Pitched roofs

Most houses in the UK are built with pitched roofs. Pitched roof are the best option simply because of our weather patterns – rainwater runs off an angled (or pitched) roof more efficiently. The angle of the pitch that is used depends on a number of practical considerations, the choice depends on what sort of useful space you want to have in the roof. If you are designing a house with a cold roof (ie one that is primarily used for storage rather than living space) then you will probably want enough space to accommodate a cold water tank and any storage. You will also want to have sufficient headroom to move about relatively comfortably in the loft – so about six foot in the centre.

The result of these considerations is that the normal pitch of the roof on a domestic property is between 300 and 450.


Lower pitches tend to be used more commonly on extensions. A single storey extension on the side or rear of the house may need to have a lower pitch in order to avoid interference with first-floor windows. In this case we find home owners tend to choose a roof tile that matches the tile on the main roof of the house, but it is important to chose a type of tile that is suitable to use for shallow pitches.

Any given roof tile has a minimum pitch at which it is effective at keeping the rain out. If you try to use them below the minimum pitch they will not keep out the driving rain. Correctly installed plain tiles, for example, will provide a totally waterproof pitch at 350 and upwards.

To get the same degree of weather tightness at a lower pitch we suggest large format tiles or interlocking large format tiles which can accommodate a pitch as low as 220.

In any pitched roof design we check that the tile the customer requests is designed for that specific roof pitch.


Flat roofs

The modifiers provide a tough, rubbery property to the product and add flexibility. Modified bitumen sheets are manufactured in a consistent, controlled environment and are generally coated or covered with mineral granules. Modified bitumen systems are more flexible than BUR systems, yet share many of the advantages, including good resistance to roof traffic. They are a good choice as a replacement for a BUR system or on certain high traffic roofs.

Velux Windows

Velux is one of the leading brands in windows, offering a wide array of roof windows and skylights for sloped and flat roofs and vertical walls. As Velux window suppliers we offer a complete range of options so we’ll have something for every property. We pride ourselves on our extensive knowledge of their products. We aim to offer the best windows and the best service at the best possible price.


Centre pivot and top hung windows are perfect in loft conversions or other spaces where there may not be enough vertical wall space to install traditional windows. Velux sloping and vertical combo windows are similar, but benefit from the addition of a vertical window pane. These are generally larger in surface area and let it more light, but they must be installed where the vertical wall meets the roof.

Velux also manufactures specially designed windows for flat roofs, while the Velux “Cabrio” balcony system is a roof window which opens to become a balcony. The Velux “Conservation” range is designed to integrate with traditional building looks, winning favour on planning applications. The electric and solar powered “Integra” range offers the ease and convenience of remote controlled opening and closing – ideal for anyone with windows that are too high to reach.

Each Velux window style is available in a choice of sizes and different roof pitches. Choose a single installation for smaller roof spaces, and double or triple installation to maximise light in a larger room.

By ordering from us, you can be sure you’re buying some the best windows available. We sell only the highest quality products from leading brands, which enables us to offer a ten year guarantee on all roof windows, panes and flashings.

Lightweight tile systems

The use of lightweight roof tiles rather than traditional clay ones can help save time and money, while also being an environmentally friendly option. Lightweight tiles tend to be quicker to install, and this saves on labour time and costs. Because more of them fit in a single truckload than regular roofing tiles, larger amounts can be transported to a site more quickly, reducing fuel and labour expenses, and cutting down on carbon emissions.


You should find you need fewer of these roofing tiles to cover a roof, and this also saves you money. Modern lightweight tiles are available in sleet, concrete or slate, and are very versatile for use on a wide range of commercial and residential building projects. You can get these tiles, sometimes weighing less than 8lb per square foot, in a range of colours.

They tend to be easier to handle than traditional materials, so they are very safe, particularly when working at height. Long-lasting lightweight roof tiles combine the elegance and distinctive appearance of their heavier counterparts with the convenience you’d expect from a modern product. They are low-maintenance, fully fireproof, and resistant to UV rays, wind, rain and hail.


Cedarwood shingles


Wood shingles give a home that antique look without having to be so old. They are commonly used for roofing shingles as well as siding. Wood shingles or cedar shakes are making a come back in many house designs. They are as easy to install as a traditional shingle and typically last nearly as long. They are very inexpensive compared to asphalt and cover nearly the same area as a bundle of asphalt shingles may cover.
