Roof Repair, Replacement, and More for Glen Ellen Homes

Homes along Arnold Drive, near Glen Ellen Village, and out toward Warm Springs Road often have a mix of composition shingles, tile, metal, and older roof systems. Some properties have big trees close to the roof, which can leave branches, leaves, and shade that hold moisture.

In Sonoma Valley, the roof takes heat during summer and hard rain during winter. That back-and-forth can crack sealants, loosen flashing, and wear down older shingles. We help Glen Ellen homeowners decide whether a clean repair, a roof inspection, or a full roof replacement is the right next step.

Start with what your roof needs

A property’s address or age alone does not tell us whether it needs a repair or a new roof. Tell us about leaks, earlier work, and the material if you know it. We assess the condition and explain the proposed work so you can make a decision with useful information.

• Leak diagnosis and repair for new or returning water entry.
• Roof replacement when a wider project makes sense.
• Roof inspections to understand the condition before deciding.
• Commercial roofing with access and building use in mind.
• Gutters and skylights connected to the roof system.
