How to Install Roof Verge Tiles

Verge tiles

Roof verge tilescan be used to good effect as cost efficient feature that will finish the roof flush with gable walls. The end result is that these tiles help in eliminating bargeboards(boards hanging from projected ends of sloping roofs), gable (triangular portion of a wall between the edges of a sloping roof overhangs) as well as verge gutters. The installation of these tiles involves a relatively straightforward procedure. Roof verge tiles are best used on gable roofs as they will prove to be efficient and watertight as well as cost effective. Best of all, they will also be maintenance free solutions that help to finish roofs to good effect.

A verge is a junction of the roof and the gable end of walls and it is mostly at ninety degrees to the eaves and the ridge. When the verge is not at ninety degrees, it is called a raking verge which helps to make rainwater flow away instead of over the verge. Verges are highly exposed to rain which will drive between roof tiles and the wall. High winds can easily uproot the verge tiles, but if installed in the proper manner, this can be avoided. Filling edges with mortar and using nails/clips can help keep these tiles in place.

Step 1: Mechanically Fix the Tiles

Roof verge tiles need to be fixed mechanically with the help of non-corrodible serrated (saw-like) nails measuring 38 x 50 millimeters. The first tile needs to have a 25 millimeter tilt which helps to eliminate overlap and which makes for perfect alignment as well. To achieve desirable results, simply extend the fascia board by 25 millimeters further than the counterbatten. In case fascia boards are not being used, then the tilting batten should be extended.A counterbatten is a vertical strip of wood that is installed on sloping roofs.

Step 2: Placing the Tiles

Next, take the first of the verge tiles and place them so that they adjoin the second rung of tiles. Now, mark the front of the tiles so that they are perfectly lined with eaves course. Cut the tiles to desired length with the help of a special disc. Once this is done, it is then easy to fit the other verge tiles that will easily adjoin the succeeding rungs of tiles above the first level.

Step 3: Create a Junction

It is important to create a junction that is neat as well as secure and for this the topmost verge tile should have the right angle in relation to the pitch of the roof. The topmost verge should be bedded to create a perfect junction. To make the junction waterproof, it is necessary to carry out the ridge DPC as far out as is possible.

Step 4: Positioning of verge Counterbatten

It is important that the verge counterbatten be positioned absolutely flush with the lower part of tiling battens. This will make it possible to fix verge tiles in the best manner possible.

Remember also that the verge tiles should be nailed and/or clipped. Ensure that every verge overhang is equal.

It is important to secure the verge tiles so that they do not get uprooted when subjected to high winds. Using mortar and/or nails/clips can help finish the installation of roof verge tiles and also ensure that the tiles remain fixed in place even if exposed to high velocity winds.
