Where do I install the patio roof riser hardware?

To help you understand, visualize your existing house rafters only being 6” long overhanging past your existing exterior wall. That is where the PRR Hardware is mounted.

What if my rafters are not evenly spaced to match the patio that I’m covering?

You do not have to install the PRR only on a rafter tail. You can install 4x8 DF solid blocking flat between the rafters. Predrill both rafters then install blocking flat using (6) 5”Ledgerloc lags 2” O.C. trough rafters into both ends of your 4x8 flat blocking.

What kind of roofing materials can the waterproof PPR hardware be installed on? Composition shingles - three tab - architectural & heavy dimensional. Metal roofing - vertical panel and standing seam.

Will I need to cut into my roof? 

No! There is no cutting into your roof with Patio Roof Risers!

How many Patio Roof Risers will I need?

We recommend 4 foot on center (allowing for a 2 foot overhang on the ends) Example: a 12 foot patio roof would need 3 Patio Roof Risers.

How far do I overhang the roof above the PRR hardware?

Your new patio roof should be cantilevered at least 12” beyond the PRR post & beam above the existing building envelope.


Do you have the engineering?

Yes we having the engineering for the Patio Roof Risers and our structural hardware for Washington, Oregon, and California (located at the top of all pages in the navigation bar). We recommend for customers in all other states to take the Washington, Oregon and California engineering to their local engineer for a stamp of approval.

Do I need to be a professional to install?

No! Patio Roof Risers are designed to keep it simple!

I am going to use rough sawn wood, will these work with it?

Yes! Patio Roof Risers will work with rough sawn wood. Although the standard hardware (bolts and lags) aren't big enough for rough sawn, but we can accommodate for it! Just let us know and we'll get you the right hardware.
