Flat roofs can be maintained to stop leaks, eliminate blisters and improve energy costs. These photos show the steps:
Flat roof system materials include elastic roofing sealer, mesh and white acrylic. To the right, the crew has emptied the winter-grade version of the elastic sealer. |

 |
Blister repair is performed before the "runs" of mesh are applied. With the removal of the old delaminated roofing, elastic roofing sealer is squeegeed over the area. Then the area is reinforced with #15 fiberglass felt. Blistered area is ready for the application of the base of the work. |

Flat roof base work
 |
Base work: 1. Squeegee elastic roofing sealer over blister repaired area 2. Roll mesh in a straight line, overlapping seams three inches 3. Brush mesh to embed into elastic roofing sealer |
 |
 |
At this point, the project is ready for the application of acrylic in the seaming to bond the mesh. |

Parapet base work
For parapet work on flat roofing, base work contours the logical outline.
 |
 |
| On the upper roof in the first photo, mesh is applied to the outside edge of the parapet. | Base work on parapet has been seamed and coated once with white acrylic. Second coating due. |
Acrylic seaming of mesh
Seaming binds the overlaps of the mesh. First, acrylic is brushed down under the mesh. Then the overlap is brushed into the lower lap with acrylic. |
