How Much Is A New Flat Roof

What is a home without a roof to keep out the elements? Being the first line of defence against intense sun, rain, wind and more, implies they require enough care and attention to keep them in a top condition. Therefore, whether you need a new flat roof or just to replace some tiles, you’d be interested in knowing how much it would cost you to get a new roof before you start making the necessary plans. Here, we’ll give you an idea on the cost of a new flat roof and how you can estimate yours based on your unique requirements.

The size of your roof as well as the material to be used are the two main determinants of any flat roof project’s cost. For instance, a four bedroom detached home’s slate roof will be more expensive than a felted flat roof for a small or standard garage. Generally, in the UK, the average cost for replacing a flat roof will range between £5000 to £6000. However, if you’re on a tight budget and looking for the cheapest possible option, you’ll get a felt flat roof only on a garage at about £1000 to £1500. Meanwhile if you want to replace the entire slate tiles of a large family home, the cost can jump up to a range of £11000 to £13000.

Other factors that plays a key role in the determination of a new flat roof’s cost includes the location, labour as well as materials. For instance, a new flat roof price is likely to be higher in London and the south east than the other regions of the country. Also, labour may cost you around £150 to £250 per worker on a daily basis.

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 Much Is It To Replace A Garage Roof?

The size of your garage will be the main determinant of the cost of a new garage roof. However, the present condition of your roof structure as well as the type of roof covering preferred are also huge factors. In the UK, the cost of a garage roof replacement will be within the range of £700 to £3600.

The first step a pro will take is to remove the existing roofing while also making sure that the timber structure is in a good condition. In the event whereby the timber is rotten, it will need to be replaced before the installation of a new roof. If the garage roof sheets needs a replacement, you’ll have to spend about £30 to £50 per each garage roof sheets. Individual plywood sheet has around 2.4m x 1.2m in measurement and whose price should also be included in the final cost.

The above information applies only to standard roofing for garage roofs with flat roofs being made of bitumen felt and asphalt. In recent times, this is no longer the case with several more options available. Today, EPDM and GRP fibreglass have rapidly become very popular amongst several homeowners in the country. It’s also important to note that modern roofing has greatly advanced over the years even though both EPDM garage roofs and GRP fibreglass garage roofs are way better and of more quality when compared to felt and asphalt roofs. And thanks to modern technology, modern garage roofing possesses a longer life expectancy and as result, are a lot costlier than the conventional ones.

For a medium size single garage (2.7m x 5.5m), the cost for a felt roof per square metre is between £40 to £70, while that of a fiberglass roof and an EPDM rubber roof is between £90 to £110 and £70 to £100 respectively.
