Butyl tape and sealants

Butyl tape and roofing sealants
Butyl sealant tape seals the side and end laps between sheets, and roofing sealants finish flashings, gutter joints and penetrations. We supply them with your sheets, so the whole roof arrives together.

Sealing the laps
Where two sheets overlap, at the side laps along the slope and the end laps where one sheet runs on to the next, a strip of butyl sealant is laid in the lap before the sheets are fixed. Butyl stays flexible rather than setting hard, so the joint stays sealed as the roof moves with the temperature.
How much you need
The number and size of strips depends on the sheet profile, the length of the lap and the pitch of the roof, and the sheet maker's fixing details set it out. Tell us the roof and we'll work out the tape with the sheets.
Sealants
Flashing joints, gutter joints and penetrations are finished with a sealant made for metal roofing. We supply sealants from leading makers.
Questions we’re asked
What is butyl tape used for on a metal roof?
Sealing the side laps and end laps between sheets, and under flashings, so wind-driven rain can't get through the joints.
