To provide a lower roofing material that is thin but still provides excellent nail hole waterproofness, is lightweight and easy to carry, has good workability, and hardly creates a step even when overlapped, so that installation quality of an upper roofing material cannot be degraded.SOLUTION: A lower roofing material according to the present invention is a lower roofing material in which a low-density polyethylene film and non-woven fabric are stacked in order on both sides of an adhesive resin layer, and the adhesive resin layer is a rubber-based composition and has the minimum thickness of 90 μm or more, and the depth of the concave portion of the low-density polyethylene film is 5.0 μm or less.SELECTED DRAWING: Figure 1
【課題】本発明は、薄くても優れた釘穴防水性が得られ、軽量で持ち運びやすく、作業性も良く重ね葺きしても段差を生じ難いので屋根上葺材の施工品位を低下させない屋根下葺材を提供することを目的とする。【解決手段】本発明にかかる屋根下葺材は、粘着樹脂層の両面に低密度ポリエチレンフィルムおよび不織布が順に積層されている屋根下葺材であって、前記粘着樹脂層がゴム系組成物であり、最小厚みが９０μｍ以上であり、前記低密度ポリエチレンフィルムの凹部深さが５．０μｍ以下である屋根下葺材である。【選択図】図１
