Pitched roofs have been typically seen around the country, but now it seems the flat roof is growing in popularity. There are a few significant reasons for this as well, including the fact they're cheaper to have constructed and are far better for energy efficiency, saving you money on energy costs.

What's more, the flat roofing is good for being resilient to the flippant climate conditions the UK is notorious for. The style of roofing can even be coupled with practically any kind of material too, dependant upon your requirements and existing property.

    FAQs

    What is overlaying?

    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 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.

    how much is a new flat roof?

    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.

    I’ve got ponding on my roof. Do I need to replace it?

    Ponding is where you see pools of water appearing on your flat roof. Unless your roof is leaking or showing other signs of damage, you don’t need to replace it. When you do have your flat roof replaced, tell the contractor so they can find out the cause of the ponding.
