Roof Installation in Pasadena - Written Price, Workmanship Warranty

Trusted Roof Installation for Pasadena Homeowners

A new roof in Pasadena typically costs between $9,800 and $24,000 depending on material, square footage, and whether the old roof needs tearing off first. Most full installations we do in Pasadena take three to five working days from tear-off to final inspection. Crestview Roofing Co Pasadena has handled residential roof work across the San Gabriel Valley since 2000, and we put every price, timeline, and warranty in writing before any work starts. If you’re weighing a roof installation and want real numbers instead of a vague sales pitch, call (626) 389-1956. We answer the phone.

Dylan Pace set this company up so homeowners would never have to guess what a roof job costs. The written price you approve is the price on the invoice. No change orders, no “we found some rot” upcharges, no surprises at the door. That’s the Relay Visibility Guarantee, and it governs every roof we install in Pasadena.

Shingle Roof

A Shingle Roof is the most common residential roofing system in Pasadena, built from overlapping asphalt shingles secured over a waterproof underlayment. You need a new shingle roof when your existing shingles show granule loss, curling edges, or bald spots where the fiberglass mat shows through, or when the roof has passed the 20-25 year mark. Crestview Roofing Co Pasadena installs architectural and three-tab shingle systems from GAF, CertainTeed, and Owens Corning, with a full tear-off, new underlayment, drip edge, and flashing. A complete shingle roof installation in Pasadena runs $9,800 to $18,500 for a typical 1,400-2,200 square foot home, depending on pitch, height, and how many layers we have to remove first.

Architectural vs. Three-Tab

Architectural shingles are thicker, hold up better in Pasadena’s summer UV, and carry a 30-year to lifetime manufacturer warranty. Three-tab shingles cost less upfront but typically last 15-20 years and are easier to lift in high wind. For most Pasadena homes, architectural shingles are the smarter long-term buy.

Underlayment and Deck Inspection

Every shingle roof we install includes a full deck inspection after tear-off. If we find rotted plywood or OSB, we photo-document it, show you the exact square footage, and give you a per-sheet replacement price on the spot. You’ll never pay for board replacement you didn’t approve in advance.

Standing Seam Metal Roof

A Standing Seam Metal Roof uses vertical metal panels with concealed fasteners that lock together along raised seams. You need this type of roof when you want a 40-60 year service life, higher fire resistance, or a modern architectural look on a Pasadena mid-century or contemporary home. Crestview Roofing Co Pasadena installs standing seam systems in 24-gauge steel and aluminum, including custom trim, ridge caps, and snow-snap accessories for roof-mounted solar or HVAC. A standing seam metal roof installation in Pasadena runs $18,000 to $35,000 for an average single-family home, making it the highest upfront cost of our common systems, but the payoff is longevity and low maintenance.

Solar and Metal Roof Compatibility

Standing seam metal is the best roofing choice if you plan to install solar panels. Panels clamp directly to the seams without any roof penetrations, which means no screw holes, no future leak points, and no voided roof warranty. If solar is on your five-year plan, this is the roof that plays well with it.

Fire Safety and Pasadena Hillside Requirements

Pasadena hillside neighborhoods in the foothill zone often require Class A fire-rated assemblies. Standing seam metal is one of the few roof systems that meets that requirement without a specialty underlayment. We handle the permit coordination and can confirm your specific hillside requirements before you commit.

Tile Roof

A Tile Roof is a roofing system built from clay or concrete tiles, either in the style of Spanish barrel tiles, flat shingle tiles, or interlocking low-profile tiles. You need a tile roof installation when your existing tile roof has widespread cracked tiles, when the underlayment beneath the tiles has failed, or when you’re building or buying a home in a Pasadena neighborhood where tile fits the architectural character. Crestview Roofing Co Pasadena installs and repairs tile roof systems throughout Pasadena, Altadena, and San Marino, working with Boral concrete tile and traditional clay tile from major manufacturers. A full tile roof installation in Pasadena runs $15,000 to $32,000, with concrete tile at the lower end and clay at the higher end.

Underlayment is Everything on Tile

Tile itself is mostly decorative protection; the real waterproofing is the underlayment system underneath. We install double-layer underlayment on every tile roof, which extends the roof’s functional life significantly. The tile lasts decades; the underlayment is what you’re actually replacing every 20-30 years.

Structural Load and Truss Review

Tile is heavy, at 600-1,100 pounds per roofing square depending on material. Before we quote a tile roof in Pasadena, we check your truss spacing and load capacity. If your home was originally built for shingles, we’ll tell you whether it needs structural reinforcement before the tile goes on. We won’t put a heavy tile system on a roof that can’t carry it.

Roof Ventilation

Roof Ventilation is the intake and exhaust airflow system that keeps the underside of your roof sheathing at a stable temperature and moisture level. You need proper roof ventilation in Pasadena when your attic hits 130-150 degrees in summer, when you see condensation on the underside of sheathing in the winter, or when your air conditioner runs constantly and your second floor stays hot. Crestview Roofing Co Pasadena installs ridge vents, soffit vents, gable vents, and powered attic fans as part of a comprehensive roof installation. A complete roof ventilation system installed during a re-roof in Pasadena runs $600 to $2,500 depending on roof size and the number of vents required.

Balanced Intake and Exhaust

Ventilation only works when intake and exhaust are balanced. A ridge vent needs matching soffit vents, otherwise it pulls air from the living space and short-circuits the airflow. We calculate net free vent area against your attic square footage, and we’ll show you the math before we cut any holes.

Ventilation and Shingle Warranty

GAF and CertainTeed both write ventilation requirements into their warranty fine print. An overheated attic degrades shingles from underneath, cuts their lifespan, and can void your manufacturer warranty. We build proper ventilation into every shingle roof installation so your materials are protected both from the weather and from your attic heat.

Roof Flashing Installation

Roof Flashing Installation is the process of sealing the roof’s vulnerable seams and transitions with metal strips, namely around chimneys, walls, skylights, valley intersections, and plumbing vent pipes. You need flashing installation when you’re putting on a new roof, when you see water stains on ceilings near a chimney or wall intersection, or when old flashing is cracked, rusted, or lifting. Crestview Roofing Co Pasadena installs flashing as part of every roof installation we do in Pasadena, using galvanized, aluminum, or copper flashing matched to the roof material. Flashing installation as a standalone repair runs $350 to $950 per penetration point; as part of a full roof installation, flashing is included in the system price.

Chimney and Sidewall Transitions

Chimney flashing involves two layers, the step flashing against the brick and the counter flashing cut into the mortar joint. If either layer is missing or improvised with caulk, water will find its way in. We install both layers, plus a cricket behind the chimney if the chimney face is wider than 30 inches.

Valley Flashing Options

Valleys are the V-shaped seams where two roof planes meet, and they carry more water than any part of the roof. We install either open metal valleys or closed woven valleys depending on the roof system and slope. On Pasadena homes with steep multi-plane roofs, we’ll recommend the style that’s least likely to clog with debris and back water up under the shingles.

TPO Roofing Installation

TPO Roofing Installation is the installation of a Thermoplastic Polyolefin membrane, a white single-ply roof system most common on flat and low-slope roofs. You need a TPO roof in Pasadena when you have an addition, garage, or flat-roof section that can’t shed water on its own, or when an old tar-and-gravel or modified bitumen roof has reached the end of its life. Crestview Roofing Co Pasadena installs TPO systems from major single-ply manufacturers, heat-welding the seams for a watertight bond rather than relying on adhesives. A TPO roof installation in Pasadena runs $7,500 to $13,500 for a typical flat garage roof or addition, depending on insulation needs and parapet wall conditions.

Heat-Welded Seams vs. Adhesive

TPO membranes should be hot-air welded at the seams, not taped or glued. A welded seam fuses the membrane into a single piece, and that’s what keeps a Pasadena flat roof watertight through heavy winter rain. We weld every TPO seam and then probe-test the welds to confirm they’re solid before we walk away.

Reflectivity and Cooling Efficiency

White TPO reflects a large portion of the sun’s heat instead of absorbing it, unlike dark modified bitumen. On a flat-roof addition or sunroom in Pasadena, that keeps the space beneath the roof cooler, which means less load on your AC. If you’re replacing an old tar-and-gravel roof, you’ll notice the difference that same summer.

Brands We Service

We install and stand behind GAF shingle systems, including the Timberline and Grand Sequoia lines, and we’ve built our process around GAF’s strict installation specs so your warranty stays viable. We can also provide the GAF Golden Pledge warranty on qualifying full roof installations, which extends the manufacturer coverage well beyond the standard term.

CertainTeed shingles are a frequent choice for Pasadena homeowners who want the wide color range and the NorthGate or Landmark lines. We handle CertainTeed installations the same way, including their exact nailing patterns and ventilation requirements. Owens Corning systems, particularly the Duration line with its SureNail technology, are another strong option we install regularly. Whether you have a GAF roof, a CertainTeed roof, an Owens Corning roof, or any other make, we can help.

Signs You Need a Pro Right Now

• Ceiling stains that grow after rain. A brown water ring on your living room ceiling means water is already getting through the roof deck. What you see on the inside is usually far from the point of entry, and by the time it stains the drywall, it’s been working for a while. The sooner you call a professional in Pasadena, the less structural damage you’ll pay to fix.
• Granules in your gutters. If you’re pulling handfuls of asphalt granules out of your downspouts, your shingles are shedding their protective coating. That granule loss exposes the asphalt to UV light and accelerates the roof’s decline. It rarely reverses itself.
• Curling or lifted shingle edges. When shingles curl at the edges or lift in the wind, moisture gets underneath them. That’s how you end up with rotted sheathing and leaking underneath a roof that still looks acceptable from the street. A few curled shingles in one area usually signals the whole slope is aging.
• Daylight visible in the attic. If you can see points of light through the roof boards from inside your attic, you’re also seeing water entry points. Hold up a flashlight in the attic on a bright day and look. Pinholes of light mean the roof’s waterproofing barrier is compromised.
• Neighbors getting re-roofed, and your house is the same age. Pasadena neighborhoods built in the same tract tend to wear out on the same timeline. If the homes on your block are all getting new roofs and yours is still original, it’s not that your roof is better; it’s that it hasn’t been inspected yet.

Our Process, Step by Step

1. 1
   Phone consultation and measurements. Call us at (626) 389-1956 and we’ll talk through what you’re seeing, what you’re looking for, and what your budget range is. We’ll schedule a site visit and confirm a live arrival time you can track through The Relay Standard, so you know exactly when we’ll be at your door in Pasadena.
2. 2
   On-site inspection and roof measurement. We walk the roof, measure every plane with a laser or tape, and inspect flashings, penetrations, and sheathing condition. You get a written report with photos of anything that matters. If the roof is unsafe to walk, we’ll say so and use a drone to inspect instead.
3. 3
   Written line-item quote. The written price comes before any work starts. It has each scope item broken down with its own cost, from tear-off to disposal to new underlayment to materials and labor. If we find something during the inspection that could affect the price, like rotted decking or a bad truss, it’s already on the quote with a per-sheet or per-foot price.
4. 4
   Installation day. Our crew arrives with the material, protects your landscaping and exterior walls, and gets to work. You’ll get before photos at the start of the day and after photos when we’re done. We haul away every piece of old roofing and magnet-sweep the yard for loose nails before we leave.
5. 5
   Final walk-through and digital invoice. We walk the finished roof with you, answer any questions, and verify the work matches the written quote. Your invoice is sent by text. Your warranty, the 365-Day Done Right Promise, is included on every installation, in writing, for a full year.
