Edmonton Residential Roof Inspection and Replacement, August 2011

This residential client in Edmonton required an initial roof inspection followed by subsequent roof replacement. The report outlines the progress undertaken by the GRS crew and includes photos. Inspection, August 1, 2011: I met the client at his house and he told me about the leaking and ice damming problems he has been having. His soffits are currently stucco which is something that is not often seen. It appears that there is only mesh across the soffits holding the stucco so there would not be enough support to cut in soffit vents which can be used on wood soffits. I suggested removing the stucco soffit on the eaves and installing aluminum soffit and fascia to get the air flowing through the eaves as well as adding additional ventilation to the roof.  He has a neat cedar design on the gable fascia’ and would prefer to keep them as they are. We also determined that the roof is due for replacement and he would like some options other than the cedar shingles which are on the roof now. The main house is 6/12 pitch with some 12/12 dormers and gable extensions and there is a low slope section on the back which will require 100% ice & water shield as per low slope application. Material Required: note 9 sq. of this project is 12/12 pitch.
  • 50' Valley metal (brown).
  • 6 air vents (to be cut in).
  • (1) 4” plumbing flashing.
  • 100' facia (dark brown).
  • 5 vented soffits (dark brown).
  • 110' soffit J (dark brown).

The garage is done, and we have the house water proofed and ready for tomorrow. 100_1572 100_1573 100_1574 100_1575 100_1578 100_1580 100_1581 100_1582 100_1583 Roof Report, August 29, 2011: We showed up in the morning and started ripping the low slope, then I found a couple step flashings too short. The valley is double layered but we got it removed and water proofed for the next day. Roof Report, August 30, 2011: Today I went to the site and started roofing while also helping the crew clean up some garbage in the morning. The bin guy couldn’t make it back today so I didn’t get as much garbage removed as I would have liked. I got most of the back of the house done but I had to use the old led plumbing boot as the one I got was an inch too small. 100_1591 100_1592 100_1594 100_1595 100_1596 100_1597 100_1598 Roof Report, September 1, 2011: I removed the old roof from the front side of the house (the steep dormer and the top roof). I found two squirrel holes under the valley and in the fascia. I covered them with step and no squirrels are getting in now. Were all ready to go tomorrow weather permitting. 100_1609 100_1610 100_1611 100_1612 100_1614 Roof Report, September 5, 2011: We went there Friday hoping to get the job done, in the morning I started ripping the steep parts with the crew. Rain hit at around one o clock or so but it only lasted for about a half hour. We got back to work and pushed as hard as we could. This site is now complete. 100_1619 100_1623 100_1625 100_1627 100_1629 100_1631 100_1632 100_1633 < End Report > CODE: 13109 Contact Us 24 Hour Emergency Roof Repair. Telephone: 1.403.873.7663.

Snow Removal and Roof Replacement in Edmonton AB, 2011

Below you will find a report and quotation for an ongoing commercial client in Edmonton, Alberta from our roofing repair crew. The first is a winter call for snow removal, the second is for a summer call inquiring after a roof replacement. More reports and photos will be posted as they become available Assessment, January 18 2011: Scupper drains on the north and south sides were blocked with ice (frozen drain pipe). I suggested to disconnect the pipe, clean the ice out of the scupper, and clean the snow from the roof. There are a lot of safe areas to throw snow from, so this should be an easy snow removal. Field Report, January 19 2011: We arrived at 8:30 am and removed approximately 6000 sq. ft. of snow from the flat roof. The ice from the two scupper drains was also cleaned and we applied ice melt. When the winter season was finished, the client called us back for a roof replacement quotation. Quotation, July 31 2011:

Grasslands Commercial EPDM Roof Repairs, July 2011

This commercial client required the GRS crew to apply EPDM cover strip on his rooftop. Additional minor repairs were completed on the AC unit on the building. The client was also presented with recommendations for future repairs. Roof Report, July 20, 2011: We went to Grasslands today and applied the EPDM cover strip to the drip edge making it fully sealed. There were two curbs with fans sitting on top that needed to be wrapped. This will prevent water from getting inside the building because there was only a piece of wood on top of the curbs which isn't a good enough seal. As for the large AC unit on the existing roof, because they didn't want to crane it off of the building when we started the job I had no choice but to wrap the curb and apply water block around the outer perimeter of the unit. It was however leaking where the water block was applied, the only reason I can think of why that happened was because it rained before the water block had fully dried. I did tell the client that all I can do to fix the issue is put more water block around it and if the problem persists that we will have to crane off the unit. That way I can add another piece of rubber and re-wrap the curb, tucking it underneath the unit which is how we would normally do it on any new curb. They are aware of this problem but they haven't decided how they are going to deal with it yet. Other than that everything else is sealed up and good to go.
IMG_0122
Since the client did not want the large AC unit craned off the roof, our technician had to wrap the curb and apply water block around the unit.
IMG_0123
We started the process by wrapping over the curb that the units were sitting on.
IMG_0125
Once curbed, an EPDM cover strip was applied around the perimeter of the unit.
IMG_0126
Cover strips were also applied around the wall connections of the building, with emphasis on the corners and seams which intersected with the fixture. Once adhered, water block was applied.

Edmonton Residential Roof Deck Waterproofing Inspection, July 2011

This client required a quotation for various waterproofing options to fix a leaking deck. Our crew was dispatched to provide an inspection and to determine where the leak was coming from. Inspection, July 27, 2011: I arrived on-site and the client took me to the garage and showed me where water was still dripping down from yesterday’s rain. They have the drywall and insulation stripped in the area where the drain comes down from the flat roof. I set my ladder up on the cross beam that runs across the garage. I was facing the entrance to the house. The floor joist runs just to the right of the roof drain, it is spliced on the cross beam that I had my ladder leaned up against and it appeared to be soaked between the two joists on the splice. The splice and also a very short piece of 2x4 about 2” long appears to be screwed to the deck from above. When I stuck my finger between the 2x4 and the joist it was saturated, this is the area where the water is coming in. It is within a foot from the drain area but the drain or drain pipe itself was not wet at all after running a water hose down it to test it. The client did say that the water does not come through right away when it begins to rain so the leak may not be in the immediate area but I am convinced it is coming from the flat roof. I inspected the shake roof surrounding the flat roof but didn’t find anything that I felt would be the problem.
100_1209
The inspection of the drywall and insulation revealed that the entire assembly was saturated with water from leaks.
100_1210
The technician's ladder was setup on the crossbeams across the garage. From this view, our technician was able to inspect the floor joist that ran just to the right of the roof drain.
100_1212
After inspecting the flat section of the client's roof, the technician could not easily surmise what was causing water ingress.

Residential Roof Window Leaks in Edmonton AB, July 2011

Below you will find an assessment and photo journal from the Edmonton roofing repair crew. The client had called in about leaks coming through his roof window caused by a poor installation. The system was only a year old. Work Order, July 10 2011: There is a roof window in my pool area that is leaking. The cedar shakes were replaced, but the problem subsists. Assessment, July 14 2011: Note that  the client had the back side of his roof replaced last year. The problem area was a roof window 40 ft. wide. There is only a three-quarter inch. curb. Instead of building it up with a row of shakes and overlapping the top, the previous roofers tries to flash it. It is now leaking but they will not come back to take care of it. My solution is tearing up three to four rows from the top of the roof window, building it up (BUR) with a row of shakes, flashing over top with valley metal, and sealing it to the curb. 36 in. Ice & Water up from the flashing, and then 18 in. felt will be used for protection. 35 ft. of ridge capping will also be replaced. Quotation, July 14 2011:
  • Remove three to four rows of shakes above the sky window.
  • Install a row of shakes to the full length of the sky window to get the roof up to curb-level.
  • Install flashing from roof deck to curb and seal to curb.
  • Install 36 in. Ice & Water shield from roof deck onto flashing.
  • Reinstall 18 in. roofing felt.
  • Reinstall three to four rows of heavy cedar shakes.
Repair Photos, July 18 2011:
100_1220
We began by removing four levels of shake from the sky window.
100_1214
The aim of the tear-off was to expose the underlayment.
100_1216

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.

For the first unit, we removed the base flashing and applied liquid rubber around all of the seams.

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.

The same process was repeated for the second unit. We completed removed the old flashing to expose the base.

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.

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.
