[82]TORCH ON ROOF ON A MOBILE HOME IN SURREY B.C. |
|
ON OLDER MOBILE HOMES, WITH CORRUGATED METAL ROOFS, THE PROPER APPLICATION OF A TORCHON MEMBRANE, USUALLY IS THE ONLY OPTION.
|
|
 |
THIS IS A TYPICAL 40 YEAR OLD METAL SEAMED ROOF.THE METAL PANELS ARE STRETCHED OUT AND FULL OF DIPS AND VALLEYS.
|
|
|
 |
THERE'S NO WAY OF INSTALLING A TORCHON MEMBRANE DIRECTLY ONTOP OF THIS DIRTY, PATCHED, UNLEVEL, ROCK'N ROLL METAL ROOF.
|
|
|
 |
WE INSTALLED A WATER PROOF VAPOUR BARRIER OVER THE METAL PANELS, BEFORE APPLYING OUR PLYWOOD OVERLAY.
|
|
|
 |
IN PREPARATION FOR THE NEW TORCHON MEMBRANE, WE APPLIED 3/8 PLYWOOD TO LEVEL OFF THE ROOF AND PROVIDE A STURDY, SMOOTH SURFACE. WE USED SCREWS AND PLATES TO SECURE THE PLYWOOD.
|
|
|
 |
WE SHEARED OFF THE GABLE TRIM FLUSH WITH EDGE OF THE ROOF.
|
|
|
 |
WE INSTALLED NEW FLASHINGS TO THE PERIMETER OF THE ROOF.
|
|
|
 |
THE APPLICATION WAS A PROPER 2 PLY TORCHON MEMBRANE, USING A 180 GRAM BASE PLY, FULLY ADHERED TO THE SUBSTRATE, AND A 250 GRAM GRANULATED CAP SHEET.
|
|
|
 |
WE INSTALLED NEW METAL ROOF VENTS, AND LEAD PLUMBING PIPE FLASHERS.
|
|
|
 |
WE ENDED UP WITH A SMOOTH, STURDY, WALKABLE, WATERTIGHT ROOF THAT SHOULD LAST, I'M GUESSING 20 YEARS OR MORE. THE OWNER WAS VERY SATISFIED WITH THE JOB.
