• 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)

• 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

• Foam or course bristle brush, rag

• 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

• Should be applied between 1/8" and 1/4" thick
• Make sure it is worked well onto the surface so good contact is achieved
• Embed a seam sealing tape in Through The Roof for 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

• Tools may be cleaned with mineral spirits or paint thinner
• Cleaning hands with a citrus-based or waterless hand cleaner

• The most common leak is around a pipe, vent, skylight, cable, chimney, parapet wall or anything that penetrates through your roof deck

• Cracks, splits and holes can form in aging roof materials
• If small areas of your roofing have become brittle, water can seep through tiny cracks, which may not look like a leak source
• NOTE: Too much deterioration can mean you need to replace your roofing material (Through The Roof is not meant as a roof replacement)

• Start by looking directly above the inside leak
• Inspect pipes, vents and cables - anything which was installed by cutting a hole in your roof
• Also check metal flashing around chimneys, dormers and parapet walls
• Look for signs of pulling away, turned up roofing edges, cracked roof cement, rusted metal, loose and cracked mortar
• Next, try tracing water from the inside
• Leaks are not always directly above the leak inside because water can run between layers of roofing material and along pipes, etc
• Look under your roof for a water path along ducts, pipes, beams and electric wires to trace it to where it comes through your roof
