Before buying: measure the real slab/deck, verify permit and wind/snow requirements locally, and confirm current model specifications with the manufacturer. PergolaSpec has not physically tested every product listed.
The roof is a water-management system
When closed, louvers typically direct water toward perimeter gutters and then into posts or downspouts. Ask where the outlets terminate, whether the gutter is serviceable, how wind-driven rain is handled and which conditions require opening the blades.
Manual vs motorized louvers
| Manual | Motorized | |
|---|---|---|
| Setup | No branch circuit | Power, controller and weather protection |
| Failure mode | Crank/gear hardware | Motor, sensor, remote and control board |
| Best fit | Occasional adjustment | Frequent daily use |
| Must verify | Reach and gear access | Manual override and replacement support |
Maintenance questions
- Can leaves be removed from gutters without dismantling blades?
- Are seals and motors replaceable by model number?
- What cleaning products are excluded by the finish warranty?
- How should louvers be positioned for snow, freeze or high wind?
For powered systems, use the motorized pergola checklist. For structural layout, start with the size planner.
