Tile Roof Installation: How it’s done
If you wanted to tile your entire roof of your home, what is the process?
Roof tiles are generally made out of clay that have colored concrete form to it, they vary in sizes and shapes. Different tiles are used for different roofs.
Calculating Tiles Required
When you need to find out how many tiles you need it is important to estimate and take measurements of the relevant areas. Noting down the width and height of each individual face of the roof on some paper can help you jot down the important measurements. The measurements can then be added up so that you’re left with a square metre or square footage figure. You can also measure by using the ground as a guidance point or using a tape measure.
Roof laths/Roofing battens
To provide support in stabilising the roof tiles you would use roof laths or roofing battens that are essentially strips of tantalised timber that are pressure treated with a wooden preservative. The roof laths are nailed into roofing joists to provide support for the roof tiles and slates. After this fixings can be made into roof lath.
The most common sizes of roofing lathes are 18mm x 36mm, this is mainly for slating lath or slating batten, or 25mm x 38mm, used on rafter spans of 450mm or below. 30mm x 50mm is mostly used in modern tiles for roofs that are used on rafter spans of 60mm or below.
Spacing Roof Tiles
Unfortunately a lot of builders and roofers get the overall layout of the new roof wrong from the beginning of the process, this can result in a leaking roof and a roof that does not look stable or good.
It is important to be aware that the tiling should start at the bottom of the roof from where the scaffold is at gutter height. When you actually lay the tiles it’s important to spend time planning tile spacing gauge first to see if the tiles fit correctly and neatly with the rest.
When the old roof has been stripped from all areas the rafters or roof trusses will be exposed completely. The rafters should be clear of any loose nails or splinters. A full one width roofing felt is then fitted and securely fit in place using 25mm galvanised clout nails.
When fitting roofing felt or roofing membrane it is important to start at one edge of the roof first and secure with around three nails. After this the roofing membrane would need to be rolled out, keeping it secure and with a slight sag, this will ensure that any water that does come up on the felt that may run between the rafters that will eventually end up in the gutter. If there is too much felt inside the gutter the water flow will become disrupted and dirt will ultimately build up inside the guttering system.
Overall, tile roofs last longer than most roofing systems. Concrete tile roofing is expensive and the pros and cons should be weighed before looking at this roof option. Your current roof may not be able to handle the weight of the tile roof.
