Question 1

How long does a commercial roof coating last in Houston?

Accepted Answer

Most commercial roof coatings in Houston last 10 to 20 years. Lifespan depends on the coating type, the applied mil thickness and the quality of surface prep. Regular inspections help it last longer. Because the system is recoatable, a fresh layer can extend its life again before the first coating wears through.

Question 2

Can you put a roof coating over TPO roofing?

Accepted Answer

Yes, aging TPO roofing is often a strong coating candidate. The membrane must be well attached and mostly dry. First, crews clean the surface, repair seams and apply a primer made for single-ply roofs. Then they apply silicone or another compatible coating at the manufacturer's specified mil thickness.

Question 3

Is silicone or acrylic roof coating better for Houston flat roofs?

Accepted Answer

Silicone is usually better for flat roofs that hold water after Houston storms. It resists ponding and UV breakdown. Acrylic roof coating suits metal and well-drained low-slope roofs instead. Before choosing either product, a Houston roofing company should run adhesion tests on your actual roof surface.

Question 4

Will a roof coating fix ponding water on my flat roof?

Accepted Answer

No, a silicone coating protects the membrane under ponding water, but it does not remove the water. Drainage issues should also be corrected. Clearing drains, adding crickets or installing tapered insulation may be needed. Those steps protect the roof deck and help your new coating perform well for longer.

Question 5

Can my business stay open during a roof coating project?

Accepted Answer

Yes, most businesses stay open during a coating project. Crews work on the roof, so offices, stores, clinics and restaurants keep operating below. Unlike a tear-off, there is little noise, odor or debris. We plan work zones, access points and schedules around your hours to limit disruption for tenants and customers.

Question 6

Do commercial roof coatings come with roof warranties?

Accepted Answer

Yes, many coating systems qualify for manufacturer roof warranties and contractor workmanship coverage. Terms depend on the product, mil thickness and roof condition. A clear written warranty spells out exactly what is covered. Pairing it with a maintenance and repair plan also helps keep your coverage active.

Question 7

How do roof coatings hold up to hurricanes and hail in Houston?

Accepted Answer

Properly installed coatings handle Houston storms well when the roof below is sound. They seal the seams that wind-driven rain often exploits. Thicker coats and fabric-reinforced details add impact resistance against hail. After any major storm, schedule a roof inspection to catch hidden damage early and keep coverage intact.

Question 8

Does a cool roof coating really keep a building cooler?

Accepted Answer

Yes, a cool roof coating reflects sunlight and releases absorbed heat. As a result, the roof surface and the spaces below stay cooler. HVAC units also work less during long, humid Houston summers. Look for coatings rated by the Cool Roof Rating Council for independently tested reflectance and emittance.

Question 9

How do I know if my roof needs replacement instead of a coating?

Accepted Answer

You likely need a replacement if insulation is widely wet or the roof deck is damaged. Severe blistering or failing seams across the whole roof are also red flags. A moisture survey and core samples give a clear, reliable answer. For roofs in this condition, commercial roof repair or replacement comes first.

Question 10

How does TPO roof cost in Houston compare with a roof coating?

Accepted Answer

A coating usually costs less than a new TPO roof because it avoids tear-off and disposal. TPO roof cost in Houston depends on roof size, insulation, access and code requirements. Coating cost depends on prep, repairs and thickness. An inspection shows which option offers better long-term value for your building and budget.
