Q: Where do most roof leaks occur?

• <div><p>Most roof leaks occur where shingles meet or where there are sealants or seams in the materials. This is common around skylights and at any point there is a break in the roof such as corners and edges. Roofing materials are incredibly strong and resistant when overlapping, but any change in that can cause gaps where water can enter.</p></div>

Q: What’s the difference between a mansard roof and a gambrel roof?

• <div><p>A gambrel roof and a mansard roof are similar in that they are both hipped roofs, meaning they have double slopes&mdash;one steep and one more gradual above the steep slope. The difference is that a gambrel roof has a double slope on only two sides of the structure, whereas a mansard roof has a double slope on all four sides.</p></div>

Q: How long do torch down roofs last?

• <div><p>The lifespan of a torch down roof depends on the number of layers installed. A single-ply system typically lasts between 10 and 15 years, while a multi-layer system with two or three layers can last from 15 to 25 years. Although a multi-layer option may be more expensive upfront, it provides a longer service life. Warranties often reflect this, with about 12 years for a one-ply system and 15 years for a two-ply system. For context, this lifespan is shorter than other common roofing materials like wood or asphalt shingles, which typically last 20 to 30 years, with high-quality versions lasting up to 50 years.</p></div>

Q: How do I repair flapping shingles?

• <div><p>Flapping shingles, or shingles that are lifting or curling away from your roof, can be glued back into place using roofing cement or sealant. Apply the glue underneath the shingle, then press it down firmly. You can leave a brick on top of the shingle to hold it in place overnight while the sealant dries.</p></div>

Q: What are some disadvantages of a flat roof?

• <div><p>There are several<a href="https://www.angi.com/articles/pros-and-cons-of-flat-roofs.htm"> pros and cons of flat roofs</a>. One disadvantage of flat roofs is that you lose potential attic space because it's flat. Flat roofs tend to pool water and because they lack an angle, any leak in the roof&mdash;usually due to a bad seal&mdash;has the potential to let in a lot of water. They don&rsquo;t work well in climates with snow. Flat roofs are also structurally weaker than sloped roofs.</p></div>
