A tear-off over an occupied apartment building is a different job from a tear-off over a house. People are asleep under it, cars are parked beside it, and the noise starts early.
Most of what goes wrong on these projects is scheduling and communication, not roofing.
Roofing in Alhambra at a glance
A new roof in Alhambra runs $7,500 to $12,000 in asphalt shingle, $12,000 to $18,000 in metal and $15,000 to $25,000 or more in tile. Alhambra runs its own building department, so permits are filed with the city rather than with Los Angeles County.
Occupied buildings and shared roofs
Three things separate a multi-unit roof from a house roof, and each costs money if it surfaces late.
Tenants are underneath. Tear-off is loud, dusty and drops debris. That means written notice, protection over walkways and parked cars, and a start time that does not begin at first light over bedrooms. We sequence by section and put the sequence in the estimate.
Boards need a scope they can vote on. An HOA cannot approve a lump sum delivered verbally. We break the scope by section and by cause, so a board can see what is urgent, what is preventative and what can wait a budget cycle.
Responsibility is shared and often unclear. On a condo roof, who owns the repair between the association and an individual owner is a question that should be settled before anyone starts, not at invoicing. We flag it at the walk.
Low-slope roofs behave differently
Much of Alhambra’s apartment stock has low-slope or flat roof sections rather than pitched ones, and they fail in ways a house roof does not.
Water does not run off, it sits. Any low spot becomes a pond, and standing water finds every seam. Drains and scuppers block with debris and turn a whole roof into a shallow tank, which is both a leak risk and a real structural load.
The seams and the flashings around parapets, drains and mechanical units are where these roofs actually fail. The field of the membrane is usually the last thing to go.
The older single-family stock, mostly 1920s bungalows and Spanish Revival, is a separate problem: steeper pitches, tile or composition over decades of layers, and deep overhangs hiding the rafter tails.
Roofing services we provide in Alhambra
- Low-slope and flat roof repair, seams, parapets and drains
- Occupied-building tear-offs staged by section with tenant notice
- Drain and scupper clearing where ponding has started
- Written scopes formatted for HOA board approval
- Pitched roof replacement on the older single-family stock
Where building exteriors need work alongside, our stucco and exterior crew handles that on the same schedule.
What a roof costs in Alhambra
| Roof type | Typical range |
|---|---|
| Asphalt shingle | $7,500 to $12,000 |
| Metal | $12,000 to $18,000 |
| Tile | $15,000 to $25,000+ |
These are the ranges Modern Builders publishes for a new roof. Estimates depend on size, pitch and materials, and financing is available. For leak diagnosis and repair we do not publish a figure, because a number set from the ground is a number that changes once we are on the roof. You get a written estimate after the inspection.
Multi-unit work carries two costs a house does not. Protection and staging around occupied units takes longer, which shows up as schedule rather than rate. And on a low-slope roof, whether the insulation beneath the membrane is wet decides between a re-cover and a full replacement, which is a large difference.
When a roof repair is the wrong purchase
We will tell you to wait in three situations. If the roof is ponding because the drains are blocked, clearing them first may buy years and costs almost nothing. If the insulation under a low-slope membrane is saturated, a re-cover traps the water and the new roof fails early. And if a board wants a patch to hold until a full project two or three years out, that is sometimes sensible and sometimes not, and we will say which.
How the job runs
On an occupied building the first conversation is sequencing and notice, because that is what makes or breaks the job for the people living there. We check drains, seams and parapet flashings before the field of the roof, and on a low-slope roof we test whether the insulation is wet. The scope comes back split by section and cause, which is the format a board can actually vote on. Walkways are cleared every evening and one crew stays with the building.

| Danny R. Anaheim, CA | “Working with Bryan and his very professional team has been a pleasure to work with. As a commercial General contractor working with a lot of different subcontractors, Modern Builders (Bryan) definitely stands out. Bryan and his team have done quite a few projects for me now, mostly personal projects, roofing (3) projects, 2,500 SF, couple painting projects, love the Cleanness, they put down protection, clean up after themselves and give updates. I really appreciate the drone shots, along with all the permits, specs and pictures sent all in a file for great document control.” | Yelp |

Frequently asked questions
Do you work on apartment buildings and HOA properties?
Yes. We stage tear-offs by section so tenants are not living under an open roof, provide written notice periods, and format the scope by section and cause so a board has something it can approve rather than a single lump figure.
Why does water sit on my apartment roof?
Because it is low-slope and something is stopping it draining, usually a blocked drain or scupper. Standing water finds every seam and adds real weight. Clearing drains is cheap and often the highest-value thing you can do.
Can we just re-cover the existing flat roof?
Only if what is under the membrane is dry. If the insulation is saturated, a re-cover seals the water in and the new roof fails early. That is the single most important thing to establish before choosing between re-cover and replacement.
Who pays, the association or the owner?
That depends on your governing documents, and it is worth settling before work starts rather than at invoicing. We flag where a repair crosses that boundary at the walk.
What does a new roof cost in Alhambra?
Asphalt shingle runs $7,500 to $12,000, metal $12,000 to $18,000 and tile $15,000 to $25,000 or more, depending on size, pitch and materials. Low-slope commercial and multi-family roofs are quoted separately after inspection.

Yes. We find the source of the leak, not just the stain, and repair the Alhambra roof so it holds through the next winter.

Yes. Gutters and roof work go together, and we can handle both on your Alhambra home for a watertight result.

Once a year and after major storms is a good rule. A quick Alhambra inspection catches small issues while they are still cheap to fix.
