At AJT Roofing, we specialize in architectural shingles—also known as laminate shingles or dimensional shingles. These are high-performance shingles designed for aesthetic appeal and outstanding weather resistance. Unlike traditional 3-tab shingles, architectural roof shingles feature a multi-dimensional design and are built to withstand strong winds, UV exposure, and heavy snow accumulation—ideal for Ontario’s diverse climate.
We only use products from trusted manufacturers like Malarkey Roofing and CertainTeed, both of which offer some of the industry’s best warranties. Our certified installation ensures that every roof is done to exact specifications for long-lasting protection.
Shingle roofing services include:

Flat roofs are a popular option for garages, additions, porches, and commercial buildings across St. Catharines. However, flat roofs require experienced professionals to prevent water pooling, leaks, and structural issues. At AJT Roofing, we’re highly skilled in all aspects of flat roof installation, flat roof repair, and flat roof replacement.
Our flat roofers use proven, weather-resistant materials such as modified bitumen and torch-on membrane systems that perform in all seasons. We custom tailor every flat roof system to ensure proper slope, drainage, and sealing—protecting your property for years to come.

Your attic ventilation system is one of the most important components of your home’s roofing structure. Without proper airflow, moisture can accumulate in your attic, leading to mold growth, premature shingle failure, and higher energy bills. That’s why AJT Roofing offers high-performance roof vent and solar attic fan solutions to improve ventilation without increasing your energy costs.
Solar ventilation uses the power of the sun to operate fans that pull hot air and moisture out of your attic. This reduces the workload on your air conditioner, extends the life of your shingles, and lowers the risk of winter condensation and ice damming.
Our roof ventilation services include:
Benefits of solar-powered roof ventilation:
✅ Operates without electrical wiring
✅ Reduces attic heat buildup
✅ Prevents mold and rot
✅ Boosts energy efficiency in all seasons
