How to Prepare My Roofing Before Installing Metal Roofing Over Plywood?
If you've decided to upgrade your roofing to a durable and long-lasting metal roof over plywood, proper preparation is key to ensuring a successful installation and maximizing the benefits of your new roofing system. Here are essential steps to prepare your roofing before installing metal roofing over plywood:

1. Inspect and Repair
Before beginning any roofing project, inspect your current roof for any signs of damage, leaks, or structural issues. Address any existing problems and make necessary repairs to ensure a stable foundation for the metal roofing. Replace any damaged or rotted plywood and secure loose shingles or roofing materials.

2. Clean the Roof Surface
A clean surface is crucial for the metal roofing to adhere correctly. Remove debris, dirt, moss, and algae from the existing roof surface. Power washing or using a mild cleaning solution can effectively clean the roof, but be cautious not to damage the existing roofing materials during the cleaning process.

3. Add Underlayment
Once the roof deck is in good condition, install an appropriate underlayment. Roofing underlayment provides an additional layer of protection against water infiltration and acts as a moisture barrier. It helps to prolong the lifespan of your metal roofing and enhances its overall performance.

4. Consider Insulation
If you desire improved energy efficiency, consider adding insulation during the preparation phase. Insulating your roof can lower heating and cooling expenses and assist in the control of internal temperatures. To choose the finest sort of insulation for your unique needs, it is best to speak with a roofing expert.

5. Check Building Codes and Permits
Always check local building codes and obtain necessary permits before starting any roofing project. Compliance with regulations ensures that your metal roofing installation meets safety and structural standards.
