Roofing conferences to push for greater energy efficiency, roofs are being aske to do more. Originally, roofs were only envisioned to provide a setting for HVAC systems. But new regulations are asking roofs to do more than that. With the ENERGY STAR(c) labeling program, roofs can be rate base on their reflective properties. This new program is gearing up the industry for debate about the adde benefits.
Roof System Selection
The guide to roof assembly materials covers the primary components of a roofing system, including roof decks, air and vapor retarders, insulation, and roof coverings. It covers application criteria for selecting a roofing system and includes information about warranty and construction contract administration. It includes information on emerging issues, relevant codes and standards, and additional resources. Despite the fact that it is written for a roofing contractor, this guide is still a valuable resource for those responsible for building roofs.
For instance, the roofs of a single-family home can be as energy-efficient as an eight-story skyscraper. The two primary types of roofs have their own advantages and disadvantages. In a building, a thin-film EPDM roof may be better than an insulated white TPO roof with four inches of insulation. White TPO roofs may be a better choice for the Energy Efficient Roofing Conference due to their superior durability and reliability.

Non-Destructive Evaluation
Before implementing an NDT&E project, it is essential to review all the facts. There are many types of non-destructive evaluation, including infrare thermography, electrical capacitance, nuclear detection, and moisture probe. Each technique has its advantages and disadvantages. For example, infrare thermography allows technicians to inspect the entire roof instead of a 10-foot-square grid pattern.
The primary purpose of non-destructive evaluation for energy-efficient roofing is to identify areas of wet insulation. This method is particularly useful for identifying leaky roofs before interior leak conditions show up. It also identifies areas where there is wet insulation, which can reduce value and energy costs. If wet insulation is found, it is essential to address the problem as early as possible. Roof Maintenance Systems can help you choose the most effective insulation for your building.
Fastener Pullout Tests
The National Roofing Association (NRCA) has performe limited nail pullout tests for various types of plywood and OSB roofs to determine the influence of sheathing thickness and fastener type on the resistance of the roof. PDF files require Adobe Acrobat Reader, which is free from the Adobe website. PDF files are not the same as print versions. When viewing a PDF file, the font size is a bit smaller than when printe.
ANSI/SPRI FX1 requires contractors to conduct 10 pullout tests for roofs up to 4,650 square feet, and five tests for every additional four thousand square feet. For smaller roof areas, one pullout test per 230 square feet or 2,500 square feet is sufficient. The contractor should test each type of fastener in accordance with the manufacturer’s specifications. If the pullout resistance does not meet the required level, he should not proceed with the roofing project. Instead, he should install additional fasteners to achieve the required resistance.
The ASTM E 1592 test is the key test use to evaluate the structural performance of roofing systems. It requires that the roofing system return to its original state after a certain amount of pressure is applie. If it does not, it has suffered damage. The allowable uplift pressure is calculated by using a safety factor, typically 2.0, and then compare to the design wind pressure.

Life-Cycle Cost
Life-cycle cost analysis has become a valuable tool for the construction industry. This technique measures the value of a product over its entire service life. It has also been using to market roofing materials. It compares the long-term costs of different products, including the initial cost, routine upkeep, and associated maintenance. These costs are normalize to the net present value (NPV) to eliminate inflation. The life-cycle cost of energy-efficient roofing is less expensive than conventional roofing materials.
One of the main factors that affect energy efficiency is the amount of insulation provide. There are various ways to achieve the require amount of insulation, which Total R-Values indicate. Changing insulation, sarking material, air films, and roofing covering will provide the required R-Value. The life-cycle cost of energy-efficient roofing is based on these figures. This analysis takes into account the costs of maintenance, installation, and repair.
The study compares the cost of a concrete roof with a PV rooftop. It compares the electricity generated by solar panels to that produced by a concrete roof. The cost of the PV rooftop was also estimated using a simulation. The simulation used BLCC software (a software package developed by the US Department of Energy). Results showed a significant improvement in the LCC. In addition, the savings outweighed the investment in the PV roof and the discount payback reached about 15 years.
Reflectivity
The energy-efficient shingles industry is gaining momentum with the growing popularity of ENERGY STAR(c) certification for new and existing roofs. With the energy efficiency of roofs on the rise, the industry is gearing up for an important debate about reflective roofing properties. One way to measure reflectivity is to measure how dark a roof is. If a roof is black, it would have a reflectivity of zero. Alternatively, a white roof would be 85 percent reflective.
The annual IRE conference is a great way to learn more about the latest technologies and best practices for roofing. In addition to educational sessions, IRE will host networking opportunities. This conference is the only one of its kind that brings together both construction and roofing experts, allowing them to learn about the latest trends and technologies. This conference is the ideal place for both professionals and consumers to learn more about energy-efficient roofs.
The benefits of a cool roof are clear: it reflects more sun’s heat, resulting in a lower building temperature. Conventional roofs can reach temperatures of 150 degrees Fahrenheit, while reflective roofs typically stay 50 degrees cooler. This means more comfort for occupants in buildings without air conditioning. A cool roof also reduces the flow of heat into the occupie space. Most cool roofs have a high thermal emittance, which means they shed heat by giving off thermal infrared radiation.
Green Roofs
The Energy Efficient Roofing Conference is fast approaching, which means green roofs are gearing up for an event that will highlight the latest innovations in this field. From sustainable, low-maintenance materials to advanced irrigation techniques, green roofs are gaining ground in the competition. The growing popularity of green roofs is reflecte in the recent emergence of several new types of green roofs.
To attend, green roof experts are gathering in Raleigh, North Carolina, to discuss the latest developments in this field. They will host a symposium, which will feature speakers and a small trade show for green roof and wall companies. Attendance at the event is free, and registration for the event is open to the public. A list of speakers will be available shortly. And, with the energy efficiency of green roofs and walls in the forefront of industry discussions, the conference will highlight the latest trends in green roofing and green walls.
The NPS website asserts that green roofs increase R-value, which reduces the load on HVAC systems, resulting in energy cost savings. Energy efficiency experts estimate that three to four inches of dirt can provide the equivalent of R-1 insulation to a single-pane window. However, the same amount of dirt is only R-0.5 if it is wet. Fortunately, green roofs have many other benefits, and we’re gearing up for the Energy Efficient Roofing Conference!
