Slate Roof longevity— slate roofs can and should be routinely built to last at least a century. In fact, 150 years is a reasonable expectation of a roof’s longevity if the roof is properly constructed. That’s a big plus in an industry where many roofing systems are lucky to last 20 or 30 years before needing replacement.
Roof Types Roof shapes differ greatly from region to region. The main factors which influence the shape of roofs are the climate and the materials available for roof structure and the outer covering. Roof terminology is also not rigidly defined. usages vary slightly from region to region, or from one builder or architect to another. When building
The picture below shows the pitch of a 7-12 roof slope meaning that for 12" of horizontal measurement (roof run) the vertical measurement (roof rise) is 7". This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement.
Roof pitch is expressed as rise over a 12 inch run, for example 4/12. Finding the pitch of a roof can be done by finding the rise and run, or converted from the angle if it is known. See the chart below for some examples of common roof pitches.
How roof pitch determines suitable roofing systems Flat and nearly-flat roofs (a pitch of 1-in-12 or 2-in-12) cannot be covered with shingles or shakes of any material since there is not enough angle to combat the danger of blow-off.
Roof pitch is often expressed as a ratio between rise and run in the form of x:12. For example, a pitch 1:12 means that per every twelve yards of building length the rise will be equal to one yard. For example, a pitch 1:12 means that per every twelve yards of building length the rise will be equal to one yard.
