Deck Cost in the Rogue Valley by Size
A new deck in the Rogue Valley costs about 30 to 60 dollars per square foot installed, so a 14 by 20 foot deck runs roughly 8,400 to 16,800 dollars and a 20 by 20 foot deck about 12,000 to 24,000 dollars. In the hot southern Oregon sun, composite and heat tolerant materials hold up better than softwood, which can dry, split, and get too hot underfoot.

Decking for the southern Oregon heat
Rogue Valley sun is hard on a deck. Intense UV dries and greys softwood fast, and dark composite boards can get very hot underfoot in summer. Pressure treated wood is cheaper but needs regular sealing, while quality composite resists fading and splintering. Lighter composite colors stay cooler, which matters for a deck used through hot summers.
