Edmonton Residential EPDM Roof Installation, May 2011

The project began with the client contacting us for an estimate and overview of possible roof replacement options. Our project manager provided a quotation with various options and the decision was made to have an EPDM roof installed. After speaking with the client and inspecting the rooftop it became clear that there would be lots of work required. The old metal roof needed to be ripped off, the tar and gravel needed to be removed, and any deficiencies in the substrate fixed. The client also indicated that he would like bitumen torch-on applied.

Missing screws, dents, small holes, and bending were among some of the problems we found on the metal ridge cap.
SG1S2977
The seams along the ridge cap here can be seen curling away from the roof surface. In this case, the metal is no longer water-shedding, but has created a direct avenue for water entry into the building.
SG1S2979
Closeup of deficient seams. Several pockets were forming at the seams, whereby adjacent metal panels began expanding upwards.
SG1S2984
Furthermore, various rooftop appliances were deficient. In the case of this plumbing boot, raised seams around its base created a leak entry point. Spot repairs using liquid rubber can also be seen, which were also past their life cycle.
SG1S2982
This is a closeup of a spot repair that had been performed around the base of a gas appliance. The spudding had begun cracking in some places, creating small holes and tears.
SG1S2983
We removed one section of the metal roof and placed a tarp over it. Our crew returned the next day to perform a full roof replacement.
SG1S2985
Flashing around the perimeter had also been curling up and required replacement.
SG1S2986
Our inspection also entailed checking around the gutters and downspouts to ensure that all drainage systems were in proper order. In this case, the staining at the edge of the roof is a sign that water had been shedding towards the gutter.
  The crew returned to the site after the initial inspection and began removing the old roof completely. Fiberboard and EPDM were installed but the crew had to return in the morning to finish the detailing because of strong winds. The roof is now water tight. < End Report > CODE: 6108 Contact Us Call our 24 hour emergency roof repair at 1.780.424.7663. Mail to: 3428 99 Street NW Edmonton, Alberta T6E-5X5.

Edmonton Full Residential Shingle Re-Roof, May 2011

This residential client required a full re-shingling of their roof because of several issues that were discovered upon inspection by our team. The inspection revealed that the shingles were beyond their useful life expectancy as well as a possible issue with the ventilation system. Inspection Notes
  • 3 Tab shingles are beyond useful life expectancy.
  • Moderate slope and intermediate difficulty.
  • Chimney flashing needs detailing.
  • Front drive is appropriate for bin.
  • There is access for a crane load of shingles.
  • The house is a candidate for a premium shingle product as roof shows to street view.
  • Attic inspection required prior to installation as ventilation likely needs correction (exhaust seems too low).

We started our inspection from the top-down. All rooftop appliances, the ridge cap, valleys, and gutter systems were checked for deficiencies.
Photo on 2011-05-09 at 14.23 #3
The roof did not have valley flashing, and some of the shingles on this section showed early signs of fish mouthing. As can be seen in the valley, there were also exposed pockets formed by improper spacing between the shingles.

The shingles also showed signs of heavy weather damage. Over time, the asphalt on shingles wears away. This is usually caused by hail or heavy rain.
Photo on 2011-05-09 at 14.23
There were some signs of spot repairs that had previously been attempted on weather-damaged shingles.

Finally, we looked for damage around each of the rooftop appliances, including plumbing boots and ventilation units.

Edmonton Residential Flat Roof Inspection, May 2011

The original inquiry started with the client needing suggestions on what to do for a patio cover. However an inspection of the site led to the discovery of additional concerns, the main one being ice damming on the rooftop. It became apparent that the roof was in very poor condition and should ideally be replaced. Once on-site the crew noticed an unusually large amount of ice damming which prompted them to go onto the roof and take a closer look. The client also came up on the roof and was shocked by its condition. Ice damming had taken away almost all of the gravel in the areas affected and the underlying tar was cracked as well. Other areas of the roof show significant wear. Upon querying the client, the crew discovered the age of the roof to be approximately 30 years old. The client also indicated that she might be interested in replacing the siding and eavestroughing as well.
1
Ice damming had caused significant amounts of gravel to expose parts of the roof. There were tears in the tar surface around the edges of the roof, as well as around some rooftop appliances. We also inspected the flashing around the base of the chimneys and noted signs of significant wear.
4
The flashing around the chimney was rusting, and did not extend all the way down to the roof surface. Much of the gravel around its base was also missing. We found tears along the chimney-roof connection. The perimeter flashing was in much worse shape, with sections completely bent away from the roof. Finally, we inspected the drains and plumbing boots. Some of the surface tar had small holes around the drains.
3
After completing the inspection, we took measurements of all flashing components as part of the quotation we would later provide to the client for a roof replacement.
2
Finally, we inspected all penetrations, downspouts, and gutters. We noted pockets formed between the roof surface and the edge flashing. As the ice dams had melted, water was entering the building envelope through them. Furthermore, one section of the roof used a metal sheet, which was past its life cycle; significant rusting and holes were found throughout the metal. In general, most of the roof had also been exposed over a long period due to the missing gravel not being replaced.
The following email was sent to the client by our project manager so that she could better understand the replacement and recovery options:
With respect to the house roof replacement please find attached the pricing you requested. The documentation / links detail our Workmanship Guarantee, System Options and Methods, 2011 Schedule Availability, Links to Manufacturers, our Project Portfolio and References. 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. The Roof Recovery has our crew scraping the gravel off, taking the old membrane and soaked insulation off (only as required) and then attaching a fibre board and then putting a new roof over top (SBS, Mop On, EPDM, TPO, or PVC per quote). Typically a roof recovery is what is done. A roof recovery is less intrusive to our client, 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 to completely remove the old system down to the sheathing we can accommodate and the pricing is included also. Additionally, there are a number of different membranes available in today's market, which I've detailed in the quote. Essentially, it usually comes down to 1) a traditional 4ply mop on (BUR), 2) a 2ply SBS torch down, or 3) a 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. Single ply systems are typically what we install more and more - we install all system types, but I would encourage you to consider the life-cycle costing and maintenance / repair benefits of a single ply system prior to ordering. Have a read and let us know what you think - I'm sure you will have questions. Thanks for the opportunity to quote - it is appreciated.

Edmonton Roof Flashing Repair, May 2011

The report below covers an inspection and repair to a client's residential building. Their failing low-slope roof required some re-flashing, but upon first inspection it was clear that there would be more work to carry out beyond this simple job. Inquiry Received: May, 2011 The client reached out to us to provide a quote for re-roofing their low-slope residence. We sent out a technician to inspect the roofing system, and they provided the following notes. Inspection: May 7, 2011 After inspecting the roofing system and taking photos of the area, the technician carrying out the inspection send in some note about the potential project, and discussed options for replacement.
  1. The roof (overall) is in poor condition.
  2. Apart from the usual blistering and gravel wear, there are two locations where cracks have appeared.
  3. The cracks themselves are very deep, so much so that one could touch the joists below with a finger.
  4. There was what appeared to be a small hole found in one of the cracks, but when it was traced out it was found to be about a foot long. Another hole was found to similar result. Unfortunately, there's no way to tell how many such deficiencies exist.
  5. A number of on-roof drains are clogged and unusable. Will need attending to.

There are splits in the roof from top to bottom and across the top of the roof. It looks like the skin and board will need to be removed, so the client would need to be made aware of that once they returned home. As the metal is also unusable, dimensions will be taken and sent over to GRS' metal expert/journeyman for ordering new material. Roof Report: May 25, 2011 Inclement weather dogged the team as they loaded the materials onto the roof, but the rain got progressively worse. Unable to work in such conditions, the team contacted the client and explained the situation. They were very understanding and accepted the rescheduling for the following day. Roof Report: June 7, 2011 The shipment of metal came in, ready for installation. The team had it picked up and delivered onsite, then loaded it onto the roof. The metal has now been installed, sealed, and is otherwise complete.     CODE: 7824 Contact Us Call our 24 hour emergency roof repair at 1.780.424.7663.
