When it comes to protecting your inventory, business assets, and employees, a quality commercial roof is essential. Unfortunately, no commercial roof lasts forever, and a commercial roof replacement might be necessary if yours is showing signs of deterioration. A professional replacement process involves several important steps to consider. In this article, we provide a professional step-by-step guide to walk you through the entire commercial roof replacement process.
Step 1 - Initial Roof Inspection & Assessment
Your roof replacement journey begins with a thorough inspection of your existing roof. A professional roofer will conduct a comprehensive inspection to assess the extent of any damage, as well as to consider the structural integrity of your roof deck.
Things roofers will look for include:
• Persistent leaks
• Cracks and worn surfaces in your roof covering
• Blisters or punctures
• Granule loss
• Water ponding
The decision to repair or replace your roof will be dependent on the extent of the damage. If there are major repairs required, it’s often more prudent to go ahead with a roof replacement, which will save you in the long run. Keep in mind that commercial roofs that are anywhere between 15 and 30 years old may be approaching the end of their life.
Step 2 - Choosing The Right Roofing System
Once you’ve given the go-ahead for a replacement roof, it’s time to select the best-suited commercial roofing system for your building. Each system comes with its own cost considerations, longevity, and energy-efficiency rating. Here are the most common commercial roofing systems to choose from.
• TPO (Thermoplastic Polyolefin): This single-ply membrane is a popular choice and is known for its cost-effectiveness and durability.
• EPDM (Ethylene Propylene Diene Monomer): A synthetic rubber membrane that offers superior weather resistance and good durability. A
• Modified Bitumen: This asphalt-based system is reinforced with polymers to allow for flexibility.
• Built-Up Roof (BUR): A multi-layered system using layers of asphalt and felt, topped with a cap sheet.
It’s best to discuss these commercial roof replacement options with a trusted roofing professional to come to the best roofing solution for your business’ needs.
Step 3 - Getting A Detailed Estimate & Timeline
Detailed estimates help you know exactly what you’re in for financially. An estimate should be itemized to include material costs, labor costs, possible disposal costs, as well as any additional services required. Make sure you understand the payment arrangement ahead of time as well. An estimated project timeline will help you to plan around several contingencies, such as bad weather, delivery delays, or business activities that require priority. Your commercial roof replacement timeline should also be something that is discussed and decided upon with your roofer.
Step 4 - Permits, Insurance, & Code Compliance
Any building permits required should be arranged by your roofing contractor and should adhere to local building codes and compliance regulations. It’s a good idea to check the associations and memberships that your desired contractor holds with building authorities in Florida. You’ll also be able to get a good idea about their knowledge of building codes during your initial consultation. Remember that it’s vitally important to ensure your contractor has comprehensive construction liability insurance to cover any possible onsite liabilities. Although accidents are rare, it’s a must to have the cover.
Step 5 - Preparing The Site & Building
Once building day arrives, your contractor will begin to prepare your commercial site for the roof replacement. It’s important to establish a clear line of communication and safety protocol with your employees on site. The work area should always be cordoned off with appropriate signage. Be sure to prepare for any dust removal, as roofing work can lead to settling dust, particularly during the demolition period.
Step 6 - Tear-Off & Disposal Of Old Roofing
After securing the construction area, it’s time to remove your old roofing. During this process, your old and existing roof covering will be torn off the roof deck by the use of powerful roof cutters. All roofing debris should be immediately placed into the provided dumpsters to prevent any mess. Once the old roof covering is completely removed, the team will conduct a thorough roof deck inspection to ensure any signs of rot or water damage aren’t present. In some instances, the roof deck may require attention before the new roof covering is installed.
Step 7 - Installation Of The New Roofing System
It’s finally time for your new roof to be installed. When specified, insulation will first be installed onto your roof deck ahead of the panel or membrane installation. Your desired roof covering will consist of the appropriate installation techniques, which are then followed by flashing installation to ensure watertight seals. Any drainage concerns should be addressed before hand , including gutters and downpipes.
Step 8 - Final Inspection & Walkthrough
A final roofing inspection and walk-through is vital to ensure your roof replacement meets all the required standards. Once your roofing professional has conducted a full inspection, including a leak test, you will also be given the option to do a walk-through with your contractor. Finally, the contractor will conduct a final site cleanup to remove any remaining debris or roofing materials.
Step 9 - Warranty, Maintenance Plan & Documentation
If your roofing professional hasn’t already provided you with the roof warranty documents, it’s recommended to ask for these. These will give you a breakdown of the manufacturer’s warranty as well as a workmanship warranty that’s provided through your roofing contractor. Be sure to read through the warranty carefully to prevent any unfortunate surprises at a later stage. Another important consideration is to decide on a preventative roofing maintenance plan with your roofer. This should involve regular roofing inspections and roof cleaning to help ensure your roof’s longevity.
