    What Is The Average Cost To Replace A Flat Roof?

    Are you interested in knowing how much it costs to replace a flat roof? Here, you’ll discover a price breakdown for replacing flat roof. This includes a number of price determining factors such as materials costs as well as cost of labour and cost per square metre. All these enables you to make easy calculations so that you can determine a flat roof replacement estimate for your own project.

    The type of flat roof that is the most common type is the garage roof and for the replacement of a single garage roof, the cost will fall between the range of £700 to £1000. Meanwhile for a double garage, you should expect a price increase of about 40 percent to 50 percent. The main price determinant that’s affecting the price of a new flat roof is the material incorporated in making it. For instance, lead or fibreglass are much more expensive when compared to felt roofs.

    Generally, the cost of a flat roof replacement will fall within the range of £700 to £1300 varying largely due to the type of materials to be used by the roofer, the roof’s size as well as whether or not scaffolding would be used. Multiple flat roof applications also comes with different costs which includes:

    • Felt roof ( £40 to £60 per square metre).

    • Fibreglass roof ( £70to £90 per square metre ).

    • Rubber roof ( £80 to £85 per square metre ).

    • Lead bay roof ( £90 to £105 per square metre ).

    • Fibreglass bay roof ( £40 to £60 per square metre ).

    Several professional roofers work in pairs and to hire them you’re likely to be charged between £200 to £300 per day. The project can be completed with just a day’s work, but the installer should be back to make sure there are no leaks.

    How To Replace A Flat Roof

    Is it high time you replaced your flat roof with a new one? If it’s time, then you probably shouldn’t waste another minute! Flat roofs come with multiple upsides and happens to be a lot more affordable than many other options (especially for starters). Not only do they add to your home’s curb appeal and requires a relatively low labour costs as there are minimal risks involved, but they’re also more accessible for maintenance purposes and aren’t as exposed to damage as a pitched roof. However, we’re not here to discuss the various benefits of installing a flat roof, but rather tell you how to install one. If you lack proper training and experience, we’d recommend you hire a trustworthy professional that can guarantee the best results.

    • Wipe the entire roof system clean.

    • Detach and replace rotted roof sheathings.

    • Detach and replace rotted fascia

    • Hire a qualified air conditioning professional to disconnect the existing AC units.

    • Introduce new aluminium air conditioning stands and secure against the deck.

    • Let you qualified air conditioning professional reconnect the existing AC units.

    • Put in place the new air conditioning quick disconnects.

    • Attach EPS fanfold insulation in such a way to cover the surface of the entire roof and secure it firmly in place.

    • Attach the tie-in roof materials where necessary.

    • Attach roofing membrane to cover the entire area of the roofing.

    • Attach membrane to the entire roof’s perimeter.

    • Attach new perimeter flashings (fascia bar, fascia cap and drip edge), secured on the centre at 6. Make use of a good sealant to secure the fascia bar or fascia cap’s top flange.

    • Attach boots on plumbing seal and stacks.

    • Identify the existing vent stacks and seal, and put curbs

    • Put safety walk pad network from the access point of the roof to the air conditioning units.

    • Attach rooftop signs for roof traffic personnel

If your roofing contractor is on the manufacturer’s installer list, it might cover their work. It’s important that you always read through all the information given to you about your warranty so you know exactly what is included.

    how to replace flat roof fascia?

    How To Replace Flat Roof Fascia

    Whatever makes you decide to install your flat roof fascia by yourself and not a professional company, then you must have a clear idea of what to do and do it appropriately. If you lack proper training and experience, we’d recommend you employ a reliable professional to help with the task for the best results and save you some time and money. This step-by-step guide will give a clear insight on how to go about the replacement of your flat roof fascia.

    The tools to be incorporated includes the fascia boards, table saw, plane, crimper, clamps, power nailer, compound saw and chalkline.

    • Prepare and get all the necessary tools to complete the task before commencing as this would save you time from stopping and going back and forth looking for the next tool needed,

    • Install the sheathing and board.

    • Fix white fascias with at least 600mm centres ( a foiled fascia needs just 40mm centre) using a marine grade stainless steel plastic headed nails.

    • Make a space of up to 10mm between the joints for possible building expansion, using super glue to secure the joints to just a side of the fascia.

    • Place this directly on the fascia board’s top (if you’ll be installing ventilation) to create an air pathway.

    • Take note that the type of roof to be installed will determine how you’ll have to install the fascia board. For instance, a hip roof permits you to attach the fascia board onto the roof in a quick fashion, whereas a gabled roof may need you to make markings on the board to achieve the right fit.

    • Consider the depth of the fascia board as it also play a huge role in the installation of the fascia board. For instance, there’ll be additional weights on tiled roofs that will push up against the board. Therefore, if you do not get the appropriate amount of depth, it could eventually collapse.
