How To Assess Mould And Mildew Growth In Roof Trusses?
In the previous blog, the main causes of mould and mildew growth in roof trusses were explored. In this blog, the telltale signs of mould and mildew in engineered roof trusses and the best ways to assess them are addressed.
Telltale Signs Of Mould Growth In Roof Trusses
Visual Discolouration And Powdery Texture
One of the best indicators of mould and mildew growth in roof trusses is evident visual discolouration. How does it look visually? It can surface dark or black growths on the roof truss, clearly indicating the presence of mould. Another good indicator is a fuzzy or powdery texture on the surface of the roof truss. If not evident visually, it can be assessed easily by touching the surface of the truss.
Presence Of Musty Odour
While the first sign is visual, the second is olfactory in nature. The presence of a musty odour in the attic where the engineered roof truss is placed is a clear indicator of mould and mildew growth. This smell is even more pronounced if the attic has poor ventilation.
How To Assess Mould And Mildew Growth?
Apart from visual inspection and smell detection, there are some more advanced ways to assess the growth of these unwanted elements in the roof truss, so it can be addressed on time. These include:
Detecting Moisture: Before it becomes evident visually, mould and mildew can be nipped in the bud by detecting moisture. Moisture meters and thermal imaging systems are excellent ways to assess the areas of the roof truss that are most susceptible to moisture accumulation.
Assessing the Structural Integrity Of The Roof Truss: The next best way to assess the presence of these elements in a roof truss is a thorough check on structural integrity. Check for sagging or bowing of the truss or the presence of cracks. These can aptly indicate the weakening structural integrity of the roof truss, requiring bolstering or replacement.
Collecting Samples and Testing: If mould and mildew are already present, the best course of action is to collect their samples and send them for lab testing. In this way, the exact strain can be identified, and its associated health risks can be determined. It can also help in finding the right solution to remove them effectively.
The next blog will cover best practices on removing these unwanted elements and reinforcing the roof truss.
