A roof mount includes a base member and an attachment mount. The base member has a protrusion, and the attachment mount defines a hollowed region for receiving the protrusion to form a compression fitting. A substantially leak proof assembly is formed when the attachment mount is placed against the base member with a sealing material therebetween and a connecting element for coupling the attachment mount to the base member extends through the sealing material. A spacer extends the base member to a roof surface. The spacer is a hollow base stand, a tube, or a side wall of the base member. The spacer has a surface area covering the roof deck less than the surface area of a side of the base member facing the roof deck. The invention includes a method of limiting wind uplift of a roof. |

DETAILED DESCRIPTION Referring to FIGS.
1 and 2, a roof mount 10 for attaching structures such as safety railing and snow guards to a roof includes a base member 12 and an attachment mount 14.
When attachment mount 14 is bolted to base member 12 with a sealing material, e.
g.
, a membrane patch 13, positioned therebetween, a compression fitting is formed producing a substantially fluid tight seal between the mount and base member.
This limits leakage of moisture from snow, rain and melting ice at the mounting site, potentially damaging the roof deck below.
Base member 12 includes a flat plate 15 with flared protrusions 16 extending from a first side 18a of plate 15.
Plate 15 defines through holes 20 and protrusions 16 define through holes 22 aligned with holes 20.
Each pair of aligned holes 20, 22 receives an attachment member, e.
g.
, a threaded attachment bolt 24.
Alternatively, base member 12 can be cast with protrusions 16 and attachment bolts 24 formed integrally with the base member.
Mount 14 defines through holes 30, each having a first hollowed, flared region 32 for receiving a protrusion 16, and a second cylindrical section 34 for receiving a bolt 24.
Membrane patch 13 has through holes 36 for receiving bolts 24.
During installation on membrane roofing 40, after base member 12 has been secured to the roof, as described below, membrane patch 13 is placed over base member 12 with bolts 24 extending through patch holes 36.
Patch 13 is secured to roofing 40 by, e.
g.
, glue or heat welding.
Mount 14 is then placed over patch 13 with bolts 24 extending through mount holes 30.
Patch 13 entirely covers base member 12, leaving only bolts 24 exposed (as shown in FIG.
3).
Nuts 37 are threaded onto bolts 24 and tightened to secure mount 14 to base member 12.
The securing of mount 14 to base member 12 compresses membrane patch 13 with the portions of membrane patch 13 located between hollowed regions 32 and protrusions 16 creating a substantially leak proof compression fitting.
To attach base member 12 to membrane roofing 40, base member 12 includes additional flared centering protrusions 50 extending from a second side 18b of plate 15
