Roof Shingles – An Overview Of Popular Roofing Materials

Roof shingles are used to cover roofs and consist of individual members that overlap. Traditionally shingles were referred to wood shingles. Today a range of materials are used to make roofing shingles like asphalt, asbestos, composite and metals. They are usually rectangular in shape and laid in rows starting from the bottom most edge of the roof. As you go up the shingles are laid side by side with a overlap. When it comes to roof installation one basic and first lesson to learn is to employ overlap for everything. This prevents water and moisture from seeping into the home through the gaps in roof. So, when laying out shingles not only should there be overlap on the sides but also when you are placing the next row.

At the ridges, earlier metal caps made of copper or zinc was used. Today, modified shingles with plastic underlay is used. This gives an uniform look and feel to the roof. The metal cap jutting out at top could seriously mar the appearance of the home. But, today’s shingle laying techniques eliminate that need.

Roofing shingles are available in a variety of materials ranging from asphalt, wood, cement, slate to metals. Each type of shingles comes with various ratings for fire, impact and wind. Different standards apply to different regions and states. There might be local variations inside each state too. These standards have been set for maximum safety for homeowners and citizens. So, it is best practice to follow them for the good of your family and the community you live in.

Wood and paper-based asphalt shingles are prone to fire hazards. They are now not preferred because of dangers of an accidental fire destroying home and endangering lives. The manufacturers are coating wood with fire-resistant non-inflammable materials which makes it safer for them to be used.

The natural oils in cellulose structure of the wood keeps it protected. Over time with constant exposure to sun, the protective oils get softened and washed out when it rains. This causes a gradual corrosion in the wood shingles. You will find more erosion along the gutters and other natural valleys in the roof design where there is more water flow. Eventually as the oils are washed out the wood starts to rot, warp and curl. This exposes the nail heads causing them to rust. Water then seeps through the gaps left by the rusted nails and rotting shingles.

The protective nature of the asphalt is because of the long chain hydrocarbons. These also breakdown due to prolonged exposure to sun and rain. The loss of protective oils in asphalt results in its shrinking and other damages described above for wood shingles.
