The skylights at a metal fabrication shop in Butler, WI were aged and cracking, with small holes from animals, debris or traffic. Previous asphalt repairs were failing. The skylights were pressure washed, cracks and holes filled with silicone, a base coat applied to block asphalt oils, and then a thick coat of white silicone to encapsulate and protect the substrate for 20 more years of use. This new silicone approach successfully solved the water penetration issues that previous roofing companies were unable to fix.

1. Falls Manufacturing/Boschert Precision Machinery Skylights
Case Study
Where: Butler, WI
Roof Type: Ballasted
Skylight Material: Aluminum Coating
Skylight pitch: 6” to 12”
Roof or Building use: Metal Fabrication Shop
Number of Skylights: 6
Size of Skylights: 60’x12’
Total Size: 6,000+ Sqft
Building Height: 20’
Condition/Problem: The surface of the skylights was aged
and as a result it had started cracking and splitting. There
were also areas in the surface that had small holes that may
have been created by animals, flying debris, or foot traffic. An
asphalt based product had been previously used to repair
other parts of the skylights and was starting to break down
and fail.
Solution: Pressure washed all six skylights making sure to
remove all dust, dirt, and debris ensuring a clean substrate
for the silicone to be applied. After the skylights were cleaned
Henry 600 Butter Grade Silicone was used to fill any cracks,
splits, or holes. Henry 294 Base Coat and Sealer was used to
guarantee adhesion and block any of the oils in the asphalt
repairs from bleeding through the silicone. Finally, a nice
thick coat of Henry 988 White Silicone was applied to all six
skylights, encapsulating and protecting the original substrate
from the elements, allowing these skylights to last another
20+ years.
Result: The owner of the building had multiple repairs done by multiple roofing companies and none of
them could fix the problem. We came in with a new approach and a different product and they haven’t
had water penetration since.
