How to Install Tile Effect Roof Sheets?

Tile Effect sheeting can only be laid left to right, because it is only tiled one way. Make sure the overlapping edge is at the start of the process ready for the next sheet to overlap the underlapped side (as shown). We recommend laying away from the common prevailing wind to help prevent wind whistling and water capillary but on this profile sometimes this cannot be helped. Please note the overlapping edge is always the unfinished castle overlapping the finished castle.

Fixing screws are highly recommended to screw between the strengthening ribs in the valley of the sheet (as shown). Usually fixed in the 1st, 3rd and 5th trough (left, middle, right) to have a symmetrical appearance and a strong holding into the purlins. Fix in every purlin if possible but every two is adequate on short purlin spacings.

We recommend using a maximum purlin spacing of either 300mm or 600mm for 0.5mm only, due to the tile centres being at 300mm. Having an irregular purlin centre may result in a tile crimp sitting directly onto the purlin creating an uneven lay in the finished roof.

Stitching the sheeting overlaps are very important (as shown). Stitching the overlapping castle every 300mm (each tile) is adequate but if you can fix at 600mm (every 2 tiles) if necessary. This will help prevent water capillary seeping underneath the sheet. Applying lap tape isn’t recommended with this profile but silicone can be used if you require.

Ridge and Barge flashings are always fitted after the sheeting. Again, using the stitching screw to fix through the flashing into the castle of the sheeting. Once this process is complete then fitting foam infills between the ridge end and eaves is recommended to help prevent birds or vermin trying to enter the structure, and also preventing wind pushing anything through during poor weather conditions. (Please note we DO NOT recommend using foam infills if you have our Drip stop membrane system installed to your sheeting due to the roof requiring ventilation for the Drip stop to work at its optimum).

If the sheeting or flashings need cutting / trimming, we recommend using a ‘Nibbler Attachment’ due to the clean precision cut it can offer. Angle grinders are commonly used but this will not offer a clean cut. A Nibbler will be the most sufficient tool for this.
