Flat roof repairs: complete service offered for flat roofing!

What are flat roofing repairs?

As time passes and seasons come and go, some parts of your roofing can sustain damages. This does not mean that you have to change it; maintenance and repairs on a flat roof can allow you to preserve it for many years to come.

When we proceed to a repair, we identify all affected components and correct a precise problem like, for example, a tear, a blister or slight sagging. Major roof renovations, on the other hand, occurs when the damages are too great or numerous to consider minor repairs. In that case, roofing will have to be entirely removed and redone.

The quicker we are to proceed to repairs on a flat roof, the less important the damages will be. Repairing a flat roof regularly can prevent having to replace it in the long term.

What types of repairs are possible?

Depending on which part of the roof is damaged, several types of repairs can be done.

Tears and cracks in the membrane must be quickly sealed in order to avoid water infiltration. We will then proceed to waterproofing.

Minor deterioration and small fissures in the membrane can also be repaired.

A clogged or deteriorated drain can also lead to sever water infiltration. Unclogging and cleaning drains can also prevent these damages.

Roof blisters, which can hold air or water, must also be repaired.

Poorly sealed joints are repaired by applying a sealant or by performing a mechanical repair.

Sagging or rot in the roof structure can have different causes. It is still possible to repair these while damages are minor.

Heat islands or ice formations are generally linked to an insolation problem. In the case of a flat roof, it is impossible to repair insolation without removing roofing entirely.

Flat roof repairs: which membrane to use?

Different membranes can be used for roofing and each of them has unique properties.

  • TPO: this single-ply membrane is made of recyclable thermoplastic polyolefin, mostly recognizable by its white color.
  • Elastomer: this double-ply membrane is a compound made of bitumen and modified by polymers.
  • EPDM: this membrane is a synthetic rubber, also recyclable.
  • Asphalt and gravel: this type of membrane is obtained by layering asphalt felt paper and then gravel.

Reparing a flat roof

Repairing a flat roof requires several steps, similar to those of a medical intervention.

Firstly, a diagnostic must be made. Before repairing your flat roofing, make sure you have properly identified the problem by proceeding to a full inspection of the entire surface of the roof.

Then, the area needing repairs must be thoroughly cleaned.

Each intervention will require specific tools. It will be important that proper tools and materials are available and laid out before repairs can begin.

Once everything is in place, roofing repairs can start. Before finishing, repairs should be double checked to ensure everything has been done perfectly.

How to fix waterproofing on a flat roof?

Repairing waterproofing on a roof also requires several steps, which may vary slightly depending on the type of membrane used.

When repairing water infiltration, it is essential to identify the source of the problem. The area in question will then need to be cleaned and dried. A waterproofing product will then be applied in order to seal the area.

What is the ideal waterproofing for a flat roof?

When properly installed and when regular maintenance is done, most membranes offer good waterproofing. However, thermoplastic membranes like the TPO membrane, provide superior waterproofing. Its composition as well as its installation method –robotized induction welding- work to ensure exceptional waterproofing. Moreover, it requires little maintenance and is resistant to severe weather conditions.
