Photo Journal: Flat Roof Leak Inspection Edmonton AB, March 2014

Flat Roof Leak Inspection Edmonton - Below you will find a photo journal and emergency roof repair assessment from our Edmonton roofing repair crew at a commercial roofing site. Although the call began as a tar and gravel flat roof leak repair, the extent of damage escalated to the client requesting a quotation for flat roof recovery or replacement options. More field reports will be posted as they become available for this site. Regular Flat Roof Maintenance Will Save You Money. If you own a flat roof it is critical for you to conduct regular inspections, maintenance and repairs as needed. You will save considerable money if you do this twice per year. The reason it saves you money is that a complete flat roof replacement is expensive and 9 in 10 times had maintenance been done the replacement would not be required. If you do not do regular inspections and maintenance you could face a catastrophic failure which has occurred to this roof below. Simple spring and fall inspection and maintenance would have avoided a costly re-roof. Click here for a proper flat roof inspection and maintenance check-list. Emergency Flat Roof Inspection Edmonton, March 29 2014: Flat Roof Leaks. There are multiple large leak problems on this commercial tar and gravel flat roof that are currently being managed with buckets. Flat Roof Ponding. The roof assembly is carrying considerable ponding all over that is definitely a concern with dead weight load on the roof in times of sudden storms or in winter freeze thaw situations. Roof Drains. There are two drains on the roof that are useless; the previous contractors did not sump them properly. Roof Maintenance. Previous roof maintenance contractors did not remove the gravel before using tar to patch spots that needed repair. An excessive amount of tar has also allowed trapped air to cause blistering. Gum Boxes. Four gum boxes were actually near open water, and it was able to get into them. This is also contributing to some of the leaks. Roof Membrane. The tar and gravel roof membrane has become weather cracked from the sun, contributed by an improper ballast spread. If the pea gravel is not covering the bitumen layers the UV of the sun will dry out the bitumen causing it to crack and ultimately leak. Blisters. There is mass blistering of the roof membrane in multiple areas. If they continue, water will enter there as well. Several of the blisters on the roof are cratering water into them. Temporary Flat Roof Repairs. While we were on-site, we attempted to drain as much water as possible. The client called off the temporary repairs since the problems have become greater than simple roof maintenance work. The client has requested a quotation on roof replacement or recovery options.

Photo Journal: TPO Flat Roof Recovery and Sloped Insulation in High Level, AB

Below you will find a photo journal from a commercial contract in High Level, Alberta. The work entailed a TPO flat roof recovery and sloped insulation. Background When a roof reaches the end of its life, our clients are faced with the choice of either a full replacement or a recovery. Roof recovery refers to applying a new system over an existing one when the roof is reaching its end-of-life (1). Depending on climate conditions, preference, or preexisting solutions, a roof recovery may be performed using TPO, EPDM, bitumen, cap-sheets and/or asphalt. Sloped insulation refers to the tapering that exists on an insulation system. As a weatherproofing measure, when precipitation reaches your roof, it will run off into the drain system down the slope. Call us today for a consult on which roof recovery system is right for your commercial, industrial, or residential environment. < End Journal > Code: HIGH Article Topics: TPO Flat Roof High Level Alberta.

Roof Leak Repair in Edmonton AB, December 2014 and July 2015

Below you will find an assessment and field report from the Edmonton roof leak repair crew for a residential client. The roof had been experiencing leaks on two occasions due to a lack of proper ventilation and insulation. Assessment, December 12 2014: By the time we had arrived, the leaking had stopped. However, our client still had buckets out in her kitchen for water collection. The client also showed me the garage, where there appeared to be water damaged on the ceiling. Again, no evident leaking at the time of assessment. A roof inspection was also completed, and we found 4 in. of ice damming.

  Installation, July 20 2015: When I arrived on-site, the client showed me two leaks. One was in the living room and another in a bedroom. Both leaks were in line with each other. On the roof, a crack running half the length of the roof was found - the same cracked that was fixed the year before. The crack had probably reoccurred due to a lack of insulation and venting. We fixed the crack again with LR and the client was notified about the insulation and ventilation.

Nisku Liquid Rubber Roof Recovery, August 2011

The report below follows services carried out on a metal roof for one of our industrial clients. They sought GRS' assistance in recovering their roof with engineered liquid rubber, with some other spot repairs to complete as needed. Inspection: June 2, 2011 The GRS crew went on location to inspect the existing roof system and take photos that will help the project management group form a better idea of what service will be needed at this location. The photos appear below.
100_0006
Our client had an industrial-grade metal roof. A crew was dispatched to perform an initial inspection with regard to the scope and requirements of performing a roof recovery using engineered liquid rubber.
100_0008
Many of the screws were exposed or missing, with parts of the metal beginning to rust.
100_0009
Rusting at the seams, with exposed screws running the length of this section of the roof.
100_0010
There were signs of previous spot repairs. In this case, caulking had been applied to the screws.
100_0011
More spot repairs, with caulking applied at the seams and over the edges. This solution had expired, with cracks forming along the length of the roof where the caulking had been applied over the seams.
100_0012
Closeup of some old sealant applied over seams and around raised screws. Note the hole in the fastener that had previously been closed off. As well, there are slight buckles in the metal. Each of these deficiencies contribute to common leak entry points and a loss of a metal roof's water shedding properties.
100_0013
We inspected the wall connection, noting whether any components on the wall itself needed to be replaced, and whether we had to order any new flashing as part of the recovery.
100_0016
Sealant had previously been applied to the window sills, flashing, along the wall seams, as well as on the intersection between the flashing and the standing seams on the roof. Besides showing signs of cracking, there was also more rusting along the walls.
100_0017
Significant rusting on the flashing, with an unsealed base for the rooftop appliance. As well, the edging over the window sills is not flush with each segment. Further down, it can be seen to be curling up from the window.
  Quotation Delivered: June 6, 2011 After seeing the roofers' investigation photos and measurements, GRS' project management could deliver an accurate quotation for services to be carried out of the roof. Included in the quotation were two separate services; the engineered liquid rubber application and an EPDM installation for the area around two eaves. Also attached to the quotation were the documents and web links surrounding GRS' workmanship guarantee, system methods, schedule availability for the season, and more. There was another note mentioned that regarding schedule availability, it's best to book liquid rubber jobs earlier in the season for when it's warmer. Even though the solution will bond, it performs best when applied in warmer weather.   Roof Report: July 20, 2011 The crew went out to the client's building and got to administering trowel-grade liquid rubber to all penetrations, joints, and problematic areas that has been previously discovered. They also did a lap around the perimeter, ensuring watertightness on the high-risk parts of the roof. They then set up the pump to apply the spray-on liquid rubber and managed to cover roughly one-quarter of the roof itself. Their plan was to finish the entirety of the roof the following day, so they packed up the equipment, cleaned the site, and closed the site for the evening.

By the end of the day, our technicians managed to coat one-quarter of the entire roof.
    Site Inspection: August 1, 2011   One of the senior members of GRS' crew went on-site to inspect the liquid rubber application and found it to be forming a good seal. There was some water that had formed a small bubble in the rubber, but once popped it was deemed fit for continued use as the rubber still formed a solid barrier to the metal.   Roof Report: November 25, 2011 Several months after the initial liquid rubber coating, the client call in to report some other leaks in separate areas of the roof. GRS sent a team out to the site to investigate and carry out the necessary repairs. They administered sealant to the flashing where the wall meets the north-facing roof edge, and again on the south-west corner of the building. They also sealed in the wall-to-roof spots on the west-facing wall and inspected the existing wall spray. After carrying out the spot repairs, they had a better idea of what else needed to be done to the roofing system, and returned the following report:
  • The west-facing wall where the windows are is 3' x 78'. Will need 100' x 6" skrim sheet, and roughly 16 man-hours to install it.
  • The north-facing wall is 3' x 40'. Need 50' x 6" skrim sheet for another 12 man-hours to install.
  • The west-facing wall's upper roof is 3' x 24'. Need 25'x6" skrim sheet and 10 man-hours to finish.
The site was cleaned up, and the crew departed, leaving the repair options in the hands of the client.   This report will be updated as more reports come in, should the client elect to move forward with repairs.
