What Type of Roof Tile Should I Choose?
There are many different types of roof tiles, and the original types of roof tile to be introduced hundreds of years ago still remain very popular today. Choosing the right type of roof tile is a crucial step in roof design. Some types of roofing may be better suited for your house than others. Factors such as the slope of the roof and strength of the framing could limit your choices, and the type of roof tile chosen will strongly influence the aesthetic look you achieve (and of course the final cost too!). Your choice of material will come down to personal preference in shape, colour and finish. Both terracotta and concrete tiles are built to last, with a 50-year guarantee on terracotta tiles and a 20-year guarantee on concrete tiles. Some customers prefer the natural beauty of terracotta while others appreciate the versatility of concrete.
Plain Roof Tiles
Plain tiles are small and rectangular in format and have always been the same size (265mm x 165mm) so that a roof will require 60 tiles per square metre as standard. Plain roof tiles perform by overlapping one another densely up to three tiles deep to achieve a watertight layer. It is this functional requirement that creates their distinctive appearance, adding a sense of detail and texture to the roof. This character is enhanced by the effect of cambers longitudinally and across the width. Clay plain tiles can be machine made or handmade, the latter creating the classic rustic appearance.
Pantiles are becoming more popular than ever before and are renowned for their distinctive ‘S’ profile that creates a series of ridges and furrows which result in some the most elegant roofscapes available. The Pantile shape is predominant in the East side of England and Scotland, and areas of the South West. This geographical architectural footprint is a legacy of several centuries of trading during which pantiles were brought back from Holland and Belgium as ballast in trading ships.
Concrete Roof Tiles
Whilst clay roof tiles have been used on roofs for centuries, concrete tiles have become more widespread over the last half a century. Modern concrete roof tiles are made from cement, graded sands and pigments and formed into a number of distinctive tile designs, which makes the, a very lightweight and attractive roofing option. A concrete tile roof can be a very good roof, but only if it and the underlayment, battens, and flashings are installed correctly. Once concrete roof tiles are properly installed, they require little maintenance for the life of the roof. Should a section of the roof ever be damaged or require modification (eg. installing a skylight), only the affected tiles usually require replacement or removal. Approximately 10 concrete tiles are needed per square metre. Less expensive than clay tiles, concrete roof tiles are also heavy but can last a long time and are very fire resistant.
Terracotta Roof Tiles
Terracotta tiles are slightly smaller than concrete tiles. Unlike roof tiles made from other materials, terracotta roofing substantially retains its appearance with age, maintaining the aesthetic appearance of your home over time. Terracotta tiles are crafted from select natural clays that are kiln-fired to temperatures of 1100°C for exceptional character and strength with high colour retention and low maintenance.Depending on the complexity of the roof design, an average of 13 tiles are needed per square metre. They are designed to interlock at both the head and the sides and are laid in either a cross-bond or straight-bond pattern, depending on the profile.
Slate Roof Tiles
Slate roof tiles can improve the appearance of your property and also increase its value. Slate tiles are made of 100% natural stone and they are extremely durable. If a slate roof is installed and maintained properly, it can last up to 100 years. They are also environmentally friendly as they can be recycled, if they outlast the building that they are installed on. In addition, slate is a great natural material that is dense and also water-resistant. Slate can withstand temperature changes, making it a wonderful (and popular!) roofing tile choice, especially for roofs in Cornwall. Another advantage is that slate is also resistant to insects and corrosion and that it requires very little maintenance.
