5 Common Problems With Commercial Flat Roofs

Designing and installing flat roofs isn’t a simple task, and the 5 most common problems that occur include:


Leakage Woes

Commercial flat roofs often face challenges with water pooling, inadequate drainage or ageing materials that lead to leaks.

116 Felt blistering

Material Deterioration

Weathering and exposure to the elements can cause roofing materials to deteriorate, affecting their structural integrity and performance.


Standing Water

An accumulation of standing water, AKA ponding, is a common problem in sagging roof sections or clogged drainage systems.


Flashing Failures

Leaks can occur when the thin piece of metal (flashing) used around chimneys, vents and edges to make things watertight is faulty or ages.

Causes of Condensation In a Roof (4)

Membrane Damage

The waterproof membrane is a crucial part of flat roofing systems, and if damage occurs, water may leak through.

Expert installation, proactive inspection and regular maintenance are key to addressing these issues and ensuring your commercial flat roof lasts for years to come.

Kevin Gibbs, Local Builder, Taunton Somerset

"In simple terms, Stephen knows his stuff!"

Recently I built five, four-bedroom homes in Surrey. While I’m experienced with refurbishing and extending properties, this was my first new build project, and the first time I had to meet standards set by the company that issues the building warranty. When I reached out for help with the flat roofs, I was looking for someone who understood what I was up against, and who could inspire confidence. Stephen was the first person to get back to me showing the right kind interest. I’d spoken to others; I just wasn’t getting what I needed in terms of advice. So I was happy when I found someone on the phone that seemed friendly, straight talking and well informed. I liked him right away. I had a thousand and one questions for Stephen, and I particularly want to thank him for his patience. The building was nearly at roof level when I called him in. I needed lots of answers, and I needed them fast. When I described my issues to him on the phone, he instantly knew what I was talking about. And if there was ever a time that he didn’t know straight away he’d find out and get back to me. So his responsiveness impressed me. Just to give you an example, I had my carpenters laying the wooden roof deck ready to hand over, when questions came up about the ventilation system. I was under pressure to get the roof on, and while it’s easy reading the book about the standard required for the warranty, it’s not one hundred percent clear. In this kind of situation you know he’s got the answers. “Don’t do it like that, this is how it needs to be done. Put this in, don’t do that. Simple.” Stephen is extremely professional, very helpful. He’s well informed of his facts and he knows what he’s talking about. To put it in its simplest terms, he knows his stuff.

"Paull has done numerous new build and replacement flat roofs for me. Everybody walks away happy."

I own a building company in the Cotswolds, established in 1881. We do the typical work of general builders, including house extensions and refurbishments. In the nine years or so that I’ve known Paull he’s done numerous flat roofs for us. We have a really good working relationship and have always been really satisfied with his service. He’s always coming up with things. What I mean is if you’ve got a problem, even if you think you know how to sort it out, he’ll normally find a better way to do it. Needless to say I don’t go to anybody else apart from Paull for flat roofing. Because I know that when he does it, it’ll be done right and everybody walks away happy.
