1.Product Features

What is fiberglass roofing mat? Fiberglass roofing mat is a durable, stable, and waterproof reinforcement material widely used in roof waterproofing and asphalt shingle production, enhancing the overall performance and lifespan of roofing systems.Its core characteristics are as follows:

High-strength fiberglass base material: Excellent tensile and tear resistance.

Weather-resistant: Stable performance under long-term exposure to sunlight, rain, and temperature fluctuations.

Dimensionally stable: Resists shrinkage or expansion with temperature fluctuations, reducing the risk of roof deformation.

Waterproof: Bonds firmly with asphalt and other waterproofing materials to form a highly effective waterproof layer.

Easy to process: Compatible with a variety of waterproofing systems, suitable for cutting and installation.

2.Advantages

Extended roof life: Effectively prevents cracks and water seepage.

Adaptable: Suitable for different climate zones and building structures.

Easy to install: Lightweight, easy to transport and install.

Economical and practical: Moderately priced and highly cost-effective.

3.Application Scenarios

Asphalt Shingle Reinforcement

Waterproofing Membrane Base

Flat and Sloped Roof Waterproofing Systems

Landscape Roofing and Roof Garden Anti-seepage Treatment

4.Selection Guide

Weight (gsm): Select a felt weight appropriate for the roof structure and load-bearing requirements.

Weather Resistance Rating: For long-term outdoor use, a high weather resistance rating is recommended.

Bonding Material: Ensure good adhesion with waterproofing materials such as asphalt and polymer.

Construction Environment: Consider the need for reinforcement based on construction temperature, humidity, and equipment conditions.

5.FAQs

Can fiberglass roofing mat be used on its own without any coating?

Not recommended. Roofing felt is generally used as a reinforcement layer for waterproofing membranes or asphalt shingles and is most effective when used in conjunction with waterproofing materials.

Is roofing mat waterproof?

Fiberglass itself does not absorb water, but it must be well bonded to the waterproofing layer to prevent water seepage.

What is the lifespan of roofing mat?

If properly installed and combined with high-quality waterproofing materials, fiberglass roofing felt can last 20–30 years or even longer.

6.Summary

Due to its excellent waterproofing, weather resistance, and dimensional stability, fiberglass roofing mat is a core reinforcement material in roofing waterproofing systems. Proper selection and proper installation can significantly extend the lifespan and durability of your roof.
