Frozen Flat Roofs

Today we responded to an emergency flat roof problem in the east-end. Store manager was disappointed and tired of chasing the original roofing company who installed the roof. It was in the late afternoon and thunder-storm alert was issued.

We examined the water damage from inside to pin point the possible location of the leak but nothing added up. Original leak was coming in from the second story and working its way all the way to the main floor. We noticed the water dripping by the duct-work on the second story and went up on the roof. Roof drain was very close to the entry location so we were assuming the problem was the drain but it just didnt make sense how the water was going onto the duct-line. After inspecting the entire roof we did find some overlapping seems that did not have any bleed marks from the torch. Torch-down membrane must have a 1/4 inch bleed-out indicating that fusion is complete and it is now one piece.  Found the location of the drain from inside the building and there was no signs of water or moisture. Because the building was all cut-up it was kind of confusing where everything was located on the roof. Once we figured out where everything was located on the roof, it was obvious that there was an issue with the A/C unit.

I have seen this happen before where the ac unit bleeder gets clogged and water works its way in the building. As soon as i removed the pvc bleeder water was gushing out of the ac unit. This pvc pipe is designed to build pressure for the pump to force all the condensation and water out of the unit. Trap was clogged from all dirt and debris and water pooled up inside the ac unit and started to leak inside. We cleaned the trap and installed it back i its place. It took almost 5 minutes to leak to stop. Knowing that there was 5 ac units were up on the roof, we cleaned all 5 traps and installed it back in its place.

Poor maintenance of your roof and anything that is located on your roof is a potential cause for leaks. Always replace the ac filters regularly and clean out the pvc traps to avoid similar problems. Check all drains to make sure it is not clogged from dirt and debris. Always hire a professional to do the job.

If you live in Ottawa and the valley you must have seen the layers of snow and freezing rain combination. Sometimes you may think there is a problem with your roof but actually it’s the unpredictable weather that we are having.

If your house is a bungalow and has more than average number of valleys on your roof, get prepared for the snow and ice build up during winter. Any house or building can have ice dams or more than average snow build up.
If you ask what causes ice dams i can explain it briefly. There are many reasons behind ice dams and it changes from house to house. If there is not enough fresh air in your attic, it can build condensation and turn into ice dams. If your vents are covered with snow and attic air is not venting out, it will help ice dams to form. If you have poor ventilation it will definitely form ice dams. Number of vents and amount of vented soffits must be balanced, if your attic is not same or close to temperature outside, it will help the ice dam. If you are not sure what it is or need an advise from a professional, contact your local Ottawa Roofers and they will be more than happy to consult you about your needs.

It is always in your best interest to maintain whats yours. You may have to do roof inspection once a year to be on the safe side. Your roof protects you and you should do the same in return and maintain it. Hire a roofing contractor to remove all the snow and ice dam off your roof before spring or you may be facing a bigger issue if there isn’t any ice and water shield or felt paper. Now days builders are saving nickles and dimes.  I have not seen one house yet with ice and water shield or felt paper all around. But that’s where i take over and do it right.

It is impossible to know when it will happen but it is your responsibility to prevent it and have your roof inspected. It takes a while for water to work its way through. Homeowners are often notice the water damage by coincident. After noticing the yellow stains on the ceiling most people would ignore it and wait to see if it would get bigger before hiring a local roofing contractor. If you notice a yellow stain on your ceiling call for repairs immediately. Not having the problem assessed can lead to mold in your attic. Problem can be solved before further insulation and plywood damage can get bigger. Time to time crack on the shingles are not visible to naked eye and problem area needs to be inspected while its raining or water test needs to be done by two people. Once the problem area is detected further repairs can be done by replacing the damaged shingles in that area.
If the yellow stain is ignored eventually multiple yellow stains will occur and the repairs will cost you an arm and a leg. Always have your roof inspected by a roofing contractor prior to every winter.
