Why Extend Your Roof Before Installing a Rubber Roof?

So, why bother with extending your roof in the first place? Extending your roof before adding a rubber roof provides numerous benefits that contribute to the overall integrity and lifespan of your roofing system. Think of it as laying a solid foundation for your new roof – it's that important! Let’s break down the key reasons:

  • Improved Drainage: Proper drainage is paramount for any roofing system, and rubber roofs are no exception. By extending your roof, you can create a more effective slope that allows rainwater to flow freely away from your building. This prevents water from pooling on the roof, which can lead to leaks, water damage, and even structural issues over time. Nobody wants a leaky roof, right? An extended roof can significantly minimize these risks. Improved drainage is achieved by carefully designing the extension to ensure a consistent and adequate slope. This might involve adding additional layers of sheathing or modifying the existing roof structure to achieve the desired pitch. The goal is to create a smooth, uninterrupted path for water to travel from the roof to the gutters.

  • Enhanced Weather Protection: A roof extension acts as an additional barrier against the elements, protecting your building from harsh weather conditions such as heavy rain, snow, and strong winds. This is especially crucial in areas with severe weather patterns. Think of it as an extra layer of armor for your home! An extended roof can provide significant protection against wind uplift, preventing the rubber membrane from being damaged or torn off during storms. It also helps to minimize the impact of hail and other debris, reducing the risk of punctures and other damage to the roofing material. By creating an overhang, the extension also shields the walls of your building from direct exposure to rain and sun, which can help to prevent siding damage and fading.
