Instead, tiles can besecured with screws and/or a chemical bondingagent for greater performance. Tiles can beexpensive, and their increased weight requiresstronger structural support.Sheet MetalSheet metal roofs is available in a variety of colorsand profiles, although a galvanized finish withlow ribs is the most common. Sheet metal isgenerally approved for roofs as low as 2:12, withspecial underlayment. More expensive standingseamvarieties can handle roof pitches of 1:12.Most sheet metal roofs are warrantied for 30years or more, but can last much longer. Thoughhistorically as much as twice the price of asphaltshingles, the price can become comparabledepending on larger market factors, such as theprice of oil. A metal roof reflects more light thanasphalt, saving on cooling bills. Sheets are verylightweight, and resist high winds better thenshingles.Green RoofGreen roofs comprise of a water barrier attachedto the roof decking, over which planting mediumsuch as soil and appropriate vegetation areplaced. Green roofs collect rainwater andmoderate interior temperatures. They mustbe detailed well to prevent water penetration.Green roofs are generally unused in hurricanezones or areas with heavy downpours, so furtherconsultation and study is necessary.RubberRubber roofs, or EPDM membranes, consist ofa wide rubber membrane glued to a substrate.Rubber roofs are common in commercialconstruction, but can be appropriate for flat orlow-pitched residential roofs as well. If detailedproperly, they will not leak, but precise installationis imperative. Rubber roofs can last more than 20years. They are relatively inexpensive, but as theyare usually black and absorb a significant amountof heat, increase cooling costs.FURTHER INFORMATIONwww.toolbase.orgwww.gccds.orgOTHER TYPES OFROOF SYSTEMSRoof Systems small assembly systems
