The neighborhoods between Myrtle Avenue and the foothills north of Foothill Blvd see roof conditions that flat-basin cities never deal with. We know what those wind events do to ridge caps on Norumbega Drive and what decades of damp canyon air does to decking in the 91016 zip code. That local knowledge changes how we quote, how we spec materials, and how we protect your home once the old roof is off.

Key Takeaways

• Most Monrovia roof replacements cost $12,000 – $28,000 depending on size, material, and what we find once the old roof is open.
• We inspect first and recommend second. Repair or replace, we’ll tell you which one actually makes sense.
• Santa Ana wind uplift and failed underlayment are the two most common replacement triggers we see across Monrovia.
• Seven brands. One contractor. GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral.

Why Huntington Beach Roofers Is Monrovia’s Preferred Roof Replacement Company

Monrovia homeowners hire us because we carry material options most roofers can’t offer. When a roofer only installs one brand, you get what they have on the truck. When we walk a roof on Lemon Avenue or in the historic district off Myrtle, we can match the material to the roof, not the other way around. That’s why a Craftsman bungalow gets GAF architectural shingles that hold a preservation-sensitive profile, while a mid-century ranch on a flat lot might get a TPO system that handles standing water differently. The recommendation follows the roof’s needs and your budget, not our inventory limits.

We also handle all three stages of roofing under one contractor relationship: Roof Replacement, repair, and inspection. That matters more than homeowners realize. When an inspection is done by one company, the repair by another, and the replacement by a third, nobody owns the full picture. Water intrusion gets blamed on the last guy. Material failures go undocumented. With us, the same team that documented your decking condition during the inspection is the team laying the new shingles. Single point of contact from the first inspection to the final inspection.

Neil Stratton leads our crews, and his approach is simple: we inspect first, recommend second. That’s why we offer standalone roof inspections in Monrovia, not just as a sales tool, but as an honest condition report. If your roof has five more years, we’ll tell you. If it needs replacement before the next Santa Ana season, we’ll show you photos and let you decide. No fear-selling, no manufactured urgency.

Flat Roof Replacement in Monrovia

Flat Roof Replacement in Monrovia is a different animal than pitched-roof work, and we treat it that way. Many Monrovia homes, especially mid-century ranch homes and multi-family buildings along Huntington Drive, have low-slope or flat sections over additions, garages, and carports. A flat roof replacement in the 91017 zip code typically runs $9,000 – $18,000 depending on square footage, membrane choice, and whether we need to replace the tapered insulation beneath. Monrovia’s hot, dry summers bake flat-roof membranes until they crack at the seams, and when winter rain does come, water pools wherever the slope has settled wrong.

We carry TPO, PVC, and modified bitumen systems, so we’re not locked into one flat-roof answer. The right membrane depends on the roof’s exposure, the building’s use, and whether you’re dealing with a homeowner’s association or city permit requirements.

TPO and PVC Membrane Replacement

TPO is the workhorse for Monrovia flat roofs. It reflects heat well, which matters when August temps sit in the high 90s for weeks. PVC costs more but handles standing water better, which makes it the better call for older ranch homes where the roof slope has settled below modern drainage standards. We measure actual slope, document drainage patterns, and recommend the membrane that won’t fight the building’s existing conditions.

Decking and Tapered Insulation Work

Flat roofs hide their damage. Soft decking under a flat membrane often doesn’t show itself until we cut into it. That’s why we write a decking-repair allowance into every flat roof replacement contract before we start. If we find rot, you get a written price for the repair before we proceed. No surprise line items after the roof is open.

Roof Installation in Monrovia

Roof Installation in Monrovia means starting clean, whether it’s new construction in the foothill tracts north of Foothill Blvd or a tear-off on a 1912 bungalow in Old Town. A full new roof installation in the 91016 zip code typically runs $13,000 – $30,000 for architectural asphalt shingles, with the higher end covering complex roof geometry, steep pitches, and historic-district material requirements. The installation itself follows the same sequence every time: decking inspection, underlayment, ice and water shield in valleys and eaves, then shingles nailed to manufacturer spec. What changes is how much repair the decking needs before we can lay the first square.

We install materials from seven manufacturers, which means new construction builders and homeowners alike get brand documentation their lenders and insurers recognize. For Monrovia homeowners replacing a roof, that documentation matters when you sell the home or file a claim.

New Construction Roofing

New construction in Monrovia’s foothill developments needs a roofing contractor who can coordinate with general contractors, hit inspection schedules, and provide the manufacturer paperwork lenders ask for. We handle the full cycle: decking, underlayment, flashing, and shingles or membrane, with the brand documentation attached to the final invoice.

Full Tear-Off and Reroof

Most Monrovia replacements are tear-offs. The old shingles come off, the decking gets inspected and repaired as needed, and the new system goes on. We never roof over old shingles. Layering hides decking rot and adds weight the framing wasn’t designed to carry. A clean tear-off lets us document what’s underneath, which is the only honest way to know what your replacement will actually cost.

Trusted Brands We Service in Monrovia

We’re authorized to install roofing products from GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. That’s seven brands spanning entry-level shingles to premium warranted systems. For Monrovia homeowners, this matters in concrete ways. If you want a specific brand your insurance adjuster specified, we can install it. If one manufacturer is backordered, we’ve got alternatives immediately available with no single-vendor dependency. We also stock common components locally for Monrovia jobs, which keeps material runs short and turnaround faster when we’re matching a specific shingle color on a repair. Manufacturer warranties are available and vary by product line. We’ll walk you through what each brand actually covers before you sign anything.

Common Roof Replacement Problems We See in Monrovia Homes

• Santa Ana wind uplift on foothill streets. North of Foothill Blvd, where the San Gabriel Mountain corridor funnels wind down the canyons, ridge caps and hip shingles peel off in a single event. When we tear off those roofs, we often find the original nailing pattern wasn’t to spec, and the caps were sealed with tar instead of proper adhesive.
• Failed underlayment on decades-old roofs. Many Monrovia homes still carry original felt from the 1980s or earlier. It looks fine from the ground, but it’s brittle and cracked. The first winter rain that gets past the shingles soaks the decking, and the homeowner sees water on the ceiling while the shingles still look intact.
• Soft decking along valleys and eaves. On a Craftsman bungalow in Old Town off Myrtle, our crew pulled the original wood shingle and found the decking soft along the valleys, with only a thin felt underlayment left where the ice and water shield should have been. That’s typical. We documented the sheathing on camera, wrote a decking-repair allowance into the contract before the tear-off, and priced the wood replacement for written approval before we laid a single square of GAF architectural shingles. The homeowner never got a surprise line item after the roof was open.
• Fragile original materials in Old Town. Original wood shingle and clay tile roofs in the historic district need replacement materials that satisfy preservation requirements. That means specific profiles, specific colors, and flashing details that differ from what you’d put on a 1970s ranch home three blocks away. We navigate that approval process as part of the job.
