A professionally built deck creates the perfect space to relax, entertain, and enjoy the outdoors while adding beauty, functionality, and value to your property. Whether you’re envisioning a small backyard retreat, a large custom outdoor living area, or a commercial deck designed for customers, guests, or employees, Mandette Roofing Plus provides expert residential and commercial deck construction services built to enhance both appearance and long-term performance.
Our team specializes in designing and building custom decks tailored to the unique needs of homeowners, businesses, property managers, restaurants, multi-family properties, and commercial facilities. From simple platform decks to expansive multi-level structures with stairs, railings, accessibility features, and integrated amenities, we work closely with our clients to create outdoor spaces that are both attractive and functional.
For residential properties, a well-designed deck expands your living space and creates the perfect setting for family gatherings, outdoor dining, entertaining, and everyday enjoyment. For commercial properties, decks can enhance customer experiences, improve outdoor seating areas, create gathering spaces, and add value to restaurants, apartment communities, hotels, office buildings, and retail facilities.
Many property owners choose to include deck construction as part of a larger exterior improvement project. New decks pair beautifully with roofing, siding, gutter, window, and exterior renovation services, helping create a cohesive and attractive appearance for the entire property. A professionally built deck not only increases usable outdoor space but can also improve property value and overall curb appeal.
In some situations, decks may require replacement due to storm damage, fallen trees, or other insurance-related events. When applicable, Mandette Roofing Plus can assist homeowners and commercial property owners through the insurance claims process by documenting damage, providing detailed inspections, and communicating with insurance adjusters as needed. Our goal is to simplify the process and help restore your property as efficiently as possible.
At Mandette Roofing Plus, we believe outdoor spaces should be as inviting and functional as the buildings they serve. Our commitment to quality workmanship, professional service, and customer satisfaction has made us a trusted choice for residential and commercial exterior improvement projects throughout Maine, New Hampshire, and Massachusetts.

I recently had a complete roof replacement done by Mandette Roofing Plus, and the experience was outstanding. They removed three layers of old shingles, installed a full layer of new plywood, and completed the entire job in just two days. Their efficiency and professionalism truly impressed me.
