How Can You Replace Flat Roof?

When it comes time to replace your flat roof, there are a number of different factors to consider.

Here are some things that you should know about flat roof replacement, and important things to consider that will help you to go about having your flat roof replaced correctly. 

Roof Slope

This is to help prevent water from pooling and causing damage. Most common problems occur on flat roofs when the slope is not taken into account. Poor sloping leads to poor drainage, which leads to roof damage. It’s best to have a roof slope that’s a minimum of ¼” per foot. However, It would be the best idea if you can hire a roof professional in London for your roof maintenance.

Drainage

Roof drainage plays an important role in how a roof eliminates the water that collects on your flat roof. Even flat roofs that have been properly sloped, need somewhere for the water to go.

  • Internal Drains – Interior drains are commonly found in urban areas. They drain the water through the building and connect with the drainpipes into the storm drain or sewer pipes. 

You should take precautions with internal drains. In the event that the drains become clogged or frozen then break, you could end up with flooding or sewer discharge.

  • Scuppers – Scuppers are drains installed on the side of the roof that lets water free fall to the ground. If scuppers are wide enough, they won’t get clogged, and since they aren’t connected to pipes for indoor plumbing there are no risks associated with broken pipes.

  • Gutters and Downspouts – They are the traditional means of allowing water to drain.
