Tallahassee Roofing: Article About Roofing Sealants and Adhesives
Many roofs are a mixture of shingles and nails, but other materials involved aren't as obvious to the novice eye. Contractors use a host of different coatings, sealants and adhesives to bond roofing materials perfectly to a structure. When Tallahassee roofing professionals visit a property for a maintenance appointment, they can explain all the various substances they use to create a waterproof rooftop surface.
When a roof is first installed, contractors have an opportunity to waterproof beneath the shingles. Experts can place thermoplastic polyolefin (TPO) underneath shingles to give a roof its final layer of protection. After the roof is installed, a relatively common sealant is waterproofing. These sealants are either sprayed or brushed along a surface to form a barrier to moisture. A variation on this sealant is algae and moss protection. On particularly moist roof sections, algae and moss can grow almost year round. Select sealants prevent moisture from adhering to roofing materials, creating an inhospitable area for algae growth. Roofs remain a uniform color without green patches popping up during rainy seasons.
Contractors don't use caulk extensively on exposed roof areas because it can break down. However, caulk is used in small, hidden gaps across the roof. Even the smallest crack can provide a pathway for rainwater into the home. Caulk applied with a caulk gun fills these sheltered areas and remains strong when not exposed to sunlight and weathering.

Roofers choose industrial strength caulk for their purposes, unlike common caulk products used for bathrooms and other interior applications.
Roofing cement is commonly used on rooftops because of its resilience to wear. Contractors apply roofing cement to tiny shingle fractures and exposed nail heads, for instance. This coating dries into a long lasting barrier to moisture and high wind damage. When a shingle has a small tear, roofing cement creates the bond necessary to preserve that material without needing to replace it entirely.
Shingles don't usually require adhesives because nails hold them tight, but high wind regions could dictate their use. Contractors apply adhesive under loose shingle ends to avoid curling and other wind damage. Adhesives are more common under flat or low slope membrane system installations. This roll roofing requires adhesives to hold the layer securely against the building for years of moisture and sunlight protection.
Even when a particular sealant is necessary, there are many variations on one product alone. From polyurethane to silicone coating types, contractors select the right substance for each unique project. Their experience dictates which coating works best to ensure a long lasting rooftop with little or no leaks over the years.
