Awful!

You should go over substance use with your employees. The roofs great but smelling weed at 6:45am and at noon is not great for business!

I had my roof done 4 years ago. There is supposedly a 5 year warranty. I noticed a small leak in an upstairs bedroom in December. I called and left several messages. I had one return call which was not helpful and then nothing. It is now March and still no reply. I ended up hiring another roofing company to fix the problem before it became more serious. I would not recommend them.

I have never used them. But they recently did a neighbours roof. And in our community alot of us have small children. And these guys were constantly swearing. Not acceptable. You are supposed to be a professional company. Act as such. Also. …

After the storm yesterday, I immediately contacted Jonescu Roofing. I figured they would have many calls w all the damage here in Guelph. I left a msg since it was after hours. Dave responded early this morning with a text and was on the roof by the afternoon repairing where the shingles were torn off. He was quick, efficient, no muss, no fuss & you'd never even know there had been someone here working. Everything was left neat and tidy. Dave has done more than one roof for our family & wouldn't hesitate to use his services again.

Dave was very helpful in finding a date that worked for us and our tenants. Property was left without a trace of there having been work completed. Thanks Dave!

We have had Dave re-shingle 2 of our homes for us over the past few years and can't say enough about how timely, professional, cost effective, extremely tidy and clean while the work is underway and just an all round nice guy! We would recommend Dave to all our friends, family and my client base!

Jonescu roofing has done completed work on 2 of our homes plus my in-laws. Quality and workmanship is definitely great. Dave is down to earth and lets you know if there were any issues removing the old shingles. Time to complete the re-shingling was very good. Day + 1/2 and that was because of the weather. I've always appreciated the care they take to clean up afterward. Dave is always busy so he might not get back to you right away but I trust him and his team. Thanks for a job well done.

Dave and team showed up on the date and scheduled time. They left the yard clean - you wouldn’t know they were there except for the beautifully done new roof on the house.

Absolutely first rate service and attention. Great to see the site cleaned up before the end of each work-day. We received competitive pricing and it was a no muss, no fuss experience. We have added Dave to our list of trusted service …

Where this page comes from
Every figure above is Google’s, captured on 24 September 2026. The star average and the 12 ratings behind it are counted by Google across all of its reviews. The review text on this page is a sample — we hold 12, of which 11 have any text — and it is not everything Google shows.
Roof Warden does not verify licenses, bonds, insurance or workers’ compensation cover, and nothing on this page should be read as though we had. Confirm those directly with the contractor and with your state or provincial licensing body before you hire anyone.
There is not much data on Jonescu Dave Roofing. A short record here means our capture found little — not that there is nothing to find, and not that the business is new or inactive.
