Retractable tents are a great way to enjoy your deck or patio as the sun goes down and no other buildings or trees provide shade.
Another option – not so well known – is to put a tent on your roof. This is necessary when there is not enough space above your door or window. You can search more information about retractable roof through http://coversinplay.us/retractable-roof/.
Roof installation is very simple and straightforward. To mount the roof you will need special brackets. This should be an option when ordering a tent. Also, it is very similar to standard wall mounting.
Ensure that when you attach the brackets to the roof with safety screws, you are getting a security fix to the roof beams, just as you would normally do with your walls.
Before attaching the brackets to the roof, apply a gasket around the holes, also known as a back gasket. Do not use regular bath sealants. Use an external sealant that can withstand temperature changes.
Another consideration is this: if you put a tent on your roof, get a tent with a very deep projection. You "loosen up" each ledge like the one on the roof and therefore concave it into your deck.
One more thought. Generally, the roof canopy needs to be driven by a motor as you will most likely not be able to reach the tent with a manual crank. This makes the canopy more expensive and you have to plan for an electric one.
