How To Slope A Flat Roof For Drainage In Cumbria

If you're a property owner in Cumbria with a flat roof, you're probably aware of the challenges that come with it. One of the most significant challenges is ensuring proper drainage to prevent water damage, which is common in this region of North West England. In this article, we will discuss some essential tips and techniques for sloping a flat roof for drainage in Cumbria.

Understanding the importance of drainage

Drainage is crucial for any building, but it becomes even more critical in Cumbria due to the high rainfall levels. If your flat roof does not have adequate drainage, water will pool on the surface, and eventually, this water will find its way into your building through leaks and cracks.

Without proper drainage, these leaks can lead to major structural damage, mold growth, and health hazards. Inadequate drainage can also lead to the rapid deterioration of the roofing material. So, it is essential to ensure that your flat roof has proper drainage to avoid these negative consequences.

Common issues with flat roofs in Cumbria

Flat roofs have a reputation for being prone to various issues, including leaks, punctures, and water pooling. These problems occur for several reasons, the most common being inappropriate slope and inadequate drainage systems.

Water pooling on a flat roof occurs when there is no way for you to remove the water through the available drainage system. In Cumbria, these poolings often turn to bigger issues, as our location receives high levels of rainfall throughout the year. Water can seep under flashing, into roofing materials and make its way into the buildings.

How to slope a flat roof for drainage

When it comes to flat roofs, the main goal is to create a slight gradient that allows water to run off quickly and smoothly. Sloping your flat roof doesn't have to be a complex process; there are several ways to achieve it.

Method 1: Built-in slope

The most common way to add slope to a flat roof is through the built-in slope method. This method involves constructing the roof with a slope from the beginning. The roof is installed on a frame that has a slight angle. This ensures that water flows in the desired direction, and the roof is built with a slight slope, which ensures that water drains efficiently.

The best angle to slope a flat roof is 1 in 80, although this may vary depending on the roofing materials used. The slope should be enough to ensure that water drains quickly and easily.

Method 2: Tapered insulation

Tapered insulation is another popular method of sloping flat roofs. This approach involves using specially designed insulation boards that are thicker on one end and thinner on the other. The insulation is installed in such a way that it creates a gradual slope.

This method is visually appealing and is an ideal solution for flat roofs that have poor drainage. In terms of functionality, tapered insulation systems are known to offer superior drainage and better insulation than traditional flat roof systems.

Method 3: Relying on gravity

If you're looking for a simple way to add slope to your flat roof, you can rely on gravity. This method involves adding additional layers to the low areas of your flat roof. These added layers will create a natural slope as water will flow towards the added layers, which will be at a higher level than the rest of the roof.

While this approach is the least expensive, it may not be the most effective in terms of drainage quality, especially if the roof slope is too slight or too steep.
