A roof replacement from NRG is a full tear-off and re-roof: deck inspected, synthetic underlayment down, all new flashings, and architectural or presidential composition shingle on top. Firm written bid, 5-year written workmanship guarantee. Serving Ventura, Oxnard, Camarillo, and all of Ventura County.
"If it's our workmanship, we fix it. That commitment is on paper before we ever touch your roof."
A new roof is a system. Skip a layer and the shingles on top don't matter — so we don't skip layers.
The old roofing comes off down to the deck and gets hauled away. No second layers, no shingling over problems that show up again in five years.
With the deck exposed, we inspect every sheet. If we find rot or damage, you get photos and a price for the repair before it's covered up — not a surprise on the final bill.
Modern synthetic underlayment across the whole deck — the water barrier that does the real work when wind drives rain under the shingles.
Chimneys, walls, valleys, vents, and skylights get new flashing — reusing tired flashing on a new roof is where most "new roof still leaks" stories start.
Architectural or presidential composition shingle, installed to manufacturer spec by our own crews — no brokered-out work, no mystery subs on your roof.
Tear-off is messy work — our crews clean the site daily, and you get a finished roof, a tidy yard, and your written workmanship guarantee at the end.
We quote the systems we self-perform and guarantee — and if your project calls for something we don't install, we'll tell you that straight.
The workhorse of Ventura County re-roofs — dimensional laminated shingle with a clean profile and strong wind performance. The value pick for most homes.
Heavyweight, shake-style presidential shingle for a thicker shadow line and a premium look — a popular step-up on view homes and higher-end remodels.
Torch-down modified bitumen and waterproof deck systems for the flat sections, patio roofs, and walkable decks that many Ventura homes carry alongside the main roof.
Repair-first is the house rule. If your roof has years of life left and a flashing repair or a shingle section will solve the problem, that's what we'll quote — not a full replacement you don't need yet. When a roof genuinely is at end of life, we show you the evidence in photos and give you both numbers: the repair now and the replacement later. The decision stays yours, made with real information.

We come out, get on the roof, and do a real measured takeoff — slopes, penetrations, flashing conditions, and the state of what's under the shingles. Not a drive-by square-footage guess.
A written scope of work and a firm price, with allowances spelled out and the 5-year workmanship guarantee attached — before you sign anything. No lowball-then-change-order routine.
Our own crews tear off, repair what the deck needs at the prices already agreed, install the new system, and clean the site daily until the job is done.
It depends on four things: the size of the roof, the pitch and complexity, the material you choose (architectural vs. presidential composition shingle, and any flat sections), and the condition of the sheathing underneath. That's why we don't quote prices over the phone — we do a measured takeoff and give you a firm, written bid, so the number you sign is the number you pay. No surprise change orders.

Most single-family re-roofs are completed in 2-5 days depending on size, roof complexity, and weather. Larger or steeper roofs take longer — your written bid includes a specific schedule for your house, so you know before we start.
No — most homeowners stay home. Tear-off days are the loud ones, so if you work from home you may want to plan calls around them. We keep access clear and clean the site daily, so living around the project is manageable for the few days it takes.
It covers our workmanship — defects in how we installed your roof, like a leak caused by improper flashing work. It's a 5-year term, provided in writing on every estimate before you sign. It's not a lifespan claim on the roofing material itself; the shingle manufacturer warrants the product, and we stand behind our labor.
