As a Bauder Approved Contractor, one of the most rigorous quality accreditations available in the UK flat roofing industry, we are qualified to specify, install, and maintain the full range of commercial flat roofing systems to manufacturer standard. Connor Hill personally carries out every commercial project from initial survey to final sign-off, with no subcontractors and full accountability throughout.
We work with commercial property clients across Croydon including retail premises, office buildings, light industrial units, schools, church halls, and residential blocks. Whether you need a roof condition survey, a like-for-like repair, or a full commercial re-roof, Hills Roofing Ltd can deliver to the standard your property requires.
Most commercial properties in Croydon are flat-roofed or have significant flat roof areas. Hills Roofing Ltd installs and maintains all major flat roofing systems used in the commercial sector:
As a Bauder Approved Contractor, we can install Bauder's full range of hot melt waterproofing systems and bituminous built-up felt systems, products that come with a manufacturer's guarantee only available through approved contractors. Bauder hot melt systems are among the most durable commercial waterproofing solutions available, with an expected life of 30+ years when installed correctly. They are particularly well suited to large commercial flat roofs with complex drainage details, penetrations, and upstands.
GRP fibreglass roofing is an excellent choice for smaller commercial flat roofs, including retail canopies, extensions, entrance canopies, and single-storey rear structures. A seamless, joint-free membrane with no seams to fail, GRP provides reliable long-term waterproofing with minimal maintenance. We install GRP to BS EN standards with a typical 20-year guarantee on the system.
Single-ply membranes (TPO, EPDM, and PVC-based systems) are widely used on large commercial roof areas where speed of installation and low weight are priorities. Hills Roofing Ltd installs single-ply systems with full welded seams, appropriate insulation specifications, and correctly detailed perimeters, penetrations, and drainage outlets.
For budget-conscious commercial repairs or like-for-like replacements, high-performance torch-on felt systems, including SBS-modified bitumen membranes, remain a cost-effective and durable option. We use reinforced felt systems only, applied over appropriate insulation, and will not install cheap single-layer felt as a long-term solution on commercial property.
If you're purchasing a commercial property, managing a lease renewal, or planning a maintenance programme, a professional roof survey is an essential starting point. Hills Roofing Ltd provides written commercial roof condition reports detailing the current state of the covering, drainage, upstands, and flashings, with photographic evidence and a clear assessment of remaining life expectancy and recommended works. Reports can be provided in formats suitable for use in lease negotiations, planned maintenance schedules, or insurance submissions.
Reactive repairs on commercial flat roofs are almost always more expensive than planned maintenance. Hills Roofing Ltd offers inspection services for commercial clients in Croydon, covering gutter review, joint and upstand inspection, and condition reporting.
Bauder's approval programme requires contractors to meet strict criteria covering installation quality, technical knowledge, insurance levels, and health and safety compliance. As a Bauder Approved Contractor, Hills Roofing Ltd can offer manufacturer-backed guarantees on Bauder systems that are not available through unapproved contractors, an important consideration for commercial clients who need to evidence quality assurance to their insurer, freeholder, or managing agent.
We hold public liability insurance at levels appropriate for commercial work, and all operatives carry CSCS cards and hold relevant NVQ qualifications. Connor Hill attends every survey and project personally; you will not be dealing with an account manager who then dispatches a crew you've never met.
