Roofing Quotes

We have already obtained one quote for ceramic-shingle roofing (which looks a lot like slate). Today I have typed up two more letters to get a further quote for ceramic shingles from a different supplier, plus a quote for genuine slate (as a comparison). Apparently cheap slate isn't all that good, and is prone to cracking (and can't be walked on), so we are leaning towards the ceramic shingles. Fortunately, not all the roof needs to be clad with shingles, as we have a central valley in the roof design (to reduce the height of the roof). This valley is unseen and can be clad with corrugated colorbond steel.
