Methods and systems for imparting visual features to liquid applied residential roofs
Methods and systems for imparting visual features to a liquid applied roof, such as for forming a residential roof, include using overlapping strips of underlayment, underlayment with varying densities, underlayment with raised features, and underlayment with a gridded surface among others. Visual features also can be imparted by mixing different colors of a liquid applied roofing material, embedding floating particles in a liquid applied roofing material, embedding colored flakes in a liquid applied roofing material or spraying colored flakes onto a liquid applied roof before skinning, creating texture as the liquid applied roofing material is applied, and using stencils or printing techniques to impart visual features.
1. A roof system, comprising:
a roofing substrate;
wherein the roofing substrate is oriented at a pitch of at least 30 degrees;
a base layer positioned along the roofing substrate;
a liquid applied roofing material applied to the base layer; and
wherein the base layer comprises a woven material, nonwoven material, mesh, open cell foam, or a combination thereof, configured to at least partially absorb the liquid applied roofing material;
a plurality of aesthetic visual features defined along at least a portion of the base layer;
wherein the liquid applied roofing material comprises a clear or translucent liquid sealant material;
wherein the liquid applied roofing material configured to seal the base layer and form an exposed surface of the roof system upon curing;
wherein at least a portion of the aesthetic visual features are visible through the liquid applied roofing material upon the curing of the liquid applied roofing material;
wherein the base layer is configured to absorb the liquid applied roofing material such that the liquid applied roofing material penetrates the base layer and into contact with the roofing substrate sufficient to secure the base layer to the roofing substrate without fasteners or adhesives.
2. The roof system of claim 1 , wherein the aesthetic visual features comprise a pattern, image, design, folded or layered construction, texture, or combinations thereof.
3. The roof system of claim 1 , wherein the base layer comprises a plurality of fabric strips; and wherein at least a portion of the fabric strips are configured to define an appearance of a peak, valley, shingles, a corrugated or standing seam roof, or combinations thereof.
4. The roof system of claim 1 , wherein the base layer comprises a plurality of fabric strips; and wherein at least a portion of the fabric strips are arranged in an overlapping alignment configured to define lighter or darker appearing areas when viewed through the liquid applied roofing material.
5. The roof system of claim 1 , wherein the clear or translucent liquid sealant material of the liquid applied roofing material comprises polysiloxane, polyurea, polyurethane, silane modified ether, silane modified ester, silane modified polyurethane, silane modified polyurea, epoxy, acrylic, poly acrylic, precursors configured to crosslink after application to form a polymer, or combinations thereof.
6. The roof system of claim 1 , wherein the liquid applied roofing material further comprises a dye, pigment, fillers, or combinations thereof, configured to provide the liquid applied roofing material with a color, hue, texture, pattern, or combinations thereof.
7. The roof system of claim 1 , further comprising an additional liquid applied roofing material applied to the base layer, the additional liquid applied roofing material configured to form at least a portion of the aesthetic visual features.
8. The roof system of claim 1 , wherein the liquid applied roofing material comprises a mixture of a plurality of liquid applied roofing materials, each having a different color or hue.
9. The roof system of claim 1 , wherein the base layer comprises a density of 10 grams per square meter to 30 grams per square meter.
10. A roof system, comprising:
a roofing substrate oriented at a pitch of at least 30 degrees;
a base layer positioned along the roofing substrate;
a plurality of aesthetic visual features defined along at least a portion of the base layer; and
a liquid applied roofing material applied to the base layer, the liquid applied roofing material comprising a clear or translucent liquid sealant material adapted to substantially seal the base layer and form an exposed surface of the roof system upon curing;
wherein the base layer comprises a woven material, nonwoven material, mesh, open cell foam, or a combination thereof, configured to at least partially absorb the liquid applied roofing material;
wherein at least a portion of the aesthetic visual features are visible through the liquid applied roofing material upon the curing of the liquid applied roofing material;
wherein the base layer is configured to absorb the liquid applied roofing material such that the liquid applied roofing material penetrates the base layer and into contact with the roofing substrate sufficient to secure the base layer to the roofing substrate without fasteners or adhesives.
11. The roof system of claim 10 , wherein at least some of the aesthetic visual features comprise a pattern, image, design, texture, or combinations thereof.
12. The roof system of claim 10 , wherein the base layer comprises a plurality of fabric strips; wherein at least a portion of the fabric strips are arranged parallel to one another, folded, layered, or combinations thereof, so as to define an appearance of a peak, valley, shingles, a corrugated or standing seam roof, or combinations thereof.
13. The roof system of claim 10 , wherein the base layer comprises a plurality of fabric strips; wherein at least a portion of the fabric strips are arranged in an overlapping alignment to define lighter or darker appearing areas when viewed through the liquid applied roofing material.
14. The roof system of claim 10 , wherein the clear or translucent liquid sealant material of the liquid applied roofing material comprises polysiloxane, polyurea, polyurethane, silane modified ether, silane modified ester, silane modified polyurethane, silane modified polyurea, epoxy, acrylic, poly acrylic, precursors configured to crosslink after application to form a polymer, or combinations thereof.
15. The roof system of claim 10 , wherein the liquid applied roofing material further comprises a dye, pigment, fillers, or combinations thereof, configured to provide the liquid applied roofing material with a color, hue, texture, pattern, or combinations thereof.
16. The roof system of claim 10 , further comprising an additional liquid applied roofing material applied to the base layer, the additional liquid applied roofing material configured to form at least a portion of the aesthetic visual features.
17. The roof system of claim 10 , wherein the liquid applied roofing material comprises a mixture of a plurality of liquid applied roofing materials, each having a different color, tint or hue.
18. The roof system of claim 10 , wherein the aesthetic visual features include printing or textures applied along the base layer and configured to create an appearance of a roofing shingle, roofing tile, or combinations thereof.
