4. Quality inspection and acceptance of the waterproof layer: Check whether the quality of the base layer (leveling layer) is qualified before construction of the waterproof layer; whether the waterproof layer materials and supporting materials are re-inspected and whether the weather conditions during the waterproof layer construction meet the requirements, and the detailed structure is Whether to follow the requirements to add an additional reinforcement layer; whether the coiled material has a spring line before laying, the coil construction sequence, whether the construction process is correct, whether the laying direction is correct, and whether the method meets the design requirements, whether the bottom surface of the coil is exhausted, and the coil Whether the overlap width of the material fully meets the requirements, whether the seam of the coiled material is reliable, whether the sealing is tight; whether the proportion of the waterproof coating is correct, whether it is uniform, whether the amount of each coating is appropriate, the uniformity of the coating, and the coating Whether the number of passes and the total amount of paint meet the requirements, whether the interval between brushing is sufficient, whether the orientation of the carcass reinforcement material, and the overlap width meet the requirements, whether the thickness of the coating waterproof layer meets the design requirements; rigid waterproof layer and structure Whether there is an isolation layer between the grassroots, whether the position of the split joint template is correct, whether the template is correct, whether the steel bar type and specifications meet the design requirements, the spacing and position of the steel bars are correct; whether the proportion of fine stone concrete is correct and whether the mixing is uniform , Whether the concrete of each grid is continuously poured, whether the concrete is compacted and polished, whether the second calendering is performed in time, whether the curing is timely and sufficient, whether the curing time meets the requirements, whether there are cracks, shells, sand and other defects on the surface. Whether the allowable deviation of flatness meets the requirements.

5. The quality inspection and acceptance of the protective layer: whether the waterproof layer has been successfully checked and accepted, whether measures have been taken to protect the waterproof layer during the construction of the protective layer; whether the light-colored paint protective layer is evenly painted, whether there is any leakage or bottoming phenomenon; mung bean sand , Whether the mica or vermiculite is evenly distributed and whether it is completely compatible; whether there is an isolation layer between the cement mortar, block or fine stone concrete protective layer and the waterproof layer, whether the position of the partition is correct, whether the cement mortar or concrete is dense Whether the surface has defects; whether the drainage slope of the protective layer meets the design requirements.

6. Quality inspection and acceptance of tile roof: Whether the tile and its supporting materials are qualified for sampling inspection, whether the quality of the base layer is qualified, whether the joints are reinforced, and whether the waterproof layer is checked and accepted; whether the water strip and the hanging strip of flat tile roof are consistent The material size matches, whether the paving nails are flat and firm; whether the flat tiles are laid firmly, whether fixing measures are taken when the slope is too large, whether the tile surface is neat, flat and straight, between the ridge tile and the flat tile, between the ridge tile, and the flat tile Whether the direction and size of the covering is correct, whether the roof and the sloping ridge are straight; whether the number of linoleum tile fixing nails is enough, whether the nails are flat and nailed, whether the nail caps are exposed, and whether the linoleum is in close contact with the base layer. Whether the butt seams between the tiles are staggered; whether the installation and fixing method of the roof panel is correct, whether the overlap width meets the requirements, whether the joints between the plates are sealed, whether the sealing is tight, whether the bolt fixing point is tightly sealed, the cornice line, flooding Whether the segment is straight.

7. Acceptance of insulated roof: Whether the waterproof layer is qualified before the construction of the insulation layer, whether measures are taken to protect the waterproof layer; whether the quality of the overhead insulation products meets the requirements, whether the roof is cleaned before the construction of the overhead slab, Is there any strengthening measures at the bottom of the buttresses, whether the distance between the buttresses is correct, whether the overhead slabs are paved with mortar, whether the alignment is smooth and stable, whether the height difference between adjacent slabs meets the standard, and whether the joints of the slabs are tightly packed; Whether the division and structure of the zone are correct, whether the position and size of drainage pipes, overflows, water supply pipes, and water holes meet the design requirements; whether the drainage slope of the planted roof is correct, whether the planting layer and hydrophobic layer materials meet the design requirements, and drainage Whether the position, size and elevation of the hole meet the design requirements.

8. Leakage inspection of roof waterproof layer: Check whether the roof has leakage, accumulated water, and whether the drainage system is unblocked. It should be carried out after rain or after 2 hours of continuous watering. For roofs that may be inspected for water storage, if there is any leakage during the storage time, the state of the leakage should be recorded, the cause should be found out, and repairs should be carried out in time until the roof has no leakage.
