London

London is the capital city of England and is still caught in the excitement of the 2012 Olympic Games which graced the city. The multi-million pound venture really helped to provide a range of new jobs across the city and saw a number of housing developments mainly in the Stratford area. London remains to be the most popular visitor city in England with attractions such as Buckingham Palace, Big Ben, Madame Tussauds and also the Thames River. Houses are diverse too, way back to Tudor, Georgian and Victorians eras.

    FAQs

    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.

    how much to replace a flat roof?

    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.

    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 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

    • Tidy up and clear out the debris
