Recently, many readers in the background of the private letter to consult: “my home roof wants to replace the resin tile, but the market price of the product ranges from dozens of dollars to hundreds of dollars, the gap is also too big. How long is the general life of resin tile? In the end, how to choose not to step on the pit?”
This question does ask the point. Regarding the claims about the life span of resin tiles, some on the Internet say 30 years, some say 10 years, and some say that they are brittle and cracked in 3 years, so who is right in the end?
To answer this question, first figure out one thing:Different grades of resin tiles, the life expectancy is vastly different。
First, how long is the general life of resin tile? The difference between different grades is huge
How long is the general life of resin tilesThe answer to this question is not a fixed number, but depends on the product quality level. According to market feedback and sampling results from testing organizations, there is a significant difference in the effective service life of resin tiles of different grades:
| Product quality level | service life | thrust |
|---|---|---|
| Quality products (new material production) | 20-35 years | ASA surface layer thickness ≥ 0.15mm, using imported super weather-resistant materials, color difference ΔE ≤ 5 within 10 years |
| General products (mixed with recycled materials) | 6-12 years | The ASA layer is thin or contains recycled materials, color fading and chalking may occur at a later stage. |
| Inferior products (recycled materials mainly) | 3-8 years | Cracking and color fading in two or three years, rapid failure of waterproof function |
The use of imported ASA raw materials, thickness ≥ 0.1mm of high-quality resin tiles, under normal use conditions can be guaranteed for 10 years ΔE ≤ 5, the actual service life of up to 25-35 years, the regular brand to provide more than 10 years of warranty, after-sales service is guaranteed!Waterproof function is completely ineffective. The poor-quality products with ABS pretending to be ASA, installed one or two years after the white color, three or five years on the surface cracking, waterproof function completely failed!。
How long is the general life of resin tiles, picking the right product is 20+ years, picking the wrong product 3 years and you have to replace it again.
Second, why some resin tile two or three years on the bad?
1. Surface fabrics make all the difference
Weathering and aging resistance of resin tiles.90% Depends on the surface material。
High-quality products use ASA (acrylonitrile-styrene-acrylate copolymer) as the surface layer, which does not contain unsaturated chemical bonds in its molecules and can effectively resist the damage of ultraviolet rays. In the 12,000-hour artificial aging test conducted by the National Testing Center for Chemical Building Materials, the color difference value ΔE of high-quality resin tiles is only 2.23, which is far lower than the upper limit allowed by the national standard.。
Inferior products use ABS to replace ASA, and even directly with recycled material production. the anti-aging weather resistance of ABS material is only one-tenth of ASA, in the ultraviolet radiation will be rapidly degraded, resulting in a few months of fading, surface cracking, brittleIn other words, under the same usage environment, the life span of resin tile made of ABS is almost 10 years worse than ASA. In other words, under the same usage environment, the lifespan of resin tiles made of ABS is nearly 10 years worse than ASA.
2. The “invisible trap” of recycled materials”
A large number of low-priced resin tiles on the market come from recycled materials. Recycled materials have been melted at high temperatures and processed many times, in which the polymer chain has been broken, and may also be mixed with impurities. The tiles made from this type of material, intuitively manifested as dark color, uneven texture, brittle.The color of these products usually fades in one to two years after installation. These products are usually installed one to two years after the fading of the color, about three years of surface cracking, waterproof function fails!。
3. Irregular installation accelerates deterioration
No matter how good the material is, it is useless if the installation is not standardized. Common installation problems include: excessive screw spacing leading to loose tiles; improperly treated seams leading to water seepage; failure to reserve expansion and contraction joints leading to thermal expansion and contraction and extrusion deformation; roof slope is too small leading to long-term waterlogging and so on.。
Third, the key indicators affecting the life of the resin tile, look before you buy!
✅ Look at the thickness of the ASA layer
The national standard requires that the thickness of the ASA layer should not be less than 0.15mm, so make sure to confirm this indicator when you buy, or ask for the artificial aging test report directly. An artificial aging test report issued by a third-party organization is the most direct basis for judging the real life of resin tiles.。
✅ Look at the length of the artificial aging test
According to the industry's common conversion, artificial accelerated aging test 5000 hours of products, the theoretical service life is equivalent to more than 15 years; test length of 10,000 hours, the projected life of about 20 years or more; through the 12,000 hours of aging test of the product, the life of up to 25 years or more!。
✅ Look at the raw material ingredients
Require manufacturers to provide material testing reports to ensure that the surface layer is imported ASA film, not ABS or mixed materials. High-quality resin tiles are co-extruded with new ASA resin + PVC and other raw materials.。
✅ Easy on-site identification
-
take a look at the exterior: High-quality tiles have a uniform luster and a flat surface; low-quality tiles are dull in color and prone to black spots.
-
Foot test: With a foot on the crest position, good tiles step on the flattened release can be quickly restored to its original shape; poor quality tiles step on the cracks or do not rebound.
-
Flame retardant test: Burn the corner of the tile with an open flame, the high-quality tile will be extinguished immediately after leaving the fire, and only a small amount of smoke will be produced; the low-quality tile will continue to burn and emit a pungent odor.。
Fourth, how to make resin tile “live” longer?
✅ Proper installation is key
-
Roof slope ≥ 15 °, too small a slope is easy to accumulate water, accelerated aging。
-
Use special self-tapping screws to fix, avoid directly knocking the surface of the tile, screw spacing control in 50-60cm, to ensure that the tile and the roof frame tightly affixed.。
-
Reserve expansion joints (usually set up every 3-5 meters) during installation to avoid extrusion and deformation caused by thermal expansion and contraction.
✅ Regular maintenance can't be understated
-
Sweep the tile surface once a quarter or before the rainy season, use a soft brush or low-pressure water gun rinse, avoid high-pressure water gun impact joints。
-
Every year in spring and fall each check the tile surface whether there are cracks, warping, cracked seams and other issues, timely repair with repair adhesive or sealant repair。
-
Selecting ASA resin tiles containing UV stabilizers, together with regular maintenance, can extend the service life by 5-8 years.。
Summarize: resin tile general life long, the decision is in your hands!
Back to the original question:How long is the general life of resin tiles？
The answer is clear:High-quality regular products up to 20-35 years, inferior products only 3-8 years or even shorter. The market's skepticism about the longevity of resin tiles - some are still intact after 30 years, others crack and leak after 3 years - is actually true, it's just that they're not buying the same product at all.
One sentence summary:Choose the right material, recognize the standard, scientific installation, regular maintenance, resin tile with two or three decades is not a dream; cheap to buy poor quality goods, three or five years will have to re-roofing, spend money and add blockage.
