Compared with traditional asphalt and clay tiles, colored stone coated roofing tile (usually referring to metal based colored stone coated roofing tile or resin based colored stone coated roofing tile) have significant advantages in multiple aspects. The following is a specific comparison:
Long lifespan: generally up to 30-50 years (metal based) or 20-30 years (resin based), far exceeding asphalt shingles.
Impact resistance: Metal or resin substrates are resistant to hail and strong winds (able to withstand typhoons above level 12).
Corrosion resistance: The surface colored stone layer and anti-corrosion coating are resistant to ultraviolet rays, acid rain, and salt spray, suitable for coastal areas.
Short lifespan: usually 15-20 years, prone to aging at high temperatures and brittle cracking at low temperatures.
Easy to damage: Strong winds can easily overturn, and high temperatures may soften and cause oil leakage.
Fragile: easily broken by impact, with increased structural load due to heavy weight.
Medium lifespan: about 30-50 years, but requires frequent replacement of damaged tiles.
Lightweight: Metal based colored stone coated roofing tile weigh only 1/3 of asphalt tiles and 1/10 of clay tiles, saving on roof structure costs.
Quick installation: Modular design, can be directly nailed or locked for installation, with high construction efficiency.
Medium weight: requires multiple layers of laying, with high requirements for the flatness of the base layer.
Heavy: The roof structure needs to be reinforced, installation is complex, and labor costs are high.
Seamless waterproofing: The metal substrate has strong overall integrity, and the resin based tiles have fewer joints, making them less prone to water leakage.
Maintenance free: No need for regular brushing or cleaning, the colored stone layer does not fade.
Easy to seep water: There are many seams, which may crack and mold after long-term use.
Maintenance required: Regular inspections and replacement of damaged tiles are necessary.
High water absorption rate: water may seep in rainstorm, and water absorption and freezing in winter are easy to crack.
Recyclable: The metal substrate can be 100% recycled, and the resin based part can be degraded.
Low pollution: Production energy consumption is lower than that of clay tiles (requiring high-temperature sintering).
Containing asphalt: may release VOCs (volatile organic compounds), which are difficult to degrade after disposal.
High energy consumption: The firing process consumes a large amount of energy and damages clay resources.
Rich colors: Surface colored stone particles can be selected in multiple colors, imitating natural stone or wood grain effects.
Strong modernity: suitable for various architectural styles (villas, commercial buildings, etc.).
Limited choices: mostly single tone, prone to fading.
Traditional style: limited to Chinese or European classical architecture, with a single color scheme (mainly red and gray).
The initial cost is higher: the unit price is higher than that of asphalt shingles, but it saves maintenance and replacement costs in the long run.
Initially cheap: but frequent replacement may result in higher overall costs.
High overall cost: The costs of materials, transportation, installation, and structural reinforcement are all relatively high.
Colored stone coated roofing tile: pursue long-term durability, modern beauty, typhoon/rainstorm prone areas.
Asphalt shingles: Low rise buildings with limited budget and short-term use.
Clay tiles: a traditional architectural style project with no weight restrictions.
The comprehensive performance advantages of colored stone coated roofing tile are obvious, especially suitable for projects with high requirements for roof life and low maintenance.
