Tile Roofing in the US Market

Environmental Impacts, Life Cycle and Sustainability

What is the significance of a roof?Sustainability from a product lifecycle perspective

Long Lifecycle - Through using products with durable material, sustaining the life of the structure

Save Energy - Through innovation and conservation

Reduce Waste- Through recycling and waste diversion

Reduce Pollutants, Toxins, Carbon Emissions- By encouraging or requiring responsible manufacturing practices- Use of products with little environmental impact

Utilize Local Resources- Minimize need for long distance transportation of products

What is the significance of a roof?Thinking about roofs is more than just about leaks

The U.S. is unusual in comparison to other developed countries in the use of “Oil based” roofing materials

The US Pitched Roof Market…Asphalt shingle dominates the market with 69% market share

This is a 2000 year old section of the roof of the Roman Bath House in

Bath England where the hollow bricks were used to retain the natural heat

from the hot spring

Durability of roofing materialsThe Romans knew a few things about sustainability and energy efficiency

Asphalt Shingle

50+ years

Few States have provisions for recycling asphalt shingle…Unfortunately, most of the waste ends up in landfills

Allow manufacturer’s RAS only

Allow RAS (including tear-offs)

A huge waste...asphalt shingle disposal11 million tons of asphalt shingles are generated in the US per year

Reroofing jobs account for 10 million tons of asphalt shingle, with another 1 million from manufacturing scrap.

Compared to 140 million tons of concrete that are recycled annually in the United States alone.

“The average home contains about 3-4 tons of roofing shingles which is over 6 barrels of oil…”

The primary pollutant from the Asphalt Shingle LCA is Nitrogen Oxide.

Can a roof improve air quality………..The highest concentrations of ozone in the US are found in California, Texas, Nevada, North Carolina and South Carolina

The American Lung Association “State of the Air 2011 report” shows the 10 regions with the highest concentration of ozone:

We need to care for the people at greatest risk, such as:

Children who grow up in areas of high smog pollution may never develop their full lung capacity as adults

People who work or exercise outdoors

People with lung disease, especially chronic lung diseases such as asthma and COPD

Senior citizens

Why do we care… Smog irritates and inflames the lungs like a “sunburn”

14Source: http://www.lungusa.org/healthy-air/outdoor/resources/ozone.html

There are two possible parallel paths for the improvement in air quality: the continuing reduction of pollutants at source and air purification

The Formation of Smog…

During exposure to sunlight, smog is formed when Nitrogen Oxides (NOx) in the atmosphere combine with Volatile Organic Compounds (VOCs).

NOx: Carbon-containing compounds released by the evaporation of petroleum products, or carcinogenic compounds like benzene and butadiene.

VOCs: During exposure to sunlight, smog is formed when Nitrogen Oxides (NOx) in the atmosphere combine with Volatile Organic Compounds (VOCs).

“Air pollutants generated from motor

vehicle traffic contribute to the formation of

ozone that is known to be harmful to human

health…”

How Does it Work?

Smog Eating Tile oxidizes harmful, disease-causing NOx, helping clean the air so that it is safer to breathe.

This revolutionary roof tile includes a coating with the key ingredient Titanium Dioxide, a photocatalyst. The photocatalyst is activated by the UV content in daylight. The active surface interacts with harmful Nitrogen Oxides in the air and helps convert them into Calcium Nitrates.

Naturally occurring and safe for humans, Titanium Dioxide (TiO2) is commonly found in toothpaste, cosmetics, household paint, and many other items we interact with daily.

Titanium Dioxide’s de-polluting and de-soiling capabilities are proven. The notable European Union PICADA Project study demonstrates the capabilities of TiO2 as a key ingredient in coatings.


A Proven De-Pollutant. How do we know it works?

Over one year, a 2,000 square foot BoralPure™ Smog Eating Tile roof can oxidize the same amount of Nitrogen Oxide as a car produces from being driven up to 10,800 miles.

“The real impact is that it takes that car off the road.”

Measurable Results…Reduce Your “Smog” Footprint

INTERNATIONAL STANDARD ISO 22197-1

Fine ceramics (advanced ceramics, advanced technical ceramics) — Test method for air-purification performance of semiconducting photocatalytic materials — Part 1: Removal of nitric oxide

In addition to providing nutrition for plants, calcium nitrate has a restorative effect on soil. The calcium nitrate residue, which reaches the ground as rainwater runoff over the course of time is in small concentrations which are less than the concentrations found in normal lawn and plant fertilizer used over that same time period.

Source: The calcium nitrate concentrations may vary depending on weather conditions including the frequency and intensity of rainfall, geographic location and other factors, including but not limited to the concentration of nitrogen oxide in the air. http://soil.gsfc.nasa.gov/soilfert/npk.htm
