How does a lattice patio cover handle rain?

Rain passes through it. A lattice cover is an open roof of spaced aluminum tubes that gives filtered shade and airflow. It does not block rain and has no built-in gutter. That suits a pool deck or a seating area where occasional rain is not a concern. It is not ideal for an outdoor kitchen where rain protection matters.

How does a solid patio cover handle rain?

A solid cover is watertight. Rain runs off the surface into a built-in gutter system that directs the water away from the patio. That makes it a good fit for outdoor dining areas and kitchens.

How does an insulated patio cover handle rain?

It blocks rain just like a solid cover. The panels are 4 feet wide with a 3-inch foam core. The wiring for fans and lights runs inside the panel, with no exposed conduit.

How is a patio cover checked for wind?

Through the building permit. Clark County and the cities of Las Vegas, Henderson and North Las Vegas all require a building permit for a patio cover. The permit process includes a plan review and a final inspection to verify that the structure meets building codes for wind load, attachment and structural integrity.

An attached cover uses the house as one side of its support. A freestanding cover absorbs all wind forces through its own posts and footings rather than sharing the load with the house.

City Seamless Patio Covers handles the entire permit process, from application through final inspection. Our permit guide explains the steps.

Which patio cover should I choose for a dry patio?

For a dry patio, choose solid or insulated. For filtered light and airflow over a pool deck, choose lattice. A combination cover mixes solid and lattice sections under one structure.
