Commercial roof coating is a great value for many reasons.
Don’t replace your commercial roof when an acrylic or silicone roof coating will do a better job, for a fraction of the price.
Both systems have many benefits. Each:
- costs significantly less than a roof replacement,
- protects your roof from harmful UV rays,
- is quickly and easily installed,
- is highly durable,
- is environmentally friendly, and
- will limit the expansion and contraction cycles that lead to roof degradation.

A Comparison of Acrylic and Silicone Roof Coating
Acrylic coatings offer an excellent balance of cost and performance.
This water-based solution is a cost-effective alternative to roof replacement.Strengths
Acrylic roof coating has many upsides including:- exceptional durability,
- more forgiving of roof substrate,
- relatively easy to install,
- cost-effective,
- withstands heavier foot traffic,
- and dirt doesn’t accumulate on them so they maintain their reflectivity.
Weaknesses
Acrylic roof coatings have some downsides including:- They lose mil thickness due to weathering, as evidenced by the chalky residue that builds up over time.
- They can take significantly longer to install than silicone.
- They usually don’t perform well in ponding water, which is why we use Astec coatings. Astec coatings actually provide a warranty against ponding water when applied at a sufficient thickness.
Workers install acrylic roof coating over an existing single-ply roof.
Silicone coatings have a reputation as the “Cadillac” of roof coating systems.
Strengths
These coatings are stable, flexible, and can come with a twenty-year warranty. Silicone coating has numerous strengthens including:- they are exceptionally durable,
- they don’t degrade from weather, and lose mils,
- they don’t get hard or brittle,
- rapid installation,
- they work well in ponding water if the water stays for less than 48 hours,
- they conduct heat poorly,
- they are easy to apply. Just power wash, prime if needed(rarely), and apply coating.
- they are moisture-cured, so humidity can even promote their cure.
Weaknesses
Silicone roof coatings have some downsides.- They need a stable substrate to bond too.
- They require a bleed block if applied to an asphalt roof.
- They are significantly more expensive than acrylic coating. This is offset by the need for fewer coats.
- They may pull away from edges and curl.
- They are very slippery when wet so shouldn’t be applied if maintenance people are going to access the roof.
- They don’t hold up well against foot traffic.
- They hold dirt, so they lose reflectivity over time.
- They are harder to re-coat because they are almost as slippery as Teflon.
- Removal can be difficult, because they are very stubborn.
- They can be easily torn so they are installed with a fabric that compensates for their mechanical weakness.
