Q: How many roof vents do I need for a 2,000-square-foot house?

• <div><p>The number of roof vents necessary for a 2,000-square-foot house depends on several factors. The calculation depends on the net free area within the attic and whether your municipality requires a 1/150 or a 1/300 ratio of venting square feet to attic square feet. If you install vents with a square-foot opening of one, you'll need either 14 or seven exhaust vents and an equal square-foot amount of intake vents. </p></div>

Q: What are the three types of rafters?

• <div><p>The principal, common, and auxiliary rafters are the most frequently used types of rafters. Principal rafters are large and typically appear toward the edges of the roof. Common rafters are smaller than principal rafters. Some people may use a mix of common and principal rafters. The auxiliary rafter is not common, but it provides extra reinforcement for a principal rafter on a large building.</p></div>

Q: What is the difference between roof sealant and roof coating?

• <div><p>The terms &ldquo;roof sealant&rdquo; and &ldquo;roof coating&rdquo; are used interchangeably to describe the rubber, silicone, polyurethane, or acrylic product applied to the roof&rsquo;s surface for waterproofing and UV protection. Products like roof caulk can also be called &ldquo;roof sealant,&rdquo; but the term is more commonly used for the protective coating.</p></div>

Q: Do you have to climb on the roof to install solar tubing?

• <div><p>Yes, you have to get on the roof to cut a hole for solar tubing. It's not possible to complete the job from inside your house by simply cutting through the ceiling. So if you want to go the DIY route, remember to use <a href="https://www.angi.com/articles/how-to-learn-ladder-safety.htm">safe ladder practices</a>. If you&rsquo;re not comfortable climbing on your roof to install solar tubes, hire a pro who has the tools and expertise to do the job safely.</p></div>

Q: Is it normal for a roofing estimate to change after the initial assessment?

• <div><p>It&rsquo;s possible for a roofing estimate to change after the initial assessment, but in most cases, it shouldn&rsquo;t. There&rsquo;s always the risk that something unexpected will happen that causes prices to go up, like discontinued materials or your roofer discovering previously hidden damage to your decking when ripping off the old roof. However, experienced roofers should account for these circumstances in their initial estimates. <a href="https://www.angi.com/articles/i-was-wondering-if-i-was-obligated-roofers-contract.htm">Roofing contracts are binding</a>, so always check your contract for language about how and why your numbers could change. </p></div>

"Fantastic contractor. Talked to the owner on Tuesday while they were doing a roof on house around corner from my house. He came by couple hours later to look at my house to give estimate. We agreed on price and next morning crew arrived and they stripped and reroofed my 2 story house in 2 days. Impressive how fast and efficient they were. Price was unbeatable. They finished and cleaned up like they were never there. Can't say enough positive about them. Don't even waste your time talking to other roofing contractors, this is the company you will want to use for sure."
