This week, we had a CPD seminar about – understanding low pitched roofs & the benefits of sub-roof systems, presented by Ari from Onduline Building Products Ltd. As chartered building surveyors at Focus Consulting, we understand the importance of staying up-to-date with industry advancements and regulatory changes. This seminar provided invaluable insights into the evolving standards and technologies in roofing, particularly concerning low pitched roofs and sub-roof systems.

The seminar delved into several critical aspects of roofing, starting with the significance of roof pitches. Ensuring the correct pitch for a building is crucial for its structural integrity and watertightness. With the introduction of BS 5534 and its amendments in 2015 and 2018, there are now stricter regulations to address extreme weather changes and align with European standards.

The Importance of Roof Pitches

The roof pitch plays a vital role in the overall performance and durability of a roof. A well-chosen pitch can enhance watertightness, prevent water ingress, and extend the roof’s lifespan. Furthermore, the seminar highlighted how the right pitch is essential not only for functional reasons but also for maximising living space and aesthetic appeal.

Seminar Insights

The seminar focused on several crucial aspects of low-pitched roofs and sub-roof systems. Here are some key points discussed:

Understanding Roof Pitches: The seminar began by explaining the variety of roof pitches and why they differ depending on the type and purpose of a building. It highlighted how different pitches can influence the overall aesthetics, functionality, and weather resistance of a roof.

Pros and Cons of Different Roof Pitches: We learned about the advantages and disadvantages of various roof pitches. For instance, steep roofs are excellent for shedding snow and water quickly; however, they can be more expensive and complex to construct. Conversely, low-pitched roofs are easier to build and can offer more usable space under the roof, but they require careful waterproofing.

When to Use Different Roof Pitches: The seminar provided guidance on selecting the appropriate roof pitch for specific situations. Factors such as climatic conditions, building type, and architectural style all play a role in this decision-making process.

Benefits of Low-Pitch Roofs for End-Users: One of the key points discussed was how low-pitched roofs can benefit end-users. These roofs can create more living space, reduce construction costs, and offer a modern aesthetic. However, they require effective waterproofing solutions to prevent water ingress.

Understanding Sub-Roof Systems: The concept of sub-roof systems was thoroughly explored. A sub-roof acts as a secondary barrier against water penetration, ensuring the primary roof covering remains effective even in extreme weather conditions. The seminar emphasised when and how to use these systems to enhance roof durability and performance.

Low Pitched Roofs & The Benefits of Sub-Roof Systems

In conclusion, the CPD seminar by Onduline Building Products has equipped us with a deeper understanding of low-pitched roofs and the importance of sub-roof systems. These insights are invaluable as we continue to advise our clients on the best roofing solutions to meet their specific needs, ensuring both functionality and aesthetic appeal.
