Tile roofs don't last for ever and needs maintenance on a regular basis.
It's the purpose of this blog to point out what to look for and how to address problem areas when they occur.
The tiles on a tile roof crack and break easily if not maintained (waterproofed and protected with paint) properly. It is more so with cement tiles, as soon as the protective paint wears down, the roof is vulnerable to the elements. Water is absorbed and the tiles perish. The tiles will fail, water will enter the roof and accumulate as moisture (damp). This is when timber starts to rot and mould grows. Rotting timber is the cause of the roof structure to fail, the roof will collapse. Mould will lead to the occupants falling ill.
Description of the condition of the property
The protective layer of the tiles on this roof is lost and the cement filling between the tiles forming the ridge of a roof is separating.
Problem/situation
When the cement filling on the ridge of a roof separates water will enter the roof. Damp inside the roof help with the rotting of timber and the growth of mould.
Possible outcome
Here we find a classic situation where roof maintenance and waterproofing is left for too long which lead to the cement filling on the ridge to separate. Water will enter the roof and damage will happen. Medical expenses and the replacement of the roof as a consequence will cost the owner a lot.
Suggestion
We have to clean the roof and do roof repairs where necessary. Waterproof and paint with UV resistant paint protects the roof and its occupants.
Work to be done
The roof needs to be cleaned of all dust and debris by means of a high-power hose. Damaged and cracked roof tiles must be replaced. Waterproofing on the roof ridge, flashing and valleys must be done properly. Use quality UV resistant paint to seal the entire roof.

Introduction
Roofs that are not maintained will perish. You will find that tile roofs that are not waterproofed and painted regularly will start to crack and the tiles will break. Tiles will start separating because of insufficient and failing waterproofing. Because of waterproofing failing the roof will start to leak water. Damp will form inside the roof and mould will grow. The occupants will fall ill from the mould and repairs will be expensive.

Maintenance on tile roofs, whether they are hi-pitch or low pitch roofs, are an ongoing task and they need to be taken care of all the time. The sun bakes down on a tile roof and that contribute to the deterioration thereof and after a while leave openings for water to penetrate. Where there is damp accumulating mould will form and will lead to medical issues.
Description
The low pitch tile roof needs repair and some patch up of waterproofing. A few tiles were broken, more of them were cracked and overall tiles started to separate which will lead to water entering the roof.
Problem/situation
This frequently maintained property was dew for a makeover. Waterproofing must be patched up and replaced and a coat of fresh paint will seal it off and it will be good for another 5 years.
Possible outcome
If left alone the roof will perish, mould will grow and cause medical issues. Replacement of the roof and medical expenses are expensive.
Suggestion
It is highly recommended to stick to the maintenance schedule. What needs to be done now is to renew all waterproofing membranes and paint all surfaces.
Work that was done
Before any work can commence the roof needs to be cleaned by a high-pressure hose. If there is any defect not previously seen it will be exposed now. In any case, all dust and debris should be removed from the surface. Any cracked or loose membrane can now be removed and the surfaces are waterproofed again. Waterproofing of valleys, flashing and plumbers vents must be done thoroughly. A fresh layer of quality UV resistant paint will protect the waterproofing and the rest of the roof alike.

A roof forms an important part of a property. Unless well taken care of it will deteriorate and fail. Replacing a roof has huge financial consequences and you might not be in the position to do so.
Description
It's a matter of fact that roof structures deteriorate over time. Wood eating bugs make a feast of the timber and then the rotting of wood is also possible. When the consultant entered the roof there was found that there was quite some damage to the roof structure.
Problem
The roof structure is compromised because of the weakening of the timber. Tiles are beginning to bulge which means that openings between them started to occur. Water will enter the roof and cause unnecessary damage.
Broken timber needs to be replaced
Possible outcome
Water entry to the roof will result in the rotting of the structure and the forming of mould. Left in this situation will lead to the replacement of it in its entirety later on. The forming of mould, on the other hand, has medical consequences. Both these cases will be costly to rectify.
Suggestion to remedy the situation
Open up the roof by removing the tiles where the structure needs to be worked on. Replace or strengthen the roof structure by attaching new timber to the damaged structure. Replace the Harvey tiles and attach them properly. Make sure waterproofing is correctly done and then paint the roof.
Decision with customer/owner
An agreement was reached whereby the suggested repairs could be carried out.
Work undertaken
The roof surface is cleaned of all dust and debris with a high-pressure hose.
The roof tiles are removed to get to the defective roof structure.
The defective truss timber is strengthened and defective roof batten replaced.

A tile roof not sealed off properly will let water in. The consequences are that damp will accumulate inside the roof, mould will grow and timber will rot.
Description
This was a tile roof waterproofing (maintenance and waterproofing) out of the book. The concrete roof tiles were cracked and broke on critical spots letting water to penetrate. Ridge mortar filling between ridge tiles was separating and signs of mould growth showing. No flashing was found where the chimney and roof meats valleys were not sealed with waterproofing. This typical concrete tile roof needed waterproofing badly.
Tile joint not waterproofed
Missing tile and flashing not waterproofed
Problem/situation
The roof lacked proper tile roof waterproofing, In fact no waterproofing except for the prescribed plastic layer underneath tiles was previously applied. This led to water entering the roof which may in addition to dust which gathers in the openings, lead to mold growth and timber rotting.
Broken tiles and joint not waterproofed
Mortar cracking and mold growth
Possible outcome
With water entering the roof damp will form and stay inside for quite some time. Consequently mold will grow as well as the rotting of timber will occur. Needless to say that it will lead to huge financial expenses to rectify. Then there is the medical expenses because of the unhygienic situation.
Suggestion to remedy the situation
Clean roof of all debris and dust with a high power hose. Replace all cracked and damaged tiles. Waterproof hips, valleys, ridges flashing and plungers vents. Paint with a high quality UV resistant paint.
Decision with customer/owner
An agreement with the owner was reached and work could commence.
Work done
First, the tile roof had to be cleaned of all debris and dust particles between tiles. All damage and cracked tiles were removed and replaced with new tiles. The valleys were carefully cut open and flashing as well as plumbers vents cleaned. Then the craftsmen waterproof all hips, valleys, ridges, flashing and plungers vents properly. A fresh coat of high-quality UV resistant paint finished the job.

This tile roof in the south of Pretoria experienced huge damages because the water was seeping in through the tiles causing the wooden structure (rafters, purlins and battens) to rot and therefore fail. It meant that the tiles could not be held up and started to sag.
Description
Water, the biggest cause, after damage from termite and carpenter bees (insect attack), of rotting wood of your roof structure. Here it was not different. Water seeped in between tiles because of the lack of waterproofing material prevented it from happening. The rafters and purlins were totally damaged in some places, so much so that the initial consultation report suggested a total replacement of the structure. Only keeping rafters that were unaffected. Something that the owner could not afford.
Here we have a situation where the origination roofer cut on costs by not installing the prescribed insulation between the roof structure and the tiles by SAFINTA. At best insulation usage under roof sheeting is recognised by roofers as a whole. Now as a result of no insulation used under the roof sheeting, water had the chance to enter the roof and damage the structure.
Possible outcome
The roof structure is compromised because of water damage. At best the roof might withstand the downforce caused by the tiles for another month or two. Then the roof will sag even more, allowing even more water to enter. Now we are compromising ceilings and electrical connections in the attic. What little mould there is now will multiply much fold and cause health issues. the sagging roof, when collapsing can injure or kill whoever was underneath it at the time. The financial consequences can be way more than the replacement of a complete roof.
Suggestion to remedy the situation
Not worth standing the condition of the roof structure the fact that the owner is not in the position to replace the entire roof or only the damaged part it was suggested that it be strengthened. That is, strengthening the damaged parts and leaving the good parts as is. We strongly recommend that waterproofing must be installed in order to prevent water damage in the future for as far as possible.
Tiles unpacked before renovation
The decision of customer/owner
The owner opted to strengthen the roof structure and replacing broken and badly damaged tiles. As far as waterproofing the roof, it was not financially possible.
Work done
Starting with the lifting of the tiles we had to be very careful not to break any because we were on a very tight budget. Moving tiles to another part of the roof we were able to start the strengthening process. This is done by bolting another length of rafter next to the original while purlins and battens are replaced entirely.
After all rotten and damaged wood was either strengthened or replaced the tiles was carefully staged, replacing the damaged ones. Now the roof was waterproofed with a membrane (especially flashing and plumbers vents) and painted.
Result
The roof is now stabilised and there will be no danger of it collapsing on its owner. Tremco is so confident of the workmanship of its workforce it is now guaranteed for a period of five years.
The roof structure was strengthened, all flashing and plumbers vents sealed with membrane and tiles waterproofed with a fresh coat of waterproofing paint. The roof is now strong enough to withstand the weather and has a new aesthetic look of which the owner is very proud of.
All and all, another proudly finished contract by Tremco.
