T HE all-mineral roof-made of asbestos rock-caps the permanent building. Flexible felts, artistic shingles - or strong corrugated sheets for heavy duty industrial service - all these are Johns-Manville Asbestos Roofings. They are fire-repellent, protecting your property against roof-communicated fire and providing against the day when public opinion will force legislation demanding a fire-retardant roof on your building. They are water proof, practically immune from the attacks of time and need no periodic painting or coating. Johns-Manville Roofing Responsibility protects the user of this roofing through an exclusive system of registration. When you register your roofing, it is our obligation to see that your roofing gives service as promised when sold. H. W. JOHNS-MANVILLE CO.
