Since Alpha Roofing was established the two companies work very closely together and utilise their geographical locations to make the best use of solely employed labour. We provide a comprehensive range of roofing services for a variety of roof types. We offer full insurance backed warranties for 10, 15, 20 and 25 years on work carried out.
This was a new build project. The client required a large format black glazed clay pan tile to be installed across 75% of the roof area, butting into a large glass roof to the final 25% area. Incorporated into the system was insulation, ventilation and a manual opening Velux roof window. This was a refurbishment project which involved removing all old defective clay plain tiles and associated ridge tiles, and replacing with new Marley Eternit Acme Double Camber Smooth Red Clay Plain Tiles, with matching clay Ridge Tiles, some of which were crested.
The deteriorated coverings to this sports dome we in need of refurbishment. It has an 18mm plywood decking, and is now covered in a Sarnafil light grey PVC single ply roofing membrane, bonded in a solvent adhesive, with all laps hot air welded. A new build project consisting of a high performance felt vapour control layer, 120mm PUR Insulation Board, and new Sarnafil lead grey PVC single ply roofing membrane, fully adhered with a solvent adhesive, with all laps hot air welded. For maximum visual impact, an aesthetic detailing of Sarnafil Dcor Profiles were installed to give the effect of a standing seam roof.
Green Roofs provide a way to reduce the carbon footprint of any building. They are Intentionally Vegetated Roof Surfaces. The roof will need to be waterproofed first, typically with a single ply or built-up felt waterproofing system, prior to the green roof being installed. Green roofs are known to significantly reduce the surface run off volumes and rates of rainfall leaving roofs. The thermal performance of green roofs cannot be given a U-Value currently, but they have been shown to significantly reduce the necessity for air conditioning in summer and can provide a degree of insulation in winter.
Choosing the right tile or slate for your roof can be a daunting consideration, due to the exceptional variety of choice. Tiles can come in a variety of forms, generally made from either concrete or clay. A variety of colours are available to give even the most standard of roofs a satisfying aesthetic finish. Clay tiles have a longer life span than concrete tiles, but concrete tiles offer a cost effective solution to re-roofing. Large format roof tiles, for example Double Roman concrete tiles, tend to be laid with a single lap to the adjoining tiles, nailed to the timber battens beneath.
There are a number of suppliers that we use for all metal and polycarbonate sheeting and cladding works. Sheeting and cladding can be appropriate for a new-build, or a refurbishment project. There are a few different metal sheeting and cladding systems available. Polycarbonate sheeting also has an assortment of systems available. We use the manufacturer Twinfix for our polycarbonate sheets and accessories. Twinfix can offer a range of glazing bar systems. A Twinfix glazing bar or panel system can be suitable for most pitched roof glazing applications.
