Pergolas and shade covers in Fort Collins

Shade over a new or existing deck, from an open pergola to a full roof, sized for the snow and wind your town designs for.

A pergola or roofed cover is what makes a west- or south-facing Fort Collins deck usable on summer afternoons. Homeowners in Fort Collins, Loveland, Windsor and nearby towns can get connected with a contractor who builds shade over new decks or adds it to decks that can carry the extra weight.

What are the options?

  • Open pergola. Beams and rafters that break up the sun; shade cloth or slats add more.
  • Louvered pergola. Aluminum blades that open and close for sun or rain.
  • Solid roof. A shed or gable roof over all or part of the deck, sometimes with ceiling fans and lights.
  • Freestanding shade. A pergola on its own posts and footings next to or over a patio.

Why the deck underneath matters

A roof adds weight that the deck's beams and piers were probably not sized for. Fort Collins requires engineered plans or letters for patio covers or pergolas that bear on top of a deck. Snow drives much of that design: Larimer County's deck handout lists a 40 psf ground snow load at 5,500 feet and below and higher loads above that, while Windsor and Wellington list 30 psf in their adopted design criteria. Wind matters too, with Windsor's table listing a 115 mph design wind speed.

Signs you'd use a cover

  • The deck faces west and sits empty until the sun drops behind the foothills
  • Dark composite boards get too hot for bare feet
  • You want to grill or sit out during spring and fall showers
  • Your furniture fades or cracks in a few seasons

Permits and neighbors

A roof over a deck counts toward setbacks and lot coverage in most zoning codes, and roofed structures go through plan review. In Fort Collins, new lights on the cover should be shielded and downward-directed or dark-sky compliant, matching what the city asks for at deck landings. If your home is a designated landmark or in a historic district, the city's Historic Preservation office reviews exterior changes; it has issued certificates of appropriateness for projects as small as a rear patio.

What affects the price?

  • Size, open vs. louvered vs. roofed
  • Engineering and any added footings or beams
  • Materials: wood, steel or aluminum
  • Electrical for fans, heaters or lights
  • Tying a roof into the house and its gutters

Covers are priced by the contractor after a site visit. We don't quote shade structures.

Common questions

Can I add a pergola to my existing deck?

Possibly. In Fort Collins, a pergola or patio cover that bears on a deck needs engineered plans, and the deck may need added footings or beams.

What snow load does a deck roof have to carry?

It depends on who issues the permit. Larimer County's deck handout uses 40 psf at 5,500 feet and below; Windsor and Wellington list 30 psf.

Do louvered pergolas need a permit?

Most attached or roofed structures do. Ask the building department for your address, since thresholds differ between Fort Collins and the surrounding towns.
