Fast, Reliable Roof Replacement Across Montclair
Roof replacement in Montclair usually means opening up a postwar roof and finding more than the shingles you can see from the street. Most homes here were built between the 1950s and early 1970s, and many have two or even three layers of old roofing stacked on top of each other. That changes the scope of the job before a single new shingle goes down. We know that because we’ve torn off enough Montclair roofs to expect it. If you’re seeing stains on the ceiling or missing shingles after a Santa Ana wind, call (877) 731-1384 and we’ll start with a straight diagnosis, not a sales pitch.
Why Hawk Roof Repair Is Montclair’s Preferred Roof Replacement Company
Montclair homeowners call us because we inspect first. Every time. We don’t climb a ladder and start quoting squares before we know what’s under the top layer. Noel Ibarra built Hawk Roof Repair around that principle: document the condition of the roof, show the homeowner what’s actually failing, then talk materials and price. That approach matters more in Montclair than in newer cities, because what’s under the surface here is rarely simple.
We work throughout the 91763 zip code, from the tract homes near Monte Vista Avenue up through the neighborhoods around Mills Avenue and south toward Ramona Avenue. Our crews know these houses. Same floor plans, same roof pitches, same aging felt-and-tar flat sections that pond at the low spots after a hard winter rain. That familiarity means we spot problems faster and quote them accurately.
We’re headquartered nearby in Ontario, so we reach Montclair quickly and we’re back for follow-up work without a long drive. Our Montclair customers tend to stay with us after the first job, because we show them photos of the tear-off, the decking, the flashing, and every line of the contract before we spend their money.
Styles & brands we work with






Asphalt Shingle Roof Replacement in Montclair
Asphalt Shingle Roof Replacement in Montclair typically runs $9,800 to $16,400 for a standard single-story ranch or stucco tract home, depending on how many old layers we’re stripping and what condition the decking is in once we open it up. This is the most common replacement we do in Montclair’s 1950s-to-1970s subdivisions, where moderately pitched roofs with original or early-reroof composition shingles are everywhere.
An asphalt shingle replacement here usually involves more than swapping shingles. We strip down to the decking, inspect the wood for saturation and rot, replace damaged decking, install new underlayment, and then lay the shingles with new drip edge and flashing. Montclair’s summer heat means we pay close attention to attic ventilation at the same time, because new shingles on an under-ventilated attic will age out years early.
We offer asphalt shingles from GAF, CertainTeed, Owens Corning, and Atlas, among others. The choice is yours based on look and budget, not on whatever brand we happen to have on hand.
Decking and Underlayment Replacement
On older Montclair roofs, decking replacement is common once the old layers come off. Two or three stacked roofs trap moisture against the wood for years. We inspect every sheet and replace anything that’s soft, stained, or delaminated, priced in writing before we touch it.
Underlayment is just as important. We don’t reuse old felt or skip sections to save time. New synthetic underlayment goes down before the shingles, and we pay extra attention to valleys and eaves, where Montclair’s Santa Ana winds and winter rains do the most damage.
Shingle Grade and Heat Performance
Montclair’s inland valley summers push temperatures over 100°F for weeks at a time. That heat cycles through the roof deck daily and shortens the life of budget shingles fast. We spec shingles with UV-resistant granules and work with you on architectural shingles if you want extra heat performance and a deeper shadow line.
New Roof Installation in Montclair
New Roof Installation in Montclair is less common than replacement, because the city is mostly built out with little vacant land left for new construction. When it does happen, it’s typically an addition, a garage conversion, or a full tear-off rebuild after years of deferred maintenance. A new roof installation here runs $11,200 to $18,600 on average, depending on roof size, pitch, and whether we’re working from bare framing or replacing everything down to the rafters.
On a new installation, we have the advantage of starting clean. Proper decking, proper underlayment, proper ventilation, and correct flashing from day one. That means fewer problems ten years down the road than a re-cover over old materials.
We pull permits on new installations and reroofs in Montclair. When the job is done, it’s inspected and signed off. If code upgrades are triggered by the scope of work, we tell you before we start and build the cost into the contract.
Full Tear-Off and Rebuild
When we strip a Montclair roof down to the frame, we’re not just removing shingles. We’re removing decades of patches, old felt, dried-out tar, and sometimes abandoned layers of built-up roofing that were left in place by previous contractors. That material gets hauled and disposed of, and it adds to the job. We don’t bury it in the attic or lay new materials over it.
After the tear-off, we inspect the rafters, replace any damaged framing, and then rebuild the roof system in the right order: decking, underlayment, flashing, ventilation, then the finished surface.
Attic Ventilation and Roof Lifespan
Heat is the silent killer of Montclair roofs. If your attic has gable vents only and no ridge vent or soffit intake, the air inside can hit 140°F or more in July. That cooks shingles from below and dries out underlayment. On a new installation, we address ventilation as part of the roof, not as an optional add-on.
Trusted Brands We Service in Montclair
We don’t lock you into one shingle manufacturer. We work with seven leading brands, including GAF, Atlas, and Tamko, plus CertainTeed, Owens Corning, IKO, and Boral. That means you get the right material for your home and your budget, instead of whatever the roofer’s supply house has a deal on. For Montclair homes with flat or low-slope sections, we can pair a GAF cap sheet with a tapered system to fix ponding. For pitched roofs, Atlas and Tamko architectural shingles hold up well in the valley heat. You choose. We install to manufacturer spec so the warranty stays intact.

AfterCommon Roof Replacement Problems We See in Montclair Homes
- Dried-out built-up roofs ponding at low spots. The felt-and-tar flat sections on older Montclair homes absorb years of sun until the membrane cracks. Water then pools at the low points and leaks after the first heavy winter rain. A quote that only prices shingle squares misses this completely.
- Hidden second and third roof layers concealing rot. Decades of reroofs mean many Montclair decks have never been seen since the house was built. Once we strip the layers, we often find saturated decking and failed underlayment that no one knew was there. That’s why we strip to decking before we commit to a final number.
- Flashing and ridge cap failures from Santa Ana winds. The dry offshore winds that hit the Pomona Valley every fall stress roof edges, pipe boots, and ridge lines. We find lifted flashing and cracked caps on roofs that look fine from the ground.
- Undersized attic ventilation shortening roof life. Many Montclair attics were built with minimal venting. In a climate with weeks of triple-digit heat, that means shingles bake from underneath. We correct the venting during replacement, not after the new roof starts failing.
Pricing for Roof Replacement in Montclair, CA
An asphalt shingle roof replacement in Montclair typically runs $9,800 to $16,400. A full new installation with structural work or significant decking replacement lands between $11,200 and $18,600. Flat and low-slope sections with built-up roofing add cost because of the extra material layers and the labor to strip old felt-and-tar systems.
What moves the price most in Montclair is what’s under the surface. Extra roof layers mean more tear-off and disposal. Rotted decking means plywood replacement. Ponding on flat sections means a tapered re-cover or new crickets. We put all of that in the contract as an allowance, and we don’t spend past it without your written approval. Call (877) 731-1384 to schedule a free estimate. We’ll walk the roof, document the condition, and give you a line-item price.

FAQs About Roof Replacement in Montclair
Because Montclair’s postwar homes often have two or three stacked roof layers hiding rot, failed underlayment, or damaged decking that no one could see from the surface. We write allowances into the contract for exactly this. If we find rotted decking, ponding damage, or framing trouble once the old layers come off, we show you photos, price the added scope in writing, and get your approval before we proceed. Call (877) 731-1384 and we’ll explain how our allowance system works before you sign anything.
Yes. You cannot lay a new built-up or modified bitumen roof over dried-out felt-and-tar and expect it to last. We strip to the decking on flat and low-slope sections, inspect the wood, and then rebuild the system with new membrane, taper where needed, and correct flashing. Skipping the tear-off just means you’ll pay for a new roof that fails early. We’ll scope it properly from the start.
We find the low spot, mark it, and design a tapered system that moves water toward the drains or scuppers. Sometimes that means adding crickets or rebuilding a section of roof structure. Simply re-covering the same low spot with new membrane doesn’t solve the problem, because the water still pools there and eventually finds a seam. We fix the slope, not just the surface. Call (877) 731-1384 for a free inspection if you have standing water after rain.
Yes, if it’s installed with proper attic ventilation. Montclair’s summer highs over 100°F shorten the life of any shingle if the attic can’t exhale heat. We check ridge vent, soffit intake, and existing venting on every replacement and bring it up to current code where needed. The shingles we install from GAF, Atlas, Tamko, and other lines are rated for inland valley climates. The ventilation is what makes them last.
Look at what’s included in the tear-off, whether decking replacement is priced as an allowance or left out entirely, what underlayment is specified, and whether the contractor is pulling a permit. Two quotes for the same Montclair house can look $3,000 apart when one includes stripping multiple layers and one doesn’t mention it. We give you a line-item contract so you can compare apples to apples. Call (877) 731-1384 and we’ll walk you through it.
