FAQs & Case Studies

Below are some of the problems and issues we have encountered (and solved) in the past.

Can you repair my roof without damaging the one next door?

We were contacted recently by a distraught customer whose garage flat roof was leaking. Her garage was adjoined to next door’s, in effect creating a 'double garage'. She was having real problems getting a reliable roofing company to come out and repair her garage roof, without damaging her neighbour's.
With our liquid membrane system, this proved no problem whatsoever... as the results show below.

Lead Replacement:


Lead lasts a long time but, when it does perish, repairs can be so expensive that they frequently become 'cost prohibitive' to replace. Our reinforced liquid membrane system is not only the same colour as lead - it is also sometimes described as 'liquid lead', as it shares many of the advantages of lead, but is pourable, seamless and joinless, and much cheaper. We retain as much of your roof and leadwork as possible, something our system allows for more easily than almost any other roofing system.

No Access Problems:


We may be the only roofing company not worried about access.
RM Polymers received a call from a client concerned about access to the flat roof at the rear of his house. He lived in a mid-terrace house, with no way of getting to his flat roof except by walking through the house. He had contacted many companies, only to be told that due to the bulky nature of some of the materials they used, not one of them was able to guarantee a 'safe passage' through the house without damaging paintwork, etc.
As the materials we use are far more compact, we were able to carry all our equipment through the house easily, after placing dust covers, ensuring absolutely no damage was caused. We accessed the roof via the back and completed the job within the day.
The client was amazed at both the efficiency and high quality of our work.

Masonry Waterproofing:


Sheet rain was saturating this west-facing wall. The leadwork, slates, fitting of the Velux window, and the lower gutter were all being blamed for the water ingress. The stone wall, as you can see from the image, has no stepped lead trays in its construction.
The client had re-pointed the stone work, as you can see from the different shading of the mortar in the picture. But the amount of rainwater hitting this westerly elevation wall on the seafront meant that the pointing and stonework was unable to deflect the amount of rain being experienced.
The wall was sealed quickly, easily, and successfully using Coelans, a fuss-free solution with a life expectancy of 10 years.


Can you water proof my balcony?

Of course! In fact, lining balconies and roof terraces are two very popular requests, and the liquid membrane roofing system is perfect for the job.
