Guttering in Greater London

• A sturdy ladder
• Gloves and safety goggles
• A hammer and nails to secure your fascia so it doesn’t fall down mid-replacement
• A hacksaw – this will cut through uPVC guttering – just make sure you leave a margin of error with every cut you make
• Cable ties or rope to secure the existing gutters while you dismantle them, so they don’t fall off
• All the right fixings and brackets to secure the guttering
• An electric drill and/or screwdrivers

1. Add a gutter bracket to the top of the fascia board at the opposite end to the stop-end outlet, if you have one. Then tie a piece of string around the base of the bracket.
2. You’ll need to place the gutter outlet accurately over the drain. Hold a plumb line against the fascia directly over the drain, and mark that position with a pencil. Following the manufacturer’s advice on the number of screws to use, fit the gutter outlet no more than 50mm below the level of the roof tiles.
3. Stretch the piece of string you tied on the bracket along the fascia board, and tie it to the outlet. Make sure you check with a spirit level that the string slopes towards the outlet.
4. Mark the positions of the other brackets. They should be no more than 800mm apart, or 600mm if your roof is very steep. They also shouldn’t be any more than 150mm from a joint or fitting. Then fit the rest of the brackets.
5. Fit a stop-end to the first length of gutter and clip it into position on the brackets. At the other end, fit a union piece and screw it into the fascia.
6. Then fit the next length of gutter into it, and the next until you’re finished. Cut the last one to fit using your hacksaw before attaching a stop-end. Then make sure all the joints line up with the insertion depth marks on the fittings. Then you’re done!

In the UK, gutters are normally made from uPVC. It’s a hardy plastic that won’t rot, warp or tarnish very easily, which is why it’s so popular. It’s the same material that’s used for most homes’ windows these days; they don’t have to be the standard white as they can be made into a range of colours. Expect to pay an average of £500 for the supply and installation of uPVC guttering, and more if you require scaffolding.

Other materials that are popular for gutters include copper, aluminium and cast iron. These are much more expensive – you might be looking at around £1500 or more for the supply and installation – but they give a more polished look and are often used on period properties or those in a conservation area. If you're considering these types of gutters, make sure you get a few quotes from different roofline companies so you can compare the different materials.

In the past, gutters were made from wood, asbestos concrete or stone. They were often lined with lead to stop the water from seeping through. When it was discovered that asbestos was seriously harmful, it of course stopped being used. Wood was prone to rotting, even with lead lining, and stone is heavy and expensive. So when uPVC came along, it became an affordable and easy material to use for gutters so homeowners could be confident that rainwater will be kept away from the foundations of their properties. It’s important to keep gutters clear from leaves and debris, because if they become blocked, they can make water to fall against your property’s walls, causing damp.

You don’t always need to replace your gutters with your roof. Often people think that it’s a requirement, or simply the best thing to do, but it’s not always necessary. The reason why people think it’s required is because to re-roof a home, the guttering often needs to be removed and put back on.

If the time has come to replace your roof, then the chances are that your guttering is pretty old too. When you start to get quotes for your roof replacement, ask the roofer to take a look at your guttering as well. If there are signs of peeling, rust, cracks or sagging, then it makes sense to replace your gutters with your roof. If you get them done at the same time, you’ll save money labour costs, which is the reason why most homeowners do it.

Another reason to replace your gutters with your roof is the risk of damage. Re-roofing is a significant project, so the guttering needs to come off most of the time – running the risk of brackets and pipes getting damaged in the process. So if your guttering is still looking good right now but you think it might need replacing in a couple of years, it might be worth just doing it at the same time as your roof to save you money and the stress if damage does occur.

However, if your guttering has only recently been replaced, then there’s no need to replace it again with your roof. But because it needs to come off, make sure you speak to the roofing company about keeping it safe and doing their best to avoid damage. It’s also worse ensuring that they have the correct insurance to cover you both in case your guttering does get damaged during your roof replacement.
