Edmonton Residential Flat Roof Inspection and Replacement, June 2011

This project started with an inspection of the client's residential roof as the owner wanted options for replacement. Our project manager provided a comprehensive quotation outlining various options for replacement and recovery. The client wanted options for both the house and the garage. Upon first inspection it was determined that the leakage in the garage was occurring at the flashings, which all need to be replaced. Our crew was informed that a tree had fallen on the rear portion of the garage which is evident from the damage there. The roof itself is not in good shape and has many soft spots, one area even has a foot long bubble on it. There is also a tear about 8 inches long. The inspection of the roof on the house was not quite as bad as the garage; however, there was one soft spot located around the drain. It is possible that the insulation underneath is beginning to saturate with water. Normal blistering on the roof is evident of the roof coming to the end of its life. The flashing is also an issue with one hole caused by the adjacent tree. The client is open to all available options.
SG1S3311
We began work on this site with a comprehensive inspection, covering both the house and the garage.
SG1S3312
The client had a double-detached garage with a flat roof.
SG1S3313
Similarly, the house was a detached trailer with a patio, both having flat roofs.
SG1S3316
We began the garage inspection by doing a walk-around of the perimeter, noting any deficiencies in the flashing. It was determined that the leaks were entering around here, and that all of the flashing needed to be replaced.
SG1S3319
Next, we noted the extent of the damage on the garage roof and determined whether they warranted a replacement or recovery. Part of our quotation included whether components such as this gas appliance required replacement, as well.
SG1S3320
Rusting, cracked sealant, and exposed seams in the flashing were pinpointed as the main leak entry points into the garage.
SG1S3321
There had been signs of previous spot repairs, which had failed to prevent leaks.
SG1S3322
Significant crumpling and rust in the edge flashing, with unfastened components visible.
SG1S3326
Some spot repairs had been performed at the drain leading to the downspouts, as well. Again, the sealant was failing, and water did not drain properly.
SG1S3328
Furthermore, we found significant tearing in the roof membrane itself.
SG1S3330
Some of the tears had been sealed in using liquid rubber in the past, as well. No leaks were found inside the building that corresponded with this section of the roof.
SG1S3331
Next, we moved onto the house inspection. We checked the soffit, fascia, and all perimeter flashing for deficiencies and potential leak entry points.
SG1S3333
There was normal blistering throughout the roof, indicating that it was close to the end of its life cycle.
SG1S3334
We postulated that the insulation underneath the roof was beginning to saturate with water, thus the red marks.
SG1S3336
As with the garage, parts of the fascia were unfastened.
SG1S3337
Exposed pockets such as this along the flashing also provided leak entry points.
SG1S3338
Missing or exposed screws and failing spot repairs were found along the perimeter.
SG1S3340
The base of this chimney was not flush with the roof. This provided another potential leak entry point.
SG1S3342
The chimney stack showed no signs of major damage, although the rest of the base had significant deficiencies as noted above.
SG1S3343
More exposed pockets along the chimney.
SG1S3344
The patio had a low-slope metal roof. At first glance, it did not require replacement. The client did not report any leaking coming into the patio.
SG1S3345
Finally, we did a check around the various rooftop appliances and fixtures. The skylight's penetrations were not properly sealed, as with most of the other appliances.
The following is an email sent by our project manager to the client providing a quotation for various roofing options:
Good morning, Please find attached the pricing you requested. Both your home and garage is priced. The documentation and internet links in the attached report detail our; Workmanship Guarantee, System Options and Methods, Credentials, 2011 Schedule Availability, Links to Manufacturers, GRS Project Portfolio and Clients, etc. There are two different methods to do your roof, one is to rip the old roof off (a complete replacement) and the other is a new Roof Recovery System. A Roof Recovery has our crew scraping the gravel off, taking the old membrane and soaked insulation off (as required only) and then mechanically attaching a fibre board and then putting a new roof over top (SBS Torch On, Tar and Gravel Mop On, EPDM, TPO, or PVC per quote). Typically a roof recovery is what is done. A roof recovery is less intrusive, it is more environmentally friendly as the old bitumen layers don't end up in the land fill, the old system also has an inherent R Value of usually around 7, it is less costly, and the life-cycle is the same as a complete replacement. However, if you find that you want or are required to completely remove the old system down to the substrate (the sheathing or metal Q deck), we can accommodate this and the pricing is included in the attached documentation also. Additionally, there are a number of different membranes available, which I've detailed in the quote. Essentially, it comes down to 1) A traditional 4ply mop on tar and gravel (BUR), 2) 2ply SBS Mod Bit (torch down or cold apply), or 3) Single ply; black rubber membrane (EPDM) or a white membrane (TPO or PVC) depending on whether you want to draw the sun in or not. EPDM, TPO, PVC are available in multiple colors, however EPDM out of the box is typically black and TPO / PVC are typically white. Single ply systems are what are being installed more and more now (for GRS singly ply is about 80%), however, we install all system types. I would encourage you to consider the life-cycle costing and maintenance / repair benefits of a single ply system prior to choosing a system. Have a read and let us know what you think - I know there is a lot of information so I'm sure you will have questions. Thanks for the opportunity to quote - it is appreciated!

Fort Saskatchewan Commercial Roof Inspection, June 2011

This commercial client required an inspection and subsequent quotation for various roof replacement options. This report follows the initial inspection with photos. Also included is an email sent to the client by our project manager.
Inspection, June 22, 2011: This roof is in very poor condition. We had some difficulties communicating with the clients as they speak a different language. I do know that a different person other than the owner called but no luck getting a hold of him. Regardless, this roof needs replacing.
  • It is very squishy in areas towards the middle.
  • A very strong smell of mold and rot. I couldn't tell if it came from the roof in general or somewhere else.
  • The flashing has some areas where repair is needed (as documented) but it is generally okay.
This is a Tar and Gravel rooftop which has soft spots all over it and a moldy mildew stench. There is no option for repair, this roof needs replacement. The sheathing could be done as well.

SG1S3164
Front view of the building we inspected. The client had a tar and gravel roof and was looking for quotations to replace it.
SG1S3165
There were clear signs of age from its outward appearance. The metal components were rusting, and a lot of the paint had worn off.
SG1S3167
There was significant standing water throughout the roof, which meant that the roof was no longer sloped correctly or drainage systems had failed.
SG1S3169
Standing water had also accumulated around various electrical systems, which presented an obvious danger in terms of public safety and the functioning of the building.
SG1S3171 We found a variety of fungal growth, and scent from the same, on the roof. The client didn't report any problems inside of the structure with respect to mold.
SG1S3175
Some of the flashing against the walls and the edges had been bent or crumpled. Other sections were no longer flush against the roof surface and formed pockets through which water could enter.
SG1S3181
Example of a pocket in the wall flashing.
SG1S3179
We identified this clogged drain, which would require a plumber to perform repairs.
SG1S3173
Water had been entering the building through exposed seams in the wall flashing and along the perimeter. Many of the bases for the rooftop appliances were also vulnerable due to failed sealing.
SG1S3176
Some of the cap flashing had completely fallen off during a windstorm There was no maintenance done topside to ensure that it was fastened correctly.
SG1S3182
Pieces of flashing that are not flush with each other create pockets. In this case, there is also a hole in the metal near the roof surface .

Edmonton Residential Roof Warranty Repair Call, June 2011

This report follows a warranty dispatch for a residential client who needed several shingles repaired. An initial inspection was done followed by the shingle repair. The client first called us to determine whether or not her warranty was still valid as there had been some damage to several of her shingles. A crew member was dispatched to inspect the rooftop and obtain a sample of the existing shingles. Our crew determined that the shingles were under warranty and will be doing the repairs for the client. Repairs commenced on the next visit and a crew member was able to remove three wind damaged shingles. These were replaced with brand new ones. After this the crew member spoke with the client and ensured that the warranty forms were filled out properly. The site was then cleaned up and the client was satisfied with the repair work.
1
Several of the shingles had been damaged during heavy weather conditions. The roof was still under warranty.

We replaced the damaged shingles and wrapped up the site.

Drayton Valley Commercial Roof Leak Repair, June 2011

This article covers a commercial leak repair in Drayton Valley and also includes a follow-up service call. Photos relating to both service calls are supplied. Roof Report, June 7, 2011: First I met with the manager on-site and examined the leak areas from the inside. Then I went onto the roof and began examining the suspect areas around RTU (rooftop unit) #4 and RTU #6. I found loose curb stripping under the flashing but was unable to repair at that time due to heavy rainfall. I advised the manager that I would return the next day. Roof Report, June 8, 2011: I informed the staff on-site that I would be working on roof. Then I went onto the roof and removed and replaced the flashing. Lastly I repaired the stripping with ModBit compatible mastic (2 tubes).
IMG_0682
Significant leaking had entered the building through the roof and had visibly stained many of the ceiling panels.
IMG_0718
The inspection revealed crumpled base flashing, an unfastened termination bar, and exposed seams on the roof surface around a unit.
IMG_0717
For the first unit, we removed the base flashing and applied liquid rubber around all of the seams.
IMG_0713
Clear water staining on the roof surface around this unit, with a small trail leading into it. This indicated where leaks were entering into the building from.
IMG_0711
The leak lead to an exposed seam underneath the unit, which was slightly tearing apart. We applied coatings over the deficient sections.
IMG_0704
The same process was repeated for the second unit. We completed removed the old flashing to expose the base.
IMG_0712
After coating over any tears along the seams, or pockets
IMG_0710
As with the other unit, there were clear paths of where water was entering from into the building.
IMG_0692
The edge of the roof had significant waterpooling, indicating that it was not sloped correctly or the drainage systems were failing.
IMG_0691
Another pattern of entry could have been a critical amount of standing water leaking through the base of these vents.
IMG_0689
Most of the roof had significant tearing along its seams, and there were signs that water had been standing throughout the roof -as indicated by these white stains.
  Follow-up, June 12, 2012: The following email was sent by the client's maintenance manager prompting a follow-up service call:
In speaking with the store, water seems to be entering the store when it rains. From the description the manager noted, it seems the curb flashing on one of the roof top units may require attention as the water is running along side the supply air duct work that protrudes through the roof. Our HVAC vendor was on-site in May to complete an inspection and had not noted there to be any obvious concerns at that time. However, they are not due back until mid-July or so. The area is to the right hand side of the check out area. One ceiling tile is obviously wet. It would be appreciated if you may confirm to have your roofing vendor out within the next day or so while the weather is favourable to make such a repair. Once complete, please do ensure to have any interior water damages as results (ie, water stained or missing ceiling tiles) addressed. Please do advise as to your roofer's anticipated arrival. For the time being the store has been putting a bucket in the area to catch the water whenever it rains. Regards,
Roof Report, June 13, 2012: We arrived on-site and inspected the damage from the inside. After gaining access to the roof, we identified the problem area as being an HVAC unit near the southwest corner. To determine exactly where the leak was coming from, we performed a leak test. We brought buckets of water up onto the roof and splashed it all around the HVAC unit. A total of 8 buckets of water were used in this test, but we did not manage to find the problem. It was determined that in order to accurately find the leak we would have to wait for the rain to come. The downspouts appear to be crushed near the bottom, and the northern most down spout seems to be half missing. The pooling of water by the downspouts has to do with the location; the parking lot asphalt where the spouts are is sloped in a way that the water pools by the eastern wall of the building.
IMG_1875
Water ingress had occurred during rainfalls. Although not as significant as before, some ceiling panels were once again stained by the leaks.
IMG_1876
We inspected the attic again for signs of leaking around the newly stained panels. This would help us pinpoint where water tests ought to be performed on the roof.
IMG_1877
One of the downspouts was crushed near the bottom, with rusting all throughout.
IMG_1879
The downspout on the northern side of the building was half-missing. On both accounts, water was pooling by the wall due to the slope of the parking lot.
IMG_1880
We went back to the roof to do some water testing. The leak entry point was pinned down to an HVAC unit in the southwest corner of the building.
IMG_1883
Since the client had not approved a roof recovery, replacement, or re-sloping, we had once again found significant waterpooling on the roof. However, water was not entering the building through the vent it was adjacent to in this case.
IMG_1884
One of the candidate units had some standing water around its base, as well as over a run of exposed seams on the roof surface.
IMG_1885
The flashing around the unit also had to be sealed in. Parts of the membrane around it had been forming bubbles or was beginning to curl upwards at the seams.
IMG_1890
Furthermore, the coatings that were originally applied over the seams were past their age.
IMG_1898
Water testing was performed to see what route it would take around the HVAC unit and into the building.
IMG_1904
Eight buckets of water were used for testing around the suspected units.

Commercial Roof Maintenance and Repair in Edmonton AB, January to June 2011

Below you will find a series of reports from the roofing repair crew from the period of January to June for a large commercial client in Edmonton, Alberta. From snow removal to PVC maintenance, the often large time-spans between work is evidenced by weather conditions and their effects on structural integrity. January 22 2011: The entire day was spent shoveling snow in preparation of a leak assessment. Service call, February 8 2011:
Your contact is the facility manager and expects a service call prior to servicing the leaks. Before any future work is performed, a quote must be done unless it is with respect to repairs from shoveling. Note that one of our workers said there is a section that needs repair from a leak that was not caused by our shoveling.
There had been sub-zero conditions in Edmonton that month. We provided the client with an update when the weather was beginning to become favourable. February 27 2011:
As you know, we had temporarily sealed the various points where leakage was occurring as well as spots where we noticed tears. We have also received the Sarnafil that we had special ordered for your site. The next step is to wait the sub-zero weather out and get the Sarnafil patches welded on to permanently seal the deficiencies. In these temperatures that we are currently experience, the cold may prevent proper adhesion. We would rather wait it out than have to come back for another visit. If you need any further clarification, please give us a shout. We will give you a call before arrival, at any rate.
Field Report, March 18 2011: We repaired the leaks right before the afternoon broke out. Any patches that required maintenance were also attended to.
IKEA (2)
We patched over the tears that had accumulated alongside the seams.
IKEA (3)
Closeup of the patch, with some staining around it. The stains are indicative of longterm moisture buildup or standing water.
IKEA
The base of a gas appliance had a few holes as well, which we patched over.
More problems, April 19 2011:
I just got off the phone with the facility manager and he said that leaking has begun again. He believes it is in a different spot, since the leaks are exiting from the carpentry shop about 30 ft. to 40 ft. from the roof hatch.
In the meantime, a PVC repair was also added to the invoice. The weather did not let up until June. PVC Repair, June 1 2011: We called the facility manager and arrived to the facility at 10:45 am. The PVC membrane top-side is damaged in three areas and requires approximately 16 ft. cover strips to repair it. < End Report > Code: IK Call our 24 Hour Emergency Roof Repair at 1.780.424.7663.
