Frequently Asked Questions (FAQs)
Which Type of Flat Roof is Best?
When choosing the best flat roof for your property, several factors come into play, including budget, longevity, and the specific demands of your building. The three most popular materials for flat roofs are:
- EPDM (Rubber Membrane): EPDM is a highly durable synthetic rubber membrane that is ideal for both residential and commercial properties. It’s known for being weather-resistant, energy-efficient, and capable of withstanding extreme temperatures. It’s a great choice for those seeking a cost-effective option that will last 25 to 30 years with minimal maintenance.
- GRP (Glass Reinforced Plastic): GRP roofs are known for their strength and durability, especially in areas where heavy foot traffic is expected. This material forms a seamless, waterproof barrier that’s resistant to UV damage, making it a great option for properties in sunny climates. While slightly more expensive than EPDM, GRP roofs can last up to 40 years with proper maintenance.
- Bitumen (Torch-On): Bitumen is a classic and affordable choice for flat roofs, providing strong waterproofing and durability. It’s typically applied in multiple layers, making it highly resistant to leaks. However, bitumen roofs generally have a shorter lifespan than EPDM or GRP, lasting around 15 to 20 years, and may require more maintenance to keep them in top condition.
We’ll help assess your needs and guide you toward the best roofing material for your home or business, taking into account factors like durability, maintenance needs, and budget.
What is the Life Expectancy of a Flat Roof?
The life expectancy of a flat roof largely depends on the material you choose and how well the roof is maintained over time. On average, flat roofs last as follows:
- EPDM: This synthetic rubber membrane is known for its longevity, often lasting between 25 to 30 years when properly installed and maintained. Its resistance to UV rays, extreme temperatures, and weather conditions makes it a reliable choice for many homeowners and businesses.
- GRP: With proper care, GRP roofs can last an impressive 40 years or more. This material is highly durable, forming a seamless surface that resists leaks and damage, even in harsh weather conditions.
- Bitumen: While affordable, bitumen roofs have a shorter lifespan compared to EPDM and GRP, typically lasting around 15 to 20 years. Bitumen may require more frequent repairs and maintenance, especially in areas where the weather is harsh or where the roof experiences heavy use.
Regular inspections can help extend the lifespan of your flat roof. During these inspections, we check for potential issues such as cracking, blistering, and wear around seams. Prompt repairs can also ensure that your roof continues to perform effectively, even as it ages.
What is the Most Affordable Roofing Option for a Flat Roof?
When it comes to cost, Bitumen (Torch-On) roofing is generally the most affordable option for flat roofs. This material is relatively inexpensive, easy to install, and provides a good level of waterproofing. Bitumen roofs are typically applied in multiple layers, which makes them a practical and durable option for budget-conscious homeowners or business owners. However, while it may save money initially, bitumen roofs typically have a shorter lifespan than options like EPDM or GRP, so they may require more frequent repairs or a replacement down the road.
While the upfront cost is a major consideration, it’s important to think about long-term durability and maintenance when choosing your roofing material. We’re here to help guide you to the most cost-effective solution that will also stand the test of time.
What is the Longest Lasting Flat Roof Material?
For longevity, GRP (Glass Reinforced Plastic) is considered the best option. GRP roofs are incredibly durable and are designed to last 40 years or more, making them the longest-lasting flat roof material. This material is resistant to UV damage, extreme weather conditions, and even heavy foot traffic, which makes it a great choice for high-demand environments. GRP forms a seamless membrane, eliminating potential weak spots that could lead to leaks or other issues. While the initial cost of installation can be higher than other materials, the long-term durability of GRP makes it an excellent investment for your flat roof.
Choosing the right material is an important decision, and we’re here to help you assess the specific needs of your building so you can make an informed choice that offers the best value over time.

CRS came exactly when they said they would and offered a competitive price. The work started and finished on time, and I was kept informed throughout. An unexpected issue came up once the old roof was off, and they resolved it at no extra cost. Highly recommend.
