Our Roofing Service Process

We’ll start by performing a comprehensive roof inspection to determine the condition of your roof and recommend the most practical and cost-effective option. Depending on your situation, this could entail replacing your existing roof, re-roofing (placing new shingles on top of the existing ones), or performing targeted roof repairs. If your roof is in good shape, we may suggest a periodic maintenance program to keep it that way and maximize its lifespan.

Single Ply Roof Installations and Repairs

Single Ply roofing is a prefabricated sheet of rubber polymers that is laid down as a single layer over a low or steep-sloped roof. The single ply membrane can be loose-laid and weighted down with ballast or pavers, or firmly set on the roof and attached with mechanical fasteners or adhesives.

The Single Ply roofing system is the most reliable roofing membrane, setting the industry standards for roof protection in both reliability and performance. In lab tests and in actual installations, roofing membranes consistently resist tough challenges including intense UV rays, high winds, thermal shocks and chemical residue.

Installing a Single Ply roofing system with high solar reflectivity (SR) and infrared emittance (IE) can be one of the most effective ways to increase a building’s energy efficiency. In addition to Energy Star qualifications, the Cool Roof Rating Council (CRRC) rates Single Ply as one of the highest scores in the industry.

Our vendor partners in the Single Ply industry include major US manufacturers of roofing materials, accessories and underlayments.

Benefits of Single Ply Roofing

Whether a single improvement or as part of a full energy retrofitting project, the Single Ply roof application is an alternative energy source that will save you money through earned tax benefits, incentives and rebates.

Single Ply Roofing offers a number of benefits over traditional BUR (built-up roofs). It has a long life span of up to 40 years or more, provides strength and durability, is eco-friendly, and is available in a variety of materials and colors. Single Ply roofing systems offer the advantages of rapid installation and lightweight construction. These systems provide high puncture and tear resistance, excellent dimensional stability, and high tensile strength. They offer superb resistance to ozone and UV exposure, extreme weather conditions, chemicals, and fire. During installation, no heavy equipment is required and the membrane can be applied during inclement weather. Single Ply roofing is both a flexible and semi-flexible pre-manufactured membrane typically made of rubber or plastic materials. There are three major categories of membranes used in typical Single Ply Roofing applications: thermosets, thermoplastics and modified bitumens.

Thermoset membranes are compounded from rubber polymers, the most common of which is EPDM (ethylene-propylene-diene-monomer). Thermoset membranes have found widespread success as roofing materials because of their excellent resistance to ultraviolet (UV), ozone, and most common chemicals generally found on roofs.

Thermoplastic membranes are based on plastic polymers. Most thermoplastic membranes are manufactured to include a reinforcement layer, usually polyester or fiberglass, which provides increased strength and dimensional stability. The most common thermoplastic membrane is PVC (poly-vinyl-chloride), which combines excellent weathering characteristics, high tensile strength, and long-term flexibility. It also exhibits superb resistance to harsh chemicals and industrial pollutants. PVC roofing systems are able to withstand heat, wind, rain, extreme temperature fluctuations, and many contaminants. The heat-weldable seams provide a strong, watertight seal and result in a clean, fast, and economical installation.

Modified Bitumen membranes are hybrid products that combine the high tech formulation and prefabrication advantages of single-ply with some of the traditional techniques used in built-up roofing. These materials are factory-fabricated layers of asphalt that are “modified” using a rubber or plastic ingredient for increased flexibility. They are then combined with a reinforcing agent for added strength and stability. The two primary modifiers used today are APP (Atactic PolyPropylene) and SBS (Styrene Butadiene Styrene).

White Roof Installations

White historically is the color of goodness and virtue and now is the new green. Today’s society is eager to climb up the green stalks toward global responsibility as scientists have quantified a new benefit: slow global warming.

Every roof has a common enemy: the sun. Where conventional dark-colored roofs absorb the sun’s rays and breakdown due to UV degradation, white roofs can actually reflect up to 88% of the sun’s heat, radiation, and destructive UV rays.

This heat reduction keeps the surface temperature cooler in summer than any regular coated or covered roof. The reduced UV degradation allows the surface to remain highly flexible, so it can tolerate the expansion and contraction (thermal shock) of the membrane without cracking. High durability translates into less maintenance. All of this amounts to years of additional life for the roof.

From the California Energy Commission’s Fifth Annual Climate Change Research Conference:

“White roofs can cut a building’s energy use by 20 percent and save consumers money,” says California Energy Commissioner Art Rosenfeld. “The potential energy savings in the U.S. is in excess of $1 billion annually. Additionally, by conserving electricity we are emitting CO2 from power plants,” Rosenfeld added.

Effective 2005, California’s Title 24 building code requires all flat or low slope commercial buildings greater than 2,000 square feet are required to have white roofs. In addition, most states now offer energy incentive packages for a white roof.

Downspouts, the conduit for carrying water from a gutter, scupper, drop outlet or other drainage unit from roof to ground level is also known as a Leader Pipe.

A gutter (a channel, usually of sheet metal, installed along the down slope perimeter of a roof to convey run-off water from the roof to the drain) requires a professional roofing contractor, who is familiar with compliant standards and differences in roof structure.

Roof Drains

Proper maintenance of the drainage system prolongs the life of your roof. All roofs and drainage systems require regular inspection and periodic maintenance to achieve a long-term service life. Repairs should be performed as soon as they are known and owners should not allow a nuisance leak to persist and develop into a major problem. Poorly maintained drainage systems can degrade insulation or destroy roof systems. While repairs and maintenance work should be performed by qualified roofing contractors, the owner can help maintain the roof and drainage system by seeing that regular “minor clean-up” type maintenance procedures are performed (e.g., regular checking and cleaning of debris from roof and around drains). We will make you aware of general record keeping, inspection, and maintenance procedures.
