Reinforced bitumen membranes
Bauder's built-up bitumen systems, torch-applied in layers for a tough, repairable roof that suits most domestic and commercial flat roofs.
★★★★★ 5/5 — 700+ happy customers
Anyone can buy a roll of membrane. Bauder only lets approved contractors install its systems under a Bauder guarantee: our roofers are trained on the products, and our work is open to Bauder's own site inspections. For you that means a flat roof built to a written specification, with an independent manufacturer standing behind it for up to 20 years on qualifying systems.

01
Bauder's built-up bitumen systems, torch-applied in layers for a tough, repairable roof that suits most domestic and commercial flat roofs.

02
Bauder Thermoplan and Thermofol single-ply: one welded sheet over insulation, light and fast to lay, ideal for large or lightweight roofs.

03
Seamless systems for inverted roofs, balconies, podiums and the awkward details where a sheet won't do.

04
Bauder insulation boards above the deck, so the build-up meets Building Regulations and the room below stays warm and condensation-free.

05
Bauder living roofs over a root-resistant membrane: sedum blankets and biodiverse build-ups on extensions, garages and commercial buildings.

06
BauderSOLAR and PV-ready build-ups fitted without penetrating the waterproofing, so the panels and the roof are guaranteed together.
01
We come out, get up to the roof where it's safe to, and photograph what we find so you can see the problem for yourself.
02
A clear, itemised price with no obligation. Same-week availability for most repairs, and a rapid response for active leaks.
03
Our own certified roofers do the job — no subcontractors — tidy, on time, and to the standard our guarantee depends on.
04
Every job is backed by our 10-year workmanship guarantee, in writing, from a Salford company that's been on Greater Manchester's roofs for 20 years.

Bauder runs an approved contractor scheme. To be on it, our roofers are trained by Bauder on its systems and our installations can be inspected by Bauder's technical team. Only approved contractors can offer a Bauder system guarantee, which is why the accreditation matters more than the logo.
It depends on the system and the build-up. Qualifying Bauder installations carry a Bauder guarantee covering materials and workmanship, typically 10, 15 or 20 years, and it sits alongside our own 10-year workmanship guarantee.
No. Bauder systems are specified on schools, offices and blocks of flats, but we fit the same bitumen, single-ply and green roof build-ups on house extensions, garages and dormers across Greater Manchester.
Often, yes. We survey the roof first, including core samples where the build-up is unknown. If the deck and insulation are sound, a Bauder overlay avoids a full strip; if they aren't, we'll tell you and quote for a replacement.
Yes. Every job carries our 10-year workmanship guarantee in writing, and Bauder installations carry the Bauder system guarantee on top. We're TrustMark certified and have been on Greater Manchester's roofs for over 20 years.
