One layer, not two
Roofing over an old layer hides a rotten deck and adds weight. We tear off unless there is a specific reason not to, and we will name that reason.
ROOFING · SHINGLES
Asphalt Shingle Roof Replacement
Architectural asphalt is still the right roof for most Eastside houses: quiet, repairable, and at home next to cedar and Hardie. We tear off to the deck, replace soft plywood, and install a system — underlayment, ice-and-water in the valleys and eaves, starter, hip and ridge — not just a new color of shingle on a tired felt layer.
Included in this scope
- Tear-off of the old shingles and worn underlayment
- Sheathing repair where the deck is soft
- Synthetic underlayment and ice-and-water membrane at eaves, valleys and penetrations
- Architectural shingles, starter strip, and hip-and-ridge
- New pipe boots, vents and step flashing at the walls
Details that change the result
Valleys take the water
A woven or metal valley is a design choice with a water reason behind it. We do not leave an open valley to “look rustic” on a house under firs.
Color versus algae
North slopes grow moss. A shingle with algae resistance helps on the south and does less under deep shade. We talk about the trees, not only the brochure.

Questions
Before you call
How long do architectural shingles last here?
The carton says 30 to 50 years. Shade, moss and skipped flashing shorten that. A roof we can stand behind is one with the deck and the metals done, plus a plan to keep debris off it.
Can you match a few slopes?
A repair slope can be matched closely. A full replacement should be one shingle, one color, one age. Patchwork roofs leak at the seams between eras.
What about the gutters?
We reset or replace gutters when the roof edge changes, and we say so in the estimate. A new roof draining behind a collapsed gutter is not finished.
