A roof must be more than fire resistant to be safe. The beating sun, extreme cold, heavy rains and winds are also constantly threatening the safety of the structure it must protect.

Pioneer Yosemite Rock Surfaced Shingles are endorsed by the National Board of Fire Underwriters but flawless fire resistance is only a part of their function.

The impregnability of crushed stone, laid on asphalt-coated felt, makes them | 00/o efficient ! They prevent the leakage that loosens and spoils plastered walls and ceilinp-1lsy eliminate the damp seepage that slowly warps and rots the very framework of the structure and they protect mansion and cottage alike. There is a specified type and design for every kind of roof. It took more than thirty years of cqnstant experimentation to perfect Pioneer Yosemite Rock Surfaced Shingle-they are a proven product.

All lumber, building material and hardware dealers sell them in beautiful shades of red, green, blue black, golden brown, and in the new Nile, Copper, Autumn and Multi-color Blende.

For re-roo6ng, Pioneer Yosemite Rock Surfaced Shingles ean be sold on easy time payments. Inquire about our plan for financing your prospects.
