Radon mitigation system side vent to roof vent

Hello

I have a fully functional radon mitigation system inside my basement. The vents into the backyard at ground level. I bought the house recently like this. The radon levels are normal.

I understand that per code-- the vent needs to be extended up to the roof (and not at ground level), so I contacted a radon contractor. They came back with a quote of approximately 2000$ to basically replace the whole system which will vent up to the roof level.

All i need is a pipe that will extend the current ground level vent up to the roof.

Do I really need to replace the whole system for this?

Thanks

Where is your motor head located? Can you post a picture of your installation so we can see what you see? Moving the motor head up above the first floor away from any operable windows is sufficient. You just need it to evacuate the radon gasses into the atmosphere away from personnel.

Yes I did have a home-inspection and they recommended taking the vent upto the roof.

The motor head is located inside the basement.

I have attached the pictures of the body of the system inside the basement and the vent out in the backyard.

The system works as radon levels are acceptable.
just need to extend the vent to the roof--wonder how to do it/who to call. I will also get a couple other quotes
Thank you

Is the Radon company in the picture the same that gave you the $2,000 estimate? If it is, it's clearly a scam and should be reported to the BBB if not the law. Is that mold under that insulation?
Have you taken a radon reading without the system running? It may not even be needed. This has some good reading.

We mount the ones we install on the outside of the building, up high with a rain cap attached to the housing. They don't usually go above the roof line to shield it from weather. It is weathertite, but everything helps, plus you aren't punching a hole in an otherwise non leaking roof.

I think they are going more for the roof because houses suck. Houses are drawing replacement air and intake air in the attic . If there is moisture in the discharge air, that is sucked into the attic, that can cause other problems.
If you go up thru the house you also have to air tight seal at every floor and ceiling.
