Monrovia was founded in 1886, and Old Town Monrovia along Myrtle Avenue keeps many of the Craftsman bungalows from that early era. Their low-pitched gables, wide eaves and exposed rafter tails make a re-roof more delicate than on a plain tract house. Higher up, streets end at the Angeles National Forest, and the roofs on them are a fire question.
The trip begins on Pacific Coast Highway in Torrance and covers 42 miles in about 80 minutes. A call beforehand lets us confirm when we can be there. Same day or next day service is on offer as the schedule permits.
A visit to a Craftsman house or a foothill lot
Wide eaves and exposed rafter tails are the first things we protect. Rot in the tails and fascia is something we look for before covering them, and we ask where a truck and ladder can stand without harming a front porch or garden. On foothill streets we ask about steep drives and gates. No charge applies to estimates or roof inspections, and the photos from the roof and attic are shown to you.

What age does to a low-pitched Craftsman roof
Low slopes drain slowly, so flashing at valleys, chimneys and porch tie-ins is where water finds a way in. Old repairs may stack up. Building code sets a minimum slope for some materials, and below it the roof needs a different system. Matching existing shingles matters on a street where houses are close to original, so we bring samples. How we weigh the choice is in our repair or replace guide, and a repair is what we recommend whenever one will hold.
Low slopes, brick chimneys and decades of patches
Most Old Town bungalows were built early in the twentieth century, and the city incorporated in 1887, so roofs here are often on their third or fourth covering. Low slopes drain slowly and punish tired flashing. Brick chimneys are common, and the flashing around them is a frequent source of attic stains. Porch roofs tie into the main roof at joints that old repairs have often smeared with sealant. A thorough inspection covers the roof, the attic and the eave line, and the photos show where earlier patches stopped working. Wide overhangs mean rafter tails need protecting from the tear-off, and soft ones are flagged before they are covered.
Monrovia roof services
Roof Replacement
Craftsman bungalows need a re-roof that respects wide eaves and exposed rafter tails, and foothill lots may need a fire-rated assembly, so Monrovia jobs vary street by street.
Roofing Contractor in Torrance
Our Torrance homepage explains how we schedule estimates for the foothills of the San Gabriel Valley, 42 miles out, and why a call about timing comes first.
Roof Repair
Low-pitched roofs on older bungalows leak at flashing and valleys, which a repair can often fix without touching the rest of a historic roofline.
Skylights
Attic rooms and dormers in Craftsman homes sometimes have skylights whose old flashing leaks around the curb, a detail we check from both roof and attic.
Chimney Flashing & Sealing
Brick fireplaces are a Craftsman signature, and the flashing where chimney meets roof is the most common leak point on Old Town bungalows.
Class A Fire-Rated Roofing
Streets near Monrovia Canyon Park and the forest edge sit close to land the 2020 Bobcat Fire burned, so a Class A assembly is worth pricing at replacement time.
Older Home Roof Replacement
Houses from the 1900s to the 1950s can have plank decking, several layers and rot at the rafter tails that only appear once the old roof is stripped.
Fascia, Soffit & Roof Trim
Exposed rafter tails and wide eaves make fascia and trim part of the look of an Old Town home, and rot behind failing gutters is worth repairing before it spreads.
Myrtle Avenue, Monrovia Canyon Park and parking on narrow streets
Myrtle Avenue is Old Town's main street, and many bungalow blocks around it have narrow lots, mature trees and street parking only. Monrovia Canyon Park sits at the north end of the city, with the steepest, brushiest lots below it. We ask early where a truck and ladder can stand without crowding a porch or garden.
Foothill fire exposure and the Monrovia permit office
Streets nearest the forest sit close to mapped fire hazard zones, and the Bobcat Fire burned in the mountains above Monrovia in 2020. Where fire-rated roofing rules apply is decided by Cal Fire's maps, and with the City of Monrovia we deal with the permit side of a re-roof. Confirm your address. The Los Angeles County service area page shows where rules differ around the county.

Roofing questions from Monrovia
How do you protect Craftsman details when re-roofing an Old Town Monrovia bungalow?
We plan around them. Exposed rafter tails, wide eaves and decorative brackets are protected from the tear-off, and we flag any rotted wood before it is covered. Samples come with us, and we match existing shingles as closely as we can. Some historic properties have design rules, so confirm with the city before you choose a material.
Do Monrovia foothill streets need a fire-rated roof?
Often, near the forest edge. In mapped high-hazard zones building code generally requires a fire-rated roof, a point that matters after the 2020 Bobcat Fire burned in the San Gabriel Mountains above Monrovia. The city or Cal Fire can tell you how your address is mapped. See Class A fire-rated roofing for the options.
Are brick chimneys on Monrovia Craftsman homes a common leak point?
Yes. Many early 1900s bungalows have brick fireplaces, and the flashing where chimney meets roof dries out, cracks or pulls away over a century of seasons. Water then runs down the masonry into the attic. A repair is often enough when the brick is sound. See our chimney flashing and sealing page and chimney flashing leak guide.
