Residential EPDM Roof Replacement, October 2015, Edmonton

This client's home bears a low-slope roof that they wished for GRS to replace with an EPDM system. The crew of technicians went out to their location and completed the roof replacement in two days' work.   Materials List: October 13, 2015 Two technicians went out to the client's location and inspected the roof for what kind of deficiencies might be encountered during the roof replacement. During their inspection, they noted down the expected materials that would be required for the job.
  • 2x Rolls of EPDM
  • 7x Pails of EPDM bonding adhesive
  • 1x Pail of primer
  • 1x 6" roll of form flash
  • 2x Pipe boots
  • (84) 4' x 4' sheets of fiber board
  • 4x Roller cages and sleeves
  • 1x Box of seam tape
  Roof Report: October 16, 2015 The team arrived on site for 8:00am, and had their disposal bin arrive by 9:00. At that point, they were already underway ripping off the old roofing system and making good progress. It was after then that they found that there was no plywood with the order, just 2x6 boards. They departed to get the requisite plywood, and returned an hour later around noon. The boards were all mechanically fastened into place, with some of the EPDM laid atop it. The crew departed in the early evening, set to return the following day and focus on the remaining EPDM and metal flashing.

We removed the existing EPDM system until the plywood was exposed. Many of the boards were either rotting or had holes in them.

Rotted wood that had eventually given way, creating a prominent hole in the assembly.

After installing new fiber boards over the assembly, we applied bonding adhesive to the underside of the EPDM.
    Roof Report: October 18 The reporting technicians notes were brief, but the site is now marked complete with the EPDM and flashing that was left over from the previous day's work. Everything went well and the roof was covered without any issue or hindrance of note.

Edmonton Rooftop Balcony Leak Repair, July 2015

Rooftop Balcony Leak Repair Edmonton - Below you will find a series of ongoing reports for a residential client in Edmonton, Alberta. The client requires leak maintenance where a PVC rooftop deck and a tar and gravel flat roof connect and flat roof recovery or replacement to the tar and gravel flat roof. Project manager notes have also been included.  This single family home in Edmonton Alberta has a second story rooftop deck (a deck that is over a heated living space is considered a rooftop deck - it needs a membrane suitable for over heated living spaces such as a flat roof membrane). It issue is the homeowners recently purchased the home and came to realize the second story balcony was leaking in to the home causing significant damage. So they hired a deck company to replace the membrane on the deck, but the decking company could not re-connect the balcony membrane to the tar and gravel roof that runs around the house as a skirt. The home-owner asked us to inspect the tar and gravel flat roof skirt and the need for the rooftop deck membrane to be connected properly (the deck membrane that was recently installed is a PVC and the PVC will not of course bond to a tar and gravel roof so a break needs to be constructed and then both the PVC deck membrane and the tar and gravel roof need to be tied in correctly). They also asked us to inspect the tar and gravel flat roof on top of the house. Update (07-30-2015): More posts to come as the work continues at this site. Update (07-30-2015): Quotation added New Client Call, July 24 2015:
  • Service: Roofing
  • Type: Residential flat roof
  • We have small issue with the roof section that joins up with the deck. There is water infiltration culminating in leaks.
Background The client purchased their home a few years ago; it is two storeys. The second story has a walk-out balcony over a heated living space. The balcony itself connected to a tar and gravel roof skirt that goes around the house. The balcony membrane was in a failed condition, so they had it replaced with a "vinyl" deck membrane not long ago. An inspection will also be required for the tar and gravel flat roof on the main roof. Concerns:
  1. The flat roof skirt that wraps the house which connects to the vinyl deck needs an assessment for replacement options.
  2. Most recently, there was a water ingress as the previous decking contractor did not correctly set a temporary waterproof scenario where the deck meets the flat roof skirt. An infrared technologist was called in and said there is no considerable issues in the walls, but considering the flat roof skirt's age there may be an issue with rotting joists or sheathing.
  3. An inspection is required on the connection area between the vinyl deck and the flat roof skirt. Is there a suitable break between the two sections appropriate for us to roof in the skirt properly?
  4. Inspect the main flat roof above for any maintenance concerns and estimate the expected life-cycle for future replacement considerations.
  5. Ask the client for the manufacturer name of the vinyl used for the most recent roof/deck replacement. When a roof deck is installed over a heated living space, there needs to be a product that is intended not only for use as a deck membrane, but also as a rooftop (low slope) roof membrane.
Assessment, July 25 2015: We arrived on-site at 1:00 pm and the client asked how much it would cost for us to only tie-in the new DuraDek material to the little roof that goes around the house as well as both ends where the deck and roof meets. The roof itself is a BUR roof and it was leaking into the house on the left side. The other end is fine, but the client wants some tie-in maintenance done there as well. We also did a main roof inspection for completeness.
