A full roof replacement in Pomona typically costs between $9,500 and $22,000 for a standard single-family home, with most asphalt shingle jobs landing around $12,000 to $16,000. Flat or low-slope roofs, common on older Pomona homes and commercial buildings, run higher per square foot due to membrane and drainage work. We know Pomona’s housing stock because we work on it every week, from Craftsman bungalows near downtown to 1950s ranch homes in Phillips Ranch.

- We stock GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral so your roof gets the right material, not the one we happen to sell.

Why Pomona Homeowners Choose Millstone Roofing
Pomona homeowners deal with a specific set of roof problems that roofers from outside the area often miss. Our Roof Replacement team has torn off and rebuilt roofs on Lincoln Park ranches, Wilton Heights bungalows, and acreage properties near Phillips Ranch with detached shops and ADUs. Nelson Ibarra leads every project personally, and he walks each roof before we quote it. No sales rep guesswork.
We work with seven roofing manufacturers, not one. That means when we tell you a CertainTeed Landmark shingle fits your home better than an IKO Nordic, it’s because of your roof’s slope, exposure, and budget. Not because of a supplier quota. Homeowners in Pomona keep calling us back because we give straight answers: repair when repair is right, replace when replacement makes sense.
Estimates are free, written, and line-itemed. You’ll know exactly what the tear-off costs, what the decking looks like once we open it, and what the material and labor totals are before you sign anything. Call (855) 341-6021 to schedule your inspection.
Roof Installation in Pomona
Roof installation in Pomona means a complete tear-off of the existing roof system down to the sheathing, a deck inspection, and a new roofing assembly built from the deck up. On most Pomona homes we’re removing one or two layers of old shingles, sometimes original 1950s three-tab over wood plank decking. We replace rotted or water-damaged decking sections before anything new goes on.
Full Tear-Off and Decking Replacement
On older Pomona homes, the decking is often the quiet failure. Original plywood or spaced plank sheathing from the 1950s and 60s has usually softened around penetrations and along eaves. We scope re-decking into the square count before quoting, not after tear-off begins. A full re-deck on a 1,500-square-foot ranch runs $2,800 to $5,500 in Pomona, depending on what we find.
Architectural Shingle Systems
Most Pomona homeowners choose architectural shingles for their wind resistance and lifespan. A standard architectural shingle roof in Pomona runs $12,000 to $18,000 installed. We install every layer correctly: starter strip, underlayment, valley flashing, ridge vent, and proper nail pattern. Wind rating is not a sticker. It’s a system, and Santa Ana gusts test it every fall.
Roof Replacement Contractor in Pomona
A roof replacement contractor in Pomona has to handle two very different roof types in the same service area: steep-slope residential shingle roofs and low-slope flat or membrane systems on mid-century homes, patio additions, and commercial buildings. We do both. That dual specialization is less common than you’d think, and it matters when your Pomona property has a pitched house and a flat-roofed shop or patio on the same parcel.
Pitched Residential Roof Replacement
Most of our Pomona residential work is full tear-off and replacement with architectural shingles from GAF, CertainTeed, or Owens Corning. We re-run all flashing, replace pipe collars, and install ridge venting matched to the home’s ventilation setup. A typical Pomona single-family replacement takes three to five working days from tear-off to final inspection.
Flat and Low-Slope Systems
Flat roofs in Pomona fail differently than pitched roofs. Ponding water after winter rains softens the deck, and UV exposure accelerates membrane cracking. On a Pomona flat roof replacement, we address slope and drainage during scoping, not as a change order after we open the roof. Built-up and modified bitumen systems run $11 to $16 per square foot installed in Pomona, with single-ply options like TPO or PVC on the higher end.
Trusted Brands We Service in Pomona
We install and stand behind systems from seven manufacturers: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. For Pomona homeowners, that broad portfolio matters more than in most cities. The Santa Ana wind exposure here pushes us toward shingles with strong wind warranties, like CertainTeed’s Landmark series or Owens Corning Duration with their reinforced nail strip. We keep local stock of common colors and profiles, so material lead times for Pomona projects stay short. Your roof, your choice. The right material for your roof, not the easiest one for us to stock.

AfterCommon Roof Replacement Problems We See in Pomona Homes
- Curled and torn three-tab shingles on 1950s ranch homes. The original shingles on Phillips Ranch and Ganesha Park ranches are often 25 years old or more. After a fall Santa Ana event, we see edges curled back and shingles lifted clean off the deck. Repair on those roofs is a band-aid. Replacement is the honest answer.
- Ponding on flat patio additions and low-slope sections. Many Pomona homes have patio or bonus-room additions with nearly flat roofs. Water sits after the first winter storm, and by the time the homeowner sees the ceiling stain, the decking underneath is already soft.
- Original wood sheathing that has failed around penetrations. On pre-1960 Pomona homes, the areas around plumbing vents, chimneys, and skylights are almost always the first to rot. We scope re-decking into these zones before quoting, so the price doesn’t move once we open the roof.
- Long material hauls and tight access on acreage properties. Pomona’s larger parcels, especially around Phillips Ranch, often have detached shops, ADUs, or equipment buildings. Shingle squares, dumpsters, and staging have to be planned by load and access route. We budget that up front, not as a surprise line item.
Pricing for Roof Replacement in Pomona, CA
A standard asphalt shingle roof replacement on a Pomona single-family home runs between $9,500 and $18,000, with larger or steeper homes pushing toward $22,000. Here’s what moves the number: square footage, roof pitch, number of layers we’re tearing off, how much decking needs replacement, and whether there are flat sections that require membrane work. A full tear-off with architectural shingles on a 1,800-square-foot ranch in Pomona typically lands between $13,000 and $17,000. Flat roof sections add $11 to $16 per square foot.

FAQs About Roof Replacement in Pomona
Yes. Acreage properties in Pomona change the quote in three ways: outbuilding square footage gets added to the total scope, equipment access and material staging get planned by route rather than assumed as curb drop, and flat or low-slope sections on shops or ADUs get priced separately from the pitched house roof. We walk the entire property during the inspection and build the quote from what’s actually there, not from a satellite image. Call (855) 341-6021 to schedule that walk-through.
We settle the drainage and slope plan during scoping, before the quote goes out. On Pomona open-lot properties, a low-slope patio addition or detached unit often has ponding that only shows after the first winter rain. We identify the low points, decide whether tapered insulation or a re-slope is needed, and price it into the flat roof line item. That way the drainage fix is part of the original contract, not a change order after tear-off begins. Call (855) 341-6021 to get a written quote that includes the drainage plan.
Because original three-tab shingles on 1950s ranch homes in neighborhoods like Wilton Heights and Lincoln Park are often decades past their service life. The UV from Pomona’s 100-degree summers bakes the asphalt, and when Santa Ana winds hit in the fall, the brittle edges curl and tear. Once that starts happening, repair is not a real fix. The roof has reached the end of its life. We recommend a full replacement with architectural shingles installed with proper nailing and starter strip for wind uplift. Call (855) 341-6021 for an inspection and honest recommendation.
Yes. We replace steep-slope shingle roofs and low-slope flat membrane systems, which is a rarer dual specialization than what you’ll find in neighboring cities like Claremont or La Verne. Pomona’s mix of single-family homes and flat-roofed commercial and industrial buildings means one contractor can handle both on a single property. If your Pomona parcel has a pitched house and a flat-roofed shop, we scope and price both in the same quote. Call (855) 341-6021 to schedule the inspection.
Wind rating is only as good as the installation. We use the manufacturer’s required nail pattern, a proper starter strip, and the correct number of fasteners per shingle, all documented during installation. We also verify decking is solid enough to hold the fasteners. On one ranch property off the Phillips Ranch area, our crew replaced original three-tab shingles that had curled and torn after a Santa Ana wind event, then installed architectural shingles with a proper starter strip and ridge vent for wind uplift. That’s the standard, not the exception. Call (855) 341-6021 to talk about what wind-rated system fits your Pomona home.
