New Deck Cost By Material

Installing a Lean-to Roof on an existing Deck

There are many materials to use for a deck. Many people opt for wood or composite, but there is a wide range of materials that fall into those two categories. You can also use other materials, such as metals. Each material has costs and attributes influencing the appearance and long-term performance:

Install Gutters And Downspouts

If you want to install gutters for your under deck ceiling, plan ahead and leave space for them. You may have to get creative to come up with an attachment method, depending on how your deck is built. Since the in-stock 12-ft. panels didn’t quite reach the beams on Rune’s deck, he nailed vertical 2x4s to every other joist to provide an attachment point for the gutters. Then he screwed the gutter hangers to the 2x4s. Slope the gutters toward the downspout for drainage.

Measure The Deck For Roofing Works

The first thing you will need to do is measure the deck, understanding that the measurements will depend on its shape and length. For example, measurements for a rectangular or square deck are always easy as you just need to measure the height and width.

Shapes like trapezoids and pentagons are more complex because they lack an apparent width or height measurement. Take any size and multiply it by 3 .

Alternatively, you could divide the deck into sections, measure the area of one section, and multiply this by however many sections there are. Then, as soon as you have all your measurements, you can draw them on paper and use them as guides for cutting out your roof boards.

Attaching A Deck Roof Changes The Required Permits

The most straightforward deck roof construction beside your house is to attach it to the house. But this is a no, no regarding deck roofs. Attaching a deck roof to the house changes the required permit into an addition. A house addition is a much larger permit application and fee. The construction permit must include a development permit as you have now changed the look of the neighbourhood.

It is attached to a house.

This additional permit is partly to blame because of the ease of transforming a covered deck into a sunroom. Or I have even seen covered decks be enclosed with walls and becoming an extra room on the house. Which is what the city is trying to prevent, unpermitted decks becoming poorly constructed house additions. Decks with roofs need additional structural construction but still do not meet the requirements for a house addition. In the past to many have been given an inch and taken a foot. Now we all have to pay the price.

Now that you know some of what is required for a deck roof. If it is feeling like too much. Here are some deck shade alternatives.

Type Of Post Framing And Cost Of Materials

Adding a roof deck on your campers

The basic framing involves posts installed on the deck and cross beams at the top of the posts. For smaller deck projects, only corner posts may be required.

The weight that the posts and beams must support will determine the number needed and size. Generally, 6x 6 pressure-treated posts support most simple deck roofs.

The height of the beam is also a cost factor. A 6x 6 by 8southern yellow pine post currently costs between $30-$45. If the roof is being attached to the house, a ledger board must be installed. However, generally only half the number of posts are needed for a simple square or rectangular attached roof.

The type of post and beam materials are another cost factor. Many structures are made of redwood or cedar to complement a wooden deck. While more expensive than pine, they are not as expensive as vinyl or fiberglass.

Post mounts, braces, and joist or truss hangers are additional cost factors in this stage of building. For both framing and roofing, nails, screws, nuts, bolts, and tools need to be figured into the cost.

Roof Is Able To Support Adequate Weight

Determining how much weight your roof can support is a job that should be left to a professional engineer or architect. Miscalculating the strength of your roof can result in grave damage and even death.While local building codes vary from state to state, the minimum requirements typically state that your roof needs to support at least 55 pounds of weight per square foot.

However, the necessary strength of your roof will also vary depending on how you plan to use the rooftop deck. For instance, if you plan to add a hot tub or other heavy furniture, you will need to account for the added weight in the design of your rooftop deck.

Even if your current roof is not strong enough to support the additional weight of a rooftop deck, there may be ways to strengthen the existing structure. You can read more about how to reinforce your roof strength here.

Select Your Rooftop Deck Framing

The basic options are sleepers, wood framing or adjustable pedestal systems.

  • Sleepers. Sleepers are less costly up-front, but they have pros and cons. Check out this article on installing sleepers for a better understanding.
  • Wood Framing. Traditional wood deck framing is an option, too. The benefits are also a low-cost option, up front. The downside is they may potentially be too heavy for your roof to support the extra weight. Because a low-clearance rooftop deck is a harsh environment, wood joists may warp, twist or rot.
  • Aluminum Joists. A high-performance adjustable pedestal system with aluminum joists is more expensive up front. However, they will not rot, warp or twist and they are non-combustible.

Rune bought corrugated fiberglass panels at a home center to use for his under-deck roof. The panels he used are 26 in. wide and 12 ft. long. He attached the panels with special roofing screws that have hex heads and neoprene washers for sealing. Youll find these screws where steel or fiberglass roofing is sold. You could also use galvanized steel or plastic roofing panels and install them the same way. Rune screwed treated 2×4 purlins to spacer blocks to support the panels and provide the necessary slope .

Gutters arent required, especially if the water drains onto your lawn. But if the water falls onto the patio, gutters can prevent splashing. Rune chose PVC gutters because theyre inexpensive and easy to cut and install. If you decide to install gutters, youll need lengths of the gutter, gutter straps, end caps, a downspout outlet, downspouts and special glue to join the sections.

How To Add Porch With Gable Roof To Match Existing Architecture – Framing Detail Examples

We wanted to build a roof over our entire deck but the cost was too high for our budget. So, we decided to buy a Backyard Discovery 12′ x 10′ Brookdale Gazebo kit from Sam’s Club. This gazebo kit completes our 2021 deck makeover! This hard top gazebo kit was easy to assemble and had easy to follow instructions but there were struggles when installing it on top of our deck. I had to brace the existing deck to prevent it from collapse. We also had a very hard time getting the roof sections on top of the assembled gazebo. The instructions stated it would take two adults. But we had five people to put the deck roof on and still had struggles. Of course, it likely would have been easier if the gazebo had been installed on a slab or on the ground.
