Portland, ME's Trusted Patio Cover Contractor Since 1978
Patio Cover Installation in Portland, ME
An uncovered patio in Portland is only usable on perfect days. A professionally installed Sunspace patio cover protects your outdoor space from rain, UV rays, and heat, turning a weather-dependent area into a reliable, year-round extension of your home.
The Problem with an Uncovered Patio
Rain, Heat, and UV End Your Outdoor Season Early
5
months. Portland averages over 100 frost days per year and consistent summer rain events. Without overhead protection, your patio furniture, flooring, and outdoor time take the full impact of Maine’s climate every season.
An exposed backyard patio in Southern Maine loses usability fast. Rain drives you inside, afternoon sun overheats the space, and UV rays fade furniture and damage skin. The transition from a perfect morning to an afternoon downpour can happen in under an hour.
A custom aluminum patio cover installation changes what your outdoor space can do. It extends your usable season, protects your investment in outdoor furnishings, and creates a covered retreat that performs in every condition Maine delivers.
Full Rain Protection
A properly installed patio cover keeps your outdoor space completely dry and usable through Portland's spring, summer, and fall rain events.
UV Filtering
Every Sunspace patio cover system filters or blocks harmful UV rays, protecting your furniture, your flooring, and your family from cumulative sun damage.
Heat Control
Insulated panel systems regulate the temperature beneath the cover, keeping your patio noticeably cooler on peak summer afternoons.
Natural Light Options
Acrylic and Hybrid systems maintain up to 90% light transmission, so your covered patio stays bright and open even when fully sheltered from the elements.
Zero Maintenance
Every Sunspace cover system uses aluminum frames and engineered panels that never need painting, sealing, or staining. Clean when needed, leave the rest alone.
Added Home Value
A covered outdoor patio is one of the most impactful investments a Portland homeowner can make, extending usable square footage and improving resale appeal.

Common Questions
Patio Cover Installation FAQs
Everything Portland homeowners ask before scheduling their first consultation.
The Solid Insulated cover uses a high-density foam core with aluminum or OSB panels to block all sunlight and provide maximum insulation at R-12, R-16, or R-24. The Acrylic cover uses UV-stable acrylic panels that maintain up to 90% light transmission for 30 years, keeping your patio bright while blocking rain and UV rays. The Hybrid cover combines both panel types in any configuration, giving you full control over where you want shade and insulation versus where you want natural light.
Panel thickness is chosen based on three factors: your roof projection length, your local snow load requirement, and your desired R-value for thermal comfort. Our design consultants assess all three during your free on-site visit and recommend the right thickness for your specific patio layout and intended use.
Yes. All three Sunspace patio cover systems are structurally designed to support ceiling fans, lighting fixtures, and hanging plants without requiring additional structural modification. Your consultant can include electrical access points in the design specification if needed.
Yes. All three systems can be installed over an existing deck or patio surface without requiring a new foundation or structural rebuild. Our consultants assess your existing structure during the free consultation to confirm the right attachment method and anchoring approach for your specific setup.
Acrylic panels filter and soften direct sunlight rather than blocking it entirely. The diffused light that passes through is noticeably more comfortable than direct sun exposure, and the aluminum frame and gutter system allow air to circulate at the perimeter. Homeowners who want maximum heat control typically choose the Hybrid system, placing solid insulated panels on the side that receives the most direct afternoon sun.
Yes, and many homeowners do. A patio cover over a primary seating area pairs naturally with a louvered pergola installation in an adjacent open zone, or with a screen room installation alongside the covered patio to create a fully protected outdoor space. We can design and manage any combination as a single project.
Absolutely. Acrylic privacy wall panels can be added along one or more sides of any patio cover installation, blocking neighbor sightlines and coastal wind while the cover handles overhead protection. This combination creates a genuinely private, sheltered outdoor room without requiring a full enclosed structure.
