Your roof is your home’s first line of defence against snow, wind, hail, rain, and temperature extremes. But like anything under harsh conditions, it ages, wears, and eventually begins to fail. The good news? Many issues can be caught early with a regular inspection—before they lead to a full roof repair or even a roof replacement.
In this post, we’ll walk you through a practical annual roof inspection checklist. Follow this guide, and you’ll be better prepared to detect trouble before it becomes a costly headache.
Why Annual Roof Inspections Are Essential in Calgary
Before we jump into the checklist, here’s why it matters:
- Catch Small Issues Early: A few loose shingles or a failing flash might cost a few hundred dollars to fix. Let that develop into leaks, structural rot, or insulation damage, and you’re talking thousands.
- Prolong Roof Life: Routine inspections and minor interventions slow the decline, extending the life of your roof and delaying the need for a roof replacement.
- Protect Your Home’s Interior: Water infiltration caused by a leaky roof can cause damage to ceilings, walls, insulation, and your home’s overall structure.
- Prepares You for a Roof Replacement: Annual roof inspections in Calgary give you clues as to how much life is left in your roof.
- Insurance and Resale Value: A documented inspection history looks good for claims and makes your home more appealing to potential buyers.
Annual Roof Inspection Checklist
Let’s get into your annual roof inspection checklist to get you started. Just remember, safety first! Always use a sturdy ladder and non-slip shoes, and don’t walk on a steep roof unless you have experience. If in doubt, call in the pros.
Step 1: Start from the Ground – Exterior Overview
Before setting foot on your roof, walk the perimeter. Use binoculars if necessary.
- Look for missing, cracked, curling, or blistered shingles. These are signs that a shingle has lost integrity.
- Check your gutters and downspouts. Observe any granule loss (sand-like granules), ensure they’re securely attached, and that water flows away from the foundation.
- Inspect soffits, fascia, and eaves for rot, cracks, peeling paint, or evidence of animal or insect damage.
- Note any sagging roof lines or dips. This could suggest structural issues or weakened decking, which should be addressed immediately.
- Examine chimneys, skylights, vents, and other penetrations for cracked or rusted flashing or compromised seals.
- Check for moss, lichen, or mould growth on shingles — these hold moisture and deteriorate the roof.
Step 2: Climb Up & Walk the Roof (If Safe to Do So)
If you’re comfortable and safe doing so, a closer inspection can reveal more subtle issues:
- Look for loose or popped nails that may have lifted shingles.
- Examine the flashing in valleys, at transitions, around chimneys, pipes, and dormers. Ensure it’s properly sealed, not rusted, warped, or separated.
- Check pipe boots, skylight seals, and other caulked areas for cracks or aging.
- Inspect ridges, hips, and valleys for broken or cracked shingles.
- Verify proper overhangs and shingle alignment—shingles should extend slightly over eaves and into gutters (but not excessively).
- Look for ponding water or areas where water might collect (on low-sloped roofs).
- Check that venting, ridge vents, and soffit vents are unobstructed.
Step 3: Inspect From Inside (Attic / Ceiling)
Some damage isn’t obvious from the exterior but will show on the inside.
- Check for water stains, discoloration, or mould on the underside of roof decking, rafters, or ceiling drywall.
- Look for light shining through small holes or gaps in the roof deck.
- Inspect insulation for signs of moisture, compression, or displacement.
- Ensure attic ventilation is functioning. Poor ventilation leads to moisture accumulation, which can warp decking or encourage rot.
- Check for condensation or dampness, especially in colder months.
- Look at rafters and structural supports for sagging or cracking.
Step 4: Record & Prioritize
- Document photos and take detailed notes of any issue you find.
- Prioritize urgent roof repairs, such as active leaks, flashing failures, or sagging portions, over maintenance tasks like gutter cleaning and securing loose shingles.
- Keep track of your food inspections each year so you can compare what’s new or worsening year over year.
- Use this inspection history when consulting a contractor or negotiating a roof repair or roof replacement.
When to Call for Roof Repair or Roof Replacement
While some issues may be minor and easy enough to handle on your own, it’s important to know when to call in the professionals:
- Roof Repair: Great for isolated damage such as a few missing shingles, worn or rusted flashing, or localized leaks. If the structure and most of the roof are still sound, a roof repair is often the most cost-effective option.
- Roof Replacement: If you find extensive damage, widespread wear, sagging, multiple leaks, or your roof is past its expected service life, it may be more economical in the long run to consider a roof replacement rather than continuing repairs.
In Calgary’s extreme climate, your roof can take a beating. Detecting issues early via an annual roof inspection can help you prevent major damage and save you money.
Tips for Maximizing Your Roof Inspection in Calgary
- Schedule in spring or early fall when the roof is clear of snow or ice, and before major seasonal storms.
- Inspect after major weather events (hailstorms, high winds)—damage may not show immediately, but can worsen quickly.
- Get a professional roof inspection for complex roofs (steep pitches, multiple levels, difficult access).
- Maintain gutters and trim overhanging trees to prevent debris and branches from falling and causing additional damage to your roof.
- Keep good records—logs, photos, and contractor reports—as they help with warranty claims or resale.
