Roof Waterproofing Vs Roof Repairs

The big question always asked is, what's the difference between the two?

Roof Waterproofing 

Roof waterproofing as a rule of thumb will relate to the general water tightness of the roof with regards to the flashings and general roof fixtures.

 

Valleys, Undertile membrane, parapet walls, and all the water flow areas that are designed to drive water away from the roof sections to their designated drainage areas, eg. gutters, box gutters.

The above mentioned are generally also sealed with either silicone, mastic or acrylic membrane that is cold roll applied using a block brush, roller or paintbrush.

Roof Repairs

Roof repair leans more to the structural side of why the leaks are happening in the first place. This can range from a roof sag that is due to ailing and failing tile purlins that have compromised the water flow on a tiled roof causing pooling and water capillary leaks in areas that normally are just a part of the roof structure in general. Midsection tile roof no valleys and ridges near but is leaking terribly.

A Roof repair becomes a roof repair when it is a required to strip off the area where the leak is gain access to the troubled roof section and have to replace parts that have failed due to rot, general wear and tear or decay due to bora beetle infestations for example,

 

In most cases storm damage moves and shifts tiles and so forth which at the time is unknown to the homeowner which in time leads to the reason for the rot and pooling, etc.
