The Green Shingle - Modular Green Roof for Sloped Roofs

[Viewed 135 times]

Green Roof - Overview
A green roof is a roof of a building that is partially or completely covered with vegetation and
soil, or a growing medium, planted over a waterproofing membrane.
Advantages of traditional intensive and extensive green roofs include:
1. Reduction in storm-water runoff
2. Reduction in heat loss in winter and reduction of internal building temperature
during summer
3. Attractive to look at and beneficial for wildlife
4. Improvement in sound insulation for buildings
5. Removal of carbon dioxide and absorption of pollutants from the air by plants
6. Cooling of air around roof by evaporation from vegetation
7. Protection of the roof from UV light – increasing life span (up to twice as long)
8. Potential to score more than 7 LEED credits under the US Green Building Council
certification system
Disadvantages of traditional intensive and extensive green roofs include:
9. Inability to be fitted or retrofitted to sloped roofs
10. Higher materials and installation costs than traditional roofing (5 to 10 times)
11. Stronger roof beams can be required to support extra weight
12. Higher maintenance costs
13. Complex drainage systems
The disadvantages of green roofs usually outweigh the advantages, limiting their use
primarily to expensive custom homes, large public buildings and corporate headquarters.
Another factor that has limited the use of green roofs is that a majority of new and
existing homes have sloped roofs, for which an inexpensive and easy to install system
is not available.
Sloped Green Roof System – The GREEN SHINGLE
The Green Shingle system offers a modular, sloped green roof system with all the
advantages discussed, without the disadvantages of traditional green roof systems.
Because the Green Shingle design is similar to a traditional roof tiles, installation and
maintenance requirements are very similar. The material and installation costs of Green
Shingles will be lower than traditional green roofs. The weight of the tiles, with growth
medium and sedum plants will total 10 pounds per square foot, the typical dead load
of a sloped roof. This enables existing homes and businesses to be re-roofed, and new
homes and businesses to be designed and built using Green Shingles, with no additional
construction costs. And because they will function like traditional roof tiles, complicated
drainage systems are not required.
Because there are no modular green roof systems available for sloped roofs, which are
more common than flat roofs, there is a large green roof market that remains under-served.
This presents and opportunity that is enhanced by Federal and State water quality control
and hydro modification standards that are increasingly strict. New development projects are
required to manage the quality and volume of storm-water runoff leaving the site. The Green
Shingle system is designed to be an invaluable tool in addressing these requirements

Financial information

Thank you for the opportunity to present my product idea, the Green Shingle.

I work for homebuilders and developers, mostly on housing projects. From single-family homes to apartments, most housing has sloped roofs. This is a massive green roof market, and no manufacturer has a strong presence in it.

However, homebuilders and developers are very conservative, and will be slow to adopt products that represent a dramatic change in function or aesthetics. For these reasons, I designed a green roof product that looks and functions like traditional roof tiles, or shingles, making it more relatable and acceptable to a broader base of customers.

I do not have the time or resources to bring this important product to the market, so I am looking for an outright sale of the patent.
