Question 1

How can I know this product will last?

Accepted Answer

A high-quality nanotechnology roofing sealant typically lasts 5–10 years, depending on the roof's condition, climate, and surface preparation. Unlike traditional coatings that sit on top, nano-tech sealants bond at the microscopic level to the roofing material, creating a protective barrier that repels water, UV rays and dirt.

Question 2

Will you repair the roof before application?

Accepted Answer

Yes. We perform all required repairs — replacing missing, broken or loose shingles — before any sealant goes on. Prep is non-negotiable.

Question 3

What about when I do need a full replacement?

Accepted Answer

After we coat your roof, we re-inspect it every 1–2 years to keep it in great condition. If Tech Barrier previously coated your roof, we offer a 7% discount on a full replacement, no questions asked. The discounted estimate is locked in on the day of your initial coating.

Question 4

Does this product change the appearance of my roof?

Accepted Answer

Yes — for the better. TechBarrier sealants re-oil your shingles giving them more vibrant hues without changing the color.

Question 5

Do I need to clean my roof beforehand?

Accepted Answer

Soft washing is required when there is heavy algae or moss growth. In other cases, we wash for aesthetic reasons — surface dirt does not affect performance. Once Tech Barrier is applied, soft washing will no longer effectively remove stains.

Question 6

Why is this a good investment?

Accepted Answer

Compared to a full replacement (often many times the cost), nano-sealant extends the life of your existing roof at a fraction of the price, delays a future replacement, reduces landfill waste, resists algae and moss, and protects against UV and weather damage for up to 10 additional years.
