How Cenvar Makes Sense of the Sun + Shingle Mash‑Up

Your Question

Cenvar’s Plain‑English Answer

“Tesla tiles, GAF shingles, or REC panels: what’s best?”

We crunch cost‑per‑watt, roof angle, and warranty fine print, then hand you a simple estimate.

“Will my roof leak?”

Not on our watch. We’re roof pros first; every mount and flashing gets the same craftsmanship as the shingles.

“Who does the paperwork?”

We wrangle permits, utility interconnects, and that 30 % federal credit: you just sign once.

“What if something breaks?”

Single‑number support: our workmanship warranty + REC ProTrust (or equivalent) means no finger‑pointing.

Bottom line: flashy breakthroughs hit headlines every decade, but Cenvar keeps it real: combining the toughest roof systems with proven solar brands so your house starts printing sunshine without the drama.
