Q: Can moss damage my roof?

• <div><p>Yes, moss can be dangerous for your roof if left in place to grow without treatment. The moss soaks up and holds moisture. Having a constantly damp roof could lead to problems with rot for the parts of the roof that consist of wood. Additionally, a patch of thick moss may draw insects and birds, which could damage the roof. Thick moss could block the roof&rsquo;s drainage system. Water then may back up after a rainstorm and cause further damage that could eventually lead to roof repair expenses or the <a href="https://www.angi.com/articles/how-much-does-roof-replacement-cost.htm">cost of roof replacement</a>.</p></div>

Q: Where is the chimney crown located?

• <div><p>Chimney crowns are located above the final brick layer at the top of a chimney. It&rsquo;s important to get regular chimney maintenance and inspection, because it is near impossible to spot chimney crown damage without getting on your roof. </p></div>

Q: How much does a new roof or roof replacement cost?

• <div><p>The cost to replace a roof typically ranges from $8,700 to $22,000, with a national average of around $9,200. The total cost depends on the size of your roof and whether you need a full replacement or can simply place new shingles over the old ones. A full replacement, which is necessary if the roof is several decades old or has multiple layers, is more expensive. This process involves tearing off the old roofing materials, inspecting and repairing the underlying structure, and then installing the new roof.</p></div>

Q: Are chimney crowns the same thing as a chimney caps?

• <div><p>No, a chimney crown is not the same as a chimney cap. A chimney crown is a flat cement area on top of a masonry chimney. It starts where the masonry part of the chimney ends at the very top and domes upward toward the flue opening. A chimney cap sits on top of the crown over the flue. It is usually made of metal and allows smoke to escape without letting in rainwater.</p></div>

Q: Does a metal roof over shingles require an underlayment?

• <div><p>Underlayment is used between existing shingles and a new metal roof to prevent friction and wear from the shingle granules on the underside of the metal. The underlayment also helps prevent water intrusion and allows expansion and contraction without wearing away at the roofing material.</p></div>
