Refurbishing and Repairing Your Roof

Flat Roof Replacement

Roof Technology advanced products enable your roof to be refurbished whilst leaving you existing cover in place (this is referred to as overlaying)

• Saving money on labour and waste.
• Helping the environment by reducing the amount of waste.
• Reduces the risk of water ingress during installation.

How we do this

Roof Technology use mechanically fixed membranes that will fix into your existing roof deck (once the roof deck has been tested). Metal trims are then fixed to the roof perimeters. The membrane is the welded in place with hot air at 400/500 Degrees, to ensure water tightness.

The Process
First we carry out a ‘Pull Out Test’ to determine the integrity of the roof deck. Screws are put into the roof at various points. A pressure gauge is then used to pull the screw out of the deck. This will tell us if your roof deck is in good enough condition be overlaid. Once the test has been carried out we will then fit temporary felt flashings to your roof to ensure that it is water tight, until we are able to come and lay our roof cover over the existing roof.
