It is usually not coated with anything.
By the way, in such ceramic roofing material A′,
When it rains during construction, water intrudes into the outer periphery of the back side as shown in FIGS. 3a and 3b (the shaded area is the water intrusion part a). In addition, even after construction is completed in the rain, the outer periphery of the back side of the exposed part is
Water enters as shown in b. Another drawback was that the warping of ceramic roofing material A' increased at an accelerated pace when the weather turned clear after the rain.

A waterproof seal coating is applied to the roof material, and the part of the waterproof seal coating near the end of the roofing material body is made thicker.This structure solves the drawbacks of the conventional example. It is something. In other words, by applying the waterproof seal coating film 3 to the periphery of the back surface of the roofing material body 1 that corresponds to at least the exposed surface area, it is possible to prevent rainwater from entering the periphery of the back surface of the roofing material body 1, and to prevent rainwater from entering the periphery of the back surface of the roofing material body 1. By making the portion of the coating film 3 thicker near the end of the roof material body 1, it is possible to prevent rainwater from entering due to capillary action and to suppress warping due to water absorption.

裏面だけでもよい。 The roof material body 1 is made of asbestos slate, for example,
A weather-resistant waterproof coating film 2 is formed by applying weather-resistant paint such as acrylic paint to the surface and end surfaces of the roof material body 1, which may be made of any other ceramic material. It has been done. The thickness of this weather-resistant waterproof coating film 2 is 30 to 50 μm. Roofing material body 1
A waterproof seal coating film 3 is formed by applying a waterproof paint to the back surface of the cover. Examples of the waterproof paint include acrylic styrene paint, urethane paint, and epoxy paint. In this embodiment, the waterproof seal coating film 3 is thick at the periphery and thin at other parts. The thick layer portion 3a at the periphery of the waterproof seal coating 3 has a thickness of about 30 to 50 μm and the width of 30 to 70 mm, and the thin layer portion 3b has a thickness of about 5 μm. The waterproof seal coating 3 can be formed, for example, by first coating the thin layer 3b on the entire surface as shown in FIG. Form. The waterproof seal coating 3 does not have to be applied over the entire surface as described above, but may be applied only to the periphery, and may be applied not only to the entire periphery but at least to the back surface of the front end of the periphery.

である。[Effects of the invention] As described above, the ceramic roofing material of the present invention has a waterproof seal coating applied to the periphery of the back side of the roofing material body, so it can prevent rainwater from penetrating into the periphery of the back side of the roofing material body. It can suppress warping due to water absorption, and since rainwater does not enter the periphery of the back side, it reduces the risk of rainwater leaking due to wicking (pulling in).Also, since it does not absorb water easily, it is susceptible to frost damage due to water absorption and freezing. In addition, cracks occur over time during construction and exposure (this is caused by stress due to repeated water absorption and drying; in particular, asbestos-removed products with weak tensile strength (cracking resistance) of the roofing material are more prone to cracking than the front end. The waterproof seal coating can improve the sealing properties of the overlapped parts when the roof is overlapped and connected, and in addition, the waterproof seal coating can prevent The thicker parts near the ends of the roofing material not only suppress warping due to water absorption, but also cut off capillary action, allowing a waterproof seal coating to be applied to the center of the back surface of the roofing material. Even if it is not applied, it can prevent rainwater from seeping into the roofing material, and it can also thickly protect the contact area with the lower roofing material.
