Almost every decision here comes back to that one question, so it is worth answering before anything else.
An open frame of beams overhead. It cuts the afternoon sun and gives the deck a sense of enclosure while keeping it open to the sky. It does not keep rain off, and it is not meant to.
A solid roof over the deck. It keeps rain off you and off your furniture, which is what lets you use the deck in the months when it is actually raining.
Around here a lot of people ask about a pergola when what they really want is the rain handled. Being clear about which one you are after saves a conversation later, because they are different structures at different prices.
The obvious part is that you stay dry. The less obvious part is that your outdoor furniture stays dry too, so it lasts longer and you stop hauling cushions inside every time the forecast turns.
A covered deck will block some natural light entering the room behind it. The impact depends on your home's orientation and the size of the cover. We recommend evaluating this before you build, and we will look at lighting and window placement with you during your on-site consultation.
Water has to go somewhere, so a roof needs gutters and a plan for where the runoff ends up. Sending it to a spot that already puddles just moves the problem, and with the rain we get that shows up fast.
A roof is heavy and it catches wind. An existing deck was built to hold people and furniture rather than a structure, so the frame and footings often need work before a cover can go on it.
That does not mean it cannot be done. It means the honest answer comes after we have looked underneath. We check the footings, the posts, and how the deck ties to the house, then tell you what the cover would actually involve.
If the deck is due for new boards anyway, doing both at once saves paying for access twice. See Deck Resurfacing.
Oregon's residential code generally exempts a cover of 200 square feet or less from a building permit, provided it is attached to an exterior wall of the house, averages no more than about 12 feet to the roof, and stays at least 3 feet back from any property line. Go over any one of those and a permit is normally required.
Zoning is a separate question and applies either way. Setbacks, how much of the lot you can build on, and any overlay on your property do not go away just because a cover happens to be permit-exempt, and cities differ in the details. We check what applies to your lot before anything gets designed, and we file the paperwork.
Sometimes, and sometimes the deck needs work first. It depends on whether the footings and framing can carry the extra weight, which was probably not what they were built for. We look underneath before answering.
If the goal is using the deck when it is raining, you want a roof. A pergola is for shade, and shade is not usually what limits deck use here. If you want both, a roof over part of the deck with an open section next to it is a common way to go.
Often, though not always. Oregon's code generally lets a cover of 200 square feet or less go without a building permit when it is attached to the house, stays under about 12 feet of average roof height, and sits at least 3 feet from any property line. Larger or detached covers normally need one, and zoning setbacks apply either way.
Lighting, yes, and it is much easier to run while the structure is being built. A fan usually works too under a solid roof, as long as the framing is built to carry it and the fixture is rated for outdoor use — both are worth deciding before the roof goes on rather than after. We can talk through what fits when we come out.
Tell us what you have in mind. We will come out, look at your space, and give you an honest, clear estimate. There is no charge for the visit and no pressure to book.
