When it begins to flex or compress under pressure, the problem is usually <strong>below the finished flooring<\/strong>, not on top of it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Most residential floors are built with:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Finished flooring (hardwood, laminate, tile, vinyl, or carpet)<\/li>\n\n\n\n<li>An underlayment<\/li>\n\n\n\n<li>A <strong><a href=\"https:\/\/www.flooringamerica.com\/blog\/what-is-a-subfloor\" target=\"_blank\" rel=\"noopener\">subfloor<\/a><\/strong>, typically plywood or OSB (oriented strand board)<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">When moisture penetrates the subfloor, it absorbs water like a sponge.

These leaks often go unnoticed because the water spreads <strong>under flooring<\/strong>, not across it.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"appliance-leaks\">Appliance Leaks<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Dishwashers, washing machines, water heaters, and refrigerators with ice makers frequently develop small leaks. A few drops per day may not seem serious, but over time, they can completely saturate the subfloor.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"roof-and-window-leaks\">Roof and Window Leaks<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Water doesn\u2019t always drip straight down.
