Leak Proof Your Roof With Our Mastic Roof Patch
The key to a professional roof job is to properly prep all seams, curbs, flashings and where roofing material terminates on parapet walls. This is not difficult to do and is essentially like applying spackle to sheetrock without having to have a perfectly smooth finished surface. Appearance is not critical; you just need to get the mastic where it's needed, and you don't have to do every seam or flashing, only the ones that need repair.
Easy to use roof patch is applied with trowel, stiff brush or flashing gloves to all cracks, holes and flashings that need repair. Also used to seal seams on Wood & Concrete Roofs and on Metal Roof Lap Joints and Screw Heads.
Guaranteed not to crack or chip off, permanently bonds with all ArmorGarage Roof Coatings.
Black Roof Cement vs. ArmorGarage Roof Mastic
The patch material you choose decides whether your repair lasts a season or lasts for the life of your roof.
Patch your roof with black roof cement and within a season or two it dries out, cracks and alligators into a guaranteed leak (left & center). ArmorGarage Roof Mastic (right) stays flexible and permanently bonded, so the repair holds for the life of your roof.
The cracked, dried-out surface shown above is what's called Alligatoring and is typical of aging tar-based roofs, or areas that have been patched with tar-based products such as Karnack Roof Cement. Patches like this are guaranteed leaks every time. The good thing is that these areas are easy to fix — instead of filling them in with the roof coating you would run your trowel over the area with the mastic and fill it in very quickly and more cost-effectively.
Why Retail Patch Products Fail On Roof Penetrations
Roof penetrations — vents, pipes, curbs and seams — are where most roofs start to leak. Here is the difference between flashing them with a cheap retail product and flashing them with ArmorGarage Roof Repair Mastic. There's no comparison in the quality of the patches.
Every dollar spent on retail-grade patch and coating products is a dollar wasted. They fail in a season or two — and start leaking which can permanently damage your roof and everything stored below it.
ArmorGarage roof mastic can be used with white Polyester, Fiberglass or Nylon roofing mesh where reinforcement is needed such as on joints on concrete roofs, flashing bases, curbs or edges. Do not use on EPDM, use suitable EPDM repair product for repair of seams and flashings such as paintable roof repair tapes.
Average coverage is approximately 150 lineal feet per gallon.
Clean repair area thoroughly and allow to dry. If using Roof Mesh on a repair area, apply thin coat of mastic first, then work mesh into the mastic with the serrated side of rectangle trowel until mesh is fully embedded and the mastic has come up through the mesh then apply a second thin coat of the mastic to fully cover the mesh, do not apply too thick, just enough to encapsulate the mesh. Allow Mastic to dry 24 to a max of 48 hrs and then apply Armor Roof Coating or our Armor Metal Roof Coating. Once properly applied it's impossible for water to penetrate through your roof seams, flashings or screws.
When using the Ponding Roof Coating over the mastic you must select either the 1 gallon or 2 gallon Ponding Mastic for those areas. Do not apply standard coating over ponding coating or ponding mastic. You may apply the ponding mastic and ponding coating over the standard mastic or coating but not the other way around. Always have a ponding water product overlapping the standard roof coating product.
