For better performance and efficiency -

• Optimal system integration: An under-deck system is essentially a waterproof ceiling with its own integrated gutter network, which diverts water from the deck's surface to the perimeter. Connecting this new system to old, mismatched gutters can disrupt water flow, causing potential problems. New, custom gutters ensure a perfectly coordinated drainage system.

• Preventing leaks and clogs: Under-decks funnel large amounts of water to the outer gutters. If existing gutters are worn, cracked, or improperly sloped, they may overflow and cause leaks that defeat the purpose of the underdeck. Older systems are also more prone to clogging, which can cause water to back up and damage your new installation.

• Matching capacity: A new undercover system can increase the volume of water directed to your gutter system. An older gutter system might be undersized for this new, more efficient flow, leading to overflows during heavy rain. Replacing them ensures your entire drainage system can handle the load. 

For protection and durability -

• Avoiding water damage: Malfunctioning gutters can cause water to pool around your home's foundation, potentially causing expensive erosion and structural damage. Water overflow can also damage your new underdeck and other parts of your home's exterior, including siding, paint, and landscaping.

• Protecting your investment: Your new underdeck is a significant investment. Installing a new, long-lasting gutter system at the same time protects that investment by ensuring it is complemented by a reliable and effective drainage solution.

• Ensuring compatibility: An underdeck system directs water into a perimeter gutter below the deck. If you keep old gutters, you risk incompatibility with the new installation. It is more reliable to install a seamless system with new gutters designed to work with the underdeck. 

For cost-effectiveness -

• Saving money and time: A contractor may offer a discount for bundling the installation of a new underdeck and gutters at the same time. Combining the projects saves money on labor and reduces the disruption of multiple construction projects on your home.

• Avoiding future problems: Replacing old gutters prevents the need for another project in a few years when they finally fail. This proactive approach saves you from dealing with repair costs and the potential for water damage caused by old, ineffective gutters.

• Boosting home value: Upgrading both your underdeck and gutter systems at the same time is a smart home improvement that enhances your home's aesthetics and adds value. 

For a clean and finished appearance -

• Enhanced curb appeal: A new under-deck with old, worn-out gutters can look mismatched and detract from your home's appearance. Upgrading both provides a cohesive and modern look that increases curb appeal.

• Seamless finish: Many underdeck systems use integrated gutters that blend seamlessly with the ceiling panels. This integrated design provides a cleaner, more finished look compared to attaching a traditional gutter to the new system
