Energy Efficiency

energy-star

A high-performance roof can be a powerful asset in reducing energy consumption by becoming an energy efficient roof – a Cool Roof. When used with appropriate insulation on low-sloped or flat roofs, a high-emissivity Duro-Last Cool Zone® reflective roofing system can:

  • Reduce building energy consumption by up to 40 percent
  • Improve insulation performance to reduce winter heat loss and summer heat gain
  • Preserve the efficiency of rooftop air conditioning
  • Potentially reduce HVAC capacity requirements
  • Decrease the effects of Urban Heat Islands and related urban air pollution

Make your roof an Energy Efficient Roof: The Duro-Last Cool Zone reflective roofing system exceeds “cool roof” standards established by these organizations:

  • The EPA’s ENERGY STAR® Roof Products Program has established a minimum standard that requires low-slope reflective roof products to have an initial reflectance of at least 65 percent, and a reflectance of at least 50 percent after three years of weathering. If there is any doubt about whether a roofing system is “cool roof” or energy efficient roof, check to see if it is listed in the ENERGY STAR Roof Products listings at www.energystar.gov. Use their online calculator to determine potential energy savings for your building.
  • The Cool Roof Rating Council (CRRC) is a non-profit association that implements and promotes fair, accurate performance ratings for solar reflectance and emittance from roof surfaces. All tests for measuring relective roofing properties are performed by accredited, independent laboratories following established ASTM International protocols. Performance data for products from numerous manufacturers can be found on the CRRC’s web site at www.coolroofs.org.
  • Title 24 of California’s Energy Efficiency Standards for Residential and Nonresidential Buildings is a wide-ranging “green” construction bill that became effective in October, 2005. Title 24 specifies that new and replacement commercial roofs – virtually any low-slope roofing project that requires a construction permit – must have a minimum initial thermal emittance of 75 percent, and a minimum initial solar reflectance of 70 percent, as rated by the Cool Roof Rating Council. http://www.energy.ca.gov/title24/

Other Energy Considerations:

  • The American Society of Heating, Refrigeration and Air-Conditioning Engineers (ASHRAE) established Standard 90.1 as a minimum requirement for energy-efficient building design. President Bush signed legislation offering tax deductions to buildings that exceed the 90.1 Standard.
  • Lawrence Berkeley National Laboratory recently determined that increasing the R-value of a roofing system in Los Angeles from R-9 to R-15 would reduce annual energy costs by $2,500 and lower carbon dioxide emissions by thousands of pounds.
  • Executive Order 13123, now known as Federal Acquisition Regulation Case 1999-011, mandates that federal office buildings must reduce energy usage 30% by 2005, and 35% by 2010. It also mandates that federal industrial buildings and laboratories must reduce energy consumption 20% by 2005, and 25% by 2010. Federal agencies also must use ENERGY STAR products when available, and decisions must be based on energy and life-cycle cost analyses.
  • In cooperation with state and local governments, many utility companies offer rebates for using reflective roofing systems. These rebate programs are offered nationwide, not just in southern climates. For instance, Excel Power, the fourth largest utility company in the United States, has awarded rebates as far north as Minnesota.
  • Energy efficiency also reduces pollution by mitigating the urban heat island effect.

Advantages

Duro-Last has been the industry leader in producing custom-fabricated single-ply roofing systems, designing each roof to fit building specifications exactly, and manufacturing it under controlled factory conditions.
For building owners and managers, Duro-Last’s custom fabrication of single-ply roofing systems offers several advantages:

  • Studies of roof failures show that most problems occur because of installation errors, particularly at changes in plane on the roof, such as projections, curbs, drains, perimeters and abutting walls. Duro-Last prefabrication eliminates up to 85% of on-site, rooftop membrane seaming, greatly reducing the likelihood of installation errors and leak problems in the future.
  • Prefabricated roofing systems are easier to install throughout the year, even during adverse weather conditions. Installation time is reduced so the contractor can get on and off the job quickly. The relatively small amount of roof membrane seaming done in the field is completed with hot-air welding methods, which are virtually unaffected by cold or damp weather conditions.
  • Single-ply roofing prefabrication dramatically reduces waste, both during the manufacturing process and installation. The roofing contractor orders the exact amount of roof membrane necessary for roof coverage, rather than a collection of raw materials.
  • Prefabrication also appeals to engineers and architects who would like to address a particular structural or aesthetic design problem. Panel sizes, shapes and colors can be pre-planned and prefabricated to achieve desired visual results.
  • Finally, prefabrication allows the roofing contractor to take control of a construction operation in a highly unstable environment. Roofing contractors must plan their roofing projects carefully, and are rewarded with greater worker productivity, a higher-quality installation and more satisfied customers.

In addition to being custom prefabricated, the Duro-Last single-ply roofing system is durable, energy-efficient, installed with no disruptions, code compliant and backed by the industry’s best warranties. The Duro-Last roofing system is the best long-term investment you can make in your building.

Energy costs continue to escalate with no end in sight, and this trend is largely responsible for driving a significant market shift toward energy-efficient commercial roofing systems.

  • 15 + 5 Warranty
  • 15 Year NDL Warranty
  • Cool roofs are effective in virtually all climates. Building owners in some areas have seen a 40% reduction in energy consumption during peak times of the year after installing reflective commercial roofing systems.
  • In non-conditioned space, reflective commercial roofing can reduce workspace heat, improving working conditions and increasing employee productivity.
  • The Cool Zone membrane reflects damaging ultraviolet and infrared rays of the sun that are absorbed by other systems. Penetrating UV and IR rays can degrade the effectiveness of insulation and other building components – often leading to higher operating and maintenance costs.
  • When placed on rooftops with reflective membranes, HVAC units have a smaller “degree difference” of the air they need to cool because the ambient temperature is lower than on dark-colored roof surfaces. This decreases the cooling load as well as unit wear and corresponding maintenance costs. A Cool Zone roof may also enable the use of smaller, lower-cost HVAC units.

Life Cycle

As a building owner and/or building maintenance manager, you know that operational costs have continued to escalate. With dramatic budget cuts and buildings that are in need of repair or updating, you have to utilize every source you can to get the best value for your investment.
Saving money on energy costs and products has become an increasingly important task in the facilities world. Sustainability must receive a lot of attention. Roof sustainability means the design, manufacture, maintenance, life-cycle impact, adaptive re-use, destruction and recycling of the roofing components that help meet the long term environmental standards demanded by today’s high-performance buildings.

What are the qualifications for a sustainable roof?

It is important to select a roof that delivers the Five E’s of high performance roofing:

  • Energy: Reduces energy use and improves a building’s efficiency in any climate.
  • Environment: Minimizes impact on the earth’s environment throughout the roof’s life and helps maintain healthy, productive environment inside the building.
  • Endurance: Meets or exceeds performance requirements for long life: all-weather reliability; chemical, fire and puncture resistance; and ease of maintenance and repair.
  • Economics: Makes economic sense at the time of purchase and in the long run. A true economic comparison analyzes the cost of a roof throughout its life-cycle.
  • Engineering: The right materials, design and manufacturing process enable the other four E’s, resulting in a complete, integrated roofing system that can be installed quickly and easily and performs reliably over the long run.

What to do with that old metal roof?

Metal roofing dates back to about 1000 B.C. when a temple in Jerusalem was built with a copper roof. Later on in human history, metal roofs caught on in certain parts of the world, like the Virgin Islands, and were effective for several reasons. They were strong enough to resist earthquakes, dramatic heat, and tropical hurricane winds. They also had an appealing look to them, which as we know, is very important in the design of structures.

Most people don’t know that there are really two types of standing seam metal roofs: architectural and structural. Architectural are those you can see from the ground. They are aesthetic in design and intended to look good on the building.

Structural standing seam roofs are flat/low-sloped roof decks that are intended to be more functional than aesthetic.

Modern metal roofs are among some of the most practical and long lasting available. They offer great security and protection to the building, and they are usually a reliable and worry free long-term choice. However time catches up with everything and rusted roof decks and leaks may start to compromise the building’s integrity.

With over 60 billion square feet of metal roofing in place in the United States and two billion more installed each year, that adds up to a lot of leaks – and a lot of money spent fighting them. When the integrity of the structural metal roof deteriorates, membrane retrofit solutions can provide a better option than replacing the metal roof or continuing to repair it. Membrane retrofits are a cost-effective, single-ply roofing solution that can usually be installed directly over existing metal roofs.

We offer the Duro-Shield Metal Retrofit Roofing System to protect the building against rain, temperature changes, interior drips, ice build-up, as well as rust and corrosion. Our prefabricated membrane is custom designed to fit the metal roof exactly, and is assembled in our factory, eliminating 80-85% of rooftop installation labor. This solution keeps Mother Nature outside, while your inventory, equipment, and workers stay safe and dry inside.

Roof Dilemma: Maintain or Replace?

maintainreplace4

Is roof replacement a better option than maintaining it when the roof’s watertight integrity – its primary function – fails? In other words, at what point do roof leaks become intolerable, and it’s time to replace the roof?

Think about how roof leaks can affect the bottom line:

  • Interior damage: To ceiling tiles, carpet, computers, gymnasium floors that could cost $500,000 to replace.
  • Production downtime: Shutting a line down for a day could cost thousands of dollars in lost productivity.
  • Lost business: Roof leaks at a four-star hotel can make the priciest rooms unavailable for guests.

Delaying roof replacement can add costs to a new roof project once the decision to replace it is made. Ineffective and inconsistent patching and other maintenance can allow water to penetrate the membrane and cause irreparable damage to roof system components, including insulation and the roof deck itself. Here are some potential added-cost considerations:

  • Tear off – add $1-2 per square foot.
  • Roof deck replacement – add $2.50-6.00.
  • Asbestos removal (possible for some older facilities) – add 10% or more.

The roof contributes – on average – 5% to the construction cost of a building, but is the most litigated component of a commercial building.

Building owners/managers should use their experience to establish a projected average service life of roofs. Several factors will influence a roof’s service life: design quality, installation integrity, products, maintenance, roof use, and weather.

Here’s an example: If you manage a million square feet of roofing that has a projected life expectancy of 20-30 years, you might consider budgeting to replace 1/20 or 5% (50,000 square feet) per year. If the average installation cost is $5 per square foot, look to budget $250,000 each year.

So when you are deciding between maintaining or replacing, look at your annual maintenance costs and if they are exceeding what your annual new roof budget is, it may be time to replace.

The Art Of Specifying A New Or Replacement Roofing System

Putting a new roof on a building is a major undertaking. Assembling the right team to plan and carry out the project can help ensure that the job proceeds smoothly, and that the finished product looks and performs up to expectations.

Who’s Involved?

An important first step is determining who to include in the decision-making process. While the exact titles will vary with each project, two individuals or groups are key. One is the employee most familiar with the current roof, any problems it’s been experiencing, and the solutions that have been used.

Not surprisingly, it’s also helpful to include the individual who will have final approval over the decisions to install the roof and the amount to be spent. Depending on the company, this individual may be the facility manager, building owner, purchasing manager, company owner, or head of finance.

In addition, roofing systems slated for installation on new construction often require the input of an architect or designer. Including them early on in the process helps ensure that all concerns are addressed up-front.

Another key member of the roofing team is, of course, the contractor chosen to install the roof. Facilities professionals evaluating contractors should consider the experience each contractor has with different roofing systems.

The Contractor’s and Manufacturer’s Roles

Before re-roofing begins, the contractor should complete a thorough investigation of the current roof and determine what, if any, problems have arisen.

The contractor also should ask the building owner or manager about any constraints the installers might face, such as, if there are times during which the noise that accompanies a roofing job would interfere with building operations.

Building owners and managers should also stay in contact with the manufacturer of the roofing system. If the contractor that installed the roof retires, for example, the manufacturer should be able to help the building owner locate another one.

Other Considerations

When a new roof is installed, the initial cost typically is top of mind for most building owners and managers. However, there are other costs that facilities managers should factor into roofing decisions. The warranty also plays a key role in the overall costs of the roof. What does it cover and what does it exclude? Some warranties cover damage to a building’s interior that results from a leaking roof, while others don’t.

Equally important to consider are the ongoing roof maintenance costs and its expected life. The less it costs to maintain a roof and the longer it lasts, of course, the lower the overall cost will be.

Assembling the right team, keeping the lines of communication open, and considering both the initial and long-term costs of different roofing systems help ensure a successful roofing project.
