Call (866) 282-5070

We work throughout Monrovia, from the Craftsman bungalows near Old Town to the foothill lots off Hillcrest Boulevard and the tract neighborhoods south of Huntington Drive. Our team knows what these roofs look like when they come off, and we’ll tell you what yours actually needs, not what’s easiest for us to sell.

Rick Dunnigan leads our crew, and his rule is simple: repair when possible, replace when necessary. That philosophy has kept us honest on hundreds of roofs across the San Gabriel Valley. Call (866) 282-5070 and you’ll get a straight answer, not a sales script.

Why Buena Park Roof Repair Is Monrovia’s Preferred Roof Replacement Company

Monrovia homeowners call us because we don’t show up pushing one brand of shingle and calling it a day. We’re authorized to install and warranty products from seven manufacturers: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. That means when you sit down to choose a material, you’re choosing from a real menu, not whatever happens to be loaded on our truck. “Choose your material, not ours” isn’t a slogan for us, it’s how we bid every job.

We specialize exclusively in roofing: repair, replacement, and inspection. We don’t do gutters, we don’t do siding, and we don’t dabble in general contracting. That focus is exactly why Monrovia homeowners trust us with tear-offs on 1950s ranch homes where the decking condition is anyone’s guess until the old shakes come off. We’ve seen enough of these roofs to quote honestly, not optimistically.

When you call us about a possible replacement in Monrovia, we recommend a Roof Replacement inspection first. It’s a standalone service, no repair commitment required. You get a written condition report. If repair gets you five more years, we’ll say so. If the decking is soft and the shakes are splitting, we’ll show you pictures and explain why.

Serving Monrovia means knowing what these specific houses need. The south-side tracts built in the 1950s and 60s have aged in predictable ways, and we’ve torn off enough of them to know when a roof is salvageable and when it’s done. That local knowledge is built into every estimate we write.

Reroofing in Monrovia

Reroofing in Monrovia usually means tearing off an original wood-shake roof on a mid-century ranch and replacing it with a modern asphalt shingle system. On a typical 1,400 to 1,800 square foot ranch on the south side, expect to pay between $12,600 and $19,800 for architectural shingles, including tear-off, decking repair, underlayment, and new flashing. The final number depends on how much decking has to be replaced once the shakes come off and the crew sees what’s underneath.

What the tear-off usually reveals

On south Monrovia tract homes, the original shakes sit directly on spaced board sheathing that’s had 60 years to trap moisture. When we tear off, we routinely find cracked or soft decking that wasn’t visible from the attic. We include a per-sheet allowance in our quote so you’re not hit with surprise change orders when the condition of the roof finally becomes visible.

Bringing the roof into the modern era

Replacing a Class B or C wood-shake assembly with Class A architectural shingles usually improves the roof’s fire rating, which matters on foothill lots where fire-zone questions come up during permitting. We also add ridge venting where the original roof had none, so the attic doesn’t bake in Monrovia’s summer heat.

Flat Roof Replacement in Monrovia

Flat roof replacement in Monrovia is most common on additions, carports, and mid-century homes that combined a pitched front section with a flat rear section or a patio cover. A typical flat roof section of 300 to 600 square feet runs $5,400 to $10,800 depending on the system, whether it’s modified bitumen, TPO, or a built-up roof with a silicone topcoat. If the flat section ties into pitched shingles, the transition flashing is where we see most failures, and we address that in every flat roof scope.

The roofed patio and carport problem

Monrovia has plenty of homes where a pitched roof over the main house drains onto a flat section over a patio or a carport. Those flat sections don’t slope enough for Monrovia’s occasional heavy winter rains, so ponding water soaks into the seams and rots the plywood beneath. A correct replacement means pulling the old membrane, checking the decking, and setting a slope or a new drain path before laying down the new system.

When the flat roof is the whole roof

Some Monrovia homes, particularly certain 1960s designs, have a fully flat roof with a parapet wall and internal drains. The failure points are always the same: the parapet flashing, the drain collars, and the seams where the membrane was patched over the years. We replace the membrane, rebuild the flashing, and lay a topcoat rated for the San Gabriel Valley’s ultraviolet exposure. Expect $9,000 to $15,000 for a full 800 to 1,200 square foot flat roof replacement.

Trusted Brands We Service in Monrovia

We’re authorized to install and warranty Owens Corning, IKO, and Atlas products, among the seven manufacturers we work with. That matters in Monrovia because so many homeowners are replacing original wood shakes and want to see actual color and profile options before committing. We bring sample boards to your door, not a catalog link. For partial replacements where only one slope needs work, our multi-brand knowledge means we can match the existing shingle more accurately, whether it’s a discontinued Atlas color or a certain architectural profile from Owens Corning. Preserving the visual continuity of your roofline is part of the job, not an upsell.

Common Roof Replacement Problems We See in Monrovia Homes

• Brittle, splitting wood shakes on 1950s and 60s south-side tract homes. A century of Monrovia’s 100-degree summer afternoons followed by cool nights causes thermal splitting. By the time homeowners call us, the shakes are cracking in broad bands and the roof is beyond repair.
• Missing or damaged bird stops on foothill-area roofs. Birds and squirrels get under the shakes at the eave line and nest in the roof cavity. Homeowners call us thinking they have a flashing leak, and the real cause is wildlife intrusion through split or missing bird stops.
• Detached garages, shops, and ADUs left out of the scope. Many Monrovia acreage properties have a main house roof plus separate structures, each with their own valleys, penetrations, and drainage problems. A quote that only covers the house leaves the shop or ADU leaking.
• Santa Ana wind damage to old roof edges. Monrovia sits at the base of the San Gabriel Mountains, and strong Santa Ana events lift the edges of older shingles and shake courses. Once the edge lifts, wind gets underneath and peels the roof back in sheets.
