Types of Roof Cracks
Hairline Cracks
Hairline cracks are thin, superficial cracks that typically appear on roofs exposed to extreme temperature fluctuations. These cracks are generally not a cause for concern and can be easily sealed with a roof crack repair coating.
Transverse Cracks
Transverse cracks are perpendicular to the roof’s ridges. They can be caused by structural movement or improper roof installation. If left untreated, these cracks can allow water to penetrate the roof and cause damage.
Alligator Cracks
Alligator cracks resemble the pattern of an alligator’s skin. They are caused by prolonged exposure to the sun and moisture. Alligator cracks compromise the roof’s integrity and require prompt repair with a roof crack repair coating to prevent leaks.
Choosing the Right Roof Crack Repair Coating
The type of roof crack repair coating you choose depends on the size, depth, and location of the crack.
Acrylic Coatings
Acrylic coatings are water-based and offer excellent flexibility. They are ideal for sealing hairline cracks and minor transverse cracks.
Silicone Coatings
Silicone coatings are highly durable and resistant to moisture. They are suitable for repairing larger cracks and alligator cracks.
Elastomeric Coatings
Elastomeric coatings are extremely elastic and can accommodate roof movement. They are ideal for sealing cracks in areas with extreme temperature fluctuations.
