A slate roof is a natural product, a type of metamorphic rock which is highly durable, making it very suitable for roofing. Slate is very close-grained, and it cleaves readily into thin tiles which can be used for roofing, flooring and other applications. As well as being very water resistant, slate roofs are able to withstand heavy accumulations of snow. Lasting for many years, the roof can increase the resale value of a structure, because slate roof is viewed as a luxurious amenity. Once the roof is installed, it will require less maintenance than other roofing types.
Roof tiles are traditionally made from locally available materials such as terracotta or slate. Modern materials such as concrete, plastic and metal are also used and some clay tiles have a waterproof glaze. As well as being designed to keep out rain, air circulation is often enhanced with the use of roof tiles. Tiles hold up better than most other materials in harsh weather conditions; while keeping heat in during cold months and out during warmer months. Fire resistant and available in a variety of colours and design, roof tiles are versatile and will compliment any house.
Plastic asphalt roofing is a roofing material commonly used for buildings that feature a low sloped roof pitch. Modern elastomeric asphalts are hard wearing and very ply able materials. They are often used for highly trafficked areas, such as walkways, balconies and car park areas. Asphalt roofs are an easy to install, economic alternative with a relatively large life span. Insulation can be used under asphalt to improve UV value of the building.
Lead, Zinc & Copper
Lead, zinc and copper have been used in the construction industry for many years, and as roofing materials with proven track record, these products can be expected to last over 50 years. Lead can be formed into complex shapes by either dressing or welding (referred to as “burning”) and is commonly used for flat roofing, vertical cladding, flashings, soakers, etc. at abutment and termination details in association with all of the other types of roof and wall coverings.
Fixings of lead will normally be carried out with copper nails or stainless steel straps used to secure against wind uplift. These materials are malleable and versatile, long lasting and look good. With a high resistance to corrosion they last a long time.
