When it shrinks, it can pull away from seams and fasteners, creating exposed areas where water can infiltrate. This can lead to:<span class=\"prose block px-4 mb-4 wp-core-block-list\">\n<ul class=\"wp-block-list\">\n<li>Leaks in your attic or ceiling<\/li>\n\n\n\n<li>Mold and mildew development<\/li>\n\n\n\n<li>Rotted sheathing or framing<\/li>\n<\/ul>\n<\/span><\/li>\n\n\n\n<li><strong>Compromised Wind Uplift Resistance<\/strong><br>Many modern underlayments contribute to the roof system\u2019s ability to withstand uplift forces from high winds. If the underlayment shrinks and loses adhesion or fastener hold, it weakens the entire system\u2019s structural integrity &#8211; especially critical in hurricane- or storm-prone regions.<\/li>\n\n\n\n<li><strong>Delamination and Wrinkling Beneath Shingles<\/strong><br>Shrinkage can cause the underlayment to wrinkle or buckle. This creates an uneven surface that can telegraph through asphalt shingles, causing them to lift or wear prematurely. Worse, wrinkled underlayment may prevent shingles from sealing properly, leaving them vulnerable to blow-off.<\/li>\n\n\n\n<li><strong>Shortened Roof Life<\/strong><br>All of the above add up to a single painful truth: if your underlayment fails, your roof will likely fail long before its intended service life. Even if you invest in premium shingles or tiles, a shrinking underlayment undermines that investment from day one.<\/li>\n<\/ol>\n<\/span>\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n<span class=\"prose block px-4 mb-4 wp-core-block-heading\">\n<h3 class=\"wp-block-heading\" id=\"h-how-to-prevent-underlayment-shrinkage\"><strong>How to Prevent Underlayment Shrinkage<\/strong><\/h3>\n<\/span>\n\n<span class=\"prose block px-4 mb-4 wp-core-block-paragraph\">\n<p class=\"wp-block-paragraph\">Fortunately, underlayment shrinkage is preventable &#8211; but only with the right practices and materials:<\/p>\n<\/span>\n\n\n<figure class=\"wp-block-image alignright size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"350\" height=\"256\" src=\"https:\/\/itape-qa-wp.itape.com\/ecpinfo\/wp-content\/uploads\/sites\/16\/blog\/ns-pro-img.jpg?w=350\" alt=\"NovaSeal Pro Product - Blog\" class=\"wp-image-2485\" srcset=\"https:\/\/itape-qa-wp.itape.com\/ecpinfo\/wp-content\/uploads\/sites\/16\/blog\/ns-pro-img.jpg 350w, https:\/\/itape-qa-wp.itape.com\/ecpinfo\/wp-content\/uploads\/sites\/16\/blog\/ns-pro-img.jpg?resize=300,219 300w\" sizes=\"auto, (max-width: 350px) 100vw, 350px\" \/><\/figure>\n\n\n<span class=\"prose block px-4 mb-4 wp-core-block-list\">\n<ul class=\"wp-block-list\">\n<li><strong>Use high-quality, low-shrink underlayments<\/strong><\/li>\n<\/ul>\n<\/span>\n\n<span class=\"prose block px-4 mb-4 wp-core-block-paragraph\">\n<p class=\"wp-block-paragraph\">Not all underlayments are created equal.\u00a0<a href=\"https:\/\/itape-qa-wp.itape.com\/ecpinfo\/product\/novaseal-pro\/\"><strong>NovaSeal PRO<\/strong><\/a>\u00a0from IPG is engineered specifically to combat shrinkage, outperforming traditional felt and many synthetics in dimensional stability and durability.
