Edmonton Roof Flashing Repair, May 2011

The report below covers an inspection and repair to a client's residential building. Their failing low-slope roof required some re-flashing, but upon first inspection it was clear that there would be more work to carry out beyond this simple job. Inquiry Received: May, 2011 The client reached out to us to provide a quote for re-roofing their low-slope residence. We sent out a technician to inspect the roofing system, and they provided the following notes. Inspection: May 7, 2011 After inspecting the roofing system and taking photos of the area, the technician carrying out the inspection send in some note about the potential project, and discussed options for replacement.
  1. The roof (overall) is in poor condition.
  2. Apart from the usual blistering and gravel wear, there are two locations where cracks have appeared.
  3. The cracks themselves are very deep, so much so that one could touch the joists below with a finger.
  4. There was what appeared to be a small hole found in one of the cracks, but when it was traced out it was found to be about a foot long. Another hole was found to similar result. Unfortunately, there's no way to tell how many such deficiencies exist.
  5. A number of on-roof drains are clogged and unusable. Will need attending to.

There are splits in the roof from top to bottom and across the top of the roof. It looks like the skin and board will need to be removed, so the client would need to be made aware of that once they returned home. As the metal is also unusable, dimensions will be taken and sent over to GRS' metal expert/journeyman for ordering new material. Roof Report: May 25, 2011 Inclement weather dogged the team as they loaded the materials onto the roof, but the rain got progressively worse. Unable to work in such conditions, the team contacted the client and explained the situation. They were very understanding and accepted the rescheduling for the following day. Roof Report: June 7, 2011 The shipment of metal came in, ready for installation. The team had it picked up and delivered onsite, then loaded it onto the roof. The metal has now been installed, sealed, and is otherwise complete.     CODE: 7824 Contact Us Call our 24 hour emergency roof repair at 1.780.424.7663.

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.

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.

Edmonton Shingle Roof Repairs, April 2011

The report below follows repairs made to a shingle roof on our client's residence. They required a section of shingles replaced, addressing a leak coming in through the area. Quotation Delivered: April 11, 2011 We sent out one of our technicians to perform an investigation of the roof that would form the basis of a quote for services rendered. Included in the quote was our spring season availability, and we eventually booked them for service in late April. Roof Report: April 24, 2011 The technician arrived on site for 8:30am, and got to work removing the affected shingles and hunting down the leaking area. This carried through 11:30 when they departed for lunch and to pick up more materials. They returned to continue work at 12:30, repairing the leak and replacing the removed shingles until 3:00pm. The repairs involved opening up the vent area between trusses and reinstalling the plywood, membrane, and shingles. In addition to the above, four downspouts were installed (14' each). Service Followup: September 11, 2011 The client reached out to us, advising that they had come upon a leak into their garage in the midst of some rainfall. They had another roofing company come in to investigate, and had found that some of the shingles installed by the previous technician were not done to proper standard. In their email, they hoped we would honour our warranty and come do the necessary repairs. We sent out one of our own technicians, who were able to corroborate the other company's findings - some of the shingles were not fully overlapping to the accepted standard. Our technician brought two bundles of shingles to the site, and had to leave briefly to get a third. The 'old' shingles were removed and the ice and water membrane reapplied. Then, new shingles were affixed properly to finish repairs to the faulty area.

Roof Retrofitting in Unity SK, August to October 2010

Below you will find a series of Roof Reports and photos from our roofing repair crew in Unity, Saskatchewan. The client asked us to perform some retrofitting and approved some assessments that were made on-site. Roof retrofitting and leak mitigation was provided.

Roof Report, August 24 2010:

We opened one ventilation unit which was found to have traces of moisture. It was water-tested, which came back positive as a leak area. We also found areas that had open wire penetrations and gas lines going into the building. A cut-test was also performed, where 4-ply styrofoam insulation (5") and a vapour barrier was found. This might explain why water had to travel some distance before it appeared as a leak, since the rest of the roof is in good shape. Areas requiring maintenance were sealed with mash, mastic and additional caulking as required. Client Callback, October 21 2010: After TPO recovery, the client found more water leaking at grade-level. We resolved the issue with caulking around the problem area. < End Report > Code: 120 Contact Us Call our 24 Hour Emergency Roof Repair at 1.780.424.7663.

  1. Site Visit Done. Initial Assessment Completed. Photos on file (see Krain Consulting report).
  2. Options for roof replacement, roof overlay, repairs, and regular maintenance attached.
    1. Full roof replacement is not required except at garage portion where the installation crew will determine how much to take out when they open roofing system.
    2. An EPDM, TPO, or PVC roofing system overlay is a reasonable option for this roof.
    3. A roof overlay saves significant costs, provides environmental relief as old system does not end up in the waste, and all the roof overlay systems are very successful.
    4. The deciding factor when considering a roof overlay is whether the preference is a black roof (drawing the sun in) or a white roof (a cool roof for more efficient function).
    5. Repairs to existing roof is a consideration, but not recommended considering the number of failures.
  3. Roof Flashing.
    1. The existing roof flashing is in moderately good shape. It could be replaced but it is most definitely not required. We suggest keeping as much of the old flashing as possible.
    2. We suggest keeping as much of the old flashing in place as possible. When the new roofing system is retrofitted, the Senior Installation Manager would instruct the crew to save as much of the old flashing as possible (unless client decides to simply replace all flashings).
    3. The roof flashing invoicing (whether all new is ordered or the existing flashing is modified) would be a separate invoice. Our sheet metal / flashing crew is about two weeks behind our flat roof membrane applicators so we would bill the flashing separate of the roofing system.
  4. Eaves, Downs, and Scuppers.
    1. Crew to be instructed to slope roof in such a way that the flow of water moves toward the east and south.
    2. Custom fabricated architecturally designed eaves and gutters with external scuppers (drainage to gutter area) will be added to back of home and east side. Client and installation manager to determine where the downspouts will send water to on east side of property.
5. Perform regular maintenance once or twice per year thereafter.
