We had such an amazing experience with Ajax Roofing! From start to finish, their customer service was outstanding. The team was incredibly kind, helpful, and professional every step of the way. They took the time to answer all of our questions and made sure we felt comfortable and informed throughout the entire process. Their knowledge and expertise really stood out — you can tell they truly know what they’re doing. It’s not always easy to find a company that combines skill with genuine care for their customers, but Ajax Roofing absolutely does. They took the time to explain all different options and educated us on each. We felt very well informed and comfortable with the decisions we made. We couldn’t be happier and would highly recommend them to anyone looking for reliable, trustworthy roofing services!

Amazing work done, making sure the soffits around the roof were seal properly despite the weather to ensure and avoid a racooncoming back into the attic area. Brad was great and really took the time to make sure everything was done correctly. 100% recommend them if you need an honest and reputable roofing company. Thank you Caleb and Travis to look after the roof and attic

I had the pleasure of dealing with Caleb during our roofing experience. Caleb was very thorough and extremely kind, even noticed how poorly vented our fan was and made sure it was fixed and checked the other one. The roofing team were true stars, so clean, so efficient, they even rescued my sons foam rocket that he lost on the roof and left it at the door for him. We also have 3 dogs, they were very patient with letting me take them out for bathroom breaks. Thank you Ajax Roofing for a great experience and great quality!!
