Last Updated on: 27th March 2023, 10:05 am

Many homeowners mistakenly believe that the only costs associated with a roof are the initial expenses to install it. This common misconception can lead to overlooking the long-term financial commitment involved in owning and maintaining a roof. In reality, the costs associated with a roof are more akin to owning a car, where the initial purchase price is just the tip of the iceberg. Just as a new car requires routine maintenance, fuel, and insurance, a newly installed roof also demands ongoing attention and investment to ensure its longevity and performance.

Over time, a roof´s life cycle costs begin to grow, encompassing a wide range of expenses such as regular maintenance, repairs, energy efficiency improvements, and even environmental considerations like proper disposal and recycling of roofing materials. As ahomeowner, it is crucial to understand these life cycle costs to make well-rounded decisions that take into account both the short-term and long-term expenses of a flat roof. In this comprehensive article, we will delve into the various components of life cycle costs for flat roofs, from initial installation to ongoing care and maintenance, and even the impact on the environment. Our goal is to equip you with the knowledge necesary to make informed decisions that best suit your home and budget, ensuring you enjoy the benefits of a high-quality, durable, and cost-effective flat roof.

Oli Bate from the blog on Garland UK presents a compelling example demonstrating how a cheaper flat roof can actually become more expensive over a specific period when considering all life cycle costs. By comparing two different flat roofing systems, the analysis highlights the importance of factoring in not only the initial construction cost but also maintenance, operational, and renewal costs over the roof´s lifespan.

In the example, the High-Performance StressPly Flex Plus Built-Up Roofing System initially costs more than the Standard EPDM Single-Ply Roofing System. However, when considering the life cycle costs over a 30-year period, the High-Performance StressPly Flex Plus system proves to be more cost-effective. It has lower maintenance and operational costs, and its longer projected life eliminates the need for a renewal within the analysis period.

The following is anexplanation of a Life Cycle Cost (LCC) analysis for a 5,500 m² roofing project over a 30-yea r time frame. The analysis compares two roofing systems:a Garland UK 30 Year Guaranteed High-Performance StressPly Flex Plus built-up roofing system with a projected real-world life of 40-50 years, and a Standard EPDM Single-Ply Roofing System with a projected real-world life of 15 years.

For the High-Performance StressPly Flex Plus Built-Up Roofing System:

Construction Cost: £1,045,000
Renewal Cost: N/A (since the system has a longer projected life)
Operational Cost (Energy Savings): -£14,996 (indicating savings)
Maintenance Cost: £156,732
Total Expenditure throughout Analysis Period: £1,186,736
Net Present Value (NVP): £1,112,004

For the Minimum Standard EPDM Single-Ply Roofing System:

Construction Cost: £825,000
Renewal Cost: £1,552,276 (since the system has a shorter projected life)
Operational Cost (Energy Savings): -£13,996 (indicating savings)
Maintenance Cost: £214,041
Total Expenditure throughout Analysis Period: £2,577,321
Net Present Value (NVP): £1,706,920

In summary, the High-PerformanceStressPly Flex Plus Built-Up Roofing System has a higher initial construction cost but lower maintenance and ope rational costs, and does not require a renewal during the 30-year analysis period. This results in a lower total expenditure and a lower Net Present Value compared to the Standard EPDM Singl-ePly Roofing System, which has a lower initial construction cost but higher maintenance, operational, and renewal costs over the 30-year period.

So, let´s take a look at what´s included in the life cycle costs…
