Preparing your roof for Canadian winters is essential—especially in Newmarket and across the York Region, where heavy snow, freezing rain, and ice buildup can take a serious toll on residential roofing systems. At Guaranteed Roofing, we’re committed to helping homeowners protect their properties with reliable, preventative roofing solutions.

This case study highlights how one Newmarket family used our Pre-Winter Roofing Checklist to safeguard their home from common winter roofing issues and extend the life of their roof.

The Homeowner: Getting Winter-Ready in Newmarket, Ontario

In late October, a homeowner in Newmarket contacted Guaranteed Roofing after experiencing ice dams and minor leaks the previous winter. With another harsh season approaching, they wanted professional help ensuring their roof was fully prepared. After reviewing our York Region Pre-Winter Roofing Checklist, they scheduled a complete seasonal inspection and maintenance visit. They weren’t just looking for repairs—they wanted long-term roof protection and improved winter performance.

Step 1: Eavestrough & Gutter Cleaning for Winter Roof Protection

One of the most important roofing maintenance tasks in Newmarket is eavestrough or gutter cleaning. Blocked gutters trap melting snow, causing water to freeze and create destructive ice dams.

During our inspection, our roofing team found:

A heavy buildup of late-fall leaves
Standing water in several gutter sections
Downspouts partially clogged with debris

We completed a full gutter cleaning and flushed the drainage system to ensure proper flow—crucial for preventing winter roof leaks and ice-related damage. Clean gutters are a key part of any York Region winter roofing maintenance plan.

Step 2: Roof Shingle & Flashing Inspection in Newmarket

Loose shingles, worn flashing, and exposed seams are some of the most common winter roofing issues in Newmarket and York Region.

On this home, we identified:

Lifted asphalt shingles
Minor deterioration around chimney flashing
Early signs of sealant wear near the roofline

We repaired and replaced affected shingles and reinforced the flashing to prevent water intrusion during freeze-thaw cycles. These small roofing repairs significantly reduce the risk of winter roof leaks.

Step 3: Attic Insulation & Ventilation Assessment

Proper attic ventilation is essential for any home in the York Region. Without it, warm indoor air rises and melts the snow on the roof, which then refreezes along the eaves—forming ice dams.

Inside the attic, we found:

Uneven insulation coverage
One ventilation channel partially blocked

Our team passed on the information to the homeowner, restored airflow, and ensured the attic ventilation system met winter performance standards. This improves energy efficiency and prevents ice dam formation—a major roofing concern in Newmarket and York Region.

Step 4: Roof Perimeter, Ice Barriers & Winter Readiness

Finally, we examined the roof’s perimeter, ice guards, and protective barriers. While the home had a solid roofing structure, our team reinforced several vulnerable areas for improved winter safety.

The Results: A Fully Winter-Protected Newmarket Roof

By following Guaranteed Roofing’s Pre-Winter Roofing Checklist, this Newmarket homeowner gained:

A roof fully prepared for harsh winter weather
Improved drainage and reduced risk of ice dams
Increased energy efficiency through proper attic ventilation
Extended roof lifespan thanks to early detection of issues
Peace of mind knowing their home is protected before the first snowfall

This project shows how preventative roofing maintenance can save homeowners throughout Newmarket and York Region thousands in future repairs.
