Protection Against Drifting Rain/ Winds

[THAIPHUKET]

I love to sit outside at any weather. My drive-in has a 4x5 meter roof, height about 2.30m , big enough to sit and look out on the river as long as the rain just falls down. To use simple translucent plastic tarpaulin which can be rolled up/down is probably not possible because the large surface area. It would make the tarpaulin like a sail prone to be ripped apart. Or very noisy.

I thought of using a net material. If the winds are strong rain spray would still come in but no heavy waters and the winds blow less strongly through.

This is how far my own brainstorming has brought me. Any suggestions? Don't want to wall myself in.

Pitch a camping tent on the lawn?

My feeling is any cover you put in to block the rain will act as a sail. The smaller the holes in the cover the less rain/spray coming in but the more sail area. The bigger holes allow more rain in but I think will not alter the effects of the sail effect enough to prevent possible lifting of the carpark roof. Of course if the carpark has a very strong footing/foundation/columns and roof then roof damage is not a factor just the tearing of the tarp canopy cover material.

Where I live we shaded our car park with the green plastic see thru netting normally seen on garden shops for shading plants. I surrounded three sides with it and the first really big wind almost blew our light roof off due to the sail effects of the netting.

I also enjoy sitting under cover to enjoy the rainfall. So you really don't want any sort of roll down screen even if transparent as it is just not the same as a completely unobstructed view. Do you have space to add a trellis for the problem areas. I plan on doing this for my house on 3 sides to block the sun from hitting walls and windows. Personally I plan on just building a simple support structure that extends horizontally from the eave to hold vine like vegetation that will grow and cover the area providing shade as I am not trying to keep out the rain.

But a proper trellis built with a slight slope and the top sheeted with clear plastic roofing should keep out most of the rain from angling in as long as it is extended out from your existing roof edge far enough. I would use simple small pre-formed concrete columns for the supports and build the cover of the trellis from conwood products and paint with an appropriate paint. I would even cover the concrete columns with conwood as well to make it appear to be a 'wooden' post.

Of course there will be significant cost and labour with this approach.
