Often times, the roofs you see that look flat actually have a slight slope. A low slope roof ensures proper drainage. Otherwise, water and snow would sit on the roof and lead to leaks and other forms of damage. If you have ever considered this roof type, you probably have questions about how well it compares to other options. Here are a few basics you should consider.
People often use metal roofs to create a low slope. This roofing material is relatively inexpensive, easy to replace and extremely lightweight. However, most roofs with a low slope use the same material as flat roofs. Subsequently, rubber roofs are likely to be the most common. Rolled roofing with a mineral surface, concrete and vinyl single-ply are other options. Consider the load-bearing rating of the building structure when making a choice.
Most people considering a low slope roof are doing so as an alternative to flat roofs. So, is it better than the traditional option? As explained earlier, flat roofs suffer from poor drainage. When water gathers on the roof, these pools of water can cause the roof to sag over time. This is what leads to leaks. It also explains much of why flat roofs are so expensive to maintain. They do, however, require less material during the initial installation due to working with a smaller surface area.
Ideally, you should schedule roof inspections at least twice per year. This is especially important if you live in the Snow Belt as snow loads can cause damage during the winter to any roof. During inspections, contractors will let you know if there is any need for repairs. Only light repairs tend to be needed at these times.
Homeowners often consider flat roofs for contemporary homes, gardens and detached garages. A low slope roof offers a much more cost-effective and longer-lasting alternative.
