Built Up Roofing
Built-Up Roofing (BUR) is one of the oldest and most reliable commercial roofing systems for buildings with low-slope or “flat” roof structures. Started in the 1840's, these roof systems are often referred to as "tar and gravel" roofs. BUR consists of multiple plies of roof felts laminated together with bitumen. BUR consists of bitumen-saturated organic-fiber, fiberglass, or polyester felt. A top-surfacing or a glaze coat of asphalt, aggregate (gravel or slag), fibered, or non-fibered coatings engineered for roof coating, or a granule-surfaced cap sheet.
Single Ply Roofing
Single-ply roofing systems (SPS) have grown in popularity over the past 30 years as a preferred commercial roofing system, due to their ability to provide strength, flexibility, and long-lasting durability, it’s no wonder that architects, roofing contractors and building owners love this product.
Modified Bitumen (MB) roofing is an asphalt-based, close cousin of the Built-up-Roof (BUR) designed for buildings with low-slope or “flat” roof structures. Engineered modified bitumen roofing membranes originated in Europe in the mid 1960's and have been used successfully in the United States and Canada since approximately 1975.
The premier roof for a commercial building, metal roofs furnish building designers and owners with a world of choices; from system design to type of metal to a rainbow of color options. Metal roofing boasts excellent strength, durability, and fire resistance. Metal roofing has an excellent track record that is literally centuries old, and is in service on approximately 50% of all low-rise commercial, industrial and institutional buildings erected over the past several years.
Commercial Roofing Insulation
Gone are the days when roof insulation was simply used as to provide a suitable substrate for the roof covering. The requirement for a suitable substrate remains, but today’s building owners (as well as building designers and building codes) want high-performance insulation under their roof membrane to curb the growing cost of heating and cooling their space. Guardian Exteriors furnishes roof insulation to meet even the most demanding specification.

By far and away the number one covering over the steep-sloped roofs of the United States and Canada are asphalt shingles. Developed over a century ago, asphalt shingles have proven to be one of the most cost-effective solutions for commercial applications.
Natural quarried slate has proven itself for centuries as a serviceable, waterproof roof covering. Depending on the quality of the stone (for the are differences contact your Beacon slate expert to find out more), slate roofs may last from dozens to hundreds of years. Their longevity, however, is not their only quality. Slate roofing is made of natural stone quarried from the Northeast United States, Canada, Virginia, Wales, Spain, China, South Africa, and other parts of the world. They are simple and beautiful roofing systems available in a variety of colors and textures, allowing designers to customize virtually every installation. When slate roof tiles need to be replaced, they can be discarded as clean land fill or in some cases recycled and used for roofing again. Slate roofs, while one of the most expensive roofing systems “up front”, are arguably one of the least expensive money can buy when the entire life of the roof system is taken into account.
