5 Hidden Signs of Roof Damage
Don't wait for a leak to tell you there's a problem. Check your roof for these 5 critical warning signs before they turn into costly repairs.
1. Crumbling or Missing Mortar (Pointing)
The mortar that holds your ridge caps together degrades over time due to sun and rain. If you see cracks, gaps, or chunks missing, water is likely already getting underneath. This is the most common cause of leaks in Melbourne homes.
2. Cracked, Slipped, or Broken Tiles
Even a hairline crack in a single concrete tile can let significant amounts of water into your roof cavity during heavy rain. Look for tiles that are misaligned or visibly damaged.
3. Heavy Moss and Lichen Growth
Moss isn't just an eyesore — it acts like a sponge, holding moisture against your tiles and slowly eating away at the protective surface. If left untreated, your tiles will become porous and brittle.
4. Water Stains on Interior Ceilings
If you notice brown or yellow rings on your ceiling plaster, the damage has already breached your roof cavity. This requires immediate attention before structural rot or mold sets in.
5. Granules or Sand in the Gutters
When you clean your gutters, look for a heavy buildup of sandy material. This means the protective coating on your concrete tiles has completely worn away, leaving them exposed to the elements.
