HOW TO CHOOSE THE BEST MATERIAL FOR A FLAT ROOF
Covering a flat roof will be different from a traditional sloped roof for many reasons including the materials required. While a pitched roof can use overlapping shingles or tiles, this method is likely to lead to leaking for a roof without any slope. There are many different materials and methods to installing a flat roof, including rubber, thermoplastic, tar and gravel and modified bitumen, but which one is best?
Rubber membranes such as EPDM (ethylene propylene diene terpolymer) are often applied in giant custom sized sheets to fit your flat roof. This material is durable, and the custom size limits the areas where a leak could occur. This kind of rubber can be more expensive than other materials.
Thermoplastic materials such as PVC (polyvinyl chloride) or TPO (thermoplastic olefin) are durable options, due to heat-welded seams, and offer improved energy efficiency. However, roofs made of these materials can be difficult to repair.
Tips on Choosing the Right Roofing Material for Your Home
Consider Your Roof’s Structure
Every roofing material will perform well when installed in proper roof slopes. For instance, when it comes to flat roofs, metal is better than others since it sheds water and snow easily. Meanwhile, clay or concrete tile works best in steeper sloped roofs since they need reinforced roof framing to support their weight. In summary, the heavier the materials, the more structural modifications they require. This will cost you more on labor and materials.
Check Your Home’s Architectural Style
Pick a roofing material that historically matches your home’s architectural style. This way, you can improve your home’s personality and make it stand out. For example, a concrete roof tile works well with Tuscan, Mediterranean, and European homes due to its distinctive shape and texture. Meanwhile, a metal roof looks excellent in bungalow, ranch, and modern homes because of its sleek appearance.
Scrutinize the Material’s Features
Each roofing material has its own set of qualities, so choose the one that will meet your needs. Consider factors like performance, longevity, energy efficiency, affordability, and maintenance. Being clear about your priorities will help you make the right decision for your roof replacement.

Artificial or EPDM Rubber
This material has been among the most popular choices for flat roofs ever since it was first introduced in the U.K. EPDM, or ethylene propylene diene monomer, is a durable rubber roof that is often installed in one complete layer, doing away the need for joins that depend on size.
Installing a rubber roof ensures that you have not only an elastic, lightweight and tough roof, but also a roof engineered to withstand even the harshest of sunlight. Rubber or EPDM roofs are often glued down to the decking, but it can also be ballasted with stone or mechanically anchored with fasteners.
Torch on Felt
Flat roofs made of bitumen felt still have a bad reputation for becoming unreliable during the next few years, yet efforts had been made to improve them, making the roofing felts more flexible and durable. Generally, installation involves the application of a three-layer system, usually consisting of a vapour control layer, a 2 mm layer of reinforced felt, and a 4 mm layer of felt known as a cap sheet. A cap sheet can either be a plain black bitumen, making for a solar reflective paint finish, or a mineral fleck finish that comes with various colours.
People don’t usually go for fibreglass flat roofs, but what they don’t know is that with the only things they have to worry about are faulty installation and ignorance- which can easily be countered by hiring professionals. With proper installation, fibreglass roofs offer what the other two materials can do, and more.
How Often Should I Replace my Roof?
Each material has its own lifespan. EPDM roofs, with proper care, can last for over 30 years (though others claim they can last for 50). The same applies to a well-cared torch on felt roof while a fibreglass roof can last for 25 years. Whatever material your new flat roof will be made of, have a roofing expert in Surrey or Croydon, like those from Brunwin Professional Roofing Services, Ltd, install them to help you make the most out of your new roof.

Some roofing materials have more recycled content, which makes them less durable. You can check with the roof manufacturer to find out the composition of the roofing material before sealing your deal. Confirm with your roofer that the roofing material you are buying comes from the genuine manufacturer. You should ensure that your roofing material is recyclable once it reaches its lifetime. This way you will save some money for your next roofing project.

A single ply membrane is more pleasing to look at than EPDM rubber and offers very similar performance. Examples include PVC, TPO, TPE and PBE. The drawback to a single ply membrane is its price – it’s typically more expensive than the others listed.
