This industrial client reported problems with their metal roof and sought GRS' assistance in sealing all potential problem areas to prevent further water ingress. A team of six technicians went on-site and spent half a day sealing up all of the metal roof's seams. Continue reading Industrial Metal Roof Repair, April 2012, Edmonton

Roof ReportsInitial Inspection: April 17, 2012: Sealants The sealants on all 9 roof levels are deteriorated and require attention. Drainage One drain was found to have a great deal of debris blocking the way for water. It was cleared as best as possible, but is still draining slowly. Parapet Walls The EPDM roofs (of which there are 2 from the total 9) seem to be in good condition. The metal lining the parapets are also in good condition. Building Structure Building Structure Interior - Very good condition Building Structure Exterior - Very good condition Tie-Ins See 'Sealants' (above). Several of the EPDM plumbing boots, wire boots etc. are damaged. This can be seen in cases where the caulking has been worn away or when there are holes in the rubber itself. Air Conditioning Units We found that much of the flashing sealants have cuts and abrasions. There is moisture is getting through that needs to be addressed. Splitting N/A Blistering N/A Ridging N/A Fish-mouthing N/A Punctures We found punctures in the metal roofing, but did not observe any in the EPDM as it is covered with large ballast (approximately 1 to 1.5 inch gravel). The client, however, has reported many leaks in that part of the building, so openings of some sort must be present. We will need investigate further. Ballast For the most part, the ballast is adequate and well-distributed. Summary It is very difficult to pinpoint where the moisture is entering on the EPDM portions of the roof, however it appears to coming in in several areas. Several offices within the building have experienced substantial leaking. This is a very large structure and would benefit from regularly scheduled maintenance. Many of the current issues could have been mitigated before becoming a problem. Roof dimensions are:
- 55' X 112' EPDM.
- 38' X 51' EPDM.
- 60' X 51' METAL.
- 128' X 97' METAL.
- 125' X 97' METAL.
- 158' X 80' METAL.
- 77' X 25' METAL.
- 77' X 57' METAL.
- 38' X 47' METAL.
- 2 tubes ms detail.
- 1 tube of barr.
- 2 tubes lap sealant.
- 4 ft. of cover tape.
- Splice adhesive.
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.

This report summarizes an annual maintenance and repair service done to ensure a water-tight state on a complete roof system. A subsequent return was required in order to touch-up potential problem areas. The crew arrived on site and began prepping the standing water areas. Next they rolled on high build 200 (14' x 26' 364 square ft.). A crew member called the project manager to begin fire watch as a propane torch was required to make repairs. Rubberized membrane was rolled onto the affected areas which were causing water leaks. The initial repairs had been done but there was still some leaking occurring. The crew returned to the site, located a couple of areas that could be potential problems and did some touch up work. The return visit only took one hour. < End Report > CODE: 13131 Contact Us Call our 24 hour emergency roof repair at 1.780.424.7663. Mail to: 3428 99 Street NW Edmonton, Alberta T6E-5X5.

This post reflects the field reports of a GRS crew attending to a client's re-roofing request. At the onset, it would appear that they would like to explore Tough Roof or a liquid rubber system.Update (June 1st, 2012): The crew returned to the job site for ~10:00am and continued pressure washing the roof and preparing it for the spray-on liquid rubber. They departed again for 2:30, having completed the preparations. Liquid rubber was then applied to the roof in what is called a 'flood coat'. The crew cited that the single coat was appropriate, and that another wouldn't be necessary. Update (June 13, 2012): The client called us to advise that a leak had developed at the skylight and that regardless of rain quantity, it appeared 'random' in how much water would seep through, and at what rate. The leak began after the Christmas lights were removed from the screw-in fixtures atop the window capping. The responding team went back up onto the roof and determined that the caulking around the windows was correctly applied. They concluded that there was no damage to the roof or fault in the liquid rubber application; the leak must be a problem with the window itself. CODE: 4722 Contact Us 24 Hour Emergency Roof Repair.

The homeowners at this location are in the midst of a complete remodel and are looking to eliminate all problems with their roof. Though smaller repairs could be made, it looks like they would like to replace the roof outright. After explaining the systems available to them, they appear most interested in Tough Roof or a liquid rubber system.Scope of the Work:
- Sealants and tie-ins are dried, non-malleable, and cracking.
- The drainage appears to be good. No clogs, No pooling.
- The parapet walls consist of capping only.
- Building structure interior and exterior appear solid
- The current tar and gravel roof is splitting - there is no sponginess. Blistering was found in 2 areas, with the larger of the two nearly punctured.
- Christmas Light holders have been screwed into the capping above the windows, this will have to be replaced.
After picking up some equipment from another job, the crew arrived on site for 9:20am, ready to begin preparing the roof for liquid rubber application. The gravel had to be removed first, followed by a thorough power washing to remove all possible debris from the roof. This took up the bulk of the day, but they received some extra assistance between 3:30 and 5:30 from another pair of crew members after they'd completed another job. Everyone on the main team departed at 6:30pm.
