I have a home with T-11 Siding...this is like a plywood with 1 inch groves in like panelling.

The deck board but up to this siding, and I have found out that it has rotted out, and I will have to replace the siding that come in 4X8 sheets..but after I get that done, how do I keep this from happening again? what happens is the dirt and stuff get in the groves and then sit there and rot the wood...it was painted and such and the deck is pressure treated...


Thoughts...thanks...
