Q: What causes roof sheathing to buckle?

• <div><p>Roof sheathing can buckle from moisture damage, too much weight from roofing materials, or too much space in between rafters without thicker sheathing to compensate for the added distance. Bucking roof sheathing is a serious problem that can lead to a collapsed roof, so have a qualified <a href="https://www.angi.com/nearme/roofing/">roofer near you</a> come to identify the problem as soon as possible. </p></div>

Q: Can you walk on a clay tile roof?

• <div><p>It&rsquo;s possible to walk on a clay tile roof, but you run the risk of breaking or cracking the tiles if you&rsquo;re not careful, so it&rsquo;s best not to walk on it if you can avoid it. If you or a contractor needs roof access, be sure to distribute your weight evenly and step on the portions of tile that are also supported underneath, which depends on your tile design. Walking on any roofing material is inherently dangerous, so wear rubber-soled shoes and use safety equipment if you need to access your roof.</p></div>

Q: How do I know if my roof vent boot is leaking?

• <div><p>The easiest way to tell if your roof vent boot is leaking is to look in your attic for signs of water damage. You might see visible moisture, water spots, or mold on the roof decking around the roof vent or damaged or soggy insulation below it. If you don&rsquo;t have access to your attic or aren&rsquo;t sure if the vent boot is the issue, hire a professional to come inspect your roof and figure out the underlying issue.</p></div>

Q: Why is it necessary to have your chimney crown inspected?

• <div><p>Most chimney crowns cannot be seen from the street or yard. As a result, most homeowners are completely unaware that their damaged or deteriorating chimney crowns need repairs or replacements. <a href="https://www.angi.com/articles/what-expect-chimney-inspection.htm">Chimney inspections</a> offered by contractors can verify any damage. </p></div>
