Attaching Pergola to an Existing Roof

Outdoor living is a great way to enjoy a backyard. Throughout the southwest United States, there is good weather all year long, encouraging people to make the most of their backyard. This includes being able to grill, entertain and generally relax outdoors. Providing shade for your back patio is also a necessity because of the extreme heat in many instances.

As Spring turns to Summer and the nights become longer, homeowners are looking for a solution to shield against the never-ending sun. That is, if you’re lucky. In some areas, sun is an afterthought.

If your last frost is in mid-January or February, listen up! You likely live in one of the hottest zones in the United States. From Southern California, Arizona, New Mexico, Southern Nevada and Texas, the pergola or “projecting eve” is gaining in popularity.

First used in historical gardens throughout the 17th and 18th centuries, this structure provides shade to millions.

Two frequently asked questions come to mind: will it be free standing or attached to an existing house?

Well, if you plan on building in the middle of your backyard – the answer is simple: free standing.

A large portion of our society deems the back patio (yes, the one directly behind your house) as a suitable gathering place. Which usually results in a 3-sided structure.

What will the fourth side attach to? You guessed it... your house!

Here is where the fun begins.

Attaching pergola to an existing roof

Thousands of houses in the continental United States (oh, and Alaska and Hawaii) attach their pergolas straight to the roof or fascia board. The latter being a big no, no.

Of course, a pergola does not require as strong of a lateral load as, let’s say, a solid patio roof. However, why would you want a structure constantly pulling at the end of your rafters?

Even if you didn’t take the “less than ideal route” of attaching directly to fascia, attaching to the wall plate of one’s house is much more secure (in the event of high winds) and increases one’s options.

This post would not be complete without showing you how the SkyLift roof riser bracket solves this issue. The chance of timber rotting against the house, blown off by high winds or comprising your existing rafters, just dropped significantly. All because a product made of heavy duty cold rolled steel is available to make your wildest dreams come true... well, almost. See the SkyLift Roof Riser in action!
