Pittsburgh Shingle Roof Coating Contractor

The best coating for asphalt shingles is one the shingle maker and the coating maker both support, on shingles that are still in service. We inspect attachment, wear, and flashing first. A product sold for every kind of roof is no proof it suits your particular shingle.

Flashing that is failing gets repaired even if the church shingles look good and a coating is approved. We inspect the roof-to-wall joints and penetrations before talking about the surface. The leak repair is priced as its own item, since a coating laid over bad flashing leaves the leak in place.

Curled shingles at commercial eaves are evaluated for repair or replacement before coating comes up. We check attachment and how far the wear runs, including whether the shingles still shed water. Coating leaves curled tabs curled, even when the product is rated for asphalt shingles.

Coating over shingles works only on serviceable shingles where both makers allow it. Many commercial buildings have shingles only on a mansard or entry roof, which often makes a good candidate. Steeper, worn-out sections are usually better reshingled.

It can. Some shingle makers void coverage when a coating is applied, and others allow approved products. We ask you for the shingle details and check the maker position before recommending any coating.

Life depends on the shingles under it, the product, and the upkeep. A coating on flat, attached shingles with only granule wear holds up far better than one laid over aging tabs. We tell you what we see and which product the makers support, instead of naming a set number of years.

Most mansard faces are reached from a lift parked at the building edge, which keeps the sidewalk mostly open. Taller or crowded faces can need scaffolding along part of the wall, and we plan that with you and the municipality where the sidewalk is involved.
