In this article, we’ll walk you through how to build a rooftop deck, from choosing the proper joists and beams to installing a membrane that’s at least 1/4-inch thick. We’ll also talk about choosing shingles and decking materials. We’ll discuss some of the best practices for achieving a roof deck’s aesthetic appeal. And, as we’ll see, the process is much simpler and quicker than you might imagine.

How to Build a Roof Deck on a Pitch Roof?

Installing joists and beams

Before you start installing joists and beams to build your roof deck, make sure you follow the proper installation method. You can use a hold-down system to secure the beam to the roof deck foundation. Place the beam over each pair of sill plates. Next, install hold-downs in each beam on either side. Drill holes deep enough for a threaded rod.

Before you begin installing joists and beams, you should prepare the roof for the deck. First, install plywood sheathing and if possible, insulate the space between the rafters. Next, install beams and joist hangers. You may also want to install flashing underneath the deck. To build a roof deck, you can consult a contractor.

To use a stud finder, hold it several inches away from the wall. You must calibrate the device according to the manufacturer’s instructions. When you run the joist finder, make sure that it illuminates when it hits the edge of the joist. The stronger the signal, the closer you are to the centre of the joist.

You can also use an overbuild to support the deck flooring. This structure floats over the roof. During installation of the overbuild at Hudson Gables co-op, the project was supervised by Cowley Engineering. The board of directors wanted a freestanding elevated deck facing the Hudson River and the George Washington Bridge. Despite the high-rise co-op building, it is still possible to install a roof deck on a pitched roof.

Installing membrane with minimum 1/4-inch-thickness

The NRCA roofing manual and the manufacturer of the membrane specify the specific installation guidelines for the membrane you choose. Generally, the membrane should be installed with at least a quarter-inch thickness on a pitched roof. You should also follow the manufacturer’s instructions for fastening mechanical equipment, such as flashings, with neoprene washers.

If you’re installing a single-ply roof, the NRCA suggests installing a minimum of one-fourth-inch-thickness asphaltic membrane. In the U.S., this standard is 2%, but your local codes may require more or less slope, so always consult your building plans before installing a new membrane. As a result, you’ll reduce the possibility of ponding and ensure a proper installation.

Most membranes require a capillary break layer. This prevents water from sitting on the membrane, which leads to its degradation. Hot rubberized asphalt, on the other hand, does not require this layer. This material is impervious to standing water. This prevents any leaking from occurring on the roof. But you should also take into consideration the odor management.

It is important to install a drainage mat. A good drainage mat is woven, whereas a dimpled or high-hat type of membrane can reduce R-value. Make sure the drainage mat has a sufficient compressive strength to support the load of the roof. A drainage mat is a good way to prevent leaks from forming. When installing a waterproofing membrane, be sure to include the details of the pitched roof in your plans.

Choosing the right decking for a rooftop deck

There are a variety of hardwoods available for a rooftop deck. You can choose from light to medium brown wood with sophisticated figuring. If you plan to build your rooftop deck on a pitched roof, choose hardwoods that are able to withstand strong UV exposure and extreme weather conditions. You can also select woods that are FSC (r) Certified. Ipe wood and Mataverde Machiche are two choices for wood decking, and both are durable and beautiful.

Hardwood is an option for the decking material, but it requires a higher-priced installation. Pressure-treated wood is also heavy, and you’ll need at least 12 inches of clearance for the deck to be built. Hardwoods are dense and durable, but they’re expensive and not very eco-friendly. Another option is modified wood, which has few maintenance requirements and is resistant to moisture and sun.

If you want a more rustic, traditional look, wood is a great option. However, wood tends to be more expensive than other materials, and the maintenance requirements are higher. You can also choose waterproof membranes to protect the deck from moisture and provide a linear, neat surface. You can also choose from a variety of tiles and sandstone for a low-maintenance option.

In addition to pressure-treated wood, you can choose a steel or aluminum frame for your rooftop deck. This will prevent you from having to replace the decking boards before the steel frame is replaced. In addition to these benefits, steel frames can be more durable and last for longer. Fortress Building Products is the industry leader for all-steel rooftop decks. On the other hand, hardwood decking is more expensive and will need frequent maintenance.

Depending on the style and budget of your home, choosing the right decking for a rooftop deck can be tricky. You may want to consider a waterproof membrane that can withstand multiple directions of slope, including the deck itself. Raised seams in the waterproof membrane will also need to be considered. Once you’ve chosen the right decking for your rooftop deck, you can start planning the rest.

Choosing the right shingles

Choosing the right shingles for your new roof deck project is essential for ensuring that your deck will blend with your home’s exterior. Colors can vary widely depending on what kind of roofing material you use. Standard asphalt shingles come in black or gray, while slate tiles are neutral whites or grays. Metal can come in a variety of shades and textures, so a darker color may look best with off-white or red brick siding. It’s best to use a paint sample to match the color of the roof before you purchase shingles.

Color is important as well. Lighter colors reflect heat while darker colors absorb heat. However, keep in mind that energy efficiency is based on a home’s proper insulation and ventilation. Certain states require highly reflective colors in roofs to meet environmental codes, so you should consult a local roofing contractor to determine which color best suits your house. If you have a tar-and-silver roof, make sure that it will match the colors of the exterior of your home.

Another important factor to consider when choosing shingles is the dead load. Shingle materials vary in weight and impact resistance. This is important because hail damage can compromise the waterproofing of the roof and cause water infiltration, leaks, and even mold. Because hail is invisible, you may not notice damage to your roof until you see it, and you may be under the impression that it’s not damaged at all.

Choosing the right color shingles is vital for the aesthetic look of your roof deck. While white shingles are often the most popular option, you should choose a shade that blends with your home’s existing siding. Consider the color of the roof to avoid a clash of colors. A white roof is a perfect canvas for a variety of accent colors. Consider a medium-dark gray color that has a slight bluish cast. Grey or blue shingles are complementary to white shingles, but they can clash if the roof deck is attached to a home.

While choosing the right asphalt shingles is crucial for a roof deck, a dark or light shade of a particular color should blend well with the surrounding area. The shingle color can help you express your personality and add a warm, inviting vibe to your home. You can also choose from several color shades to complement your landscaping and natural surroundings. You can even choose to paint the roof deck to match your home’s colors, but be sure to make the decision based on what you love.
