New installation of Zincalume roof sheeting over a garage area. The roof sheets must be installed with the correct gradient to allow rain water to drain off towards the end where the gutter is located. The roof sheets must be fixed securely with roofing screws to the timbers/steel framework beneath. Flashings will be used to finish off edges to mitigate water ingress along with aesthetic benefits. The way a completed roof looks is just as important as the job it is doing (keeping you dry).
I received a call from a customer who was experiencing water stains on the ceilings inside her property. Upon investigating I found roofing screws had been installed incorrectly. Some fixings had been screwed down far too tightly causing the metal sheet to become damaged. Some had been installed at the wrong angle which pushes the rubber seal out of position. You may think an incorrect angle of a screw is not a problem, but the correct position, fixing pressure and angle make the difference between a water tight roof or a water damaged ceiling.
Moss - Lichen Growth
This image shows the build up of Moss/Lichen to a tiled roof. The customer could hear water dripping inside their ceiling during rain. The Moss/Lichen grows out of control and blocks the small 'gutter channels' of the tile which then stops the rain water flowing down as it should. If the rain water cannot flow quickly down the provided channel in the tile it will overflow into the roof space and damage internal ceilings..
Tile Ridge Capping
Ridge Cap cement does not last forever and does require some maintenance from time to time. The best products on the market right now have a flexible finish to them which allows a very small amount of movement if the ridge tiles were to be put under the force of severe weather or strong winds like which we sometimes experience here in Perth. I find this particular issue the most common when it comes to the conclusion of a roof leak. This image shows the old cement has cracked and fallen away from the tile which is now allowing water to penetrate inside the roof space and onto the ceilings below.
Tile Roof 'Sag'
If your tiled roof is showing signs of 'Sag' then chances are there is a timber or multiple timbers that have become disconnected from their main supporting location. When these sections of roof structure move out of position over time they can cause visual 'waves' in the straight line of the roof tiles. If you do notice this then I would advise you to call in a professional to investigate the issue.
