Roofing Guidelines


THOA Roofing Material Guidelines and Requirements

(Revised March 2020)


General Roofing Guidelines:

      Roofs in Tiffany should have dimension to create the appearance of layering and variable depth.  To help achieve this goal, the following guidelines apply:

  • Roofing material must have dimension to create an appearance of layering and variable depth.
  • Flat materials with no vertical relief are prohibited.
  • The sole use of shading of such product to create the appearance of height and shadow is prohibited.
  • The color of the roofing product should be compatible with and complement the exterior color of the residence.
  • Class 4 impact resistant asphalt products of sufficient thickness will be considered for approval so homeowners can take advantage of discounts provided by some insurers.


Specific Material Guidelines or Specifications:

The desired visual quality and character may be achieved through a variety of materials. Each proposed roofing project will be subject to approval by the ACC, even if the homeowner wishes to install a preapproved product.  Even a preapproved product is subject to rejection if it appears to the ACC that the manufacturer has changed the product.


Shakes: If you choose to use wooden shakes, tapered western red cedar shakes, sawed or split, are the preferred roofing materials. Shakes shall have the minimum thickness of a “medium shake” with an exposed end nominal thickness greater than 9/16 of an inch.

Acceptable materials: Medium thickness cedar shakes, used as patches or an entire roof

replacement, oil treated or untreated, unstained, natural in color, allowed to weather to a grey, dark grey, or dark brown appearance.


Asphalt-Fiberglass Composite Shingles: Dimensional, non-flammable, asphalt shingles, having the following minimum standards:

  • a minimum weight of 350 lbs per square
  • displacement (thickness) at some intersections of at least 3/8 inch
  • a 50 year or limited lifetime warranty

Acceptable materials: Roofing materials and colors that mimic weathered shakes are preferred (medium to dark gray or medium to dark brown).

 Colors:  Subject to the ACC’s evaluation and approval.

The ACC evaluates all roofing proposals and approval is not guaranteed even if it meets all of the above minimum standards.


Preapproved asphalt products:


New Preapproved asphalt products as of March 2020:



Other Materials: Other alternate, non-flammable materials such as steel or advanced plastics may be considered on a case-by case basis and are not specifically excluded by these guidelines. The homeowner will need to prove to the ACC that such materials and colors are visually acceptable, highly durable, and in use in this region of Colorado.


Acceptable materials: Simulated shake like materials are required.

Preapproved Products (non-asphalt):

  • Da Vinci shakes, Colors: Autumn Blend (
  • Gerard Stone-Coated Steel, Canyon Shake, Colors: Timberwood, Ironwood, Windsor (
  • Concrete Tiles, Oldcastle 50 year flat slate tile in burnt cedar color by Westile, Inc. (
  • Concrete Tiles, Saxony Shake by Boral, most colors are acceptable



Submittal Process:

The homeowner must submit a request for approval of any roofing project (including roof replacement) to the ACC in writing prior to commencement of the work. Homeowner is advised not to make a contractual agreement until the ACC review process is complete. A minimum of one week (for previously approved roofing products) is needed.

Alternative or new roofing products must be submitted a minimum of 30 days in advance of the anticipated start date. Evaluation of new roofing products, particularly those not in common use in the local area, may take an extended period of time and the homeowner should be prepared to provide sufficient proof and reference material to allow the ACC to make an informed decision. The research and proof should include written manufacturer’s descriptions or specifications and actual sized samples.  A local example (i.e. a home within 5 miles) should be identified with the proposed new materials for view by the ACC.  Upon request of the ACC, a presentation by the homeowner and manufacturer or installation contractor to the full ACC committee will be required.

Insufficient information submitted may be a basis for rejection. All approved roofing projects will include a written statement by the ACC as a record for the homeowner and ACC’s files. As with any project, no verbal approvals will be provided.

Notice: The ACC, Board, and THOA cannot and does not provide or imply any sort of endorsement or warranty for the roofing materials and products listed. The homeowner is solely responsible for the installation and maintenance of any roofing product and will be held responsible for the replacement of any roofing product that shows significant degradation or failure for any reason over its lifetime. We suggest that homeowners seek installers that are certified by the roofing manufacturer for quality, performance, and optimal warranty issues.
