Flat System

The are many flat roof systems on the market, however we would like to highlight two of the most common used flat roof systems for our company.

Asphalt Built Up Roofs and Water proofing system.

Built-Up Roofing Systems are one of the oldest and most dependable roofing systems on the market today.

The built-up roof system consists of multiple layers of bitumen which are the waterproofing medium; and fiberglass roofing felts which are the reinforcements; combining to form a uniform solid surface. Each type of base, cap, and ply felt is designed to perform a specific function in the roofing system.

These various forms permit the installation of Built-Up Roofing Systems over many different substrates. The bitumen is also available in various grades to accommodate other variations that may be encountered i.e., slope, products, deck, and weather conditions.

The many benefits of installing a built-up roof are: multiple applications, ease of maintenance, multiple layers of waterproofing embedded in hot asphalt, can be used on several different deck types, and makes roof top equipment installation easy.

Water proofing system transforms a roof with seams, gaps, and overlaps into a seamless foundation ready for coating, that makes the process of sealing seams, fasteners and roof details faster and easier. No need to kneel down!. These system are an effective waterproof alternative to conventional tape when preparing a roof for repairs and coating.

Shingle System

Asphalt shingles are a roofing staple all over North America by dint of their low upfront cost and easy installation. They are currently the biggest player in the roofing market, outpacing

all other roofing materials by a considerable margin. Asphalt shingles are manufactured in two different types: three-tab and dimensional. Three-tab shingles are distinguished by cutouts—tabs—made along their long lower edge.

The result, says Joan Crowe, a technical services director for the National Roofing Contractor’s Association (NRCA), is that “each shingle looks like three separate pieces when installed, but it’s only one.” Three-tab shingles have been around a long time and are still the most economical and most popular shingle today.

Dimensional asphalt shingles contain no cutouts, but their lower portions are laminated with an additional asphalt layer.

This creates the contoured, dimensional look that gives them their name. Asphalt sealant bonds the layers, reinforcing the shingles’ waterproof capability. Though durable, dimensional shingles are not recommended for low-sloping roofs, which are more vulnerable to wind-driven rain.

Tile System

There are two different types of roofing tiles, Clay roofing tiles and Concrete roofing tiles.

Clay roofing tiles has the most extensive choice of profiles and styles in the nation, ranging from traditional mission style barrel tiles to flat tiles that deliver the aesthetics of natural slate and wood shake. Clay tile is known for its long-term durability and longevity by being wind, hail and fire resistant. It has proven aesthetic appeal over thousands of years.

Concrete roof tiles. With so many styles and colors to choose from, you’ll find that adding a tile roof to your home is one of the easiest and most effective ways to complement your lifestyle and increase the value of your home. Concrete tile offers an extensive range of styles and colors to compliment any architectural design.

From traditional Spanish barrel tile profiles, to low-profile shake and slate products, concrete tiles offer Class A fire-rating, hail resistance, heat and noise insulation, and can withstand winds of up-to 150 mph.

Metal System

Metal roofing can consist of a high percentage of recycled material and is 100% recyclable.It does not get as hot as asphalt, a common roofing material, and it reflects heat away from the building underneath in summertime.

On a larger scale, its use reduces the heat island effect of cities when compared to asphalt. Coupled with its better insulating abilities, metal roofs can offer not only a 40% reduction in energy costs in the summer, but also up to a 15% reduction in the energy costs in the winter according to a 2008 Study by Oak Ridge National Laboratory.

This finding is based on the use of a strapping system of four inches between the plywood and "cool-color" metal on top, which provides an air gap between the plywood roof and the metal. Cool-color metals are light, reflective colors, like white.

Leak Repair

All roof leaks are caused by a flaw in the progression of water flow. Roofing systems are designed so that the water starts at the highest possible point and flows downward to the next highest point, and so on until the water reaches the edge of the roof.

Sometimes it can be difficult to locate the exact spot of a leak because the water spot on the ceiling inside your house may not be in the same location as the actual leak in the roof.

Water can run down rafters or trusses and show up inside the house a good distance away from the actual source of the problem.

The best way to find the true source of the leak is to climb up into the attic and look for water damage on the underside of the roof deck.

This should give you the best idea as to the location where repair work will be necessary.
