How much a flat roof costs to repair depends on a few factors. Is your flat roof on a garage or an extension? What is the flat roof made from? It’s always best to get a few quotes to compare prices, but we’ll give you a rough idea here. If your flat roof was installed in the 1990s or earlier, it’s likely that you’ll see some leaks or damage soon. Felt flat roofs used to be installed completely flat, which meant that water couldn’t run off. That means that water pools and can create moss and damp. Sun exposure can also damage the felt, causing damage and eventually holes that lead to leaks. If you’re lucky enough to have got away with just needing a flat roof repair, this should set you back an average of £100 per square metre. If your roof is sagging due to the weight of it putting pressure on the timber frame, you might need additional joists – which could cost anywhere between £1,000 and £2,000, depending on how many you need. But if the problem is due to the internal part of the roof system becoming waterlogged, you could be looking at over £5,000. If your roof is severely leaking or the timber joists are rotting, it might be more cost effective to replace your flat roof. If you keep forking out for repairs, it will eventually be cheaper just to replace the whole thing, which could cost around £2,000.

If your existing roof is still in good condition but the membrane is getting old, it’s often not worth exposing the structure to the weather whilst the contractor strips off the old membranes. The contractor will leave them in place to act as a base layer for a new roofing system. As long as there are no other problems with your roof, then overlaying is a good way to replace your flat roof.If you have any more questions about flat roofing that aren’t listed here, fill out our form to ask a contractor.

How Much To Replace A Flat Roof

There’s no straight answer to this question. However, the average cost lies within the range of £1000 to £5000. This range may look too wide but the price is greatly influenced by a number of factors which is capable of making the price increase or decrease. Some of the factors affecting the cost of flat roof coverings and replacement include: the type of flat roofing system and materials you want, the area size of the flat roof in M2, the project’s location, the roofing company to be used, the ease at which to reach the roof, cost of removing the old flat roof as well as cost of removing the other waste.

Although there are many factors to be put into consideration but the most crucial factor is the size of the house or the area size of the flat roof in M2. for instance, a one bedroom apartment’s flat roof will have a price between £1500 to £3000. This is, however, with the assumption that the flat roof is going to be used as the main roof of the house. But if you’re only using it for a section of the house like your garage, the price could range between £700 to £1000

There four commonly used types of flat roof materials which includes fibreglass, felt, rubber and lead. If you need a felt roof, for example, the price is between £40 to £70 per m2. And in the same tone, a metal roof will generally cost more than a a flat roof made from rubber.

Another important factor we’ll discuss is the labour or the roofing company to be used. Different roofing companies will charge different prices. As a result, you should carefully compare the prices of the companies in order to get a great deal.

1. Tube size: Small areas or stairways can gain from a 10-inch size tube, whilst bigger rooms will require a bigger tube. The higher television size, the greater the price.
2. Kind of tunnel and also roof type: You can pick from stiff or flexible tunnels and also domed or flat roofing system panels. Each choice will have a different price.
3. Place: Where you stay in the country will certainly impact the price of your sun tunnel installation. Generally, the higher the living prices in your location, the greater the price of employing an expert will certainly be.
4. Length of the tunnel: Longer tunnels will be charged at a greater price than their shorter equivalents so whether the tunnel runs from the roof to the 2nd or very first flooring will certainly impact the sun tunnel price.
5. Ease of gain access to: Flexible tubes are fantastic for homes where sun tunnels do not run in a straight line from roofing to ceiling.

Velux windows actually refer to one brand of roof window, which are windows that sit in your roof space and allow light and ventilation into your loft. But how do you install a Velux window? If you’re a competent DIYer, it’s not as difficult as you might think.

You can normally install roof windows entirely from the inside, so you don’t need to get up on your roof or hire costly scaffolding. They come with detailed installation instructions, so as long as you follow them you shouldn’t have much trouble.

Firstly, prepare the opening by removing enough tiles or slates from the roof. There’s no need to go out on the roof – access them by cutting away the felt underneath which will give you access to the tiles and battens. Cut away one of the battens from under a tile, then you can slide all the tiles into the roof space. You’ll need to cut away the roof timbers to make the right size opening, then add more timbers to strengthen the ones that are left.

Next, remove the opening sash from the new roof window then fit the frame into the new opening using the brackets provided with the window. Then fit roof flashing between the new window and the roof so you don’t get any leaks. Then lay your tiles back in position around the new Velux window; you’ll probably have to cut some to shape which you can do with an angle grinder. Always cut them on the ground, not in position on the roof.

Lastly, fit the sash back onto the window and you’re done!

If this sounds like too much hard work, plenty of window installers will be able to help you fit a Velux window and will probably be able to provide a much cleaner finish.
