Liquid applied roofing systems and methods for forming roofs

1. A method of forming a sloped roof, comprising:

obtaining a base layer comprising at least one of a permeable mesh, woven fabric, non-woven fabric, plastic, foam material or combinations thereof;

applying the base layer over a roofing substrate of the sloped roof;

positioning a permeable underlayment along at least a portion of the roofing substrate, at least a portion of the underlayment partially overlapping the base layer; and

applying a liquid roofing material over the base layer and the underlayment such that the liquid roofing material penetrates through the at least a portion of the base layer and at least a portion of the underlayment to form a covering having a substantially uniform thickness along the sloped roof;

wherein the sloped roof comprises only one liquid roofing material;

wherein the base layer is configured to control flowing of the liquid roofing material along the slope of the sloped roof as the liquid roofing material is distributed along the sloped roof;

wherein at least a portion of the liquid roofing material passes through at least a portion of the base layer so as to substantially seal the base layer;

wherein the underlayment is sufficiently permeable so as to enable penetration of at least a portion of the liquid roofing material therethrough;

wherein the sloped roof has a slope of at least 30 degrees and does not include a shingle.

2. The method of claim 1 , wherein the applying the base layer comprises attaching the base layer to the roofing substrate using fasteners.

3. The method of claim 1 , further comprising attaching a roof mounted structure over the base layer and to the roofing substrate with fasteners, wherein a portion of the base layer extends past a bottom surface of the roof mounted structure; and wherein the liquid roofing material is adapted to flow about the fasteners and at least partially into openings formed in the roofing substrate by the fasteners.

4. The method of claim 3 , wherein the roof mounted structure comprises a drip edge having a forward edge positioned over a lower edge of the roofing substrate; and wherein a water drainage path is defined along the roofing substrate and over the forward edge of the drip edge.

5. The method of claim 1 , further comprising positioning spacers between the base layer and the roofing substrate, wherein a space is defined below the base layer; and receiving at least a portion of the liquid roofing material in the space.

6. A method of forming a sloped roof, comprising:

obtaining a base layer comprising a permeable mesh, woven fabric, non-woven fabric, plastic, foam material or combinations thereof;

wherein the base layer comprises a permeable sheet configured with a plurality of restraining features arranged along an upper surface of the base layer;

wherein the restraining features comprise projections, cuts, cups, fins, tabs, or combinations thereof;

positioning the base layer over a roofing substrate of the sloped roof; and

coating the base layer with a liquid roofing material to form the sloped roof;

wherein the base layer is sufficiently permeable to allow penetration of the liquid roofing material therethrough and the restraining features are configured to restrain a flow of the liquid roofing material along the roofing substrate to control flowing and sagging of the liquid roofing material along the sloped roof as the liquid roofing material is distributed along the upper surface of the base layer to form a coating having a substantially uniform thickness;

wherein the sloped roof has a slope of at least 30 degrees and comprises only one liquid roofing material.

7. The method of claim 6 , further comprising introducing fillers into the liquid roofing material prior to coating the base layer with the liquid roofing material.

8. The method of claim 6 , wherein the liquid roofing material further comprises at least one of bulking materials, fillers, or combinations thereof.

9. The method of claim 6 , further comprising attaching a roof mounted structure to the roofing substrate with fasteners; wherein the liquid roofing material is adapted to flow about the fasteners and at least partially into openings formed in the roofing substrate by the fasteners.
