Your Local Roofer
in Fontana

Fontana is one of the fastest-growing cities in the IE, and with that growth comes a lot of roofing work, new installs, replacements on aging homes, and repairs after wind events. GAX Roofing serves homeowners across Fontana including areas near Sierra Lakes, Citrus Heights, and south Fontana.

One advantage for Fontana homeowners replacing a tile roof: Eagle Roofing Products has a showroom in Rialto, right next to Fontana. Eagle makes some of the best concrete tile available, and their showroom lets you see and handle actual profiles and colors before committing to anything. When we do a tile replacement in this area, Eagle is one of the brands we use most, being able to walk in and pick your material in person makes the whole process a lot easier.

We're a family-owned C39 licensed roofing contractor based in Rancho Cucamonga. Our team handles every estimate and project-manages every job from start to finish. You always have a direct line to us with any question, before, during, or after the work is done. Free in-home estimates. There's a pitch, but we're not going to sit at your house for three hours and grind you down.

Which of the Four Do You Need in Fontana?

We do four things. Most people call us knowing something is wrong and not knowing which of the four it is, so here is how they actually differ.

  • Asphalt shingle roofs. The most common job we run. Old roof comes off to the deck, wood gets repaired where it needs it, new underlayment and shingles go on. We do not do overlays, so a shingle job here is always a full tear-off.
  • Tile replacement with new tile. This is when the tile itself is done: cracked, chipped, or a discontinued profile nobody can match. You are picking new material, so this one is a bespoke job. Eagle Roofing Products has a showroom in Rialto and we will sometimes go with you to handle actual profiles and colors before you commit.
  • Tile lift and relay. Your tile is fine, what failed is the underlayment beneath it. We lift the tile off, stack it, replace everything underneath, and set the same tile back down. Homeowners search for this as a replacement, and it is one, it replaces the waterproofing. It is just not a tile replacement.
  • Flat roofing. Low-slope sections, patio tie-ins, and small commercial buildings. Different material, different failure modes, different repair approach than a sloped roof.

The one that gets mixed up most is the middle two. If the tile is intact, you very likely need a lift and relay, not a tile replacement, and the price difference is not small. If someone quoted you all-new tile without going up to look at whether your existing tile is reusable, get a second look before you sign.

What Fontana Requires, Including One That Affects Tile

Fontana adopted the 2025 codes by Ordinance 1975 on October 28, 2025. It did not amend the roof classification table, so the floor for a house is the state minimum, Class C. It did rewrite one section to ban non-classified roofing anywhere in the city, which closes a loophole but does not change what most homeowners buy.

The one worth knowing if you are thinking about going from composition to tile: Fontana has required new single-family development since 1991 to be framed to carry concrete or clay tile. That is a development standard and not a reroof rule, so it does not force anything on you. What it means practically is that a Fontana tract home built after 1991 was supposed to be framed for tile weight from the start, which is often the deciding question on a conversion. We confirm it for your specific address rather than assuming.

One correction to a common assumption about Fontana: the fire hazard zones here are not only in the north. There is a Very High cluster at the southern end of the city around the Jurupa Hills as well as up north, with a clean middle in between. Which end you are on changes your material.

A tile lift and relay we wrapped in Fontana in August 2026. Same tile back on top, brand-new underlayment underneath, and our drone documented the whole thing.

And a tile replacement in Fontana: the old roof off down to the board deck, Titanium PSU30 underlayment and battens down, the new concrete tile loaded, and the drone shots as the crew capped the last ridge.

And a shingle roof replacement in Fontana in October 2026. It was leaking and the shingles were at the end of their life, so it came off down to the board deck. We kept the good boards, replaced the bad ones, and put ProArmor underlayment and Owens Corning Duration COOL shingles on the whole house. The whole job is in our Fontana shingle roof post.

And a leak in Fontana in October 2026 that turned out to be a valley. The water was showing up on the first story, and the flat roof below looked like the obvious suspect. It wasn't. A valley on the tile roof above had been leaking long enough for the water to run down the trusses and rot the deck under it. We took the tile off along the valley, cut out the rotted wood, put down new decking and new underlayment, and set the tile back. Water travels: where it shows up inside isn't always where it gets in. More on that in how we track down a leak.
