Show Asphalt Gives Wind Tight Utmi In Ciale Areas Roofing material used on barns and other farm buildings should be fire resistant, must be able to withstand all kinds of weather and still be economical to apply and maintain. Designed especially especial-ly to meet these requirements is 19-inch selvage edge roll roofing. This is an asphalt roll roofing which comes in strips 36 inches wide. Seventeen inches of the width is mineral-surfaced, and only this portion is exposed when he material is applied on a roof. -e mineral-surfaced part of one io lays over the 19-inch selvage unsurfaced part of the sheet jw it. Application of this type of roofing roof-ing is particularly recommended for barns. The barn usually is situated on high ground to facilitate facili-tate drainage and, consequently, is fully exposed to the wind. The roof also is subjected to high internal in-ternal wind pressures which develop de-velop when barn or haymow doors are open. Such pressures frequently are strong enough to damage a weak roof deck or poorly poor-ly applied roofing material. When asphalt strip shingles are used on a barn where high winds may be expected, a daub of quick-setting quick-setting cement the size of a fifty-cent fifty-cent piece should be placed under the center of each tab. This will prevent the wind from getting underneath the tabs of the shingles shin-gles where it can damage the roofing. |
