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

Durability of roofing materials
The Romans knew a few things about sustainability
and energy efficiency
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 materials
Reroof jobs account for 69% of national demand

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)
Source: Shinglerecycling.org
A huge waste...asphalt shingle disposal
11 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 life of roofing material…how the air is affected
The BEES® Lifecycle Assessment quantifies the environmental
smog impact from different roofing materials
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:
Phoenix, AZ

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

Water Run Off that Helps Your Garden Grow…

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.
