With aluminum, you can get slatted covers (pergolas) in the $10-20/SF range if not too fancy or fully hurricane rated, another 15-25% typically if hurricane rated. Solid covers start around $20/SF for prefab covers, on up to $40 or so for ones rates for hurricane rating or heavy snow loads - and of course on up from there if fancy columns or such.

Installation another $2-10/SF typically depending on whether permanent foundation piers/footing are needed or it can just be embedded in the ground aways or put on footer blocks, and on how the interface to the house is done to provide stability without introducing leak issues. The greatest difficulty is in snow/ice areas where adding a pergola or patio/porch roof to the existing one can cause ice damming as the snow/water comes off the warmer roof onto the cold patio cover and freezes, causing water backups. Or if fastened to the fascia board or rafter tails, avoiding issues with water/ice damage to them.

Here are links to a couple of related previous questions that might help too -

Vendor categories for this vary by the vendor's individual range of products they offer - prefabs from various companies and box stores and such of course, some of which (especially pergolas which have little snow load weight) are small enough for DIY. Contractors include Awnings, Roofing, Deck and Porch contractors as well of course as Remodel - General Contractors - as well as Handymen for smaller/simpler ones of course, especially if not actually tying into the existing roof.

At this time, we don't track going rates for various projects because these prices vary widely depending on market factors and location. We encouage members to include the cost of their project in their reviews.

When you're looking at a particular company's reviews, you can get an idea of the average cost based on what other members paid. You can also compare those amounts to rates charged by other providers.

We'll be happy to help find top rated providers for your aluminum patio project, but it doesn't look like you have a subscription to the List yet.
