Lewisham

The London Borough of Lewisham is a London borough in south-east London, England and forms part of Inner London. The borough wasestablished in 1965, by the London Government Act 1963, as an amalgamation of the former location of the Metropolitan Borough of Lewisham plus the Metropolitan Borough of Deptford, which had been established in 1900 as divisions of the County of London. Nonetheless, minor boundary adjustments have occurred since its creation. One of the most significant amendments were made in 1996, when the previous part of the Royal Docks in Deptford was transferred from the London Borough of Greenwich.

The principal settlement of the borough is Lewisham. The borough covers a total area of approximately 13.57 square miles. It's enclosed by the Royal Borough of Greenwich towards the east, the London Borough of Bromley towards the south and also the London Borough of Southwark towards the west. The River Thames forms a short section of northern boundary together with the Isle of Dogs within the London Borough of Tower Hamlets. Deptford Creek, Pool River, River Quaggy and River Ravensbourne pass by means of the borough.

In accordance with population estimates produced in the middle of 2014, Lewisham is a borough with roughly 291933 permanent residents. Around 43 per cent of households are owner-occupiers. The Prime Meridian passes through Lewisham. Blackheath, Goldsmiths, University of London and Millwall F.C. are located inside the borough.

    FAQs

    how often do flat roofs need replacing?

    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 can I maintain my flat roof?

    You should inspect your roof twice a year, ideally after rain or snow, to see if it’s draining properly. Also in the Spring to check for damage that may of been caused over the winter months that will need to be put right before the next winter. Have an inspection carried out if you are unsure.

    What guarantee or warranty can I get?

    Most material warranties come from the waterproofing layer manufacturers, and can last between 5 and 20 years. 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 long should a flat roof last?

    It depends on the material you use, but if your flat roof is installed correctly it should last for at least 10 years, and at least 20 if a material other than felt is used. Always question a roofing company when they quote to find out what materials they use and what guarantee's they offer.
