Choosing A Flat Roof For Your Extension

Although derided by some, flat roofs have their purpose and even their fans.

The advantages of flat roofs include never having to re-tile again and being able to stage roof top protests more easily, should the urge take you.

However, there is more to decide upon than simply having a flat roof.

Roofs can be covered in a variety of ways and depending on where you live and the climate, you may need to think carefully about weatherproofing, especially against the rain.

UPVC FLAT ROOFS

UPVC (or Polyvinyl Chloride) is a chemical plastic.

This makes a great and long lasting roofing material.

However, we would advise that it is best used on out buildings such as garages and garden sheds, as opposed to the larger house extension.

This is because it is better used on roofs which have a smaller area.

A UPVC roof makes a reliable waterproofing structure and when it is coated with plastic resin it is also very fire resistant.

If you’re going to pick this and you even remotely care about the contents of your garage or shed, you don’t want to skimp on the quality.

Cheaper UPVC can go brittle after a while, so we would suggest a product that has extra plasticizers which will boost the elasticity in the roof.

This additional step does cost a little extra – but remembering that the surface area it is being used on is quite small, this shouldn’t be a major consideration. It will really help the roof against heavy rain and from sagging or collapsing under the weight of the puddles.

The main disadvantage of UPVC is that isn’t very environmentally friendly, because of its utilization of petroleum and gas.

For a more sustainable garage roof, you might want to try one of our other options.

 ASPHALT ROOFING

Not everyone realizes that asphalt is a substance which is not only used in paving, but can also be applied to a flat roof.

Asphalt makes a great flat roof covering, for all the same reasons it makes a great pavement surface.

It is tough, long lasting and hard wearing. It can be applied quickly and a professional roofer or asphalt paving contractor can lay, coat and install a small roof in a day or two.

Better still; the asphalt surfacing can then be seal-coated for maximum weatherproofing against all the elements – not just rain water.

And if you ever should get cracking or potholes, it can be quite easily rectified.

Repairs to your asphalt flat roof can be carried out by a qualified driveway paving contractor, as well as a roofer, so this is something to bear in mind and which may give you a wider choice of provider, when you are looking for someone to undertake your job.

Finally, asphalt is one of the least expensive options – another great reason to pick asphalt for your flat roof outbuilding or extension!


FIBERGLASS

Fiberglass is an extremely strong material and great for garages, outbuildings and even commercial properties.

This is a material which is made from a variety of things, but ultimately a type of plastic resin, which is cut with glass fibers to provide the strength you need from a roof.

Will it break? Will it heck! Boats are constructed from fiberglass, which gives you some indication into its durability and its waterproofing.

Fiberglass is the slightly pricier option for the flat roof, but we think it is worth it, as it will last between twenty to thirty years – and perhaps even longer!

Whichever option you pick, don’t let the purists put you off the idea of a flat roof for your extension or outbuilding project. They can last just as long as a pitched roof can do, with the correct maintenance!
