Waterproofing tile roof - Harvey tile roof in Centurion

Introduction

The roof forms a central part of a property. It is important to have it taken good care of or it will deteriorate and fail. Waterproofing is one of these maintenance tasks of a roof if neglected it will cause huge financial expense and you might not be in the position to do so.

Description

Roof structures deteriorate over time and that is a fact. Bugs, eating wood make a feast out of the timber and it is also a possibility that wood will rot. Entering the roof it was found that the roof structure is damaged.

Problem

Because of the weakening of the timber the roof structure is compromised. Tiles are beginning sag, that means that openings between them started to occur. Water is entering the roof with rain and cause unnecessary damage.

Possible outcome

The roof timber will rot as soon as water enters the roof structure and the forming of mould is unavoidable. When left like this it will lead to the replacement of the roof later. Living in the vicinity of mould, on the other hand, has medical consequences. Both of these scenarios will be costly to rectify.

Suggestion to remedy the situation

The roof needs to be opened by removing the tiles where the roof must be worked on. Attaching timber to the affected roof structure will strengthen it. Waterproof and paint the roof.

Decision with customer/owner

There was an agreement reached whereby the suggested repairs could be carried out.

Waterproofing concrete roof

Introduction

Concrete roofs have a tendency to hold water and puddles form when it does not have a
proper runoff. When not protected with waterproofing water will enter the concrete slab and
mould will form. Newly laid concrete roofs must be waterproofed and the waterproofing
maintained. If not looking after, waterproofing systems will crack and lift off the slab. Now,
water underneath the waterproofing damages the slab and forms mould.     

Description

This concrete roof was left for too long without any proper maintenance. The waterproofing
system is failing as a result of the attack of Uv beams. It is cracked and starts to lift from the
slab leaving a pocket for water to accumulate. Mould is forming and some interior water
damage in the building is apparent. This is as a result of the deterioration of the old
waterproofing system.

Possible outcome

Should the waterproofing not be removed and re-done the reinforcing inside the concrete will
start to corrode. This will weaken the roof structure and water seeping thru will cause internal
ceiling damage. The growth of mould will cause medical issues with occupants even
hospitalised. 

Suggestion

The recommendation in this case, as is in all concrete slab roofs, is to remove the damaged
waterproofing. Then the area should be cleaned of all dust and debris. A new waterproofing
system will only then be able to be installed.  

Decision with customer/owner 

An agreement was struck with the owner and the green light was given to proceed. 

Work commenced

Your step by applying the new waterproofing system is as follows.

Total removal of damaged waterproofing. Removal of dust and debris. The area is cleaned
with a high-power hose. Applying a new bonding agent on top of the concrete slab and the
new waterproofing system as per the manufacturer's specifications. A coat of paint will seal
the waterproofing, protecting it against UV beams.
