What is the Best Flat Roof?
When it comes to determining the best waterproof flat roof, there isn’t a one-size-fits-all answer. Each roofing option has its own strengths and weaknesses. To help answer this question, we’ve compiled a list of key benefits and limitations for some of the most popular flat roofing systems.
This option is typically considered the best flat roof waterproofing system for ease of installation and durability. EPDM rubber roofing comes with a long guarantee, is low-maintenance, and can be purchased in one sheet from some of the best flat roofing companies. The downside is that it is not suitable for foot traffic, and due to the membrane’s thinness, it can be easily punctured.
GRP Fiberglass Roofing
GRP fiberglass is tough and impact-resistant, making it suitable for foot traffic. It gives a sleek, clean finish, but installation can be tricky, and over time, it is prone to cracking. Despite its toughness, these cracks can eventually undermine the waterproof roofing material, reducing its lifespan.
Cold-Liquid Repair Solutions
Cold-liquid systems provide instant waterproof protection and can be applied to most flat roof surfaces—even in damp conditions. However, unless installed by professionals, this option tends to be a short-term fix. This type of best flat roof waterproofing might require several coats to become fully waterproof.
Roofing Flat Roof Replacement Questions
How do flat roofs drain?
Flat roofs are not entirely flat. They should have a slope of at least ¼ inch per foot to ensure proper drainage. Water is directed to strategically placed drains or outlets, preventing ponding on the roof.
Should water sit on a flat roof?
In the short term, small amounts of water might collect on a flat roof. However, prolonged ponding can damage the waterproof roofing material, especially in colder months when water freezes. Over time, stagnant water can cause silt buildup and membrane damage. Some flat roofs, particularly those with EPDM membranes, may see bubbles or small pools of water due to their installation methods.
How do you stop a flat roof from leaking?
Stopping a leak depends on the type of best flat roof waterproofing system in place. Common areas to check for leaks include:
- Cracks and splits
- Joints and overlaps
- Around vents or roof lights
- Screw or bolt holes
- Lead flashings
- Parapet walls
For smaller domestic leaks, a flexible waterproof coating might be enough to solve the issue. For more significant problems, it’s best to contact the best flat roofing company for professional advice. If your roof is under warranty, check whether the leak repair is covered.
Are Flat Roofs Bad?
Flat roofs, like any other roofing system, have their place. If installed and maintained properly, they can last for years without major issues. However, flat roofs generally require more maintenance, especially if the roof is frequently walked on. For roofs that remain undisturbed, a well-installed flat roof can provide a long-lasting and trouble-free solution.
How Long Do Flat Roofs Last?
A flat roof, when installed by professionals using the best waterproof flat roofs systems, should last a minimum of 20 years. Some materials, like EPDM, can last up to 50 years. Regular maintenance and repairs can further extend a flat roof’s lifespan.
What Are the Advantages of a Flat Roof?
Flat roofs offer several advantages, including quicker installation and potentially lower costs over their lifespan. They can increase outdoor usable space, and with the growing trend of green roofing, a flat roof can also be converted into a relaxing outdoor area. Additionally, using the best waterproof flat roofs ensures long-lasting protection from the elements.
How Often Should You Replace a Flat Roof?
How often a flat roof needs replacement depends on the materials used. Systems like Prelasti EPDM or Protan PVC offer guarantees of at least 20 years, meaning you won’t need to think about replacement for decades. However, older materials like felt may require more frequent monitoring and eventual replacement if they stop performing effectively. If you’re unsure about the lifespan or condition of your flat roof, consulting with the best flat roofing company is a smart step.
