungalow), so always utilise scaffolding or other stable platform, never use merely ladders.

Unmarried lap interlocking tiles are possibly the quickest and easiest to lay because one the roof is battened, the tiles simply hook on and overlap each other - most mutual are the physical type simply other materials/shapes are available.

Positioning the battens

The supplier of the tiles should recommend the spacing up the roof between the battens (known as the 'gauge'), this unremarkably varies co-ordinate to the pitch of the roof and the caste of exposure. The 'gauge' is in fact the same equally the 'margin', which is the length of the tile exposed.

The 'guess' quoted by the supplier is the minimum required, you volition need to plant the 'gauge' yous require for your roof - see our folio "Fitting felt and battens" for details of this calculation.

Laying interlocking tiles

At the top terminate of these blazon of tiles there is a single smash pigsty and, on the underside, ii protruding nibs for locating the tiles on the battens. Fitting these tiles is simply a matter of starting at the eaves and hooking the nibs over the wooden battens then laying the next tile forth side and so that it overlaps its neighbour with the nibs hooked on the batten. A point to recollect is that most of these tiles accept the underside of the overlap on the left, and then you need to work right to left.

The tiles going up the roof are usually straight above each other, there is no demand to stagger them as the side joints are automatically sealed by overlaps.

This layout gives a unmarried lap roofing, (i.e. the top role of each tile is covered by only one tile). The overlap will depend upon the slope of the roof - the steeper the slope, the smaller the overlap required.

Cut

Use a mechanical means (such as a disc cutter) for cutting concrete tiles, notwithstanding it can take a scrap of practice to go a neat, clean cut using a disc cutter freehand.

Fixing

Aluminium nails should be used in preference to galvanised nails every bit aluminium will non corrode whereas the galvanise coating will tend to. Alternatively copper or stainless steel nails can be used.

It is non necessary (nor desirable) to boom every single tile - nailing as described here will provide a fully functional roof while allowing individual tiles to be remove later if necessary. Every tile along the eaves, up verges and along the ridge should be nailed, but otherwise only nail every fifth tile horizontally, and every tertiary tile up the roof.

Do non overdrive the nails, there is non fifty-fifty any demand for the smash head to come in contact with the tile - overdriving the nails risk damaging the tile (from the head of the hammer hit the surface) - the tiles tend to be brittle and can easily exist broken.

Outset aligning and nailing the tiles at the correct-hand eaves - work away from this point along and up the roof nailing as appropriate.

Verges

All tiles on a verge should be nailed to the battens are they are exposed, getting a peachy finish to the verge as the sides of the tiles have either the under or over lap; ideally these should be cut off when aligning them with the verge. Alternatively, special verge tiles (which incorporate a downturn) are available in some ranges which simply cover the bring together - plastic verge covers are also bachelor which practise a similar function.

Where ordinary tiles are used to the verge, these should be trimmed (to remove the over or under lap) and bedded onto cement mortar or secured using special clips before nailing - where prune are used, there volition be a need to seal nether the tiles using mortar if barge-boards are non used.

Ridges

The ridge and hips are finished with ridge tiles, ordinarily the same colour equally the roofing tiles. Where ridges meet (such as where a hip ridge meets a master ridge), the ridge tiles should exist trimmed so that the ends of the ridge tiles are parallel when fitted.

The ridge tiles tin be bedded on and jointed with cement mortar (3:1 sand:cement), it frequently looks better if a coloured paint is added to the cement and so that information technology is similar to the ridge tile. (Come across plumbing fixtures ridge tiles)
