We are the specialist for Professional Repair & Maintenance of Roof Waterproofing systems.

What is Roof Waterproofing?

It refers to the waterproofing or water resisting treatment of the roof surface, so as to prevent water passage under hydrostatic pressure. Roof Waterproofing allows the roof system to be resistant against the passage or entry of water through it. To put it another way, roof waterproofing is a process of enveloping on building surfaces with the use of waterproofing membrane and coating to protect structures and objects. 


Why Waterproof Your Roof?

For a building, the roof is an envelope that protects it from harsh weather. Generally, the roof structures and characters vary with the purposes of the building. Balanced against the climatic conditions in the habitat, material for roof structure and roof covering are the elements of it’s shape. In effect, techniques on roofing and repairs flow in chain reactions. Hence, whenever roof waterproofing is done and maintained, buildings escape from climatic changes and restore its health and structure. In other words, so long roof waterproofing is carried out well, it prevents water of any other form of water leakages from entering the living spaces below.

Metal RoofHow to determine Metal Roof Waterproofing is required?

Stopping corrugated metal or clip-lock roof leakages can be difficult. Because metal roof joints, seams, flashing, capping, vents and gutters are areas of weakness, they may allow water ingress with time. Also, roof water leaks can occur in multiple places over the entire surface. As a result, making detection of source difficult. Therefore, if you notice any of the below signs, it may indicate that your metal roof require waterproofing repair or maintenance.


Openings in Penetration Roof Flashing and Capping

Firstly, Metal roofs are prone to expansion and contraction. In effect, metal panels movement creates stress and leads to the breakdown of the roof flashings and capping.  Consequently, allow water penetrations.


Metal Roof Oxidation

Basically, Metal roofs are made from metal sheet that has been coated with a protective surface. Over time, this coating can wear away, leaving the metal panels to oxidize. Subsequently, surface oxidation can lead to structural failure.


Fasteners Backing Out

Under thundery topical weather conditions, overtime fasteners have a tendency to back out of their seated position which may allow water penetrations.


Water Ponding at Metal Roof Gutters

Lastly if you have rain water that remain on a roof for 48 hours, it is considered as “ponding water”. This will eventually breakdown and weaken roof performance attributes. For the most part, ponding water is almost always caused by uneven surfaces, wrong gradient, dirt, debris or root penetrations.
