We had Mike and Jay replace our entire roof. They were timely and punctual-the estimated project start and completion was accurate. They worked six days a week to get the job done. They treated our home like it was their own. They were incredibly tidy. They are both knowledgeable and passionate about roofing and it actually became contagious throughout the project. We wouldn’t trust anyone else with our home!

I would like to give a 5 stars for this company who did a very good job for my roof replacement. my roof needs to be replaced entirely with the drainage system. the guys are very pro-active and they do know what should be done in a corret way. they notice what should be planned with the weather conditon during the work. they are pretty proffession and placed with better shingles without extra charging even. they are very care about the project than the ower, becasue they want to have a good performance of work. basically, you just need to out line the scope of works from the insurance compnay and leave all the rest to them. they will provide you a very delligent work. eventially, you dont need to worried about anything from the contruction side, they care more than the owner about the products. I am very happy to find those guys to do my roof works and hope they keep going on the great jobs !!

H&J Roofing replaced my garage roof with premium materials including all drip edges, underlay, sealants, and high quality shingles. Their service is not only professional but comes with quality craftsmanship in their installation. I want to use H&J for my next roof.

Couldn't be happier with the work done by H&J roofing. These guys check all the boxes from start to finish. Extremely professional and honest. Did a fantastic job on my roof and cleaned up nicely before they left. Would highly recommend to anyone, 5 star rating!
Barbara Wishart
The roof was replaced 110 percent. After the work was done they cleaned up all items. They also repair decks fences. Will use again when we need repair work done.

Great job on the roof. Went above and beyond cleaning up after each day. Found a potential fire hazard in our vent line did there best to fix the problem. Good price and on time.

Cannot speak highly enough of Henk from H&J!! We reached out with an urgent inquiry as we are looking at buying a home we just found out needs a new roof asap. I received a call back quickly (had not left a vm, he just called based on my missed call) and took the time to walk me through what would be required, materials, time and a ballpark cost. (He offered to come out right away but we haven't yet bought home and I just asked for ballpark) I had various questions and he took the time to answer everything patiently & in depth, very genuine and personable. The ballpark quote I received from H&J was significantly less than the other ballpark quotes we were given by others looking at the exact same thing. If proceeding with this purchase, we will 100% be going with H&J for our roof and other exterior changes we may choose to make. You simply cannot beat genuine honest and straightforward business owners who are in it because they love and care about what they do!! Thank you H&J for the peace of mind!

I hired this company to strip the old siding from my four level split home and detached double garage, and replace it with Hardie board and appropriate trim. They did an absolutely outstanding job. The initial quote was detailed and accurate. They provided a lot of consulting to determine the best color and style for our home. Once the project started, they maintained an extremely clean site and and completed the job on time and on budget. There were a number of finicky challenges for them to work through on my older home to complete the job, which they managed very successfully. I highly recommend H&J.

Common Materials

Materials matter in roofing. Selecting the right materials is an important aspect of construction as it impacts the overall structure, durability, and appearance of a building or home. Different roofing materials offer varying levels of protection against the elements, energy efficiency, and fire resistance – so choosing the right material is essential.


PVC is a popular material for flat roofs for a good reason. Lightweight, durable, & flexible, it’s easy to install, low maintenance and resistant to punctures, cracks, and fire. It’s the perfect eco-friendly material that offers a long-lasting solution!


The versatility and affordability of bitumen are what make it the ideal material for flat roofs. Bitumen is available in various forms, including rolls, shingles, and membranes. With its low cost and long lifespan, bitumen is a great cost-effective and low-maintenance material option.

Flat Roofing Components

A flat roof isn’t like your traditional roof. Flat roofing is characterized by its flat or slightly sloped surface, which differs from traditional pitched roofs’ sloped surfaces. The design and components of a flat roof are carefully selected to ensure a durable and long-lasting roofing system for your home.


Are you worried about water damage? A flat roof’s vapour barrier prevents moisture from infiltrating inside. The waterproofing membrane serves as the final barrier against water and other elements to avoid structural issues and remain protected.


When Calgary’s cold weather strikes, you want good insulation to keep you warm. The insulation in flat roofs improves energy efficiency, which not only reduces utility costs but also boosts indoor air quality. It’s what helps keep you warm while minding your health and wallet.


A firebreak acts as a barrier between the roof and the building structure. It reduces the risk of fire spreading from the roof to the rest of the building and is an essential aspect of fire safety that provides peace of mind to everyone under a flat roof.


The base sheet is a crucial component of flat roofs. Made of reinforced, asphalt-saturated material, it provides added strength and stability and protects against damage from wind, water, and other elements. With a base sheet, it can easily extend the lifespan of your flat roofing system.


The cap sheet provides primary protection against water and the elements. Cap sheets are made of a durable, reinforced material that is resistant to UV rays and temperature changes. In turn, it extends your roof’s lifespan while maintaining aesthetic appeal.

Questions For Our
Roofing Contractors?

A flat roof’s lifespan depends on the materials used, the quality of installation, and the amount of maintenance it receives. On average, a flat roof can last between 15 to 25 years, similar to a traditional sloped roof with asphalt shingles.

It’s recommended you have a flat roof inspected once a year. Annual inspections can help you prevent costly repairs or a full roof replacement by identifying issues as they arise. 

The method for fixing a leak in a flat roof will depend on the cause of the leak and the type of roofing material used. In some cases, a simple repair and patch of the damaged area may be enough. In other situations, the entire roof may need to be replaced. It’s best to consult a professional roofing company for an accurate assessment and repair.
