Do you need a Price?

With any roofing structure, one of the main objectives will always be for it to be designed and built to prevent water and dirt from pooling on the glass. This rule applies to any rooflights you may want to install as well.

Selecting the correct angle for your installation will make all the difference in the long run, especially when it comes to extending the working life of the structure.

Let Gravity Work For You

Everything boils down to simple physics, as it is only natural that water and dirt need to be able to easily roll off of the fitting to prevent further damage. In the event that you devote considerable time and resources to installing a skylight, while at the same time forgetting to place it at the correct angle, you could see your investment wasted.

When discussing the benefits of flat rooflight installations, it would be very easy to assume that this would need to be installed with a completely zero degree angle. However, in this instance, ‘flat’ should not be entirely ‘flat,’ as this would lead to excess dirt and water having nowhere to go and run off.

If you picture spilling a glass of water onto a regular table, you will notice that it just stays there until it is mopped up – this is far more complicated to perform on a flat rooflight! Instead, a minimum of a three degree pitch should be used (the maximum being 30o).

An angle of three degrees doesn’t necessarily mean that the fixture will not take on a flat appearance – it will in fact hardly be noticeable unless you are looking at it up close. As a contractor, you can counteract any objections to this angle by stating that it is in the best interests of all concerned.

Avoiding Excess Build Ups

There are two main reasons for not wanting excess water and dirt to remain on a skylight for any extended period of time.

First of all, water pooling and evaporating on the flat surface will leave watermarks on your glass, not a good look.

More importantly, the dirty and stagnant water could result in the growth of algae and other unwanted substances on the surface of your skylight – at the very least this will be an unsightly and therefore unwelcome addition to your property, severely restricting the light passed through to your interior. With an angle of three degrees, the water and dirt will simply wash away.

Protect Your Home

If you believe that mould and other growths are enough of a problem on the outside, you may also be interested to know that seeping moisture from a damaged roof could end up damaging the internal walls and ceilings below.

Interior mould and moisture is far more than just an aesthetic issue, and it can actually pose a serious health hazard. Over a long time, constantly breathing in these poisonous ingredients has the potential to lead to severe respiratory illnesses, and it is therefore sensible to protect any building with a three degree roof slope.

To achieve the desired angled you may be able to place the upstand directly onto the roof firrings. Firrings give a flat roof its fall, this will translate the roof pitch onto the roof light. Alternatively if your fixing onto level roof joist, firrings will need to be placed under the upstand or the pitch can be built into your upstand if yourself or your builder is building it.

The roof light that I ordered arrived on time and appears to be very well made. The instructions were clear and my builder had no problems installing it, other than in getting it onto the roof as it is very heavy. The roof light looks good and I am glad that I was able to buy one with such a good U value as I wanted the light without the loss of heat.

EoS and their staff were very helpful in design and specification for a large skylight. They gave top quality support in the runnup to installation and were very accommodating in helping to source correct vehicle to crane in said (very heavy) skylight.

I'm delighted with my EOS roof lights. I had to choose roof lights that were slightly smaller than I wanted, due to design constraints, but the amount of light provided is wonderful and unexpected. The whole kitchen is lit up, even when the curtains are closed across our french doors. Many thanks EOS, A happy customers.

Really nice company - fast, efficient and pleasant in all my dealings with them. There was a delivery error and they worked hard to find a solution as quickly as possible and did everything they said they would. Really impressed all round - when you are having an extension on your house, you end up dealing with lots of suppliers. I wish they were all as good as EOS.
