Roof Replacement and Installation on the Oregon Coast

What a full roof replacement actually includes

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

• Tear-off to the deck. We strip the old roof down to the wood sheathing so nothing old gets buried under the new one.
• Decking inspection. With the deck exposed, we check for soft spots, rot, and delamination, and show you anything that needs replacing before we cover it back up.
• Underlayment. A modern water-resistant underlayment goes down as a second line of defense, with ice-and-water membrane where the roof takes the most punishment.
• Flashing. Valleys, chimneys, sidewalls, and roof-to-wall transitions get new flashing. This is where most coastal leaks start, so we do not reuse tired old metal.
• Ventilation. Intake and exhaust venting that lets your attic breathe, which keeps the roof dry from the underside.
• The new roof system. Your chosen material installed to the manufacturer's spec with coastal-grade fastening.
• Cleanup and a magnet sweep. We haul off the debris and run rolling magnets over 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 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 granules are washing into your gutters across the whole roof, the shingles are wearing out everywhere, not just one spot.
• Repeated leaks. If you have chased the same leak more than once, or new ones keep showing up, the system is failing, not just a single part.
• An end-of-life roof. Most asphalt roofs simply age out, and salt air and constant moisture shorten that life compared to a dry inland climate.
• Sagging or visible deck movement, which points 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 it, and a free inspection gives you a real answer for your roof, not 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 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 house.

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

One note on coverage: we are a certified Owens Corning Preferred Contractor, and we install membrane and metal systems from other manufacturers as well. Whichever you choose, the manufacturer's material warranty covers the product on their terms, and our own written 25-year workmanship warranty covers how we install it. We keep those 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. Here is why we tear off to the deck instead.

1. It traps moisture. A new layer over an old one seals damp, salt-laden material against your deck, which is exactly how slow, hidden rot gets started here.
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 instead of fixing them.
3. Fasteners need real wood. Wind-rated fastening only works if the nails bite into sound sheathing. Driven through a spongy old roof, they are far 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.

Our coastal-grade approach

Salt air is hard on metal, and wind-driven rain finds any weak point. A roof that would last 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 roof for the conditions it actually lives in:

• Stainless fasteners and flashing 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, where coastal leaks actually begin.
• Wind-rated fastening to spec, so the roof stands up to the strong gusts of a coastal winter.
• 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 goes the distance out here. It is also why a local roofer who builds for the coast every day beats 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. Written estimate. You get a clear written 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 25-year workmanship warranty.

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: an independent county inspector verifies the work meets code. We handle the permit so you are not chasing paperwork, and we work with the local desks across Lane, Douglas, Coos, and Lincoln counties depending on where you are.

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 it works.

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 things that move the price 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 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 in plain language. We offer financing through Acorn Finance, so a new roof does not have to wait. See our Financing page for details.
