What's involved

Commercial Roofing in your area

Commercial roofing covers a wide range of building types — warehouses, offices, retail units, schools, farm buildings, and light industrial premises. What these buildings share is that a failing roof can shut down operations, damage stock, and expose owners to liability if water ingress is left unaddressed. We work across Thetford and the surrounding Norfolk area on new-build commercial projects and maintenance contracts alike.

The work we carry out most often on commercial roofs includes felt and GRP flat roof replacement on single-storey extensions and outbuildings, single-ply membrane installation on larger flat roofs, box profile and standing seam metal roofing on agricultural and industrial units, and the repair or replacement of roof lights and guttering on commercial premises. We work from detailed drawings where available, or survey and specify the job ourselves for straightforward repairs and replacements.

Commercial roofing requires proper access equipment, health and safety planning, and the right insurance. We use scaffolding or MEWP (mobile elevated work platforms) depending on access requirements, and we produce method statements and risk assessments for any project where the building is occupied during the works. This protects both your business and our team.

Before we start, we agree a programme of works with you so you know exactly when each phase will happen and how access to the building will be managed. Most commercial flat roof replacements on units up to 500 square metres take three to five working days. We carry £5 million public liability insurance and offer a minimum ten-year guarantee on all new roofing systems.

Commercial flat roof replacement in Thetford typically costs between £70 and £120 per square metre for a single-ply membrane system, depending on insulation specification and existing roof condition.

Questions

What people ask first.

Most new roofs on a three-bedroom semi-detached house in Thetford cost between £5,500 and £9,000 using concrete interlocking tiles. Natural slate or clay tiles will push the price toward £10,000–£12,000 or more depending on roof area and complexity. We provide a written, itemised quote after a free survey so you know exactly what you're paying for.
If your roof has isolated slipped or cracked tiles, a repair is usually sufficient. However, if you're seeing widespread tile failure, daylight through the roof space, or your felt underlay is brittle and crumbling, a full replacement will be more cost-effective. We'll give you an honest assessment during a free survey — we won't recommend a replacement if repairs will genuinely solve the problem.
Most straightforward repairs — replacing a few broken slates, re-bedding a loose ridge tile, or resealing a small flashing — cost between £150 and £400 in Thetford. More involved repairs such as renewing a full run of ridge tiles or replacing a section of lead valley can reach £500–£800. We always provide a fixed quote before starting work, so there are no unexpected charges.
Flat roof replacement in Thetford typically costs between £70 and £120 per square metre, fully installed. A standard garage roof of around 20 square metres would therefore cost roughly £1,400 to £2,400. GRP and EPDM systems sit toward the top of that range, while a torch-on felt system is generally at the lower end. We provide a fixed, itemised quote after surveying the existing roof.
For a standard three-bedroom semi-detached house in Thetford, fascia, soffit, and guttering replacement typically costs between £800 and £1,800. The price depends on the total run of roofline, whether any rafter feet need repair, and how many downpipes are involved. We provide a fixed written quote after a free site survey so you know exactly what you're paying before work begins.
Common signs include damp patches on ceilings near a chimney breast or roof window, visible cracks or gaps in the lead itself, or lead that has pulled away from the brickwork. Sometimes the lead looks intact but the mortar chase holding it has eroded — water then tracks behind it invisibly. If you're seeing any internal damp near a roof junction, it's worth having the flashings inspected before the damage spreads to the roof timbers.
Repointing is sufficient when the brickwork itself is sound but the mortar joints between courses have eroded. A rebuild is needed when the bricks are cracked, spalling, or have moved structurally — for example, if the stack is visibly leaning or sections of brickwork have loosened. We inspect from scaffold level to give you an honest assessment rather than guessing from ground level.
In most cases, removing a chimney stack from a standard domestic property falls under permitted development and does not require planning permission. However, if your home is a listed building or sits within a conservation area — which applies to parts of Thetford town centre — you will need to seek consent before any work begins. We can advise you on this during our free survey and recommend you check with Breckland Council if there is any doubt.
