The critical reviews
The one and two-star reviews, first. These are what a star average hides, and they are the reason this page exists.
We hold no one or two-star review text for Efficient Roofing. That is not the same as there being none — it means our capture did not reach any. The rating breakdown above is Google’s own count and is the number to go on.
Other reviews we hold
7 more of the 7 reviews we hold text for, most recent first. We do not hold every review Google has.

Brian and his crew did an amazing job installing a new Duradek skin on our patio deck. Really great guy, can’t recommend him enough!

Our family has been working with the Theriault family at Efficient Roofing for almost 50 years; I have known Brian since we were young and we are both honoured to take over our fathers’ visions of being trusted construction companies in Durham region. Honesty and Integrity have been the building blocks of both our companies. We continue to hire Brian and his team to complete our flat, standard, and steep pitched roofs for new builds and renovations

Brian came recommended to me and he recently repaired a missing shingle, plus nailed down others for free...he didn't even do the original job! Much appreciated, Brian!

Brian and his team were extremely professional and amazing to deal with. They were able to come by, inspect our roof, provide recommendations and complete the job while keeping us informed throughout the entire process. I would highly recommend him and his team to anyone in the Durham region seeking a professional and high quality roof repair/installation
What Efficient Roofing says about itself
Taken from the business’s own website. We have not checked any of it. These are quotes, not credentials — a roofer writing “licensed and insured” on their homepage is not evidence that they are.
States a founding year
“…Since 1974 Duradek has provided customers long…”
Family owned
“…Being a second generation, family owned company we take pride in the vision…”
Their site also states: states years in business.

Where this page comes from
Every figure above is Google’s, captured on 24 September 2026. The star average and the 8 ratings behind it are counted by Google across all of its reviews. The review text on this page is a sample — we hold 8, of which 7 have any text — and it is not everything Google shows.
Roof Warden does not verify licenses, bonds, insurance or workers’ compensation cover, and nothing on this page should be read as though we had. Confirm those directly with the contractor and with your state or provincial licensing body before you hire anyone.
There is not much data on Efficient Roofing. A short record here means our capture found little — not that there is nothing to find, and not that the business is new or inactive.
