The process of a commercial roof replacement is a complex and involved one, but we’’ll break it down into the key steps for you:
Roof Inspection
The first step is to inspect the existing roof and assess its condition. This includes evaluating the roof structure, drainage system, and any potential hazards.
- A thorough examination of the existing roof is conducted to assess its current condition.
- The inspector will evaluate the roof structure, deck, drainage system, and any potential hazards.
- The inspector may also take measurements of the roof and make recommendations for the replacement process.
- A core sample in most cases should be taken to assess layers of roofing & insulation. This reveals moisture presence, and will affect the diagnostic approach in what system you go back with. The insulation might be too thin or latent with moisture or bone dry and allows you to go back with a mere cover board under the single ply system. (If someone doesn’t take a core sample, or get clarity on layers existing, run.)
Planning and Design
Based on the results of the inspection, a plan is developed for the roof replacement. This includes the selection of materials and systems to be used, as well as the design of the new roof and any necessary upgrades to the drainage system.
- The design will take into account any local building codes and regulations, as well as the specific needs and requirements of the building. This is important as some areas require limited amounts of layers and or insulation requirements. This will determine a layover vs a tear off.
- The contractor will provide an estimate of the cost of the replacement, taking into account the scope of work, materials to be used, and any necessary permits or fees.
Preparation
Before the new roof can be installed, the old roof must be removed and the deck must be prepared. This often involves repairing or replacing any damaged sections of the deck and installing any necessary insulation.
- The deck must then be prepared, which may involve repairing or replacing any damaged sections of the deck.
- Insulation may also be installed at this stage, depending on the requirements of the new roofing system.
Installation
Once the deck is prepared, the new roofing system can be installed. This typically involves laying down a layer of waterproofing material, followed by the installation of the roofing membrane, flashings, and any additional layers or components as required.
- This typically involves laying down a layer of waterproofing material, followed by the installation of the roofing membrane, flashings, and any additional layers or components as required.
- The contractor will ensure proper installation of all components, taking into account the design and specifications of the new roofing system.
Finishing
The final step is to complete any necessary finishing work, such as installing roof hatches or vents and restoring any landscaping that was disturbed during the roof replacement process.
- The final step is to complete any necessary finishing work.
- This may include installing roof hatches or vents, restoring any landscaping that was disturbed during the roof replacement process, and cleaning up the site.
- The contractor will conduct a final inspection to ensure the new roof has been installed properly and to the specifications of the design.
Warranty and Maintenance
After the roof replacement is complete, it’s important to properly maintain the roof to ensure it lasts as long as possible. This typically involves regular inspections, cleaning, and repairs as needed, as well as taking advantage of any available warranty coverage.
- Proper maintenance will also help to identify any potential issues with the roof early on, so that they can be addressed before they become major problems.
These are the key steps in a commercial roof replacement, but the exact process can vary depending on the type of roofing system being installed, the size and complexity of the roof, and any unique requirements or challenges of the building.
By following these steps, a commercial roof replacement can be completed efficiently and effectively, resulting in a durable and long-lasting roof for the building.
