Your roof is one of the most critical components of your home—but also one of the most vulnerable. Exposure to weather, aging materials, and poor maintenance can lead to a range of problems that affect your home’s safety, structure, and energy efficiency.
In this blog, we’ll highlight some of the most common roofing services calgary issues homeowners face and provide practical tips on how to prevent them.
1. Leaks and Moisture Damage
The Problem:
Leaks are the most common—and often the most damaging—roofing issue. They can be caused by missing shingles, poor flashing, or clogged gutters. Over time, water intrusion leads to mold, rotting wood, and structural damage.
Prevention Tips:
Inspect your roof after storms
Keep gutters clean to ensure proper water flow
Seal and inspect flashing around chimneys, vents, and skylights
Replace damaged or missing shingles promptly
2. Poor Ventilation
The Problem:
A poorly ventilated roof traps heat and moisture in your attic, which can damage insulation, encourage mold growth, and shorten the lifespan of your roof.
Prevention Tips:
Ensure your attic has intake and exhaust vents
Install ridge or soffit vents for better airflow
Use attic fans if necessary to improve air circulation
Check for condensation during cold months
3. Ponding Water
The Problem:
Flat and low-slope roofs are especially prone to ponding—standing water that doesn’t drain properly. Over time, ponding can degrade roofing materials and lead to leaks.
Prevention Tips:
Ensure your roof has adequate drainage
Regularly clear debris from roof surfaces and drains
Check for low spots or sagging areas and have them leveled
Use tapered insulation on flat roofs to improve slope
4. Damaged or Aging Shingles
The Problem:
Shingles are your roof’s first line of defense. As they age, they become brittle, crack, curl, or fall off entirely, leaving your roof exposed to the elements.
Prevention Tips:
Schedule annual inspections to assess shingle condition
Replace shingles showing signs of wear
Choose high-quality materials with good warranties
Apply UV-protective coatings if recommended
5. Ice Dams (in Cold Climates)
The Problem:
Ice dams form when heat escapes from the attic, melting snow on the roof. The water refreezes at the eaves, causing a backup that can leak into the home.
Prevention Tips:
Insulate and ventilate your attic properly
Use ice and water shields under shingles
Clear snow off your roof after heavy storms
Consider heat cables for trouble spots
6. Clogged Gutters
The Problem:
When gutters are full of leaves and debris, water backs up and can seep under shingles or pool around the foundation. This can damage both your roof and your home’s structure.
Prevention Tips:
Clean gutters at least twice a year
Install gutter guards to reduce buildup
Ensure downspouts direct water away from the home
Check for leaks or gaps in the gutter system
7. Improper Installation
The Problem:
Even the best roofing materials can fail if not installed correctly. Poor workmanship can lead to leaks, premature aging, and voided warranties.
Prevention Tips:
Always hire a licensed and insured roofing contractor
Ask for references and check past work
Make sure the crew follows local codes and manufacturer guidelines
Request a workmanship warranty in addition to the materials warranty
Final Thoughts
Most major roofing problems don’t happen overnight—they start small and get worse with time. With regular inspections, prompt maintenance, and the help of a qualified roofing professional, you can avoid costly repairs and extend the life of your roof.
Being proactive is the key. Don’t wait until there’s water in your living room—know the signs, stay ahead of the damage, and keep your roof in top shape for years to come.
