Recycled Asphalt Tear Off Shingles (RAS)

EnergySmart contractors are being encouraged to recycle any tear-off shingle waste from local projects...


Unfortunately, because of increased recycling volume of shingles, lack of space and limited market demand for RAS, Asphalt Specialties has closed down their recycling operations in Erie and at all their other Denver Metro locations as of 5/28/11, until further notice.

At this time, only Brannan Sand and Gravel, at 61st and Pecos, and Owens-Corning/Heritage Environmental at 64th and Pecos, both in Denver, are receiving tear off shingles for recycling.

New Opportunities for the Use and Promotion of RAS

Though Boulder County tear off shingle recycling operations are now largely curtailed by the shutdown of Asphalt Specialties local collection point, there are other encouraging developments for the eventual end use of RAS in large scale paving projects:

*In March of 2011 The Colorado Department of Transportation approved a revision of Section 401, Reclaimed Asphalt Shingles, which modifies CDOTs Standard Specifications for Road and Bridge Construction (in practical terms this means 10,000 to 20,000 tons of RAS may be used in CDOT approved paving projects this year).

*Asphalt Specialties has been awarded a contract to pave portions of State Highway 36 using a recycled asphalt pavement (RAP) and RAS mix design (the RAS portion shall be manufacturer scrap shingle stock in lieu of tear off shingles). More detail is provided below.

* A formal discussion with Lisa Friend and Jeff Callahan of Boulder County Resource Conservation Division and other recycling contractors occurred in April of 2011. This discussion helped with the gathering of initial information for a proposed feasibility study for the opening of a county Construction and Demolition Waste recycling facility which will include RAS and other construction material.

* The Colorado Springs Chamber of Commerce Sustainability Action Council brought a group of 40 – 50 members of their business community and local government to Boulder County in April with an aim to learn more about our sustainability practices in the public, private and non-profit sectors. This exchange brought about productive dialogue with our Colorado Springs counter parts and how best practices in Boulder County may be useful models for our neighbors to the south.

Other Recycling Opportunities: Commercial Roofing Material

Roof Cycle has been considering another recycling initiative in the area of single ply commercial roofing materials such as EPDM rubber membrane, PVC and TPO. Also under consideration for recycling is polyisonene and extruded and expanded polystyrene insulating foam. The asphalt from tar and gravel roofing also has potential end use.
RoofCycle is currently investigating the feasibility of initiating this type of recycling program for Commercial contractors.  This includes building a relationship with National Foam Inc., an entity with a recycling program and protocol to recycle the above mentioned commercial roofing products.  Additional research into the end use value, potential for local partners and sites, transport fees and overall cost effectiveness of such a program.
Overall, the green building industry has great momentum in the commercial building retrofit market and the potential for recycling opportunities for roofing products in this sector is both practical and well timed. It is also imperative that end-use for these recycled materials is established prior to development of the education and training portion of the RoofCycle model. RoofCycle education and outreach has been a key part of the success of RAS in Boulder County and there is potential for this momentum to continue into the commercial sector.

Moving Forward with the RAS Initiative in Boulder County

Recycling asphalt tear off shingles that come from the City and County of Boulder is now less practical due to the Closing of Asphalt Specialties collection point in Erie.
However, there will be some tear off shingle materials coming from Boulder County that go to either Brannan sand and Gravel or Owens-Corning/Heritage. Among those who will make an effort to recycle some loads are 3R Roofing, Van Lier Roofing and Haul Away Recycling and others.
Denver based contractors are still very active in their recycling efforts as these collection point locations are within reasonable distance of their job locations. As CDOT approves the use of RAS in more large scale road projects the value of this commodity will increase. Boulder County based collection points, with increased demand and the rising cost of asphalt based products will eventually see more movement of RAS out of current stock piles. In a matter of a few years and with CDOT actively supporting its use, RAS will be a common commodity in large and small scale paving projects in Colorado.
As this market matures, it will be practical to re-introduce a Boulder County administrative mandate and also to consider public/private partnerships for the collection and sale of asphalt tear off shingles for road paving.

Join the Movement for Roofing Best Practice! What is "Roofing Best Practice"?

Obviously we'd like to see every home have an energy efficient roof.  We'd like to see every home and building have a roof that is made from mostly recycled content and that won't summarily be dumped in a landfill.  We'd like to see this growing movement of green roofing move faster.  In the mean time, I offer the standards for Roofing Best Practice.
  • Recycle tear-off Shingles
  • Work with your City & County for project financing & rebates
  • Install Energy Star Roofing material
  • Use high recycled content materials - such as steel
  • Partner with Renewable Energy contractors
  • Ventilation upgrades reduce cooling load & extend roof life
  • Recycle other C & D waste
Thanks for your ongoing support.  And help us move toward recycling commercial roofing products too!

How Recycling Tear off Shingles (RAS) Will Lead to Recycling Single ply, BUR and Modified Bitumen

The fairly new and emerging story of recycling asphalt tear shingles (RAS) is one of roofers and others rising to the level of expectations in a specific municipal construction culture. How does this come about? Here is RoofCycle’s short story:
After joining the Boulder Green Building Guild in 2004 I instantly recognized the dominant issue in the residential roofing industry as diverting the huge volume of asphalt tear off shingles from local landfills and finding an end use for this material.
Subsequently, Roofs to Roads Colorado was created with the help of our associates and state and county grant funding. This launch, in 2009, resulted in roofer trainings for proper recycling protocol and shingle delivery to qualified collection points and advisory relationships with the Colorado Department of Transportation, local HMA contractors, municipalities and others.
Shortly after its start in 2009, Roofs to Roads Colorado found allies and like minded roofing contractors in Brickey Construction, Colorado Exteriors, Academy Roofing and others and through this partnership we were able to create an important collection point and training center through Brannan Sand and Gravel in the north Denver metro area.
Well over 100 roofers and haulers are now recycling RAS in the Denver area and this not only benefits their bottom line as recycling costs ½ as much as landfill tipping fees but we are seeing significant landfill diversion and the resulting CO2 reduction when RAS replaces a portion of the virgin binder in the pavement mix. And, roofers engaged in the ‘Best Practice’ of recycling are more often preferred by their customers who want responsible stewardship in their roofing contractors.
Asphalt tear off shingles are the material ‘most likely to be used in recycling’ at this point. Clearly, its value as an oil based product in paving mix designs and the huge volume available make it one of the darlings of the C and D waste recycling industry.
However, there is a fledgling market developing for commercial/industrial roofing materials such as modified bitumen, EPDM, TPO, PVC, tar and gravel and others. As interest and resources have been invested over the last decade for the recycling of asphalt tear off shingles, a momentum for other Best Roofing Practice (BRP) and sustainability has been created and subsequently the basic infrastructure is being developed to recycle these other commercial roofing products.
 National Foam Inc. (NFI) has recently developed a basic recycling program to collect EPDM and other single ply membranes as well as roof insulation from commercial roof demolitions. This recycling effort is one of the first of its type in North America and because of the large volume of commercial roofing C and D waste on this continent  there is much opportunity and need for the creation of greater infrastructure to process these materials as this will be a ‘game changer’ for long term sustainability in the commercial roofing industry.
To that end, RoofCycle is partnering with associates in Denver, Colorado to develop a drop off center for commercial roofing materials. At this time the start up for this pilot collection center is dependent on projected state grant funding and other sources to be determined.
Recently, the City of Denver partnered with NFI for the recycling of ballasted EPDM on several City specific projects which had LEED requirements for recycling such material.
 We believe that the recycling of commercial roofing materials, as is evident in the tear shingle recycling initiative, will provide significant cost savings for roofing contractors as they recycle instead of dumping this material. And we will see reduced landfill use and the corresponding reduction in GHGs as these materials are used instead of virgin materials by end users in roof material manufacturing and other industries.
Also, importantly, engagement with local municipalities is a key component in the creation of any roofing material recycling program and the implementation of the other concepts of Best Roofing Practice (BRP). A case in point is the RoofCycle/3R Roofing collaboration with the Boulder County Build Smart Program and the grant support of Boulder County Resource Conservation Division:
To help Boulder County achieve its goals in the Zero Waste Action Plan, in working with Build Smart, RoofCycle has conducted trainings for recycling tear off shingles and BRP at the Boulder County offices over the past year. These trainings are important for creating the cultural shift in handling C and D waste and approaches to BRP that is needed for the ambitious Zero Waste and Co2 reduction goals of Boulder County. 
Well, maybe that was not as short a story as I intended but there are many factors to consider in the newly emerging Best Roofing Practice.
In closing, I encourage you to take a look at Roofpoint: This is a guideline created by the Center for Environmentally Innovative Roofing (CEIR) which is an associate arm of the National Roofing Contractors Association (NRCA).
Roofpoint is a similar approach to Leadership in Environmental and Energy Efficient Design (LEED) as it specifically applies to commercial and residential roofing. These guidelines provide numerous specific approaches to sustainable Best Roofing Practice (BRP): among them is the use of reflective roof membranes and coatings (Energy Star and Cool Roof products) and recycling of demolition materials. Look for CEIR to roll out their new guidelines at the upcoming International Roofing Expo in Las Vegas, February 16-18, 2011.

DOE Grant funding: Sun Sales Means Roof Sales!

Say what?
Well, when our friends, the PV solar electric contractors, make sales, it invariably leads to roofing sales. Most photovoltaic systems are roof mounted and at least 50% of these roof systems need replacement before PV systems can be installed. For those roofers who do not already have solar contractor partners or are not involved doing PV yourselves, I say develop this part of your business – soon!
 Now, if you do any work in Boulder, Denver or Garfield counties – and I would say this applies country wide under any circumstances no matter what kind of funding is available - you have an extra special reason to take interest in PV solar electric and building envelop insulation.
  New Department of Energy (DOE) grant funding is coming to these counties in Colorado for micro loans that will apply to energy efficiency upgrades in the categories of renewable energy (i.e., PV solar electric etc.), insulation upgrades and other categories to be announced. Though material and labor other than roofing related insulation and Energy Star roofing specifically, does not qualify for these micro loans, it is a good bet that these ‘second tier’ upgrades will get traction as the qualifying categories see much upcoming customer demand for ‘related work’.
  So, for roofers who do work in these Colorado counties, get ready for extra demand for your services come 2011. And, also know that your work with PV solar contractors and energy efficiency contractors will help reduce collective consumption of coal and other non-renewable energy at local utilities.
 Finally, it is an extra bonus when you recycle your asphalt tear off shingles at the various Denver metro collection points for recycled tear off shingles (RAS). You will also be doing your part for landfill diversion, CO2 reduction and supporting the birth of a transformative industry that is beginning to use RAS as a substitute for virgin asphalt binder in road paving mix designs.
