Of course, having a range of products fit for domestic and commercial properties is not revolutionary.

Where we have something truly different to offer the London flat roofing market is in our refurbishment roofing option.

This type of flat roofing has many advantages, it can be fitted on to the existing structure and so eliminates the need to first remove
the old roof or install new boards.

The roof (as with all flat roofs) provides a guaranteed waterproof finish, and comes with a 20-year guarantee which can also be

The roof over your head matters – Choose an experienced London flat roof installer

At Topseal, we are well aware that the quality of your product is only half the battle, it also has to be installed by experts.

A poor installation can, rightly, lead to criticism online and damage to the reputation not just of the installer but also to the company providing the product. Anyone installing a Topseal flat roof in London or beyond is representing us.

That is why only approved installers can fit our products and to gain that approval it is necessary to undergo a training course and then also have early jobs vetted for quality.

The length of our guarantees, up to 40 years on some products, is a further consideration, we can only offer guarantees that long because there is very little chance any issues will need rectifying. A lengthy guarantee and a flawed product would be a pretty good recipe for going out of business.

If you want to find an approved, local installer please call our customer service team on 0800 831 094. If you have found a potential installer and want to check their accreditation, you can use the installer verification tool available by following this link.


Further questions about your next flat roof?

Undoubtedly, you will have further questions and that’s why we have put together a handy FAQs page, covering issues such as how long does a roof take to install (typically just one day), are the roofs fire retardant (yes, and they have the highest rating for any flat roof system) and can the guarantee be transferred to the new owners if I sell my house (yes, just let us know when you move).

Anyway, we don’t want to spoil that page any more – if you have a query, head this way, we will be more than happy to help
