Tax Incentives for Green Roofing

About green construction tax incentives

There are numerous state government and power company programs, rebates and incentives to make choosing sustainable products and practices fiscally rewarding and to induce designers and building owners to adopt green strategies for their facilities. Some of the most financially rewarding of the state and local power company programs can be found at the website:


Additional programs

In addition to the programs that vary from state to state and power company to power company, there is also a federal tax deduction available through the Internal Revenue Service for commercial property owners. This tax deduction is for commercial property owners who bring their property up to a minimum level of energy efficiency or even greater. Enacted in the 2005 Energy Policy Act, this federal tax deduction is only for buildings that were retrofitted after December 31, 2005 and prior to January 1, 2009.

The qualifying building must have reduced energy costs resulting from the building's heating, cooling, ventilation, hot water and interior lighting by 50% from a reference building meeting the minimum requirements of ASHRAE 90.1-2001 Standard.


The amount of the deduction is $1.80 per square foot of conditioned area if the 50% improvement is documented. Lesser deductions are available up to $0.60 per square foot if the energy improvements reach a minimum level of 16 2/3% above the reference building mentioned above. The Department of Energy also lists acceptable computer programs that can be used to calculate and verify the energy improvement. It is unknown whether this tax deduction will be extended beyond January 1, 2009 at this time.



Energy Efficiency for Roofing

At CentiMark, we demonstrate conscious regard for the environmental impact of our materials and roof systems.

A more Earth-friendly facility with CentiMark's green roof and energy-efficient solutions

By utilizing reflective roof materials, Urban Heat Island effect may be reduced. Through effective and economic recycling of roof materials, the waste sent to landfills decreases. To reinforce our commitment to the environment, we recycle in our office locations. That includes paper, toner cartridges, glass, plastic bottles and aluminum cans.

Our technological innovations and web-based initiatives help create a paperless roof repair reporting system. Before and after photos, invoices, work orders and other documents can be viewed online and printed on paper only when required.

CentiMark recognizes the importance of conservation, energy efficiency, green roof solutions and recycling. Our continued commitment is to do our best to work with roofing solutions that benefit our customers and our world, today and into the future.




Protect your building with energy-efficient options

CentiMark provides a highly reflective roof coating that has excellent elongation, tensile strength, UV resistance, low temperature flexibility and superior adhesion.

Form and Function: Black roofs are coated to provide an attractive white surface that reflects heat and sunlight. 

Waterproof: The coating is a three-step application providing additional water resistance to the existing roof system, flashing and penetrations.

Energy Savings: Cooler roofs may reduce a facility's utility bills and electrical demands. Coatings help protect your roof and may reduce maintenance costs. 


Title 24 Overview

What is Title 24?

The California Energy Commission (CEC) created regulations to reduce California's energy consumption and provide Energy Efficiency Standards for residential and nonresidential buildings - formally titled "California Code of Regulations, Title 24, Part 6." The Cool Roof update adopted in 2005 further sets cool roof energy standards for design and construction of roofs in California. This regulation added a prescriptive requirement for non-residential buildings with low slopes.

What does California Title 24 Part 6 now require?

Prescriptive requirements to install roofing materials that have an initial solar reflectance of 0.70 or greater and an initial thermal emittance of 0.75 or greater. Aged reflectance and emittance values will become the standard for compliance in the future.

What buildings are affected?

All Low-Slope (< 2:12) non-residential roofs over conditioned spaces (heated or cooled) that are new construction or are an existing building and is being re-roofed that has a re-roof area of 2000 square feet or more or the amount of the area of the roof to be re-roofed is 50% of the total roof area. If these conditions exist, then compliance to Cool Roof Prescriptive Requirements is mandatory. Note: The rules are a little different for both high-rise residential buildings and hotels.

Are there exceptions?

Yes. If an existing non-residential building roof is a BUR or Modified Bituminous roof with a rock or gravel surface, no removal of existing layers or installation of insulation is contemplated and there is no recoating with liquid applied coatings contemplated, then reflective roofing is not required.

How will this be enforced?

Evidence of compliance is determined by providing labels of the CRRC-rated products that are proposed when applying for a building permit. Non-complying roof systems will not be acceptable and do not allow the permits to be issued.

What is a CRRC-rated product?

CRRC is the Cool Roof Rating Council - an independent and unbiased organization that establishes test criteria for compliance to Title 24. CRRC is also a clearing house for verification and dissemination of this information. Specific labels showing compliance to Title 24 requirements are licensed to the manufacturers' of materials that have undergone testing to CRRC protocols. These labels show the reflectivity and emissivity values for the tested roof product.

Can CentiMark provide CRRC-rated products?

Yes, we do use various TPO and PVC membranes that are Title 24 compliant materials. In addition, some of the white coatings used over SPF are also Title 24 compliant.

Are there minimum insulation requirements in Title 24 besides CRRC-rated roof products?

Yes. Depending on the location of the building in California, minimum U values have also been established for compliance to Title 24.



LEED Information

What is the LEED program?

LEED is an acronym for Leadership in Energy and Environmental Design.

Who administers the LEED program?

LEED is a program sponsored and administered by the US Green Building Council.

What is the purpose of LEED?

LEED provides a rating system that incentivizes designers and builders decision to choose "green" building products for the construction and operation of buildings.

How is a LEED credit obtained?

LEED provides a set of widely accepted criteria as guidelines for choosing "green" products. Selecting "green" products over more traditional ones can provide LEED credits.

What is a "green" product?

Technically, a "green" product is one that has minimal impact to the environment. Green products are factors in designing for sustainable development.

What is meant by "sustainable development?"

Sustainable development meets the needs of the present without compromising the ability to meet the needs of future generations.

Are building products the only way to obtain LEED credits?

No. How and where the site is selected and used as well as how the building affects the surrounding microclimate's environmental conditions account for some available LEED credits

Does CentiMark use products that can qualify for a LEED credit?

Yes. Reflective roof membranes and coatings qualify for a LEED credit. Depending on recycled content, some products may be eligible for additional LEED credits such as wood fiberboard, ISO, or EPS. Amounts of insulation above that required by code can be seen as an additional LEED credit. Depending on the facility's location, products used from manufacturing locations within 500 miles of the job site may also be considered for a LEED credit.

What is a LEED certified project?

A LEED certified project is one that has submitted documentation to the LEED Steering Committee for verification of the total number of credits allowed by LEED guidelines for certification. A minimum of 26 LEED verified credits is required to be awarded "certification" status for New Construction and 39 LEED credits for Existing Buildings.
