Reroofing under solar and fixing siding leaks in Sherwood, OR 97140

Sherwood sits in the southwest corner of the Portland metro in Washington County, along Highway 99W southwest of Tigard and Tualatin. From our Vancouver office we cross the I-5 bridge, head south, then cut west. The city has a small Old Town of older homes, but most of its houses went up during a fast growth run in the 1990s and 2000s, and its edges still open onto farms and the hills beyond. The Tualatin River National Wildlife Refuge lies just outside town.
Sherwood homeowners added solar panels in good numbers, often on the original builder roof. Those roofs are now reaching their limit, and the panels have to come off before new shingles can go on. We handle the roofing side of that process and work with your solar company or an electrician on the disconnect and reconnect. Out on the rural edges, our calls lean toward shops, barns and long gutter runs instead.

Sherwood subdivisions, solar arrays and siding joints
Reroofing under solar takes a set order of work. A solar or electrical pro shuts down and disconnects the system where that is required. Our crew then lifts the panels and racking, stores them on site, tears off the old roof, replaces soft decking and installs new underlayment and shingles. Every racking foot gets new flashing tied into that fresh layer, which matters, since poorly sealed mounts cause many leaks on original installs. Shingles under panels often look worse than the rest, because debris and moss built up there for years where no one could reach. Then the panels go back up and the solar pro reconnects the system.
The other leak we trace often in Sherwood is where roof meets wall. Builder homes from this era often skipped kickout flashing at the bottom of roof-to-wall joints, so water runs behind the siding instead of into the gutter. The stain shows up on the siding or on an inside wall below the roofline. Repairing it means opening the siding, adding the flashing, and replacing any rotted sheathing and siding boards before closing the wall back up.
Sun, rain and wind across Sherwood
Sherwood's subdivisions have fewer tall trees than Lake Oswego or West Linn, so many roofs take full summer sun, which bakes builder-grade shingles and dries out rubber vent boots. Then the rainy season sets in, and those weakened shingles and boots let water through. Storms from the southwest cross open farmland before reaching town, and the gusts lift shingle edges on exposed slopes. On rural lots, metal shop and barn roofs lose fasteners and seal washers over time, and long gutter runs fill with debris from nearby fields and hedgerows.
How we plan a Sherwood reroof or repair
We inspect the roof, the attic and the joints between roof and walls, and for solar homes we photograph the array and note the racking type. You get a price for the roofing scope plus panel removal and reinstall, and we coordinate dates with the solar or electrical pro. For outbuildings, we price metal panel repairs or replacement separately. We check City of Sherwood or Washington County permit needs for your address and pull permits where required.

What does solar panel removal and reinstall add to a Sherwood reroof?
On a typical Sherwood home with a residential array, removing, storing and reinstalling the panels on new flashed mounts often adds $2,640 to $5,780 to the roofing price, depending on panel count and racking. The electrical disconnect and reconnect are done by a solar or electrical pro. These are typical ranges, confirmed after we see the array.
Why is the siding below my Sherwood roofline stained and soft?
On many Sherwood builder homes, the bottom of the roof-to-wall joint is missing a kickout flashing, so rainwater runs behind the siding instead of into the gutter. Over a few winters the sheathing and siding rot. We open the wall, install the flashing, and replace damaged boards. Typical repairs run $845 to $2,370, confirmed after we open the wall.
Can you repair the metal roof on my Sherwood barn or shop?
Yes. On rural Sherwood properties we often replace worn screws and seal washers, reseal laps and ridge caps, and swap rusted or bent panels. If the panels are past saving, we price a new metal roof. While we are there we also check any clear skylight panels and the gutters on the building, since both age along with the roof.
