& Leak-Proof PV Integration
San Diego
Plan solar with confidence. TWM Roofing prepares shingle, tile, and flat roofs for leak-proof PV installs, coordinates with your solar provider, and protects warranties across San Diego County.
Why “Solar-Ready” Matters
A PV system is only as reliable as the roof it’s mounted on. Preparing your roof before panels go up protects against leaks, warranty conflicts, and unnecessary re-work later. Our roofing team inspects your existing system, recommends the right prep, and coordinates with your solar installer.
Top homeowner goals we solve:
- Avoiding leaks at standoffs and penetrations
- Choosing the right underlayment and flashing for your roof type
- Sequencing roofing and solar permits/inspections efficiently
- Preserving manufacturer and workmanship warranties
Quick Decision Guide: Reroof Now or Later?
- Roof near end-of-life? Reroof first, then install PV; avoid paying for panel removal/re-install later.
- Roof in good condition? We harden high-risk areas (flashing, underlayment, penetrations) and document everything for your records.
- Unsure? We’ll perform a solar-readiness inspection with photos and a written plan.
Roof-Type Prep: What to Expect
- High-temperature, self-adhered underlayment in critical zones
- Pre-planning for rail standoffs and flashings around ridges/valleys
- Ridge vent considerations for airflow after rail layout
Tile Roofs (Clay/Concrete)
- Underlayment assessment/replacement in work areas
- Tile lift/re-set or “boosted” tile solutions to maintain drainage
- Flashing upgrades around mounts and skylights
Flat/Low-Slope Roofs (TPO/PVC/Mod Bit)
- Proper curb and penetration details specific to membrane type
- Drain and scupper evaluation to keep water moving
- Surface conditioning or coating touch-ups where solar feet contact
Leak-Proofing the Details (Where Most Problems Start)
- Penetrations & standoffs: We use material-specific flashings and sealants; no shortcuts.
- Seams & terminations: Extra attention at laps, edges, and transitions—especially on flat roofs.
- Moisture checks: Optional infrared scan or targeted moisture probing to verify dry substrates.
Warranties & Responsibility—No Gray Areas
We clarify who covers what, roofing materials, workmanship, and PV hardware before work begins. You’ll receive photo documentation of prep work and a simple warranty summary so future service teams know exactly what was done.
Permits, Scheduling & Coordination
San Diego County jurisdictions can vary. We coordinate with your city building department and your solar provider on sequencing (roof prep → solar mounts → final inspections), so you’re not stuck waiting between trades.
Costs & Timelines: What Influences the Budget
- Roof condition and age
- Roof type (shingle/tile/flat) and access
- Quantity and layout of solar penetrations
- Permit requirements by jurisdiction
You’ll receive a clear, line-item proposal with optional upgrades (e.g., high-temp underlayment, added ventilation).
FAQs
Will solar void my roof warranty?
Not if it’s prepared correctly. We use approved flashing and underlayment details and document everything for warranty continuity.
Can I put panels on an older tile roof?
Often yes, but the
underlayment may need replacement in work areas. We’ll advise after
inspection.
Who installs the solar hardware?
Your solar contractor. We handle roof prep, penetrations/flashings, and coordination to protect your roof system.
What if I need a new roof soon?
Reroof first. Removing/reinstalling panels later is more expensive and increases risk.
How long does solar-ready prep take?
Most homes are 1–3 days depending on roof type and scope. We’ll give you a firm schedule.
