Dave is a client of ours who owns a flat-roofed home in Sherwood Park, Alberta. He noticed that his roof had been leaking for a few months when he got in contact with us. Whenever it rained, he saw water leaking through the soffit and behind the eaves troughs of his tar and gravel roof. On the inside, his ceilings were developing water stains. Dave wanted to get the problem fixed, so he had us come in to do an inspection and schedule a repair.
So, what was wrong with Dave’s roof?
When we got there, we found that a whole corner of the roof was rotten, which we could tell because it was soft to walk on. A roof will only be soft for two reasons:
- It’s rotten – likely from all of the water accumulation or
- It’s made with paper-backed, rigid fiberglass insulation. Stiff fiberglass insulation isn’t necessarily soft to walk on, but it’s spongy. It’s also only used on commercial buildings, so since Dave’s roof was on his home, this wasn’t the reason for the leaks.
The rot had created holes in the roof that were allowing water to leak and rot the trusses and the wood deck. It had compromised the insulation and there was also damage to the fascia board.
We told Dave of our inspection results and told him how we could fix it and that we would get back to him with a quote.
Once at the office, we drew up a quote and sent it to Dave, along with our WCB and liability insurance numbers. Dave sent back a couple questions he had about what we do with the rotten parts and how we were going to do the repairs (Read our FAQ for answers to his questions and more.) We cleared up everything for him and got together to sign the contract.
The Day of the Re-roofing
On the day we scheduled the re-roofing to be done, Dave was there to answer any questions we had as we worked, and generally just be around to watch the job. It’s not essential for you to be home during the job, but it’s up to you.
We brought a crew of 5 to do the roof: A couple labourers, a few apprentices, and a journeyman/foreman. Meet some of the guys on our crew.
Since this was a tar and gravel roof, we used the usual roster of equipment:
- Roof Rippers
- Table saw
Plus additional woodworking tools like a table saw and a skill saw.
First we took off the tar and gravel. It turns out it was at least 25 years old, which is a fair amount of years for a tar & gravel roof. When the roof was cleared of all the old material, we put in an SBS roofing system, which is a little cleaner and modern than tar & gravel and we added some rigid insulation.
The end result is a roof that is maintenance free for 10 to 20 years, but it’s always good to check on your flat roof. With some proactive maintenance, this type of roof will last at least 25-30 years.
Throughout the installation, the journeyman and project manager inspect the job to make sure everything is done according to code. When the job was finished, we reviewed it with Dave, who was very happy with his new roof.

Avoiding Future Roof Problems
In order to make sure he didn’t run into problems in the future, we scheduled a roofing inspection every couple of years, which is a great idea for anyone because repairs can often be done to extend the life of your roof.
