Metal roofing is used by industrial building owners more than other materials. Most commonly this is in the form of corrugated metal roof sheets. The reason for the popularity of metal roofing sheets compared to other roofing materials is due to the many benefits they provide.
Metal roof sheets are extremely durable which means the industrial roof waterproofing is long lasting and excellent value for money. Also metal roofing sheets are energy efficient, environmentally friendly and lightweight. These benefits combined with excellent fire resistance make metal roof sheets stand out compared to other roof materials (1). And make it perfect for protecting buildings with high value contents. It is also an easy system to maintain if problems do occur over time.
However, to get the most of a metal roofing system pro-active maintenance is strongly advised. As mentioned before a huge plus point for metal industrial roofing systems is they are easily refurbished with a liquid coating. This does not just mean repairs to the roofing system, it includes improving the roofs aesthetics. Old poorly maintained roofs do not look good for visiting clients. Maintenance with liquid coatings can be offered in a range of colours to make the roofing attractive, modern, and classy. Additionally, you increase the value of your property by installing it. Most property owners consider this process as an investment.
Such a service can be carried out efficiently without impacting the operations of the building below. The best way to do this is normally with a PU liquid coating. This is applied to the corrugated roof sheets. Once applied this coating is able to repair, rejuvenate and maximise the lifespan of the roof. It gives the corrugated sheets protection for up to 25 years. In many cases this significantly extends the service life of the metal roof. This liquid coating can be applied to both industrial roofing and cladding.
Currently we are able to supply and install a coating on an industrial metal roof for between £35 per SQM and £45 per SQM. The main variable in this is the size of the roof. This pricing carries an insurance backed warranty as we are an approved roofing company of the liquid waterproofing manufacturers. This means:
• Full liquid waterproofing without the need for replacement.
• Fast and efficient installation.
• Application by certified practitioners using specialist approved coatings.
• Can be colour matched to complement your branding.
Most leaks on metal roofs are caused by failing roof screws. The way in which screws are used in a metal roof system is to fix the roofing sheets. The screws compress a rubber washer at the screw head’s base. Overtime these screws will come loose leaving the opportunity for water ingress. It is money well spent to invest in regular roof surveys to identify such problems early. This is a practice which can significantly extend the roofs lifespan. Without carrying out regular surveys and maintenance work an exposed metal fastener roof can last as little as 10 years.
Between the age of 10 and 15 years such as system is going to require a re-screw. As these roofs age the best solution to ensure longevity is to apply a roof coating. The application of a roof coating can add many years on to the lifespan of a metal roof, which will really maximise the return on the initial cost to install the system. The way in which a roof coating is applied is by using butyl tape to secure all the joints and seams on the roofing sheets. All screws, nails and fasters are covered with butyl caps. Then the liquid coating is applied to the steel cladding. This process will rejuvenate the roof in terms of its waterproofing ability and aesthetics.
The types of roof sheets which are used in metal roofing are normally a form of corrugated metal roof sheets. These are normally galvanised steel roofing sheets which are then coated with a PVC plastisol coating for colour (2). There are also zinc, copper, lead and aluminium systems (these are more frequently seen on residential properties as an alternative to traditional roofing tiles). Additionally, some older metal systems use corrugated roof sheets made from iron. However, galvanised steel roof sheets are by far the most common and cost effective metal roofing material.
Metal roof cladding can last up to 40 years. Metal roofing offers the best longevity for commercial buildings of any industrial roof cladding system. The key point to ensuring your industrial roof cladding can last for this length of time is to look after it. This means regular surveys and getting the required maintenance work carried out when necessary. Examples include; if corrosion is noticed on the metal surface cut edge corrosion treatment should be applied. Or if the PVC plastisol wears out a specialist roof coating should be applied. Another problem is loose screws which need to be re-fixed to prevent issues such as leaking. If regular surveys and maintenance is adhered to, metal roofing sheets should have a long life span which exceeds the guarantee given.
