While the underlayment of your metal roofing system is not visible, it helps protect your home from water and moisture damage. Generally, two subfloors are used when installing metal roofing in a home. Miami roofers will tell you why metal roofing will prevent moisture from damaging your deck and attic.

Why roof underlayment is essential

The subfloor protects the roof by:

• Providing deck water protection
• Providing a "slip sheet" for metal to move on the roof deck due to expansion and contraction.
• Shielding from teat from the sun that can overheat metal roofs

The right underlayment will keep your home in great condition for a lifetime if installed correctly, Always contact the best roofing company in Miami.

Variety in subfloors

• Rubber Coated Asphalt - Rubber Coated Asphalt is fully waterproof. Since it has a higher polymer content than rubber and asphalt on their own. This is the correct type of product most suitable for all metal roof installations.

• Synthetic underlayments: Thanks to the multiple layers of polypropylene, it provides high-tech performance. Those with mesh reinforcement offer greater tear resistance. They must also include a safe and non-slip surface so that there are no accidents when walking on it.

•  Nylon Mesh: Typically used where there is a heated roof system in conjunction with closed-cell foam insulation. 

Keep in mind that not all subfloors are used in every home. Consult your contractor on which one is best for your home's roof and ventilation system.
