If you’re about to construct a new building, or replace the roof of an existing one, make sure you plan the whole process with precision from start to finish to ensure optimum success.

Do you need planning permission?

Under legislation introduced in April 2010 relating to warehouses and industrial buildings, the erection, alteration or extension of an industrial building does not require an application for planning permission. The only exception is if your property is a listed building. Planning permission will still be required in these circumstances.

How much weight will the roof be holding?

The strength of the roof depends on whether it has a structural cement deck, or whether it's a wood or sheet metal roof. Consider whether you'll need it to support an air-conditioning unit, or any other equipment used by your business. Will any employees need to go on the roof periodically to service equipment?

Will the roof boost your business's energy-saving efficiency?

Are you planning to coat your roof with reflective material, which maintains a lower temperature, reducing the need for air conditioning in the summer? Will it be insulated to reduce your heating bills in colder weather? The type of materials and insulation can affect your future energy bills.

How long are you anticipating occupying the building?

If your company's ownership, or leasing, of the building is expected to be only short-term, your requirements for the roof might be different from your needs, should you envisage long-term occupancy of the premises. If you are in for the long haul, remember this will mean years of battling all kinds of weather.

Different types of roofing

Take into account the variety of roofing that's available and choose the one that's most suited to your company's needs:

Thermoplastic (TPO) roofing is a popular, commercial roofing system. It's made of durable material which has high-temperature tolerance and low-temperature flexibility. TPO roofs are resistant to ozone, ultraviolet and chemical exposure and normally have a lifespan of more than 20 years. They're also highly-resistant to fire, high winds and punctures.

Ethylene propylene diene terpolymer (EPDM) roofing offers excellent durability and versatility. It's known to be one of the longest-lasting kinds of commercial roof available and it's easier to install, repair and maintain than many other types of roof. It comprises a roofing membrane made of synthetic rubber (EPDM) which is often used for low-slope buildings. It has two main ingredients, propylene and ethylene.

In an effort to save money on energy costs and utilise sustainable energy, some businesses are turning to photovoltaic solar panels in their roof. Solar roofing systems involve having PV solar panels installed over the rooftop. They can also be constructed using glass, membrane and roof-mounted tiles. Solar panels convert sunlight to energy, which can be used to power the building. Solar roofs are not widely used, but have the potential to save a lot of money on energy costs. Until 2012, commercial and agricultural properties needed planning permission to have solar panels fitted, but this is no longer the case.
