The Lifespan of Your Roof — and How to Extend It

If you live here in Minnesota, you know our Minnesota winters aren’t just cold – they’re roof-testing, icicle-growing, snow-dumping brutal. Your roof works harder than almost any part of your home, quietly protecting you from snow, sleet, wind, rain, and even the occasional destructive squirrel.

But here’s the good news: with the right care, you can help your roof last years longer — saving yourself from costly repairs or premature replacement. Let’s talk about how long you can expect your roof to last, and some easy, practical steps to give it the best shot at a long, healthy life.

How Long Should a Roof Last?

The lifespan of your roof depends on several factors: the material, the quality of installation, and how well it’s been maintained. Here’s a general guide:

• Asphalt shingles 3-tab: 15-20 years
• Cedar shake/shingles: 25–30 years
• Architectural/dimensional shingles: 15- 25years

Of course, these numbers are for ideal conditions. In Minnesota, “ideal” means we might get two weeks a year where the weather isn’t trying to destroy something. Snow loads, ice dams, hailstorms, high winds, and freeze-thaw cycles can all shorten your roof’s lifespan — especially if small issues go unnoticed.

Why Maintenance Matters

Think of your roof like your car. You wouldn’t drive it for years without oil changes and tire rotations, right? Your roof needs the same kind of preventative care. A little attention now can help you avoid the “my ceiling is dripping” later.

Here are Tonka Roofing’s top tips for keeping your roof in great shape:

1. Get Regular Inspections

We recommend having your roof inspected by a professional at least once a year – ideally in the spring or fall. Inspections can catch small problems like cracked shingles, missing flashing, or early signs of water damage before they turn into big, expensive headaches.

Pro tip: Always get your roof checked after a major storm. Minnesota hail has no mercy.

2. Keep Gutters Clear

Clogged gutters are one of the sneakiest ways to damage a roof. When gutters fill up with leaves, sticks, and pine needles, water can’t drain properly. That water can back up under your shingles or contribute to ice dams in the winter.

Clean your gutters at least twice a year — or better yet, ask us about gutter guards to cut down on the ladder time.

3. Trim Overhanging Branches

We all love trees, but branches hanging over your roof are troublemakers. They scrape against shingles, drop debris, and give squirrels a convenient highway to your attic. Trimming back overhanging limbs protects your roof and reduces the amount of debris landing in your gutters.

4. Prevent Ice Dams

Ice dams are a big deal in Minnesota. They form when heat escapes from your home, melts snow on your roof, and the water refreezes at the edge. This trapped water can seep under your shingles and into your home.

The best prevention? Make sure your attic is well-insulated and ventilated. If you do get ice dams, call Tonka Roofing to safely remove them — don’t attack them with a shovel or hammer.

5. Address Small Repairs Quickly

A missing shingle or loose flashing might seem minor, but water has a way of finding even the tiniest openings. Small repairs done quickly can save thousands of dollars in interior damage later.

6. Keep the Roof Clean

Moss and algae might give your home that “storybook cottage” look, but they’re bad news for shingles. They trap moisture, which can lead to rot and decay. A gentle professional cleaning can remove moss without damaging your roof.

7. Be Mindful of Foot Traffic

Roofs aren’t meant to be walked on regularly. Unless you’re cleaning gutters or retrieving a rogue Frisbee, limit foot traffic to avoid damaging shingles or causing granule loss.

Why Roof Age Matters for Your Home Insurance

Even if your roof looks fine from the ground, insurance companies keep a close eye on its age. Once a roof hits around 10 years old, some insurers see it as a higher liability. That means they may increase your premiums, limit your coverage, or in some cases, refuse to renew your policy until repairs or replacement are made.

Keeping your roof in tip-top shape – with regular maintenance, timely repairs, and quality materials – helps protect not just your home, but also your insurability. And when storm season rolls through, you’ll be in a stronger position if an insurance adjuster does come out for a closer look.

When It’s Time for a New Roof

Even the best-maintained roof will eventually need replacing. Warning signs include:

• Curling, cracked, or missing shingles
• Sagging areas
• Persistent leaks
• Excessive shingle granules in your gutters
• Daylight visible through attic boards

If your roof is approaching the end of its expected lifespan – or showing multiple warning signs – it’s worth having Tonka Roofing come take a look and give you our honest advice.
