Roof Shingles Before and After: The Grandin Village Project Story

Recently we got a call from the property management company of some townhomes in St. Albert. The shingles on their roofs were only about 12-15 years old, but they already needed to be replaced. Asphalt shingles are the most common roofing material for homes in the Edmonton area, so you might think that you can just buy any kind of shingle and expect it to last a long time.

Unfortunately, that’s just not true. Shingles come in all different qualities and prices, and you get what you pay for. On the Grandin Village townhouses, the shingles were curling severely because of two main reasons:

1) They were shingled with low-quality, builder grade shingles. Builder grade shingles can be as much as half the price of a regular, good-quality shingle, but they are thinner and made with lower-quality materials.

2) The roofs had low slopes, meaning they weren’t very steep. In Edmonton, it’s better to have a steeper roof because snow and ice can easily collect on flat or low-sloped roofs.

Ice and Snow Can Shorten the Life of Your Roof

When snow melts, water gets in and underneath shingles. If that water freezes again, (which happens frequently in the spring) the ice expands and makes the shingles pop up, damaging their waterproof seal. Ice also makes the ceramic granules on shingles fall off.

Those granules are very important! They protect your roof by shielding the asphalt from UV rays, which will disintegrate asphalt and the fibreglass mat underneath it. The sun can also pull the oil in the asphalt to the surface of the shingle, causing it to become brittle and crack and curl. These shingles were organic and made of felt and tar paper, so they got wet, then they curled when they dried. On the low-sloped gable Grandin Village roofs, there is no shade from the sun, just constant exposure.

Re-roofing 20,000 Square Feet of Roof

Luckily the boards underneath the shingles were in good condition, so this re-roof project was just a matter of scraping off the old shingles and adding new ones.

A house roof will take a day or two, but a normal house roof is usually only about 3000 square feet. Those three townhouses had 20,000 square feet of roof, so it took about two weeks to finish. If you’re wondering how big your roof is, you can use a Roofing Calculator to figure it out.

Starting the Re-roofing Project

Before we started on the project, we sent someone out to inspect the roof and draw up a quote. When the new shingles were chosen and the date was set, we had the property management company sign off on it so we could begin work.

Below is an image of the roof before we started working on it.

Starting work involves tearing off the old roofing and underlay in sections that we can finish in a day. On these roofs, we also changed out the old vents for better ones that would perform better and last a long time. We featured the Grandin Village Townhomes in an article we wrote about roofing ventilation, and you can read it here.

Before we lay new shingles, we first need to prep the roof. This includes putting down drip edge protection, then an underlayment of felt and an ice and water shield around the eaves. In this case we put down two layers of felt underlayment and two rows of ice and water shield because of the low slope of the roof. Once we had the proper base layers installed, it was time for the shingles to go on.

Here is a breakdown of the materials we used:

  • Nails and nail guns
  • 36 inch Ice and water guard
  • Drip edge protection
  • Roof rippers to get the shingles off
  • 15lb felt paper
  • shingles
  • vents

We Use High-Quality Shingles for Long-Lasting Roofs

We do high-quality work with high-quality materials because we know that they will last a long time and our customers will love the results. For this project we used the Malarkey Legacy in the colour Sienna Blend, and the end result was a great looking roof that will easily last 20+ years.


The condo board was happy with the colour and the quality of the shingles. They were also happy with the amount of time it took us. There hasn’t been a need for any repairs at all and best yet, they called us back to do more roofing work for them!

Summer Project: Half Moon Lake Re-roofing


This summer we’re working on some homes in Half Moon Lake, which is hamlet about 35 minutes east of Edmonton in Strathcona County. There are only about 100 homes there and most of them are right on the edge of Half Moon Lake. The area is beautiful. The homes are surrounded by trees and visited by wildlife all the time. It’s a peaceful community with some beautiful homes where people get to enjoy lake life while still being close enough to town to be able to pop in whenever they need to.

We have some good friends in that neighbourhood, so when a few of the homeowners in the area were thinking that this was going to be the year to get their roofs redone, they gave us a call.

Of all the homes we’re doing in Half Moon Lake this summer, a few of them had smaller roofs that were all about 15 to 25 years old, which is a long lifespan for a roof, especially one with shingles.

Shingles generally only last about 15-20 years before they need to be replaced, so many of the homes already had leaks despite previous repairs. It was time for full re-roofing on all of the homes we inspected.

Re-roofing a Large Home in Half Moon Lake

The largest house we worked on had big, old cedar shake roofing material covering their roof that was at least 30 years old and falling apart. They were seeing leaks on the inside of the house–around the chimney and on the ceiling–and were ready to get their roof redone.

We went out to do an inspection and give them a quote, which included a recommendation for a great shingle product that would be ideal for their house. We found that it wasn’t worth their money to keep repairing their roof. It would actually improve the value of their home to have a modern, sharp-looking roof that was going to last a long time.

Malarkey Windsor Shingles for a Long-Lasting, Great-Looking New Roof

Asphalt shingles aren’t really known for their long-lasting abilities, but Malarkey Windsor shingles are different. They are top-of-the-line in the shingle world and they have a unique design. They are durable, heavy shingles that are made with an SBS rubber that helps them last a lot longer.

Malarkey Windsor shingles also have a great warranty that includes 15 years of full coverage for any manufacturer defects, labour, and materials.

We gave our clients a couple options, but they went with the Malarkey shingle. We went over the costs together and they ended up being really impressed with the quote we gave them. We started the work soon after the papers were signed.

Because the shingles are relatively new on the market, a representative from Malarkey came out to explain how the shingles worked. He also gave us tips about installation, and made sure the end result was the best possible, which was hugely beneficial for both for the crew and the homeowner.

Even though we were using a special shingle product, our tools for the job were the same as most of our other roofing projects.

We used

  • 44 inch ice and water guard
  • Synthetic underlay
  • Drip Edge (a piece of galvanized metal that helps guide water into the eaves)
  • Nail Gun
  • Ridge vent that goes along the peak of the roof

We ended up doing three homes in the early part of the summer, and we’re currently working on a couple more. When we finished the big house, the Malarkey shingles looked amazing. Our clients  were very happy. They loved the way it looked and how it worked, which was a huge compliment coming from them because one of them works in interior design!

When the roof was done, we went out with a drone to take pictures to share the sharp new roof with our friends and fans on social media.

Steve’s Flat Farmhouse Roof Repair

Steve’s home is located northwest of Edmonton, Alberta just past Morinville. He owns farmhouse with a tar and gravel roof that was at least 25 years old, which is a decent lifespan for that type of roof.

It wasn’t just that the roof was old that made Steve want to have his roof looked at. Stains had formed on the ceiling from leaks under the roof. When Steve went up on his roof to take a look, he noticed that the whole roof looked very weathered, there were blisters on the roof, and when he went to walk on it, he actually fell right through!

Luckily Steve didn’t suffer any major injuries from falling through his roof, but that’s not always the case. Some cuts on the feet and legs are minor compared to an English scaffolder who fell through a roof and suffered “life-changing injuries.” (You can find the full story here.)

How To Tell If You Need Roof Repairs

The weakness of Steve’s roof was a clear sign that it needed fixing, but sometimes it’s not as easy to tell. Here are some symptoms, other than falling through, that may mean you need to repair/replace your tar and gravel roof:

  • Bare patches of roofing felt or tar
  • Cracks in the tar of the bare patches
  • Speckling from mold or mildew on the ceiling inside your house
  • Water stains
  • Holes or blisters

After inspecting the roof, we recommended he do a re-roof on the second storey of his home, and some patches on the first storey.

We can’t guarantee patching, but we have a 5-year workmanship guarantee on our work and a 15-year limited residential warranty on a new roof, so we agreed on a new SBS Roofing System for the second storey section of the roof where it was more damaged and some patching on the second storey.

Doing the Roof Repair Job

With the agreement written out and signed, we scheduled a time to go out and fix up Steve’s roof. The job took a crew of four of our skilled roofers: a journeyman, an apprentice, and two labourers.

As experienced roofing professionals, even though we were working with both SBS and tar and gravel, this wasn’t an unusual job, and it only took about a week to do the repairs and the re-roofing.

We used

  • Roof Rippers
  • Hammers and nails
  • Torches
  • Torch-down T-180-cap for second ply
  • 1/2 inch FR board base sheet

Once the job is done we like to stay in contact with our clients and come back periodically to inspect the roof. This is a good idea for any roof, not just one that was recently repaired because regular maintenance can really extend the life of your roof.

Wondering what to do when you have a Leaking Roof?

Roof Leaking?

Dave is a client of ours who owns a flat-roofed home in Sherwood Park, Alberta. He noticed that his roof had been leaking for a few months when he got in contact with us. Whenever it rained, he saw water leaking through the soffit and behind the eaves troughs of his tar and gravel roof. On the inside, his ceilings were developing water stains. Dave wanted to get the problem fixed, so he had us come in to do an inspection and schedule a repair.

So, what was wrong with Dave’s roof?

When we got there, we found that a whole corner of the roof was rotten, which we could tell because it was soft to walk on. A roof will only be soft for two reasons:

  1. It’s rotten – likely from all of the water accumulation or
  2. It’s made with paper-backed, rigid fiberglass insulation. Stiff fiberglass insulation isn’t necessarily soft to walk on, but it’s spongy. It’s also only used on commercial buildings, so since Dave’s roof was on his home, this wasn’t the reason for the leaks.

The rot had created holes in the roof that were allowing water to leak and rot the trusses and the wood deck. It had compromised the insulation and there was also damage to the fascia board.

We told Dave of our inspection results and told him how we could fix it and that we would get back to him with a quote.

Once at the office, we drew up a quote and sent it to Dave, along with our WCB and liability insurance numbers. Dave sent back a couple questions he had about what we do with the rotten parts and how we were going to do the repairs (Read our FAQ for answers to his questions and more.) We cleared up everything for him and got together to sign the contract.

The Day of the Re-roofing

On the day we scheduled the re-roofing to be done, Dave was there to answer any questions we had as we worked, and generally just be around to watch the job. It’s not essential for you to be home during the job, but it’s up to you.

We brought a crew of 5 to do the roof: A couple labourers, a few apprentices, and a journeyman/foreman. Meet some of the guys on our crew.

Since this was a tar and gravel roof, we used the usual roster of equipment:

  • Roof Rippers
  • Table saw
  • Hammers
  • Nails
  • Torches
  • Drills

Plus additional woodworking tools like a table saw and a skill saw.

First we took off the tar and gravel. It turns out it was at least 25 years old, which is a fair amount of years for a tar & gravel roof. When the roof was cleared of all the old material, we put in an SBS roofing system, which is a little cleaner and modern than tar & gravel and we added some rigid insulation.

The end result is a roof that is maintenance free for 10 to 20 years, but it’s always good to check on your flat roof. With some proactive maintenance, this type of roof will last at least 25-30 years.

Throughout the installation, the journeyman and project manager inspect the job to make sure everything is done according to code. When the job was finished, we reviewed it with Dave, who was very happy with his new roof.
