You would need to dig a footer and install some support for the extension. You can't just cantilever it over the concrete decking with no support underneath and not fastened to any supporting members tied into the concrete. You will also have to deal with the height issue. The deck will need to be framed properly, and that will make the resultant height above the threshold of your front door which can create moisture infiltration issues as well as access issues. Perhaps contact a local high school that has a vocational program and explain your situation. If you would be able to pay for the materials, perhaps they would donate the labor. I've known many who took on projects of this type in order to gain trade experience and do community service all in one project.

Here is my post earlier this week on MoccasinLanding's Hardwood Floors thread, with edits: Remember DH's declaration that we won't do any more major projects for the next three years following last year's 5 month and $30,000 foundation disaster? Well, we barely made it a year. The roof is really really really bad, the guys who cleaned my gutters said. We are looking at tearing off the 34 yo shingles, replacing some decking, doubling the amount of soffit vents and adding roof vents. We also may be removing all the decking from the area above the family room in order to insulate above the raised ceiling (it is sooo hot in there in the summer!). Fun fun fun. Last year's foundation disaster almost resulted in us pouring a "porch" foundation the same height as the foyer/laundry room for another 15 ft out from the front door so that when we re-roofed, we could extend the roof out over the porch to the end of the front room, which is DH's library and music room. Doing that, we could add a peak above the foyer and laundry room to change the path of the roof drainage. Then we just need to have Jim move the front wall out and drywall the new side walls and we would get a front closet and a laundry room big enough to work in. Didn't do it. (When I say "almost resulted in," it means that Jim (my contractor) and I were contemplating. DH was never on board.) Kick kick kick. Instead, we will continue to have a flat area on the roof above the foyer and laundry room and just hope that improved ventilation stops the snow from melting or sliding down the roof and icing up my porch and ramp. Stupid house designer must have been from the South. Who makes a roof designed to dump rain and snow in three different directions onto the FRONT PORCH in a cold climate! If we had extended out the front slab, we would now be adding a roof peak where the flat area is and the roof would drain to the sides. And I would have a laundry room big enough to fold in, and a front closet. We do have a coat closet in the middle of the house. It could be a utility closet now instead, if we had poured that slab out further last year......... My shins hurt. Friday, December 14 Yesterday I signed a contract to redo the roof. Today I stopped by their office to drop off a check for the first half of the payment. I talked with the manager and we discussed the venting further and the possibility of putting insulation above the cathedral ceiling in the family room. There was no way to get up there to insulate when we had the attic insulated because there was not enough room between the ceiling and the roof. So he will pull up some roof decking to check out the condition of the insulation there before re-roofing. He says that if we do need to insulate the room from above, he will do his best to make it fold into the cost of the roof job as much as possible, maybe just paying for the extra materials and a bit more. So that is the not-so-exciting news, we are getting a new roof. The picture you see below is from 2007, before we put in our front door, raised porch deck and ramp. We no longer have any shutters and the front windows have been replaced by Eagle windows with bronze aluminum cladding. The picture in the link has the new garden bed, door, and porch in it, but not the new windows. Here is a link that might be useful: A view of the front of the house with flat roof area

Greg, I probably wouldn't agree with your industrial safety policy. I'm asking how to step from the ladder to the peak safely, and you're proposing that I should do it by stepping from the ladder to the peak. What could go wrong? I measured the space from the drip edge to the ground where the space is narrowest, assuming I'd have to move the ladder the length of the roof, and I found that there wasn't enough space to extend it from the roof deck to the ground. But if I set up the ladder where the space is widest and skooch down the roof to the place where I need to work, I may have enough space. If that doesn't work out, the little home-built roof ladder is probably the best option. But it too will consume lumber that's already budgeted for other uses, and isn't replaceable until the pandemic is over. I wonder how much scrap lumber I have stuck in the corner of the garage.

@Indecisiveness, sorry if unclear. First pic are color samples described in the message.
