Some tips to determine whether roofing or repairs are needed

Gather your binoculars or climb up the ladder to inspect your roof for any signs of damage. Inspect the roof from a distance using binoculars. Some tell tale signs that indicate that it is indeed time for repairs and slate roofing are:

  1. Moisture:
  • Any new sign of moisture in the attic or rafter is an indication that you need immediate repair.
  • Moisture also means that the slate has absorbed a lot of moisture in the long run and is decayed, and needs full replacement in majority of cases.
  • Leaks after heavy rains:
  • It also indicates that tiles are damaged and need immediate replacement or repair.
  • Manually inspect the roof entirely to see the source of leakage or broken tiles and get them replaced immediately.


2. Fallen tiles:

  • If the fallen tiles resonate sound when you tap it with your knuckle, it is an indication that it can survive a few more seasons and you need to only replace the nails.
  • If the tile did not resonate to the tap and produced a dull sound, it is time to give a call to the professional inspection team


3. Percentage of fallen tiles per section of the roof:

  • Any section with 20% or more fallen tiles needs replacement.
  • If there are fallen tiles randomly across the entire roof, it might indicate extensive damage that needs complete roof replacement.


4. Rusting of the slates:

  • The rust-colour change in the slates is not a good sign.
  • It indicates that the slates are delaminated, and too thin and fragile to be retained.


5. Moss on slates:

  • When moss or lichens cover the tiles, the retain moisture and can penetrate to cause extensive damage.
  • Heavy moss growth can completely lift and separate the slates from the roof.
  • It is an indication that you need a thorough chemical treatment and even full replacement in case of extensive damage.

It is not economical to patch a roof where 25% or more tiles are delaminated, damaged, or leaking. It will be a cost-effective decision to opt for full replacement.

Let an expert do the roof inspection as they will be able to determine the exact slate roofing product that was used in the installation, the age of the roof, and also the extent of repairs and replacement needed. A professional will even point out minor need for repairs that your eyes would have easily missed.
