Overlaying means applying a new waterproofing membrane over the old roof covering.
The advantages of using this method:
- Save the cost of stripping the old roof.
- Saves the environment as no materials dumped in land fill.
- Less invasive so we can finish quicker, less chance of weather changing whilst undertaking the work.

Frequently Asked Questions Regarding Roof Overlay Systems
Can I overlay and insulate to the new Building Regulations?
Yes, if the roof is sound enough to overlay, then it should be OK to insulate to the new Building Regulation.
Can every roof be overlaid?
Around 85% of roofs can be overlaid.
How do I know if I can overlay my roof?
If the old roof looks good, flat and sound then it can probably be overlaid. If the roof is sagging, spongy to walk on, up and down ‘all over the place’, then probably not.

I’ve been working with Steve Dickinson of London Flat Roofing for almost 10 years and to this day I have not come across anyone with more knowledge on London flat roofs. From leak detection to maintenance, Steve has a wealth of knowledge in all aspects of flat roofing.
Our flat roof was previously installed by cowboy builders. Steve did a fantastic job or un-doing their shoddy work and rectifying all of the issues they had caused. No more leaks and no mess either. The price was fair and they got the job done very quickly.
I came back off holiday to find that the flat roof above my kitchen had been leaking and flooded the house. I called and spoke to Steve who came out the same day and within hours he had identified the leak. The very next day he sent out 2 roofers who fixed the leak. Steve then helped me claim through my insurance policy. Very pleased and grateful for his help.
Steve from London Flat Roofing was very knowledgeable. We had several contractors trying to find the issue with our leaking flat roof prior to getting Steve to look at it. After surveying it with a thermal imaging camera Steve was able to pinpoint the exact location of the leak and fixed it there and then. Very pleased and would definitely recommend to others.

Case Study of Roof Overlay System
This is a Mosque in East London, the original flat roof was a asphalt roof covered with ceramic tiles, over the years it had leaked.
A major overhaul was undertaken and a new felt roof was fitted over the top on a timber frame. After this didn’t solve the leaks the owners decided to seek a more long-term solution. They contacted London Flat Roofing and we surveyed the roof supplied a report and set out several options of how to solve the problem.
One of the solutions we put forwards was the overlaying of the roof using the Gacoroof roofing system. Like normal cost is a big factor and the cost of overlaying a roof is significantly cheaper than the complete renewal.
GacoRoof - Roof Overlay System
It was agreed with the owners of the Mosque that they would strip the roof and deal with the removal of all the rubbish.
London Flat roofing would then attend the property and carry out the application of the Gacoroof roofing system. As an overlay system the Gacoroof roofing system is a perfect example of an overlay system.
Different areas of the roof were prepared for us and given over, we applied the overlay system and completed the roof in sections completing the works within two weeks. The owners of the Mosque now have a roof that will last for probably over 40 years with little or no maintenance at a price that they could afford.
