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.

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.

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.

  Installation, July 20 2015: When I arrived on-site, the client showed me two leaks. One was in the living room and another in a bedroom. Both leaks were in line with each other. On the roof, a crack running half the length of the roof was found - the same cracked that was fixed the year before. The crack had probably reoccurred due to a lack of insulation and venting. We fixed the crack again with LR and the client was notified about the insulation and ventilation.

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

  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.

Residential Flat Roof Repair Edmonton, June 9 2015

Article: Residential Flat Roof Repair Edmonton, Alberta. EPDM Low Slope Roof Membrane.

Repair of an EPDM low slope roof on a residential home in Edmonton, Alberta. The low slope (flat) roof transitions to a pitched shingle roof. Penetrations and challenges include chimney, skylights, vents, drainage, ice damming, and insulating value on low slope. Additionally the transition between the low and steep roof systems posed challenges. Also a section on choosing the correct low slope membrane and roof assembly.
This customer had originally called us when Edmonton had set records for snow-fall in January of 2012. She had significant snow loads on her roof and the concern was that her roof may collapse. So we removed the snow from her roof and discovered significant ice damming challenges on the low slope portion.
We returned in 2013 and 2014 to do regular roof snow removal because every-time the snow built up on the roof the heat from inside her home would get to the underside of the low slope roof sheathing and cause ice damming. The ice dams would then get in between the laps of the existing roof membrane and result in leaks.
Mid 2014 she contacted us to quote on the replacement of the low slope roofing with hopes of solving the problem.
We quoted the various options for low slope roofing membranes, which included; Spray Foam (SPF), Tar and Gravel, SBS Torch-On, EPDM, TPO, PVC and Liquid Rubber.
Our standard quotations include pricing for the different options available for flat roof system membranes, a roof inspection report, a write-up on the pro's and con's of each type of system and our recommendations for your most suitable roof membrane choices.
Below is a sample flat roof quotation. The first link is a PDF download and the second is a Word Doc file download.
Our customer chose to replace her failing tar and gravel built up roof with an EPDM single ply membrane roof recovery (or retro-fit). This means that we removed the gravel and skinned the bitumen membrane off and then mechanically fastened a roof board and then fully adhered the EPDM. We also did some drain work and scupper work. Our customer did not opt for a complete removal, re-sloping with an engineered slope insulation system, or any additional R value added which could also have been done with simple rigid type insulation boards.
In early 2015 our customer had called with leaks to the low slope membrane - the ice dams were back. This is an important lesson in choosing the correct roof membrane, insulation, drainage, re-sloping and more. Had we been able to re-slope the roof and been able to add insulation value, the heat from the inside of the home would not escape and get to the underside of the roof membrane and cause ice damming. But, the customer requested the least expensive options and even though our reports (see link above for sample quotation and inspection report) explain in detail most considerations, this is the way it was requested to be done by the customer.
So this spring we returned to find the same ice damming causing issues with a now new membrane. We also found drainage issues which were expected - the roof was ponding because a re-slope was not in our scope. And there were some technical (debatable) installation tweaks that may or may not have been required. Nonetheless, we now had a new roof leaking the year after it was installed.
So of course we once again suggested the upgrade options to alleviate the issue but the customer would have nothing with that and requested we simply do the repairs and move on.
Below is an account from the crew of the type of repairs they did to try and mitigate any issues in the future (full well knowing that the prime aggravating factors are insulation value and sloping).
May 5, 2015: Crew Attends to Residential Flat Roof Repair.  We arrived on site at 9:58. We started the day with the toolbox meeting and safety documents. We then went up on roof to determine an installation plan. The scope of work we decided on and did is as follows.
Scope of Work # 1 The first step was to pull all EPDM down to flat roof from under the shingles at the bottom of the sloped roof. This reinstall was to ensure no water could be coming from the flat roof to steep pitch roof transition. We then had to remove all metal flashing from around the two skylights and chimney on the roof. Once we had all the EPDM pulled we started lifting shingles along the first few rows of the sloped roof and applied the EPDM bonding adhesive. This was done under the first couple layers of shingles and to the underside of the EPDM. We then installed the EPDM back under the shingles. Then next step was to apply a bead of water block on the edge of the EPDM under the shingles. Once that was complete we secured EPDM by screwing a piece of turn-bar down on the edge of the EPDM where the water block bead was applied.
Scope of Work # 2 The crew arrived on site at 1 pm and started working on the cricket behind the chimney.  He started by cutting a piece of EPDM 7'x3'. He then had to take the Epdm bonding adhesive and apply in the same manner as the work in scope # 1 by applying the adhesive under the shingles as well as the under side of the Epdm. Once the 7'x3' piece was installed he started working on the corners. Using quick prime and seam tape he seamed in the corners of the Epdm around the chimney.
 
WORK LEFT TO DO: -patch corners -more turn bar and water block -install and or replace shingles Roughly 6 hours of work left to complete.
MATERIALS USED: -7'x3' piece of EPDM -EPDM bonding adhesive 1/3 of a pail -screws -30 ' of termination bar - 2 tubes of water block -tube of caulking for skylights -half a tube of lap sealer for temporary seals -6 feet of seam tape - quick prime 1/8th of a pail.

May 8, 2015: Residential Flat Roof Repair Crew Attends.
We started at 7:30 AM with a daily tool box meeting. We then got up on the roof and started shoveling snow away from work area so we could complete today's scope of work.
Scope #1. Scope one consisted of applying corner patches to the rear corners of the chimney. The next step was to apply tape primer to the EPDM surface on the corner of the chimney. We then cut 6"×6" squares of 6" covers strip  to use at the corner patch.  We applied  this piece on top of the tape primer and let it sit to cure.
Scope #2. Install termination bar for the EPDM on the front of the skylights. For this we measured and cut a piece of turn bar to fit the front side of the sky light. We then screwed (mechanically fastened) the termination bar.
Scope #3. We had to take the bottom two layers of shingles off and replace with new ones. For this we had to carefully lift the bottom rows of shingles and pry out the nails so the shingles would slide out. We then took the new shingles and installed them. This consisted of laying down the first layer and nailing in place. The next step was to put on the second row of shingles which slid under the old existing one and nailed in place half way down the first shingle we layer down. Job is complete.

Roof Eavestrough Repair and Waterproofing, June 3, 2015

ARTICLE: Eavestrough Repair Edmonton, Alberta. Installing Drip Edge for Proper Waterproofing at Fascia to Gutter Area. Installing Downspout Extensions for Drainage From Basement. Replace Damaged Downspouts.

Eavestrough Repair Edmonton. How to Maintain Your Eavestrough and Downspouts for Effective Building Envelope Water Proofing and Foundation Waterproofing. 

The scope of work for this work site covered a number of waterproofing essentials. The primary waterproofing issues that were fixed were:

1. Foundation Waterproofing. The objective being terminating water away from your foundation for proper drainage and extending the life span of your basement.

To effectively waterproof your basement you must have a yard that is sloped away from the basement and you must also terminate roof rain water away from the foundation of your building.

In this instance the crew installed downspout extensions to achieve the goal.

2. Building Envelope Waterproofing. A. The objective in this instance is for rain water coming down the slope of the roof to terminate in the eaves-trough and not run between the fascia and gutter. B. The secondary objective is to prevent ice dams that build up in gutters to creep up under the shingles and on to the roof deck causing deck rot and possibly leaks.

A. When water comes off the roof and misses the gutter and goes between the gutter and fascia it may cause problems with your foundation and may cause ice dam problems or water ingress in to your soffit area. This can rot out your roof assembly at the soffit and fascia area.

To correct this our crew installed roof eave edge drip flashing along the length of the eave deck sheathing. This will cause the rain water to terminate in the gutter instead of running between the gutter and fascia.

B. Installing drip edge will also help (nominally) ice dams not get to the sheathing and rot out the roof deck. For optimum waterproofing at the eave edge you would want to install ice and water membrane on the sheathing so that if the ice from the gutter gets up and under the shingles and over the drip edge and on to the sheathing and melts then the ice and water underlay will protect the sheathing and avoid leaks. In this example it was not in our scope of work.

May 21, 2015: Crew Attends Site for Eaves-trough Maintenance and Waterproofing Tasks.

Site Location: 16310 Stony Plain Road Edmonton, Alberta.

Location Type: Commercial, Institutional.

3:30 pm we arrived on site. Performed safety protocol and site meeting.

SCOPE OF WORK: We installed 80 feet of drip edge metal flashing along the south side of the building (by the side entry) as well as to the north side of the building. To install the drip edge flashing we used roofing nails to secure the drip edge flashing to the deck side of the eave edge of the roof to allow for water run-off to enter gutter. The problem the customer was experiencing was water running down the sloped roof and getting between the gutters and the fascia and not actually getting in to the gutters.

After that was complete the next scope of work was install downspout extensions and to build brackets out of wood to help the down pipes stay off the ground. The extensions will now run the water away from the foundation of the property. For the brackets we cut and measured pieces of wood to rest the down pipe on. Once these were built we painted them brown to match the down pipe.

We also had to replace two pieces of down pipe as they were damaged .

6 pm leave site.

Roof Deck Drainage and Waterproofing

ARTICLE:  Roof Deck Drainage Problems. Waterproofing a 2 Ply SBS Modified Bitumen Roof Balcony in Edmonton, Alberta.

Recommendations for Waterproofing Outdoor Decks Over Conditioned Living Space. Roof Deck Drainage and Waterproofing - Inspection and Repair of a Torch-On Flat Roof on Outdoor Balcony at Multi-Family Condominium. Customers regularly call on us to have roof assessments (inspections) completed. During a roof assessment our journeyman roofers assess the roofs condition. We assess the roof for preventative maintenance reasons as well as inspecting existing problems that the customer is pointing out. We then discuss different scopes of work fix the problems as well as potential materials and costs related to the repairs. One of the most common calls we get for inspections and repairs are rooftop decks, balconies and patios. The primary reason the failure rate on rooftop decks is so high is because of the original installation. It is common for incorrect membrane choice to be the reason. In other words, many people install an outdoor deck membrane that is intended only for an outdoor deck and not a membrane for over a heated living space. If your rooftop deck or balcony is over a heated living area you require a special membrane that is also intended for low slope roofing (as well as deck waterproofing) and is approved for use over a conditioned living space. Common products for this are Dura-Deck or DecTec, both of which are a PVC membrane that are suitable to be walked on (so they do not require a floating deck over top) and they manufacture membranes suitable for over a conditioned living space. We use DecTec extensively and have had great results with it. Or, also common is the installation of a membrane that won't hold up to the foot traffic associated with outdoor living areas. Other reasons include simple age, wear and tear, drainage and issues relating to penetrations or floating deck assemblies on top of the membrane. Visit our main website for more information on rooftop deck waterproofing. This particular inspection and subsequent repairs was more focused toward an aging membrane and the associated repairs that come with not properly maintaining the deck membrane and building envelope over the years. The drainage problems were causing significant damage to the exterior of the building. Below you will find the inspection report.
