Yes, you need to install an underlayment of asphalt-saturated felt before installing rolled roofing.

The cost of installing rolled roofing averages about $100 per square depending on the size of the roof and the materials, you can expect to pay that for materials and labor.

1. Poor Durability: Rolled roofing is made from thin and lightweight materials, making it less durable than other types of roofing. This can lead to more frequent repairs and replacements, resulting in increased costs over time.

2. Limited Lifespan: The expected lifespan of rolled roofing is much shorter than other types of roofing, typically lasting between 5 and 10 years. This means that homeowners will need to replace their rolled roof more often, which can become expensive.

3. Leaks: The lightweight and thin material in rolled roofing can be easily punctured or torn, leading to leaks. This can be especially problematic in areas with harsh weather or heavy snowfall.

4. Unattractive Appearance: Rolled roofing is not very attractive and can detract from the overall aesthetic of a home. It also requires a professional installation, which can be expensive and time-consuming.

5. Fire Risk: Rolled roofing is made from petroleum-based materials, making it more flammable than other types of roofing. This can create a fire hazard, especially in areas with high temperatures.”

It is generally not recommended to install rolled roofing over existing shingles. While it may be possible to do so, it can lead to several issues that may compromise the integrity and effectiveness of the roofing system.

Here are some reasons why it is not advisable to install rolled roofing over shingles:

• Added weight: Installing a new layer of roofing material over existing shingles will add extra weight to the roof structure. This can cause the roof to become overloaded and potentially lead to structural damage.
• Uneven surface: Shingles may have different heights due to wear and tear, and this can cause the surface to be uneven. This can make it difficult for the rolled roofing to lay flat and adhere properly, which can lead to leaks.
• Trapped moisture: Moisture can become trapped between the shingles and the rolled roofing, which can lead to mold growth and rot.
• Reduced lifespan: Installing a new layer of roofing material over old shingles can reduce the lifespan of the new roof. This is because the new roof will not be able to breathe properly and may be more susceptible to damage from weather and other external factors.
• In general, it is recommended to remove the old shingles before installing rolled roofing. This will provide a clean surface for the new roofing material to adhere to, which will improve its lifespan and effectiveness.

Asphalt Shingles are generally better than roll roofing because they offer better protection, better insulation, and they look better. They also last longer, require less maintenance, and are easier and cheaper to install.

No, nails are not used on rolled roofing. Instead, rolled roofing is secured with roofing cement applied to a surface that has been cleaned and primed to adhere better.

The minimum recommended slope for rolled roofing is 1/4 inch per foot (2.3 cm per m) considered to be 2:12, or 2 inches of vertical rise for every 12 inches of horizontal run. This means that for a roof to be suitable for rolled roofing, it must have a minimum slope of 9.5 degrees.

The number of layers of rolled roofing that can be installed on a roof can vary depending on local building codes and manufacturer specifications. In general, however, it is not recommended to install more than two or three layers of rolled roofing.

Roll roofing is typically cheaper than shingles, however shingles may be a better choice if you are looking for a roofing material that is more durable and long-lasting.

The best roll roofing depends on the specific needs of a project. Generally, the most popular roll roofing materials are asphalt roll roofing, fiberglass roll roofing, rubber roll roofing, and plastic roll roofing. Asphalt roll roofing is the most common, cost-effective, and durable option. Fiberglass roll roofing is also a popular choice, as it is lightweight and resistant to fire. Rubber roll roofing is water-resistant and can last up to 50 years, but it is more expensive than other options. Plastic roll roofing is the least expensive option, but it is not as durable or long-lasting as the other materials.

Peel and stick roll roofing typically lasts between 10 and 15 years, depending on how it is installed and maintained.
