Wonderlin Roofing Systems Inc.

About us

Grover Wonderlin has been the driving force behind his family run business since 1992. He has specialized in residential and commercial re-roofing. Grover’s Son in law Ryan Piekarczyk has been part of the backbone of the company. He started with Wonderlin Roofing in 2003 as a job foreman and is now co-owner with Grover. Believing that customers deserve the best quality work and knowledgeable service, Grover and Ryan personally oversee each and every job, from estimating to application of the new roof. Although this limits the number of roofs they can complete at one time, they prefer to give their customers this personal service: “Quality instead of quantity”. The customer ends up with a better roof and far less headaches. In fact, Grover and Ryan give their cell phone numbers to every customer, so that they can be reached at any time, between 9am-5pm, to handle any concerns or questions during the job.

They were the only company (out of 4 contacted) that provided a prompt and detailed estimate. They recommended installation of gutter screens due to abundant leaf drop from homeowner association trees, which turned out to be a good decision. They kept me informed of the start date, and any changes due to weather conditions. Roof tear off was quick (1/2 day). Lots of people worked on roof installation (including the owner and co-owner), which took one day. This included replacement of a little roof decking around the chimney, which had become damaged over time. One more day needed for removal and installation of new gutters and gutter screens. They made sure everything was picked up and cleaned after each phase (tear off, roof installation, gutters). Office staff was top notch and answered all my questions. They also prepared for the required city inspection/permit sign-off. They were recommended to me by a friend who had 2 roofs done by Wonderlin (her's and her mother's). Would gladly use them again.

Grover and his crew were respectful, on time and cleaned up everything beyond expectations.  Very professional.  What I liked most was that Grover (owner of Wonderlin Roofing) was the only one of the three companies (all highly rated) that gave estimates who acknowledged from the outset the necessary extra work of cutting back and repainting the rafter tails--a lot of extra work when you recognize that 1/3 of the roof  is perched over a steep canyon...long ladders were required.

this provider is too busy to take any time to do estimates - I suggest not wasting you time unless you know them personally which I do not.
rather than call to cancel I got an email that I almost missed - would have p***** me off even more if I waited for the estimator and then learned they refused to come out.
again - not worth wasting your time - go elsewhere

I received 5 quotes and Wonderlin provided the most detailed explanation and was able to identify the problem and provided a full contract. Work was thorough and we are very satisfied with the results. The only difficulty was communication and confirmation of the date for the job, but since it was a small job I'm glad they were willing to take it on.

They are a family owned business. They were very competent, professional and quick. They were very pleasant to deal with and everything went great. They left the place neat and clean. There was no damage to plants surrounding the house. They were very thoughtful about our comfort and convenience. They completed the job in (2) days.

I got only two estimates for roof maintenance work. Wonderlin's estimate of work seemed to be more inline with the work that had to be done. Their estimate was also more comprehensive in the work that needed to be done and it was lower priced than the other company. So basically I was getting more bang for the buck.
The estimator arrived on time.
The work crew arrived a little late of the estimated start time but was able to finish the job in less than three hours. In addition to the work they said they would do, they also cleaned out my gutters. The cleanup of the work area was spic and span.
I'm quite happy with Wondelin and I will use them again when I need to replace the roof - 10 years.

Everything went well. They arrived on time each day, and the work was completed in 2.5 days. The owner (Grover Wonderlin) was on site some of the time and even performed some of the work himself. I would recommend this company.

Initially, we weren't happy with the way the terra cotta looked -(we let them know before they were finished tiling it that we didn't like the way it was being done).

So....., they removed all of the tiles and brought in another craftsman to redo it....Beautiful! Wow!

These people were such a pleasure to deal with. A VERY positive experience!

They're a fine company. I've been dealing with them for close to 20 years now. I started out with them when they first opened. It's a private business and he did most of the work himself. All the work they have done for me has been great. The price is not cheap but it's well worth the money.

We are in a different state than the house that needed the roof and had to have all our questions and concerns handled via phone or email. They professionally and cheerfully handled all our needs, even taking pictures of the roof and gutters to help us to see areas in question. It was a pleasure to work with them. Both their office staff and roofing experts communicated with us constantly every step of the way. We got 4 bids from other companies. Wonderlin's bid was lowest of the mid-range and we felt we got better service by using this company. Combined expense for both gutters and roof replacement was $15,000.

They did a lot of work for e and they were wonderful. I would highly recommend them. One of the owners actually does the work and they oversee everything. They've had their employees for a long time. They cleaned up every day at the end of the day. They made sure that everything was done in a timely manner. They were wonderful to work with. I didn't have any problems with me. Their pricing was fair. They were very careful with everything they did. They always responded right away. They actually answer their cellphones.

I would recommend Wonderlin to anyone. Grover the owner came out and worked out the numbers right there on the spot and even helped me out some with the price. The only thing I wasn't informed about is that the trailer they had would be blocking my garage all weekend. This was not a big deal though. Wasn't sure what time they were going to start the first day.

GREAT!!! i was so fortunate to have contracted with Wonderlin Roofing - professional, prompt, complete, clean, kept in good contact with me every step of the project. they remedied the problems that initially existed, corrected the damage caused by the first company, completed all needed repairs and installed my roof, skylight and two attic fans - in addition to prepping my roof boarders for new gutters. i will be having them do more work that needs to be done before i can have the gutters installed. i would highly recommend them and look forward to the next job.

Overall, I was super pleased at the beginning to the end result. From my initial contact with owner, Grover Wonderlin, who was knowledgeable , informative and with an engaging personality, made the whole process pleasant. I was comfortable with his presentation and especially obtaining a start date so quickly. I was home for most of the roofing process and although the roof activity was often loud, it was not intolerable. I absolutely love my new roof, particularly the color and style of my new shingles. Thank You entire Wonderlin Roofing Crew!

I used them before and they were excellent in repairing the window as well. It was a great experience. They were professional. They cleaned up and didn't charge me to fix the window. I would use them again.

He told us how to fix some minor things and didn't charge us for that advice. I was able to fix it myself.

He did a pretty good job. He wasn't the easiest guy to get ahold of. I was painting the house at the same time and I thought I was going to do this wonderful sync up where I could get those guys to work together. When one guy pulled the gutters off the other guy could paint the house but that was a fantasy land. They were both hard to get ahold of, but I was satisifed with the work he did.

Great!! They did a great job and cleaned up pretty well (for the most part it was had to tell they had even been there). Very nice and prompt. They even let us decide on a gutter color after they had delivered the shingles, as we wanted to get a better idea of the colors we were dealing with.
