When building a deck or exterior stairs i would lean towards redwood or a synthetic product such as Trex depending on the application.

IF $ feasable, tear off the existing layers of shingles, install a good THICK and SYNTHETIC underlayment (like Ice/Water barrier, not cheap synthetic) and not just 2 layers of black felt; insulation boards; then the metal roof. 

We contacted a contractor before about taking off EFIS synthetic siding and putting on hardi plank.

Zinnsser now makes a synthetic shellac called BIN2 which is not as nasty to use and far more affordable.Even after all of that, there have been a few studies which show that the nicotine and other toxins deposited on / absorbed into the walls and trim will eventually re-emerge on the surface.        

Moreover, if the house smells of too many synthetic fragrances, like candles, air fresheners, or sprays, it may be to cover up problematic odors.Check for leaks under the sinks, basement, windows, and other areas if you notice a moldy odor.

All quartz will stain and burn as it is a synthetic productThe RTA cabinets are more expensive then big box stores.
