Some roofing contractors tend to work with any material or product you can think of, while others will prefer to only use a select few products that they believe are best. However, there are some roofing products and materials that most roofers will try to avoid as much as possible – either because they require a steep learning curve, because they’re very expensive, or because they don’t provide good enough quality.

Older materials that are no longer used as often typically include certain metals and paints that have been proven to have a hazardous effect or to be unreliable. Lead based paint is no longer used for health reasons, while aluminum roofing sheets are noisy, easy to dent and more expensive than other metal roofing materials. According to Centennial roofers that have been in business a long time, copper is also a roofing material that is no longer used as often as it was in the past due to the growing demand and price of copper.

Although still used quite heavily in some areas, most wood shakes are not as popular these days as composite shingles and metal roofs. Wood is flammable and more easily affected by humidity, bad weather and pests. So you can expect roofers to promote alternative materials that solve these problems more effectively.
