We install Energy-Star rated coating systems, asphalt shingles, concrete or clay tile, copper, slate, stone-coated metal panels, standing-seam metal panels, and exposed fastener metal panels. We have factory-trained technicians for installation and repair of all types of roofing systems. We specialize in built-up tar and gravel, modified bitumen (multi-ply), and single-ply roofing systems. We can add slope to existing flat roofs, and we offer custom-designed energy-efficient insulation systems. We provide a great roofing system warranty that covers labor and materials.
The terms low slope and steep slope describe roof slope. Slope is how much a roof slants, or the incline of a roof. In commercial low slope roofing applications, the roof has a slope of less than 3 inches per foot. Steep slope means that the roof has a slope of more than 3-inches per foot. Sloped roofs need to have some slope for proper water run-off or drainage. When it rains, water has to go somewhere, and all sloped roofs require proper drainage. In commercial low slope roofing, water is directed to drains or downspouts, using small areas called crickets and saddles.
Roof systems can usually be restored, depending on the type of roof system that is currently installed on your building. Once restored, they can be warranted for up to 5 to 10 years. The most common roof systems used in restorations are Built-Up, Single-Ply (EPDM and TPO), Slate and Tile.

Metal roofing is one of the fastest growing segments of the roofing industry. Its' popularity is increasing everywhere, due to its' many positive attributes. While a premium metal roof initially costs more than many other types of roofs, it can be a good investment in the long run.
Not only are metal roofs long-lasting, they can also increase a home's resale value, decrease a home's energy consumption (by up to 40%!), and in some areas, reduce the homeowner insurance premiums immensely.
Non-metal roofs start to deteriorate as soon as they are installed and exposed to the elements. UV rays, high wind, and severe temperature changes can damage most other roofs, sometimes drastically decreasing their service life. The average life span of a non-metal roof varies between 15 and 20 years. Metal roofs can last two or three times that long, depending on style, quality, and workmanship. In many cases, a metal roof can be the last roof you'll ever install on your home or business.
Metal roofing comes in a wide variety of designs, colors, and styles. You can purchase metal roofing in shapes that imitate asphalt shingles, tile, wood shakes, as well as the common vertical seam styles. Metal roofing can come stone-coated and smooth. You can also get metal trim pieces to match the color of your roof, or get contrasting colored trim to offset the roof.

Asphalt shingles are currently the most popular type of residential roof material for a variety of reasons. They are relatively inexpensive, starting at around $0.80 per square foot installed and go up from there. Things that determine cost are geographical location, slope of the roof, height of the building, ease of access to the premises, complexity of the project, the particular type of shingle and numerous other factors.
Asphalt shingles are very simple to install enabling many homeowners to do the work themselves. They come in a variety of colors and styles, are fairly durable (some have been tested and have achieved a class IV hail rating - the highest available!), and can be easily repaired and maintained.
Asphalt shingles come in two basic types: glass fiber (a.k.a. fiber glass) and organic. Organic shingles consist of an organic felt material which is generally paper saturated with asphalt to make it waterproof. A top coating of adhesive asphalt is then applied and the ceramic granules are then embedded. Organic shingles contain around 40% more asphalt per square (100 sq. ft.) than their glass fiber counterpart which makes them weigh more and gives them excellent durability and blow-off resistance.
Glass fiber shingles have a glass fiber reinforcing mat manufactured to the shape of the shingle. This mat is then coated with asphalt which contains mineral fillers. The glass fiber mat is not waterproof by itself. It's purpose is for reinforcement. What makes the glass fiber shingle waterproof is the asphalt. However, the asphalt itself will not stick to the mat. For this reason, fillers are used. The fillers in the asphalt cling to the glass fibers in the mat. The asphalt then encapsulates the glass fibers, fills all of the little holes and voids in the mat rendering it waterproof. After this cools a bit, an adhesive asphalt is used to cover the mat and the ceramic granules are then embedded.
The ceramic granules are there for two reasons. The primary reason is to protect the shingles from the sun. The sun's UV rays are very damaging to asphalt and cause it to deteriorate prematurely. This is one of the same reasons that gravel is used on built-up roofs. The second and more obvious reason for the granules is aesthetics. Asphalt shingles are available in a wide variety of colors to match almost any facade or landscape.
So which type is better? By far, the more popular shingles are the glass fiber ones. This may be attributed to the fact that they are cheaper and easier to manufacturer than organic shingles making them more cost effective to the homeowner, or it may be that they are easier to work with, or they may simply be a personal preference of the roofing contractor.

Slate and Tile
Slate is one of the most aesthetically pleasing and durable of all roofing materials. It is indicative at once of the awesome powers of nature which have formed it and the expertise and skill of the craftsman in hand-shaping and laying it on the roof. Installed properly, slate roofs require relatively little maintenance and will last 60 to 125 years or longer depending on the type of slate employed, roof configuration, and the geographical location of the property. Some slates have been known to last over 200 years. Found on virtually every class of structure, slate roofs are perhaps most often associated with institutional, ecclesiastical, and government buildings, where longevity is an especially important consideration in material choices. In the slate quarrying regions of the country, where supply is abundant, slate was often used on farm and agricultural buildings as well.
Because the pattern, detailing, and craftsmanship of slate roofs are important design elements of historic buildings, they should be repaired rather than replaced whenever possible. The purpose of this Preservation Brief is to assist property owners, architects, preservationists, and building managers in understanding the causes of slate roof failures and undertaking the repair and replacement of slate roofs. Details contributing to the character of historic slate roofs are described and guidance is offered on maintenance and the degree of intervention required at various levels of deterioration.
Clay tiles are one of the most distinctive and decorative historic roofing materials because of their great variety of shapes, colors, profiles, patterns, and textures. Traditionally, clay tiles were formed by hand, and later by machine extrusion of natural clay, textured or glazed with color, and fired in high-temperature kilns. The unique visual qualities of a clay tile roof often make it a prominent feature in defining the overall character of a historic building. The significance and inherently fragile nature of historic tile roofs dictate that special care and precaution be taken to preserve and repair them.
Clay tile has one of the longest life expectancies among historic roofing materials — generally about 100 years, and often several hundred. However, a regularly scheduled maintenance program is necessary to prolong the life of any roofing system. A complete internal and external inspection of the roof structure and the roof covering is recommended to determine condition, potential causes of failure, or source of leaks, and will help in developing a program for the preservation and repair of the tile roof. Before initiating any repair work on historic clay tile roofs, it is important to identify those qualities important in contributing to the historic significance and character of the building.
