Question 1

How long does a roof coating last?

Accepted Answer

A properly applied silicone roof coating typically lasts 10-15 years before needing reapplication. The beauty of coatings is that they can be recoated again without a tear-off, making them a long-term maintenance strategy for commercial and low-slope roofs.

Question 2

Is roof coating cheaper than replacement?

Accepted Answer

In most cases, yes. Coating costs a fraction of a full replacement and can be done in less time with less disruption. That said, coating only works when the underlying structure is sound. If your decking is rotted or your roof has severe damage, replacement is the right call.

Question 3

Can you coat a shingle roof?

Accepted Answer

Roof coatings are primarily designed for flat, low-slope, metal, and modified bitumen roofs. Traditional steep-slope asphalt shingle roofs are generally better served by repair or replacement. We'll inspect your roof and recommend the right approach.

Question 4

Silicone or acrylic roof coating: which is better in Iowa?

Accepted Answer

Silicone and acrylic coatings fit different roof conditions. Acrylic systems perform best where the roof has positive drainage, while prolonged ponding water can shorten their service life or affect warranty eligibility. Silicone is often the better fit for areas that hold water. We select the system from the existing membrane, drainage, preparation needs, and the manufacturer's written specification rather than climate alone.

Question 5

Do you coat metal roofs?

Accepted Answer

Yes. Metal roof restoration is one of the best uses for a coating. Aging metal panels often develop problems at fasteners and seams before the panel itself fails. After loose material and corrosion are properly prepared, a compatible coating system can seal seams and fastener heads, slow further corrosion, and add a reflective surface. Whether restoration is appropriate depends on the panel and deck condition.

Question 6

Is a roof coating the same as waterproofing?

Accepted Answer

A properly specified coating can form a continuous weather-resistant membrane, but it is not a fix for structural problems or unsuitable underlying materials. It cannot repair wet insulation, rotted decking, or a failed substrate. We assess drainage, adhesion, visible conditions, and the existing roof assembly before quoting a coating; if moisture is trapped below the membrane, restoration may not be appropriate.

Question 7

What does a roof coating cost, and where in Iowa do you apply them?

Accepted Answer

Coating cost depends on square footage, the number of penetrations, how much prep and seam work the roof needs, and the system we specify. That is why we quote from an inspection rather than a phone call. We apply coatings across Central Iowa, including Des Moines, West Des Moines, Ankeny, Urbandale, Waukee, Grimes, Altoona, and the surrounding communities. Most of this work is commercial and low-slope, so call (515) 967-8199 and we will get on the roof and give you real numbers.
