Frequently Asked Questions
Is a new roof a tax write-off in California?
A standard roof replacement is a capital improvement, meaning it adds to your home’s basis but is not a direct current-year tax deduction.
However, if you install energy-efficient upgrades during the project—such as qualifying skylights or advanced attic insulation—you can claim the federal Energy Efficient Home Improvement Credit for up to 30% of those specific component costs through 2026.
How do I stop moss and algae from growing on my shaded Mill Valley roof?
Mill Valley’s coastal fog and heavy redwood canopies create a damp environment perfect for moss and blue-green algae, which actively degrade asphalt.
Capstone Roofing installs GAF Timberline HDZ shingles featuring StainGuard Plus technology, utilizing time-release copper capsules to continuously fight off algae growth.
Does coastal salt air in Mill Valley cause roof corrosion?
Yes, the salty marine layer can embed into porous surfaces and accelerate corrosion on metal roofing components and fasteners.
We use specialized, corrosion-resistant underlayments and high-grade flashing to ensure your roof withstands Mill Valley’s coastal conditions.
Can you replace gutters during a roof replacement in Mill Valley?
Absolutely. Mill Valley’s heavy organic tree debris quickly clogs standard gutters, leading to water backing up under the roofline. Capstone Roofing seamlessly coordinates high-capacity gutter replacements alongside your new roof installation to ensure total water management.
