Would it be stupid to design a deck at a small angle (say maybe 3 degrees) so that rainwater runs off and does not rot the wood?

Decks have gaps between the boards. Boards have a slight cup to them. Install them cup side down.

this is against code, rainwater must collect where the deck meets the house and into the basement

Hello, I am a professional deck engineer

Just make a proper roof (>10°), that is the minimum tilt for water to run off shingled roofs.

For the foundation, use rough lumber. This is more resistant to rainwater because trees last in the wild for decades, while 2x10's don't even grow in nature because they are weak.

If OP is wanting to turn rainwater, it's because HE DOESN'T WANT A FUCKIN ROOF OVER HIS DECK!

(Expert) doesn't know the difference between a frame and a foundation
For the foundation, use some type of masonry.
For the frame, use treated material
There are joist caps of metal or plastic to apply before decking to prevent what happened in OP pic

Old houses have porches like this. They were built at a very slight angle.

that looks really complicated and expensive. What about just using old railroad ties and make the posts out of phone poles? Or all raw fresh wood and seal cote with creosote or driveway sealer? Or use roll roofing as the deck surface in general? Have you ever tried this?

You know that shit burns like gasoline and it very difficult to put out? But hey, yeah, let's build the thing we're going to have the BBQ on out of it and nail it to the side of our house.

Yes, that's because they typically used a tongue & groove board that didn't have gaps between them, so they needed a slope for water to run off. On a deck it is not an issue because there are gaps between the boards.

I have a 3m long wooden deck. I lowered the end by 1.5-2cm and the rain water flows down right away and you don't feel like you are on a ghost slope. It feels just natural.

Well i made my parking space out of pulled up railroad ties before and got $60 each for the tracks at the scrap yard. so it actually cost -$120 discounting gas and labor. in hindsight I probably broke even because it took about 10 hours.

Nah. Give it a one degree slope and install plastic catchers between your hung joists. Tie that all into a gutter system running to a French drain. Hire professionals. No water ever. After the wood deteriorates anyways because winter, realize you can build the thing out of PT and you'll have to replace it anyways. Remember your 16" on center.


You'll definitely want to cut your stringers at a 15° slope though. Stairs are the most susceptible to water and rot.

They last way longer than that. This one time I planted a tree and it's still alive 115 years later.
And bonsai trees in captivity can last centuries.

Or use a stick and peel membrane on the top of the joists if you have the dosh.
