Anderson Silicone Roof Coating Contractor

It falls within our published coating range of about $2.50 to $4.00 per square foot, while replacement runs about $5 to $8. Where your warehouse lands depends on coating thickness, the number of coats, screw and lap prep, how much area ponds, and how easy the roof is to reach.

Silicone picks up more dirt than acrylic, which dulls its brightness over time, and it is slippery when wet. Few other coatings stick to it, so recoats are usually silicone again. It also costs more per gallon. On flat or low-slope Anderson roofs, its water resistance usually outweighs those points.

On a dry day inside the maker limits, yes. Silicone tolerates cooler temperatures than water-based coatings, but frost, morning dew, and wet days all push work back. We check surface temperature, dew point, and the overnight forecast before the sprayer starts.

Water that sits under silicone still adds weight, holds debris, and can point to a sagging deck. Clearing outlets and checking the structure first keeps the coating from covering a problem that keeps growing underneath.

In many cases, after cleaning and an adhesion test. The old acrylic has to be firmly attached, and a primer often goes between the two. Peeling acrylic is scraped back to a firm edge before the silicone goes on.

Most jobs use one or two passes to reach the thickness the maker specifies, with an extra pass at details. The reading matters more than the count, so crews check wet-film thickness as they spray and add material where a section comes up short.
