Wind exposure and fastening

Why wind damage on a Washougal roof is a whole-roof question

A shingle that blows off is the obvious problem. The less obvious one is why it came loose. Asphalt shingles hold down through two things working together: nails driven in the right zone of each shingle, and a factory sealant strip that bonds each course to the one below it once the sun warms the roof. If either is weak, wind can get under a shingle’s edge and peel it back. A single torn tab may be bad luck. A pattern of loose tabs across one slope usually points to aging sealant, nails placed too high, or both.

That pattern is what turns a repair conversation into a replacement conversation. Replacing a handful of shingles on a roof where the surrounding courses have also stopped sealing simply moves the next failure a few feet over. On the other hand, a roof that lost a few shingles at one exposed corner, while the rest of the field is still bonded and flexible, is often a good candidate for a targeted repair. A careful inspector lifts a few tabs gently in different areas to see whether the seal strips are still holding, instead of judging by what is missing.

The edges deserve the same attention. Wind loads are highest at eaves, rakes, hips, and ridges, so those are where a roof is built most deliberately: drip edge fastened along the perimeter, starter shingles with their own sealant at the first course and up the rakes, and hip and ridge caps that are made for the purpose rather than cut from field shingles. On older roofs, missing starter strips and cut-tab ridge caps are common reasons a roof seems to lose pieces every winter.

Ventilation belongs in the same assessment. A poorly vented attic can age shingles faster, and a ridge vent product has to be installed to suit the roof and the manufacturer’s instructions so it stays in place. When the roof is replaced, the plan should treat fastening, edges, and ventilation as one design rather than as afterthoughts.

What to check after a Washougal windstorm

From the ground, look for missing tabs, bare strips, or shingle pieces in the yard
Look along the ridge and hips for caps that are lifted, cracked, or gone
Check the rakes (sloped edges) for shingles or drip edge that have pulled loose
Inside the attic, look for new daylight, wet insulation, or stains on the deck
Note which side of the house took the damage — repeated loss on the same slope is worth pointing out
Take dated photos before anything is repaired, especially if you plan to talk with your insurer
Stay off the roof; a loosened roof is especially hazardous when it’s wet or windy

Repair or replace

Repair the wind damage, or replace the roof?

Lost shingles don’t automatically mean a new roof. What matters is whether the shingles that are still in place are holding properly.

Often still a repair

Damage is limited to one exposed area, and the surrounding shingles are still sealed and flexible
A few ridge caps or edge pieces came off, but the field of the roof is in good condition
Replacement shingles can be matched closely enough, and the roof is not near the end of its service life

Points toward replacement

Seal strips have let go across large parts of one or more slopes, not just where pieces are missing
The roof has needed wind repairs more than once, in different places
Shingles are brittle enough that lifting them for a repair would crack the surrounding courses

Moss, stains, or a roof’s age alone don’t settle the question, and remaining life can’t be promised from a photo. An on-site roof inspection is the way to know. See also roof repair vs. replacement.

Scope

A Washougal replacement scope built around wind resistance

Because wind attacks the perimeter and the ridge first, a good scope for a Washougal home should describe those areas specifically, not just the shingle color. Ask the estimate to name the starter product, how drip edge is attached at eaves and rakes, the hip and ridge cap product, and the nailing approach the shingle manufacturer specifies for the product being installed. The rest of the system still matters: full tear-off, decking review once exposed with damaged sheets photographed and reviewed with you, underlayment, flashing, pipe boots, and attic ventilation.

Permits: requirements depend on the city or county with authority over the property — which isn’t always the city in the mailing address — and on the scope, such as whether sheathing or framing is replaced. Ask whether your project needs a permit and who will obtain it before work is scheduled.

Items your written scope should cover

Full tear-off and disposal so fastening starts on a clean, sound deck
Decking review after exposure, at the per-sheet price in the estimate
Starter shingles at eaves and along rakes
Drip edge at all eaves and rakes
Shingle nailing per the manufacturer’s instructions for the chosen product
Hip and ridge caps made for the shingle line
Ridge or other exhaust venting suited to the attic, with intake at the eaves where possible
New flashing and pipe boots at every penetration

Cost factors

What drives cost on a wind-exposed Washougal roof

The measured area of the roof — counted in roofing squares, not the house’s floor area — sets the base for materials, labor, and disposal. Pitch matters next: a steep roof takes more safety setup and slower work. More hips and ridges mean more linear feet of cap shingles and more edge detailing, and each layer of old roofing that has to come off adds tear-off time and dump weight. Ventilation changes, such as adding ridge vent or intake at the eaves, are their own line items.

Some cost cannot be known until the old roof is off. Wind-driven rain that got under lifted shingles over several seasons can leave soft decking along eaves and rakes. Rather than guessing, the estimate states a per-sheet price for decking, and any damaged areas are photographed and reviewed with you before they are replaced. When you compare bids, a lower number that quietly omits starter strips or proper ridge caps is not really the same roof.

More detail: what affects roof replacement cost and what a roofing estimate should include.

Process

How a Big Bear roof replacement runs

On-site estimate
A roofing specialist walks the roof, checks shingles, flashing, and ventilation, takes photos, gathers measurements, and emails you a detailed estimate.
Review and sign
You go over the written scope and options. When you are ready, you accept the estimate online with an e-signature and we schedule the installation date.
Tear-off and installation
The crew protects the property, removes the old roof, reviews the decking with you where repairs are needed, and installs the new roof system.
Cleanup and follow-up
Debris is hauled away, the property is checked for nails and scrap, and you receive follow-up messages and photo documentation of the work.

Before work starts on your Washougal home

A few steps help the crew focus on the details that hold the roof down.

Share photos and dates of past wind damage and any repairs that followed
If a temporary tarp is on the roof, let us know when and where it was installed
Move vehicles, patio furniture, and grills away from the eaves
Tell us about attic access so ventilation can be reviewed
Secure loose items in the yard that could be disturbed by falling debris

The roof as a system

What goes into a complete new roof

Big Bear focuses on steep-slope asphalt shingle roofs, including architectural shingles and designer lines such as GAF Grand Sequoia. We don’t install flat or low-slope roofing. Exact components depend on your roof’s design, applicable code, and the manufacturer’s instructions.

Decking

The plywood, OSB, or board sheathing the roof is fastened to. It is checked once the old roof is off.

Underlayment and membranes

A water-resistant layer over the deck, with self-adhering membrane at vulnerable areas where specified.

Flashing

Metal at walls, chimneys, valleys, and skylights that turns water back onto the roof surface.

Roof edges

Drip edge at eaves and rakes, and starter courses that seal the first row of shingles.

Penetrations

Pipe boots, vents, and other openings, each sealed to suit the new roof.

Shingles

Architectural or designer asphalt shingles, installed to the manufacturer’s instructions for your roof’s pitch.

Ventilation

Intake and exhaust that suit the attic. What a given roof needs depends on its design, code, and the manufacturer.

FAQ

Roof replacement questions from Washougal, WA homeowners

How does wind exposure change the replacement plan?

It moves attention to the parts of the roof that wind attacks first: eaves, rakes, hips, and ridges. A wind-aware plan specifies starter shingles at the perimeter, drip edge, purpose-made ridge caps, and nailing that follows the shingle manufacturer’s instructions. It also looks at ventilation and flashing, because a roof that resists wind still has to shed water properly at every edge and penetration.

Why do my shingles keep blowing off in the same spot?

Repeated loss in one area usually means the shingles there are no longer sealing to the course below, or they were nailed too high when installed. It can also happen at a rake or ridge that was finished without starter strips or proper caps. An inspection can show whether the issue is local and repairable, or a sign that the whole slope is losing its hold.

Can you put a tarp on my roof after a storm?

Yes. Emergency tarping can keep water out until a permanent repair or replacement is scheduled. Call us at the number on this page and tell us where the damage is. See roof repair and leak repair for more about temporary protection and repairs.

Will my insurance pay for a new roof after wind damage?

Coverage decisions are made by your insurer under your policy, not by a roofing contractor. What we can do is document the condition of the roof with photos and explain what we observed. Contact your insurer before repairs if you plan to file a claim, and keep your own dated photos of the damage.

Should the gutters be replaced during a Washougal roof replacement?

Not always. If they are bent, pulling away, or leaking at the seams, replacing them along with the roof lets the drip edge and gutter line up cleanly. If they are sound, they can often stay. We install seamless gutters when replacement makes sense.
