I had the labourers remove snow from the entire upper roof while I started to install peal and stick to the roofing 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 was none. I also found several spots that needed patches in the field and repaired as required.

  March 12, 2015: Crew comes back to complete final touches on roof. Roofing recovery completed. We spent extra time on resetting all the wire tracks on the upper roof and finished off the storm collars with caulking as well.  Two of the 18 inch stacks still have no storm collars but we filled with caulking any way.   With no metal flashing on the wall detail on the upper roof, we made sure that water would not pond there and completely filled the ringlet with caulking and should hold. At the end of the day we downloaded the rest of the tools and but 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 needs to be removed.

Commercial Roof Recovery for Existing Client in Edmonton AB, April to June 2015

Below you will find a series of quotations for an existing commercial client. We had previously dealt with some leaks for them as outlined here. This time, the client required a roof recovery for a 28 ft. x 44 ft. garage. Client files request, April 20 2015:
I know that you quoted on the small garage, we would like another quote that requires the following: layout, retrofit, TPO roof, no asphalt.
Quotation, April 20 2015:
  • Layover, remove stone.
  • Install new 2 in. polyisocyanurate and 0.45 mm TPO membrane.
  • New flashing is required all around to match the front of the building.
Assessment, June 22 2015: We arrived at 8:00 am and searched for roof leaks around the unit for two hours. With no luck, there was still the remaining task of installing the last drain unit over another one of the units which needed work. The roof on the second building is a 28 ft. x 44 ft. BUR roof on a wood deck that leaks in too many places to fix. One drain on the northwest corner and three other penetrations, as well as two vents and a motor exhaust are going through the roof. There is a 4 in. wood detail around the edge and one scupper. We suggest an EPDM roof recovery. The maintenance manager for the site also gave us a call to tell us that a leak was found on the west wall of the building. The crew found numerous rips in the roof along the membrane; it had been completely separated from the drain.

Materials:

  • 5 ft. of cap
  • 5 ft. of base
  • 1x can of spray primer
  • 1x 3 in. drain
  • 1 can of mastic
  • 1x roll of 6 in. reinforcement mesh
New quotation based on assessment, June 22 2015:
  • Gum patches to three or more areas
  • Replace the drain with a new 3 in. unit
  • Roof replacement using an SBS 2 ply system
  • Estimated time: 20 hours

Tar and Gravel Flat Roof Replacement Edmonton, June 17, 2015.

Article: Tar and Gravel Flat Roof Replacement Edmonton to Residential Flat Roof.

Below is a brief roof site report from our Edmonton Flat Roofing Replacement crew. It is a residential roof with a tar and gravel roof that has failed. The crew will be installing a new 2 Ply SBS roofing membrane.  May 29, 2014: Crew Arrives on Site to Remove Gravel.  The gravel is all scraped in piles. Material is loaded on roof as you can see from the pictures. This roof has bad ponding issues there's only one 4 inch drain on the entire roof and of course the ponding is nowhere near the drain.

  June 4, 2014: Crew Arrives back on Site.  Today the rain prevented us from tearing off a larger selection than what we did. Another crew came over from their site to help us. They couldn't tear off unless he was going to tear it all off so he came to help us because I can easily seal off what we do on to the existing tar and gravel. We got a 25×25 ft section ripped , covered and sealed up before the rain came. Sky opened up around 4:00 and it has been pouring ever since June 8, 2014: Crew Arrives Back on Site After Rain Had Stopped.  Finished up the last of the plate/screw patches.

Temporary Flat Roof Repair Edmonton, June 15, 2015

Article: Temporary Flat Roof Repair. 2 Ply SBS Modified Bitumen Torch-On Roof.

Below is a short roof report that shows temporary emergency roof repairs using mastic to a flat roof in Edmonton, Alberta on a 2-Ply Mod Bit Torch-On System. Normally when we attend to flat roof repairs, the goal is to either perform repairs that have a high probability of lasting for some time or replace the roof. In some instances, our customers do not have it in the budget to either do the repairs properly or replace the roof. Often they have a replacement budgeted for the future. In the instance below the customer wanted the least expensive option to simply stop the leaks until he/she could finance a roof replacement. A quote for much more extensive repairs was provided but declined. January 20, 2015: Crew Arrives On-Site To Complete Repairs.  Originally the client had one leak on a goose neck vent. After further investigation it seams that another has started in a dryer vent. The crew fixed both the leaks with sopramastic and mesh. The customer looked at our work and was very happy with what was done. Man hours: 3 total. Materials:
  • 1 gal can of mastic.
  • 8 ft. of 6 inch mesh.

Flat Roof Repair Edmonton – Gum Box. June 10, 2015.

Article: 2 Ply SBS Torch-On Low Slope Roof "Gum Box" Repair on Commercial Roof in Edmonton Alberta.

"Plastic pan - also called pitch pan, pitch pocket, gum box, these comprise a flanged collar placed around items that project through the roof system; the flange is properly set into the roof membrane and the pan is well filled with plastic cement; these pans are a constant source of trouble and should only be used when no other solution can be found." Source: Red Seal Roofer Program Website. February 13, 2015: Journeyman Roofer Attends for Roof Inspection.  Address 11754 170 Street Edmonton, Alberta.
The client is experiencing a small leak 15 feet in front of the front doors around an electrical conduit penetration in the roof.
The electrical conduit is two feet from the roof edge which is the highest point on the roof as the drains are in the center. I believe the leak could be leaking around the gum box which is starting to crack or where the stack is fastened to the roof. I believe the water is getting in through those holes and running back into the system.
To fix this problem we would need to first put a gum patch on the gum box and tighten up the bolts on the bracket that holds the conduit and seal around it with some good caulking.
Man hours 3 - 6 total with drive time and inspection time. Material 1 - 3 gal pail of gum. 2 tubes of tremco chalking.
Roof measurements 130 ft x 160 ft with two drain and 13 penetrations. The roof is approximately 10 years old and in good shape.

  February 21, 2015: Crew Arrives On Site To Complete Repairs. This morning we stopped by to confirm were the problem area was and that we had everything for the job.
Once we got back to site and went up to the roof I could tell that the water was coming in from the gum box.  A couple of things caused the failure, first that the steel pipe had moved slightly from being pulled by the weight of the wire hanging and that the crew that installed the roof only filled the gum box up 1/4 of the top with gum and had 3 inches of bat insulation filler.  Over time the gum began to dry and crack and settle allowing water to pond inside the gum box and leak through.
So we removed the gum out of the gum box and some of the insulation and filled 3/4 of the gum box with pour-able sealer, a permanent repair for the problem.  As a precaution, we also added a bead of lap sealant around the base of the gum box so that no water could pond there and installed a bead of high quality caulking around the metal support which had bolts going right through the parapet wall with no sealer.
Materials used: I tube of tremco caulking. 1 tube of lap sealant. 1 package of pour-able sealer.

Flat Roof Replacement Edmonton. June 10, 2015.

Article: SBS Modified Bitumen Torch-On Residential Flat Roof Replacement Edmonton, Alberta.

We pride ourselves in quality residential and commercial flat roof repair and replacement. Having quality journeyman roofers ensures our work is always top quality. The  following installation report is a SBS Modified Bitumen Torch-On Residential Flat Roof Replacement in Edmonton, Alberta. May 14, 2015: Flat Roof Crew Arrives to Start Re-Roof. 7:30 am arrive on site. We started the day with our tool box meetings. We then set up ladder and brought all tools needed for job up to roof. We started removing the metal flashing from perimeter of roof. We also began shoveling gravel in to rows. Once all the gravel was off the roof, we then started to rip up the old roof. Once we had the old roof half ripped up the trailer was full so we did a dump run. We also stopped at Home Depot to pick up some 5/8 plywood for re-sheathing. Once back on site we filled the trailer again and then swept the roof. We had to re-sheath two areas; one on the east side of roof and one on the south side of the roof. Both were 4 ft x 8 ft sections, so 64 sq. ft. total. Once we had that done, we then layered in our fiber board (FR board). We  mechanically fastened the FR board to the roof using screws and plates. I then started torching while the other guys continued to screw in plates and start peal and stick on the perimeter. We managed to get the base sheet done 95%. There is just one small section left to torch (of the base sheet portion).

  May 8, 2015: Crew attends for day two of flat roof replacement. We got to site and finished torching in the base. Once the base was complete we had to take off the 2 bottom rows of siding because the coating on the back of it was highly flammable. Once it was off, we also had to use peal and stick to seal of the siding so no flames would enter in behind. After this was done we started capping. By the end of the day we got 80% of the field capped. By late afternoon the wind was too strong and kept blowing out torch so we left site at 5 pm.

Once all the stripping was complete, we started our fire watch. We also put all the metal and siding back on. Site is now 100% complete and customer is happy with the work we did.

Roof Deck Drainage and Waterproofing

ARTICLE:  Roof Deck Drainage Problems. Waterproofing a 2 Ply SBS Modified Bitumen Roof Balcony in Edmonton, Alberta.

Recommendations for Waterproofing Outdoor Decks Over Conditioned Living Space. Roof Deck Drainage and Waterproofing - Inspection and Repair of a Torch-On Flat Roof on Outdoor Balcony at Multi-Family Condominium. Customers regularly call on us to have roof assessments (inspections) completed. During a roof assessment our journeyman roofers assess the roofs condition. We assess the roof for preventative maintenance reasons as well as inspecting existing problems that the customer is pointing out. We then discuss different scopes of work fix the problems as well as potential materials and costs related to the repairs. One of the most common calls we get for inspections and repairs are rooftop decks, balconies and patios. The primary reason the failure rate on rooftop decks is so high is because of the original installation. It is common for incorrect membrane choice to be the reason. In other words, many people install an outdoor deck membrane that is intended only for an outdoor deck and not a membrane for over a heated living space. If your rooftop deck or balcony is over a heated living area you require a special membrane that is also intended for low slope roofing (as well as deck waterproofing) and is approved for use over a conditioned living space. Common products for this are Dura-Deck or DecTec, both of which are a PVC membrane that are suitable to be walked on (so they do not require a floating deck over top) and they manufacture membranes suitable for over a conditioned living space. We use DecTec extensively and have had great results with it. Or, also common is the installation of a membrane that won't hold up to the foot traffic associated with outdoor living areas. Other reasons include simple age, wear and tear, drainage and issues relating to penetrations or floating deck assemblies on top of the membrane. Visit our main website for more information on rooftop deck waterproofing. This particular inspection and subsequent repairs was more focused toward an aging membrane and the associated repairs that come with not properly maintaining the deck membrane and building envelope over the years. The drainage problems were causing significant damage to the exterior of the building. Below you will find the inspection report. May 20, 2015: Journeyman Superintendent Attends for Balcony Inspection. Roof Inspection Location: 10245 116 Street NW Edmonton Alberta. Roof Inspection Date: May 20, 2015. Roof Type: SBS 2 Ply Modified Bitumen Torch-On Membrane on Roof Balcony. Site Location Type: Multi-Family Condominium.

This customer is experiencing a problem with water getting in the roof system and it draining out on a low corner and destroying some exterior brick work. In the area of the leak there are 2 laps of the SBS modified bitumen that have come apart.

Torch-On Roof Replacement High Level, June 4 2015.

Article: 2-Ply SBS Modified Torch-On Roof Replacement High Level, Alberta. Low Slope Commercial.

Torch-On Roof Replacement. 2-Ply SBS Modified Low Slope Commercial Roof. SBS modified torch-on roofing is one of the more widely used flat roof membranes in Alberta. I don't know the industry wide percentages, but I would venture to guess that we install about 30% of our roofs with torch-on. EPDM would be about 45% and the other 25% would be a mix of the other types listed below. When replacing a flat roof your primary options are traditional tar and gravel, 2 ply torch-on, single ply membrane (TPO, PVC, or EPDM), spray foam (SPF) or some form of fluid applied. Visit our local Edmonton roofing division website for a more detailed description of the various flat roofing membrane options. For torch-on, common application methods are conventional roof systems and inverted roof systems. In the manufacturing process modifiers are added to standard roofing asphalt to replace plasticizers removed during a distillation process. Bitumen is then reinforced with fiberglass or polyester fiber matting in order to increase durability and strength. SBS (styrene-butadiene-styrene) increases the flexibility of the membrane and allows it to have stronger expansion and contraction capabilities - the synthetic rubber additives increase flexibility of the membrane. Modified bitumen roof systems can be installed with torch, fluid applied asphalt, or cold adhesive. A typical SBS modified bitumen roof system (as in site report below) is a two-ply application applied with a torch using rolls of membrane that overlap the edge of the previous roll. In the example below the roof board (or fibre board) is what we refer to as an FR Board and it has the base sheet SBS applied to the fibre board before leaving the factory. In this instance the base sheet FR board is mechanically fastened to the roof deck with the cap sheet being torched on after. The benefits of 2-ply SBS modified roofing are:
  1. Torch-on SBS modified roofing is very durable. This is important for high traffic roof assemblies. This would include commercial or industrial roofs where there are perhaps a lot of rooftop units, satellites, communication towers and the like and various service technicians attending to the roof regularly.
  2. It is weather resistant and can handle impact that perhaps other membranes would have issue with.
  3. It is moderately easy to repair and maintain.
  4. The factory manufactured rolls make quality control easier than with tar and gravel BUR roofing.
  5. It is moderately flexible. This is important for climates such as Canada.
In Canada we recommend our customers seriously also consider EPDM vs. torch-on if the roof has next to no foot traffic. EPDM doesn't handle foot traffic as well as torch-on but is easier and much less costly to repair. Torch-on requires a contractor with open-flame insurance - open-flame insurance is costly and many contractors do not have it. So EPDM increases the service pool of applicators that you can call for repair. Torch-on also typically comes with a senior journeyman that can be more costly than a technician for EPDM. EPDM is actually simple enough for most handy types to repair as a do-it-yourself and torch-on should not be done by anyone but a senior qualified and open-flame insured roofer. Below is a brief installation report from one of our crews installing SBS on a commercial building in High-Level Alberta last winter. October 25, 2014: Crew Arrives On-Site for Pre-Installation Meeting. Crew arrives at job site in High Level at 9 am. We conducted a tool-box meeting for safety compliance. We reviewed the scope of work and the existing roof membrane. It was a roll-on mopped asphalt roof membrane that was in very poor condition.

Article: SBS Torch On Roof Repair Leduc Alberta Commercial Property

February 23, 2015. Journeyman Roofer Attends for Inspection of SBS Torch On Roof Repair Leduc, Alberta. Report Completed. Site address: 5904 50 Street Leduc AB.
There is a leak where the two roofs on this commercial property join. 30 feet from the front of the building in the area where the leak is the SBS modified torch-on cap sheet stripping is significantly cracked and losing life. There are about 3 inches of ice across the roof and 2 inches of water under the ice. To fix the roof leak we will have to clear off a section of ice and pump the water off the roof. Once the water is off the roof we then need to dry the area so repair work can be done. We then need to de-granulate a 16 foot section of stripping and torch down new SBS modified stripping to seal in the roof and repair the leak. This roof is very old and needs to be replaced asap.
Man hours to complete repairs. 18 to 20 with fire watch and drive time. 1 - 2 rolls of modified bitumen cap sheet (frost grey in color).
