After the rain, it's important to allow your roof to dry for at least one day before continuing work. If you're replacing or installing a new roof, it's wise to have a tarp on hand to cover vulnerable sections in case of rain. It's not ideal to work on a roof in the rain, as it can be dangerous and cause damage to the wood underneath. If it starts raining during the installation process, it's best to stop the work and cover the roof with a tarp.
This will help prevent water from infiltrating the exposed roof and damaging the coating underneath. Roofers are experienced in working in all conditions, so it's best to let them decide when it's safe to continue. If you're removing an old roof covering and the wooden deck is exposed, you should try to finish this part of the work as soon as possible and cover the deck with an undercoat. It's also important to make sure your roofer is licensed and insured in case of inclement weather. When it comes to roof installation, it's always best to be prepared for rain.
Have tarps and other emergency equipment on hand so that you can quickly cover the roof if needed. It may be worth delaying the start of work if heavy rain is expected. This will help protect your home and interiors from water damage and ensure that your roofer can work safely.
