Choosing the right Skylight Installer or Skylight Repair Technician

The real review of skylights or anything else we use on a daily basis is primarily determined by the installer. The number one word of advice we can give is to choose  the right contractor. A roofer that installers skylights regularly is your best bet, as the roof membrane, flashing, curb, and system itself may all be one issue. Once you have the right technician installing your skylights, the issue of choosing a skylight brand is the easy part. Most skylight brands are competitive in price and perform well.

At General Roofing Systems Canada, Velux Skylights are a standard. We use or recommend Velux Skylights regularly for these reasons:

  • Velux skylights offer suitable dependendable, and predictable performance. They have an excellent warranty structure and service to back it up. Sure, there may be specialty manufacturers that may suit a specific situation or performance requirement better, but all in all, Velux products are one of the standard recommendations we make.
  • Readily available. Velux is well-distributed in Western Canada and their service is exceptional.
  • Great track record. Founded by Villum Kann Rasmussen more than sixty years ago, Velux Skylights have a history of performance and dedication.

Skylight repair and installation is a trade in and of itself. One of the most common calls that our call center receives is the “my skylight is leaking” call or the “I hired them to install my skylight and this went wrong, and now my skylight leaks.”

Repairs and Installation – Who Do You Hire?

Our recommendation for skylight repairs and installations is to hire a repair company that has roofers who also know, and are experienced in, skylight repairs and installations. The reason is that skylights are installed on a roof – more specifically, they are typically installed on a roof curb (the skylight is mounted to the curb), and the roof curb has special flashing designed for around it and/or the skylight, with the roof curb being attached to the roof system. After all that, the roof curb (if required), the skylight flashing, and the roof membrane must all be installed properly so that your home or business does not have a skylight leak or a roof leak. We continually recommend an expert roofer that is also an expert skylight installer to be the best skylight repair and installation technician you can get.

The Cause of Skylight Leaks

Skylight repairs are more difficult at times than our roof membrane repairs – tricky to say the least. The following are some of the causes of skylight leaking which need repair:

  • Leaking due to flashing failure/flat roof membrane repairs.

The skylight flashing installation is typically the cause for a skylight leak. Repairing skylight flashing can be challenging. The skylight flashing may be a special order, or the skylight flashing will likely be apart of the roof membrane. In the case of commercial skylight repair or residential homes with flat roof skylights that are leaking, this can become more of a challenge. If the skylight leak is on a flat roof installed skylight, you may need a certified SBS modified torching roofer to deal with the skylight flashing and the roof membrane, or in the case of TPO, EPDM, PVC, or even tar and gravel roofing scenarios, quite often you will need a specialized roofer and the skylight repair coordinated in one job.

  • Leaking caused by roof membrane failure at penetration.

Roof membranes break down over time. Your skylight may be leaking because your roof membrane was either installed incorrectly or it is simply breaking down from age. Nonetheless, you will need a specialized roofer to repair the roof membrane. The shingles or flat roof membrane will require the right roofer with the right skills for the repair.

  • Leaks caused from failure.

Skylights, like everything else, age and break down. It may be that some caulking repair is required at the skylight, or the flashing needs repair, or the curb has rotted and needs replacing. Typically, if age is the cause of the leaks, with advancements in technology, you are better served replacing your skylight versus repairing it.

  • Leak caused from condensation.

Skylights were not made like they are now say… twenty years ago. New skylight technology deals with most condensation issues and there are less repairs needed as a result. However, not even the best system can stop condensation from affecting it if your attic ventilation is incorrect or something else is causing your house or attic to not vent correctly. Condensation in your attic space, home or business can be complicated to repair. It can be similar to a wiring issue in a car: frustrating.

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.

Solutions for Roof Repairs, Attic Condensation, and Roof Drainage Issues

There are some solutions we can offer to help with the various problems roofs have this time of year. However If you cannot solve the repair or maintenance issue by yourself, call our 24 hour emergency roof repair toll free number at 1.877.497.3528 and schedule a repair person to attend.

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.
