Flat Roof Replacement in San Bernardino from $2.50. Low slope over additions, patio covers and carports -- the strictest cool-roof rule of all. Free inspection and a written quote.
The multi-family share is what makes San Bernardino low slope different. Two to eight unit buildings with flat roofs and assigned parking are the common job, and on those the constraint is never the membrane -- it is staging, resident notice and where the dumpster is allowed to sit.
Most low slope here is residential: rear additions, converted garages, carport roofs and patio covers tied into the main house. All of it sheds water slowly, so it depends on the drainage rather than on gravity.



If the substrate is sound and dry, a coating at $2.50 to $6.50 per square foot is often the right answer. What is not optional is the rating: low slope needs aged SRI 75 or better in every California climate zone, which is a much higher bar than the steep-slope 16 that applies to the rest of your roof. No standard rate applies across a city with this range of building ages. The two questions that set the price are the deck and the layer count, and both take a minute to answer once somebody is actually up there.
A sound, dry substrate can be coated. Coating a wet one seals the moisture in and buys about a year, so we establish which you have before quoting either.
Fall that has to be rebuilt rather than re-covered, wet insulation, new or enlarged outlets, and long spans where deflection has taken the fall away.
Steep slope needs aged SRI 16. Low slope needs aged SRI 75. They are not interchangeable and a quote that cites one for the other has not read the code.
The range of building ages is what makes San Bernardino different: two houses a mile apart can be sixty years and two coverings removed from each other. That means no standard rate applies, and it means the first question is always the deck rather than the covering. Permits are City of San Bernardino, not the county.
This is a replacement company saying so. In this climate the most expensive mistake is buying the whole roof when the job was the felt underneath it.
A tile roof quoted at $26,000 to $52,000 is very often a $7,000 to $19,000 lift and relay, because concrete outlives felt by decades and zone 10 heat widens that gap further. Somebody has to count your tile before that question can be answered.
If the complaint is an unbearable upstairs rather than a leak, attic insulation and ventilation will usually do more than a new covering -- and it happens to exempt you from the cool-roof requirement as well.
We will say so when it is, and it is the same piece of advice as the opposite one: worth nothing unless you are shown what it rests on.
No standard square-foot rate means anything here.
With a century of building ages in one city, whether an exception applies varies house by house rather than street by street.
The spread of building ages means the breakage allowance should vary too, and on a quote it usually does not.
Two houses a mile apart can need completely different answers here, and the deciding factor is usually how many layers are already up there.
On a multi-building site partial means by building rather than by slope: worst roof first, the rest scheduled.
Zone 10. The cool-roof rule applies to your pitched roof.
Newest subdivisions, busiest geometry, plywood decks.
Its own city, its own building department.
Unincorporated. County permits, and more than one roof.
The oldest stock here. Check the deck first.
Semi-rural, unincorporated, outbuildings everywhere.
Canyon country. Brush interface and county permits.
The questions that come up, before you have to ask.
More urgent here than on the coast. Water still sitting 48 hours after rain means the fall is wrong or a drain is blocked -- and standing water plus zone 10 sun degrades a membrane far faster than either alone.
Because low slope faces the sun directly all day and the code reflects that. Steep slope needs aged SRI 16; low slope needs aged SRI 75, in every California climate zone with no exemption. They are different numbers for different geometry, and quotes confuse them constantly.
Because warranties are written for an average American climate and zone 10 is not one. Sustained heat and ultraviolet take the plasticiser out of asphalt and the life out of felt under tile far faster here than on the coast. Judge a roof by its condition rather than its paperwork.
Usually by about half. A lift and relay is $7,000 to $19,000 against $26,000 to $52,000 for a full tile replacement, because the expensive part of a tile roof is the tile and you already own it. Most Inland Empire tile is concrete in profiles still manufactured, so breakage can be matched.
Typically $9,000 to $22,000. The Inland Empire sits below the Los Angeles basin on labor and above the High Desert, so an LA average reads high here and a national average reads low. Composition runs about $6 to $9.50 per square foot, tile considerably more.
