Shingle Roof Replacement Upland November 2026

Torn Off to the Deck:
An Upland Roof Replacement

This one is in progress. A single-story home in Upland, CA with a shingle roof at the end of its life. We tore it off to the deck, replaced the bad wood, and the underlayment is going on now. Owens Corning Duration COOL shingles go on next. Here's where it stands.

Why This Roof

Age. The old shingle roof was at the end of its life, so this is a full replacement, not a repair. How I tell the difference is in repair vs replacement.

November 11: Torn Off, Deck Fixed, Underlayment Going On

Every shingle job we do is a full tear-off. The old roof came off down to the wood, because that's the only way to see the deck. On this one we found bad wood, and we replaced it. The lighter sheets in the photos are the new plywood.

Then the underlayment. The steeper slopes get Owens Corning ProArmor. The low slope on the back of the house gets Titanium peel and stick instead. Water drains slower off a low slope, so that section gets a membrane that sticks to the deck.

Done Before the Rain

Rain is in the forecast for Friday. This roof will be finished before it gets here. What we do when rain shows up and a roof is open is in this post. I'll add the finished roof here when we wrap up.

You can't see the deck until the old roof is off. That's why we tear off every time.

Another Duration COOL roof we finished: a shingle roof replacement in Fontana. More of our work in town is on our Upland page.
