In New Westminster, your roof isn’t just a structure—it’s your first defense against the rain, wind, and west coast moisture. But too often, homeowners wait until leaks or visible damage occur before calling a roofer.

At JMT Roofing, we want to change that mindset. "Preventative roof maintenance" is the single most important thing New Westminster homeowners can do to avoid expensive repairs—or a full replacement. In this post, we’ll break down why regular roof check-ups save you money and how to stay ahead of BC’s unpredictable weather.

New Westminster gets over 1,100 mm of rain annually, and while it doesn’t see much snow, windstorms and fluctuating temperatures can take a serious toll. Moisture leads to moss buildup, which leads to shingle lifting, wood rot, and eventual leaks.

Your roof may look fine from the street, but what’s happening underneath could be costing you.

Common local damage includes:

• Soft spots from long-term moisture
• Blocked gutters leading to ice damming
• Moss growth pulling shingles up
• Flashing corrosion near chimneys and skylights

A single unnoticed leak can damage insulation, drywall, and even electrical wiring. But most of this is preventable. An annual inspection—especially after winter or major storms—can identify:

• Missing or cracked shingles
• Weak flashing or seals
• Blocked drains or downspouts
• Signs of animal or insect intrusion

Cost to fix a small leak? Around \$250–\$500.
Cost to replace an entire roof due to mold damage? $12,000–\$20,000.

We’ve seen New West homeowners avoid massive costs simply by booking a yearly check-in.

Langley might get the headlines for tree cover, but New Westminster has plenty of leafy streets and shaded roofs too. That means one thing: moss.

Left unchecked, moss holds water on your shingles, making them rot faster. Add clogged gutters to the mix, and you’ve created a roof system that fails from the outside *and* inside.

Here’s how to prevent that:

• Clean gutters twice per year
• Install gutter guards if surrounded by trees
• Use moss treatment every 1–2 years (eco-friendly options available)
• Trim back overhanging branches
