Some people are very quick learners and can perform many tasks easily. If you are one of the quick learners, this article will guide you on how to do the installation of a flat roof on your own. Whether it is the installation of a new roof, old roof’s replacement, or just the extension of the roof, the techniques and procedures used are very similar.

Structure Of A Flat Roof

It might confuse you but the fact is that the flat roofs are not exactly flat. There is a slight slope which allows the water to flow towards the drainage system. The slope or the gradient is created by laying the joists horizontally across the furrings and the roof opening. The roof boards commonly known as the deck is placed on the top of this structure. Beneath the deck is the insulation material. To keep the insulation together, the deck is nailed to the furrings. The material placed on top of all this material is the one which prevents the rain water from entering inside. This material till a certain time was limited to just mastic asphalt or roofing felt. These are not one of the very good materials and just have a lifespan of ten to fifteen years. Another thing which makes these materials less preferable is the leaks which they are prone to have. To replace this material there is a new material known as EPDM. The EPDM is a single sheet and is produced by custom made rubber. This is a tough material and can last for more than 30 years.

Installing The Flat Roof On Own

Installing the EPDM roof in a rainy weather can be tough. The rain can make the installation tiring and very risky too. Even a very warm weather is not recommended for the installation as the rubber heats up with high temperature and the installation and the handling become very tough.

To begin with the installation measure the sheet and accordingly order your EPDM sheet. Make sure your sheet is large enough and covers the whole roof. The sheet should also extend out of the roof in all directions by several inches. The area where the pitched roof and the flat roof meet, you have to ensure that rubber sheet partially runs underneath and upwards the slates. Do this with caution as this will only prevent any rain water from seeping in. To fix the rubber permanently use a heavy duty glue that matches the industry standards. Do not let the glue spread beyond the edges. if this will happen there are chances of the glue to form some knots or kinks which can hinder the drainage.


If there is any flashing at the point where the two roofs align, keep it flat. The flashing should be laid first in order to let the rubber sheet lay above it to give it a slight slant. With these steps, you can install your flat roof on your own.
