Q: What is the proper way to lay shingles?

• <div><p>The most important thing to remember when laying shingles is to work from the bottom of the slope to the top. This leaves you with a top overlap that directs runoff from one row to the next until it reaches the eave for disposal. You should also make sure you follow the manufacturer's instructions and the local building code for nailing patterns and frequency so all of your hard work stays put through varying weather conditions.</p></div>

Q: Do you need permission to raise your roof?

• <div><p>You&rsquo;re going to need a permit for nearly every roof-raising project. This is a very important step, as the work you&rsquo;re doing has serious safety considerations. Professionals are the ones to handle this type of work&mdash;including sourcing the permits&mdash;as they have the expertise required to perform the work safely. Insurance and warranty are usually voided if you do this work without a permit, and you may even be required to halt construction and tear it down as a <a href="https://www.angi.com/articles/common-problems-when-you-dont-pull-permit.htm">penalty for working without a building permit</a>. </p></div>

Q: What is a roof pitch multiplier?

• <div><p>A roof pitch multiplier is an accurate way to <a href="https://www.angi.com/articles/how-to-calculate-roof-square-footage.htm">calculate roof square footage</a>, and it&rsquo;s handy for purchasing the correct amount of materials. To determine your roof pitch multiplier, you'll need to calculate the roof slope, square it, and add it to 144. Next, find the square root of the total and divide it by 12. The answer is your roof pitch multiplier. Once you know the roof pitch multiplier, multiply it by the total square feet of your building to determine the total roof surface area. </p></div>

Q: Do algae-resistant shingles prevent moss?

• <div><p>Yes, algae-resistant shingles will prevent algae and moss growth, providing double protection for your roof and <a href="https://www.angi.com/articles/what-is-roof-flashing.htm">roof flashing</a>. The copper-infused granules on algae-resistant shingles release copper ions that inhibit plant growth in general, so moss will have a harder time growing on your roof, too. Keep in mind that copper ions flowing off your roof during rainfall can also inhibit plant growth below, so your gardens and grass may be affected.</p></div>

Q: How long does single-ply roofing last?

• <div><p>Single-ply roofing lasts for between 15 and 30 years, depending on the type you install and the climate in your area. TPO roofing has the shortest lifespan of 15 to 30 years, followed by PVC, which lasts for 20 to 30 years. EPDM roofing is the longest-lasting single-ply roofing option, with a lifespan of 30 to 40 years. Keep in mind that hail, strong winds, blown debris, and foot traffic can all reduce how long your flat roof lasts.</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."
