How much does a new roof for a terraced house actually cost?

It’s the question I get asked every single week in Brighton, Hove, and Worthing. You type it into Google and get a dozen different answers, most of them useless. The truth is, anyone giving you a fixed price online without seeing your roof is just guessing. But I can give you the straight facts on what actually goes into the price, based on 18 years of being on these roofs myself.

For a standard 2/3-bedroom terraced house in Sussex, you should budget anywhere from £7,000 to £14,000+ (VAT included) for a full replacement. That’s a big range, I know. So let’s break down exactly where your money goes.

What are the biggest factors that change the price?

The final quote isn’t just about tiles. It’s a combination of several critical things. Here’s what I look at when I’m pricing a job.

1. The Scaffolding and Access

This is a big one, especially with the tightly packed terraced houses in Brighton. Getting safe access to your roof is non-negotiable and can easily account for £1,500 – £3,000 of the total cost. If access is difficult (over a conservatory, narrow alleyway), the price goes up.

2. Your Choice of Roof Covering

What your roof is made of is the next biggest variable. You’ve got a few main choices for a pitched roof:

  • Concrete Tiles: The cheapest option. They do the job, but they’re heavy, fade over time, and don’t have the character of slate or clay.
  • Clay Tiles: A classic, traditional look. More expensive than concrete but they last longer and look fantastic on period properties in the Hove area.
  • Natural Slate: The premium choice. A good quality Spanish slate roof will last a lifetime (80+ years) and looks sharp. It’s the most expensive material, but it’s a true long-term investment.

I can walk you through the pros and cons of each when I see your property. You can read more about my approach to pitched roof replacements in Brighton here.

3. The ‘Extras’ That Aren’t Really Extras

This is where cheap quotes fall apart. A proper roof replacement isn’t just about the tiles. It’s a full system that has to be done right. These are essential parts of the job that must be factored in:

  • Leadwork: The flashing around your chimney, in the valleys, and against adjoining walls is crucial for waterproofing. Skimping on this is asking for trouble. Good leadwork takes skill and time. If you have a leaking chimney, it’s often the lead flashing that has failed.
  • Insulation: Building regulations now require a certain level of insulation. If your loft isn’t up to spec, we’ll need to install or upgrade it when we replace the roof. This adds to the cost but saves you money on heating bills.
  • Fascias, Soffits & Guttering: If your roof is old, chances are the timber fascias are rotten and the guttering is failing. It makes zero sense to put a brand new roof over rotting timber boards. I always recommend replacing them with low-maintenance uPVC. It’s much cheaper to do it while the scaffolding is up. Check out the details on fascia and soffit replacement.
  • Structural Repairs: I can’t see the state of your roof timbers (rafters) until the old tiles are off. If we find any rotten or damaged wood, it has to be replaced. This is an unknown variable until we start, but I always warn my clients about the possibility.

Do I really need a full replacement if I only have a small leak?

Sometimes, no. If your roof is generally in good condition and you have a single, isolated problem like a slipped slate or a failed bit of flashing, a targeted repair can be perfectly fine. A small, persistent drip can often be solved without stripping the whole roof. If you’re in that situation, you might need my emergency roof leak repair service.

However, be brutally honest with yourself. If your roof is over 50-60 years old, the tiles are brittle, and you’re constantly paying for small patches, you’re just throwing good money after bad. A full replacement gives you peace of mind and a guarantee that lasts for decades, not just until the next storm.

How do I get an accurate, fixed price?

Stop relying on online calculators. The only way to get a real price is to have an experienced roofer get up there and have a proper look. I do this for free. I’ll come to your home in Brighton, Worthing, or anywhere in Sussex, assess the roof’s condition, measure up, and discuss the material options with you face-to-face.

From there, I’ll give you a detailed, fixed-price quote. The price I give you is the price you pay. No hidden extras. You’ll also get access to my client portal with daily photo updates of the work, so you can see the progress for yourself. The first step is to book a free roof inspection on my website.
