Installations of new roofing systems are sometimes necessary to replace old or damaged roofs. It typically starts with the removal of the old roof and inspection of the roof deck to ensure that it is in good condition. The deck is then repaired or replaced if necessary. Next, an underlayment is installed to provide additional protection against moisture.

The new roofing material is then installed, which can range from asphalt shingles, metal roofing, or tile. Flashing is installed around chimneys, skylights, and other roof penetrations to ensure a watertight seal. Finally, the roof is inspected to ensure that the installation was done correctly and meets building codes and industry standards. It is important to hire a professional roofing contractor for roof installations as it requires expertise and specialised tools to ensure that the roof is installed properly and will last for many years.
