From the moment we were contacted by Jake Fairbanks, everything has been just outstanding. Jake and his crew have been very polite and working around me and my wife’s work schedule. Even if there were an issue we always got an email or phone call to let us know of any issues. The work is top notch and everything went off without a hitch. They even told me about a hole in my roof and Jake and a coworker went on our roof and put a tarp over the hole because we were expecting snow, and all this was before we decided to use his company. That to me is outstanding. I would recommend Custom Onside to anyone asking about a roofing company. Friendly, neat, excellent communication skills and very efficient. Oh yes, the follow up is on point, you still here from them weeks after your roof is done. Can't go wrong with Custom Onside roofing.

  • Jake came to our door with recommendations from other neighbors in our neighborhood who had their roofs done from the July 4th storm. He gave us a bid and helped us through the process with the insurance and HOA. The roof was finished in a day and looks great! Easy process!

  • Awesome company that do a quality job!

    Kofi Fefe
  • Phil and Custom Onside were incredible to work with. My roof replacement was easy, they helped me with my claim and put a great roof on fast. I used them at my new house too and they did an excellent job. I got a much higher quality roof for a great price and they got it done FAST! Phil went the extra mile and made sure everything was cleaned up and even found some trash the previous tenant had left and cleaned it up for me. They even helped me move furniture into my new house in their downtime! I highly recommend working with Custom Onside, they go the extra mile in every way!

  • Jake was very helpful and was able to answer all the questions that I had. As the project went on he was there to take care of what ever came up. The roof looks great and I would recommend them to anyone else that needs a new roof.

    Dewayne Edwards
  • Custom Onside were very friendly, gave us a very competitive quote, and completed the job in just over one day. The owners are great, include post install inspection and minor repairs to the siding of the house at no extra charge. Highly recommended!

    Con Tsang
  • We had a positive experience working with Custom Onside. Our entire roof was replaced due to age and hail damage. Custom Onside did a great job of helping us through the insurance claim process, choosing the shingles, and getting the mid and final inspections. We really had to do very little, and the communication the company provided was appreciated.

    Sarah Abernathey
  • Custom Onside repaired our roof a few weeks ago. We had damage from ice damming a few winters back and Phil and his team helped us out. They were easy to work with, reliable and professional - all at a fair price. I'd highly recommend them for roofing, windows, gutters or siding needs!

    Bridget Kelley
  • I would like to share my positive experience with Custom Onside with my recent roof replacement. They were very professional, they helped me through the insurance process & roof selection. Basically made it very simple. Their crew did a great job in the install and we are very happy with the whole experience. If you are looking for a contractor to replace a roof or gutters, I would highly recommend them.

  • Met with Phil and Jake. They are great guys that are professional, kind, and care about their clients. Keep up the good work!

    Erica Petersen
  • Cory and the team are doing extremely professional and prompt! His follow through and communication is 2nd to none. I really appreciated the level of communication and education that he provided for me. I will be using Cory and his team from here on out for all of our roofing needs! Give them a call if you want the best service in the industry!

    Tyler Enlow-Gance
  • Jake and everyone we dealt with were amazing. Everyone was straight forward and honest with pricing and the process and with work being done. All work was completed in a timely and professional manner. Highly recommended for any work you need done.

    Jay Wittenburg
  • Jake and his team worked diligently to navigate our HOA restrictions and once approved did an amazing job painting our home. They were careful to native around our large trees and spared no efforts in completing the project to our satisfaction. I highly recommend their services and will continue to work with them for our future home needs!

    Genaro Laynes
  • We used Phil and his team to replace our roof before installing solar. Their pricing is competitive but more importantly they answered all the questions we had and were always prompt with communication. They completed the job quickly once the weather cooperated. Definitely recommend them.

    Dawn Chau
  • We have a home with a roof that just wore out … didn’t have hail damage. Waiting as long as we could, when we had Custom Onside come out to evaluate our house we were pleased to receive clear communication and very direct feedback about the state of the roof. As we were choosing new shingles, Phil Mihlstin provided us options within our budget that would also resist hail damage longer. Even with a few unique things to our situation, the team that replaced the roof were efficient and did exactly what was expected.

    Jessica Dewell
  • We initially wanted to get our roof replaced but since we had solar panels on our roof, it was going to cost us an arm and a leg to get the solar panels removed and reinstalled. So we decided not to get our roof replaced. We were in the process of having some guys come out and clean our roof due to pigeon nests and poop. Jake stopped by and handed my sister his card. My sister told Jake about our situation. How we didn’t want to pay to get out solar panels removed and reinstalled. Jake told my sister that if we have hail damage to the roof then insurance should cover the costs of the solar panels. My sister gave me his card and I called and spoke to Jake and that’s when we got the ball rolling. Jake was very knowledgeable and did a great job communicating with me through out the whole process and kept me updated. The process took awhile waiting on the mortgage and solar company to come out but everything went flawlessly and quickly once we had everything we needed. I would definitely work with Jake again and recommend Custom Onside to everyone.

  • Excellent Customer Service/Professional Work.

    Monica Muresan
  • Jacob gave me a bid to paint my house. He is courteous and very professional. Within a week the crew got started and finished in 3 days! Now my house looks awesome!

    Rock C.
  • Jake and his team went above and beyond in service. My backyard addition needed roofing as well as tearing off and replacing my homes roof, all while dealing with the solar panels and incompetent contractor delays and weather. They were always ahead of the game and took a lot of pressure off of me while dealing with a chaotic project. 5 stars does not adequately express their quality and professionalism.

    Timm M.
  • Highly professional team that made the process smooth and easy, and with great quality workmanship and materials. I would not hesitate to recommend Custom Onside.

    David Winter
  • For the service I did receive and especially for the service I did not. So often, roofing companies seek to land the job at all costs, especially at the cost of increased insurance premiums. By inflating, exaggerating, and in some cases fabricating roof damage, many roofing companies settle with home owners to do work that wasn’t necessary in order to turn a profit. Phil at On Side cut it to me straight, kept it honest, and was willing to value his integrity above all. After conducting a free and thorough inspection of our roof, he determined it was best not to file a claim with my insurer and ride out hailstorms until the damage truly warranted a claim. Phil represented On Side very well and I will remember On Side the next time I need the services they provide. Thank you!

    Eric Petty
  • They walked me thru the entire process, constantly checking in, work was done on time and very professionally, not one single issue or concern from inspection to insurance claims assistance to actual repairs, great company and people.

    Derek Gulley
  • Excellent service A++ guys highly recommend.

    Scott A.
  • Phil was great with helping us through the insurance process. Then Francisco came up with the team and knocked it out in a day! . I had a good experience with them and appreciated the follow up they did.

    Clayton Bedell
  • Phil and team did an outstanding job from the point in time I was first contacted, the estimate, dealing with the insurance firm and closing out the work. I would highly recommend Customer Onside for your roofing needs!

    Pete Loren
  • I couldn't be more happy with Custom Onside. From beginning to end, Custom Inside met all our expectations. Jake was very professional and always on time. I highly recommend this company is you're looking for a new roof.

    John Lam
  • Phil and Jake were absolutely fantastic with our recent roof inspection. Very knowledgeable, professional, and friendly. Highly recommend!

    Drew S.
  • Really not enough space to say just how exceptional Jake and the team at Custom Onside were. From the initial visit to the final inspection, Jake was on top of everything needed to get our roof completed. Always stayed in touch and responded quickly when we had any questions. 5 star ++ as stated above.

    Gene Silva
  • I only have good things to say about Custom Onside. They did great work. Professional, insightful, helpful, responsive and a pleasure to work with. They were very accommodating with our schedule and the work was completed quickly with no surprises. Thank you!

    Marc L.
  • Custom Onside contacted me to recommend that I had roof damage. They performed my needed roof repair and gutter installation. They did a very good job and I was very pleased with their work. I recommend using their services.

    Judith Aslasi
  • This company and specifically Jake, did an excellent job with our roof replacement. Jake walked us through the process and helped us with the insurance company making it basically painless. The finished roof looks great as well. We would/and have recommended this company to anyone needing a roof done.

    Brenda Smith
  • We hired Custom Onside to do repairs to our home due to damages from a hail storm and worked mostly with Jake Fairbanks. Jake is professional, thorough and pays great attention to every detail. He is also very knowledgeable of the insurance process and made the whole process stress-free! The job was completed in one day and cleanup was awesome! We highly recommend Custom Onside!

    Joy Golinski
  • We had our roof and several skylights, which had been damaged by hail, replaced this summer by Custom Onside Roofing, a small, local Boulder outfit. We are glad we did. Not only were they more nimble, responsive and quicker than the longer-established outfits in the area, but they were a pleasure to work with. From help dealing with our insurance company, to clear estimates and explanations of proposed replacement materials, to execution of the job (on time and meticulously done), everything was smooth and met our expectations. They even saved us money on future insurance premiums by suggesting we re-roof with hail-resistant shingles. Highly recommended.

    Rolando Garcia
  • A perfect job at a great price! Always on time, and actually did more than I asked for! I had them come back for some small stuff and they did a great job! I very much recommend them!

    Jerry Amaro
  • I have nothing to say about Jake but good things. His business is run in a professional way but with heart. If you are looking for an honest and warm person to do your roof or take care smaller problems such as leaky spots on your roof he's your man.

    Janet Brown
  • The first meeting with Jake, he wore a mask, he was professional and courteous. He gave me a bid to paint my house and within a week the crew, started to prep the 47 yr.old house. What a great father-daughter team! Just 3 days later my home looks awesome! Jacob come to look at the finished job, I asked him to touch up a small area, he gladly got his ladder, paint and brush, and put another coat of paint as needed.
    Great job! I will definitely refer Custom Onside Roofing and Exteriors!

    Tereasa Medina
  • Jake Fairbanks and his company did a fantastic job at my home. They roofed a major remodel addition to the back patio plus replaced the house roof all while helping and dealing with solar, weather and incompetent contractor delays and logistics. Anyone can put on a roof but Jakes' eye to service was beyond the norm as he consistently planned ahead, kept us updated and informed, and went out of his way to co-ordinate with the other companies involved. I would hire Custom Onside again, 100%.

    Timothy Meyers
  • I met Phil when I was riding through my neighborhood to the local coffee shop. We got to talking and he offered to come look at my roof, which I was already considering getting replaced. He told me that since there was a major hail storm the previous year and I had t-lock shingles, I could probably get it all replaced on an insurance claim. He made that a smooth and painless process and now I have a beautiful new roof for a fraction of the cost of what I would have paid for it otherwise. Phil and the whole Custom Onside team are my favorite experience since becoming a homeowner, just awesome!

    Ivan Bercholz
  • Custom Onside did a terrific job painting our home exterior and we were very pleased with Jake and the entire team. They were all very friendly, communicative and especially dedicated to making sure we were happy with their work. They made the whole job easy and stress-free. Custom Onside had competitive pricing with good understanding and documentation of the details. We would definitely use them again if the circumstance arises. Thanks!

    Gail G.
  • We had Custom Onside put a new roof on our house after the hail storms this summer. I would recommend Custom Onside to anyone needing a new roof or roof repairs and I rate them 5 Stars. They are very professional and go above and beyond what they promise. Due to the snow storms at the end of October I expected our project to be delayed but they sent a crew over to shovel the snow from our roof so the project could go forward on schedule. This was more then I expected. After the roof was completed they even cleaned all the gutters which wasn't part of the contract but it does demonstrate their professionalism. The new roof on our house looks great.

    John M.
  • Had a very nice experience with these guys. Had a relatively small area on the roof where the wind had blown away some shingles. I called for an estimate and two guys came out and quoted me a reasonable price. A few days later a crew came out and repaired everything for the price we discussed. Very competent and professional!

    Doug S.
  • Jake & Phil I could tell they were committed to their business. Very personable and professional. They were informative and helpful through the process. They guided me through the insurance claim and came out to meet with my adjuster which actually led to additional items on the claim and to be replaced. When we set appointments they were always on time and when I had a question they were quick to respond. Their install crew was clean and quick. Their crew chief was on site most of the job and was able to answer all questions. I would highly recommend Custom Onside if you are looking for a contractor for your roof or gutter replacement.

    John B.
  • Phil, Fernando and their team really did a great job on our barn roof. Faced with some deterioration challenges and difficulties with communication from our mountain site they overcame the hurdles and got our roof done quickly and on budget. It looks great and I’m confident that we are set for 30 years with no worries!

    Sterling B.
  • Jake and Custom Onside did a professional and thorough job of re-roofing my house. Jake went above and beyond to trim some troublesome tree branches and complete some minor repairs on a damaged soffit. He was also very helpful with clear communications through the scheduling and work. I highly recommend the company to other homeowners!

    Karen T.
  • We hired Custom Onside to do repairs to our home due to damages from a hailstorm and worked mostly with Jake. Jake is professional, thorough and pays attention to even the smallest details. He is also very knowledgeable of the insurance process and made the whole process stress free for us. The job was completed on time and the cleanup was awesome! We highly recommend this company!

  • My wife and I have already recommended them to family and friends, and we will definitely use Custom Onside in the future.

    Brian M.
  • I highly recommend working with Custom Onside, they go the extra mile in every way!

  • Custom Onside did a great job of helping us through the insurance claim process, choosing the shingles, and getting the mid and final inspections. We really had to do very little, and the communication the company provided was appreciated.

    Sarah A.
  • Top to bottom, these guys are the best. They understand everything about what they do. ... I totally recommend Custom Onside for anything they offer. They are good people and great to work with!
