Everything for the outside of your home. S&H Building Materials is a family owned Long Island business located on Route 112 in Medford. We have been supplying roofing, siding, skylights, windows, doors, decking and railing to Long Island's residential builders, contractors and homeowners since 1965. We care about our Customers. We only sell building materials. We won't compete with our customers by offering to install materials like some of our competitors. This takes jobs away from our valued contractor customers who have kept S&H in business all these years.
