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.

Photo Journal: Flat Roof Leak Inspection Edmonton AB, March 2014

Flat Roof Leak Inspection Edmonton - Below you will find a photo journal and emergency roof repair assessment from our Edmonton roofing repair crew at a commercial roofing site. Although the call began as a tar and gravel flat roof leak repair, the extent of damage escalated to the client requesting a quotation for flat roof recovery or replacement options. More field reports will be posted as they become available for this site. Regular Flat Roof Maintenance Will Save You Money. If you own a flat roof it is critical for you to conduct regular inspections, maintenance and repairs as needed. You will save considerable money if you do this twice per year. The reason it saves you money is that a complete flat roof replacement is expensive and 9 in 10 times had maintenance been done the replacement would not be required. If you do not do regular inspections and maintenance you could face a catastrophic failure which has occurred to this roof below. Simple spring and fall inspection and maintenance would have avoided a costly re-roof. Click here for a proper flat roof inspection and maintenance check-list. Emergency Flat Roof Inspection Edmonton, March 29 2014: Flat Roof Leaks. There are multiple large leak problems on this commercial tar and gravel flat roof that are currently being managed with buckets. Flat Roof Ponding. The roof assembly is carrying considerable ponding all over that is definitely a concern with dead weight load on the roof in times of sudden storms or in winter freeze thaw situations. Roof Drains. There are two drains on the roof that are useless; the previous contractors did not sump them properly. Roof Maintenance. Previous roof maintenance contractors did not remove the gravel before using tar to patch spots that needed repair. An excessive amount of tar has also allowed trapped air to cause blistering. Gum Boxes. Four gum boxes were actually near open water, and it was able to get into them. This is also contributing to some of the leaks. Roof Membrane. The tar and gravel roof membrane has become weather cracked from the sun, contributed by an improper ballast spread. If the pea gravel is not covering the bitumen layers the UV of the sun will dry out the bitumen causing it to crack and ultimately leak. Blisters. There is mass blistering of the roof membrane in multiple areas. If they continue, water will enter there as well. Several of the blisters on the roof are cratering water into them. Temporary Flat Roof Repairs. While we were on-site, we attempted to drain as much water as possible. The client called off the temporary repairs since the problems have become greater than simple roof maintenance work. The client has requested a quotation on roof replacement or recovery options.

Ongoing Roof Leak Maintenance in Sherwood Park AB, May to July 2015

Assessment, May 7 2015: The site had a plumbing issue; the drain was backed up. Our client said if there were any roofing problems in the future, that they would definitely contact us. Surely enough, we received a call the next month. Scope of Work, June 1 2015: We are to locate and fix the leaks of a BUR roof and add one drain basket to the drain. When we got up to the roof, we had to locate two leaks which were both in the center of the roof but about 15 ft. away from each other. Once we swept all the gravel back, we noticed there had been two large gum patches that were previously installed by another contractor and had now failed. To test for failure, I pushed water out of the areas in the patch. We spudded both areas. One leak was 12 ft. x 1.5 ft. and the second was 10 ft. x 3 ft. Each tapered down to 1 ft. once both areas were spudded. Underneath, there were signs of water saturation, so we had to dry each area with a shop vac. Once dry, we then gave them a coat of asphalt prime to help the MASTIC bond on the BUR system. Once priming was complete, we then applied a coat of MASTIC to the entire system followed by a layer of reinforcement mesh. Another top coat of MASTIC was applied to seal in the mesh.
20150601_104710
We cleared gravel away from sections of the roof that we suspected water was entering through.
20150601_110050
Tears were found in some parts. We used SOPRAMASTIC to seal them in.
20150601_121144
Here is another exposed section which had been a tear running over a significant section of the roof.
20150601_115104
After spudding the tear, we applied mesh over top.
20150601_120319
A second coat of spudding was then applied over the mesh.
20150601_124628
We then let the second layer of spudding dry over the mesh.
Our second scope of work was to install a drain basket. Unfortunately, this could not be accomplished because it had been completely covered with MASTIC. There was nothing to fasten the basket to. Materials:
  • 25 ft. of 3ft. mesh
  • 3x pails of MASTIC roof patch
  • 1x can of spray primer
Followup - Installation Report, June 17 2015: After filling out safety documentation, we met with the client to go over leaks on the main roof when we had performed repairs on during the previous visit. From the client's assessment, there was still apparent leaking. A crew member went up on the roof and searched but could not finding anything. We will need to return when it is leaking actually occurs to get a better idea of where it is coming from. As for the roof above the restaurant, we tracked the leak to an air unit. Once we removed the metal, paper around the base was splitting and water was getting in, evidenced by moisture. We spudded the entire perimeter and applied a coat of MASTIC, followed by a layer of reinforcement mesh, and finally a top coat of MASTIC. We then reinstalled the metal and cleaned up the site.

Quotation, June 23 2015:
  • SBS 2-ply patch along entire down-slope (60 ft. x 20 ft. patch)
  • Drain replacement with u-flows
Scope of Work: Remove all gravel in the area, spud out 10 ft. on either side of the drains, and 60 ft. down the low ride of the roof. Roll on asphalt primer and torch down the base. Add new drains with u-flows and cap the entire area. Materials:
  • 9x rolls of cap
  • 9x rolls of base
  • 10x gallons of asphalt primer
  • 2x 4 in. drains
  • 2x 4 in. U-flows
  • 2x pails of MASTIC
The client approved our quotation on the 25th of June:
Please go ahead with this job and let’s hope it solves our leaking issues.
Field Report, July 13 2015: We had our safety meeting and went up to the roof to shovel all the gravel away from the work-site and spudded the segments of interest in preparation of a patch. It started to rain and we had to call it a day.

Tar and Gravel Roofing Recovery, July 2011, Edmonton

This report follows repairs made to both levels of a client's tar and gravel roof. The gravel was removed, the roof itself patched and repaired, all before a thorough coating of liquid rubber was applied. Continue reading Tar and Gravel Roofing Recovery, July 2011, Edmonton

Residential Roof Leak Repair in Edmonton AB, July 22 2015

Below you will find an initial assessment for an ongoing residential site by our Edmonton roofing repair crew. More reports will be posted as they become available. Initial Assessment, July 22 2015: We arrived on-site at 1:00 pm and were lead by the client to two leaks in the shop. One was coming from around the skylight, and another one around the chimney stack in the middle near the edge of the roof. Upon inspecting the roof top-side, we observed that the acrylic MASTIC around the chimney was cracking and lifting in areas. It should be removed and replaced with seam tape and liquid rubber. The penetrations require the same. It is only a matter of time until it begins to leak around the entire skylight. There are also cracks and splits in the skylight, which seems to have had been coated with spray foam. The metal gum box also needs to be topped off. There is a metal boot top-side as well that looks like it was only spray foamed. The roof measurements are 85 ft. long by 51 ft. wide, and the skylight was 4 ft. x 4 ft. It should take 25 man hours to clean and repair the penetrations, apply some gum patch into the metal boot, and cover the foam/top up the gum box with rubber MASTIC. < TO BE CONTINUED > Code: 154 Contact Us Call our 24 hour emergency roof repair at 1.780.424.7663.

Ongoing Roof Leak and Drain Repair in Fort Saskatchewan, July 2015

Below you will find an ongoing series of reports for a leak repair in Fort Saskatchewan, Alberta. The site is currently a work in progress. More updates will be posted as they become available. Scope of Work, July 21 2015: Upon arriving on-site, the client advised me about two leak sites - one in the kitchen and one above a light fixture by the washroom. On the roof, there was a major water ponding issue and lack of drainage. There is also a fryer vent that has major dripping onto the rubber. The grease that is leaking out has, over time, started to eat away at it [the rubber]. Structural integrity has been lost, so the next step is to cut out the damaged area and replace it with a 12 ft. x 12 ft. EPDM fixture. The next scope of work would be to install an internal drain, piped in by a plumber. < End Report > Code: 100 Contact Us Call our 24 hour emergency roof repair at 1.780.424.7663.

Photo Journal: TPO Flat Roof Recovery and Sloped Insulation in High Level, AB

Below you will find a photo journal from a commercial contract in High Level, Alberta. The work entailed a TPO flat roof recovery and sloped insulation. Background When a roof reaches the end of its life, our clients are faced with the choice of either a full replacement or a recovery. Roof recovery refers to applying a new system over an existing one when the roof is reaching its end-of-life (1). Depending on climate conditions, preference, or preexisting solutions, a roof recovery may be performed using TPO, EPDM, bitumen, cap-sheets and/or asphalt. Sloped insulation refers to the tapering that exists on an insulation system. As a weatherproofing measure, when precipitation reaches your roof, it will run off into the drain system down the slope. Call us today for a consult on which roof recovery system is right for your commercial, industrial, or residential environment. < End Journal > Code: HIGH Article Topics: TPO Flat Roof High Level Alberta.

Roof Leak Repair in Edmonton AB, December 2014 and July 2015

Below you will find an assessment and field report from the Edmonton roof leak repair crew for a residential client. The roof had been experiencing leaks on two occasions due to a lack of proper ventilation and insulation. Assessment, December 12 2014: By the time we had arrived, the leaking had stopped. However, our client still had buckets out in her kitchen for water collection. The client also showed me the garage, where there appeared to be water damaged on the ceiling. Again, no evident leaking at the time of assessment. A roof inspection was also completed, and we found 4 in. of ice damming.

Nisku Liquid Rubber Roof Recovery, August 2011

The report below follows services carried out on a metal roof for one of our industrial clients. They sought GRS' assistance in recovering their roof with engineered liquid rubber, with some other spot repairs to complete as needed. Inspection: June 2, 2011 The GRS crew went on location to inspect the existing roof system and take photos that will help the project management group form a better idea of what service will be needed at this location. The photos appear below.
100_0006
Our client had an industrial-grade metal roof. A crew was dispatched to perform an initial inspection with regard to the scope and requirements of performing a roof recovery using engineered liquid rubber.
100_0008
Many of the screws were exposed or missing, with parts of the metal beginning to rust.
100_0009
Rusting at the seams, with exposed screws running the length of this section of the roof.
100_0010
There were signs of previous spot repairs. In this case, caulking had been applied to the screws.
100_0011
More spot repairs, with caulking applied at the seams and over the edges. This solution had expired, with cracks forming along the length of the roof where the caulking had been applied over the seams.
100_0012
Closeup of some old sealant applied over seams and around raised screws. Note the hole in the fastener that had previously been closed off. As well, there are slight buckles in the metal. Each of these deficiencies contribute to common leak entry points and a loss of a metal roof's water shedding properties.
100_0013
We inspected the wall connection, noting whether any components on the wall itself needed to be replaced, and whether we had to order any new flashing as part of the recovery.
100_0016
Sealant had previously been applied to the window sills, flashing, along the wall seams, as well as on the intersection between the flashing and the standing seams on the roof. Besides showing signs of cracking, there was also more rusting along the walls.
100_0017
Significant rusting on the flashing, with an unsealed base for the rooftop appliance. As well, the edging over the window sills is not flush with each segment. Further down, it can be seen to be curling up from the window.
  Quotation Delivered: June 6, 2011 After seeing the roofers' investigation photos and measurements, GRS' project management could deliver an accurate quotation for services to be carried out of the roof. Included in the quotation were two separate services; the engineered liquid rubber application and an EPDM installation for the area around two eaves. Also attached to the quotation were the documents and web links surrounding GRS' workmanship guarantee, system methods, schedule availability for the season, and more. There was another note mentioned that regarding schedule availability, it's best to book liquid rubber jobs earlier in the season for when it's warmer. Even though the solution will bond, it performs best when applied in warmer weather.   Roof Report: July 20, 2011 The crew went out to the client's building and got to administering trowel-grade liquid rubber to all penetrations, joints, and problematic areas that has been previously discovered. They also did a lap around the perimeter, ensuring watertightness on the high-risk parts of the roof. They then set up the pump to apply the spray-on liquid rubber and managed to cover roughly one-quarter of the roof itself. Their plan was to finish the entirety of the roof the following day, so they packed up the equipment, cleaned the site, and closed the site for the evening.

    Site Inspection: August 1, 2011   One of the senior members of GRS' crew went on-site to inspect the liquid rubber application and found it to be forming a good seal. There was some water that had formed a small bubble in the rubber, but once popped it was deemed fit for continued use as the rubber still formed a solid barrier to the metal.   Roof Report: November 25, 2011 Several months after the initial liquid rubber coating, the client call in to report some other leaks in separate areas of the roof. GRS sent a team out to the site to investigate and carry out the necessary repairs. They administered sealant to the flashing where the wall meets the north-facing roof edge, and again on the south-west corner of the building. They also sealed in the wall-to-roof spots on the west-facing wall and inspected the existing wall spray. After carrying out the spot repairs, they had a better idea of what else needed to be done to the roofing system, and returned the following report:
  • The west-facing wall where the windows are is 3' x 78'. Will need 100' x 6" skrim sheet, and roughly 16 man-hours to install it.
  • The north-facing wall is 3' x 40'. Need 50' x 6" skrim sheet for another 12 man-hours to install.
  • The west-facing wall's upper roof is 3' x 24'. Need 25'x6" skrim sheet and 10 man-hours to finish.
The site was cleaned up, and the crew departed, leaving the repair options in the hands of the client.   This report will be updated as more reports come in, should the client elect to move forward with repairs.

Flat Roof Repair Calmar Alberta, June 4, 2015.

Article: EPDM Flat Roof Repair Calmar Alberta, Commercial Building, Slope Toward Drains.

Below you will find a report from the flat roof repair crew. The issue with this roof was that a back-slope was required to get the water drainage correct. Once the back slope was installed on the flat roof the water drained from the roof much better. May 9, 2015: Crew Arrives to Complete Repair

EPDM Repair
EPDM Repair in progress. Installing a back-slope at the roof parapet to redirect water to drain.
  After filling out our safety documentation and a weekly safety meeting we went up on the roof to find about 2 inches of standing water along the back wall. We spent 2 hours getting the roof dry. Once the roof was dry we then installed our slope with screws and plates to correct the roof ponding issues. After that we put 3 inch seam tape around the perimeter of our back slope. Once that was complete we put latex in our rubber using 2  pieces as one piece. It would of been a hassle after we glued our rubber down. The crew then glued it to the seam tape all around to ensure a 100% seal. The slope turned out really good. The customer inspected the work and was happy. I also noticed 2 outside corners that where failing so I fixed them while I was there we then packed up our tools downloaded them to the truck and left site at 5 PM.
