What Causes Flat Roof Leaks?

There are numerous causes of flat roof leaks. The frequent sources include the following;

  1. Cracks and Splits; Caused substantially by aging, the material isn't capable of duly expanding and contracting, backfiring in the material splitting as the expansion is higher than anticipated.
  2. Joins and Overlaps; A familiar cause for joins and overlaps leaking comes from the lapping not being very good. This causes the water then tracks in between the two layers. However, it's frequent for this to be an area of concern, if the product has been fire-welded simultaneously. The join can part due to not being welded sufficiently. Still, the material can split due to being watered down from over-heating the join and damaging/ melting the material.
  3. Around outlets Roof- lights; A common cause here's that the flange around an outlet is either not substantial enough and or is ill befitting to the pipe or outlet. It could also be due to not being clammed to the flat roof material and or incorrect installation.
  4. Lead Flashing or where the felt itself is flashed into the wall; It's well tactical to check along the joint where the roof material is erected (flashed) into the touching wall. It's usual for the installation to not be profound enough causing it to pop out, leaving a gap for the water to fluently enter the structure.
  5. Screw/Bolt holes; There should be no bolt holes and screws passing through any flat roof stuff, but due to the fitting of air exertion units, rails, etc the silicones harden causing them to fail in dilating and contracting satisfactorily.
  6. Alteration in angles; Frequent when lining gutters, the covering of asbestos sheets or where the border of the flat roof meets with a perpendicular wall, it's significant to check these areas as the crest or curve puts varying stresses on the roof material. The 90 ⁰ angle is always an area to be checked instead as cracking frequently occurs along this angle.
  7. Glazing Bars; Old glazing was substantially installed and clammed with the use of putty which over some time not only becomes crisp but also naturally loses its tenacious strength. Also, flat roof leaks can be caused due to rotting/old timber.
  8. Ridge Caps/Missing Foam Infills; Foam infills utilized to fill the gap, specifically on corrugated roofing breaks down (mainly by UV declination) over the years and fall out. Inversely it can be pecked removed by birds, and ingested by insects and rodents which also means that the remainder unavoidably also falls out.
