Fast, Reliable Roof Replacement Across Mountain View
If your Mountain View roof has started leaking into ceilings you just painted, or a roofer told you the whole thing is shot without showing you why, we can give you a straight answer. Sunstone Roof Repair works across Mountain View, from the flat-roofed postwar tracts on the north side to the pitched homes climbing toward the Santa Cruz foothills, and we know those two roof types fail in completely different ways. You get a real diagnosis and a written estimate, not a replacement pitch dressed up as a safety warning. Call (855) 473-8840 and we’ll set up your free estimate.

Why Mountain View Homeowners Call Sunstone Roof Repair for Roof Replacement
Most people who call us in Mountain View aren’t shopping for a contractor. They’ve got a stain on a ceiling, a shingle pile in the gutter after a stiff wind, or a flat roof that holds a puddle in the same corner every January. What they want first is an honest read on whether it needs a repair or a whole new roof. That’s why we offer a roof replacement inspection as a standalone service, with no obligation to buy anything afterward.
We install across seven major material lines, including GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, so your recommendation comes from what the house actually needs rather than what a supplier happens to be pushing that month. Our technicians have up to 12 years of experience, and that matters on a Mountain View roof because the two dominant house types here need genuinely different systems. If a contractor quotes you a single product for every house on the block, that’s a sign they haven’t looked closely enough.
When you call and someone is out that day, you get a fixed scope laid out line by line: tear-off, deck repairs, underlayment, flashing, permits. No change orders halfway through for work that should have been in the first bid. We answer 24/7, with fast dispatch from 7am to 7pm, Sunday through Friday.

New Roof Installation in Mountain View
New roof installation in Mountain View usually means replacing the entire assembly down to the decking, not just laying fresh shingles over the old surface, because most of the housing stock from the 1950s through the 1970s wasn’t built to carry two layers. That includes stripping the old roof, inspection and replacement of any soft sheathing, new underlayment and flashing, and a full system topped with products from GAF, CertainTeed, Owens Corning, or another of the manufacturers we install. Typical cost for a complete new roof in Mountain View runs roughly $19,000 to $38,000 depending on square footage, pitch, and whether the deck needs significant repair. We’ll tell you exactly what your roof needs. Estimates are free.
What a Full Replacement Covers
You can expect tear-off and disposal, deck inspection with soft spots addressed, a code-compliant underlayment, new drip edge and valley flashing, and new ridge and vent components. For hillside homes toward the Santa Cruz foothills, the spec includes rated underlayment and a nailing pattern matched to the shingle’s wind rating, not just what’s fastest. The final walk covers both the roof and the gutters, because on a Mountain View house, a new roof and clear drainage are the same job.
Choosing the Right Material for Your Roof
Architectural shingles from GAF or CertainTeed suit most of the pitched hillside homes and satisfy the wind-load requirement a new install has to meet. On the flat-roofed north-side homes, membrane and cool-roof systems are the better fit because they handle ponding water and reflect the long UV season. We recommend based on your climate, your budget, and the existing roof system, not a fixed brand.
Reroofing in Mountain View
Reroofing in Mountain View is the term for replacing the roof covering on an existing structure, and here it splits into two very different jobs that share the same word. On hillside homes toward the Santa Cruz foothills with steep pitches, reroofing means wind-rated shingles and a nailing pattern that matches the exposure, because that’s where storm damage originates. On the flat roofs on the north side, it generally means stripping to decking, correcting drainage slope, and installing a new membrane where tar-and-gravel once sat. Reroofing in Mountain View typically runs $14,000 to $28,000 for a standard house, and $20,000 to $35,000 for a membrane retrofit with drainage corrections. Get a free written estimate before you commit.
Overlay Versus Full Tear-Off
Some bids offer to lay new shingles right over the existing layer. That saves money up front, but it hides the decking, and on a 1960s Mountain View house the decking is exactly what needs eyes on it. Most cities also limit how many layers a roof can carry, so ask your city’s building department before assuming an overlay is allowed. We recommend a full tear-off unless the existing roof is truly a single sound layer.
Drainage Corrections on Low-Slope Roofs
On the flat-roofed homes, standing water is concentrated at the low spots that form over decades of settlement, and it attacks the flashing and seams before it ever gets to the membrane itself. A proper correction means adding tapered insulation or a new slope scheme so water moves off the roof in one direction. That step has to go into the quote, not appear as a surprise mid-job.

Trusted Brands We Service in Mountain View
We install and work with materials from GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, which gives us real choice rather than a single-brand pitch. We don’t run a parts warehouse or keep stock on hand, so we specify and source exactly what your roof needs once the inspection is done. Because a Mountain View job is often a mix of pitched roof and flat-roof sections, being fluent across all these systems means we can match new material to what’s already on your house. Fast turnaround, honest spec, one contractor.

AfterCommon Roof Replacement Problems We See in Mountain View Homes
- Ponding at settled low spots. On original tar-and-gravel flat roofs, decades of settlement leave water gathering in the same few places after a storm. Standing water works on flashing and seams and can turn a patch job into a full replacement.
- Wind uplift on exposed hillside pitches. Ridges, valleys, and eaves on the steeper foothill homes take the brunt of a gust front. When the nailing pattern doesn’t match the shingle’s rated wind speed, shingles lift and peel instead of holding.
- UV-aged membrane and dried-out flashing. The long dry season bakes the surface, and old flashing around penetrations and skylights cracks. The next concentrated winter rain goes straight into decking and up into ceilings.
- Soft decking under old layers. On postwar tract homes, slow leaks often go unnoticed until the sheathing is rotted through. Any quote that skips the decking inspection is an incomplete quote.
Pricing for Roof Replacement in Mountain View, CA
A full roof replacement in Mountain View typically runs $19,000 to $38,000 for a complete teardown and rebuild, while a reroof over an existing structure runs $14,000 to $28,000.

FAQs About Roof Replacement in Mountain View
Your new roof has to meet the wind rating set by local building codes and the shingle’s own manufacturer spec, and those two numbers both matter. Most cities require a permit and an inspection for a full replacement, so we check the current local requirement with your city’s building department and spec the shingle to match. That’s why the nailing pattern and rated underlayment go in the bid, not the fine print. Call (855) 473-8840 to schedule your free estimate.
No, a reroof that goes straight over a ponding tar-and-gravel surface just traps the problem and lets it push at the new membrane from underneath. The usual correction is to strip to decking, inspect and replace any soft sheathing, add tapered insulation or a slope scheme to restore positive drainage, then install new membrane with fresh flashing and rebuilt fascia and soffit. It’s a different job from what the hillside homes need. Call (855) 473-8840 for an honest assessment.
A compliant quote should include the permit and inspection, the decking condition, the underlayment spec and flashing, the nailing pattern and shingle wind rating, and any drainage corrections. A cheap bid often skips the deck inspection and the permit, quoting the visible shingle job and leaving the parts you can’t see for later. Ours is written line by line, so nothing gets added after the work starts. Call (855) 473-8840 and we’ll walk through the scope with you.
Yes, documented compliant work gives you a record of what was installed, when, and to what spec, which is what your insurer wants if you ever file a claim. We hand you the permit record and the material specification so you can present that to your insurer. We can also work with your insurer if a storm claim comes up. Call (855) 473-8840 for a free estimate.
A hillside re-roof is a pitched-system job where wind uplift at ridges and valleys drives the spec, so the nailing pattern and rated underlayment matter as much as the shingle. A north-side flat roof is a membrane job where the original tar-and-gravel has usually settled and ponded, so the drainage has to be corrected before anything goes down. Same trade, two different products and two different drainage corrections, and the permit submittal has to match whichever one the house actually is. Call (855) 473-8840 for your free estimate.
