There are two types of roof restoration, cement tile restoration and terracotta tiles restoration, each requiring different procedures.
Cement tile restoration
Cement tiles tend to become weathered and loose the original roof coatings generally after 20 years and look dirty and worse for wear. So by giving the tiles a high water pressure clean and applying a three coat sealing system they can be restored to look like new, giving your house a refreshed appearance, saving you thousands of dollars by avoiding replacing your old tiles with new and expensive ones and adding value to your prized investment.
A Protech roof restoration consists of:
A high pressure water clean of the entire roof
Removal and replacement of broken tiles
Removal and replacement of rusty valley irons
Remove and replace any timber fascia’s that have rotted
Re bedding and pointing using sand and cement and an acrylic flexible pointing
And a three or four coat sealing system with a great range of traditional and modern colors
We high pressure clean your gutters and surroundings
We remove all rubbish and provide you with spare tiles
Moss tends to grow on Terracotta tiles after a few years, which sometimes, if left to grow uncontrolled, can have an adverse affect on the performance of your tiles due to the fact that on extreme rainy conditions the water courses on the tiles may block and cause leaks. Also, after many years the mortar on the capping and valley areas tends to crack and start to fall away, again, possibly leading to leakages.
A Protech roofing terracotta restoration consists of:
Application of pool chlorine to kill and soften all the moss and fungus on the tiles
Remove and replace broken tiles
Remove and replace rusty valley irons
Remove and replace any timber fascia’s that have rotted
High pressure water clean of the entire roof
High pressure clean the gutters and surroundings
Re-bedding and pointing using sand and cement and an acrylic flexible pointing
We remove all rubbish and provide you with spare tiles.
Should gutters and downpipes be changed before or after a roof restoration?
Gutters and downpipes tend to age and decay in a similar time span to that of your roof mortar and tiles therefore if one is in a position to afford both a roof restoration and a gutter replacement then they should be done at the same time with the gutter being removed and replaced first to avoid any interruption to your brand new tile restoration.
What is re-bedding?
The re-bedding is a mixture of 4:1 sand and cement ratio that holds down and helps the alignment of all the ridge capping and valley mortar. After many years of weather exposure, your bedding can start to break down and therefore no longer holding the capping tiles in place allowing them to slip down and remain out of alignment, possibly allowing water to penetrate to your ceiling. To rectify this problem, all capping must be lifted and all the old mortar removed and re-bedded with a fresh 4:1 ration mix to facilitate the next process which is the flexible pointing.
What is repointing?
The repointing is the final coating of an acrylic pre-colored flexible mixture which has flexible capabilities that can withstand adverse weather conditions and minor structural movements therefore providing extra strong security for all ridge capping and other areas that it may be applied to.
Does a valley need to be replaced because it is showing signs of rust?
Yes. Rust on the surface of any metal is a sign that it could be worse under the tiles in the valley section so, an experienced professional should check it out to make sure it is not leaking or if it needs replacing usually in colorbond or zincalume.
Will high pressure cleaning have an adverse affect on my roof tiles ?
No. The pressure that is used to clean roof tiles is about 3000 to 4000 PSI water and it just removes all the grime, dirt and moss of the tiles leaving a perfectly clean surface for sealants to be applied later.
Does water come into the sealing space whilst the pressure cleaning takes place?
The pressure cleaning has to be undertaken by a well trained professional and 99% of the time, no water penetrates into the ceiling space, however, on certain roofs it may be possible for a few drops to come through some old vents, but very rarely.
Should fall protection be used?
Yes, we at Protech believe that for jobs to be performed at a high standard the tradeperson/s must feel safe and secure therefore, we provide rails or harnesses for their safety.
Is the work guaranteed?
Yes, Protech Roofing has being owned and operated by the same directors and we have provided a rock solid genuine 8 year guarantee for over 20 years.
How many coats have to be applied on cement tile roof restoration?
Under the painters association code, 3 coats is normal practice depending on the wear and general condition of the tiles.
Are jobs supervised?
Yes, we are constantly monitoring and documenting the process from start to finish on all our jobs and a final inspection before handing the final result to our valued customers.
What makes a good long lasting restoration?
A great restoration is archived primarily by performing the preparation stage to perfection, all manufacturers make similar good quality sealants but they must be applied correctly by well trained experienced tradespersons that take pride in their work which is something that Protech Roofing has being doing for over 20 years.
Can we be contacted on an emergency?
Yes, we have a 24 hr service and emergency repairs are done around the clock providing it is safe to do so.
Do valleys need to be cemented when changed?
No, nowadays it has being found that mortar on valleys might accelerate the rusting of the valley irons therefore, they can be left un-cemented. However, a weather foam seal can be applied to stop moisture penetration.
Should I worry about my chipped tiles?
Chipped cement tiles are often caused because they are laid extremely close together. And any structural or climatic changes can cause them to press against each other and therefore chip. It is advisable to have a roof inspection to ascertain whether the chipped tiles are required to be removed and replaced so as to avoid any damage that leaks may cause.
Is Protech Roofing a member of any association?
Yes, we have running a very honest operation for over 20 years and have been registered with the HIA since 1994 and we are registered builders with the Building Commission of Victoria.
