Why Roofing Matters for Homes & Businesses

For Homes

At home, the roof will safeguard you on the seasonal extremes of Calgary, snow, ice, freeze-thaw, hail, blazing sun and wind. A reliable roof ensures:

• the interior stays dry and warm in winter and cool in summer,

• there is no water coming in the structure through leaks or bad flashing,

• There is no energy lost to heat or air leakage and

• the house has curbside appeal and value.

For Businesses

Business roofs have some extra requirements: extensive surface area, low-profile or flat roofs, significant equipment on top (HVAC units, ventilation systems), increased vulnerability to standing water and even more devastating in case of failure. To a business, failure in the roof can imply its down-time, liability, loss of inventory or equipment, business interruption. Therefore commercial roofing is more demanding in terms of checking, special materials and maintenance.

• Material Choice: This is the most significant variable, with asphalt shingles being the most common and affordable option.

• Removal of Old Roof: The cost includes tearing off and disposing of the existing layers.

• Complexity: The number of valleys, chimneys, skylights, and the height of your home can affect the price.

Material Choices & Local Climate Considerations

It is significant to select an appropriate material to improve performance and life cycle. The climate in Calgary is heavy in snow loads, freezing and thaw, hail prone, and high in UV that will cause materials to break, so contractors suggest a material that can resist these stresses.

• Metal roofing: It is very tough, clears off snow and in summer it tends to reflect a lot of heat; it has long life and maintenance is usually lesser.

• Architectural asphalt shingles: A typical residential, which possesses more wind/hail resistance than simple shingles, is a good value.

• Single-ply membranes (for flat ): This is the perfect fit in commercial low-slope roofs; that is, it has to be installed correctly to prevent leakage, ponding, or separation of the seams.

• Built-up roofing or modified-bitumen (BUR): Governments still use commercial systems that were older; they need to be inspected and maintained frequently.

• Reflective or “cool” finishes: Reflective materials are especially useful on flat, commercial roofs where they reduce the amount of heat gathered and result in a lower heat and energy bill.

Roofing companies in Calgary understand to include snow loads, attic ventilation (to prevent ice dams), eavestrough dimensions, and wind/hail ratings of materials. They also seek to ensure warranties are maintained by having manufacturer specifications (flashings, fasteners) met.

The Process: What Property owners should expect

1. Preliminary Consultation and Evaluation

A contractor comes to the home, examines the condition of the roof, inspects it to either detect any leaks or damages, inspects the drainage, eavestroughs (homes) or rooftop equipment (businesses). They provide alternatives: reparation or replacement, material, cost and time.

2. Written Quote & Scope of Work

A homeowner or business is given a comprehensive quote in terms of materials, labour, old material removal, disposal, permit fees (where applicable), schedule, commencement and completion date, warranty.

3. Preparation & Safety Measures

In any roofing work, the crews install fall protection, scaffold (residential) or rooftop safety systems (commercial), guard landscaping or rented areas, demolition of old materials, and repair any deck or substrate.

4. Installation or Repair Work

Residential: remove old shingles or panels, repair deck if needed, install underlayment, vents, flashing, then install finish material.
Commercial: remove or prepare membrane, install new membrane or apply coating, ensure proper slope for drainage, repair drains and flashings, integrate rooftop units, document work.

5. Clean-Up & Final Inspection

The premises should be tidy-up- nails or scrapings, gutters, inside, are to be inspected, and any areas where there might be a leakage or a breakage. Contractor takes You through the work, shows photos, issues warranty/warranty paperwork.

6. Ongoing Maintenance

Maintenance is also important even after installation. Homeowners are supposed to check the gutters and vents at least once every season; business owners are to follow the maintenance program, which means the inspection should be conducted at least twice a year and after significant weather changes.

Maintenance Tips & Best Practices

• For homes, inspect your roof after major storms (hail, wind) and clear gutters in spring.

• For businesses, schedule inspections at least twice a year—spring and fall—and after any extreme weather or rooftop work. 

• Never ignore any small leaks or pooled water—minor issues escalate quickly in roof systems.

• Choose a contractor who uses photo documentation, provides written reports, keeps detailed maintenance logs—that professionalism signals trust. 

• Make sure that materials are local climate appropriate and that they conform to the conditions of the manufacturer--Bad fasteners or flashing usually nullify warranty or lower lifespan. betterdecoratingbible.com

• When you observe the presence of moss, algae or vegetation on flat roofs, be sure to remove them as soon as possible to prevent the destruction of membrane or the problem of ponding.

• In the case of flat commercial roofs, there should be no unnecessary foot traffic and the rooftop equipment should be well spaced to avoid weight concentration as well as the drains to avoid congestion.
