Your flat roof protects your home or office from all conditions, but like all things, eventually they break down and needs replacing.
If you have had your flat roof for a while, it’s not uncommon to wonder, ‘When do I need to replace it?’, which is why we’re here to discuss when you actually need a new flat roof, as well as any signs you should be keeping an eye out for.
What Is a Flat Roof?
A flat roof is exactly what it sounds like, a flat roof. You can have variations of this style of roof, building them at angles, which can support water flow with heavy rain.
They are most commonly used on modern-styled homes, garages & outbuildings, as well as commercial buildings.
Despite what the name may suggest, flat roofs are not entirely flat. They are built with a slight slant to direct water towards gutters. If you’ve experienced persistent rainfall for 24 hours and water is still pooling on your roof, it’s worth having your flat roof checked.
What Materials Do Flat Roofs Use?
Flat roofs can be constructed with a variety of materials. Western Flat Roofing only use the highest quality materials and most efficient systems for your flat roof.
GRP Liquid
Suitable for a wide range of flat roof and surfacing applications, liquid-applied roofing systems are simple to install and host a wide range of benefits.
The liquid roofing is applied cold to create a seamless, waterproof membrane which is flexible with the movement of the building, providing a cost-effective way of waterproofing your new or existing roof.
Reinforced Bituminous Membrane (Felt)
Reinforced Bituminous Membrane, also known as Felt, is commonly used for flat roof waterproofing for both new-build and refurbishment projects.
The bitumen is combined with additives and a carrier such as fibreglass or polyester to produce a waterproof material that is easy to install, strong and low in cost.
Single Ply
Single ply is a flat polymer-based waterproofing system that is suitable for a range of projects, including new build and refurbishments.
Green Roof
Incorporating a green roof into your property is a great way to increase biodiversity and the ecological status of your building.
Made up of a layer of vegetation planted over a high-quality waterproofing system, Western Flat Roofing’s green roof system will provide you with outstanding results.
What is the Lifespan of a Flat Roof?
Like a lot of systems, the lifespan of a flat roof depends on the quality of materials used, as well as the expertise when installing the system.
For a standard Felt system, they can last between 15-25 years, depending on the quality of materials & installation.
When Would You Need To Replace Your Flat Roof?
Not every issue with your flat roof requires a full replacement, but certain issues can indicate that it’s time to switch out your old flat roof. These are the things you should be looking out for:
Exceeding Your Flat Roof’s Lifespan
If you have had your flat roof for between 15 and 25 years, it is certainly worthwhile having a specialist inspect it to ensure it is still performing as it should. Often, in this time frame, there will be more efficient systems to upgrade to.
Persistent and/or Recurring Leaks
Having a one-off leak can often be repaired by an expert. Recurring/persistent leaks however, will require a flat roof replacement entirely
Pooling Water
When water gathers on your roof, pooling can occur. This can happen due to structural damage or blocked drainage. If pooling is left for too long, it can cause leaks and dampness in your property. If you have suffered persistent rainfall (24-48 hours), it is worth checking your flat roof for pooling. If your roof is beginning to pool, call an expert to get it resolved quickly.
Visible Damage
After intense storms or extreme weather conditions, you will often see flat roofs suffer from fallen debris, such as branches.

Flat Roof Repair vs Replace
This is one of the most common questions we answer.
If your flat roof is damaged in a smaller, isolated area or has been recently installed, you will likely only require a repair.
If you have an older flat roof, installed 15+ years ago, or your flat roof has suffered significant damage, it will likely require a full replacement.

Is It Cheaper to Repair or Replace a Flat Roof?
The short answer here is yes – although this answer does not always tell a full story.
If your flat roof was installed poorly or with cheap materials, you may require multiple repairs, which may cost as much or more than a full replacement
With a full flat roof replacement from Western Flat Roofing, you will have the peace of mind that it has been installed expertly using resilient materials, which can last 15-25 years.
