Testimonials
Posted on Google Tom DufekTrustindex verifies that the original source of the review is Google. We had Blue Line do a full roof replacement for our home and could not be happier with the customer service from John or the incredible hard work by the crew during installation. From consultation to site cleanup. Everything was very easy, the communication was on point and the roof looks absolutely beautiful. I could not recommend John and Blue Line Roofing more! You will not be disappointed.Posted on Google Brock NeidererTrustindex verifies that the original source of the review is Google. No one ever really wants to get a new roof, but at some point, sometimes you have to. I was dreading going through this process and quoted 5+ companies in my area. Blue Line was by far the most customer centric company I quoted. Mike Smith was who I worked with, and he took the time to educate me about my roof, what to look for, answer any questions, provide shingle samples; the whole 9 yards. Most of the other companies I spoke to just provided quotes and gave the standard "We provide the best quality work etc. etc." without really explaining everything that had to be done. Tearing off a roof and putting one on may seem like as easy job just because it is only 1 day of work, but there is so much more than that. Mike took the time to compare warranties on different shingles, workmanship warranties, timeline/weather to install the roof, weather and algae ratings between shingles and so much more. Mike was available via call/text whenever I needed, and response time was usually in a matter of minutes. Due to weather we had to install on a Sunday and Mike was at our property as the crew was getting set up and stayed around majority of the day to make sure the crew had what they needed, I had what I needed and most of all he walked my property along with my neighbors all day to pick up any debris from the roof - he even came the next morning to do a quick walkaround and spent another hour or two walking the area to make sure nothing was missed. Blue Line has over a decade of experience in roofing and exteriors and their quality of work shows - also a Veteran owned business! I would recommend anyone looking to get exterior updates to contact Blue Line/Mike Smith!Posted on Google Jacki GrubbTrustindex verifies that the original source of the review is Google. We had two small cracks in our siding because it was brittle from the weather. We reached out on Thursday morning and by Friday afternoon, our siding was repaired. Quick response time, great price, and wonderful workmanship. Will be using them again!Posted on Google Charles FriedmanTrustindex verifies that the original source of the review is Google. I have read the reviews by my neighbors, and rather than repeat everything I'll just say that I completely agree with the comments about the outstanding service Dylan and his crew provided. They even helped me with a completely unrelated problem. Thanks, guys.Posted on Google S<rustindex verifies that the original source of the review is Google. We write to highly recommend this business, Blue Line Roofing & Exteriors & especially Dylan, our area representative who went above & beyond to secure replacement roofs for ourselves & many neighbors after a hail storm hit our area in early June 2023. Dylan's experience with identifying hail damage & dedicated follow though with all our many insurance companies in the community resulted in both immediate approvals as well as overturning initial denials in our neighborhood. Dylan's approach to initially evaluate the roof, document with photos and chalk markings & subsequently returning to meet personally with the adjusters & their inspectors or engineers, including joining them on the roof, resulted in successful claims. We could not be more satisfied. Thank you Blue Line & Dylan! SnL Harrisburg, PAPosted on Google Amanda ValentinTrustindex verifies that the original source of the review is Google. We recently we had the need for roof, gutter, siding and soffit repair at our house. Even if my husband wasn't hindered by physical limitations; roofing, soffit, and a hole in the side of our house are definitely over our heads (literally and metaphorically!)!! So we called Blue Line Roofing and Exteriors. He sent his resident expert Tito, who was without a doubt one of the most professional, knowledgeable, and stand up service rep we've ever met. Not only did he save us a ton of money, he took the time to explain his process and took preventative maintenance measures to help alleviate future issues. Hoping our roof last a long time, but they've got a customer for life.Posted on Google peter mTrustindex verifies that the original source of the review is Google. Just had a roof replaced by Blue Line after hail and wind damage. The contact person - Dylan was very good at working both with me and my home owner's insurance adjuster to ensure a smooth project overall. The crew that did the roof completed the work very efficiently and effectively in one day and were also very careful in protecting plants & patio etc. The post work "tidy up" was completed the same day and was very thorough indeed. The company's use of technology to share all required documents and to facilitate payment via QuickBooks was very helpful as well. Overall it was a very good experience and I would recommend them as a good roofing contractor.Posted on Google Jenna WantzTrustindex verifies that the original source of the review is Google. Great companyPosted on Google Jeremy EnglehartTrustindex verifies that the original source of the review is Google. Excellent experience! This company uses top quality products, very professional and wonderful to work with. A special thanks to Dylan for always being available for questions and a top notch representative of this great company. Thanks for the great work on the new roof!Posted on Google Peter WambachTrustindex verifies that the original source of the review is Google. I would highly recommend without any reservations whatsoever Blue Line Roofing and Exteriors. My experience began with a representative of the company Dylan Sheehan doing an inspection of my roof because of hail storm damage in the Harrisburg area at the beginning of August. Dylan examined my roof and explained the damage to me and I immediately put in a claim with my insurance company. The company assigned an adjuster to the claim and Dylan met with him when he came to review the claim. I appreciated Dylan’s offer to return and meet with the adjuster and shortly after I received notice that the claim was approved. Dylan went beyond the call to do the follow-up and to keep me informed. The Blue Line roofing team show up as scheduled, and again, Dylan appeared to insure that all supplies were on site and that the crew began the work as scheduled. Blue Line is a GAF approved installer, which extended the warranty. The work was done in one day, including clean-up. Dylan stopped by to make sure that everything was to my satisfaction. Dylan Sheehan should be cloned as an example of total professionalism from start to finish. Again, if you need a roof, call Blue Line Roofing and Exteriors, you won’t be disappointed. Peter Wambach
