Commercial Roofing Services Near Lakenheath

Brandon Roofers covers commercial properties in and around Lakenheath. We work on all types of commercial buildings: industrial units, retail and trade premises, warehouses, storage buildings, and offices. Whether the job is a straightforward repair, a full roof replacement, or a new flat roof covering on an extension or outbuilding, the work needs suitable access equipment and experience to be done safely and properly.

On this page, we focus on something that commercial property owners and managers often find difficult: choosing the right roofing material for the job. There is a real range of options, each with honest advantages and drawbacks. Making the right choice at the start saves money over the life of the roof.

The Main Commercial Flat Roofing Systems Available

Commercial flat roofs in the UK are covered by one of a small number of systems. The choice between them depends on the size and shape of the roof, the deck type, the number of penetrations and upstands, the budget, and how long you need the roof to perform before the next significant spend.

Torch-On Felt (Built-Up Felt Systems)

Torch-on felt, also called modified bitumen or SBS felt, is applied in layers using a gas torch to bond each layer to the one below. A standard commercial specification uses two or three layers, with a mineral-faced cap sheet on top. It is one of the most widely used commercial roofing materials in the UK.

Honest pros:

• Relatively straightforward to install on most commercial decks.
• Repairs and patches are easy to carry out using the same material.
• Good adhesion to a variety of substrates including concrete, timber, and metal decking.
• A correctly installed system typically performs for 15-20 years before replacement is needed.
• Material and labour costs are generally lower than single-ply for small to medium areas.

Honest cons:

• Fire risk during installation: torch-on felt requires a hot works permit on many commercial sites, and surrounding structure must be protected.
• Less tolerant of movement than single-ply membranes. On steel-framed buildings with significant thermal movement, lap seams and upstand details need careful attention.
• Heavier than single-ply, which matters on older decks with limited imposed load capacity.
• Surface degrades over time if not maintained: splitting, blistering, and lap failure become more likely in the last few years of the system's life.

Cold-Applied Liquid Coatings

Liquid-applied systems are polymer-modified coatings that are painted or rolled onto the roof surface and cure to form a seamless waterproof layer. They are particularly useful for roofs with complex shapes, large numbers of penetrations, or existing coverings that cannot practically be stripped.

Honest pros:

• No open flame during application, which removes the hot works risk entirely.
• Genuinely seamless across the surface: there are no laps to fail, which is an advantage on roofs with many penetrations and upstands.
• Can be applied over existing felt in some circumstances, avoiding strip-out costs.
• Good UV resistance in modern formulations.

Honest cons:

• Quality of application is critical. Thin or uneven coating, particularly around upstands and penetrations, leads to early failure. The final thickness needs to be checked during installation.
• Not suitable for roofs with structural defects, soft decking, or standing water problems. The liquid simply covers problems rather than resolving them.
• Some formulations require dry conditions and minimum temperatures during application, which can restrict the working window on exposed sites.
• A full replacement of a failed liquid coating is more complicated than removing a felt system.

EPDM Rubber Membrane

EPDM (ethylene propylene diene monomer) is a synthetic rubber membrane supplied in large sheets, which are bonded to the deck using adhesive. It is extremely flexible and well suited to roofs that experience thermal movement.

Honest pros:

• Highly flexible and tolerant of movement: it does not crack under thermal stress in the way that aged felt does.
• Lightweight compared to built-up felt, which is a practical advantage on older structures.
• No open flame: cold adhesive bonding removes hot works risk.
• EPDM membranes are known to perform for 30 years and beyond when correctly installed and detailed, making them a strong choice where longevity is the priority.
• A smooth surface that does not encourage moss growth in the way that mineral-faced felt can.

Honest cons:

• Material and installation costs are generally higher than torch-on felt for equivalent areas.
• Detailing at penetrations and upstands requires a different set of skills and specific EPDM flashing products. Poorly detailed junctions are the most common failure point.
• Repairs require compatible EPDM tape or patch material: standard bitumen products will not bond reliably to rubber membrane.
• Large-sheet installation requires care to avoid trapped air bubbles during bonding, particularly on warm days when the adhesive tacks quickly.

Single-Ply Thermoplastic Membranes (TPO and PVC)

Single-ply thermoplastic membranes, most commonly TPO or PVC, are widely used on large commercial and industrial roofs. They are installed as a single layer, either mechanically fixed, fully adhered, or ballasted, and seams are welded together using hot air equipment.

Honest pros:

• Hot-air welded seams are extremely strong and reliable when done correctly, eliminating the lap failure that is common with aged felt.
• Light weight: single-ply adds minimal load to the structure.
• Fast to install on large, open roof areas, which can reduce labour costs on big commercial projects.
• Good root resistance if the building is in an area where vegetation growth is a concern.
• Available in a range of colours, including white and light grey, which can reduce solar heat gain through the roof deck in summer.

Honest cons:

• Hot-air welding equipment requires operator skill. Poorly welded seams are a common failure point and can be difficult to detect visually until a leak occurs.
• PVC membranes can be susceptible to degradation if they come into contact with certain bitumen products or plasticisers, which is relevant on re-roofing projects where existing felt is not fully stripped.
• Mechanically fixed systems require the fixings to be appropriate for the deck type: incorrect fixing specification can lead to pull-out failure under wind uplift.
• Higher initial cost than torch-on felt, though the longer expected service life often justifies this over a 20-30 year horizon.

How to Choose Between Systems

For most commercial property owners in Lakenheath and the surrounding area, the decision comes down to three questions: How long do you need the roof to last? What is the deck condition? What is your budget for the initial installation versus ongoing maintenance?

Torch-on felt is a sound choice for a straightforward commercial re-roof where budget is a constraint and the deck is in good condition. EPDM suits buildings where movement is a factor and long service life is the priority. Single-ply works well on large, open industrial or warehouse roofs where the welded seam system genuinely earns its installation cost. Liquid coatings are most useful on complex shapes or as a bridge solution where a full replacement is not immediately viable.

A good roofer will inspect the deck, measure the falls, look at the drainage arrangement, and consider the type of building before recommending a specific system. Be sceptical of any contractor who recommends the same product for every job without surveying the roof first.

Insulation: Do Not Overlook It

Commercial flat roof replacement is one of the few opportunities to upgrade insulation in a building without major disruption. Warm-roof construction, where rigid insulation sits above the waterproof membrane (or between the membrane and the deck on an inverted system), significantly improves thermal performance and reduces the risk of condensation within the roof build-up.

Minimum insulation values for commercial roofs are set by Part L of the Building Regulations. A full replacement carried out without upgrading the insulation to current standards may not comply, so it is worth confirming the specification before work begins. PIR board is the most common rigid insulation used in commercial flat roofing; phenolic boards offer slightly better performance per millimetre where headroom is limited.

Typical Costs for Commercial Roofing in the UK

Commercial flat roof replacement typically costs between £50 and £120 per square metre in the current UK market, depending on the system, the condition of the existing deck, access requirements, and whether the existing covering needs to be stripped. Torch-on felt installations on straightforward decks tend to sit toward the lower end of that range. EPDM and single-ply systems with upgraded insulation tend to sit higher. These are indicative figures only; a proper survey is essential before any quotation can be meaningful.

Repairs are costed separately and depend entirely on the nature and extent of the failure. A localised repair to a failed upstand or a patch over a blister is a very different scope to widespread crack repair across an ageing felt surface.
