Correct method for Patio deck attachment to roof


After you demolish the old deck but before you start work on the new one, you'll need to make sure the wood on and in the house is still in good shape. Water leaking around an old deck ledger can cause significant damage to the house framing. The existing house rim and the lower support walls need to be solid enough to support the multi-ton weight of a deck filled with people. After the old deck is removed, you'll be able to tell if you can still use the house rim. If the wall sheathing behind the rim looks good, you're okay. But if the sheathing is rotten, investigate further by removing the rotted areas, and check the house's rim joist and wall framing to see if they're rotten too. Don't be too eager to rip apart and replace moist or discolored wood; it may still be intact below the surface. Jam a screwdriver into the wood in several places. If the screwdriver penetrates more than 1/4 in. or so, it's replacement time.

This article is a continuation of the article: Building a Roof Over a Deck or Patio.

Rafters spread patio roofing loads across beams, making it possible to use roofing materials too insubstantial to span the distances between beams.

Rafters must support their own weight over open space without sagging or twisting and also support the weight of the roof covering. For a roof that must shed water, they are sloped. Rafters may connect to ledgers and beams any of several ways. The right method to use depends on the roof’s design. For proper spans and spacings of patio roof beams and rafters, please see Patio Roof Maximum Beam & Rafter Spans.

Decoratively cutting rafter ends can give a patio roof or gazebo a distinctive style. If you wish to add decorative detailing to rafters, do so before you lift and fasten them into place. Use a saber saw for making curved cuts.

I agree with Ed Beal. But yes, there are 2 ways to do this & they're equal in strength, for what's planning to be done. However, get a Permit from the Building Dept., so they can approve or correct the design, fasteners & supporting post(s) dimensions & footings. Plus, they can record that the patio was converted to a porch.

1st way is to do ledgers on both fasciae into structural members. Typically you'd pre-build the new structure so the short rafters are end screwed or nailed through the blue-line's ledger & the long lower beam & top ledger are through the side ledger (rafter). Also, use joist hanger type connectors to ensure nothing can pull away from each other.

2nd way is really the proper way & is likely what the one contractor was talking about. You'd remove both fasciae & screw or nail directly into the structure. For the slope side this is much less important. But, the blue-line top would have the new rafters cantilevered or sistered onto the home's existing...

Transformation Deck & Fence

Benefits of both oil and acrylic

Newly launched in 2012, Transformation Stain Deck & Fence combines the benefits of both oil and acrylic deck stain technologies into one stain. Acrylic deck stains provide great wood surface protection but do not penetrate the wood surface. Eventually, acrylic stains will peel from the surface in patches, making re-staining difficult. Oil deck stains penetrate well into the wood but do not always leave adequate protection at the wood surface. Transformation Deck & Fence penetrates into the wood for great adhesion but also leaves protection at the surface to battle the sun, moisture and foot traffic.

The stain erodes instead of peels and wears evenly across your deck for easy maintenance. Combine that with water clean-up and it is among the easiest stains to maintain. Visit

Basic, Important Considerations in Planning a Deck Attachment to House

Envision the size you would like and that fits your family's needs. Then measure the house wall on which you plan to attach the deck. Determine the sun, shade, and wind that will affect deck's placement and make plans for any additional enhancements, i.e., latticed cover.

Sketch a plan of the deck with dimensions.Check with your local building department to verify that the design meets all local building codes and requirements. If OK'd, you may pay a fee for a building permit with a time limit. An inspector may visit to examine your construction. This varies from community to community. You may want to review your design with an architect.

3 Ways to keep dry under your deck

If you want to buy a manufactured system rather than build your own as we show here, you have a lot of choices.

1. One option is to cover the deck boards with a watertight membrane. DeckRite makes a deck floor covering that has the added advantage of creating a dry space below the deck. For more information, visit

2. If you're building a new deck or replacing your deck boards, you can use a system like Trex RainEscape, which installs in the joist spaces before you install the decking. The advantage of this system is that it allows you to easily add lighting or other wiring in the joists, and cover the bottom of the joists with bead board or any attractive ceiling finish you choose. Learn more at

3. If your deck is already built, you can cover the bottom of the joists with a system like TimberTech's DrySpace. One advantage these systems have over simply screwing roof panels to the bottom of the...

I have a stucco house and want to build a very simple cover over a patio. Right now, the patio is simply dirt, but I plan to pave it in the near future. I need the patio cover on before I pour any cement for obvious reasons.

Not sure what I'll use for a cover - probably something fairly cheap and inexpensive. I MIGHT use some sunscreen "mesh" that I used to cover our playground set - Hot here in Phoenix in the summer. It was very easy to build a wood "frame" over the playground and then tightly drape and use these simple "staple plates" to attach the green mesh to the frame. Used pressure-treated wood so it'll hopefully last in the hot sun. The mesh would be nice over the patio because it would let the hot air (and BBQ fumes) out but keeps the hot sun out. The disadvantage is that it lets the rain in. Thought about doing half the patio cover using some simple roofing material and the other half in the mesh.

So - the Pro's and Con's of each option - attach to house versus...

The weather is beginning to turn and the days are getting shorter. The golden rod is beginning to appear along the sides of the roads. The commercials advertising back to school sales are beginning to appear again on television. Like it or not, the fall is quickly approaching and right behind it will be the winter. Along with the winter comes snow fall.

Knowing that old man winter is rapidly approaching, you begin to walk around your home doing a quick inspection of the exterior. You are looking for those last minute repairs and clean-up projects that will save you a much bigger project later on. As you are looking at the roof on your home, you glance over the metal roof on a lower porch and recall the heavy snow fall from last year. You also recall the avalanche of snow that came off of that roof crushing the patio set that was being stored just below it.

Metal roof systems are prone to snow build-up and snow sliding. This is because of...

Deck Ledger Board Flashing Detail

Lately I’ve been seeing problematic deck ledger flashing details so I’d like to share with you my perspective on how to properly flash and secure your deck to the house. Properly flashing a deck ledger seems to be a lost skill with most weekend warriors…..let’s discuss how to properly secure the deck ledger and install the flashing.

Building a new deck isn’t really that difficult of a project. However, there are some details that must be followed in order to prevent premature failure of your deck and the area of your house that it’s attached to. The problem with attaching a deck to the house is it creates a great area to collect water. The intersection of the house and deck is extremely vulnerable to moisture problems.

As you can see from the diagram and the photo flashing must be done in layers. The best way to think about it to visualize what a drop of water...
