Question about Honda Ridgeline
Couple of possibilities. First is, you may have a small leak in the heater core. This is a small radiator- type device where the engine coolant flows through and extracts the heat from the engine to warm the cabin. The quick check is to check your coolant level in the engine compartment at the coolant overflow bottle (the bottle where you add engine coolant, see your owners manual for tbe location) and see if its low. A second test is to wipe your fingers across the wet spot and "taste" the liquid. Coolant has a sweet, sticky taste.
The second possibility is that the HVAC core housing drain, is plugged. When you operate your air conditioner, it extracts moisture from the air and this collects in the bottom of the housing. It runs to the lowest point and then out of a drain to beneath the car. If this drain becomes clogged (not all that uncommon), the condensate will continue to collect and eventually overflow into the cabin floor. Usually this occurs in the drivers floor well but it can also collect on the hump first and then flow downwards into the floor well.
A simple check is the run the a/c on a warm, humid day and see if theres any condensate draining out under the car.
The clear this, you will need to crawl under the car and look near a point where the hump joins the firewall on the drivers side. You will be looking for a small rubber part which has a "flapper" valve on the end. Run a piece of soft, flexible wire material (like a pipe cleaner) backwards up the drain and see if you can knock the blockage loose. The other option is to blow compressed air into the drain (I would use a can of compressed air with a straw) and see if that clears the drain.
This YouTube video shows how to do this as well as follow up with a product called "Kool It" used to clear the mold that nearly always results when this happens. You can buy "Kool It" on Amazon.

Check the seals over the welds on the top roof rail area.

It can be quite a few things Lisa, but the most likely things are the windscreen rubber has perished, and letting in water (this would be more common on older cars). If your car is more modern, it will probably have a bonded screen. If so, has it recently been replaced? If so, it might be worth approaching the screen fitter to get the screen re-sealed under guarantee.
Run a hose over the front window for a while, while checking below the dashboard to see if you can see where the water is coming in.
There is also a possibility the drain holes in the windscreen scuttle may have become blocked. The scuttle is the bit between the bonnet and the windscreen. It usually has a grill cut into it.
If this is blocked, try to access the drain tube with a long rod to try and clear it out. A common occurrence if your car is regularly parked under trees / bushes, or in dusty areas. Sometimes, you may be able to see a puddle of water collected below the scuttle grill.
The worst result could be rusty floor pans. Most common on older cars. Very rare on newer cars. If you find the carpets become wet only after you have driven in wet conditions, then it is certain to be caused by rust holes in the floor. If you are unlucky enough to have this problem, it might be a good time to get rid of the car.
I can be repaired, but can be very very expensive.
For some very old cars (1960s to 1970s), you can find floor repair panels, but these are less common for newer cars.
You could also have a leaking sunroof. A good competent mechanic should be able to offer a few options to fix that. Start with a hose over the car, with kitchen roll over the carpet to help show up where the water is coming in.
