What's involved

Commercial Roofing in North Walsham

Commercial roofing covers a wide range of building types — retail units, warehouses, office blocks, farm buildings, schools, and industrial sheds. The roofing systems used on these buildings differ significantly from domestic properties, and getting the specification wrong can lead to premature failure, voided warranties, or water ingress that disrupts your operations. We work with building owners, facilities managers, and landlords across North Walsham and the wider North Norfolk area.

The work we carry out includes flat roof installation and replacement using GRP, EPDM rubber, and single-ply membranes; pitched roof re-covering in fibre cement, profiled steel, or natural slate; box gutter relining; lead work on parapet walls; and emergency repairs following storm damage. We also carry out condition surveys and produce written reports, which are useful for commercial property transactions or insurance purposes.

Commercial roofs are typically larger and more complex than domestic ones, with multiple penetrations for plant, skylights, extraction units, and guttering systems. Each of these is a potential leak point if not properly detailed. A poorly specified flat roof membrane, for example, can fail within five years, whereas a correctly installed EPDM system should last 25 years or more with minimal maintenance.

We start with a thorough inspection of the existing roof structure and covering. You receive a clear written quote broken down by material and labour. We can work around your business hours where required — early starts and weekend working are options we discuss at the quoting stage. We are fully insured for commercial works, including public liability, and all installations come with a written guarantee.

Commercial flat roof replacement in North Walsham and North Norfolk typically costs between £70 and £120 per square metre for a single-ply or EPDM system, installed.

Questions

What people ask first.

For a standard semi-detached or detached house in North Walsham, a new roof typically costs between £5,500 and £12,000. The price depends on the size of the roof, the pitch, the materials chosen, and whether any structural timbers need replacing. We provide a full written, itemised quote after a free survey so there are no surprises.
If more than 25–30% of tiles or slates are damaged, if the felt underlay has broken down and water is getting into the roof space, or if you've had repeated leaks in different areas, replacement is usually more cost-effective than ongoing repairs. We offer a free roof survey and will give you an honest assessment — we won't recommend a replacement if repairs are the right answer.
Minor repairs such as replacing a few slipped or broken tiles typically cost between £150 and £350 in North Walsham. More involved jobs like re-bedding ridge tiles along a full ridge, or replacing lead flashings around a chimney, usually range from £400 to £900. We always provide a written quote before starting so you know exactly what you'll pay.
Flat roof installation in North Walsham typically costs between £70 and £120 per square metre, depending on the system and the condition of the existing deck. A standard single-car garage roof of around 15 square metres would usually cost between £1,100 and £1,800 fully installed. We survey the existing structure before providing a written quote, so there are no surprises if the deck needs replacing.
For a typical three-bedroom semi-detached in North Walsham, replacing fascias, soffits, and guttering in uPVC usually costs between £900 and £1,800. The price depends on the size of the property, the number of downpipes, and whether any rafter feet need treating or replacing. We provide a fixed written quote before any work begins.
Replacing the lead flashing on a standard single chimney stack in North Walsham — including step flashings, cover flashings, and a back gutter — typically costs between £250 and £550. Larger or more complex stacks with multiple sides or decorative brickwork will sit toward the higher end. We quote on site after inspecting the stack so there are no surprises.
A chimney rebuild from the lead flashing level on a typical two-storey house in North Walsham costs between £1,200 and £2,500. The price depends on the height of the stack, how many flues it contains, and how much brickwork needs replacing. We provide a detailed written quote after inspecting the stack from scaffold or, where access allows, with binoculars from the ground first.
Taking down a chimney stack and making good the roof on a typical North Walsham property costs between £1,000 and £2,000. The price varies depending on the height of the stack, the number of flues, and the size of the roof area that needs tiling or slating back in. We include scaffold erection and full debris removal in all our quotes.
