Portland and Vancouver get roughly 155 rainy days a year. Between that and the winter weather, if you have an uncovered outdoor space, you can realistically use it about four months a year. If you have a covered one, that number doubles. That math is why covered patios are one of the most consistently requested outdoor projects we see, and why the question "how much does a covered patio cost?" comes up in nearly every outdoor living conversation we have with homeowners in this area.
