Straight quote
We look at the whole roof — including ventilation — and give you an honest, competitive price.
On time, on budget
The crew shows up when we say, does quality work in the timeline and budget we quoted, and leaves the site clean.
Five stars. Every single review.
Whidbey homeowners keep saying the same things — on time, on budget, and details done right.
“As someone who has personally installed 3 roofs myself on other homes I’ve had, I really appreciated the level of detail to do things right with some small items that get overlooked or skipped by others who are in a rush to just get a profit. … their price was very competitive and the best value of all the quotes I found.”
“The professionalism and timeliness of service has been second to none. I do not think I will use anyone else when it comes to my roof. A huge thank you to Zach and his team”
“Our ventilation had been screwed up by 2 other companies leading to high moisture content in the wood … Thankfully Sean was able to fix the ventilation and we’re doing a lot better. … I wouldn’t trust my roof to anyone else, it is so integral to the health of your home”
“In this day and age it’s great to find a company that shows up on time, does quality work in the timeline and budget they said. A+”

A roof is a system. We build the whole thing right.
Shingles are the part you see — but on Whidbey, what makes a roof last is everything underneath: ventilation, moisture control, flashing, the details that get skipped by crews racing to the next job. That's the work customers hire Zach, Sean and the Advantage crew to get right — reviews talk about roofs other companies got wrong being fixed for good. Real office in Oak Harbor, real people when you call.
