Single-Ply PVC Roofing (Polyvinyl Chloride)

DuroLast Master Contractor

PVC roofing has been a flat or low-slope roof favorite for several decades. It’s long track record proves that it provides a phenomenal watertight system with its heat-welded seams and prefabricated accessories. It’s quick to install, non-disruptive, and very energy-efficient.

A PVC roof system is available in 40 mil, 50 mil, 60 mil as well as 80 mil for special circumstances. With the option of a mechanically fastened system, or fully adhered, it can meet the needs of the individual building.

The Features & Benefits

Water-Resistant | This is a given right? However, the heat-welded seams are extremely strong. With the absence of adhesive, seam failure rarely, if ever occurs. PVC is also known to withstand high and low alkaline conditions and deter mold, bacteria and plant growth.

Durability | PVC membrane is inherently resistant to fire, chemicals, great, high winds and easily accommodates a wide range of climate and temperatures.

No Disruption | For most re-roofs, the installation of a PVC is quiet, quick, safe and installed without loud machinery, hazardous materials, hot tar, fumes or mess.

Highly Reflective | While PVC can come in various colors, white is the most common choice as it delivers the best energy-efficiency. This “Cool Roof” offers cost savings in the reduction of energy consumption that is tangible for building owners and managers.

Eco-Friendly | While the PVC reflects the sun, and mitigates the heat island effects in cities, its also recyclable after its useful life has ended.

Meeting the most stringent building codes, PVC roofing will continue to gain traction with building owners in the roofing industry.

Metal Roofing and Edge Details

The use of various types of metal for roofing is not a new concept as it dates back to the 1850’s. As a trusted, proven method of water shedding, the options for styles, profiles, and colors are greater than ever. While the initial costs of material may be higher than other types of roof systems, metal roofing is well known for its longevity while enhancing the appearance of the building. Choosing between vertical leg structural or trapezoidal structural, and between concealed or exposed fastening systems can be complicated for a building owner. Diversified Services can guide you through the selection process and take the worry out of the decision.

The Features & Benefits

Durability | The life of a metal roof can last more than 40 years. It is inherently strong and can withstand at least 50,000 pounds of pressure per square inch and gusts of over 100 miles per hour.

Curb Appeal | Metal roofs have come a long way in color and design. With 11 different profiles and more than a dozen color choices, there are many ways to create the aesthetic look you might be after.

Maintenance | A properly construction and installed metal roof can create a virtually maintenance free roof system. It can stand up to extreme temperatures, high winds and hail with little required maintenance.

Energy Efficiency | Metal naturally reflects the suns UV and infrared light rays, making it energy efficient. For an even greater impact, we recommend choosing a lighter color.

Roof Coatings

GAF Roofing

Some version of the roof coating has been around for centuries, and with the technological advances they are still a viable option for many roofs today. With various formulations such as silicone, acrylic, and urethane, they can be applied to low slope roofs on residential, commercial, and industrial buildings. Roof coatings are often used as a protective barrier to extend the life of the current roof system and can reduce the temperature of the roof, therefor reducing energy costs.

The Features & Benefits

Easy Installation | The installation process has become much more simplified over the past few decades making it a fast and efficient option.

Cost Savings | Often roof coatings are much less expensive than a full roof replacement.

Energy Savings | Reflective roof coatings can help keep the roof cool which reduces the amount of energy your building uses.

Protection | The waterproofing nature of coatings create an extra barrier of protection, keeping the interior of the building dry.

Diversified Services can help determine which roof coating system would provide the best solution for your roof system.

We are authorized to install GAF, Duro-Last, Mulehide, Andek, and more.

Shingle Roofing

Owens Corning

In the early 1900’s shingle roofing slowly hit the market with asphalt saturated pieces, surfaced with stone. The past 12 decades have lent itself to innovation and improvements that lead us to asphalt shingles that use a fiberglass mat as the core. The shingles are now flexible and shed water efficiently. They are durable, cost-effective, easy to maintain and can last for decades.

The Features & Benefits

Versatility | Shingles are fully capable of covering a wide range of roofs of different sizes, shapes and forms. Shingles can seamlessly cover even the most complicated of designs.

Design Options | With shingles that can now resemble slate, shakes and dimensional shingles, the combinations of color and design is nearly endless.

Moisture Protection | The essential function of a roof system is to keep your building protected – Shingles do this well. Along with a watertight sealant, shingles are manufactured with a fiberglass mat core and saturated with asphalt and granules to ensure a water barrier.

Cost Effective | Asphalt shingles are so common these days, one of the reasons is due to the cost-effectiveness of the materials combined with the length of performance.
