Ensuring comfortable climates in your home or office, providing efficient and reliable heating, ventilation, and air conditioning solutions.
Commercial Roofing
Commercial roofing is a great investment for any business. It can help to protect your building from the elements and maintain its aesthetic.
Metal Roofs
Metal roofs are favoured for their fire-resistant qualities, longevity, and speed of installation.
Asphalt Roofs
Asphalt shingles are proven to effectively shed water off the roof as well as enhancing your home’s beauty.
Roof Repair
When detecting a leaky roof, timing is everything. If caught soon, the roof can possibly be salvaged and repaired.
Ventilation
Proper ventilation is essential to prolonging the lifespan of your roof. No two roofs are the same so we create custom ventilation for each project.
Aluminum Siding, Soffits, Fascia & Eavestrough
Proper installation of fascia & soffits are essential to lengthening the lifespan of your roof. Soffit & fascia are important for proper ventilation.
Skylights
Skylights can be flat or domed, fixed or vented. Some operate by an electric motor, while others operate manually. We carry all styles and sizes.

Dylan and his crew did our Lorne Park property roof, with precision, respect and perfection. Arthur is top tier! If you need anything regarding roofing, these are your people. They treat your property, like it is their own. Thank you, Dilmar!

Trustindex verifies that the original source of the review is Google.We had a roof reshingled by Dilmar roofing. It was a pleasure dealing with Dylan. The crew of Arthur, Doug and Jamal were excellent. We have a steep roof and I was very impressed with the safety measures they took. They tarped the site and did a very good job of cleaning up after. They arrived on time and since they sheathed the roof before shingling, the project was completed over two days. I am very happy with the work.

Trustindex verifies that the original source of the review is Google.Dilmar Roofing has been our family's go-to roofing company for over a decade! From start to finish, they provide excellent service, honest communication, and exceptional attention to detail. Over the years, multiple members of my extended family have used Dilmar Roofing — my parents had their roof done, one of my sisters had her roof replaced, and my other sister trusted them with both of her homes. Every single time, the experience has been great!! Highly recommend!

They dud our roof in Bradford in 2010 and eavestroughs in 2023 on our new house in Sundridge. They did an awesome job and we recommend Dilmar Roofing for any future roofing needs.
