How to Drain Water from a Flat Roof

A flat roof is a popular choice for commercial and residential buildings, as it offers a practical and modern solution. However, with its minimal slope, it can create drainage problems. Flat roofs can accumulate water, which can lead to leaks, water damage, and even structural damage if not properly maintained. Here are some steps on how to drain water from a flat roof:

  1. Inspect the Roof

Before you begin draining water, inspect your roof for any damage. Check for cracks, holes, and any signs of wear and tear. It is crucial to repair any damage before draining the water to prevent further damage.

  1. Locate the Drain

Locate the drain or scupper, which is the outlet for water to leave the roof. The drain is usually located near the edge of the roof or at the lowest point. If you cannot locate the drain, contact a professional to assist you.

  1. Clear Debris

Clear any debris, such as leaves or branches, that may be blocking the drain. This can cause water to accumulate and damage the roof.

  1. Use a Squeegee

Use a squeegee to push water towards the drain. Start at the highest point of the roof and work your way towards the drain. Be cautious not to push too hard, as it can damage the roof’s surface.

  1. Install a Drain Cover

Install a drain cover to prevent debris from blocking the drain. This can save you time and money in the long run.

  1. Install a Scupper

If your flat roof does not have a drain, install a scupper. A scupper is an opening in the wall that allows water to drain from the roof. It is usually located near the roof’s lowest point.

  1. Install a Tapered Insulation System

Consider installing a tapered insulation system if your flat roof does not have enough slope. A tapered insulation system is designed to create slope and direct water towards the drain or scupper.

  1. Hire a Professional

If you are not comfortable with draining water from your flat roof or encounter any difficulties, it is best to hire a professional. They have the necessary expertise and equipment to perform the job safely and effectively.

In conclusion, draining water from a flat roof is essential to prevent water damage and structural damage. By inspecting the roof, locating the drain, clearing debris, using a squeegee, installing a drain cover or scupper, installing a tapered insulation system, and hiring a professional when necessary, you can ensure your flat roof functions effectively and efficiently.
