Manning Design + Construction is an industry leader in the design and installation of green roofs (ecoroofs), rooftop patios and decks, rooftop gardens and rooftop solar arrays in the Portland, Oregon metro region and beyond. We work with customers to maximize the square footage of their available rooftop capacity to accommodate a variety of uses. From rooftop event spaces, rooftop decks and rooftop patios or rooftop flower, native plant, and vegetable gardens we help our Portland clientele get the most out of their valuable rooftop spaces.

With our 40 plus years of construction and contracting experience in the Portland, Oregon region we can help you navigate the complexities of accessibility codes, safety requirements, and structural load capacity regulations. We engineer and upgrade existing rooftop structures to handle increased loads and to perform under seismic conditions predicted for our region. We can manage individual project needs from conception and design to construction and maintenance.

With property costs at a premium, we help our clients utilize their rooftop to improve, transform and increase their residential and/or commercial environment while decreasing energy costs and mitigating stormwater runoff. We help our clients bring older buildings into a future that is challenged by climate change and its effect on our urban environment.

If you have a rooftop patio or rooftop deck, rooftop garden, rooftop solar or other rooftop development project or just want to see how you can better utilize your rooftop space in the Portland metro area (including Multnomah, Clackamas and Washington Counties and beyond), contact us to discover how we can help you save time and money.
