ARTICLE: EPDM Membrane Re-Roof of Commercial Building Flat Roof Edmonton Alberta June 10, 2015.The following roof report is of a GRS crew completing a full re-roof on a commercial building in Edmonton Alberta. This roof was 8600 sq. ft in size. This consists of moving gravel from sections of roof. Installing a new EPDM membrane to the surface of the roof. Then covering the new EPDM membrane back up with the gravel. CREW ARRIVES FOR DAY ONE OF THE JOB. 10:00 am arrive on site. Filled out our hazard assessment form, then went up on the roof. We loaded our accessories on the roof with a rope, the main roofing materials were lifted with crane. Once it was all loaded, we started to move gravel on the right side of the roof. My original plan was to remove gravel in a 20' x 50' ft. areas on the roof. I changed my plan and just removed all the gravel from one side of the roof. That way we could just roof all weekend, rather then push gravel again tomorrow. We managed to get all the gravel from one side of the roof to the other. Now have a nice chunk to roof in over the weekend. 5:00 pm leave site. DAY ONE PHOTOS. CREW ARRIVES FOR DAY TWO OF JOB. 7:00 am arrive on site. Had our daily tool box meeting. We then got up on the roof and started to cut the old EPDM membrane out. We Then laid down the new EPDM membrane. The way the lay-out worked was we had to put separate pieces up the parapet walls on the north side. If I didn't do it this way I would of ran into trouble with all the pitch pockets. We manged to put 2000 sq. ft. in today. Most of the units we had in that area are all sealed in and form flashed on the corners. We did this with four guys. Tomorrow should go better with six. 6:30 pm leave site. DAY TWO PHOTOS. WEDNESDAY JUNE 10, 2015 CREW ARRIVES FOR DAY THREE OF JOB.
7:30 am arrive on site. Had our daily tool box meeting. Today we had a crew of six guys working on the roof. So all six of us then got up on the roof. I had two guys start doing detail work while I had two other guys start putting in pieces of EPDM membrane under the rooftop make-up air duct work. This wasn't easy because we could only do 15 feet at a time. The reason for this was we had to jack up the air duct and remove the rooftop pavers. We then had to put them back in once we got the piece lined up my work partner and I were laying the field - which is a lot of measuring and cutting to get the pieces to fit in around all the units. I had a half day on the north side of the roof which is the difficult side of the roof due to all the units and penetrations. We then will move to the south side, which will be easier side because there is very little detail work on that side of the roof. The EPDM membrane re-roof is 50% complete as of day three.
6:30 pm leave site.
DAY THREE PHOTOS.THURSDAY JUNE 11, 2015 CREW ARRIVES FOR DAY FOUR OF JOB. Today we had to finish the north section of the roof. We had to install the two last pieces of EPDM and roof in around three units. While myself and two others were doing that I had two other guys start gluing up the walls. At 2 o'clock there was a serious threat of rain so it was all hands on deck to get the exposed long lap sealed in around all the posts. We also had gum cups to do, which we managed to get done in just the nick of time. DAY FOUR PHOTOS. FRIDAY JUNE 12 CREW ARRIVES FOR DAY FIVE OF JOB.
When we arrived first thing in the morning we had to clean up some water from the rain the night before. After that I started on lap sealant where it was required and did a search of all the laps and corners to make sure they were all tight before we put all the rock back on that side of the roof. Once inspection was done we then put all the pavers back where they were before we took them out, we then filled in with gravel. Once the gravel was back in place we then turned our focus to the south side of the roof. We removed 80% of the gravel so we can start to lay EPDM down in the morning. This shouldn't take that long once the new membrane is down. I will get guys on gravel right away while others glue up the walls and start detail work.

Monday June 15th: Crew Arrives For Day Six Of Job.
Today we we cleared off the gravel on the s.w corner of the roof. The area was 20 x 110 feet. Once that was done, we swept the area off and laid out our first run of EPDM 10 x 100 ft. Once that piece was all installed I had one worker start the next run of EPDM 10 x 100 ft so he could start on the seams. I then had another worker start on the walls while I was doing the details around the drain and post. At the end we started to put the gravel back on that section of the roof so we could start the next section the next morning.
Day Six Photos.Tuesday June 16, 2015: Crew Arrives For Day Seven On Job. Today we started by moving the rest of the gravel off the SE portion of the roof so we could then lay down the last two pieces of the EPDM membrane. Once all the gravel was moved we laid in the 2 pieces of EPDM 70 ft by 10 ft. Once they were in we installed our seam tape and started our laps on the EPDM. Once the final pieces of EPDM were installed and complete I had a worker finishing the walls and I was finishing all the detail work. At the end of the day we put all the perimeter metal back on and spread all the gravel out. We then packed up all of our stuff and down loaded it off the roof to the truck and trailer.
