Roof Repair 101 – Steps to Contract an Edmonton Roofer

Roof Repair Edmonton, Stony Plain, Spruce Grove, Fort Saskatchewan, St Albert, Sherwood Park, Leduc, Nisku, Beaumont, Edson, Drayton Valley, Camrose, Wetaskiwin and many more rural areas and towns in Central and Northern Alberta. [Note to reader: This article is a local Edmonton, Alberta adaptation of an article I originally wrote and published to our national roof repair blog. I have adapted the article specific to roof repairs in Edmonton considering the local weather and climate and how our local climate affects roofing material, install, and venting decisions.]

How to Contract a Roofer for Roofing Repair in Edmonton, Alberta.

A little about my roofing background first. I began my roofing career in Alberta about ten years ago. Over the last ten years I have managed crews on commercial and residential for flat roofing, steep pitch and industrial metal roofing from Vancouver to Edmonton, Calgary, Saskatoon, Regina to Toronto. After managing roofers on thousands of roof repairs and various types of work sites all over Canada I can confidently provide you with the key steps of preparation you should engage before hiring your roofing contractor of choice. Hiring an Edmonton roofer for roof repair requires the following steps: Is Your Leaky Edmonton Roofing Repair a Real Emergency or Can it Wait Until the Next Day? The only reason you want to call a roof repair contractor in the evening or on weekends is if it is a real serious emergency. Emergency evening and weekend roof repairs can be expensive and in many instances the leak can't be stopped anyway in the dark or when the roof is too wet. Most roof leaks can wait to be assessed until the next day. But of course, some cannot. We respond to emergency roof repairs for public buildings like commercial businesses (such as restaurants and retail stores), for industrial and manufacturing facilities, for buildings that have lots of computer servers and equipment and that sort of thing. Specific to the Edmonton area we attend to many emergency roofing calls for ice damming, snow loads, and flash rain storms. Roof ice dams can cause a risk to the public if the ice dams are causing ice to fall to the sidewalk for example. Also ice dams can destroy roof systems and cause significant leaks. Snow loads, if excessive, can cause flat roofs and low slope metal roofing to collapse. And flash rain storms can cause flat roofs to collapse (if drains are plugged) and high winds can topple trees on to roofs and lift whole sections of pitched and flat roofing systems. During the roof snow load emergency events in Edmonton the winter of 2011 we responded to many collapsed roofs and buildings that were about to collapse from snow and ice loads.

What Type of Building is Your Roof On? Commercial, Residential, Industrial or Institutional? The reason the type of building is important is because not all roofing contractors are experienced with the roof membranes or materials that are commonly used on different types of buildings. Also, and of serious importance, not all roofing contractors and their roofers are familiar with the fine details of working in an industrial environment (for example). Choosing a roofing company that is set up for industrial work (for example) or whatever type of building you have will go a long way to achieving a smooth and successful work completion.
Commercial Roofing
Installing a commercial roof - be sure to hire a roofing company familiar with your type of building.
Is Your Roof Low Slope Metal, a Flat Roof or Steep Pitch Residential? After you have established if the work is an emergency or not, you have identified what type of building they will be working on, then the next step is to determine what category of roof type they will be fixing. The three main types or categories of roof systems are steep slope (such as shingles, cedar, tile, metal etc), low slope membranes or low slope industrial or commercial metal roofs. Identifying which category your system falls in to will really help you with communicating with and identifying contractors that fix roofing with that specific type of work.
EPDM, Roof
Inspecting an EPDM Ballast Roof for pricing preparation.
You Need to Know What Kind of Material is on Your Roof. If there is a place most homeowners or business owners (even professional buyers) make a mistake when choosing and contracting a roofing company is at this step. You want to know specifically what kind of roof material you have because you need to confirm and verify that the company you are hiring is an expert with that specific material. Not all low slope roofing materials are alike. The same applies to steep pitch and standing seam metal roof systems. Flat roof membranes installed in the Edmonton area are typically one of the following: Tar and Gravel (Built up - the one with small pea gravel on top - not river rock size FYI, if larger like river rock that means it is ballasted), SBS Modified (Torch On - many people describe it as rolls with shingle type material on top - granules - it comes in many colors but is most often grey), TPO (Thermal Plastic - it's kind of like a rain coat material and typically white but not always), PVC (Poly Vinyl - it looks like TPO), EPDM (rubber membrane rolls typically black), Liquid Applied Rubberized Asphalt, or a coating such as Liquid Rubber. Steep pitch roofs are typically: shingles, cedar, pine, metal shingles, metal panels (standing seam or not), concrete or clay tile, composite plastic tile, rubber tile or many other. Low slope metal roofs are normally found on commercial and especially industrial buildings. They are typically one of three types or categories... agricultural grade (non locking with exposed fasteners), snap lock type or standing seam of one form or another. The above are simplified lists of available roofing material types but it should give you an idea of how to start the conversation with each company you call if you don't already know specifically what type of material is on your roof.
Roof Hatch, Curb, Roof, Tar

Your Goal Should be to get Pricing for All Options Available for Your Specific Type of Roof Material (be it for temporary fixes, maintenance, replacement or a recover). At this point in your search for the right roofer, you want to task any companies pricing the work to provide you all the possible options for fixing the roof or replacement for your specific material  and building type. Request all options available in writing. Get details. Get pricing for each method and type of material. And most importantly, get the pros and cons of repairing or replacing your system for each method. Even if you are simply getting pricing for renovation work such as drains, curbs, metal parapet flashing, mechanical repairs or a roof hatch it is important to get options for pricing. Here's an example.... EPDM can be installed as fully adhered, mechanically fastened and ballasted. It can be inverted or not. The membrane itself typically comes in 45 mil and 60 mil thickness. The insulation can be sloped or not. The insulation can be different types of insulation and different manufacturers, as with the vapor barrier. Different systems and products have different warranties. And contractors have different workmanship guarantees. So in this example, not all EPDM roofs are equal - it depends on a number of factors. Just like a car is not a car or an SUV is not the same as all SUV's. A flat roof is custom designed and installed for your building, objectives and climate - at least it should be.
Knowing what I know about roofing and assuming I live in Edmonton, here are some of the specific pitfalls I would avoid.
  • Spray Foam (SPF) Roofing Installed Over an Existing Tar and Gravel Roof (or metal or whatever). The reason you need to be cautious about this is that many of the spray foam contractors are not from the roofing industry and many do not understand generally acceptable roofing principles (roofing is a red seal trade). We install spray foam as an option for our customers also, but we know that to do the job right costs real money - there is no shortcut. So the idea that spray foam (SPF) is cheaper than other membrane methods is simply not true (if done in accordance to acceptable standards for our climate). Spray foam can be a fantastic product if done correctly - if the right materials are used and the right thickness of coating over the spray foam is applied.
  • Metal Roofing Will Last Forever. Well, maybe it will last your lifetime. But did you check to see if it may leak? Actually, what it does is condensate (science is on my side there). So if it is a low slope or even moderate slope I would think real hard before installing a metal system. You will want to be sure it is as steep as possible, that the panels are locked properly, and that the installer knows what he or she is doing because there is no fixing a bad metal roof install. Also, don't fall in to the trap of the sales pitch from the manufacturer that says you need to buy their metal panel package and then get an installer - often big mistake. I take calls weekly with people that have bought a standing seam metal panel package and no qualified installer. A qualified standing seam metal crew worth any amount of weight is booked at least many months in advance - which often leaves people stranded if you want your standing seam metal installed this year if you didn't book a crew.
  • Edmonton is Cold - Use Caution. Expansion and contraction with flat roof systems is massive in Edmonton. If you have spray foam installed over a flat roof that has a coating that isn't installed properly (or not thick enough) the coating will crack and peel and water will get in and run between the spray foam and the original roof. You may then have to rip up the old system you covered and the new spray foam system and start all over. Or, if you are coating metal remember that we have more cold days than hot. Do you really think a white or reflective coating in Edmonton can achieve a net efficiency benefit to your building? Highly improbable.
  • Spot Repairs on Low Slope Metal Roofs Should Work? No. Very unlikely. You need to either replace it or do a coating over the whole roof. Why? Because water runs and it will find the path of least resistance. You can try spot repairs but don't be surprised if they don't work is all I'm trying to say.
  • With Shingles Spend the Money on Ice and Water Membrane and Proper Ventilation. Edmonton ice damming on roofs can destroy a home. Why not put a little more money in to your work and do it properly and protect your home? Ice and water should be at least one row but preferably two rows at the eaves. Ice and water shield membrane should also be in the valleys. And ventilation should be calculated and installed properly allowing for proper intake at the soffits and exhaust at the ridge. Ridge vents are the best for this.
  • Flat Roof Deck Membranes. Be cautious to get a good rooftop patio membrane that is suitable for use for foot traffic and as a low slope waterproofing membrane over a heated living space. Dectec is an excellent product for this because you do not need to add a floating deck on top of the roof membrane. Torch on is also good but it has granules so it isn't nice to walk on in bare feet so people end up having to construct a deck on top of the membrane which can cause problems.
  • Should my Low Slope Roof Membrane be White or Black? Unequivocally it should be black in Edmonton. DO NOT buy in to the marketing coming out of the United States - it does not apply to colder climates like Edmonton, Alberta. You do not want to reflect the heat from the building in 99 out of 100 instances. There are more cold days than warm days in Edmonton. Also, white roof membranes are proven to condensate in cold climates (Google search the topic).
  • Know What You Are Buying. We see this all the time. We quote a job and the customer gets two other quotes. The customer comes back to us during the quoting process and says, "but your price is 30% more, boy you guys are expensive". Well, not necessarily - in fact, I know we're not more expensive because the quality contractor that includes a specification for workmanship will last is actually more often than not operating at a lower margin but investing in long term success - in other words, less return trips. So with lower return service trips the quality contractor operating at a lower margin to start with, is actually doing better over the long run. Check the specifications closely - ask us to help and you will find that good value is always found with the quality contractor - always. You just have to discover why.
I will stop there because this article could be a book in length if I continue.

What are Your Main Objectives With Hiring a Roofing Contractor to do the Work? Your objectives are very important because the solutions for those objectives will determine the direction of discussions and quoting process. The scope of work for your project is directly linked to your objectives (or should be anyway). You need to communicate those objectives to your roofing contractor. It may be that you are keeping the building as a long term investment or not. Or it may be that you are looking for the least costly way just to get you through for the time being. Or, in many instances we are called for mortgage requirements or insurance purposes. Whatever it is, be sure it is clear because that will direct your contractor in the process of designing a specification that is appropriate to your needs.

Due Diligence Checking out residential contractors is really important if they haven't been around for a number of years because it is so easy to get a ladder, hammer and call yourself a contractor. The best advice I can give there is that if they have been around five years or more you are likely in good hands. Be cautious of the review sites because they can be "gamed". Just because contractor A has 200 good reviews and contractor B has none doesn't mean a thing. Contractor B may be booked all the time and couldn't be bothered. On the industrial and commercial side of the industry I wouldn't be as concerned. Commercial contractors have to invest significant money and run larger overheads etc. If a commercial contractor has been around for more than five years chances are they will be around for decades and you are in good hands more often than not. It is very unusual for us to run in to a commercial contractor that has been around for years that isn't doing right by their customer.

Edmonton PVC Narrow Roof Repair, September 2015, Edmonton

This client had GRS come out to carry out some repairs on the narrow flat edge around their home. The technicians affixed the PVC metal to the surface, welded it into place, and sealed everything before leaving the site complete. Roof Report: September 25, 2015 The team went out to the client's site for 8:00am and carried out the hazard assessment before making their way up to the roof. They started down by fastening PVC metal, and one of the crew members worked behind the other to clean it off with splice wash. The third crew member, working ahead of the two others, was cutting the PVC membrane into 6" strips. By 11:00am, they had finished with the metal work and started welding down the strips. Half an hour later the team left for lunch and got some caulking from a local store. Upon their return, one of the crew continued with welding, while the other two caulked around the site and shored up the watertight seals. By 3:30pm, they got the deck rails welded into place and completed the job. All in, 128' of PVC metal was fastened down, and 135' of 6" x 5' strips were welded into place. The job site is now complete, and the technicians departed without any issues.
WP_20150925_10_38_29_Pro
Our scope involved installing PVC metal to narrow flat roofing which ran the perimeter of the house.
WP_20150925_10_38_35_Pro
The metal was fastened by one crew member, followed by a splice wash application by another. Leading this process, a third technician cut and laid down 6" strips of PVC, which was welded on.
WP_20150925_10_38_59_Pro
The original roofing assembly had missing screws throughout the flashing, and blisters in the membrane.
WP_20150925_15_17_53_Pro
Many of the seams were also left exposed.
WP_20150925_15_21_46_Pro
After dealing with the new PVC installation, we began securing new pieces of flashing around the perimeter of the roof. Initially, there had been raised sections which were curling away from the assembly.
WP_20150925_15_18_42_Pro
Our inspection also uncovered some exposed screws and penetrations requiring new coatings around the base.

Flat Roof Repair Edmonton – Gum Box. June 10, 2015.

Article: 2 Ply SBS Torch-On Low Slope Roof "Gum Box" Repair on Commercial Roof in Edmonton Alberta.

"Plastic pan - also called pitch pan, pitch pocket, gum box, these comprise a flanged collar placed around items that project through the roof system; the flange is properly set into the roof membrane and the pan is well filled with plastic cement; these pans are a constant source of trouble and should only be used when no other solution can be found." Source: Red Seal Roofer Program Website. February 13, 2015: Journeyman Roofer Attends for Roof Inspection.  Address 11754 170 Street Edmonton, Alberta.
The client is experiencing a small leak 15 feet in front of the front doors around an electrical conduit penetration in the roof.
The electrical conduit is two feet from the roof edge which is the highest point on the roof as the drains are in the center. I believe the leak could be leaking around the gum box which is starting to crack or where the stack is fastened to the roof. I believe the water is getting in through those holes and running back into the system.
To fix this problem we would need to first put a gum patch on the gum box and tighten up the bolts on the bracket that holds the conduit and seal around it with some good caulking.
Man hours 3 - 6 total with drive time and inspection time. Material 1 - 3 gal pail of gum. 2 tubes of tremco chalking.
Roof measurements 130 ft x 160 ft with two drain and 13 penetrations. The roof is approximately 10 years old and in good shape.

  February 21, 2015: Crew Arrives On Site To Complete Repairs. This morning we stopped by to confirm were the problem area was and that we had everything for the job.
Once we got back to site and went up to the roof I could tell that the water was coming in from the gum box.  A couple of things caused the failure, first that the steel pipe had moved slightly from being pulled by the weight of the wire hanging and that the crew that installed the roof only filled the gum box up 1/4 of the top with gum and had 3 inches of bat insulation filler.  Over time the gum began to dry and crack and settle allowing water to pond inside the gum box and leak through.
So we removed the gum out of the gum box and some of the insulation and filled 3/4 of the gum box with pour-able sealer, a permanent repair for the problem.  As a precaution, we also added a bead of lap sealant around the base of the gum box so that no water could pond there and installed a bead of high quality caulking around the metal support which had bolts going right through the parapet wall with no sealer.
Materials used: I tube of tremco caulking. 1 tube of lap sealant. 1 package of pour-able sealer.

EPDM Flat Roof and Vent Repair, June 4 2015

Article: EPDM Commercial Flat Roof Repair in Edmonton, Alberta. Roof Vent Exhaust Installation.

Flat Roof Repair Edmonton - EPDM - Roof Vent (Jack) Installation. The short site report below is the flashing in of a roof vent retro-fit (or roof jack as some refer to them as) to an EPDM commercial roof. Our client is an HVAC contractor that regularly calls on us to roof in retro-fits for flat roofs that have new air conditioners or some form of units installed. In many instances it is best practice to have any protrusion in a low slope roof to have a curb, in this instance a curb was not specified. Curbs are critical for roof skylights, sun tubes, and roof hatches. With other penetrations such as gum boxes, pipes and miscellaneous others it isn't as critical. For install detail instructions for various roof penetrations, curbs, etc visit the following link at Carlisle: https://www.carlislesyntec.com/search.aspx?mediatype=document&doctype=3&sort=doctype&category=96&categories=89,90,91,92,93,94,95 October 17, 2014: Crew Arrives To Complete Repairs. Flashing in of Rooftop Exhaust.  Site Location: 9503 12 Avenue SW Edmonton, Alberta.
This roof is a EPDM roof. They had two roof penetrations that needed to be roofed in properly. The roof was really dirty and covered in mud which took some time to clean. They used silicone to put a temporary seal around the units which we had to remove before flashing them in properly. Once we got them all clean we roofed the units in with form flash. The job is 100% complete. This was an hourly dispatch call-out plus material.
Materials used: 24 ft of 12 inch form flash. 1 can of primer. 1 bag of rags. 1 - 1 gallon can of EPDM splice wash. 2 tubes of EPDM lap seal.

PVC Roof Repair Edmonton, June 1, 2015.

Article: PVC Roof Repair Edmonton, Alberta. Flat Roof. Industrial. Single Ply Membrane. DecTec.

One material available to flat roof (low slope) owners is the single ply PVC roof membrane. The roof report below is specifically a DecTec type of PVC. PVC is an acronym for Poly Vinyl Chloride. PVC roofing is a single ply membrane. There are three different single ply roof membranes typically used in the market. One is PVC, the other is TPO (or thermal plastic polyolefin) and the other is EPDM (ethylene propylene diene terpolymer). PVC and TPO are welded with hot air welders (which would be different than using a torch when installing 2 ply torch-on SBS modified). EPDM seams are not welded using a hot air welder - EPDM is seamed with adhesive. PVC, TPO and EPDM are available in different colors but typically PVC and TPO are installed white and EPDM black. In all three instances (with PVC, TPO and EPDM) the roof membrane is attached to the roof assembly in one of three ways:
  1. Fully adhered. Fully adhering a roof membrane is the process of using a specialized adhesive to adhere the roof to the substrate or roof assembly. We typically install a residential home this way because it is lighter than ballast.
  2. Mechanically fastening means that the roofing contractor is installing the membrane with fasteners. Mechanically fastening a system is faster and less expensive than fully adhering it but we tend not to choose this method.
  3. And finally there are ballasted roof systems. A singly ply ballasted roof is typically one where the membrane is loose laid (seams are either welded or adhered) and then a smooth rock is then installed on top of the membrane to ballast it. Fully ballasted systems are less expensive and quicker to install than fully adhering the membrane, however, when possible we choose to fully adhere the system. After install service is more difficult and more costly with ballasted roofing because it takes considerable time to locate and repair leaks with ballast covering the membrane.
Visit our main website for an explanation for flat roofing membrane options and descriptions of each. Below is a short roof report from one of our single ply crews doing repair work for an industrial customer that calls us out regularly. February 19, 2015: Crew Arrives at Industrial Location to Complete Repairs to PVC Flat Roof. 
Site address: 1755 Railway Street Edmonton, AB.
Today we had to roof in one roof curb with DecTec PVC. The curb was 18 inches x 40 inches. We had to wrap it with PVC and weld in 4 corners. The only issue we had today was the amount of melting snow. We were repairing and working on a down slope portion of the roof. The melting water was continually running in to our repair of the membrane laps, but we managed to get the membrane dry enough to weld.

The reports below are for the original inspection of the roof and the repair work that the crews did on the condominium property. A front entry canopy required re-construction, there were scupper repairs, and some leaks around perimeter flashing on the built-up tar and gravel roof.

April 29, 2015: Roof Repair Crew Attends for First Day.
The following site is a condo building in Edmonton Alberta. We were sent here to complete three scopes of work. 1) Flat roof spot repairs around perimeter (remove flashing, repair, return flashing to roof). 2) Fix cracks on edge of scuppers to avoid future leaking scuppers. 3) Fix a canopy roof that was sagging on the front left side.
Scope # 1: Perimeter spot repairs on main tar and gravel flat roof.
We started the day with the toolbox meeting. Got set up on roof. The roofers started stripping metal flashing around the perimeter while I went and got supplies. We did two different scopes of work on the roof.
1st scope was patching around the perimeter of the cant flashing which consists of spraying down asphalt primer on area where patch is needed. Then putting one layer of mastic on top of the asphalt primer. We then put the green mesh on the layer of mastic. The next step in the process is to add one more layer of mastic on top of the green mesh and let it dry. Final is to re-install the roof flashing.

The second scope of work we completed was to fix the scuppers as they had cracks around the edge of them and they were leaking. To do this we screwed each side of the scupper tight against the cant metal. We then put on one layer of mastic on the cracks. We then added the green mesh to the first layer of mastic. Followed by one more layer of mastic on top of the green mesh. This is an alternate method to using open-flame torching.
