When it comes to leaks, low pitch roofs are the most vulnerable.
Roofs between 1 and 4.9 degrees are considered to be low pitch. Only a few types of roofing profiles are made to be installed at such low degrees, including mono clad (Trim Deck) and concealed fix (Klip Lock, Speed Deck, and Top Deck). There are more options than these, but if budget is a priority, the profiles listed above are the best value.
Why we build low pitch roofs really depends on what the building is being used for. Here are a couple of common reasons:
If a flat roof is not properly installed, it will leak — guaranteed. Only work with the best of the best to ensure your low pitch roof stands the test of time.
Here are five critical control measures to use to stop a flat roof leaking.
Low pitch roofs that are installed properly by skilled tradespeople and have a high level of control measures in place will create a fantastic result that no other material can duplicate. Low pitch roofs certainly represent metal roofing at its finest.

When water can enter through a lap, it must be compressively sealed with an appropriate sealant.
The solutions provided are typical only and have been gathered from current and relevant building codes and Australian Standards. The methodologies described aim to achieve water-tightness by mechanical means rather than an over-reliance upon the use of sealants.
Building projects may often require the adaptation or development of ideas and solutions using the principles of sound waterproofing and flashing techniques as described in this fact sheet.
