We have the canvas over the birdcage and an adjacent roof covered lanai. The bird cage cover works well, but needs to be replenished every few years due to wear and tear from rain, wind and sun. It has held up very well in hurricane force winds. It does make a drumming noise in the very high winds. I don't understand the comment about heat under the canvas - there is no difference in temperature between the birdcage and the lanai. I would do it again. I recommend Sunshine Awning. They stand behind their work.
