How Often Do Flat Roofs Need Replacing?

When a flat roof needs to be replaced is determined by a number of factors which includes the roof’s exposure to the weather, the condition and age of the roofing materials as well as the construction of the roof. However, with proper maintenance and regular inspection, they should be used for nothing less than 50 years. There are some commonly used types of flat roofs which includes Felt flat roof as well as a GRP flat roof.

Felt Flat Roof

The lifespan of a felt flat roof also varies depending on the quality and grade of the felt roof incorporated. This can make the roof last within the range of 2 to 20 years. More often than not, felt flat roofs are usually installed in such a way to keep the costs down which implies the grades of felts that are mostly used are the economical ones implying a very short lifespan.

In the event whereby a premium grade of felt is incorporated in constructing a roof by professional contractors, will be guaranteed by the manufacturer to last between 10 to 20 years.

One of the major causes of a short lifespan in felts is leaks which should be regularly inspected and repaired once identified. If not, the roof will gradually deteriorate and become a lot weaker due to the action of the sun. However, when a felt roof starts to leak, it’s usually a sign that’s approaching the end of its lifespan and a replacement should be taken into account.

GRP Flat Roof

The GRP flat roof or fibreglass flat roof usually comes with a manufacturer’s guarantee of 20 years and is expected to have a lifespan of a minimum of an additional 10 years.

Unlike felt roofs, they’re more resistant to leaks. However, they should also be regularly inspected for leaks which are caused mostly as a result of installation error rather than the GRP roofing approaching the end of its useful life. If the GRP roof repair does not totally resolve the leak, you should start considering a replacement.

How To Replace A Broken Roof Tile?

If you have a broken roof tile on your property, the next logical step to take is having it replaced as soon as you can. However, this is not the simplest of tasks so you might need some guidance if you wish to do it yourself. If you lack the confidence needed to pull this off as it involves working at height, then we’d strongly recommend you hire the services of a reliable roofing contractor or company who can guarantee the best results for help. In this guide, we’re going to walk you through the processes involved in the replacement of broken tiles. Let’s have a look!

✓ Match your roof tiles perfectly. The most frequently used roof tiles are concrete and terracotta. They may look all similar but they can actually vary in shapes, length as well as thickness. To replace a broken tile, you must first make sure that it’s the same type of tile so it doesn’t interfere with the flow of your roof which can lead to further damage.

✓ Climb on to the roof. Make use of a strong and stable ladder to do this. If you’re not comfortable with heights, simply call in a professional. Falling of the roof would be more expensive.

✓ Remove the broken tile. Lift up the overlapping tile next to the broken tile in such a way to enable an easy removal of the broken one. If you’re not able to life them, then they probably have nails securing them in place. Remove these nails to proceed.

✓ Replace the broken tile with the new one. To do this, simply lift up the bottom tiles from the above row and then slide the new tile back in place. If the tiles have been nailed, make sure you also drive a nail through the hole in the new tile into the timber roof batten.

The feasibility of this will depend on the roof’s strength, in particular its load bearing capabilities. This is simply because tiles are heavier than the metal sheeting. Normally a tiled roof will need to take a load capacity of 60kg per square metre. You will need a trusted roofing company to advise on this.

How Much Are Roof Tiles?

The way your roof looks speak volumes about your home or property. When you have an attractive roof installed, you give a huge impression of how beautiful the interior of your house is.

Roof tiles are the prefect roofing material if you wish to have your house looking elegant and decent. However, what turns off most homeowners about roof tiles is the belief that the prices are not budget friendly. This is absolutely false and in this article, we’re going to give you a rough estimate of the cost of roof tiles.

The price of roof tiles includes the cost of removing and getting rid of the old roofing materials, the cost of purchasing new roof tiles in the market as well as the cost of installing them on your house. There are a plethora of factors that affects the cost of roof tiles. These factors include the height and size of the roof, the roof’s design, the roof’s pitch, incidental costs of labour, the company hired as well as your location. What’s more? A roof with a complicated design such as hips and valleys will also generally cost more than simpler ones. Also, if you happen to reside in a place like London with higher cost of living and greater demand, the cost is also likely to be higher than other regions. As a result, providing an accurate cost of roof tiles is simply not possible.

Generally, the cost of having an entire roof retiled will cost within the range of £10,000 to about £20,000. For a more accurate estimate, you’ll have to identify reputable roofing professionals within your local area and find the roof tile prices that perfectly suits your budget.

How to repair a hole in a flat roof depends on what material your flat roof is made from. If you have an asphalt, felt or EDPM rubber roof, the repairs are quite simple, whereas it’s a bit more tricky if you have a fibreglass flat roof. How to repair a hole in an asphalt flat roof If you’ve got a small hole in your asphalt flat roof, you might get away with using a paint-on fix from a tin. It’s best to use this as a temporary measure to tide you over until you can get in touch with a professional. If the hole is on the flashing, you can add heat-applied flashing tape to it, or use a patch of torched-on roofing felt. There are liquid systems you can use, but usually they’re only available to the trade. Repairing a hole in a felt flat roof It's a similar process to asphalt roofing if you want to repair a hole in a felt flat roof. Use a paint-on fix for a temporary solution, but the best way to repair a hole is to use a torched-on piece of roofing felt to cover the hole and make it watertight again. How to fix a hole in an EDPM rubber flat roof If the hole in a rubber flat roof is small, you may be able to get away with applying some lap sealant to the hole. Only use a small amount, as if you go for a more permanent repair later down the line all of this will need to be scraped off. You can also use a malleable piece of self-adhesive flashing – clean the area, add EDPM primer and stick the patch on from the centre outwards. Add sealant to the edges if you want to give it more water protection. How to fix pin holes in a fibreglass flat roof If you find pin holes in your fibreglass roof, it usually means there wasn’t enough resin used at installation. To repair the holes, you’ll need to sand down the entire roof back to the clear resin. Then clean the area with acetone and apply GRP roofing resin – the acetone ensures that the resin sticks. You might need two coats of resin to get rid of all the holes.

Tar and gravel flat roofs are popular because the gravel weighs down the surface of the roof so it doesn’t blow away and it also protects it from sun damage. The tar makes the roof watertight, so you won’t get any leaks. However, sometimes problems occur and you’ll get cracks and leaks. So how do you repair a tar and gravel flat roof?

If you notice leaking coming through your flat roof, try to find the source of the leak. Since water can travel easily, it might not be where you think it is. The first place to check is the flashing, then any parts of the roof with gravel missing. Once you’ve found the crack, sweep away any remaining gravel and clean the area.

Apply a primer to the area and allow it to dry. Then, apply a tar and gravel roof patch that you can get from most DIY shops. Patch 2-3 inches around the damaged area, creating layers, and ensuring that there aren’t any air bubbles or gaps. Then you should cover the entire patch with gravel.

Before you try to repair a tar and gravel flat roof yourself, consider how much of the roof needs repairing. Professionals often say that if cracks and faults make up 25% or more of the roof, then you should look to replace it. It might be tempting to try and replace your tar and gravel roof yourself, but it’s best left to the specialists. They will ensure that your new roof is watertight and strong enough to withstand sun damage and storms.

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.

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.
