Q: What is the proper spacing for roof trusses?

• <div><p>Building code allows 24-inch on-center spacing for roof trusses. However, you can install them on 12- or 16-inch centers to handle large loads or other exceptional circumstances. In cases such as covering a wide span or supporting <a href="https://www.angi.com/articles/budget-friendly-roofing-alternatives.htm">alternative roofing materials,</a> where a structural engineer needs to evaluate or create a design for your trusses, the plans will indicate the spacing. </p></div>

Q: What is a good slope for a shed roof?

• <div><p>The most common slope, or roof pitch, for a shed is 4:12 or four inches of height for every horizontal foot. For areas that experience heavy snow loads, a steeper roof of 6:12 or 9:12 is best. </p></div>

Q: Can you put new shingles over old shingles?

• <div><p>You can put new shingles over old shingles, but most municipalities only allow for two layers of shingles before you have to rip off the old roof and start fresh. In some areas, only a single layer of shingles is allowed due to the <a href="https://www.angi.com/articles/how-much-does-a-bundle-of-shingles-weigh.htm">weight a bundle of shingles</a> adds to your structure. In most cases, it&rsquo;s a good idea to remove your old shingles before you install new shingles, especially if you suspect that a roof leak may have compromised the decking underneath.</p></div>

Q: Can you add a roof over existing shake or shingles?

• <div><p>While you technically can add a roof over shakes or shingles, it&rsquo;s not a good idea. <a href="https://www.angi.com/articles/4-questions-ask-installing-roof-overlay.htm">Roofing over existing roofing</a> creates a moisture barrier underneath the new roof and since the trapped material is wood, you can expect a moisture problem. While you could get away with installing a new roof over asphalt or steel, wooden roofs should be removed, new underlayment installed, and the new roof installed over that. Also, the extra weight would add strain to your roof structure.</p></div>

Q: How do you prevent wind damage to your roof?

• <div><p>The best way to prevent wind damage to your roof, especially if you live in an area prone to hurricanes, tropical storms, or tornadoes, is to invest in a roofing product with high wind resistance. Look for the ASTM D3161 and ASTM D7158 ratings to see the specific wind speeds your roofing product can withstand. <a href="https://www.angi.com/articles/impact-resistant-roof.htm">Impact-resistant shingles</a> have the highest wind resistance ratings and will give you the best chance of avoiding wind damage.</p></div>

This was the only company out of the companies sent by Angi.com that responded. They were very timely in their response. Gave a lot of wise advise and were very knowledgeable. I purchased a different property out of the area, but I would highly recommend them.

"Best quote we got, out of multiple roofers. Marvin would show up when he said he would. He started working by 6:30 am. Finished the roof in one day, and it looks great. He is a very hard worker. And the quote was the price I paid. He didn't try to over charge."
