Modern microwave ovens usually weigh between 10 and 20 kilograms, and some microwave ovens with grilling functions or more heating functions may be heavier. As a high-hardness composite material, quartz countertops have sufficient compressive resistance to withstand such weight.

According to data from the National Storm Research Laboratory and several material testing agencies, high-quality clay tiles can withstand wind speeds of up to 120 miles per hour (about 193 kilometers per hour) after proper installation. This data is equivalent to the wind force level of a Category 3 hurricane.

It is not uncommon to see black stains on Roman clay tile roofs. These stains are usually formed due to the roof being exposed to the outside environment for a long time and being affected by a variety of natural factors. The main causes include mold, algae, air pollutants, etc.

● Starting at one end of the eaves, place the first tile on the waterproof membrane. ● Use a nail gun or hammer to secure the tiles to the wooden baseboard, fixing each tile at at least two points. ● Make sure the bottom edge of the tile is flush with the eaves, and use a level to check for straightness.

Typically, it is recommended that homeowners conduct a comprehensive inspection of clay tile roofs every 3 to 5 years. By performing regular inspections, homeowners can detect potential tile displacement, cracks, or other damage early.
