Signs of roof damage

Identify signs of roof damage for timely repairs and replacements.

Moss, algae or mould

Moss, algae, and other organic growths can retain moisture, which can seep into roofing materials and accelerate deterioration. Over time, this moisture intrusion can lead to rot, decay, and compromised structural integrity, necessitating costly repairs or even premature roof replacement.

Algae, moss or mould growth on your exterior walls is often a telltale sign that there’s an issue with your downspouts or gutters. Cracked or clogged gutters and downspouts can lead to roof leaks, as the water doesn't have a clear path to run off your roof and into the drains. Instead, it can leak out and make your external walls damp, which is the perfect climate for algae or mould growth.

Damp spots

Water stains and damp spots can appear on your interior and exterior walls, so keep an eye out for large ‘puddle’ spots on your ceilings, discolouration on ceilings and walls, or water spots under the roof line outside. Small leaks can cause damp patches in corners that are harder to spot, so keep an eye out for these too.

The absence of overt internal water intrusion does not necesssarily preclude the existence of underlying roofing system compromise.

The presence of algae, moss, or mould on vertical exterior surfaces frequently indicates compromised guttering and downspout functionality. Obstructions or structural failures within these components impede proper rainwater conveyance, leading to water overflow and prolonged saturation of adjacent wall assemblies, creating an environment conducive to biological proliferation and potential latent leakage pathways.

Signs needing attention

The appearance of discoloured or damp areas on interior ceilings and walls, or water staining along exterior soffit lines, strongly suggests active or prior water infiltration.
