Edmonton Roof Investigation, August 2013

GRS sent out one of our technicians to inspect and investigate the causes for a wide number of problems found on this client's split-level roofing system. The roof itself is nigh-irrepairable, and we recommended an entire roof replacement.   Investigation: August 9, 2013 GRS sent out a technician to perform an investigation on the roof's overall state. The roof itself is broken into two sections; the lower being a tar and gravel system measuring 25' x 27', and the upper as a granulated rolled roof measuring 53' x 52'. There are also several penetration to the roof system, with twelve standard plastic roof vents, six skylights (7'6" x 7'6"), and four 'whirlybird' vents. The investigating technician found the roof to be in a very poorly state, and that the roof deck is hazardous to walk on as there are numerous soft spots to be wary of. Some of it has been resurfaced with TPO, Torch-on, Sopramastic, and/or rubber (EPDM), but these are patches that don't constitute a full repair. The upper section's overhang is also currently propped up with deteriorating wooden blocks, which much be replaced. When the technician went to the lower roof, they noted that the tar and gravel system was also due for replacement, with blisters coming through and some 'bald spots' where the gravel is no longer sticking to the tar. The final opinion of the GRS crewmate that carried out the inspection is that the roof itself cannot be repaired further, and that an entire replacement is mandatory to address all of the issues that presented themselves.     Regrettably, the photos from this investigative report are no longer available.

Tile Roof Inspection, April 2013, Edmonton

This client reached out to GRS for work on their multi-home building's roof. It is a tile system, with several reports of water ingress and expected damage to the roof itself. GRS sent out a technician to investigate the problems. Unfortunately, photos of the roof taken during inspection are no longer available. The placeholder image above simply provides context to the roofing system style.   Quotation Delivered: April 3, 2013 GRS delivered a quotation to the client covering the services they'd requested. The scope of the work, as outlined in the document, was to remove the tile, check the underlying membrane and valleys, carry out any repairs, then reset the tile system back on top. Before scheduling the work, however, we felt that it would be best to send an inspector out to investigate the problem areas to ensure that the quotation would be fair to both parties in the arrangement.   Inspection: April 22, 2013 The inspection crew went on-site to examine the extent of reported damages. For four of the suites in the building, they checked the roof above and found some major damages that required repair. Near the first suite, there was a major hole in the firewall where both sides of the lead wall's flashing were bent and folded back. The extent of the damage was allowing water to run in behind the flashing and through the hole, spreading down to the suites below as far as the first floor. There was also a piece of wall flashing missing on the front of the turret in the same section, with potential leaks on either side of the chimney in the area. The chimney itself was missing a proper installation and application of ice and water membrane/shield installed around it. Across from these affected areas, on the back of the building, there were several cracked and/or missing tiles in the valley, exposing the roof deck to water and snow that had allowed water ingress to the suite below. In this section of the roof, all of the tiles would need to be removed and the ice and water membrane installed underneath so as to prevent further leaking. Then, with the tiles put back in place, the missing/cracked ones will need to be outright replaced with new ones. Above yet another unit (on the northern corner of the building) there is a long valley that might be overflowing its metal flashing sidewalls and into the attic. Above this valley is a set of short, attaching valleys that separate at 6/12 grade roof from a 4/12; creating a 2/12 grade roof in the middle. On this last 2/12 roof section a great deal of snow could/would pile up during the winter, creating ice dams that allow for a backup of water. These problematic valleys should have the ice shield material on either side of the metal to help keep water in the valley itself. When the crew first attended the site to investigate problem areas and leaks, there were only three that they knew to be coming in. While atop the roof, however, they found that there was no ice and water membrane used alongside any of the roof valleys (not just the ones noted above). Given their absence, it's possible that any and all of the valleys could become future candidates for leaks or further roof damages, especially when any of the surrounding tiles are cracked or otherwise broken/misplaced. The investigative team advised that the roof be cleaned off of leaves and debris, which would allow for a thorough accounting of all of the tiles and the existing system. Rubber-modified sopramastic should be applied to all cracked tiles around the roof to prevent further leakage, and the side cap tiles should be refastened in any places where the nails seem loose or missing.   This post will be updated with roof reports should the client elect to contract GRS to carry out the required work.   CODE: 6703 Contact Us Call our 24 hour emergency roof repair at 1.780.424.7663.

Devon Flat Roof and Vent Repair, April 2012

This multi-family housing unit in Devon, Alberta required repair service as water was leaking into one of the tenants units. Our crew was dispatched to complete the work which included vent repair. Inspection, April 15, 2012: 
Conducted inspection as best I could as my ladder was not sufficient. The client simply wants a leaking exhaust vent removed and to have the opening sealed. The vent is approximately 4 x 4. We will require a 30 foot ladder to get to the roof. There is access to a lower level via stairs and a door, however I would not advise carrying a ladder up there as we would have to go through an aroma therapy clinic which is quite tight. The client would like to move ahead with this ASAP, so we just require a quote. The front of the building is quite tight as it is located on main street, however the rear will accommodate equipment and trucks quite well.

Roof Report, April 17, 2012: We removed the exhaust vent from the roof and then made a recess for the flared hatch. This was so that we could install plywood over the open hole.
We then cleaned, prepped, and re-insulated the hole before covering it with liquid rubber.

Shake Roof Inspection, September 2011, Edmonton

This brief report outlines GRS' contact with a client that has an aging cedar shake roof that is in need of replacement. GRS sent out a technician to inspect the site and take measurements to see exactly what kind of shape the roof is in, and how much material will be needed to carry out the service.
