        Q:Can this be placed over shingles?
        by|Mar 10, 2024
        1 Answer
        Answer This Question

        A:  Hi Justme, we don't recommend to use the Lanco Aqua-Proof Primer over shingles, this product is like a liquid rubber. You have to remember that you will loose any warranty that you have on the shingles. With shingles you should have a well ventilated attic if not you can have problems on your roof in the future. With this product your shingles will not be able to breathe and with heat condensation may form. This can cause problems in the future.

          It a great solution for what we needed
          We where having some horrible issues of leaking all over the house and we decided to go with this primer. Ordered it online and picked up at the store, it arrived ahead of time which was great. It applied real easily, gave it two coats and it covered all the micro cracks. Really adhered to the concrete. We then added the Acrylic Urethane Elastomeric White Reflective Roof Sealer from the same brand 24hrs apart and let it cure for 48hrs as described. The following day he had hard rains & 0% leaks.

            As an experienced licensed General Contractor. I can honestly say that all of the Lanco products are outstanding and perform far better than I ever expected. I primarily use a combination of the Aqua-Proof and the Urethanizer to properly seal metal building roofs.
