Won't blacken the look of rooftop fixtures
Excellent UV resistance
Lasts 2-3 times longer than asphalt roof sealants
Will twist, bend, stretch over gaps up to 2" wide,or compress to absorb just about any movement a home can dish out

Asphalt roof cement and patch (may become discoloured when applied over these products) - May damage polystyrene insulation
Do not use in areas of continuous submersion such as fish tanks or swimming pools - Can be used on rubber roof membranes such as EPDM (may wrinkle, but will not affect product or membrane performance)
PREPARATION:
Clean surfaces by removing all dirt and oil, and cutting away any loose roofing material
Surfaces previously sealed with silicone caulks should be cut away if possible or surfaces cleaned thoroughly with acetone solvent to get good adhesion as silicones can leave oils that interfere with adhesion
TOOLS NEEDED:
Standard caulk gun, plastic putty knife (optional),rag
WEATHER GUIDELINES:
In colder weather (below 40 degrees F), storing product at room temperature before application will make it easier to use
May be applied to wet surfaces however,repairs made when the roof is dry are usually better
May not be applied over frosty or icy surfaces
Frosty surfaces can be prepared by cleaning with alcohol
APPLICATION:
A 1/4" bead is a minimum (you need enough sealant mass to stretch and compress with roof movement) - Embed a seam sealing tape in Through The Rooffor repairing large holes and cracks
Tooling is the process of smoothing out the caulk bead to ensure good contact with the surface and a good appearance
"Float" lightly over the bead as pressing hard will remove too much sealant
A small putty knife with mineral spirits may be used to tool over the bead
A 10% soap solution is recommended to aid tooling if using your finger
CLEAN UP:
Tools may be cleaned with mineral spirits or paint thinner
Cleaning hands with a citrus-based or waterless hand cleaner
