Roofing Guidelines 2015

Description

ROOFING GUIDELINES SECTION I FIRE-RESISTIVE REQUIREMENTS FOR ROOFING Pitkin County no longer allows wood shakes or shingles to be installed on homes in Starwood, regardless of whether it is a new home or a home which already has wood shakes or shingles. There is a fine line that determines the point a “roof repair” becomes a “re-roof” and is subject to requiements for a roofing permit and compliance with the new requirements. Any licensed roofing contractor should be able to make that determination and advise a homeowner. Pitkin County has implemented 1041 Hazard Reviews for all projects in Starwood, and one of the risks evaluated in the 1041 review is wildfire hazard. County staff explains that Starwood is generally mapped as being in the “Low / Moderate” classification as regards wildfire hazards, but there is no objective, concrete mapping of: 1) which lots are rated as “Low / Moderate” and, 2) which lots are rated as “Severe”, the next higher classification. Each lot is evaluated by a County staff person at a site inspection based on its specific slopes, exposures, native and irrigated vegetation, and so forth. The initial assumption is that Starwood lots are usually “Low / Moderate” unless it has the combination of risk factors which, according to the Colorado Department of Forestry Guidelines that the County uses as a reference, it would fall into the “Severe” classification. A homeowner or architect will not know the exact wildfire classification or preventative requirements until the 1041 site inspection has been completed, but that is a relatively simple process to go through, at least for small additions. New homes are another matter. There are, however, guidelines for types of fire-resistive construction that will be required, depending on the wildfire risk classification: WOOD SHAKE AND SHINGLE ROOFS ARE NO LONGER ALLOWED BY THE COUNTY MARK NOEL - STARWOOD ARCHITECTURAL ADVISOR Starwood Homeowners Association | (970) 379-3778 | mark@mnarchitect.com Starwood\Forms\Roofing Guidelines 1 2015 v. 1_ 2015.11.20 A roof construction consists of two types of fire resistive classifications; ratings or classifications for the materials alone, and ratings or classifications for the overall roof assembly. • A roof material may be combustible [e.g. wood shakes, asphalt or composition shingles, etc.] or non-combustible [e.g. metal roofing, slate, cement tiles, etc.].
