Zinc roofing strips are highly malleable and can adopt any shape, including low radius curves and complex shapes unachievable with other materials, allowing for great freedom of design. Zinc roofing is also a natural material and can be recycled indefinitely, making your building environmentally friendly. The only possible downside of applying zinc roofing strips is that they are initially quite expensive.

Installing Zinc Roofing
Although the actual application of zinc roof strips is simple, zinc roofing necessitates that your building meet certain requirements, including geometrical continuity, project structural conformity, and physico-chemical compatibility. For this you will need a thorough roof inspection, which can determine what must be done in order to meet such requirements, and install the zinc roofing accordingly. Not complying with these factors can lead to serious damage, which is why you will need professional zinc roofing installation by a zinc roofing expert. Roof 101 offers all zinc roofing related services at affordable prices, in all major cities.

Modern wood shingles make for historic look

New wood shingles can be designed in different patterns, shapes, sizes and exposure lengths to fit with English, German, Dutch and other styles. With wooden shingles each building looks unique.

History of Wood Shingles
The wood that was used in the past was usually the wood found in the region the home was built. This dependency on local woods contributed to the variety of wood shingles, as did the hand-techniques of using only the inner, heartwood section of the logs for better quality wood, smoothing the wood shingle pine on a shavinghorse to make them fit evenly on the roof. Only later, with steam-powered saw mills, did wood shingles become more uniform. This is the time that Carpenter and Queen Anne architectural styles developed. Even though wood shingles are flammable and other roof shingles are widely available, wooden shingles have remained with us to this day. Today’s undressed wood shingles, their rough surface looking historic, are in fact a modern style.

Wood Shingles and Shakes
Wood shingles that are rough and rustic are called shakes. They come in varying sizes and lengths of 16, 18 and 24 inches. Nailing wood shingles is done in a way that enables air circulation, while shakes are laid so that they form a tight surface. Both methods are devised to assure durability and resist decay. Treatment of wood shingles and shakes can slow down natural weathering processes, though expect a 1/4 inch or more to be lost over the period of a century. Wood shingles and shakes alike can be installed over previous layers of asphalt shingles or wood shingles. Furthermore, wood shingle roof repair is made simpler this way.
