Most homeowners don’t worry about their roof until it leaks. While overall maintenance is vital to ensure maximum roof performance, waterproofing is the most crucial part of maintaining a flat roof. Unfortunately, not many people know how to waterproof a flat roof.
Sloped roofs allow water to slide off easily into the gutters. Flat roofs have a shallow slope that directs water, but when leaves, sticks, and other debris collect on them, the water often has nowhere to go.
Read on to learn how to waterproof a flat roof and why it’s important.
Choosing a Waterproofing Method
Industry professionals use multiple flat roof waterproofing solutions. The main factors to consider for flat roof waterproofing are:
- Environment: Think about the temperatures and air quality in your area.
- Structure and roof size: Different methods work better for residential and commercial roofs.
- Budget: Some waterproofing solutions are more costly than others.
While someone may recommend a waterproofing technique that worked for them, it may not be the best option for you. As such, consider these factors carefully before making a decision.
How to Waterproof a Flat Roof
The three most common flat roof waterproofing options are:
Reinforced Bitumen Membranes (RBM)
This process begins by laying two or three membrane layers on the roof surface and bonding them with hot bitumen. Once combined with a polyester carrier, it creates a waterproof material. This layer covers the insulation for warm flat roofs and covers the structural deck for cold ones.
You can attach the roof membrane using several methods, such as:
- Rolling the membrane over hot bitumen
- Cold adhesive
- Gas torch
This option uses a coating to seal the roof and effectively weatherproof it. It works for all types of roofs but is most commonly used for flat roofs. Additionally, the coating lasts between 20 and 40 years, depending on the quality of the product, maintenance, and installation.
The most popular liquid waterproofing options include the following:
- Fiberglass liquid
- Liquid fleece membrane
- Glass-reinforced plastic
If you want to know how to waterproof a flat roof that is larger than others, single-ply membranes are best for commercial buildings and large residential roofs. The membrane sheets can cover the entire roof, and you can attach them to your roof in numerous ways, including
- Adhesion: Polyurethane adhesives secure the membrane and insulation.
- Fastening: This attaches the membrane to the roof deck with plastic screws.
- Ballasting: This gravel top coat protects the membrane from UV rays while holding it in place.
