If your Calgary home needs both a roof and siding replacement, one key question often comes up — which should you do first?
At first glance, it might seem like it doesn’t matter, but the truth is, the order of your renovation can affect your home’s protection, energy efficiency, and even total project cost.
In this 2026 homeowner’s guide, we’ll break down what to consider when planning exterior renovations in Calgary’s unique climate, and help you make the smartest long-term decision.
Roof or Siding First? The Short Answer
In most cases, you should replace your roof before your siding.
Here’s why:
-
Roofing work can cause debris, tools, and materials to fall along your walls and siding.
-
Replacing the roof first ensures your home is watertight before redoing the siding.
-
Roof flashing and drip edges often overlap the siding line — meaning the roof should be installed first for proper sealing.
Doing the siding after the roof helps ensure all joints and flashing are secure and weatherproof.
That said, there are exceptions depending on your home’s structure, age, and condition — which we’ll explain below.
When to Replace Your Roof First
If your roof is old, damaged, or showing signs of leakage, always start with the roof.
1. Prevent Water Damage
Calgary weather can be unpredictable — with sudden snowfalls, heavy rain, and hailstorms. If your roof is compromised, water can easily seep behind the siding, causing rot or mold.
Replacing your roof first creates a solid barrier that protects your new siding from damage during future storms.
2. Protect Your New Siding
Roofing projects can be messy. Shingles, nails, and falling debris can easily scratch or dent new siding. By completing the roof first, you prevent potential damage to freshly installed panels or trim.
3. Proper Flashing and Finishing
Roofing systems typically overlap the upper edge of the siding at eaves and around gables. Installing the roof first allows contractors to integrate flashing, drip edges, and soffits correctly — ensuring watertight protection.
✅ Pro Tip: Schedule your roof replacement early in the season — spring or early summer — so siding work can follow right after, avoiding cold-weather installation challenges.
When It Makes Sense to Replace the Siding First
Although rare, there are certain cases where siding should be replaced first:
1. Structural or Moisture Issues
If the siding is severely damaged — rotting, warping, or letting water in — it could compromise your home’s insulation and structure.
In such cases, replacing the siding first can help prevent further interior moisture damage before tackling the roof.
2. Aesthetic or Energy Upgrades
If your roof is still in decent condition but your siding is outdated or inefficient, consider upgrading the siding first. Modern insulated siding in 2026 offers energy-saving properties and can reduce heat loss during Calgary’s cold winters.
Still, even in these cases, it’s best to have a professional inspection before deciding on the order.

How Calgary’s Climate Affects Your Renovation Plan
Calgary’s climate is unique — it’s dry, windy, and prone to sudden weather shifts. This can impact both the order and timing of your renovations.
-
Snow and hail can expose weaknesses in roofing or siding.
-
Temperature swings cause materials to expand and contract — so proper installation sequencing is critical.
-
Spring and early fall are the best times for roofing and siding projects to ensure optimal adhesion and sealing.
Because your roof and siding work together to protect against Alberta’s elements, coordinating both projects within one season is ideal.
Coordinating Roof and Siding Replacements Efficiently
Replacing both your roof and siding in the same renovation cycle has huge benefits — especially when managed by a single contractor like Construct Vision.
Here’s why:
-
One crew can synchronize installation, ensuring all transitions (flashing, trim, eaves) align perfectly.
-
Bundled projects often save money — shared setup, waste removal, and permits.
-
The entire exterior gets a fresh, cohesive look.
A unified project approach guarantees consistent materials, colours, and finishes, improving your home’s curb appeal and long-term performance.
How to Know When It’s Time to Replace Your Roof or Siding
Roof Replacement Signs
-
Curling or missing shingles

If your home shows any of these signs, it’s time to plan a 2026 renovation schedule that tackles both projects efficiently.
Best Practice: Roof and Siding Done Together
Many Calgary homeowners in 2026 choose to replace the roof and siding together. It’s the most cost-effective and convenient approach because:
