Lightweight Tile Roofing
Lightweight tile is concrete roofing tile engineered to weigh less, so a home framed for asphalt shingle or wood shake can be reroofed in tile without adding structural reinforcement. Roof Doctors installs, repairs, replaces, inspects, and certifies tile roofs, including lightweight tile, for homeowners across our service area. Licensed since 1987, no advance deposit.
What Lightweight Tile Is and Who It Suits
Lightweight tile is concrete roofing tile made with a lighter aggregate so it weighs less than standard tile. Manufacturers describe it at roughly 5.5 to 7 pounds per square foot, under 6 pounds per square foot in many lines, against about 9 pounds per square foot for standard concrete tile. Because it weighs close to half as much, a roof framed for a lighter material can often carry it, which is why its main use is reroofing a home originally framed for asphalt shingle or wood shake without adding structural reinforcement.
Lightweight tile tends to make sense when
- You want a tile roof on a home that was framed for asphalt shingle or wood shake
- You are reroofing and want to avoid adding structural reinforcement
- You want the look and fire resistance of tile at a lighter load
- You want individual tiles replaceable without redoing the whole roof
Trade-offs to consider first
- A structural inspection should confirm the roof can carry the new load before you commit
- Like all tile, it is fragile underfoot and can crack from impact or foot traffic
- It costs more than asphalt shingles to install
- The underlayment beneath it will need replacing before the tile does
Lightweight Tile Profiles
Lightweight tile comes in the same three profiles as other tile; the profile is the shape, not the material.
Barrel (Spanish and Mission)
The classic curved barrel profile of Spanish and Mission roofs, with deep shadow lines.
Flat
A clean, low-shadow flat profile that suits contemporary and transitional homes.
Low-Profile
A gentle S-curve between barrel and flat, a popular all-around look.

Lightweight Tile Across Our Service Area
Two things that matter for lightweight tile across our service area.
Reroofing over existing framing
Lightweight tile's main use is reroofing. Because it weighs roughly half what standard tile does, a home framed for asphalt shingle or wood shake can often take a tile roof without added structural work. Manufacturers note that lightweight tile under 6 pounds per square foot generally does not require an engineer's certification before installation, while standard tile usually does on a retrofit.
Class A fire for high fire zones
Manufacturers state lightweight tile passes the same tests as standard concrete tile, including a Class A fire rating, the highest fire classification, which matters in high fire zones.
Underlayment and Lifespan
Lightweight tile is concrete tile, and manufacturers state it is as durable as standard tile, lasting 50 to 100 years or the life of the structure when properly installed. As with any tile, the tile outlasts the underlayment beneath it, which is the actual waterproofing layer and is typically replaced every 20 to 30 years. When it reaches the end of its life, the roof is re-laid, which means the following.
Lift and Stack the Tile
The existing tile is carefully lifted and stacked so sound tiles can be reused.
Remove the Old Underlayment
The worn underlayment is stripped down to the deck.
Inspect and Repair the Deck
The decking is checked for dry rot or damage and repaired where needed.
Install New Underlayment
A new waterproof underlayment is installed, the layer that actually keeps water out.
Re-Lay the Tile
The tile is re-laid, with any cracked or broken pieces replaced and matched.
Order a Roof Inspection
Request an inspection and a knowledgeable technician will assess your lightweight tile roof and its underlayment and provide a written estimate within 1 to 2 business days. No advance deposit.

Lightweight Tile Roofing: Frequently Asked Questions
What is lightweight tile roofing?
Lightweight tile is concrete roofing tile made with a lighter aggregate, such as expanded shale, so each tile weighs less than standard concrete tile. It looks like standard tile and comes in the same profiles, but manufacturers describe it at roughly 5.5 to 7 pounds per square foot, under 6 pounds per square foot in many lines. Its main purpose is to put a tile roof on a home that was not framed for the weight of standard tile.
How much lighter is it than standard concrete tile?
Manufacturers describe lightweight tile at roughly 5.5 to 7 pounds per square foot, and many lines come in under 6 pounds, against about 9 pounds per square foot for standard concrete tile. Per roofing square that is roughly 550 to 650 pounds for lightweight tile versus about 900 to 1,100 pounds for standard tile, so it weighs close to half as much.
Can I put lightweight tile on a house that has asphalt shingles now?
Often, yes, and that is the main reason it exists. Because lightweight tile weighs close to what an asphalt shingle roof does, a home framed for shingle can frequently carry it without added structural reinforcement. Manufacturers note that lightweight tile under 6 pounds per square foot generally does not require an engineer's certification, while standard tile usually does on a retrofit. A documented inspection confirms your structure can carry the new load before any work begins.
Does lightweight tile last as long as standard tile?
Manufacturers state it does. Lightweight tile is concrete tile and is described as passing the same durability, strength, and weather tests as standard concrete tile, with the same long service life, 50 to 100 years or the life of the structure when properly installed. As with any tile roof, the underlayment beneath it wears out first and is typically replaced every 20 to 30 years.
Is it as strong underfoot?
Manufacturers state lightweight tile meets the same strength and durability tests as standard concrete tile. That said, all tile is fragile underfoot and can crack from foot traffic, so a lightweight tile roof should be walked only by a roofer who knows how to walk tile, the same as any tile roof.
Does it need the same underlayment?
Yes. Lightweight tile is concrete tile, so it is laid over the same waterproof underlayment as standard tile. The underlayment is the actual waterproofing layer, and it wears out before the tile does, typically within 20 to 30 years, at which point the roof is re-laid over a new underlayment.
Schedule Your Lightweight Tile Roof Inspection
A licensed inspector will assess your lightweight tile and the underlayment beneath it, confirm your structure can carry the load, document any issues, and provide a written estimate. No obligation, no advance deposit.
