Roof Replacement: A Comprehensive Guide for Strata, Residential, and Commercial Properties

2 Aug 2023

The roof is an essential component of any building, providing protection and shelter from the elements. Over time, roofs may deteriorate due to age, weather conditions, or other factors, necessitating a roof replacement. Whether you own a strata property, residential home, or commercial building, understanding the process of roof replacement is crucial to ensure a successful and cost-effective project. In this comprehensive guide, we will explore the key considerations, steps, and best practices for roof replacement in various property types.


A roof replacement refers to the process of completely removing the existing roof of a building and installing a new one in its place. It involves stripping off the old roofing materials, inspecting and addressing any underlying structural issues, and then installing new roofing materials to ensure the integrity, functionality, and longevity of the roof.


Before embarking on a roof replacement project, it is crucial to assess the condition of the existing roof. Look for signs of damage such as leaks, missing or damaged shingles, sagging areas, or excessive wear and tear. Engage a professional roofing contractor, like Mountain West Roofing, to conduct a thorough inspection and provide an assessment of the roof’s condition. This evaluation will help determine whether a roof replacement is necessary or if repairs and maintenance can extend its lifespan.


Once you have established the need for a roof replacement, careful planning and budgeting are essential. Consider the following factors:

  • Material Selection: Choose roofing materials that are durable, weather-resistant, and suited to the specific property type. Options can include asphalt shingles, TPO or PVC roofing, torch-on roofing, or other materials.
  • Building Regulations and Permits: Research local building codes and regulations regarding roof replacements, as permits may be required. Ensure compliance with all necessary legal requirements.
  • Budgeting: Regardless of whether your new roof installation has been in the planning process for a while or is caused by unexpected events, it’s a considerable, but necessary, home investment.

Develop a realistic budget that includes all associated costs, such as materials, labour, permits, and any unforeseen expenses. Allocate funds for potential repairs or upgrades to the underlying roof structure, if necessary.

Before the roof replacement work begins, take the following steps:

  • Notify Residents or Tenants: If you own a strata or residential property, inform residents or tenants about the upcoming roof replacement project. Provide details regarding the timeline, potential disruptions, and any necessary precautions they should take.
  • Protecting Property and Landscaping: Remove any valuable or fragile items from the roof area and protect surrounding landscaping to prevent damage during the construction process.


The roof replacement process typically involves the following steps:

  • Removal of Existing Roof: The old roof is stripped off, including shingles, underlayment, and any damaged sections. Then inspection of the underlying structure takes place, identifying any signs of deterioration or damage.
  • Repairs and Upgrades: Any underlying structural issues, such as damaged decking or compromised supports, are addressed before proceeding with the installation of a new roof.
  • Installation: Installation of a new underlayment is completed, followed by the chosen roofing material, ensuring proper alignment, sealing, and ventilation.
  • Gutters, Flashing, and Skylights: Replacement or repairs of gutters, flashing, and skylights as necessary are completed to ensure proper functionality and water drainage.
  • Cleanup: The work area is then thoroughly cleaned, including the removal of all debris and nails.


After the roof replacement has been completed, we recommend that you establish a regular maintenance routine to maximize the lifespan of your new roof. Conduct periodic inspections, clean gutters, and address any minor repairs promptly. Regularly remove debris and ensure proper drainage to prevent water accumulation. Additionally, consider scheduling roof inspections every few years to identify any potential issues early on.


Strata properties, which typically consist of multiple units or buildings, require a unique approach when having the roof replaced. Here are some key points to consider:

  • Collaboration and Communication: Strata roof replacements involve coordination between property owners, strata management, roofing contractors, and residents. Clear communication channels and consensus building are vital to ensure a smooth roof replacement process.
  • Strata Bylaws and Regulations: Before initiating a roof replacement project, it is crucial to review strata bylaws and regulations. These guidelines may specify roofing materials, design restrictions, noise restrictions, and project timelines.
  • Contractor Selection: Engaging a professional roofing contractor experienced in strata properties is essential. Look for contractors like Mountain West Roofing with a proven track record, and proper licenses, insurance, and warranties to ensure high-quality workmanship and peace of mind.


For homeowners, a roof replacement represents an opportunity to enhance both the aesthetics and functionality of their property. Here’s what to consider:

  • Roofing Material Selection: There is a wide range of roofing materials available, including asphalt shingles, TPO or PVC roofing, torch-on roofing, and more. Consider factors such as durability, energy efficiency, budget, and architectural compatibility when choosing the right material for your residential roof replacement project.
  • Weather Considerations: Assessing the climate and weather conditions in Vancouver are important. Different roofing materials have varying levels of resistance to wind, rain, snow, and sunlight. Selecting a material that can withstand local Vancouver weather patterns will ensure long-lasting protection for your home.
  • Energy Efficiency: Roof replacements provide an excellent opportunity to improve your home’s energy efficiency. Consider different roofing options that can help reduce energy consumption and lower utility bills.


Commercial buildings demand robust roofing solutions to protect assets, occupants, and operations. Here are key factors to keep in mind:

  • Safety and Compliance: Commercial roof replacement projects require adherence to safety regulations and building codes. Ensure the roofing contractor you hire, like Mountain West Roofing, is well-versed in these requirements to avoid legal complications and liability issues.
  • Minimal Disruption: Commercial spaces often have tenants, customers, or employees who need uninterrupted access. Plan the roof replacement process to minimize disruptions, considering working hours, noise control measures, and site safety.
  • Longevity and Maintenance: Select roofing materials with a focus on durability and low maintenance. This will help minimize repair costs, extend the roof’s lifespan, and ensure optimal performance for years to come.


Whether it’s a strata, residential, or commercial property, by following this comprehensive guide, you can navigate the process with confidence, ensuring a successful roof replacement project that provides long-lasting protection for your building. Remember to assess the need for replacement, plan and budget meticulously, hire a reputable roofing contractor, and adequately prepare the property and residents or tenants for the construction phase. With proper maintenance and care, your new roof will continue to safeguard your property for years to come.
