A failing commercial roof does not wait for a convenient moment. Whether you run a retail unit, a workshop, a storage facility, or a farm building, the roof is working every hour of every day. When something goes wrong, the decisions you make in the first few hours matter as much as the repair itself.
We cover the full range of commercial roofing work across Stalham and nearby towns and villages in North Norfolk. That includes flat roof repairs and replacements, pitched roof work on agricultural and industrial buildings, leadwork, guttering, upstands, flashings, and new roof installations on commercial premises of all sizes.
Commercial roofing is not the same as domestic work, even when the materials overlap. The scale is larger, the access requirements are different, and the consequences of a failure are higher. A leaking roof on a workshop can halt production; on a cold-storage unit it can mean a lost stock consignment; on a retail space it can mean closing the doors.
Flat roofs are among the most common commercial roofing systems and also the most frequently misunderstood. A well-installed flat roof is not actually flat - it has a slight fall built in to drain water towards outlets. When that fall is lost, or when outlets block, water pools and the membrane deteriorates faster. Felt systems typically last 10 to 20 years depending on specification and maintenance. EPDM rubber membranes generally last longer - manufacturers rate many at 25 years or more - but installation quality makes a significant difference to how long either system performs in practice.
Pitched roofs on commercial and agricultural buildings bring their own challenges. Large spans, heavy loads, and the use of profiled steel sheeting or fibre cement sheets mean that fixings, laps, and ridges all need careful attention. Corrosion at fixings and lap joints is a common source of leaks on older agricultural buildings. Replacing like-for-like is usually straightforward; upgrading to a better specification takes more planning but often pays for itself in reduced maintenance.
Pricing varies significantly depending on roof size, access, materials, and the extent of any structural work underneath. As a general guide for the North Norfolk area:
These are indicative ranges only. Any responsible contractor will assess the roof before giving a price. Be cautious of any quote given without a proper inspection.
This is the section most commercial customers wish they had read before something went wrong. When a roof fails during business hours - or overnight before you discover it on a Monday morning - there are practical steps you can take that will limit damage, protect your property, and make the roofer's job easier. There are also things that look sensible but can make the situation worse.
Your first job is to protect what is inside the building, not to fix the roof itself. Move stock, equipment, and anything vulnerable away from the area directly below the leak. Put buckets or bins under active drips, and lay absorbent matting or old towels around them to stop water spreading across the floor. A wet floor in a commercial premises is a slip hazard, and a liability issue, so deal with it quickly.
If water is entering through a ceiling void and the ceiling starts to bulge, keep everyone out of the area below and do not poke, prod or pierce it - a waterlogged ceiling can come down without warning.
Take photographs and video of the leak point, the water damage, and anything affected. Do this before you move stock or attempt any temporary measures. If you need to make an insurance claim, or if there is any question later about the cause or extent of the damage, that evidence is invaluable. Date-stamped photos on a phone are perfectly adequate.
Note the time you first noticed the problem and any relevant weather conditions - heavy rain, strong wind, an overnight frost followed by a thaw. A roofer arriving to assess the damage will find this information useful in diagnosing the cause, especially on flat roofs where the entry point and the visible damage are often some distance apart.
If water is tracking near lighting, sockets, distribution boards, or any electrical equipment, isolate that circuit at the consumer unit or isolator switch immediately. Do not wait to see whether the water reaches the fitting. Water and live electrics together can cause a fire or an electrocution risk, and the damage to electrical systems is expensive to repair. If you are unsure which circuit to isolate, turn off the main isolator and call an electrician as well as a roofer.
When you call a roofing contractor, the more accurate your description, the better they can prepare. Tell them the type of building, the approximate roof area, whether it is flat or pitched, what the roof covering is if you know, where on the roof the problem appears to be, and how long the leak has been active. This helps the roofer bring the right materials and equipment to make a temporary repair if a permanent fix cannot be completed on the same visit.
Ask the contractor whether a temporary repair is possible on the first visit, or whether a full survey will be needed first. On a complex commercial roof, a proper survey often takes priority over rushing in with a repair that may not address the underlying cause.
The temptation to get on the roof yourself and see what is happening is understandable. In most cases, it is a bad idea, and in some cases it can make a difficult repair much more expensive.
Flat commercial roofs often have fragile or rotten decking beneath the membrane. From the surface, there is no way to tell where the deck is sound and where it has deteriorated. A person walking on a weak section can punch through, causing a serious fall or a significantly larger hole in the roof than the one you started with. Roofers use access equipment and crawl boards to spread their weight precisely because of this risk.
Even on a structurally sound deck, walking on a felt or EPDM membrane without protective boards can crack aged material, split laps, or displace ballast on a ballasted system. You can cause a new leak while investigating an existing one.
Roofing sealants, mastic, and bitumen-based products are sold as emergency fixes, and there are situations where they do provide a short-term solution. The problem is that some of these products - particularly silicone-based ones - contaminate the surface they are applied to. Silicone prevents new roofing adhesives and primers from bonding, meaning that when a roofer arrives to carry out a proper repair, they have to spend additional time and money removing the contaminated area before they can start the actual work. In some cases the contamination is extensive enough to require a larger area of membrane replacement than the original fault would have needed.
If you are going to use a temporary product, use a butyl tape or a bitumen-compatible patch product, and tell the roofer exactly what you have applied before they start work. Silicone - even clear silicone - should not go on a roofing membrane.
A tarpaulin weighted down or tied off can provide short-term weather protection on a pitched roof, but it needs regular checking. Tarpaulins can move in wind, especially on an exposed site, and a tarpaulin that shifts and funnels water into a gap can cause more water ingress than the original hole. On a flat roof, a tarpaulin rarely works well at all - it can trap water rather than shedding it.
If a temporary cover is in place, inspect it after every period of wind or rain and tell your roofing contractor it is there. Do not let a temporary measure become a long-term one. The longer a damaged roof is left, the more likely water is to reach the structural elements beneath, and structural repairs are significantly more expensive than roofing repairs.
A drip that appears during heavy rain and then stops is easy to file away as something to deal with later. On a commercial flat roof, a small active leak almost always indicates a larger area of deteriorated or delaminated membrane nearby. Water travels along the path of least resistance and can enter at one point and appear inside the building at a completely different location. A small leak dealt with promptly is a simple repair. The same leak left for six months can mean a full section of roof replacement.
Whether you are dealing with an emergency or planning a scheduled replacement, the questions you ask before appointing a contractor will save you problems later.
The most cost-effective approach to any commercial roof is a programme of regular inspection and planned maintenance rather than waiting for problems to appear. An annual inspection of a flat roof - checking outlets, upstands, flashings, and the condition of the membrane surface - typically costs very little relative to the cost of an emergency call-out and repair. Many leaks found at inspection are simple to address: a blocked outlet, a lifted flashing, a small split at a lap joint.
For businesses in Stalham and across North Norfolk, getting a roofer to carry out a condition report before winter is sensible. Wind and frost are common causes of roof failure, and a roof in borderline condition going into the colder months is a roof likely to fail at the worst possible time.
Many existing commercial flat roofs were built with felt systems. These are proven materials when correctly installed and regularly maintained. Problems arise when laps are not adequately bonded, when the decking below is not properly prepared, or when the falls are insufficient.
EPDM rubber membrane has become increasingly common on commercial roofs over the past decade. It is installed cold - no open flame - and a correctly installed system is highly resistant to ponding water, UV degradation, and thermal movement. The material itself has a long track record in commercial applications. The key factor in any membrane's lifespan is the quality of the installation, particularly at details: upstands, penetrations, internal and external corners, and outlet connections.
When replacing a flat roof, the choice of system should be driven by the specific roof - its falls, its decking condition, the number of penetrations, and how it is used - not simply by cost or habit.
If you have a commercial roof that is leaking, showing signs of wear, or due for replacement, call us to arrange a roof survey. We will assess the condition of the covering, the decking, the falls, the outlets, and the flashings, and give you a clear picture of what is needed and why. We cover Stalham and the wider North Norfolk area from our base in North Walsham.
