Felt Roofing
Your roof is an important aspect of your house that you need to know about in order to maintain it the right way. Felt roofing is the solid material that lines the roof between your house and the final layer of your roof. The roofing material protects the wood sheathing from heavy downpours of rain and snow. There are three major types of felt roofing underlayment: asphalt-saturated felt, rubberized asphalt, and non-bitumen synthetic underlayment. Roof felting is what keeps your roof from being destroyed by harsh weather, storms, tropical climates and other hostile natural events.
Benefits of Felt Roofing Felt roofing is used widely because of the protection it offers not only to the roof but the occupants of the house as well. Some of its major qualities are its ability to repel water, provide protection against hailstone, storm, snow, and other natural hazards and also its ability to withstand harsh temperatures. Asphalt-Saturated Felt Asphalt-saturated felt is an underlayment material that improves the durability of the roof deck and protects it against large tree branches, hailstones and debris. The first type of underlayment created was the asphalt-saturated felt, which is the reason it was commonly called underlayment. Asphalt-saturated felt has a very similar quality to tar paper but is much more durable due to the natural plant fiber. This type of underlayment is applied all over the roof deck and also flooded with asphalt in order for the roof to be water resistant. Rubberized Asphalt Rubberized asphalt has a lot of qualities such as water resistance, durability, sound absorption, and fiberglass reinforcement. These qualities are offered by the manufacturer in different ways in accordance with the requirement of the roof. It has very little to no asphalt in its constituents and feels more like rubber sheets. It can tolerate any degree of temperature which eliminates common roof problems like substrate movement and also makes it a suitable choice of underlayment for hotter regions. It is also installed with the use of adhesives instead of the usual roofing nails. When the roof is punctured it can be repaired or patched while the outer roofing layer is replaced or partially removed. The use of adhesives in its installation prevents leakage even in the unlikely event of a puncture. Non-Bitumen Synthetic Underlayment This type of underlayment is the most preferred type of among many home owners and professionals today because of its strength, resistance against fungal growth, water resistance efficiency and elasticity. It is made from plastics like polypropylene and other types of food container plastics. Its ability to hinder fungal growth prevents the growth of mold and mildew on the substrate. Non-bitumen synthetic underlayment is sometimes combined with waterproofing materials to make it even more durable. The underlayment is applied across the entire roof and saturated in asphalt and sometimes fiberglass to make it stable and resistant to tear. |
