“I was leaning towards Hardie Board to replace my 35+ year old white cedar clapboards. Lucas suggested Hardie Board and explained how it needed a little different installation than conventional siding installation, which I had read about already, so I felt confident they knew what they were doing. I also had an awning and outside shower stall, which they removed and replaced and replaced some steps to my deck that were falling apart, as well as replacing bad trim. The price was right, the crew was friendly and worked diligently and fast. It was an overall great experience.”

“Putting a shout out to Coastal Roofing And Siding and especially to Roberto Carvalho who guided us through the contract, what to expect, the pricing which was very reasonable and the job. We had our vinyl siding replaced, which was a job filled with unexpected complications They were professional, they handled our concerns with consideration and care. They cleaned The job site after every days work. We had a few hiccups at the end, but Roberto took care of them with promptness and respect for our wishes. We would recommend Coastal Roofing And Siding to anyone who needed a professional ,caring, Company that will go the extra mile to make their customers happy”

Why It Matters

Create New Memories in a Comfortable, Safe Space

A great deck turns your backyard into a place you actually want to spend time. But on Cape Cod and South Shore, a deck has to be built to take the weather. Salt air, sun, and moisture break down decks that were not built properly.

From construction to finishing, whether it is a new deck build, deck repair, or a full renovation, every step is carefully planned to create a safe, durable space. We use premium composite and pressure-treated lumber with proper framing, footings, and fasteners that keep your deck solid for years.

What We Do

Decks Services

Custom Deck Design

We design a deck that fits your home, your yard, and how you actually want to use the space.

Composite Decking

Low-maintenance composite decking that resists fading, staining, and rot, perfect for the coastal climate.

Natural Wood Decks

Classic pressure-treated and cedar decks, built with proper structure and sealing to last.

Deck Renovation

Resurface or rebuild your existing deck with new boards, railings, and structure to make it safe and beautiful again.
