Should siding be installed touching the roof? It really depends on the siding. Vinyl and aluminum siding are can be install against the roofing if so desired, because they are not damaged by moisture. Any type of wood siding or trim and fiber cement siding should have a two inch gap between its termination and the roofing. All to often this is not done because the roof flashing will be visible and it does not look “as pretty” as the siding. When there is no gap or only a small gap the bottom of the siding has to deal with constant moisture and it only takes time before the wood starts to rot or the fiber cement board crumbles and disintegrates. Life is so full of choices!
