The Best Decking Materials for Your Rooftop Deck Project

Written by on

When you are building a rooftop deck, your most important considerations might be strength and longevity. And, of course, a beautiful finished deck! Hardwood decking materials such as Ipe wood, Machiche wood decking, Garapa wood, and other hardwoods perform in all three categories. While there are plenty of synthetic decking materials to choose from, they don’t always stand up to the onslaught of UV rays, weather conditions and other elements that a roof deck is exposed to every day. Hardwood decking performs in rooftop deck areas naturally and beautifully.

Why Hardwood Decking over Composite  Decking?

Composite decking is a mixture of sawdust and plastic that is pressurized and extruded into decking boards. Composite decking materials are available in many colors and often look very nice at first. However, over a short period of time on the punishing conditions of a rooftop deck, composites and other synthetic decking materials tend to 'ugly out' rather quickly.  And there's not a whole lot you can do to change their appearance. Composite decking cannot be sanded or refinished. It is what it is. 

On the other hand, with high performance hardwood decking materials, you have options. Hardwood rooftop decking can stay beautiful for as long as you wish. if you want hardwood decking to look like new, you can oil it up as needed. Or, you can allow it top silver out naturally, and still look beautiful.   

With naturally high density and amazing strength, exotic hardwood decking materials boast an inherently high resistance to rot, mold, and even insect damage. This means no worries about regular repairs or high maintenance to maintain the deck and its good looks. Unlike composite and synthetic decking, the performance of high density hardwood decking is "grown" in with excellent resistance to the elements, naturally.  

Architects and home designers like the deck design flexibility of  wood decking. Natural wood can be used for the deck surface, the railings, planters, overhangs, and even built-in furniture. Mataverde hardwood decking can be used in long lengths, patterns, and architectural features that synthetics can't match.

A Low Maintenance Rooftop Decking Option

Wanting the “just installed" wood look to last? Since rooftop decks are up high, with very little shade, there is a higher amount of UV exposure bearing down on it all day, every day.  Protect your deck surface from the elements with an initial coat of Penofin Oil Based UV Protectant, or a similar product. This oil finish is designed to block the UV rays and minimize the damage from harmful UV exposure.  It can be easily reapplied as needed. 

Alternatively, if you prefer the silver-gray patina as many do, all hardwoods can be allowed to “silver out” in the sun without degrading their strength or durability. Simply do not reapply the UV protectant after installation and allow the decking to weather gracefully on its own.

All decking materials need to be cleaned regularly to maintain their good looks.

  • With composite decking materials on a rooftop deck, your only option is to clean your deck as needed. Composite decking cannot be refinished or sanded.  When composite decking starts to fade or degrade, your options are limited to covering it up or replacing it at the end of its lifecycle.
  • When using softwoods and pressure treated wood decking, the UV rays will gray the surface but will also damage it unless annually stained, painted or sealed. Hardwoods will retain their amazing strength after turning silver, without applying any additional product. And without the cupping, checking, or splitting that plagues softer wood decking materials as they weather.
  • All hardwood decking needs is a quick cleaning when desired. This makes the” grayed out” hardwood deck the lowest maintenance option, an option not found in softwood or synthetic wood decking material.



An Easier, More Durable Rooftop Deck Installation

When combined with the Mataverde Eurotec Rooftop Deck System, any of these decking materials are easier and faster to install. The Eurotec deck system uses adjustable rooftop deck pedestals to follow roof slope or height changes easily. This ensures adequate drainage under your deck and the spacing allows your deck boards to "breathe". Since the Eurotec system uses aluminum rails instead of wood, it prevents potential threats to your rooftop deck underneath the surface like water damage, warping, and rot.

Machiche’s light chocolaty brown to dark reddish-brown shades are a popular look for a rooftop deck.
