A commercial roof is one of those parts of a building that tends to get ignored until something goes wrong. At that point, business owners are suddenly making urgent decisions about contractors, materials, and costs - often without much background knowledge to draw on. This page is intended to help you make a better-informed choice before that situation arises, or to guide you through it if it already has.
We carry out commercial roofing across Mildenhall and the wider area, working from our base in Bury St Edmunds. The work spans flat roof systems including EPDM rubber membranes and built-up felt, profiled metal roofing for industrial and warehouse buildings, roofing repairs, roofing carpentry, and rainwater systems including fascias, soffits, and guttering.
Commercial roofing differs from domestic work in scale, access requirements, and the consequences of getting things wrong. A leaking office roof might mean sodden ceiling tiles; a leaking warehouse roof can mean damaged stock, health and safety concerns, and a building that is unfit for occupation until the problem is fixed.
Flat roofs on commercial buildings need correctly engineered drainage falls, properly detailed upstands around every wall and parapet, and flashings around every pipe, vent, and roof light. Single-ply EPDM membranes are now widely used on commercial flat roofs because they handle large uninterrupted spans well and deal with thermal expansion and contraction better than older bitumen systems. Built-up felt systems remain practical for many applications and are still a sound choice when specified and installed correctly.
Profiled metal roofing is the standard solution for industrial and agricultural buildings. Steel or aluminium sheeting, fixed to a purlin structure, provides a weathertight and relatively low-maintenance surface across wide spans. Roofing carpentry - replacing decking, joists, or timber upstand framing - is regularly needed as part of flat roof replacements where the existing structure has deteriorated.
Choosing the wrong contractor for a commercial roofing job is an expensive mistake that is difficult to undo. Unlike a domestic roof, the scale of the work means problems are harder to fix and more costly when they recur. Below is a practical framework for evaluating contractors before you sign anything.
A contractor who handles domestic pitched roofs day-to-day is not automatically a poor choice for commercial work, but you should ask specifically about their experience with the type of roof you have. If your building has a large EPDM flat roof, ask whether they have installed that system before and on what scale. If you have a profiled metal roof on an industrial unit, ask about comparable projects. Photographs of completed work are a reasonable thing to ask for.
You are not looking for a portfolio of hundreds of jobs - you are looking for evidence that the contractor understands the specific demands of your roof type, and that they have dealt with similar detailing challenges before.
The following questions should be answered clearly in writing, either in the quote itself or in a separate specification document. If a contractor cannot or will not answer them, that tells you something important.
A quote with no specification detail attached - just a single figure for the whole job - is a sign that either the contractor has not thought it through carefully, or that they intend to make decisions about materials on site that should have been agreed upfront. Either way, it is a risk.
Unusually low quotes deserve scrutiny rather than celebration. A price significantly below others is usually explained by a thinner membrane specification, cutting corners on drainage detailing, or not allowing for the possibility of substrate repairs. Ask the contractor to explain why their price is lower. A good contractor will be able to tell you exactly.
Contractors who pressure you into signing quickly or who ask for a large cash deposit before any work starts should be treated with caution. It is reasonable to pay a stage payment when materials are ordered for large jobs, but the terms should be agreed in writing before you commit.
When you have two or three quotes in front of you, the most important thing is to check whether they are specifying the same work. A quote for a 1.2mm EPDM membrane on 100mm insulation board is not the same as a quote for a 1.5mm membrane on 150mm board. The price difference is real, but so is the difference in what you get.
Ask each contractor to confirm in writing what membrane system, gauge or thickness, and insulation specification they are pricing. Once you can compare like for like, the choice becomes much clearer. Typical commercial flat roof replacement costs in the UK run from around £70 to £150 per square metre, depending on system specification and the complexity of the roof. That range reflects genuine differences in what is being installed, not just contractor margin.
Not every commercial roofing problem requires a full replacement. Isolated lap failures on a metal roof, localised membrane splits on a flat roof, or blocked and overflowing outlets can often be addressed with targeted repair work. The question of whether to repair or replace is covered in more detail on our Brandon page, but in brief: if a roof has reached the end of its serviceable life and is failing in multiple places, repeated repairs become more expensive and more disruptive than a planned replacement.
A proper condition survey - physically inspecting the surface, the drainage, the upstands, and any accessible substrate areas - is the only reliable way to make that call. Do not rely on a drive-past or a report based on photographs alone.
Commercial gutters carry significant volumes of water. Undersized, poorly pitched, or poorly maintained guttering is a common cause of water ingress into walls and foundations. When a roof is re-covered, it is worth reviewing the gutter capacity and fall at the same time. We install and replace commercial rainwater systems, fascias, and soffits alongside roofing projects or as standalone work.
