One of their trucks illegally parked in the handicap stripe area. If I had to use my wheelchair I wouldn't be able to get in or out of my car.

The process to get the job done took months after my insurance approved the repair. The project manager assigned to handle the project, once all was sort it out, was great. The billing a nightmare. Sent me "past due" bills after 4months. Billing called me to collect difference, even as management told them not to contact me due to 3rd party All claims still processing/reconciling. 2 months later again another call from billing. This time I had all my excel sheet ready. They could not explain the payments and checks collected and ask me to send my reconciliation sheet. I said NO. They should have their own one and our numbers should match. This person could not explain where the difference of 2k : from what was approved and to what was paid...

We are sorry to hear about the billing issues and delays. Unfortunately, in dealing with insurance, sometimes there is no clear-cut decision and we may be left out with no communication at all. Please accept our apologies for any inconvenience this may have caused. It has all been handled and we do appreciate your business.

Very disappointing service from Shanco. No response after numerous calls. They tell you they do roof repairs but really are only interested in full roof replacement. And they did not even have the curtesy to call me back and explain, just told me a repair estimate was coming, and it never came...no call no nothing. Even after several follow up calls/texts. Terrible!!!

Good morning Mr. Sekel. I just left you a voicemail and look forward to speaking with you. This is not the way we provide service and my sincerest apologies. Thank you, Chrissie

I worked with Shanco twice in the past year—first to replace my roof (August 2024), then for new Hardi Board siding (May 2025). While I was initially happy with the roof work, things unraveled with the siding project. Though I signed the contract in January, the job didn’t begin until May, despite repeated emails and calls. No explanation was ever given for the delay. After installation, the siding looked fine to my untrained eye, but a construction-savvy friend pointed out sloppy workmanship: overdriven nails, underdriven nails, and other missed details. Shanco eventually sent their team back to fix some of the issues, which seemed rooted in poor oversight and a disconnect between sales and labor. The larger issue emerged right as the siding work wrapped up—I found mold growing on one of my bedroom ceiling. I suspected this was tied to the roof they’d installed eight months prior. Their siding supervisor told me that there was no active leak from the roof after checking the attic but couldn’t determine the cause of the mold. So I hired an independent roof inspector. He uncovered troubling problems with the roof: water-damaged plywood left in place, exposed nails where the mold appeared, shingles with nails installed too close to the shingle transition line, and missing overhangs. While the leak may have existed before the roof replacement, Shanco’s installation didn’t resolve the underlying issue—and may have made things worse. Again, they sent the subcontractor back to make repairs. My conclusion: some of Shanco’s work on both roof and siding was subpar, and I had to chase them to fix mistakes. One final heads-up: Shanco doesn’t inspect attics before installing a roof. They include this policy in their contracts, but it’s something homeowners should think twice about. A roofing system includes what’s underneath—and skipping an attic inspection might mean serious problems go unnoticed.

Solicited me for a roofing job even though the sign on my door clearly states that I do not want solicitors. If you won’t listen to me when you want my business, you sure won’t listen to me if I hire you. Also, there are signs at the entrance to my neighborhood forbidding solicitors like these. Don’t hire contractors who start out by ignoring local regulations and your requests.

Stayed home from work for an appointment bt 11 and 12 today for estimate on roof work. Selected this company as highly rated in Washington Check book and Google. Estimator was a no-show. And a no call. I called a little more than half an hour after the window expired. Got the answering service. Person was perfectly nice and professional. she tried to get a hold of manager and assistant manager who didn’t respond. Frankly, mistakes happen but too many roofers out there to start out the experience of this poorly.

One of their employees showed up to the job site in a Chrysler Pacifica minivan leaving her children locked in the car for an hour while she was up on the roof and socializing with her coworkers. Highly irresponsible. We have taken her tag and reporting her to CPS. You should be ashamed of yourself!

We had a minor leak in our bedroom ceiling so we asked Shanco to come inspect and diagnose. Derrick S. came out and did a free inspection and determined that it was actually a chimney issue. He did not charge us, was incredibly gracious, and exceeded our expectations of customer service. I will certainly be using Shanco anytime we have any roofing issues or needs.

Steve, who is the sales rep for Shanco did an amazing job coordinating things to have leaf guards installed on my gutters. Steve and his team made sure the work was done correctly and it absolutely was. Shanco Roofing is highly recommended for professionalism, response time and effective communication.

I've been told I'm not the easiest client to have. But a background in sales and services,.. I tend to do more research on the products on the market, and I ask a lot of questions before making my choice. A roof is a product once you have it, you don't return it and choose something else. At no time did Mark or Brandon or anyone else try and "Pressure Sell" me on making a choice or steering me to a particular product in their line of roofing. I listened, (and guys I had pretty much made my choice before) but I was looking for Honesty and quality. . I got both! Mark the Magr. Brandon and the entire sales and install team, were Great! they prepped before they started, dealt with the wind and cleaned up the area so well afterwards. Awesome job from beginning to end. I've gotten more compliments stares and the Roof and Gutters questions and plenty of Referrals. Truly Happy all around Thank you for your patience during this period and Thankyou for the Great workmanship!!! 100% Happy... and by the way.. They are Comparatively priced. (New Roof and Gutters) 5 Stars across the Board

Update: Galo reached out less than 24 hours after this review to address our concerns. By the end of the day he had coordinated with his team to have the damage to our carport ceiling repaired. In the end, Shanco made things right. We hired Shanco for a full roof, soffit, and gutter replacement and aluminum wrapping of our trim after great responsiveness and communication with sales rep Steve. Unfortunately, things went downhill once the work actually started. We had multiple concerns with the quality of workmanship with the roof replacement in particular and had to raise our concerns multiple times with project manager Galo to be taken seriously. The crew also caused damage to our home in multiple areas including leaving an open hole in the ceiling of our carport shed and doing a "quick fix" to an area of siding they damaged during roof replacement, which we only found acceptable because we plan to replace our siding in the near future.

PRAISE for everyone at SHANCO, from David Poole in sales to Project Manager Alejandro Alvarado and his excellent Team of Roofing Installers. Our new roof was installed quickly and efficiently, using the premium GAF Lifetime Roofing System including GAF Snow Country Ridge Vents. You’ll love how Shanco provides great documentation of their work with many before and after photos. While the latest National Customer Rage Survey revealed that 77% of customers reported experiencing a product or service problem in the previous 12 months, Shanco stands out as a reliable and trustworthy company. Many thanks (y muchas gracias) to Shanco and its team for our new leak-free roof…

Tyler McPherson from Shanco inspected my roof and immediately applied a temporary fix to prevent further damage — which I really appreciated. From the very beginning, he was professional, responsive, and knowledgeable. He guided me through the entire roof replacement process, helped me understand the financing options, and made everything smooth and stress-free. Christian, the sales representative, was also excellent. He clearly explained all the roofing options and proposed solutions that fit within my fixed budget. The pricing was fair and reasonable, and I felt confident that I was getting great value for the quality of work. When it came to installation, Alejandro Alvarado and his crew did a fantastic job. They worked efficiently, paid close attention to detail, and made sure the cleanup was spotless after the job was done. Overall, Shanco exceeded my expectations — great communication, honest service, and top-quality results. I truly appreciate the professionalism of Tyler, Christian, and Alejandro, and I highly recommend Shanco for anyone needing reliable roofing work.
