When it comes to home repiping, the layout of your house plays a major role in determining the best approach. Homes with attics and homes with flat roofs require different methods to minimize disruption, maintain efficiency, and ensure a clean finish. Below are some common options.

What Are Your Repiping Options If You Have an Attic?

For houses with attics, we typically run new water lines overhead and drop them inside walls to connect with fixtures. This approach reduces the number of wall openings required.

When the work is complete, we patch and paint, leaving you with a seamless finish.

Homeowners can choose between copper piping and PEX piping depending on their budget and local water chemistry.

What Are Your Repiping Options If You Have a Flat Roof?

Flat roof homes require specialized solutions since attic space is not available. The good news: you don’t have to break up your slab to get a clean repipe. Here are the main methods:

Roof-Top Copper (Hybrid or Full Copper)

• Copper lines are installed along the roof with sealed penetrations.
• UV-protected insulation helps maintain stable water temperatures.
• Inside walls, you can choose PEX drops for a quicker installation or go with full copper for a premium system.

Perimeter Trenching

• For fixtures along exterior walls, we trench outside the slab and run copper lines underground.
• In California, only copper is approved for direct burial, ensuring long-term durability.

Interior Soffit Build-Outs

• Decorative soffits conceal pipes inside the home.
• No roof penetrations are needed, and all piping remains within the home’s thermal envelope for better efficiency.
