Rooftop decks are a great way to take advantage of otherwise unused space. They offer a place to relax and unwind, enjoy beautiful natural landscapes or city skylines and host parties or al fresco dining. However, before you can enjoy any of these perks, it’s important to understand the basics of roof decking and how it works.
The most basic definition of roof deck is the structural base of the entire roof system that shingles and other roofing materials attach to. It also protects the structure by distributing weight evenly and keeping moisture from penetrating into the home’s interior.
To ensure the longevity of your rooftop deck, choose a high-quality material that can stand up to weather and sun exposure. You’ll want to select a composite or hardwood product that is durable and easy to maintain. Also, be sure to incorporate a drainage system to keep moisture away from the deck surface.
If your deck isn’t insulated, consider adding an insulation layer to the underside of the roof. This will help to prevent heat from escaping during the summer and cold from entering during the winter. It will also improve the energy efficiency of your home and help to reduce your utility bills.
Inspect the condition of your roof deck on a regular basis. This will help you catch any issues before they become serious problems. Look for sagging or unevenness in the roofline, which can indicate structural issues within the decking. Look for areas that feel soft or spongy underfoot, which may indicate rot or other damage. Also, gently walk on the deck (if it is safe to do so) and pay attention to any areas that seem to be shifting or sagging.
When choosing a roof deck material, it’s best to stick with the type specified on the project’s structural plans. If there is no specification, an engineer can help you determine the proper type of roof sheathing for your job. Type N is an excellent choice for long span conditions, while type B is a good option for short span situations or budget considerations.
Once you’ve chosen your roof deck material and layout, it’s time to start laying the boards. Whether you’re going for a classic wood look or something more unique, there are plenty of design options. For example, you can create an interesting pattern by staggered boarding or use a herringbone or diagonal arrangement to add visual interest. You can even add a picture frame edge to conceal the edges of the boards and provide a finished, polished look. Whatever your preference, be sure to include sturdy railings as required by international building codes.
