Faida ya bei ya chini na ujenzi rahisi wa tile ya lami ni dhahiri, lakini ikiwa maisha ya huduma ya tile ya lami ni mafupi sana, matengenezo ya marehemu ni jambo la shida sana, lakini huongeza ugumu wa gharama za ujenzi na ujenzi.

In fact, the original intention of asphalt tile design is for wooden house design. Because the life of the cabin itself is short, and the load-bearing capacity is weak, so the need for a light and thin tile, asphalt tile emerged at the historic moment, instead of the original linoleum cloth, become the best choice for the cabin roof.

Hadi sasa, matofali ya lami yamepatikana kwa zaidi ya miaka 60, baada ya zaidi ya miaka 60 ya maendeleo, masuala yote ya matofali ya lami yameboreshwa, mabadiliko ya wazi zaidi ni kwamba tiles za lami zina viwango vya kitaifa.

In strict accordance with the national standard production of asphalt tile, the service life of single layer of asphalt tile can guarantee 20 years of life, the service life of double layer of asphalt tile can guarantee 30 years.

Hiyo bado sio ndefu kama vigae vya kitamaduni, ambavyo vinaweza kudumu hadi miaka 50. Lakini kulingana na kiwango cha sasa cha maendeleo ya miji ya China na maisha ya ujenzi, maisha ya huduma ya shingles ya lami ya miaka 30 yanatosha kuendana na majengo mengi. Kwa hiyo katika miaka 10 iliyopita, upeo wa matumizi ya matofali ya lami umekuwa mkubwa sana, wote wana paa la mteremko, kuna matukio ya kutumia matofali ya lami.
