Fast, Reliable Roof Replacement Across Monrovia
A full Roof Replacement in Monrovia typically runs $12,000 – $28,000 for a standard single-family home, with architectural asphalt shingles landing most jobs between $14,000 and $22,000 depending on tear-off depth, decking condition, and whether the home sits in the wildland interface above Foothill Blvd. We know these foothill lots, the 1900s – 1940s bungalow stock, and the tree-shaded canopies that turn a simple re-roof into a decking and dry-rot job the moment the first layer comes off. If your roof is on its second or third layer, or you’re seeing moss creep at the valleys, call (833) 589-7971 for a site inspection and written estimate. We serve all of Monrovia, including the Old Town historic district, the foothill neighborhoods above Hillcrest, and the tract homes below Foothill Blvd. in 91016 and 91017.
Why Hollywood Roofing Co Is Monrovia’s Preferred Roof Replacement Company
Monrovia homeowners keep our number because we actually understand what their roofs are up against. The houses here aren’t generic California stucco boxes. The 1920s Craftsman bungalows near Old Town sit on steep, tree-shaded lots where a third tear-off layer hides rotted skip-sheathing underneath. The 1950s – 1980s tract homes and hillside estates above Foothill often have composition roofs that Santa Ana winds have baked brittle. We’ve re-decked enough solid board and spaced sheathing across Monrovia to know what a given street is likely to expose before we write the estimate.
Roland Vega, our owner, built Hollywood Roofing Co around a simple idea: inspect honestly, price honestly, and do the work so it stays done. That’s why we carry all seven major roofing brands – GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral – so the recommendation comes from what your house actually needs, not what a supplier rep wants moved this quarter. We’ve replaced roofs throughout 91016 and 91017, from Bradbury-adjacent hillside estates down to the flat-lot homes near Duarte Road, and our estimates account for what Monrovia’s building conditions actually require.
Styles & brands we work with






Roof Replacement Contractor in Monrovia
A Roof Replacement Contractor in Monrovia does more than swap shingles. The job means tearing off every existing layer, evaluating what’s underneath, repairing or re-decking the substrate, and installing a roof system that handles this city’s specific conditions: intense summer UV, Santa Ana wind gusts off the foothills, winter rain pooling in shaded valleys, and constant debris from live oaks and deodar cedars. On most Monrovia homes, we replace the underlayment, flashings, vents, and drip edges too, because that’s where the rot hides. A full Monrovia re-roof typically takes 3 – 7 working days from tear-off to final inspection, plus any time required for a preservation review if the home sits in a designated historic district.
Full Decking and Substrate Assessment
Every Monrovia tear-off starts with a substrate evaluation once the old layers are gone. On 1900s – 1940s bungalows, that often means exposed spaced board decking that’s sagged between rafters. We write a decking allowance into every contract, so when the sheathing is rotted or the spacing won’t support modern code, the re-deck is priced and approved in writing before we open the next square.
Permits and Historic District Compliance
Monrovia re-roofs fall under city permit requirements, and homes near Old Town that are visible from the street may trigger a preservation review. We handle the permit application, coordinate any needed review, and keep the job moving while the city does its work. It’s another reason to hire a contractor who’s actually pulled permits in Monrovia before.
Asphalt Shingle Roof Replacement in Monrovia
An Asphalt Shingle Roof Replacement in Monrovia is the most common job we do, and for good reason. Architectural shingles – the dimensional ones that hold up better in wind and heat – dominate the foothill and canyon-facing lots. A new architectural shingle roof in Monrovia runs $14,000 – $22,000 on a typical 1,800 – 2,400 square foot home, with tear-off of old layers adding $3,000 – $6,000 when there are two or three existing roofs to pull. In the flatter neighborhoods below Foothill Blvd. and out toward Mayflower Village, simpler roofs on newer tract homes sometimes land at the lower end, closer to $12,000 – $16,000, when the decking is sound and only one layer needs removing.
Wind-Rated Installation on Foothill Lots
Homes on the exposed ridgelines above Hillcrest and along Canyon Blvd. take the brunt of Santa Ana winds. We install architectural shingles with the manufacturer’s high-wind starter strip, six-nail fastening, and proper ridge venting so the edges don’t peel when the gusts hit 60 mph in October.
Fire-Resistant Roofing for the Wildland Interface
Monrovia’s hillside zone – generally the area north of Foothill Blvd. into the San Gabriel foothills – is in a designated wildland-urban interface. Re-roofing here may require fire-rated assembly, including specific underlayment, Class A shingles, and upgraded drip edges. We factor that into the estimate before we start, so the final number doesn’t surprise you at permit time.
Trusted Brands We Service in Monrovia
We install GAF, CertainTeed, and Tamko most often on Monrovia homes. GAF and CertainTeed carry the premium architectural lines that foothill homeowners want for wind and UV resistance. Tamko brings solid value for budget-conscious replacements below Foothill, where the exposure is less severe. Owens Corning service in Monrovia, IKO, Atlas, and Boral round out the full seven-brand line, which means when we recommend a material, it’s matched to your roof’s pitch, exposure, and budget – not to a brand we’re locked into. Seven leading brands. One honest recommendation. That’s the entire point of carrying them all.

AfterCommon Roof Replacement Problems We See in Monrovia Homes
- Third-layer tear-offs hiding rotted decking: Old Town and foothill bungalows often have three layers of composition piled up. Pull them off, and the spaced board decking underneath is sagged, rotted, or both – work that was never in the original bid.
- Moss and dry-rot on shaded north-facing slopes: Live oaks and deodar cedars hold moisture against the roof all winter. By the time the shingles look bad, the sheathing at valleys and penetrations is usually worse.
- Santa Ana damage on exposed ridges: UV and wind age asphalt shingles fast on the ridgelines above central Monrovia. Granule loss, lifted tabs, and cracked sealant strips are common by year 15 – 18 even on quality architectural shingles.
- Historic district compliance: Homes near Old Town that are visible from the street can require preservation review before any work starts. We handle that paperwork and keep the job timeline honest around it.
Pricing for Roof Replacement in Monrovia, CA
Here’s what we tell Monrovia homeowners, straight. A full tear-off and architectural shingle re-roof on a standard foothill bungalow runs $14,000 – $22,000. Add $3,000 – $6,000 when you’re pulling multiple existing layers. Add $4,000 – $8,000 if the decking needs substantial re-sheathing, which happens often on 1900s – 1940s homes above Foothill.

FAQs About Roof Replacement in Monrovia
Because older Monrovia homes, especially the 1900s – 1940s bungalows in the foothill blocks above Old Town, frequently have rotted or sagging decking hidden under existing layers. When we pull old composition off, we often find spaced board sheathing that isn’t solid enough for modern underlayment. We write a decking allowance into the contract upfront, and if we find damage, you get a written change order and approve it before we proceed. That’s how we avoid the quote jumping without your knowledge. Call (833) 589-7971 and we’ll explain exactly how the allowance works on your specific home.
Yes, often. Monrovia properties within the historic district, or visible from designated historic corridors, may trigger a preservation review for street-facing roof work. The review typically focuses on matching the existing roof profile and material appearance. We prepare the paperwork, submit the application, and coordinate with the city’s review process so your re-roof doesn’t stall. We’ve done this on multiple Craftsman-era homes in the Old Town blocks, and the review usually adds a week or two, not months.
Compare them line by line against the same scope. Does the bid include tear-off of all existing layers, or just the top one? Is decking repair included, or listed as a TBD allowance? Does it specify the exact shingle brand and line, underlayment type, ventilation upgrades, and permit fees? In Monrovia, the two biggest line-item gaps we see are decking allowances and wildland-interface fire-rated upgrades. A bid that’s $5,000 cheaper often has those items missing entirely. Get each bid broken out by line item, then call us at (833) 589-7971 and we’ll review a competitor’s bid against ours, honestly.
The live oaks and deodar cedars above foothill homes in Monrovia drop constant debris – needles, acorns, branches – and shade the roof enough that moss and lichen take hold on north-facing slopes. That moss works its way under flashing at chimneys, valleys, and pipe penetrations, and the sheathing beneath rots long before the shingle surface looks failed. We inspect tree damage during every Monrovia roof inspection and factor debris maintenance into our long-term recommendations.
Yes, when installed with the right fastening and starter strip, most architectural shingles are rated to 110 – 130 mph wind uplift, which covers what Monrovia sees during Santa Ana events. The key is six-nail fastening on steep pitches, proper edge and ridge detailing, and a starter strip rated for high-wind zones. We install to those standards on every foothill-exposed home above Foothill Blvd., because we’ve seen what happens when a shortcut installer doesn’t. Call (833) 589-7971 to schedule your estimate and we’ll walk your roof’s specific exposure before pricing anything.
If your roof is aging, layered, or showing moss at the valleys, call Hollywood Roofing Co at (833) 589-7971. We’ll inspect it, explain exactly what a replacement would require in Monrovia, and put a written, line-item estimate in your hands. Free estimates, no pressure, and a brand-matched material recommendation that actually fits your house.
