Factor In the Material – The materials used to make a flat roof play a large part in determining its lifespan. A multi-layer built-up roof consisting of waterproof material, hot tar and gravel can last for 15 to 20 years. Roofs consisting of three to five layers of modified bitumen have a slightly shorter average lifespan of 10 to 15 years.
These materials are heavy and may not be the best choice for every building. Lightweight single-ply roofing can last for as long or longer than layered roofs depending on the properties of the material, the design of the roof and reliance on commercial roof repair. EPDM and TPO roofing generally last anywhere from 10 to 20 years, while TPO roofs have stronger seams than EPDM roofing.
With proper maintenance, a PVC roof can last up to 30 years.

Why Flat Roofs Are a Good Choice for Commercial Buildings Flat roofing is the typical roofing found on commercial buildings, such as shopping malls, warehouses, large department stores, condos, apartment buildings and manufacturing plants. This is mainly due to the considerably larger size of commercial buildings as compared to residential structures.

What maintenance does a flat roof require?
Protect and Maintain your Flat Roof Flat roofs, while an attractive feature on a property, require more maintenance than angled roofs. Hence premiums tend to be higher than those for apex roofed properties. Fortunately, there are a few simple ways by which you can extend the life of your flat roof, and in doing so, potentially limit the restrictions applying to your policy.
Perform Yearly Inspections Although not a condition of our policy, flat roofs should be inspected every year.

Check For Signs of Roof Drainage Issues Ensuring that your roof can drain properly is one of the most important things to do. If water cannot drain off the roof, it can cause ponding and blisters. Ponding is when water accumulates on areas of the roof; it can cause leaking and even roof failure.
It’s easy to spot as there will either be puddles of water on the roof or if there are dry conditions, a lowered area ringed by dirt. Blisters occur when water gets between the layers of the roof. To prevent this from occurring, make sure your drainage system is clear.
- If your property has trees growing nearby, it will need to be checked more frequently as leaves and debris can clog gutters and drains It should also be checked after heavy snowfalls, especially during a thaw, as snow and ice can cause blockages and damage.
- Regularly Check for Cracks & Punctures Flat properties should be regularly checked for cracks and punctures in the roof surface.
If these occur, like any other issues, they should be addressed before they worsen. Applying reflective aluminium paint can prevent or slow down sunlight from breaking down the roofing material, extending the life of your roof. Take Out Flat Roof Insurance It is also advisable to take out a flat roof insurance policy to make sure that, should something go wrong, you are properly covered.
