Water Infiltration Through a Flat Roof

Water infiltration occurs for a number of reasons. It can be the result of a ventilation or insulation deficiency, improper sealing of the roof sheathing, and even an accumulation of snow. Whatever the problem, the key is to quickly repair the leaky roof. Without immediate intervention, the building may sustain damages. Consequently, as soon as you notice the early signs of water leakage, please contact roofers trained for such work. Our specialist roofers have both the experience and the equipment needed to effectively address water infiltration and regain the integrity of your property.

Report water infiltration

Interior Inspection

Water infiltration can be the cause of ceiling stains, peeling paint, warped gypsum, cracks in the ceiling, or water on the floor.

Roof Inspection

The signs vary depending on the type of sheathing. In general, you will notice a deterioration in the quality of the roof covering, such as cracks or defects.

Attic Inspection

Condensation and moisture can lead to mould, stained plywood, marks on the joists, and tarnished or compacted insulation.

Mechanical Inspection

Signs of moisture or condensation may come from a mechanical problem with the building, such as improperly connected exhaust vents.

Water Infiltration Solutions

When water leakage occurs, our technical consultants inspect both the roof and the interior of the building. They have the knowledge to determine exactly why a roof is leaking. As a result, they can propose the best solution to protect the building from water infiltration. Key interventions to address a leaking roof are:

  • Snow and ice removal from the roof.
  • Plug the leaky roof.
  • Change the roof sheathing.
  • Optimize the ventilation and insulation.
  • Improve the building's waterproofing.
  • Repair the areas affected.
  • Optimize the structure and decking.
  • Ensure the effectiveness of the drainage system.

Preventing Water Seepage Through a Flat Roof

Prevention is the best way to protect your investment. It is recommended that you carry out the necessary inspections every three months. Please pay close attention to the attic, since water may have seeped in without affecting other parts of the house. If that is the case, the damage may have affected the insulation, materials, and the roof covering. The more water spreads throughout the building, the greater will be both the damage and the costs of repair. Those consequences justify preventive inspections of your building.

The signs of water infiltration vary depending on the type of cladding. In the case of elastomeric membrane, there will be folds, cracked or damaged seals, and other irregularities. If your flat roof is covered with asphalt and gravel, signs of water infiltration are generally bubbles and cracks in the covering. In winter, these signs are harder to spot. So it is advisable to contact our specialist roofers who can detect a major or minor water intrusion.
