Roofing A Deck

Roofing an Existing Deck

Can I put a roof on my existing deck? This is the most frequently asked question when it comes to building a deck.  

If you want to enjoy the outdoors from your backyard while being protected from the sun or rain, roofing your deck is the perfect solution.

 

Why should I build roofing for my deck?

REASONS FOR ROOFING A DECK

As you can imagine, roofing your deck offers many benefits. Here are the top reasons why you would want a roof for your deck:

 

PROTECTION FROM SUN AND RAIN

The most common reason for roofing a deck is to protect it from the sun and rain. A roof allows you to sit outside and enjoy the outdoors, even on the sunniest and rainiest days. 

A shady spot on the deck is the best method for you and your loved ones to relax when the summer heat is at its highest.

 

GRILLING ALL YEAR ROUND

When you cover your deck, grilling season doesn't have to end with the last of the fireflies. You can grill all year round, even when it's not warm and dry. 

In the cooler months, it may take a little longer for food to cook, but it's worth it when you can enjoy delicious burgers, ribs or grilled vegetables.

 

DRYING LAUNDRY OUTSIDE

If you prefer to hang your laundry outside to dry rather than throw it in the dryer, a roof over your deck is the perfect solution for rainy days. Drying laundry out under the roof can save you money on electricity costs.

 

HELP PLANTS GROW

Green thumbs happily grow under a covered deck when spring arrives. You can get seedlings and plants used to the conditions by placing them in a sheltered spot and making sure they get some sun each day.

 

The three types of deck roofs

The type of roof you install depends on the kind of deck you have, its size, your personal preferences and more.

 

There are three types of roofs for decks: shed, gable and hip:

 

1. SHED ROOF

A single, sloping surface begins at the house's exterior wall and ends at support posts. 

It is well suited for long and narrow decks but not for deep because the slope is too steep.

 

2. GABLE ROOF

A Gable roof is the most common form of deck roof. 

It is triangular, runs along a ridge in the middle of the deck and overhangs the enclosed space. 

Unlike a flat roof, this significantly sloped deck roof allows for good drainage of rain and snow. A gable roof also blends well with many architectural styles.

 

3. HIP ROOF

This roof has a lower slope and requires a more complicated support system, but its solid, compact appearance makes it more aesthetically pleasing.

 

How to roof an existing deck?

Determine if the deck is suitable for a roof: Before starting work, make sure the deck can support the new roof's weight and any winter snow load.

 

Step 1: Measure the deck for the roof work

Firstly, you need to measure the deck, and the measurements will depend on its shape and length. For example, measuring is always easy with a rectangular or square deck because you only need to measure the height and width.

Shapes like trapezoids and pentagons are more complicated, as there is no apparent width or height measurement for them. So instead, take any size and multiply it by 3 (for example, if a pentagon has 2 x 3-foot sides, its base area is 2 x 3 feet). 

Alternatively, you can divide the deck into sections, measure the area of a section, and multiply that by the number of sections. 

Once you gather all the measurements, you can draw them on paper and use them as guides for cutting your roof boards.

 

Step 2: Check the roof framing

Make sure there is no indication of rot or decay that could compromise the structural integrity. If there are such signs, you may need to replace some framing parts before applying the roofing.

 

Step 3: Install the rafters

Decide on the type of rafters and install them according to the manufacturer's instructions. Be sure to space them properly so that the rafters run in a straight line and have a good overhang at both ends of the frame.

 

Step 4: Prepare the decking boards

The lengths must be determined according to the rafter spacing and cut to fit between the rafters and form a straight line.

 

Step 5: Install the decking boards

Use appropriate screws/nails or adhesives to secure each board with minimal gaps, ensuring they are correctly aligned for best results.

 

Step 6: Complete the frame of the eaves

Add any finishing touches at this time, such as fascia trim, before proceeding with any final work, such as roof shingles or tiles.

 

Step 7: Install the roofing materials

Have the roof shingles or deck roof tiles cut to the correct size and install them according to the manufacturer's instructions for best results and a finished look.

 

SAFETY CONCERNS

Without proper planning, a roof addition to an existing deck can be unsafe. A regular deck can support a certain weight per square foot, but a covered deck has a heavier weight and must be supported. 

In most cases, a covered deck will require larger footings and sometimes more foundations.

Therefore, it is best to install the roof when you first build the deck. If you want a covered deck, you should build the deck to be well supported, whether you choose to put the roof on first or later.

If you simply build a roof to a deck that is not designed for it without proper retrofitting, you are putting your family members and guests at risk.

 

Important FAQ about deck roofing

 

WHAT IS THE ROOFING OF A DECK CALLED?

The roofing of a deck is usually referred to as a patio cover. This attached structure protects from the sun and rain and can have either a fixed or open roof. 

Pergola is another name for patio or deck covers. It is usually an open roof supported by posts or columns. They provide filtered shade for outdoor living areas.

 

WHAT IS THE COST OF BUILDING A SHED ROOF OVER A DECK IN BRISBANE?

A shed roof is defined as a single slope roof that usually has a steep pitch. Shed roofs are commonly used for decks and patio areas. 

As with other building projects, the cost depends on various factors but typically ranges from $1,000 to $10,000 for materials and labour.

 

SHOULD I COVER MY DECK IN THE WINTER?

It is important to cover your DECK in the winter to protect it from harsh winter weather. 

You can choose between a permanent cover and a temporary tarp, but you may want to build a roof to make a long-term investment.
