Aspahlt Shingle RoofingThe asphalt composition shingle is by far the most popular and widely used residential roofing material on the market today. It is estimated that about 90% of all homes in the Maryland, DC and Virginia areas have composition shingle roofs installed. Our professional roofers have installed hundreds of quality composition shingle systems in the past three decades.

Composition shingles, sometimes referred to as asphalt shingles or fiberglass shingles, are essentially made using asphalt, paper, crushed rock, and fiberglass which are all compressed into a highly durable shingle strip. These shingles are lightweight, very durable, and can be very cost-effective, depending on which shingle you choose.

Their popularity is also due to the fact that they are available in a wide variety of styles and colors, making them an ideal product for those who would not only like to save money, but who also don’t want to sacrifice aesthetic value. It is also easy to get the materials you want, because they are so widely used – something also to consider if you ever need additional material later on to repair damage. In addition, unlike some tile or slate roofs, asphalt shingles can be walked on without worry.

Cedar shakes and shingles have been used for hundreds of years. They have proven their longevity in actual weather conditions, across all types of climates. Cedar shakes and shingles contain oils that make them naturally rot and insect resistant. They offer a natural look with a lot of character. Because of variations like color, width, thickness, or cut of the wood, no two shake roofs will ever be the same.Cedar Shake Roofing

Roof construction plays a major role in determining the lifespan of cedar roofs. Proper design is absolutely critical to ensure long-term roof integrity. Proper installation will help maximize the life of cedar products. Adequate ventilation safeguards against heat and moisture buildup in the attic area, as well as prevents water from accumulating at the bottom of the roof and then freezing, known as ice damming.

For an even longer life span where climate is a factor, pressure treated (CCA) cedar shakes should be installed. Pressure treated shakes should always be used in high humidity regions. In fact, the Cedar Shake & Shingle Bureau recommends using these products in the Maryland, Virginia and Washington DC area. The life cycle cost of a shake roof may be high, but if installed properly, you will achieve the maximum intended life span and a great natural look.
