Why do copper roofs turn green?

• <div><p>The green coloration that develops on copper roofs is called a “patina,” and it’s a result of mild oxidation on the surface. The oxidation process is not harmful to your roof. In fact, the surface corrosion acts as a protective layer and won’t spread to the core of your copper roof materials. The discoloration will progress much more quickly in damp or humid climates than it will in dry climates. If you don’t like the green color, you can seal your roof to preserve the shiny, rose-gold look.</p></div>

Q: Will my homeowners insurance cover repairs resulting from storm damage?

• <div><p>Yes, most standard policies include storm damage repairs. Your policy may cover some or all of the repairs. The first thing to do after a storm is contact your home insurance agent. If you get any work done before the adjuster arrives, such as covering holes in your roof or windows, keep those receipts for reimbursement.</p></div>

Q: What are the common applications of sheet metal repair?

• <div><p>Sheet metal repair is commonly applied in automotive, construction, HVAC systems, and roofing repairs to maintain durability and aesthetic appearance.</p></div>

Q: Can I repair a metal roof myself?

• <div><p>While DIY patching is possible, professional services guarantee reliability in workmanship and adherence to safety standards.</p></div>

Q: Are copper roof strips more effective than zinc roof strips?

• <div><p>Copper roof strips offer better coverage and more damage protection than zinc roof strips. Although both deter moss and algae growth, copper also offers UV protection. Zinc strips require more strips than copper to cover the roof&rsquo;s surface area, which means more holes in your roof. Copper strips are also more flexible and last longer than zinc strips.</p></div>

We first went to Purrfect Auto on Eastern in Henderson and they quoted $700 to repair. I then went on Angieslist to find a shop. Found Sun auto then went there. They quoted $200 and repaired the car. Works great and saved $500. I think we found our auto center for future repairs.

Service went very well. They showed up on time, brought in their equipment and started with the job. He noticed some traces of past fired in the chimney but said they weren't bad and there was no need for a deeper cleaning. He got the job done and had me ready to burn some wood!
