As a property owner you’ll have to look into the pros and cons of replacing your flat roof or opting for simple repair work. Replacing a flat rood can be a big investment, but if left unchecked it can lead to bigger problems further down the line and can even endanger the lives of those either living or working underneath it. Here are some of the considerations you should look at when thinking about carrying out repair work.
Slope and Drainage
Ensure that your “flat roof” isn’t actually 100% flat. According to The Daily Telegraph, a roof needs to have a gradient of at least 1 in 80 so that rainwater can flow into the surrounding drainage system. Water collecting in the middle of a roof can lead to serious leaks, encourage the growth of mould and mildew and cause structural damage later on. While you’re at it, take a look at the drainage system to make sure that the rainwater is flowing away and not backing up causing water to collect.
Make sure that your roof deck is structurally sound and in good condition before you embark on repairing your flat roof. If you see anything that could compromise the roof deck such as corrosion, damage, water ponds or separation, then you should seriously consider replacing your roof deck before you carry out repair work on the flat roof.
Insulation and Waterproofing
When repairing a flat roof, it is essential to install a durable waterproof membrane. This work should be carried out by a professional, such as Plymouth flat roofing experts http://centralroofingsw.co.uk/grp-flat-roofing-plymouth/. You can also look into the heat resistance of your roof, as this will impact the amount of energy you need to heat or cool your home. Darker-coloured roofs absorb far more sunlight than lighter-coloured roofs, resulting in more insulation and less need for central heating. This is something to consider the next time you are looking to repair your flat roof.
If you opt to replace your flat roof, make sure that you choose one that has a good longevity and also comes with a warranty. Look for one that will be low-maintenance and robust, as a roof that needs constant maintenance is a roof that will cost you more in the long run.
