Curated entries in Roofing
- Curated 1–4/5Cracked Roof Mortar
Mortar bedding and pointing on tiled roofs cracks over time due to thermal movement and weathering. Cracked mortar at ridge caps, hip ends, and verge flashings allows water to track into the roof cavity, leading to ceiling staining, battens and top-plate decay, and eventual leak damage if left unattended.
- Curated 1–3/5Eave Lining Stains
Staining on eave linings is a visible indicator of past or ongoing water overflow - most commonly from blocked gutters allowing water to back up behind the fascia. We see this in 15.5% of Perth inspection reports, typically as a cosmetic flag that leads back to a maintenance root cause.
- Curated 2–4/5Leaking Gutters
Gutters that leak at joints, end caps, or through rust holes deposit water against fascias, eave linings, and wall cladding rather than routing it to downpipes and stormwater. Persistent wetting creates conducive conditions for fungal decay, borer activity, and termite attack at the roof perimeter - some of the most expensive structural repairs on a Perth home.
- Curated 2–4/5Cracked or Broken Concrete Roof Tiles
Cracked, chipped, or broken concrete roof tiles allowing water ingress to the roof space. Common defect in Perth and Sydney homes with concrete tile roofs, accelerated by thermal cycling and foot traffic during maintenance.
- Curated 2–4/5Deteriorated Ridge Capping Mortar
Crumbling or cracked mortar bedding on ridge capping tiles allowing water entry along the roof ridge line. Extremely common in Perth homes due to intense sun exposure and thermal cycling.
