The mechanism
Roofs don’t wear out. They dry out.
An asphalt shingle is asphalt, a reinforcing mat and a layer of protective granules. Almost every failure starts the same way — the asphalt loses its oils, goes brittle, and stops holding onto the granules. ShingleLock puts oil back into the asphalt.
Watch it work
Step 1 — Applied
Sprayed across the surface in a single pass. No tear-off, no disruption.
Step 2 — Absorbed
Draws down into the asphalt rather than sitting on top of it. There is no film left behind.
Step 3 — Locked
The asphalt regains flexibility and the granules bond back to the mat.

Shingles dry out
Asphalt shingles start flexible because the asphalt is full of oils. Sun and heat drive those oils off year after year. The asphalt hardens, the mat loses its ability to flex, and the granules bonded to the surface start letting go.
- 02
Granules shed
Those granules are the shingle's shield against UV. Once they wash into the gutter faster than the asphalt can hold them, the mat underneath is exposed and degrades quickly. This is the point most roofs are condemned.

ShingleLock penetrates
The emulsion is sprayed onto the roof and absorbs into the asphalt rather than sitting on top of it. It is not a coating, a sealant or a membrane — there is no film left on the surface.

The asphalt softens and grips
Once absorbed, the asphalt regains flexibility and the bond to the granules tightens. In testing, aged shingles gained flexibility and stiffness at the same time, and held significantly more of their granules than untreated shingles of the same age.
What the lab measured
Tested by Certerra, 2025, against untreated shingles of the same age.
How it’s applied
- Mix
