Roofing Built to Take the Heat and Hold Through the Storms in Montclair, CA

Kaliber Roofing has spent years on rooftops across Montclair, CA, and the surrounding Inland Empire, where the same cycle repeats. Summer heat bakes shingles and dries out sealants for months, then a handful of concentrated winter storms find every weak spot at once. We handle both halves of that pattern. Our crews install and repair residential and commercial roofs, trace leaks to their real source, replace failing tile underlayment, build flat roof systems, and fit fascia and gutters. We work under CSLB license #1074060, answer calls 24 hours a day, and start every project with a free inspection and a written estimate you can read without a sales pitch.

What We Handle Across Every Roof We Touch

Residential Roofing

Homes lose their weather barrier slowly, then all at once. We install, repair, and replace roofs on single-family houses and townhomes, matching materials to your roof pitch, structure, and neighborhood so the finished result performs and looks right.

Commercial Roofing

Warehouses, retail buildings, and offices need roofs that hold up under foot traffic, rooftop equipment, and ponding water. We build and service low-slope commercial systems on schedules that keep your doors open and your operations running normally.

Roof Inspection

Nobody sees the top of their roof. We walk it, photograph it, and check flashing, penetrations, valleys, underlayment condition, and attic evidence, then hand you a plain description of what is failing, what is fine, and what deserves attention soon.

VIEW MORE

Roof Repair

Not every problem calls for a new roof. Cracked tiles, lifted shingles, split boots, corroded flashing, and open seams all get fixed at the source, so the repair blends into the surrounding roof instead of standing out as a patch.

VIEW MORE

Roof Leak Repair

Water travels before it drips. We follow the stain back uphill to the actual entry point, correct the detail that failed, and verify the fix with testing rather than assuming the first suspicious spot we find was the culprit.

VIEW MORE

Roof Maintenance

Roofs fail from neglected details more often than age. Scheduled visits clear debris, reseal exposed fasteners, correct minor flashing lifts, and document changes over time, which stretches the service life you already paid for and prevents surprise emergencies.

VIEW MORE

Re-Roofing

When a roof reaches the end of its run, we remove the old covering, inspect and repair the deck, and rebuild the system properly. California allows a maximum of two coverings, so we tell you which route your roof qualifies for.

VIEW MORE

Asphalt Shingle Roofing

Shingles remain the practical choice for most homes here. We install architectural and three-tab systems with correct starter courses, ventilation, valley detailing, and code-compliant reflectance, so the roof performs through years of direct Southern California sun.

VIEW MORE

Fascia Installation

The board behind your gutters carries more weight than people realize. We replace rotted, cracked, or pest-damaged fascia, correct the drainage detail that caused the rot, and rehang gutters on sound wood instead of soft, failing material.

VIEW MORE

Tile Roofs

Tile outlives the felt beneath it. We lift and stack tile, replace worn underlayment, swap cracked or slipped pieces, and reset the field so a roof that still looks good from the curb actually stops water again.

VIEW MORE

Flat Roofs

Low-slope roofs punish shortcuts. We install and repair modified bitumen, torch-applied, and single-ply membrane systems, correcting drainage, curbs, and terminations so water leaves the roof instead of standing on it after every storm.

VIEW MORE

Gutters

A roof only works if the water goes somewhere. We install seamless gutters and downspouts sized to your roof area, pitched correctly, and anchored securely, then route discharge away from foundations, walkways, and planting beds.

Commercial & HOA

Managing multiple buildings or a community association? We handle re-roofing, maintenance, and 24-hour emergency response across your entire portfolio, with the phased scheduling and documentation that boards, owners, and property managers actually need.

Your Roof Should Be the Last Thing You Worry About

Everything you own sits under one assembly of wood, membrane, and covering, and it only takes a single failed detail to put water on your ceiling. That is why we inspect carefully, explain what we find without exaggeration, and repair the cause instead of the symptom. Across Montclair, CA, and neighboring communities like Upland, Claremont, and Rancho Cucamonga, our team has built a reputation on showing up when we say we will, doing careful work, and standing behind it.

Frequently Asked Questions


  • Why is my upstairs so much hotter than the rest of the house?

    Usually attic ventilation, not the air conditioning. Trapped heat under the roof deck radiates down through the ceiling all afternoon, and adding balanced intake and exhaust vents often drops upstairs temperatures noticeably without touching the cooling equipment itself.

  • What are the first signs that a roof needs repair?

    Watch for granules collecting in gutters, shingles that curl or lift at the edges, cracked or slipped tiles, rusted flashing around chimneys and vents, and any ceiling stain that darkens after rain. Daylight visible in the attic is urgent.

  • Does a new roof increase home value?

    It rarely returns the full amount at sale, but it removes a major objection and helps a listing move faster. Buyers and inspectors treat an aging roof as leverage, and a documented replacement takes that leverage off the table.

  • What is roof flashing and why does it fail?

    Flashing is the metal that seals joints where a roof meets a wall, chimney, valley, or vent. It fails through corrosion, thermal movement, dried sealant, and incorrect layering, which is why most leaks begin at these transitions rather than in open field areas.
