In a lot of areas, if it is less than 2' high and not attached to the house the deck is considered landscaping and building code does not apply. Check your local code/regulations/bylaws. I am not fond of mixing deck blocks/piers with proper footings. I think weird things could happen when the ground moves from frost, etc. That being said, if the deck is ...

Would I use a contractor? Yes. Would roofers be able to weigh in on it? Not really, you want a surface people will be walking on. You'll want someone with specific carpentry knowledge. A general contractor, a framing contractor, or better yet a deck-building contractor would be better. My advice based on your photos in the comments: The beam ...

Using the old footings sounds fine, so long as they've done their settling or were poured off kilter to begin with, it's those new ones I'm not too keen on, that will just sit on the ground. If you are going to use pier blocks, you might as well use the old questionable footings; can't be any worse then just using a rock. You mentioned frost which means ...

What are the joists made out of? How far apart are they? "Looks really solid" isn't a very scientific assessment. ;-) If the joists are wood, what kind are they? Are they suitable for wet outdoor conditions? Or is the deck going to be sealed so that the joists never get wet? You want to start by determining what kind of wood the joists are made out of to ...

Most mills do not produce and sell treated wood rated for contact with the ground, so any wood in your deck that will be in contact with the ground should be treated, and gotten wherever it is to be got. Buying wood from a mill is often cheaper, though it is not always. A smaller operation with a smaller economic influence (like most mills open to the ...

The problem with the pipe idea is that unless you're going to run it at an angle, you'd never be able to get a pipe through several consecutive rafters. You may actually be OK with lag screws - a properly installed 3/8 lag screw should provide an enormous amount of withdrawal resistance. Here's a sample chart from Masco:1 I wouldn't be horribly ...

How are you joining these 2x12's? Who has done the load and deflection calculations to ensure that a 3.5" x 11.5" x 40' wood beam can handle the load you want to put on it? What kind of load are you expecting the finished deck to hold? Is this thing up in the air, or close to the ground? You've considered that your finished beam is going to weigh ...

Crown side down though helps prevent the boards from warping as much because the frame stops it from warping. Its easier for it to pull out the nails then it is to push through the frame
