Golden House

Santa Rosa, CA

Overview

This home’s position left its front side constantly exposed to the conditions that moss and lichen love — and the old shingles showed it. Years of growth and darkening had stained the surface and were quietly speeding up the deterioration of the roof. The good news: the field of the roof hadn’t started leaking yet. The bad news: the valleys and dormers had, and someone had tried to patch them in ways that were never built to last.

Our job was to give this home a roof that solved the problems underneath, stood up to the conditions the home is exposed to, and looked like it was always meant to be there.

What We Found

 The roof made its problem areas pretty clear:

• The front-facing slope had heavy moss and lichen growth, with darkening and staining that was accelerating shingle deterioration well ahead of schedule.
• The valleys showed signs of past water intrusion and prior patch attempts that weren’t built to hold up long-term.
• The dormer sites had similar issues, with sidewall flashings that hadn’t been installed correctly the first time around.
• Existing ventilation and penetration flashings were due for an update to match a new roof system.

What We Did

We started with a full tear-off and installed GAF HDZ shingles in Copper Canyon across the entire roof, paired with new synthetic underlayment for a stronger, more reliable base than the old felt could ever provide. Special attention went to the problem areas: every valley got GAF WeatherWatch ice and water shield to lock in long-term leak protection, and the dormers received the same WeatherWatch treatment along with proper step flashing run all the way up the sidewalls — the way they should have been installed from the beginning. New ventilation went in to keep the new system breathing properly, and every penetration flashing was replaced and painted to match the Copper Canyon shingles. To finish it off, the nosing flashings were painted to blend seamlessly into the existing fascia and gutter colors, so the new roof reads as part of the home rather than something stuck on top of it.

Why It Matters

A roof’s biggest enemies aren’t always the ones you can see from the driveway. Moss and lichen quietly eat at shingle life on shaded slopes, and bad valley or dormer flashings can leak for years before the damage shows inside the home. Catching those issues now — and addressing them with the right products in the right places — is the difference between a roof that lasts a decade and one that lasts the full warranty. The detail work on the flashings is what makes the whole thing look like a finished piece of work instead of a parts list.

The Result

A roof that solves the leaks the previous installer never properly fixed, stands up to the moss-prone conditions this home faces, and ties together with the existing fascias, gutters, and home aesthetic in a way that feels intentional. The client was very satisfied — and walked away with a roof system that looks as deliberate as it performs.
