10 Signs Your Flat Roof Needs Immediate Repair

1. Water stains or dampness on the ceiling

If you notice water marks or dampness on the ceiling or the upper walls, it usually indicates a leak. Although this may seem minor, it can quickly develop into something much more serious.

Icon number 1: Water stains or dampness on the ceiling.
Icon number 2: An active leak during or after rainfall.

2. An active leak during or after rainfall

Typically, a leak will be visible while it rains or a few hours afterward, since water can take some time to make its way through in noticeable amounts.

3. Standing water on the flat roof

Standing water on a roof can be a symptom of a simple clogged drain, but it can also point to something more serious, such as a damaged membrane. If you notice standing water on your roof, do not hesitate to call us for a quick diagnosis.

4. A membrane that is cracked, lifting, or punctured

If you inspect your roof yourself, it is usually quite easy to recognize a membrane that is cracked, lifting, or punctured. These issues are typically resolved with a straightforward repair.

5. Visible blisters or bubbles on the membrane

These swellings are caused by a membrane that has lifted and is trapping air or moisture. It is important to repair the membrane before this problem worsens and more of the membrane lifts.

Icon number 5: Visible blisters or bubbles on the membrane.
Icon number 6: Damaged seams, flashings, or drain perimeters.

Another easy sign to spot is a damaged drain. Besides being visible, this type of problem often results in abnormal water buildup.

7. A musty or mouldy smell indoors

If you notice a musty or mouldy odour without a clear source, it is important to have your roof inspected to ensure there is no water accumulation inside your roofing system.

Water can sometimes build up without causing visible leaks from inside the home.

Icon number 7: A musty or mouldy smell indoors.
Icon number 8: An unusual rise in insulation problems or comfort issues.

8. An unusual rise in insulation problems or comfort

If you experience large temperature fluctuations or other comfort issues related to insulation, it is very possible these are caused by a damaged roof that leads to insulation deficiencies.

9. Repairs that keep coming back in the same area

Do you constantly have to repair your walls or ceilings? It is very likely that an unrepaired leak is continually weakening the affected area.

Icon number 9: Repairs that keep coming back in the same area.
Icon number 10: An aging roof that has not been inspected recently.

Finally, it can sometimes be wise to have your roof inspected and repaired simply because it has not been inspected for several years.

It is better not to wait for the signs that a roof needs repair to appear before taking action.

An inspection can identify a problem before it worsens and save you a lot of trouble.
