Patio Covers · Carlsborg, Washington

Patio covers in Carlsborg, WA.

Patio covers in Carlsborg add a new roof-water source. Before choosing the easiest downspout connection, have the provider identify whether the proposed receiving pipe is storm drainage or the sanitary side sewer.

A cover gutter should not be connected on the assumption that every underground pipe carries rainwater. Use the actual drainage and sewer records, then ask the responsible designer and County to establish an appropriate roof-water arrangement.

Patio cover installation

Keep patio-roof water separate from the sanitary sewer.

Show the cover roof, gutter and intended receiving route on the site sketch. Keep an unidentified pipe marked as unresolved until the provider establishes its function and the proposed connection is reviewed. Price any needed drainage work separately from the acrylic roof so the starting cover range is not mistaken for a complete site solution.

Identify the receiving system.

Ask the responsible provider to establish what an existing pipe serves using reliable records and any needed assessment.

Draw the new water route.

Include the added roof area, gutter outlet and receiving location with the cover proposal.

Resolve the scope before ordering.

Have the designer and County address any drainage change, and keep that work in the final written price.

Ask about the cover and its roof-water proposal together.

Confirm building and drainage review for the actual site with County DCD and Public Works. The selected size does not approve the receiving connection.

The initial acrylic-cover range is not a drainage design or connection authorization.
