They did a really, really good job. It's a steel roof. They were not the cheapest of the quotes that we got but they were really really good. We got them through recommendation from friends who had used them. We didn't see any cleanup. There was no rubbish anywhere in our garden. We don't remember but about a week. It included the garage.

Added a third layer roof that lasted until I received a form letter form the city in 2012 informing me that I had to do full tear down and new roof in order to be code.  
Was unable to find listing for Davis Roofing at this time, so I ended up using a different company and getting a roof that leaked first time it rained that I have since had repaired by another roofer.
If I had found listing for Davis Roofing in 2012, I would have asked them to do the new roof as I was very pleased with their work in 1995 and recommended them to neighbors back then.

Kim made an excellent presentation with a comprehensive portfolio showing photos of the process and how his workers accomplished each project. I saw nice, clean looking employees wearing clean uniform shirts with the company logo on it. Kim explained how the process will go...  He assured me that the workers will be employees of his company... NOT day laborers, there will be a foreman on the job, they will clean up after themselves each day and he will check in on the job each day as well. What we got was something else entirely.
The workers were the scuzziest looking characters we had ever seen. Needless to say, there was no clean shirt with the company logo on it. Now I realize that roofing is not a tidy job...  workers get dirty... filthy even, but these men showed up looking filthy. There were a few areas in the overhang, over the windows that needed replacement boards where there was rotted wood. Whenever I would check the area after it was completed, I found the wood they used to replace the rotted wood looked like it had been used, charred and pretty much as rotten as the wood they were replacing. We expected new, clean wood to be used. I saw this in several places. When I tried to explain to the foreman that this was not acceptable, he had difficulty understanding me. So we had to call Kim to come to the house and see for himself and act as interpreter for us. The cruddy wood was replaced with new wood. There were a few occasions when we had to ask Kim to come to the house to correct a situation. Each time, it was getting longer for him to respond; clearly giving the impression that he was avoiding us. What concerned us was if we found problems with their work that we could see... what was going on overhead on the rest of the roof that we couldn't see? Who knows the condition the plywood that they used. The workmanship that we could actually see did not inspire confidence.
As for clean-up each day... that was a joke. Every night my husband would look over the work that had been done... picking up nails, wood and shingle scraps as well as garbage tossed in the bushes. They would leave their hot-plate (for preparing lunch) on top of a table in the middle of the patio. Every day it was something else, even after voicing our concern.
Needless to say, they completed the job. The very next day there was a very light rain. The rain water leaked into the dining room exactly where it did before. Kim brought his foreman out and he repaired it immediately and the leak stopped.
What I found interesting was... that was the only place the roof was leaking. In my first discussion with Kim, I told him that was the only leak. Kim said that it impossible to tell where the source of the water is coming from since water travels...So, we re-roofed the entire house. So how is it that they knew exactly where to fix the leak THIS time?
We don't think Kim was forthcoming with what we were to expect... with their workers and their quality. I am also suspicious that these were day laborers doing the work. We would never refer this company to anyone. Yeah... we got a new roof... but it sure wasn't worth the aggravation.
We are just posting this review now because we just joined Angie's List. We are about to do some more renovations on our home and we do not want to have the same experience. This site is such a terrific source of information. Thank you, thank you Angie!!!

JNDavis roofing repeatedly ignored my service call one year after their work finished.  All that I wanted was for them to check and fix some roof tiles at my expense.  This company definitely is not here to support their customers.  Once they make the money from the initial project, they will do anything to not have to hear from you again.  I'm p***** off about how unprofessional they are and will make sure people are aware of their bad behavior.

The process went very well.  Kim gave us 3 quotes for 3 different products.  The company was flexible with our schedule and finished in the timeframe stated.

Kim Smith, the owner, came out to give the estimate and was very thorough in his explanation of what we had and what he could do. They tore off our leaky, nasty roof and replaced it with a cool roof (the white membrane reflects heat) that is heat welded so it won't leak. He said it would keep our house noticeably cooler in the summer and he wasn't kidding. A few weeks later was a heat wave and we didn't need to turn on our air conditioning even though it was in the 90s. We did have a leak during the next rain, and Kim came out to check on it. Even though he said it was not due to their work (of course he would say that), he spent two hours (no charge!) on our roof repairing it himself and it has been fine ever since. They did a great job, fast and clean, and for the same amount of money as our other estimates (for non-cool roofs).

A new coat of La Polla was applied to the roof. New metal coping of parapet was was also installed. Overall I'm very happy with the whole process.

The estimate cost was reasonable, although not the lowest. The work description provided in the estimate was excellent and is the main reason we selected the company. The work was done promptly and on the date we agreed to. Couple of small glitches: the workers broke one tile on the roof parapet and they did not have a replacement. Fortunately I have some old tile pieces they could used to cover temporarily. Eventually, I will have to go look for a permanent replacement. In addition, they do not have any paint for the flashing they installed around the chimney. Again, we did plan to repaint the outside of the house. So that is OK. Otherwise, we will be left with an unpainted flashing piece subjected to weathering. The repairs looked good and have not leak yet!

I called and left a message. They called back and set up an appointment. The roofer came but needed a longer ladder. He came back the next day and completed the work.

The job turned out wonderfully. He was very honest and even though I insisted that I needed a new roof he told me I didn't. He save me thousands of dollars and did the work that needed to be done. He could have went ahead and put on a new roof, but he's a very honest and nice man. They were able to finish everything within just one day and I thought the price was more than fair. It has withstood all the rain we had so far. I would rate him and his workers and "A" across the board.

no problems, did the work professionally. i needed misc. roof repairs, including replacement of some shingles. the foreman was very knowledgeable and his crew was excellent. later, i obtained a bid for replacement of my roof, and while not the lowest bid, i feel that this outfit would do an excellent job and stand behind their work. what more could you ask for?
