Emergency Roofing Repairs

Wind Warnings and Torrential RainFall has been causing roof failures in British Columbia, while meanwhile in Southern Alberta high Winds are Blowing Shingles, Shakes, and Tiles off Roofs Again.

This week has been tough on roof systems from the West Coast all the way to Saskatchewan. Our call center has been over-whelmed with wind related roofing repairs calls along the West Coast including Victoria, Vancouver Island, Vancouver, Vancouver North Shore, and in the Fraser Valley. While in Southern Alberta such areas like Lethbridge, Medicine Hat, Okotoks, and even into Calgary have been experiencing wind gusts of up to 120 km/h.

The unusual high winds have been tearing shingles off roofs and causing general havoc with a variety of roofs types. We have received calls with complaints of skylights blowing off or leaking, roof vents, flashing, and even roof hatches needing repair.

With the heavy rain on the West Coast, this has caused flat roofs to fail, this particularly has applied to those that have drainage issues or drains that are plugged. With the cycles of having warm air thawing to only freeze again due to the Chinooks in areas like Calgary, AB, this has been resulted in our 24 Hour Toll Free Emergency Roof Repair line to receive several repair calls.

We are finding that Roofs with improper attic ventilation are having condensation issues to areas even as far north as Edmonton and flat roofs are requiring more maintenance to clear drains that are freezing over with ice.

Flat Roof Drainage Problems: Flat roofs unfortunately do require some regular maintenance, especially in high winds and freeze-thaw cycles.

Roof Drainage: The roof drains are prone to clog from leaves, tree branches, and with the ice and snow melting and freezing on the roof. Drainage problems on flat roofs can also be compounded by an inadequate slope of the roof. Nonetheless, a spring and fall maintenance of the roof is key to ensuring the roof bears well during bad weather. Click here to see our  Flat Roof Maintenance check list.

Roof Inspection: Extreme winds, heavy rain-fall, and snow and ice melting should trigger an inspections to be completed. It is preferable that this is completed during the storms to ensure our technician’s ability to see if the roof drains are clear.

Roof Slope Problems: With improperly sloped flat roof systems, there are solutions to mitigate these issues. An improper roof slope can be examined with our technician at the time of inspection or while we are performing maintenance to your roof.

Sloped or Pitched Roof Attic Condensation Problems Attic condensation repairs or remediation tend to be a more involved process requiring a number of steps.

Solving Attic Condensation

Your attic require proper ventilation. You need to check the intake air typically at the roof soffits to be sure that there is enough air coming in to your attic space. Be sure to check that insulation is not covering the air from entering your attic by following the air flow along the roof sheathing to where you come to the ridge or peak of the roof.

Check the exhaust vents (typically by each square foot or along the ridge) to be sure they are not plugged with snow and see if there are enough roof vents. You will need about 1 square foot of roof venting per 100 – 300 square feet of attic. A calculation commonly used by our roofers for attic / roof ventilation is 1:250. If the air vents exhausting the intake air is appropriate then you need to check the vapor barrier of the attic. It cannot be compromised and be letting warm air in.

Warm air rises through the attic into the roof sheathing. The snow on the roof then melts and creates ice dams. The ice dams then back up under shingles, shakes, and tiles causing leaks in to attics and then ultimately in to your house through the ceiling. If none of these problems can be found in your attic, it is best for you to then call the experts.

High Wind damage and Roof Repairs to Shingles, Tiles, and Shakes Repairing Damaged Roofs: Ultimately, after the installation of shingles, tiles, or shakes are complete and the winds begin to increase, you can now face blow-off problems. The best we can do is repair the windblown damaged roof.

How to Shingle a Roof: Prior to having your roof replaced, it is a good idea to know the specifications and the proper way to shingle a roof to ensure your roofing contractor is in check at time a roof replacement is required. Our website has a series on How to Shingle a Roof that explains the process of shingling for areas with high winds and how to avoid costly repairs due to wind damage.

Roof Underlay: Beyond the actual installation principles when replacing your shingles, shakes, or tiles there is the issue of the roof underlay. If the proper roof underlay is used and is installed correctly, then one does not have a concern in regards to shingles, shakes, or tiles being blown off. The roof underlay or membrane will keep the roof water-tight with-out the shingles so no leaks occur.

Shingles for High Winds: Finally, there are roofing shingles available that are designed to withstand high winds. Shingles like the Malarkey Legacy have high wind ratings of up to 170KM per HR which gives areas like the West Coast, North Shore of Vancouver, Calgary, Lethbridge etc. some advantage over the winds that damage roofs every year.
Should you have any questions or concerns regarding your roof, our office is always able to provide over the phone advice, set up inspections or arrange for a complete repair.

Flat Roof Patios – Roof-Top Patios, Decks, and Terraces Roof Top Patios, Decks, Terraces

The challenge with an outdoor patio or deck on a flat roof is that the waterproofing material or membrane used on the substrate/decking has to be done perfectly. The drainage for the low slope, and the decking material put on top has to be precise

(Some patios we service are on a flat roof itself or on a terrace balcony, while others could be on a garage.)

There are various types of rooftop decks and the different waterproofing membranes that can be used. There are flat roof membranes such as 2 ply SBS Modified Bitumen, 4 ply Built up Roofing, EPDM Rubber Roofing, PVC which is a

poly vinyl chloride, TPO which is thermal plastic. There are also products that can be applied to seal a substrate such as a concrete substrate with membranes like hot applied rubber asphalt systems and cold applied liquid rubbers (elastomeric coatings etc.)

The next issue that you would face on a flat roof would be the drainage issue. All repairs would need to be done with extreme precision in order to allow the proper drainage and slop.

After you have chosen the type of rooftop deck, the appropriate waterproofing membrane for on the substrate, and the drainage is correct. You then have the issue of what you place the membrane on itself. You will need to determine if any decking material on the membrane is required. We have seen customers use a variety of surfaces on rooftop patios, with everything from ceramic tile, paving stones, treated lumber, composite tiles, to Spanish tiles and granite.

Our recommendation to those looking at repairing, installing, or replacing a rooftop patio is to speak to a waterproofing expert first. The Home Depot or Lowes store decking material associate may be able to provide some suggestions on what tile to use, yet they may not understand the proper flat /low slope roof waterproofing and drainage practices. Roof top waterproofing for a deck system is different than normal flat and everyday roofing. With rooftop decks and patios the two worlds meet. The staff at General Roofing Systems Canada can assist you in designing a rooftop patio system that should last 20 or more years. In order to achieve these results, it is vital that owners do not try to take the least costly way out. When Owners begin to cut corners in an attempt to save costs that is where the errors occur and end up being more costly later on due to future repairs.

Below we have a report that came in to the GRS office from a roof repair technician. It shows a rooftop patio that is not very old and was installed incorrectly. Due to the improper installation, the owner is now having to pay for costs that could have been avoided. As a result of this the deck material, patio’s flat roof membrane and the sheathing/substrate will have to be removed and replaced. There is even the possibility of remediation for mold and trusses being replaced.

We hope that this article will help home owners to be more aware when purchasing decking materials and to contact a waterproofing specialist first. This tip will help you to enjoy your patio/deck for years to come without the need for repair.

Initial Client Inquiry:

I have a 300 sq. ft. rooftop deck that currently is leaking.  I was wondering if I can get someone to have a look and estimate what is required to resolve the problems we are having.

Assessment, July 27 2011:

The roof top deck is having leak problems. The rooftop deck is 95% tiled. Under the patio tile is a  deck-type waterproofing membrane and then plywood substrate. The worst area of the rooftop deck is in front of the sliding doors of master bedroom. It is not tiled. The roof top deck is covered in a paintable rubber deck membrane (low cost liquid coating). Where the tile and deck meet is a metal flashing that is letting water in. The wood decking is rotted. Not sure if you can put grout on PVC decking material, I suspect when the rooftop deck was originally tiled this is probably what caused the problems. The homeowners don’t want the ceramic tile on anymore. To fix this rooftop terrace/deck it needs a whole new rooftop deck replacement. The deck needs a tear right to the substrate and inspection of the substrate wood. This terrace is unable to be repaired and will required a full re-do

Below is an article describing the troubles that can arise with any and all roofing situations should you have with work completed improperly.
We know that every trade has its problems. Poor installations, normal deficiencies that occur, and then unprofessional workers. Unfortunately, the flat roofing trade is no exception to such occurrences.
The new home in this flat roof inspection report completed by our roofers yesterday is a victim of the exact problems mentioned above. The home in the below pictures is quite new and  was architecturally designed. However, the roof was installed poorly (2 Ply SBS Modified Bitumen) resulting in leakage. We suspect this flat roof has been leaking every time it rains or snows since it was first built.
As a result of this poor installation, the homeowners will now have to face extra costs in order to replace it all together.

Initial Inquiry:

We are looking for a replacement quote. needs repairs for torch on flat roof, client requires  the roof replacement completed within 2 weeks. Highest section of house is leaking and flat roof installed incorrectly.  Flat roof seams aren’t sealed.

Field Report, July 27 2011:

The upper smaller flat roof (SBS Modified Bitumen) on this home is completely past the point of return and a roof replacement is required . All the roof membrane seams are lifting and there is no bleed out at the membrane seams. All termination points along perimeter of the flat roof are not torched down properly. All intersections are lifting and there is no slope of roof toward scuppers. The upper roof needs to be replaced completely and should be ripped down to the deck.  It also requires a cricket (slope towards roof scuppers).

The Lower canopy roof (Modified SBS Torch On) over the main entrance of the home is in the same state as the top roof.  The roof is not torched properly, it also slopes down toward house instead of away from.  There is only one roof scupper at the high point of the roof corner which is not draining. The drainage on this roof system is very poor. The lower roof needs another scupper and or a drain in the North corner, this also needs to slope away from the house. I recommend another rip and a full roof replacement to this section also. In order to replace the roof systems we will need to take all cap and detail metal off  as it is tied into the stucco!
