"I am sure that all positive reviews for this company are fake. Nothing that was promised to me was delivered. My siding project is still ongoing for over 1 month. Was told that it would be done in week. Had one rain day. They have system like this: 1) sales person who never installed anything he will promise you things that obviously are not true, 2) crew that is subcontracted but not Gunner, mine was driving for over 2 hours away, 3) person who oversees the project but has little control over anything, no supply, doesn't know the crew, crew does not listen to him, main office does not listen to him, 4) main office does not reply to you. They just tell me to talk to project manager who has no control. So you understand that if there are any issue you are on your own. Quality or work is not good. Many times I had to point to the crew what's wrong, planks are broken yet they were still installing it, caulking is done they way that I can do it better, they cut wires to awning etc"

"TLDR: Have the quality of the work stated in the contract, not just that the work will be done. This was by far the worst contractor I have ever hired. I hired them to hang drywall in 2 bedrooms, box in a pole in my basement, box in a duct, finish mud on some drywall that I hung myself, and paint my kitchen/living room. They continually messed up and I had to personally show/tell them how to do their job. The pole they boxed in, in my basement, was over an inch and a half out of level. To the naked eye, it looked like it was leaning. Same thing with the duct they boxed in. When confronted, they blamed my children for kicking the pole out of level, when it was actually screwed into my concrete foundation. They claimed to have built the duct box out of square on purpose. They flat out missed spots in my living room when they were painting because they were careless. You can see individual roller marks on the walls. Drip marks abound. My 10 year old could have done a better job painting with a roller than these guys did. There is paint all over my vaulted hardwood ceilings that they didn't bother to clean. There is paint on my kitchen table. There is paint on almost every door and window in every room they painted. One evening they left and I had to clean up their paint pans and rollers. The drywall work is possibly the worst I have ever seen. I can see most of the drywall seams because the mud is feathered so poorly. They missed every outlet box they cut out in the two bedrooms. Then they just fished the wires through the hole and screwed the outlets into the drywall. They continually did not bring the tools and supplies they needed to do the job that day. Usually blaming my children for taking supplies they claimed to have left the day before when I never even saw them. They went so far as to claim my dog ate an entire 18 lb bag of quick set drywall mud. They often borrowed my tools to get the job done. They left my $600 flexvolt miter saw out on the deck in the rain and below freezing temperatures with two 12 amp hour batteries in it. They would have walked off with my impact driver if i hadn't caught them. They did get away with my chalk line, two screwdrivers, and a paint pan. For real.... They were hired to paint and had to borrow my paint pan. I cant even make this stuff up. Rarely showing up before noon and often staying past eight or nine in the evening. They didn't leave my house until ten thirty once. Sheena left her cigarettes on my 10 year old daughter's dresser. They left an open razor knife on my other daughter's desk (my children are all 10 years old and younger). Their communication was absolutely abhorrent. I never knew if they were going to show up. Once, Sheena texted me that they were on their way (45 minutes, an hour max of travel) and showed up 3 hours later. Some days they just plain didn't bother to show up at all and didn't tell me at all that they weren't coming. It seriously takes 90 seconds to send a quick text saying "hey there was an ice storm and we can't make it today because of the weather." The entire job was supposed to take a week, but to be on the safe side they said 2 weeks in the contract. They finished on day 19. Nearly 3 weeks to finish a week's worth of work. These guys are absolute clowns. If I could rate 0 stars, I would."

"Nothing but problems. Sheet rock in kitchen came down repeatedly due to leak. Then in the living room. Next was a leak around the chimney. It was like pulling teeth to get a response from Garvin and each repair had to be done more than once. Now there is mold all over the kitchen due to a fourth area that is leaking due to incorrect installation. He is now saying the subcontractor he hired should be responsible. The owner ignores complaints. He did send some one to put a tarp on the roof so the structural damage and mold caused by the leaking roof can be repaired. He does not respond to communication by phone email or text. I don't know about the price - would not hire again if it was free."

Roofing questions, answered by experts

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.

It’s not customary or expected that you tip your roofer or their crew. It’s entirely up to you if you’d like to give them a little extra money for their work. One way you can show appreciation is by picking up coffee or breakfast for the crew. If you feel like they’re doing an exceptional job, tipping can be a nice gesture but don’t feel like you have to.

Depending on the type of damage your roof shingles have, you may be able to simply repair them without having to replace them. However, if there are more than a few to repair, replacement is likely the easier option. You may only need to replace a few of them. Repair shingles by applying roofing sealant directly under the shingle's damage and then directly over it. 

A chimney liner is typically easier to install by pushing it down through the chimney with the help of a rope. Depending on your fireplace and the type of liner, installing it by pushing it up through the chimney could work, but operating from the top down is usually the best option.

Though roof coatings can last up to two decades, it’s a good idea to recoat your roof every four to six years. This is especially important if you have a built-up roof, which is vulnerable to moisture issues. Inspect your built-up roofs annually to make sure they don’t need a new coat.
