Design It Your Way
Deck Materials and Options That Fit Your Style
We offer a variety of decking materials to match your style preferences, maintenance needs, and long-term goals. Treated lumber is a budget-friendly option with a natural appearance, making it ideal for simple platforms or starter decks. Cedar provides a rich, high-end aesthetic with resistance to insects and rot. For a low-maintenance, long-lasting surface, composite decking provides fade resistance and eliminates the need for staining or sealing. Add aluminum, vinyl, or wood railings for safety and style, and consider built-in lighting or custom stairs to complete the look. We also build patio and deck covers to provide year-round comfort and protection. Not sure where to start? Our team will guide you through each decision, ensuring your deck not only looks great but performs beautifully for years to come.

FAQS
Building Your Custom Deck
What decking materials do you offer?
Ultima Roofing & Exteriors offers a full range of decking materials to suit your needs, budget, and aesthetic preferences. We commonly install treated lumber, cedar, and composite decking. Treated lumber is a great option for basic platforms and starter decks—it’s affordable, durable, and easy to work with. Cedar offers a more premium look with natural resistance to moisture, insects, and decay. If you prefer a long-lasting, low-maintenance solution, composite decking is an ideal choice. It resists fading, warping, and splintering and requires no staining or sealing. In addition to deck surfaces, we offer railing options, including aluminum, vinyl, and wood to enhance safety and style. We also build custom deck covers and patio roofs to provide year-round comfort and protection. If you're unsure which combination works best, our team will walk you through the options and help design a deck system that fits your space, use case, and budget.
How long does it take to build a deck?
Most deck construction projects at Ultima Roofing & Exteriors are completed within two to three weeks after the estimate is approved and materials have been delivered. The exact timeline can vary depending on factors such as the deck’s size, complexity, material selection, weather conditions, and whether permits are required. Our team works efficiently but never compromises on quality—we ensure each build is structurally sound, visually cohesive, and fully code-compliant. Once we finalize your design and timeline, we’ll keep you informed every step of the way so you know what to expect and when. From site preparation to framing, decking, railing, and final cleanup, we manage the entire process to minimize disruption to your home. Our crews are respectful, efficient, and committed to leaving your property clean and your project completed to the highest standards. We also provide a final walkthrough to ensure every detail meets your expectations.
Can you add a patio cover or railing to an existing deck?
Yes—Ultima Roofing & Exteriors can often add features like railings, staircases, or patio covers to an existing deck, provided the structure is sound and meets current building codes. If your existing deck is in good condition, we’ll evaluate how best to integrate new components, such as aluminum or vinyl railings, post-mounted lights, or a covered roof extension, for added comfort and weather protection. If your deck has minor wear, we may recommend reinforcing or upgrading it before installation to ensure safety and longevity. Our design team will assess your space and create a cohesive plan that matches your home’s exterior and your goals for the space. Whether you're looking to increase safety for children and pets, add privacy, or expand your deck’s usability year-round, we’ll help you find the right solutions. If your existing deck isn’t structurally sound, we’ll explain your options for partial rebuilds or full replacements as needed.
Do you repair old or unsafe decks?
Absolutely. At Ultima, we frequently assess and repair older decks that have become unsafe due to age, weather exposure, or poor installation. Common problems we address include rotted posts, unstable railings, sagging boards, and failing stair structures. Our team will begin with a thorough inspection to evaluate the current condition of your deck and identify safety hazards or structural weaknesses. In many cases, we can reinforce or replace specific elements without the need for a complete rebuild. However, if the damage is extensive or the materials have deteriorated significantly, we may recommend replacing the deck for both safety and value. We’ll provide a transparent estimate and walk you through your options so you can make the right choice for your home. Our goal is to restore confidence in your outdoor space, whether through targeted repairs or a fully updated structure designed to last.
Are your decks covered by a warranty?
Yes—all deck projects completed by Ultima Roofing & Exteriors are backed by our 10-year in-house workmanship warranty. This means we stand behind our construction methods and will address any issues related to labor or installation errors for a full decade. It’s part of our commitment to delivering long-term value and peace of mind. In addition to our workmanship warranty, many of the materials we use—such as composite decking and aluminum railings—also come with manufacturer warranties. These often range from 25 years to limited lifetime coverage, depending on the product selected. We’ll explain all warranty details before construction begins so you fully understand what’s covered and for how long. Should any issue arise, we’re just a phone call away. With Ultima, you’re not only getting a high-quality deck—you’re gaining a reliable partner who supports your investment long after the build is complete.
