Can You Build a Deck on an Existing Patio or Rooftop?

Yes, you can potentially build a deck on an existing patio or rooftop, but there are a wide range of important factors that must be taken into consideration in the process, and hiring professionals is highly encouraged. The structural integrity of your home and deck are paramount, which makes having the expertise of an experienced Westmoreland County, PA, deck construction pro backing you up invaluable.

A Floating Deck on an Existing Structure

If you have a deck built on an existing patio or flat roof, it’s what’s often called a floating deck. Floating decks are designed to sit on top of existing structures without being directly secured to them. This ensures greater design flexibility and is a good option for incorporating the deck you’ve already got – rather than scrapping it altogether.

Structural Integrity Is Paramount

When retrofitting a deck to your home, prioritizing structural integrity is key. For example, a rooftop deck will put a considerable amount of weight on your roof, and you’ll need to ensure that it is up to the task of supporting that weight. A savvy deck construction professional has the skill, experience, and knowledge to accurately assess your roof’s load-bearing capacity and to make well-informed decisions throughout the building process.

Drainage and Water Management

When it comes to decks – whether built over existing patios or added to rooftops – the matter of water drainage must be considered. Without proper drainage, water can pool and lead to problems in your yard or leaks in your roof – both of which can cause costly and potentially dangerous structural damage.

Building Permits

Building a deck in Westmoreland County generally requires a permit, and you shouldn’t proceed without taking the necessary legal steps. Generally, any deck that is more than 30 inches off the ground or that has a roof requires a permit, and hiring a dedicated deck construction pro helps to ensure that your project will go off without a hitch.

Safety

If you’re considering adding a deck to your home, you undoubtedly are looking forward to enjoying the outdoor space with your loved ones, and this requires a focus on safety.

Factors like the following should be of primary concern:

A deck can be a great addition to your home and putting effort into safety up-front helps to ensure that you and your loved ones will continue to enjoy it far into the future.
