Roof Coating vs Replacement in Arizona: Which Is Right for Your Roof?
Key Takeaways
- Reflective coatings can lower roof surface heat and protect worn flat roofs.
- Coatings do not fix wet insulation, soft decks or structural damage.
- Ask for a moisture and condition check before choosing a coating.
Roof coatings are popular in Arizona because they reflect heat and add a protective layer. They are not a cure-all, and the right choice depends on what is under the surface.
What a Roof Coating Does
- Reflects sunlight and reduces surface heat.
- Seals small cracks and seams.
- Adds a protective layer against UV and weather.
- Can extend the life of a sound roof.
When Coating Makes Sense
| Situation | Coating? |
|---|---|
| Dry roof, light wear | Often a good fit |
| Minor cracks and seams | Repair first, then coat |
| Wet insulation or soft deck | Replacement is more likely |
| Active leaks | Fix the leak before coating |
| Tile or shingle roof | Usually not the right product |
