I am very impressed with the service and responsiveness of Sanderson Roofing. I asked for an estimate from 8 different roofing companies in Ottawa / Gatineau, many of them had been referred by coworkers and neighbors. However Sanderson stood out. They came to see the roof the next day after I submitted for a quote online. Unlike other companies, the technician who came, brought two series of actual sample catalogues with all the different colors samples (not just the prints), and then they emailed the quote. The price was quite competitive and less than most of the others quotes I received these days, but still $1000 more than 2 quotes. Sanderson was generous enough to offer 10% discount for their 125th anniversary! They further lowered the price so their quote became the most competitive one possible in the market. Not to mention that other companies had only 10 or 15 years free workmanship warranty, but Sanderson has 25 years (and of course 50 years for the shingles they use, as they are the top quality ones from IKO or GAF Timberline HDZ products which are the leading brand and quality shingles currently in the industry. They started the job the next business day after the price was fixed. The roofer team (3 people) were very professional and worked very clean and quick. They could have finished the whole job in one day, but were required to stop at noon due to High Temperature warning. So in two half days they finished and indeed cleaned very well the entire site, including the eaves through, deck, grass, everywhere. Their invoicing and method of payment (cheque - Retransfer - Credit Card with no fee) was more than other companies can offer, and the administrative services of office (in registering the factory warranty 50 years and providing the company 25 year certificate of labor) was super fast and professional and great experience.... Something you can not really expect from this industry.... But Sanderson are in business for 125 years and you can feel relaxed that they will be around again within decades if indeed your roof had problem during the warranty period. This, you are not sure with other small or less known companies, even if they offer very low price..... Thank you Sanderson for such great service... I cannot be happier than this!
