Roof Replacement and Installation on the Oregon Coast

What a full roof replacement actually includes

A real replacement is more than swapping the shingles. It is rebuilding the whole weather barrier from the deck up, and every layer matters more on a wet, windy coast than it does almost anywhere else. Here is what goes into the job when we do it:

• Tear-off to the deck. We strip the old roof all the way down to the wood sheathing so nothing old gets buried under the new roof.
• Decking inspection. With the deck exposed, we can actually see it. We check for soft spots, rot, and delamination and show you anything that needs to be replaced before we cover it back up.
• Underlayment. A modern water-resistant underlayment goes down over the deck as a second line of defense, with ice-and-water membrane in the spots that take the most punishment.
• Flashing. Valleys, chimneys, sidewalls, and roof-to-wall transitions get new flashing. This is where most coastal leaks actually start, so we do not reuse tired old metal.
• Ventilation. Intake and exhaust venting that lets your attic breathe, which is what keeps a roof dry from the underside and protects the new investment.
• The new roof system. Your chosen material installed to the manufacturer's specification with coastal-grade fastening.
• Cleanup and a magnet sweep. We haul off the debris and run rolling magnets across your yard and driveway to pick up stray nails so your family and pets stay safe.

When replacement beats repair

A good repair can buy a sound roof several more years, and we will tell you honestly when that is the smarter spend. But there is a point where patching keeps costing money and stops solving the problem. These are the signs it is usually time for a full replacement:

• Multiple layers already on the roof. If a previous roof was installed over the old one, you are at the end of the road. There is no roofing over a layover again.
• Widespread granule loss. When the protective granules are washing into your gutters across the whole roof, the shingles are wearing out everywhere, not just in one spot.
• Repeated leaks. If you have chased the same leak more than once, or new leaks keep showing up in new places, the system is failing rather than a single component.
• An end-of-life roof. Most asphalt roofs on the coast simply age out, and salt air and constant moisture can shorten that life compared to a dry inland climate.
• Sagging or visible deck movement, which can point to moisture damage underneath that a surface repair will never fix.

Not sure which side of the line you are on? Our repair-vs-replace guide walks through the honest decision framework, and a free inspection gives you a real answer for your roof rather than a guess.

Materials we install and who each one suits

There is no single best roof for every coastal home. The right choice depends on your roof's pitch, your budget, the look you want, and how exposed your home is to wind and salt. We install three main systems and will walk you through the trade-offs for your specific house.

• Architectural and designer asphalt shingle. Owens Corning TruDefinition(R) Duration(R) architectural shingles and Berkshire(R) Collection designer shingles give you a proven, good-looking, cost-effective roof. Owens Corning architectural shingles are also available with algae-resistant options for the damp, moss-prone coast. A strong fit for most sloped coastal and valley homes that want value and curb appeal.
• Standing-seam metal. 26 and 24-gauge standing-seam metal sheds wind-driven rain, resists moss, and lasts a long time in a marine climate. A great choice for homeowners who want maximum longevity and a clean, modern look.
• PVC and TPO membrane. A welded single-ply membrane with stainless components is built for low-slope and flat sections where shingles will not work, and it holds up well against standing water and coastal exposure. We install both PVC and TPO and will walk you through the honest trade-offs: PVC's welded seams and salt and chemical resistance are a genuine coastal strength, while TPO is a valid, often lower-cost option we also install.

One honest note: we are an experienced installer of these materials, not a manufacturer-certified dealer. What that means for you is straightforward. The manufacturer's material warranty covers the product itself on the manufacturer's terms, and our own written 10-year workmanship warranty covers how we install it. We keep those two things separate and explain both before you sign.

Why we tear off instead of roofing over on the coast

Roofing over an existing roof is faster and cheaper up front, and on a dry inland house it is sometimes a reasonable call. On the Oregon coast, it is usually the wrong one, and here is why we tear off down to the deck instead.

1. It traps moisture. A new layer over an old one seals damp, salt-laden material against your deck. In our marine climate, that is exactly how slow, hidden rot gets started.
2. It hides problems. If we cannot see the deck, we cannot catch soft wood, failing flashing, or old leak damage. A layover buries those issues instead of fixing them.
3. Fasteners need real wood. Wind-rated fastening only works if the nails bite into sound sheathing. Driving them through a spongy old roof gives you a roof that is more likely to lift in a strong coastal gust.
4. It shortens the life of the new roof. Extra heat, trapped moisture, and an uneven surface all wear out the new layer faster, which costs you more in the long run.

Our coastal-grade approach

Salt air is hard on metal, and wind-driven rain finds any weak point in the details. A roof that would last for decades in a dry valley can corrode and leak years early on the coast if it is detailed like an inland job. We build every coastal roof for the conditions it actually lives in:

• Stainless fasteners and flashing in the areas where corrosion does the most damage, so salt air does not eat the parts holding your roof down.
• Corrosion-resistant detailing at valleys, penetrations, and roof-to-wall transitions, the places coastal leaks actually begin.
• Wind-rated fastening installed to spec so the roof stands up to the strong gusts that coastal homes see in winter storms.
• Ventilation done right, so the attic dries out instead of holding the moisture that rots decking from below.

This is the part you cannot see from the curb, and it is the part that decides whether your new roof actually goes the distance out here. It is also the reason a local crew that builds for the coast every day is worth more than an out-of-town truck that does not.

Our roof replacement process, step by step

1. Free inspection. We come out, get on the roof, and assess the whole system. No charge and no pressure.
2. Itemized written estimate. You get a clear, line-by-line estimate that spells out the materials, the work, and the scope, so there are no surprises.
3. Material selection. We help you choose the system and color that fit your home, your exposure, and your budget.
4. Permit. We pull the proper permit so the work is inspected to code (more on that below).
5. Tear-off and decking inspection. We strip the old roof, inspect the exposed deck, and show you anything that needs replacing before we move on.
6. Installation. Underlayment, flashing, ventilation, and your new roof system go on, all with coastal-grade detailing and fastening.
7. Cleanup and magnet sweep. We haul off the old roof and sweep the property for nails.
8. Final walkthrough. We walk the finished job with you, answer your questions, and hand over your written 10-year workmanship warranty in writing.

Permits: we pull them so the work is inspected to code

A roof replacement generally requires a building permit, and that is a good thing for you. It means an independent county inspector verifies the work meets code. We handle the permit so you do not have to chase paperwork, and we work with the local permit desks across the area, including Lane, Douglas, Coos, and Lincoln counties depending on where your home is.

If a contractor suggests skipping the permit to save a little money, treat it as a red flag. Permitted, inspected work protects your home, your insurance, and your resale value. Our Oregon roofing permits guide explains how the process works and what to expect.

What drives the price of a new roof

Every roof is different, so an honest estimate has to be based on your actual house, not a one-size-fits-all number. These are the main factors that move the price of a roof replacement up or down:

• Size. More square footage means more material and more labor.
• Pitch. A steeper roof is harder and slower to work on safely, which adds cost.
• Layers. Tearing off multiple existing layers takes more time and disposal.
• Decking. If we find rotted or soft decking once the old roof is off, replacing it adds to the job. We show you what we find before we proceed.
• Material. Asphalt shingle, standing-seam metal, and PVC or TPO membrane each carry different material and labor costs.
• Coastal detailing. Stainless fasteners and corrosion-resistant flashing cost more than standard parts, and they are worth it out here.

Our coastal Oregon roof cost guide breaks down each of these drivers in plain language so you understand what you are paying for. We offer flexible financing through Acorn Finance to make a new roof easier to budget. You can check your rate in minutes without affecting your credit score, on our Financing page.
