January 21th, 2023

Preparing a roof for installation is a crucial step in the roofing process. It ensures that the new roof is installed correctly and safely, and that the underlying deck is in good condition to support the new roof. Roofing companies typically follow a whole process to prepare a roof before installation.


The first step in the preparation process is to remove the old roof; this involves removing the old roof top, felt, beams, and other materials that make up the old roof. This step is usually done by a team of experienced roofers using specialized equipment such as roofing hammers, pry bars, and dumpsters for debris removal.

Once the old roof has been removed, the next step is to inspect the underlying deck. This step is crucial as it allows the roofing company to identify any issues or damage that may need to be repaired before installing a new roof. The inspection typically includes looking for signs of moisture, rot, or structural damage.

If any issues or damage are found during the inspection, the roofing company will make the necessary repairs before proceeding with the installation. This may include replacing any damaged decking or reinforcing any weak areas.

After the repairs are made, the next step is to install the underlayment. This is a layer of material that is installed on top of the deck to provide a barrier between the deck and the new roof. It helps to protect the deck from moisture and other types of damage.

The next step is to install insulation. These are installed to prevent condensation from building up inside the structure. This step is particularly important in areas with high humidity or temperature fluctuations.

The roofing company will then install new gutters and drains to ensure that rainwater can flow freely and prevent damage to the roof. This step is also important in ensuring that the roofing system is properly ventilated.

    Following steps

    Finally, the new roof is installed. This step will vary depending on the type of roofing system that is being used. For example, if it’s TPO roofing system, the team of experienced roofers will install the TPO sheets, using specialized equipment such as RhinoBond Attachment Method and rollers. If it’s PVC roofing system, the team will install PVC sheets, using specific adhesives, and in some cases, mechanical fasteners.

    It is important to note that preparation for each roofing project may vary depending on the specific needs of the building and the condition of the existing roof. However, the steps outlined above are typically followed by most roofing companies in the United States.

    Crew and equipments

    In terms of the professionals and equipment necessary for the preparation process, it usually requires a team of experienced roofers, a roofing contractor, and specialized equipment such as roofing hammers, pry bars, RhinoBond machines, rollers, dumpsters, ladders, and scaffolding.

    In summary, preparing a roof for installation is an important step in the roofing process. It involves removing the old roof, inspecting the underlying deck, making any necessary repairs, installing underlayment, insulation, new gutters and drains, before installing the new roof. Roofing companies in the US typically follow this process to ensure the safety and longevity of the new roof. The process requires a team of experienced roofers, a roofing contractor, and specialized equipment. It is important to consult with a qualified professional to determine the specific preparation process for your building’s roof.
