The rooftop's flashing system is a necessary component that prevents water damage from seeping into the sensitive spaces that are not protected by the roof's shingles. Flashings are typically made from all types of materials ranging from alloys to synthetic systems. Though it is critical to choose the right material to match the home's environment, it is also equally important for Rural Hall roofing experts to select the appropriate sealant for the flashings to ensure that they are secured well enough to perform without any type of incident. By learning more about the different types of sealants used, homeowners can plan ahead for their installation and get the most out of their roofing service.

One of the most common systems used is butyl. It is a synthetic rubber polymer that is utilized in a variety of construction industries because of its durability and adaptability. It comes available in a tube form for easier applications in tight places or as a tape roll that experts can apply as necessary. Not only is it one of the most economical choices available, but it can also be ideal for simpler rooftop applications in warmer environments. However, butyl is not good for larger applications, such as where joints need to be protected, as the material is uncured and does not adhere well when it's left overexposed.

Polyurethanes are another popular sealing material. These are especially critical for joining together flashing laps, and many contractors use them in various masonry applications, making them one of the most popular choices for cementitious tiles. Polyurethanes are able to last upwards of 10 years, which makes them ideal for asphalt shingle systems that may share the same longevity. Contractors have more freedom when it comes to working with this material as the sealant has a tack-free time of approximately 4 hours, and the curing depends on the type of polyurethanes used during the installation process.

Modified polyethers are newer materials that are used in many modern roofing applications. They share the positive characteristics of silicone and polyurethanes, which makes them a particularly versatile and desirable choice for all types of flashing applications. Polyethers also do not migrate oils into porous masonry, making them perfect for homes that feature extensive stonework. Polyethers have a relatively quick tack-free time, and this material is also able to adhere to all types of substrates and membranes, allowing it to stand up to a variety of weather conditions.
