Is Your Roof Ready For A Rooftop Deck?

If you are dreaming of a rooftop deck to escape the noise and grit of city life, the first thing that you should consider is the condition of your roof. It would be expensive and troublesome to have a roof deck installed, only to have it removed for roof repair or replacement. If your roof is in bad enough shape, the weight of a roof deck may cause the roof to collapse.

What should you look for before installing a roof deck?

The condition of your roof tiles

Your tiles should be of a uniform color, without cracks, breaks, or missing pieces. Worn tiles are faded and discolored, and may not retain their ability to repel water in the most worn areas. 

Another sign of worn tiles is accumulation of asphalt granules in the rain gutters, which occurs as the asphalt tiles gradually wear from sun, wind, and rain.

Pooled water

Water will accumulate at the lowest point of any surface. If water puddles are present on your roof, it is a sign that the structural integrity of your roof has been compromised in those areas, creating low spots on your roof. 

Pooled water will further weaken the area and eventually make its way into your home. In addition, these low points on your roof will create stability issues if you attempt to build a roof top deck without addressing the problem.


Leaks can be deceptive, because while some leaks may seem minor and sporadic, occurring only during heavy storms, water can travel a circuitous path and accumulate inside your ceilings and walls, which can cause major structural damage over time. Look for water stains or mold on ceiling tiles and upper portions of walls, especially in attics or upper rooms in the home, even if you haven't seen any water leaks.

If you are experiencing a roof leak, no matter how small or inconsistent, you should get a professional roofer to determine the source of the leak and examine the roof for any structural damage. This is especially true if you intend to install a rooftop deck.

If you need to have roofing work done before having a deck installed, you should check with the roofer to determine if your warranty will be voided by the addition of a deck. Your roofing contractor may be able to provide additional services such as the addition of a waterproof membrane that will cover the roof and offer further protection before the deck is installed.

If all of the cumulative expenses seem to make deck installation cost-prohibitive, you can always compromise and use interlocking playground tiles to cover a portion of your roof. They are easy to place and remove, and are sold in a wide variety of styles and colors. Add a few pieces of outdoor furnishings and you can still have your rooftop sanctuary. Of course, you still need to check and repair your roof.
