Edmonton EPDM Roof Replacement, May 2011

Below you will find a series of reports pertaining to a residential client in need of some work to their roof. They sought an EPDM installation with some retro-fitting/installation of skylights, gutters, and downpipes. After receiving our quotes for services to be tendered, the client was interested in an EPDM re-roof with some additional features to be installed during the project (skylights, gutters, downpipes). Our quote, however, assumed that insulation would need to be entirely removed and replaced, which was not the case. We re-quoted the job (with minimal insulation work) and advised the client on the warranties available for materials and workmanship. Assessment, April 29 2011:
We arrived at the client's house to assess the building and existing roof system so that we might come to a better understanding of the scope of the work to be completed. We came up with some notes, and sent them to the client for review:
1. In terms of scheduling, we are held up on a commercial site that may put us a number of days off May 2, 2011 will keep [the client] abreast. As soon as they are off the job they will be ready to begin this project - likely Wednesday or Thursday [May 2nd or 3rd].
2. The disposal bin: when the truck goes up onto the lawn and unloads/loads the bin, there could be some damage to the lawn and beds by the sidewalk. We will do what we can to alleviate, but it is of concern.
3. In terms of scope, here is what we are ordering and planning for;
House
  • Remove shingles.
  • Remove sheathing, insulation, and poly.
  • Insulators come in.
  • Re-sheet deck (we are supplying material).
  • Install EPDM system.
  • New skylights installed.
  • Edge flashing to be white.
  • Gutters and downs replaced to be white.
Garage
  • Remove shingles.
  • Reapply new green shingles.
4. We have spoken to three insulators that we normally use and will be deciding this weekend on whom we will be using; also have to speak to the fourth insulator that [the client] provided the contact information for (before making a decision). Inspection, May 11 2011: After selecting and contacting/contracting an insulator, we sent them on location to take measurements of the work area to understand how much material will need to be ordered. They were curious about the existing insulation, and whether they were to remove it or not. We put them in touch with the client to sort out the details on insulation removal. With respect to the spray foam insulation, however, the contractor advised us that they can only do the rooftop insulation in the event that weather permits and is not too windy. Roof Report, May 16 2011: Our crew loaded the metal and trim for two jobs, and drove into town to make the delivery. From 1:00-2:00pm they dropped the supplies for the first job, then made their way over to this job's site for 2:00pm and unloaded the tools and metal for the job. Roof Report, May 17 2011: The team, being yet unable to work on the roof, delivered the Ice & Water shield in addition to the tools required to work with the barrier. They left the site shortly after arrival to continue deliveries of materials to other job sites in the city. After picking up the necessary wood for this roof, they returned around 8:30pm and dropped it off; departing the site at 9:00pm. Roof Report, May 23 2011: One of the project leads met with the client to answer some questions about the job's progress. They discussed how the ridge vent is venting, and some of the desired changes to existing roof features. The client wants a guard installed on the gutter behind the house, and the eavestrough on the right side of the house raised to meet the new downpipe. The EPDM system was also discussed, and how the skylight installation would be performed. This meeting took just over an hour, and the project lead departed around 9:30 Roof Report, June 23 2011: We installed one of the two skylights, but the second was incorrectly sized and the order needs to be placed again. The client was very understanding, and we will get back to them as soon as the replacement comes in. Roof Report, July 12 2011: We received the replacement skylight last Thursday [July 7] but were unable to install it with inclement weather over the weekend. The plan is to install it the next nice day that comes about; we need at least one hour of dry weather to perform the installation. Roof Report, October 26 2011: The client notified us that there was some moisture coming in from the roof in an area where renovations were still in progress. Give that there was no rain this day, we were confused about where the moisture could be coming in. We sent over one of our crew members to attend to the concern and evaluate what repair options are necessary. Roof Report, October 27 2011: The client notified us again about a problem with the roof, this time the concern lay with the recently installed skylight. It would appear that some moisture was dripping down around the lower edge, so they requested that we look into it and make the necessary repairs before winter. Our teams were backed up with work, but we promised to send out a repair crew as soon as possible. Roof Report, November 10 2011: We arrived on-site for 1:30pm, and spoke briefly with the client before they had to leave for another meeting. The crew assessed the skylight and determined the materials needed for a proper repair. Furthermore, we cut open the bathroom fan flashing and the roof deck to access the connection at the master bedroom. As the flashings were about to be replaced with new ones, it began to rain. Temporary patches were put in place, and the client was advised not to use the fan for the evening and that we would return the following day.

We cut open the bathroom fan roof flashing to access the master bedroom. The insulators we were working with needed to know the amount of materials they would have to requisition and whether any or all of it required removal.

The client had also reported leaks entering the building around the vicinity of this plumbing vent.

Coupled with a failing sealant system, the base of the unit was also peeling apart.

We removed the vent and decking to inspect for moist insulation and general water damage at the connections.
 
Roof Report, November 11 2011: Our repair crew spent the day on-site to address the leaking skylight. They began by removing the skylight itself and cleaned off the old membrane. Next, the curb was rebuilt to an 8-inch height, and the bottom was detailed with 2" x 2" for a solid sub-straight for drywalling. The entire skylight had to be dismantled for proper access to the membrane, so it was reassembled, caulked, tooled, and reinstallation. After the skylight was dealt with, we spoke to the client and let them know that we would return the following morning to give the same examinations and repairs to the bathroom fans and the soft spots at the each end of the ridge. Roof Report, November 14 2011: On this day, the GRS crew members arrived for 9am and spoke with the client to let them know of the scope of work for the day. We managed to repair both of the bathroom fan details, and half of the lower skylight (ran out of materials). All that remains (beyond the skylight) is the soft spot on the ridge, which should be repaired tomorrow with proper materials on-hand.
