One of the primary reasons why people want to install flat roofs is because you can use the roof space as a living space. They are even more affordable than pitched roofs and less prone to moisture damage so you can expect them to last for years to come. But constructing a flat roof is not as easy as you think. Instead of trying a DIY roofing project, get in touch with experienced flat roofers.
Can I Use Timber For Flat Roofs?
Hundreds of flat roofs are constructed using timber every year. To make the boards waterproof, roofers lay them across the joists before covering them with a felt or rubber. The objective is to make the boards waterproof. You can ensure that the joints are strong enough to support the load of a flat roof by using tongue or grooved decking boards. One of the primary benefits of using timber when constructing flat roofs is that they require fewer repairs and maintenance.
When Should You Construct A Flat Roof?
Though pitched roofs are equally popular, you have to follow a minimum height requirement when constructing them. A very high pitched roof can block your neighbours’ view and prevent the entry of natural light. There are even a few situations when pitched roofs are not considered to be suitable for a home extension. The best alternative is to install a flat roof in your house. If your existing building has a flat roof, choose a similar design for the extension roof. A pitched roof will not only add more box gutters but even draining the roof will become a challenging task. Flat roofs have a very lean structure which allows water to drain easily. You can also connect it with the existing drainage system.
Why Are Sizes Of Joists So Important?
Flat roofs are a bit bulky because of the felt and boards used. The primary objective of the timber joists is to support the weight of the flat roof. Roofers engaged in flat roof construction ensure that the timber joists are strong enough for the roof. They consider numerous factors when calculating the height and weight of the joists. The calculation is then checked by a structural engineer. Using quality joists is an integral part of the Building Regulations. It is not only about the weight of the roof, the joists also have to stay prepared for additional loads like snow.
Choose The Right Type Of Flat Roof Construction
There are generally two types of flat roof construction. They are a warm roof and a cold roof. You can choose the ideal one after considering the owner’s requirements and the building regulations you have to follow regarding its insulation and heat loss. While a warm flat roof offers better insulation, the cold flat roof allows easy circulation of air between the joists. Whichever type of flat roof you are choosing, create a precise design and make sure it allows continuous airflow.
These being said, you now know how professionals construct flat roofs.
