So, you need to find a flat roof company in Brighton or Worthing? Good luck.

I’m not trying to be cynical. I’ve just spent the last 18 years fixing the mess left behind by ‘roofers’ who shouldn’t be allowed near a ladder, let alone your home. Finding a good specialist is tough. Most general builders will say they can do a flat roof, but there’s a massive difference between slapping on a bit of felt and installing a high-performance system that will last for decades. I’m going to tell you exactly what I’d look for if I were in your shoes.

What’s the very first thing I should check?

Forget slick websites and fancy vans for a minute. The first thing you need to know is if they are a genuine flat roof specialist. Ask them directly: ‘What systems do you install?’ If they can’t confidently talk you through the pros and cons of GRP (fibreglass), EPDM (rubber), and high-performance torch-on felt, they’re likely a generalist. A real specialist knows which system suits which job. For example, a simple specialist garage flat roof might have different requirements to a complex extension with skylights. Don’t be afraid to push for details.

How do I know if their quote is fair?

A quote on the back of a business card is a massive red flag. A proper quote is detailed, itemised, and, most importantly, fixed. It should break down the cost of materials, labour, and waste disposal. I provide fixed-price quotes because you should know exactly what you’re paying from the start, with no nasty surprises. Also, a proper roofer will insist on seeing the roof first. A quote given over the phone, sight unseen, is just a guess. If you’re unsure what your roof needs, the first step should always be to book a proper, free roof inspection to get a true assessment.

What are the non-negotiable questions I MUST ask?

Right, get a pen. When a roofer comes to your home in Hove or Brighton, you need to ask these questions point-blank. Their answers will tell you everything.

  • Can I see your Public Liability Insurance? If they hesitate, show them the door. End of story.
  • What guarantee do you offer? Ask if it’s just a manufacturer’s warranty or if it’s their own workmanship guarantee, backed by insurance. There’s a big difference.
  • Will you be using subcontractors? You need to know who is actually going to be on your property. I do all the work myself, so the buck stops with me.
  • How will you keep me updated? Vague promises aren’t good enough. I give my clients access to a portal with daily photo logs so they can see the progress for themselves, even if they’re at work. It’s about transparency.

What are the biggest red flags to watch out for?

I see these all the time, and they usually lead to a frantic call for an urgent leak repair a few months down the line. Watch out for:

  • ‘Can we have the money in cash?’ This is the oldest trick in the book. It often means no paper trail, no VAT receipt, and no comeback for you when it leaks. Avoid.
  • Huge upfront deposits. A small deposit for materials can be normal, but a demand for 50% or more before any work has started is a major warning sign.
  • Pressure to sign immediately. ‘This price is only for today!’ is a classic pressure tactic. A reputable roofer will give you a written quote that’s valid for a reasonable period.

How do I know if I need a repair or a whole new roof?

This is the million-dollar question. Sometimes, a small repair is all that’s needed. Other times, a repair is just throwing good money after bad. It depends on the age of the roof, the type of material, and the extent of the damage (like blistering, major cracks, or extensive water pooling). A good roofer will explain your options honestly. They’ll show you photos of the problem areas and explain why they are recommending a specific course of action, whether it’s a simple patch or a full flat roof repair and replacement. The goal is to give you a long-term solution, not just a quick fix that fails next winter. It’s the same principle for any specialist work, like properly waterproofing a balcony or roof terrace; the diagnosis has to be right first.

Ultimately, choosing the right company comes down to doing your homework and trusting your gut. Find someone who specialises in flat roofs, is transparent about their process, and can answer your questions without getting defensive. Your roof is what keeps your home safe and dry – it’s worth the effort to get it right.
