    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 felt?

    How To Replace Flat Roof Felt

    Also referred to as tar paper, roofing felt is installed underneath the roof’s shingles to help deny water access to your home. Installing the roofing felt in overlapping layers builds a water barrier in situations whereby the weather damages or blows away the shingles. Although the application of a roofing felt on a flat roof is relatively easier and safer than working on a peaked roof, it’s advisable to take enough care and precautions. If you lack proper training and experience for this task, we’d recommend you employ a reliable professional to guarantee the best results and save you from further headaches especially in cases whereby unfortunate errors are made. This step by step guide will give you a good insight into the flat roof felt replacement process.

    • Take a measurement of the width and length of the roof.

    • Calculate the square footage by multiplying the numbers.

    • Multiply the square footage gotten by three (it’s advisable to install three layers of roofing felt to create a really strong weather barrier).

    • Use a claw hammer to remove the existing roofing felt.

    • Use utility knife to cut the new felt to fit the length of the roof.

    • Place the first piece along the roof’s edge and use a hammer tacker to tack the felt in place with staples or galvanized nails and hammer.

    • Put the staples or nails at every 6 inches along the side touching the roof’s edge as well as down the short sides.

    • Repeat the same process for the second piece, laying it out beside the first row of felt.

    • Cut a piece of felt to the appropriate length using a utility knife to begin the second layer of roofing felt, and cutting it in half, lengthwise.

    • Apply construction adhesive along the first row using a trowel.

    • Press the first piece for the second layer onto the adhesive. Repeat this process until the roof is covered with a second layer

    • Apply construction adhesive over the second layer to install the third layer. Begin with a full piece of felt without cutting it in half.

    • Overlap each piece by 2 inches until you’ve completely installed the third layer.

    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.
