Bury St Edmunds Roofers provides commercial roofing in Lakenheath, covering flat roof systems, single-ply membranes, built-up felt and profiled metal roofing for local businesses and premises.
When a commercial roof fails, the cost is rarely just the roofing work. Damage to stock, interrupted trading, temporary coverings and emergency call-outs all add up. Getting the right system installed from the start - or choosing the right repair approach when something goes wrong - saves money over the life of the building.
We carry out commercial roofing across the Lakenheath area and the wider Suffolk region from our base in Bury St Edmunds. The work covers flat roof replacements, single-ply membrane installations, built-up felt systems, profiled metal roofing, and maintenance and repair across all of those systems. Below, we go through the main material options honestly, including their strengths and the situations where they are not the best fit.
Choosing the right flat roof system is the most important decision a building owner or facilities manager will make. There is no single "best" system. Each one suits different budgets, building uses and roof sizes.
Built-up roofing uses multiple layers of bitumen felt, bonded together and finished with a mineral surface or solar-reflective coating. It has been used on commercial buildings for decades and is well understood by roofers and building surveyors alike.
Honest pros: Lower upfront material cost than membrane systems. Suitable for large, simple roof areas. Repairs are straightforward and most roofers can carry them out. The system is robust under foot traffic during maintenance visits.
Honest cons: A standard three-layer felt system typically lasts 15-20 years before full replacement becomes necessary. Seams and laps are potential weak points if not properly torched and pressed. It performs less well than modern membranes on roofs with complex details, penetrations or heavy plant.
Typical installed cost for a commercial built-up felt roof in Suffolk currently ranges from around £40 to £65 per square metre, depending on the number of layers specified and the complexity of the roof.
Single-ply systems use a single layer of synthetic membrane - usually EPDM rubber, TPO or PVC - mechanically fixed, adhered or ballasted to the roof deck. They have become the dominant commercial flat roof system over the past 15 years.
Honest pros: EPDM in particular has a strong long-term track record, with manufacturer material lifespans cited at 30-50 years when correctly installed. Single-ply systems handle movement in the building structure well, which matters on larger spans. Seams are heat-welded (TPO/PVC) or bonded with tape (EPDM), reducing lap failures when done properly. Lighter than built-up systems, which is relevant on older roof decks with load limits.
Honest cons: Higher upfront cost than felt - expect £60 to £100 per square metre installed for a single-ply commercial system. Not every roofer works with every membrane type, so check that the contractor has genuine experience with the specific product. EPDM is black and absorbs heat, which can increase cooling loads on buildings that require climate control. TPO and PVC are available in lighter colours if that matters.
For a 200 square metre flat roof, the difference between felt and single-ply in material and labour cost could be £4,000 to £7,000. On a building that will be owned or occupied for 20 or more years, the longer service life of a single-ply system often makes it the lower-cost option over time.
Profiled steel or aluminium sheeting is the standard choice for industrial buildings - warehouses, agricultural units, storage facilities and large retail sheds. It can also be used for extensions or canopies on smaller commercial premises.
Honest pros: Extremely durable. Steel roofing with a factory-applied polyester or plastisol coating typically carries a manufacturer's finish life of 25-40 years, though the coating will need inspection and maintenance. Very fast to install on large spans, reducing site time and disruption. Insulated composite panels (built with insulation bonded between inner and outer metal faces) achieve high thermal values in a single installation visit.
Honest cons: Metal roofing is not suitable for retrofit over existing felt or membrane without structural assessment, as it adds load and requires a compatible substructure. It is noisy in heavy rain unless the building is insulated to a good standard. Penetrations, rooflights and guttering all need careful detailing - this is where most metal roof failures begin. Repairs to damaged sheets are more involved than patching felt.
Profiled metal roofing typically costs £50 to £90 per square metre for standard single-skin sheeting. Insulated composite panel systems run higher, from around £80 to £130 per square metre, but they remove the need for a separate insulation installation.
Not every problem on a commercial roof requires a full replacement. Localised failures around flashings, upstands, outlets and penetrations account for a large proportion of commercial roof leaks. A proper inspection - up on the roof, not just a visual from ground level - will identify whether the issue is isolated or a sign of wider membrane or felt degradation.
Common problems on older commercial roofs include:
Repair costs vary widely depending on what the investigation finds, but a flashing replacement or outlet repair on a small commercial roof typically runs from £300 to £800. A like-for-like patch repair on felt or EPDM is usually in the £200 to £600 range for a localised area.
Some commercial premises in Lakenheath and the surrounding area carry a pitched roof - offices in converted houses, smaller retail units, or buildings with a tiled or slated section alongside a flat extension. We cover pitched roofing work on commercial buildings as well as domestic properties, including re-roofing, tile and slate replacement, ridge and hip work, and lead valleys.
Commercial guttering and fascia work is often overlooked until it causes a problem. Failing guttering on a warehouse or office block allows water to saturate the wall below and track into the building fabric. We carry out commercial guttering replacements in cast iron, aluminium and UPVC, as well as soffit and fascia cladding where the existing timber has deteriorated.
Commercial roofing work needs to fit around the building's operation. Before any job starts, it is worth discussing how the site will be managed during the work - access arrangements, protection of goods or equipment below, and a realistic programme. Profiled metal and single-ply systems can often be installed over an existing roof (subject to a load and condition assessment), which removes the disruption of stripping a building while it is still occupied.
Whether you are getting quotes for a full roof replacement or a repair, there are a few things worth confirming with any contractor:
Getting clear answers to those questions before work starts avoids most of the disputes that arise on commercial roofing projects.
