PROVIDENCE, Rhode Island [At the JLC Live Residential Construction Show] – What will tariffs mean for the residential construction industry? It depends. …Since all the other asphalt shingle manufacturers get their oil from Canada, the most likely scenario is that all the companies raise their prices, even if the shingles are produced in the US. Canadian shingle manufacturers will feel the most pain when exporting to the American market because of the cost of tariffs on their finished product, Hartnett said. Canadian wood: Manufacturers and sellers of anything wood related are going to feel the pinch. Wood is one of the most-used materials in residential construction (aluminum and steel are more prevalent in commercial and large residential buildings), and much of it comes from Canada. New Hampshire wood supplier Weyerhaeuser’s John Evans said much of their raw materials come from Canada, which will be hit by tariffs.
