Deck Roofs

There’s nothing like enjoying the outdoors from the comfort of your deck, and adding a roof can make it even more versatile and enjoyable year-round. One popular option for deck roofing is clear polycarbonate roofing sheets. These sheets offer a sleek, modern look while providing protection from the elements. Here’s a guide on what to consider, how to take care of it, and the regular upkeep required.

Project Background

Recently, Rob and Robert took on a project to add a clear polycarbonate roof to a preexisting deck. The deck was older and weathered, requiring some repairs to the deck boards and railing to ensure a solid foundation for the new roof. The client preferred to leave the wood unpainted for now. We will see if we can get that painted and maybe rejuvenate the rest of the decks foundation.

What to Consider When Choosing Clear Polycarbonate Roofing Sheets

1. Light Transmission: Clear polycarbonate sheets allow up to 90% of natural light to pass through, creating a bright and airy environment. This can enhance the aesthetics of your deck and make it a more pleasant space to spend time in.
2. UV Protection: Look for polycarbonate sheets with UV protection. This feature not only protects you and your family from harmful UV rays but also prevents the sheets from yellowing or becoming brittle over time.
3. Durability: Polycarbonate sheets are highly durable and can withstand extreme weather conditions, including heavy rain, hail, and strong winds. They are also resistant to impact, making them a long-lasting choice for your deck.
4. Insulation Properties: Although clear polycarbonate sheets are excellent for light transmission, consider their insulation properties. Double-walled polycarbonate sheets offer better insulation, helping to keep the deck area cooler in summer and warmer in winter.
5. Aesthetics: The clear sheets provide a sleek and modern look. However, ensure that they match the overall design of your home and deck.

Installation Tips

1. Proper Slope: Ensure your polycarbonate roof has a sufficient slope to allow water to run off easily. A slope of at least 5 degrees is recommended to prevent water pooling, which can lead to leaks and damage.
2. Sealing: Proper sealing around the edges and joints is crucial to prevent water ingress. Use high-quality sealants compatible with polycarbonate materials.
3. Support Structure: The support structure must be sturdy and well-designed to accommodate the polycarbonate sheets. Consider using aluminum or treated wood for the framework to prevent corrosion and decay.
4. Thermal Expansion: Polycarbonate sheets expand and contract with temperature changes. Leave some room for thermal expansion during installation to avoid warping or cracking.

Tips for Taking Care of Clear Polycarbonate Roofing Sheets

1. Regular Cleaning: Clean the sheets regularly to maintain their clarity and appearance. Use a mild soap solution and a soft cloth or sponge to avoid scratching the surface. Rinse thoroughly with water.
2. Avoid Abrasive Cleaners: Do not use abrasive cleaners or brushes that can scratch the polycarbonate surface. Avoid using solvents such as acetone, benzene, or turpentine.
3. Inspect for Damage: Periodically inspect the sheets for any signs of damage, such as cracks, holes, or discoloration. Address any issues promptly to prevent further damage.
4. Clear Debris: Remove leaves, twigs, and other debris from the roof regularly to prevent clogging and water accumulation. This also helps in maintaining the aesthetic appeal of the roof.
5. Check Sealants: Inspect the sealants around the edges and joints periodically. Reapply or replace sealant if it shows signs of wear or deterioration.

Regular Upkeep

1. Annual Inspection: Conduct an annual inspection of the entire roofing system, including the support structure, fasteners, and sealants. Look for any signs of wear and tear or potential problems.
2. Clean Gutters and Drains: Ensure that gutters and drains connected to the polycarbonate roof are clear of debris. Blocked gutters can cause water to back up and damage the roof.
3. Trim Nearby Trees: Trim any overhanging branches that could drop leaves or cause damage to the roof. This also reduces the risk of mold and algae growth.
4. Address Algae and Mold: If algae or mold begins to grow on the sheets, clean it off with a solution of water and mild bleach. Rinse thoroughly to remove any residue.

By considering these factors and following these maintenance tips, you can ensure that your clear polycarbonate deck roofing remains in excellent condition, providing you with a beautiful and functional outdoor space for years to come.
