St. Albert Commercial Roof Warranty Repair, May 2015

This report details a warranty dispatch for a liquid rubber installation which had been done the previous year. There was some leaking from the penetrations which needed to be addressed. Also included is the quotation for the original liquid rubber install. This project began in 2014 with a liquid rubber install on a commercial unit. The following are notes from our project manager concerning the initial state of the building pre-install:
This roof structure is a candidate for either a repair-maintenance program or a restorative engineered coating and may not have to be replaced. I would not recommend a standard reflective elastomeric coating or the SPF Spray Foam specifically with a standard reflective coating as the industry wide standard reflective coatings do not last well over time in our Western Canadian climate. This recommendation would possibly change if your objective is to reflect the sun, in this instance a reflective coating may be best, but in Western Canada the issue tends to be during winter months with metal roofs. Liquid rubber performs well in our climate as it has up to 1200% expansion and contraction. If considering Spray Foam for R Value we strongly suggest covering the spray foam with liquid rubber or preferably EPDM and not a reflective coating or white coating. Generally speaking, metal roof systems are constant aggravating roof structures. Industrial metal roof systems have a deficient design - they are water-shedding and not water-proofing coverings. Metal expands and contracts more than any other roofing material. Metal roofs tend to leak from expansion and contraction and ice / snow loads. Leaks are intermittent at seams (vertically where sheets are seamed together and horizontally where seams between sheets meet), penetrations (stacks, roof-top unit curbs, etc.), fasteners (fastener holes get larger with expansion and contraction), around the perimeter as ice back-ups at gutters and then under eave (hidden and external gutters have the same ice back up melt issue causing leaks), and at joints between roof and wall connections. Metal rust / corrosion may start at places, the seams and fasteners are vulnerable from expansion / contraction and snow loads, and any traditional caulking or reflective coating won’t last more than a few seasons at best. Remedies to the issue are; 1. Complete replacement of the metal roof which is most expensive and may leak anyway, 2. Spray-Foam (SPF) applied to metal with a top applied membrane - reflective coating, liquid rubber, or EPDM, which can be problematic as the metal, foam, and top coat expand and contract at different rates and reflective top coats tend to fail easily in our cold climate, 3. A roof board mechanically fastened on top of metal panels with SBS Torch-on or EPDM membrane which was a typical solution in the industry prior to liquid rubber coming to market – it is comparatively expensive and expansion and contraction again can be an issue, 4. Spot repairs-maintenance with caulking per scope in quote above, and 5. More extensive restoration which involves engineered coatings. Our recommendation is option 5 - a high end engineered liquid rubber polymer coating that carries a 10 Year Manufacturer Warranty and has option to a twenty year GRS maintenance contract for extended leak protection. In this instance, we recommend a 2 Ply Engineered Liquid Rubber Recovery System to the complete metal roofing area. This can be even more successful than a full metal roof replacement (depending on objectives). A recent project with photos can be found at; http://generalroofingsystemscanadainc.blogspot.ca/2012/05/roof-repair-liquid-rubber-metal-roof.html The scope of work involved in a metal roof liquid rubber recovery coating is; 2 Ply Engineered Liquid Rubber Recovery to Complete Metal Roof. Pressure wash to clean, water test, and assess. Test and replace fasteners as required to complete roof deck, penetrations, and gutters. Sheet metal repair and penetration saddle fabrication as required. Remove old caulking as required. Hand trowel all penetrations, roof to wall connections, all fasteners, ridge, horizontal sheet seams, hidden gutters (if present), and roof edge at external gutters with mesh and high grade rubber as required. Apply liquid rubber coating, allow cure time, repeat hand trowel process above, and apply second coat liquid rubber. The Ten Year Manufacturer Warranty is Extendable to Twenty Year Service under GRS Maintenance Agreement. Thank you.
Original condition of the roof: 1 2 3 4 5 6 7 8 9 10 Subsequent to the liquid rubber installation, the client later contacted us to report some leaking around the penetrations on the roof. The work was still under warranty and the client was informed that a crew would be dispatched to make the necessary repairs. The client was made aware of the fact that metal roofs are prone to expansion and contraction (depending on the season), which often leads to leaks. He was also assured that we would be applying additional liquid rubber to the leaking areas until all leaking had stopped. Once on site the crew inspected the roof and determined that it was very likely penetration leaks. Dampness was observed on the interior ceiling and walls. On the second floor the leaks were mainly coming from the skylights, however there was one leak from a ventilation penetration. The source of the leak on top of the roof was not visible and so could have been a pin hole leak. The leaks were not serious in nature except for the office skylight which was significant. 20140115_125536 20140115_125658 20140115_125826 20140115_125850 20140115_125907 20140115_130304 20140115_130317 20140115_130351 20140115_130406 20140115_130411 20140115_130727 20140115_130800 At this point our project manager instructed a crew member to track the leak over the course of a few warm days. The warmer weather was required to fully understand where the leak was coming from. This was completed and additional liquid rubber was applied to the metal roof in order to prevent further leaking. 20150505_103645 20150505_105545 20150505_105559 20150505_110456 20150505_111056 20150505_111122 20150505_112400 < End Report > CODE: 23 Contact Us Call our 24 hour emergency roof repair at 1.780.424.7663.

Edmonton Commercial Flat Roof Replacement, January 2015

This commercial client in Edmonton was presented with a quotation for a flat roof replacement. The report follows the crew as they performed the replacement over the course of several months. Scope of Work:
  • Scrape gravel down to existing 4 ply membrane and take down to dispose.
  • Supply and glue down a FR board (1/2 inch fiberboard adhered to a 95 gram sanded poly sheet) and seal all laps.
  • Supply and back torch a 180 gram armour bound peal and stick up walls and all penetrations.
  • Remove and replace any wet insulation.
  • Owners to move and re-position satellite and communication systems.
  • Clean all debris and haul away.
Roof Report, January 21, 2015:
We arrived on site at 2:10 pm and I got set up to continue with the cap stripping. At the same time we were waiting to see what was going to happen with the weather since it was still drizzling. I went through the safety paperwork and then we helped with removing the garbage from the roof and brought it to the bin. 20141212_14051920141212_195820 20141212_195807 20141212_140503 Roof Report, January 23, 2015: After our toolbox meeting we proceeded to install FR board on the upper mechanical roof and did so until the point of satellites in all directions. We then installed peel and stick stripping wherever possible and sopramastic waterproofing in all other protrusions.
Cleaned up and left site at 4:30pm.

Roof Report, February 12, 2015:
This morning after we were done with the safety reports, we went to the upper roof and continued with the base seal tie in. I had two other crew members remove snow from the entire upper roof while I started to install peel and stick on the curbs. After I was done with the curbs on the north side of the roof, I installed patches over the plates and installed gussets were there were none. I also found several spots that needed patches in the field and repaired as required.
Roof Report, February 14, 2015:
Started to lay in FR board where they moved the satellite towers. Once we got the base done on one I had a crew member start capping it in while myself and another crew member started to base in the next section. Both sections were capped by the end of the day which made the client happy. Then I stayed on site to complete fire watch.

Roof Report, February 18, 2015:
This morning we started on completing the NE corner of the roof by installing the last of the FR board. We also started sealing around the curbs and perimeter.
We then moved to the SW corner and completed the base tie in around the satellite and patched plate holes in the area. Fire watch from 3:30pm to 5:30pm.

Roof Report, February 19, 2013: Once we got to the site we continued with the base tie in around the large curb and the parapet on the SW corner of the upper roof.
Roof Report, March 7, 2015: Today we completed the field cap and most of the DE granulating around the details. Roof Report, March 9, 2015:
Bill and me completed the cap stripping on the upper roof today and need to touch up the gum boxes and granules to finish the SBS on the upper roof. We then completed the curbs on the main roof and started to install the plumbing vents when it started to rain at 3 pm. I am not happy with the large ponding area on the east side of the main roof and would like permission to extend the sump on the east side with a trough through the high spot so that more water drains.  I would have to cut out the FR board from the sump about 1 ft. wide west about 10 ft. to where the water ponds 3 inches at the deepest point. Then tie in the old roof to new torch on roof through the trough. This would require 10 man hours and another roll of cap which would add another 2 years to the life of the cap in that area. Roof Report, March 10, 2015:
Today we installed 8 plumbing vents and touched up the existing plumbing vents with smag and granules. We completed the west drop drain install and reset the air units on the SW corner of the main roof. We then cleaned the entire main roof and downloaded all the garbage. Roof Report, March 11, 2015:
This morning we completed the touch ups on the gum boxes of the upper roof and then started installing the metal around the perimeter of the upper roof and found that we were short one length. On the far east side of the roof there looks to be another piece missing that would cover the electrical lines and 2-18 inch storm collars are gone as well. We installed all the metal that was there and added extra screws and smack pins to make them very solid.
Roof Report, March 12, 2015: After the weekly meeting in the morning we met up at Home Depot for caulking and then went to the site. We spent extra time on resetting all the wire tracks on the upper roof and finished off the storm collars with caulking as well. 2 of the 18 inch stacks still have no storm collars but we filled them with caulking anyway. With no metal flashing on the wall detail on the upper roof, we made sure that water would not pond there by completely filling the riglet with caulking. We downloaded the rest of the tools, rolls of base, and propane into the small trailer and parked it in the very NE corner of the parking lot.  The bin is still on site and will need to be removed.
Follow-up Inspection, August 19, 2015: Upon visual inspection of the roof. I noticed 6 different blisters had developed. Attached is a copy of a roof map that shows the approximate locations of the blisters. Continuing on we walked the entire roof, testing the membrane to make sure the insulation was properly adhered to the roof underneath. I would say that there is no issues with the adhesion. The following is a list of the repairs that should be made to said deficiencies:
  • A lack of chipping away at the existing roof that was re-roofed led to a ridge. We can either build it up around it, leveling it off, or cut it and patch it.
  • Run a patch to meet lapping requirements.
  • Pipes need to be patched.
  • Anchor fasten the flashing correctly to the wall. Ms detail to seal the flashing.
  • Replace with concrete paving stones and roof mate underneath, and have a drainage mat under the roof mate.
  • Run a drainage mat or roof mate.
  • Install storm collars and caulk them.
  • Have a flashing made up and installed.
  • Have a sheet metal cap fabricated and installed.
  • Install cap sheet, roof mate, drainage mat and paving stones.
  • Box it in with cap and quick prime.

Edmonton Industrial Liquid Rubber Roof Recovery, August 2014

This is the second part of a project for this industrial client in Edmonton. A full liquid rubber roof recovery was requested for this part of the project. The previous article detailing a downspout installation can be found here. Roof Report, August 22, 2014: We installed all of the units except for one and all of the penetrations are done on the shop roof (18 units and about 50 penetrations). All units were meshed and sealed with liquid rubber. Tomorrow we will get all the seams completed which is about 2100 ft. 20140822_104304_resized 20140822_104330_resized 20140822_104356_resized 20140822_110144_resized 20140822_110148_resized 20140822_145401_resized 20140822_145440_resized 20140822_150127_resized 20140822_152747_resized 20140822_161413_resized 20140822_161436_resized 20140822_161449_resized_1 20140822_161516_resized 20140822_161528_resized 20140822_165934_resized 20140822_165941_resized 20140822_170016_resized 20140822_170304_resized 20140823_115436_resized 20140823_133815_resized 20140823_170902_resized 20140823_170927_resized 20140823_170929_resized 20140823_170944_resized 20140823_171038_resized 20140823_171118_resized 20140823_171123_resized 20140823_171134_resized 20140823_171151_resized 20140823_171234_resized 20140823_171418_resized Roof Report, August 23, 2014: Today we got most of the seams done on the shop roof.

Edmonton Residential Flat Roof Inspection and Repair, October 2013

The report follows a repair on a residential rooftop that is in fairly good condition. No leaking is present however there are issues with the penetrations on the roof as well as the flashing and vents. The home owner requires an inspection of the roof to pass and therefore needs the repairs completed immediately. Roof Observation Report: With respect to the request to observe the roof assembly at said location, the following are noted: The roof overall is in fair to good condition and looks to be approximately 10 – 15 years old. No leaks identified. No soft spots observed. There are however deficiencies with the penetrations on the roof. It appears as though the roofers installed the roof penetrations without a proper tie into the BUR and just graveled over the flanges. Hence, the lead flashing on the plumbing vent(s) is slowly sliding down hill and bending. Additionally, there is some minor damage at the front end of the house were the felt has been exposed to the sun and has dried due to UV and separated from the house. This will lead to leaks if not repaired. At the back of the house, there are some sun dried spots due to UV along the gable drip edge but this will not be an issue for another 1 - 2 years approximately. The roof definitely requires one plumping vent replaced and a small area of gum and jewt in the front of the house to pass inspection. The other vents are going to cause problems within the next 5 years or sooner. I would need approximately 16 – 24 man hrs. to replace the one plumbing vent and remove some flashing at the front of the house which would bring this roof to a “pass” condition. However additional time is required to properly install all penetrations (approximately an extra 32 - 38 man hours). 1 2 3 4 5 6 The crew arrived on site to begin repairs on the roof. The lead flange for the plumbing stack (completely cracked) was fixed. Next they spudded the field and installed a high top. Finally it was gummed and then poly was applied on top. Gravel was added for the finish. Materials Used:
  • 1x roll of Jewt (sopralastic reinforcement).
  • High Dome Flashing for 4" Vent.

Edmonton Residential Roof Leak Repair, March 2011

This report outlines a relatively small repair on a residential roof that had been leaking water. The eight penetration vents and stacks on the roof were not installed properly and needed to be attended to. An estimate was sent by our project manager and subsequently approved by the client. Following that, the crew headed to the site to perform the repairs. The crew had to lift the surrounding shingles from each penetration and re-seal in order to waterproof. The shingles then needed to be placed back in their original positions. From start to finish the repairs only took about 4 hours time.
