CertainTeed Construction in Montclair, CA | Square One Builders
We provide independent CertainTeed roof repair, replacement, and gutter service across Montclair, CA. Our crews know CertainTeed shingles and underlayments behave a specific way under Pomona Valley heat and Santa Ana wind, and that experience shapes every re-roof we take on inside 91763. Call (877) 688-9930 for a free estimate.
Square One Builders is a full-scope General Contractor – Montclair, not a roofing-only shop, so your CertainTeed project sits alongside framing, stucco, windows, and every other system under one accountable team. We are not authorized by, affiliated with, or sponsored by CertainTeed. We simply install and repair their products more often than most contractors in Montclair because CertainTeed is the most widely specified roofing brand on this city’s post-war tract homes.
Why Montclair Residents Choose Us for CertainTeed Service
Most Montclair homes were built between the 1950s and 1970s, and a large share still carry CertainTeed products on the roof. We have torn off, patched, and re-roofed those systems across hundreds of Pomona Valley homes, so we recognize failure patterns before they become interior damage. Brent Calloway, our owner and general contractor, has spent the better part of three decades on Southern California remodels and re-roofs, and the same instinct against wasted material and wasted time carries into how we handle CertainTeed work.
When we repair a CertainTeed roof in Montclair, we match the existing shingle profile where it is still in production. Where a line has been discontinued, we use equivalent-rated architectural shingles or manufacturer-approved accessories instead of forcing a mismatched patch that will fail early and look wrong from the street. We also carry common CertainTeed accessories and underlayment options locally, so a typical Montclair repair does not stall waiting on parts from a distant distributor.
We are a general contractor, which means a re-roof that uncovers rotted fascia, failed gutter runs, or soft decking at a valley does not require you to call a second company. We handle the roof, the gutters, the fascia repair, stucco touch-up, and any framing correction under our single contract. From the ground up, one contractor, every system.

Common CertainTeed Construction Problems We Solve in Montclair
- Granule loss and edge curling on south- and west-facing slopes. Montclair’s 90-plus-degree summer days thermal-cycle Landmark and Presidential asphalt shingles hard. The sun-facing planes shed granules and curl at the edges years before shaded planes show any wear. We see this constantly on 1960s and 1970s tract homes throughout 91763.
- Shingle tabs unsealing after Santa Ana wind events. Wind-driven dust and grit off the San Gabriel foothills abrades the sealant strips on CertainTeed shingles, especially on the windward plane. Tabs lift and catch wind, and the roof starts losing shingles one storm at a time. This shows up on foothill-facing Montclair roofs long before the rest of the field ages.
- Leaks at valleys and penetrations on original 1950s-70s underlayment. Older CertainTeed underlayment and valley flashing reach end of life together. By the time you see a ceiling stain, the shingles may still look serviceable but the water has already found the seams underneath.
- Fascia rot behind sagging or undersized 5″ K-style gutters. Narrow Montclair lots with shallow slab-on-grade foundations channel storm runoff against fascia and gutter runs. When gutters back up, water sits against the fascia board and rots it behind the gutter, which then requires roof-edge and gutter replacement together.
- Partial re-roofs on narrow-lot tract homes with alley access only. Tear-off debris staging, material delivery, and ladder placement get tight on Montclair’s zero-lot-line parcels. We plan the staging at the permit counter before the first shingle comes off, because a blocked alley or encroaching neighbor adds days to a project.
CertainTeed Service in Montclair: What Local Conditions Mean for Your Equipment
Montclair is nearly rectangular and landlocked at about 1.1 square miles, with essentially no vacant land inside 91763. Every CertainTeed roof we touch here is a re-roof on an existing narrow 1950s-70s tract lot, not new construction. That changes how the job runs. On a typical Montclair tear-off, the dump trailer and material drop have to fit an alley that may be shared with three neighbors. Zero-lot-line setbacks mean we often cannot stage debris on the side yard, and the permit counter will ask how we plan to protect the adjacent structure. We work those answers out before we submit, because the alternative is a stop-work order and a roof left open to the Pomona Valley sun.
On a 1960s stucco tract home near Ramona Avenue, we tore off a 20-plus-year Landmark roof whose west-facing plane had curled and shed granules while the shaded north plane still looked serviceable. That is the classic Montclair heat pattern. We re-decked two soft sheathing panels at the valley, laid CertainTeed DiamondDeck underlayment, and installed Landmark architectural shingles with new 5″ K-style gutters and fascia repair, all while staging the job through a narrow alley the lot allowed. That is what CertainTeed service in La Verne and Montclair actually looks like.
CertainTeed Models & Products We Service in Montclair
We install and repair the CertainTeed product lines most common on Montclair’s post-war housing stock. Landmark architectural shingles, including Landmark Pro and Landmark Solaris, cover a large share of the roofs we re-shingle. Presidential Shake and Presidential T/L impact-rated shingles appear on higher-end remodels and homes where homeowners want a heavier profile. We also handle CertainTeed XT and XT 25 synthetic underlayments, DiamondDeck underlayment, vinyl soffit and fascia, and 5″ K-style seamless gutter systems.
Our parts approach is straightforward. Where the original CertainTeed shingle profile is still in production, we match it exactly. Where it is discontinued, we do not patch with whatever is on the shelf. We spec an equivalent-rated architectural shingle that matches the profile and color as closely as the manufacturer allows, then tell you plainly what that means for appearance and longevity before work starts. We spec the right material for your project.

AfterCertainTeed Service Pricing in Montclair
CertainTeed work in Montclair follows the same pricing logic as the surrounding Pomona Valley market. What you pay depends on roof size, pitch, number of planes, access, and whether we are repairing or replacing. Here is what we typically see across 91763:
| Service | Typical Montclair Range |
|---|---|
| Roof Repair | $400 – $1800 |
| Roof Replacement | $8000 – $20000 |
| Gutters & Accessories | $400 – $1800 |
A repair under $1,000 usually involves a small patch, sealant work, or gutter section replacement. A full re-roof on a Montclair tract home typically lands between $8,000 and $20,000 depending on square footage, tear-off layers, decking condition, and whether we are pulling permits for zero-lot-line staging. Our free estimate includes a line-item written quote, so you see exactly what the roof, underlayment, gutters, and any fascia or decking work will cost before you commit. Call (877) 688-9930 to schedule yours.

FAQs – CertainTeed Construction in Montclair
If the roof is approaching 20 years and the west plane is curling with heavy granule loss, repair rarely makes financial sense. You would be paying to patch a roof that will keep failing plane by plane. On Montclair’s tract homes, we usually recommend replacement when the sun-facing slope has widespread curling and the underlayment is the same age as the original shingles. Call (877) 688-9930 and we will inspect it honestly, with no pressure either way.
Yes, and it is the biggest scheduling variable on Montclair jobs. Narrow lots with alley access mean debris staging, material drops, and even ladder placement need to be planned before the tear-off begins. We coordinate with the Montclair permit counter and neighboring properties ahead of time so the roof gets closed back up on schedule. Your remodel, fully managed.
Both lines are rated for the wind loads we see in the Pomona Valley, but the failure mode we watch for is not shingle blow-off. It is sealant-strip abrasion from wind-driven dust and grit. A properly nailed Landmark or Presidential roof with intact sealant strips handles Santa Ana events well. The issue is older roofs where that sealant has already degraded from years of heat cycling.
When the original CertainTeed line is still in production, we match it directly. When it has been discontinued, we use an equivalent-rated architectural shingle that matches the profile and color as closely as the manufacturer allows, then tell you exactly what the patch will look like before we start. We do not force a mismatched shingle onto a roof and call it good. Call (877) 688-9930 for an exact quote on your repair.
Often, yes. On Montclair’s narrow lots, the fascia and 5″ K-style gutters take real punishment from concentrated storm runoff, and rotted fascia is common behind sagging gutters. If the gutters are original to a 1950s-70s home, replacing them during the re-roof saves you a second mobilization and a second round of staging headaches. We assess that as part of every Montclair estimate.
