Frequently Asked Questions

Most residential roof replacements take one to three days, depending on home size and roof complexity. Weather, material type, and coordination with solar installations can affect timing. At Shadowfax Roofing & Solar, we plan carefully to minimize disruption and ensure quality workmanship throughout the South Bay.

TPO and PVC are both durable single-ply membranes for flat roofs, but PVC offers superior chemical resistance and seam strength. Both materials handle strong sun exposure and temperature fluctuations well, making them ideal for South Bay climates. At Shadowfax Roofing & Solar, we help homeowners choose based on roof layout and long-term goals.

Replace your roof if it has less than 10–15 years of useful life remaining before solar installation. Removing and reinstalling panels later adds significant cost and disruption. At Shadowfax Roofing & Solar, we evaluate roof condition, age, and structure to coordinate roofing and solar work efficiently.

Yes, metal roofing is highly compatible with solar panels and often simplifies installation with specialized mounting systems. Metal roofs offer long lifespans, low maintenance, and energy efficiency that complement solar performance. At Shadowfax Roofing & Solar, we design installations that protect both roof integrity and solar warranties.

Most leaks result from flashing failures around chimneys, skylights, and roof valleys, especially after seasonal rain and heat cycling. Wind-driven rain and aging sealants also contribute to water intrusion. At Shadowfax Roofing & Solar, we diagnose root causes rather than treating surface symptoms to ensure lasting repairs.

Gutter screens block leaves, twigs, and debris from entering gutters, reducing clogs and water backup during rain. They're especially helpful in neighborhoods with trees and seasonal leaf buildup. At Shadowfax Roofing & Solar, we install screens that extend gutter lifespan and improve drainage performance across the South Bay.

Yes, battery systems can be integrated with most existing solar installations to store energy and provide backup power during outages. Proper electrical assessment ensures safe, efficient connection to your home's energy system. At Shadowfax Roofing & Solar, we evaluate compatibility and design battery solutions that support energy independence.

Roof size, material choice, complexity of design, and removal of old layers are primary cost factors. Ventilation upgrades, flashing details, and coordination with solar prep can also influence pricing. At Shadowfax Roofing & Solar, we provide clear evaluations matched to your home style, budget, and long-term needs.

Strong, year-round sun exposure accelerates aging of asphalt shingles and sealants, making heat-resistant materials like metal, TPO, and PVC attractive options. Proper ventilation and reflective surfaces also improve roof lifespan and energy efficiency. At Shadowfax Roofing & Solar, we recommend materials designed for South Bay climate conditions.

Inspect the surrounding roof for wear, flashing integrity, and potential leaks that may worsen during skylight removal. Confirm the new unit fits your roof type and complements planned roofing work. At Shadowfax Roofing & Solar, we coordinate skylight replacements with roof projects to ensure watertight installation and long-term performance.

Without correct slope and drain placement, flat roofs allow water to pool, leading to leaks, membrane damage, and shortened roof life. South Bay rain patterns and roof layouts require careful sizing and positioning. At Shadowfax Roofing & Solar, we focus on seam integrity and drainage to prevent water-related failures.

Many homeowners delay repairs or address only visible symptoms without identifying underlying causes like flashing failures or ventilation issues. This leads to recurring leaks and costly interior damage. At Shadowfax Roofing & Solar, we use thorough diagnostics to fix root problems and extend roof life across San Jose-area homes.
