How Your Shingle Installation Works
Three steps. No surprises.
Free Roof Assessment
We measure the roof, check the decking and ventilation, and take photos. Most assessments take 30 to 45 minutes.
Estimate and Material Choice
Line-item pricing with the shingle line, underlayment, and warranty in writing. You pick the color and tier. No vague lump sums.
Professional Installation
Most homes are torn off and re-roofed in one to two days. We protect the property, haul the old material, and leave the site clean.
Shingle Systems We Install
Architectural Shingles
The standard for Eastside homes. Dimensional, wind-rated, and available in the colors buyers actually want.
3-Tab Shingles
A budget-friendly option for rentals and simple roofs. We will tell you honestly when it makes sense and when it does not.
Designer and Premium
Luxury profiles that mimic slate or wood shake. Heavier, longer-rated, and built for homes where the roofline matters.
Full Tear-Off and Re-Roof
We strip down to the deck so we can see and fix what is underneath. No shingling over old problems.
Underlayment and Ice Shield
Synthetic underlayment plus ice and water barrier in valleys and eaves. This is what keeps a wet-climate roof dry.
Ventilation and Flashing
Proper intake and exhaust plus new flashing at every penetration. Done right, this is what gets you the full lifespan.

Frequently Asked Questions
How long does a shingle roof installation take?
Most King County homes are torn off and re-roofed in one to two days. Larger or steeper roofs, or jobs that need deck repairs, can run a third day. We give you the timeline in the written estimate.
What shingle brands do you install?
We install GAF and CertainTeed architectural shingles as our standard, plus their designer and premium lines. Both carry strong manufacturer warranties when installed by a certified crew, which is what we are.
How long do asphalt shingles last in the Pacific Northwest?
Architectural shingles typically last 25 to 30 years here when installed with proper ventilation and flashing. Moss and constant moisture shorten that if the roof is neglected, so annual cleaning and gutter care matter.
Do you tear off the old roof or install over it?
We tear off down to the deck. Shingling over an old layer hides rot and voids most manufacturer warranties. Stripping it lets us inspect the decking and start the new roof on a sound surface.
Do you charge for the inspection or estimate?
No. Both are free. You get a photo report and a written, line-item estimate whether you hire us or not.
Do you warranty the installation?
Yes. Every install carries a written workmanship warranty from us, and the shingles carry the manufacturer warranty separately. We hand you both documents on completion.
Ready for a Roof That Lasts?
A shingle roof installed right outlives one installed cheap by a decade. We will inspect for free, send photos and a written estimate with your material options, and only do the work if it makes sense for your home.
