Letter of recommendation:

I’m writing a letter of recommendation for CLS roofing and Chris. We own a 110 year old Victorian home in downtown Ottawa.The roofing structure is complex: some flat roof, some shingled as well as a dormer and door coming out to a third floor  deck above the flat roof which was replaced. Upon discovery of a leak in the flat roof/dormer structure,Chris and his crew came in and did a great job removing the old deck and roof and replacing it. The work was done quickly, efficiently and with  high quality.The site was left very clean and Chris and his crew did a good job managing the job.

During the job, it was discovered that the original design of the existing shingled roof/dormer was not optimal and that it would  be best to change the sloped roof, so water would  be diverted away from the corner of the door and ensure waterproofing and not allow for ice buildup in the winter (which was a problem that was occurring each winter). Chris sent in his crew,they addressed the issue and waterproofed it, so we won’t have ice accumulation and significant  water hitting the corner of the door as it had been. The work they did to ‘restructure’ the roof was done very well,it not only looks great, but is very solid in terms of diverting the water/ice and I’m confident in the work that Chris’ crew did.

As the owner  of several rental properties,I’ve worked  with many tradespeople, and companies. I must say that Chris and CLS were not only very responsive, but they did a great job understanding the issue, and resolving it,as well as being proactive  in making a recommendation for how we can avoid potential future issues. Please feel free to contact me if you have further questions or would like additional info.
