Condensation and moisture can lead to mold, blackened plywood, smears on joists, tarnished or compacted insulation wool.

Mechanical Inspection

Signs of moisture or condensation may be caused by a mechanical problem in the building, such as poorly connected outlet pipes.

Why does your flat roof leak?

Your flat roof leak can be caused by several factors. It can be a result of ventilation and insulation problems, poorly sealed siding and even snow accumulation. It is important to quickly repair the roof leak no matter the root of the problem. Without immediate intervention, the building may be damaged. However, some good practices can limit water infiltration while waiting for the roofers.

What are the signs of a flat roof leak?

Signs of leaks depend on the type of cladding:

  • For an elastomeric membrane: check for wrinkles, cracked or deteriorated joints and other defects.
  • For an asphalt and gravel coating: common signs of infiltration include bubbles and cracks in the coating.

These clues are more difficult to spot in winter. If in doubt, you should call in specialists to detect and treat a leak early on.
