FAQs

Am I liable for a leaking roof in a commercial property?

Whether you’re liable for a leaking roof in a commercial property will depend on your ownership status and any contracts. Of course, if you own a standalone commercial property, it would make it your responsibility to repair to leaking roof. But if you own an office within a building, you should check your paperwork to see whether you are responsible for some or all of a leaking roof.

If you’re a tenant in a commercial property, things get a bit more complicated. Lots of commercial leases are FRI, or Full Repairing and Insuring leases, which means that the tenant is responsible for all external and internal maintenance and insuring the building. It means that it’s vital that you read through your tenancy agreement in full before signing it and seek legal advice if you think you need it. If your lease is an FRI lease, you are liable for a leaking roof in your commercial property.

It’s important to ensure that you have a schedule of condition for the property, which will mean that you only have to restore the commercial property back to the condition that it was in when you took over. It’s also worth getting the roof inspected before you sign the lease, as if there is any damage before you sign the landlord may be responsible.

The best way to avoid having to pay for a leaking roof in a commercial property is prevention. If you are liable for repairs and maintenance, make sure you have the roof inspected regularly by a reputable company to avoid having to pay for costly repairs when disaster strikes.

How much does it cost to replace a commercial flat roof?
If your commercial flat roof needs replacing, how much it costs will depend on how big the roof is and what you want it to be made from. Lots of commercial flat roofs are made from felt or asphalt, but people are also beginning to turn to materials like EDPM rubber and fibreglass. Flat roofs can last a long time, but if it’s been 20 years or more since you had it replaced or inspected, it might be time for a new one. If a roofer inspects it and finds lifting, flashing problems, sagging or lots of blisters, it’s probably time to replace your flat commercial roof. So how much does it cost to replace your commercial flat roof? The average cost is around £4,500, but it could be much less or much more. It depends on how big your roof is and what material you choose. Felt is the cheapest material you can use for your commercial flat roof, at around £40-70 per metre squared, while a lead bay roof will cost the most at £90-110 per square metre. EDPM rubber and fibreglass roofs are being used more and more because they’re so durable, and they will cost between £80 and £110 per square metre. It might be worth spending a little more upfront to get a stronger and longer-lasting commercial flat roof.

What is commercial roofing?

Commercial roofing simply refers to any roofing work, including installation and repair, that is done to commercial buildings. This might include office roofs, shop roofs or commercial unit roofs. Every building needs a roof to keep out the rain!

Since looks aren’t usually the first priority with commercial buildings, lots of commercial properties have flat roofs. These are often made from felt, EDPM rubber or fibreglass. Felt is the cheapest commercial roofing material, while fibreglass tends to be the most expensive. In felt roofs, roofers use an adhesive to stick roofing felt onto a frame. EDPM rubber roofs have a rubber membrane that is laid down and glued onto the roof and coated with a contact adhesive, while fibreglass uses a cut glass fibre mat that is pressed on before a resin and topcoat are applied.

Not all roofing companies will offer commercial roofing services, because generally the buildings tend to be bigger. Small companies won’t have enough tradespeople to work on a roof without making it very expensive for you. Commercial buildings also tend to need more scaffolding to make it safe for the professionals to work, so some smaller roofing companies won’t offer commercial services. Make sure you check a company’s website or social media if you’re looking for commercial roofing – on the Quotatis Directory, our roofers will show whether they do commercial roofing to make your search easier.

What is the best commercial roofing material?
The best commercial roofing material for your building will depend on the size and type of roof you have as well as your budget. A lot of commercial buildings have flat roofs, but some have pitched roofs. These days, flat roofs are almost flat, but are usually built on a small slope so water can drain effectively. Pitched roofs are much steeper and are made using tiles or shingle. Our top choices for commercial flat roofs would be fibreglass or EDPM rubber. Both of these materials will set you back around £80-110 per square metre, making them some of the most expensive flat roof materials, but they’re strong and durable. A fibreglass roof consists of a cut glass fibre mat that is pressed on the roofing frame, then resin is poured and rolled over the roof before a topcoat is applied. An EDPM roof involves laying an EDPM rubber membrane on the roof surface then gluing it down and coating it with a contact adhesive. For pitched commercial roofs, our top material would be concrete tiles or metal. Concrete tiles will set you back anywhere between 40p and £2.90 per tile and they’re long-lasting and fire-resistant. However, they are heavy and can be susceptible to high winds. Metal roofs have been used for over 50 years and today’s modern systems are extremely strong and allow for structural or thermal movement. Aluminium roofs will cost between £40-75 per square metre, plus installation. These days, flat roofs are almost flat, but are usually built on a small slope so water can drain effectively.

An EDPM roof involves laying an EDPM rubber membrane on the roof surface then gluing it down and coating it with a contact adhesive. For pitched commercial roofs, our top material would be concrete or clay tiles. Concrete tiles will set you back anywhere between 40p and £2.90 per tile and they’re long-lasting and fire-resistant. However, they are heavy and can be susceptible to high winds. Clay tiles cost as little as 50p to £2 each and can last over 50 years, but they are heavy so if your commercial roof isn’t already, it will need to be reinforced.
