RE: Roof Shingle Impact Resistance Follow-up Memo
The purpose of this memo is to provide answers to follow-up questions from Councilmember
Cunniff in response to the memo about roof shingles dated 9/25/18.
Question: I think most people understand that there is no such thing as a "hail-proof"
roof. Anecdotally, though, people are seeing very significant reductions in their
homeowner’s insurance premiums when they install Class 4 roofing.
Please analyze the net cost or benefit to homeowners of installing Class 4 roofing;
and please also include an estimate of recent impacts to landfill capacity from
disposed shingles.
1. The cost increase for an average size home to install Class 4 shingles is $500 - $1000.
Most home insurance companies provide a discount on insurance rates when Class 4
shingles are used. The typical range for this discount is 10%-30%. In our hail prone area
State Farm and Farmers Insurance give a 28% discount and estimate that the higher
initial cost of the Class 4 shingles is recouped by the homeowner in approximately 2.5
years. While we don’t have additional data, it seems likely that the reduction in insurance
premiums and reduced frequency of roofing replacements result in a long-term financial
benefit to homeowners.

2. According to the Solid Waste Director for Larimer County, construction and demolition
materials normally make up 30% of the volume at the landfill. This number has increased
to approximately 50% due to the increase of shingles from recent storms.
3. Building Services and the Building Code Review Committee are recommending for
Council Adoption in December three additions to the local code related to this topic:
o A requirement that all structures choosing to install asphalt shingles to use Class
4 impact resistant shingles, and
o A requirement for reroof projects to report the amount of waste and final waste
location.
o A requirement for roofing permits to submit a final construction waste
management plan.
While the builders/developers are concerned with the additional upfront cost of Class 4
shingles, they did agree this is a prudent choice for reducing waste and some builders
are already installing Class 4 as normal practice.
4. According to Environmental Sustainability staff Jonathon Nagel, data on the amount of
disposed roofing materials is currently not gathered as part of the City’s waste tracking.
Roofers will often haul their own materials to the landfill and, unlike licensed haulers, they
are not required to report that data. Additionally, a construction waste management plan
has not been required for roofing permits.
5. While it is possible to use asphalt shingles to produce reclaimed asphalt pavement,
currently there are no facilities in Northern Colorado that recycle them. The City does not
accept asphalt shingles at the Hoffman Mill Crushing Facility due to equipment limitations
and cleanliness of materials including concern of Asbestos used in certain shingles. A
proposed County-owned construction and demolition debris sorting facility may lead to
regional end-market development for these materials.
