Baltimore homeowners can count on their new roof to provide several decades of protection from the weather. The particular material that is installed has a dramatic effect on the longevity and price of a new roof. Asphalt shingles are one of the most common Baltimore residential roofing materials and come in a range of qualities, colors and styles. Asphalt shingles are ideal because the material is affordable and is usually backed with a minimum 20-year warranty. Metal panels are another great choice for a new roof and can last for 50 years with proper maintenance.
Asphalt Shingles--20 to 40 Years
Asphalt shingles have been the leading Baltimore residential roofing material for years and are ideal for their low price and long life. The product is usually made from an organic or fiberglass base that is waterproofed with petroleum tar. The thickness of the base is one of the main differences between individual products. Thicker shingles are designed for a longer life, but they are also more expensive. On the top of shingles, UV-resistant granules provide color and protection. The granules protect the underlying material from the sun and ensure a long-lasting roof. Most asphalt shingles are rated according to their lifespan, and 20 year warranties are the bare minimum. Thicker shingles usually have a longer warranty, and the highest quality products are usually good for 40 years. Between the 20 and 40-year shingles, there are a range of other choices. Thus, Baltimore homeowners can expect a new asphalt shingle roof to last for anywhere from 20 to 40 years.
Metal Roofing--20 to 50 Years
Metal roofing is quickly gaining popularity in the Baltimore roofing industry. The product is ideal because it is designed to provide years of reliable service with minimal maintenance. Most metal roofing manufacturers back their products with a warranty that is good on the finished surface. Because the finished paint is specially applied, it is usually guaranteed for at least 20 years. Homeowners can also repaint their metal roofing, and the product can easily last for 50 years or more.
Cedar Shakes--15 to 50 Years
Cedar was one of the most common roofing materials during the early part of the 1900s but has largely been replaced by asphalt shingles. Cedar is often chosen for its aesthetic appearance because it brings a rustic look to the home. The quality of cedar varies, and homeowners have several choices. Most products last for at least 15 years. There are also better quality cedar shakes that can easily last for 50 years with proper maintenance.
Clay or Cement Tiles--Up to 100 Years
Clay tiles are not as common in Baltimore as in other cities, but the material is one of the most durable residential roofing products on the market. Clay tiles have been used since ancient Greece and Rome and are usually made from cement, stone or clay. The tiles require little in the way of routine care and can easily last up to 100 years. Clay is one of the most expensive materials on the market, but the price is incredibly affordable when its long lifespan is considered.
Baltimore homeowners have several choices for their new roof, and the particular choice will affect the cost and longevity of a project. Asphalt shingles are among the most popular choices and easily last for 20 years. Some products feature a thicker mat, and the longest-lasting shingles are good for 40 years. Metal roofing is another ideal choice that lasts for 20 to 50 years. A range of different quality levels is available for metal roofing, and some products are custom made for a durable lifespan. Clay tiles are one of the most durable options and can easily last for 100 years.
