During our home inspections, we define the type of roofing material that is present on the home and also the condition. We typically will walk the roofs where possible, although many materials we do not walk to prevent damage.<\/p>\n<h2>But what about hail?<\/h2>\n<p>A common misconception about hail damage is that any hail will damage a roofing material and that the affected roof will fail shortly after the damage has taken place.<\/p>\n<p>This is not a correct understanding of hail damage. Smaller hail can fall onto your roof and have negligible effects on its performance. It takes larger hailstones, more than one-inch diameter typically, to cause impact damage on a roof.<\/p>\n<p>The largest<a href=\"https:\/\/www.gobuildpro.com\/roof-damaged-by-hail\/\"> issue with hail damage<\/a> is that it strips away the overall life expectancy of the product, particularly for asphalt shingles. Each sizeable impact of larger hail destroys the shingle and the roof will shed its roofing granules.<\/p>\n<p>You can imagine that your \u201ctwenty-five\u201d year shingle now only has half of that life left in it after significant hail damage.<\/p>\n<h2>What&#8217;s Underneath The Roof?<\/h2>\n<p><a href=\"https:\/\/www.nachi.org\/underlayment-types.htm\">An underlayment<\/a> is a product that is installed over the roof decking but underneath the selected roofing material. Older homes may feature tar paper or felt products while newer homes may have synthetic products applied.<\/p>\n<p>These underlayments are installed so that even in the event of a roofing material failure the wood decking underneath is protected from water penetration.<\/p>\n<p><a href=\"https:\/\/scotthomeinspection.com\/wp-content\/uploads\/2020\/11\/roof-underlayment.jpg\"><img decoding=\"async\" class=\"aligncenter wp-image-18389\" src=\"https:\/\/scotthomeinspection.com\/wp-content\/uploads\/2020\/11\/roof-underlayment-1024x649.jpg\" alt=\"synthetic underlayment\" width=\"450\" height=\"285\" srcset=\"https:\/\/scotthomeinspection.com\/wp-content\/uploads\/2020\/11\/roof-underlayment-200x127.jpg 200w, https:\/\/scotthomeinspection.com\/wp-content\/uploads\/2020\/11\/roof-underlayment-300x190.jpg 300w, https:\/\/scotthomeinspection.com\/wp-content\/uploads\/2020\/11\/roof-underlayment-320x202.jpg 320w, https:\/\/scotthomeinspection.com\/wp-content\/uploads\/2020\/11\/roof-underlayment-400x254.jpg 400w, https:\/\/scotthomeinspection.com\/wp-content\/uploads\/2020\/11\/roof-underlayment-600x380.jpg 600w, https:\/\/scotthomeinspection.com\/wp-content\/uploads\/2020\/11\/roof-underlayment-700x441.jpg 700w, https:\/\/scotthomeinspection.com\/wp-content\/uploads\/2020\/11\/roof-underlayment-768x487.jpg 768w, https:\/\/scotthomeinspection.com\/wp-content\/uploads\/2020\/11\/roof-underlayment-800x507.jpg 800w, https:\/\/scotthomeinspection.com\/wp-content\/uploads\/2020\/11\/roof-underlayment-1024x649.jpg 1024w, https:\/\/scotthomeinspection.com\/wp-content\/uploads\/2020\/11\/roof-underlayment-1200x761.jpg 1200w, https:\/\/scotthomeinspection.com\/wp-content\/uploads\/2020\/11\/roof-underlayment.jpg 1500w\" sizes=\"(max-width: 450px) 100vw, 450px\" \/><\/a><\/p>\n<p>One of the largest culprits of active roof leaks is found at roofing \u201cpenetration points\u201d where plumbing vents and mechanical systems penetrate through the roof deck and underlayment.<\/p>\n<p>These areas should be monitored as they pose the greatest risk of failure over time, although a professionally installed vent or \u201cboot\u201d should not leak.<\/p>\n<h2>My Roof Has Soft Spots!<\/h2>\n<p>Below the underlayment is the roof decking, also known as roof sheathing. This is typically sheet wood such as plywood or OSB particle board in newer homes. This provides a flat surface to lay the roofing material on.<\/p>\n<p>Not all building components are created equal. Some older homes that were built to be more economical may feature thinner roof sheathing or wider installation of rafters and trusses. This can give a roof deck a \u201csoft\u201d feeling when walking over the roof covering, where the roof bends slightly as you walk over it. This is not necessarily a roof defect and can simply be a consequence of the material choices made when the house was built.<\/p>\n<p>Also, older homes with plywood sheathing are more prone to soft spots in the sheathing. As the material ages, the sheets of wood adhered together start to separate, particularly with the high temperatures in the attic or if a past roof leak was present. Occasionally when replacing a roof, the sheathing will need to be replaced as well in softer spots. A roofer will make this determination.<\/p>\n<h2>What About The Attic?<\/h2>\n<p>It is quite common to find an attic space above the ceiling in a single-family home. These spaces are a great indicator of the overall condition of the house.<\/p>\n<p>An attic space can reveal the overall structure, insulation, and ventilation of the house which we will detail in other posts.
