367 <br /> <br /> Mr. Mercer asked Mr. Hill if pressure-treated shakes for <br />shake roofs are treated on both sides and if they are effective <br />fire retardants. He also inquired if shake roofs can be treated <br />and what the cost difference is between regular shake and <br />pressure-treated shake roofs. <br /> <br /> Mr. Hill replied that treatment of pressure-treated shakes <br />goes into the wood itself and are effective fire retardants, rated <br />"A", "B" and "C". Non-rated roofs that are treated have a <br />reported degree of fire protection, but these are not rated by any <br />agency. Actual cost of materials, installation and labor for <br />ordinary shake roof is approximately $210 per square foot; Class <br />"C" is $215 per square foot. <br /> <br /> Mr. Mercer asked Mr. Smith if a new structural support inside <br />the roof would be necessary to have a new tile roof. <br /> <br /> Mr. Smith answered that it would depend on how the house was <br />originally built. It usually needs some type of bracing. <br /> <br /> Mr. Mercer asked for a cost differential on the different <br />types of roof work: tile, metal and pressure-treated. <br /> <br /> Mr. Smith replied that the permits issued for tile roof <br />require some bracing, the price of which is usually included in <br />the price of the roof work. In general, composition Class "C" <br />roof is the least expensive, followed by shake, metal, and tile. <br />Tile roofs cost about $1,500 to $2,000 more per house. <br /> <br /> Ms. Mohr commented that longevity is a variant on each of the <br />products; a more accurate way of comparison would be to use a <br />cost-per-year breakdown. <br /> <br /> Mr. Smith stated that wood products do not last as long as <br />the others. <br /> <br /> Mr. Mercer mentioned that he was in favor of this but is <br />concerned about costs, although $5 per square foot is not too <br />expensive for a lifetime fire-proof roof. <br /> <br /> Mr. Butler indicated that he was opposed to requiring Class <br />"C" roof because the costs are widely divergent and creates an <br />unnecessary intrusion in the property owners' ability to work on <br />his own property. <br /> <br /> -16- <br /> 10-3-89 <br /> <br /> <br />
