Did you know that putting a new roof over old shingles can save up to 25%? This is because you don’t have to pay for removing the old roof and buying new felt paper. Many people are now looking into using spray foam (SPF) over their old shingles. This is especially true for composite shingles.

When foam is applied right over good shingles, it can make your roof last longer. It also makes your roof better at keeping warm air in and cold air out. Plus, it meets the standards set by the Spray Polyurethane Foam Alliance (SPFA).

This method helps protect your shingles by not tearing them off. It works best if your shingles are not too old or brittle. Any loose shingles should be fixed before adding the foam. If done right, this foam roof can last as long as a full roof replacement.

Key Takeaways

• Installing foam over shingles can save on removal and labor costs.
• Foam roofing can make your shingle roof last longer if done correctly.
• Following SPFA guidelines is key for a good and compliant system.
• Foam roofs need to be recoated every 15 years.
• It’s important to make sure your shingles are stable before adding foam.

Benefits of Foam Roofing Over Shingles

Foam roofing offers many benefits for both commercial and residential buildings. One key advantage is its energy efficiency. It provides better insulation, which can lead to big savings on energy bills. This is because foam roofing has a high R-value, which helps keep buildings cooler in summer and warmer in winter.

Another great thing about foam roofing is that it can be renewed. After the warranty ends, you can recoat the roof without tearing it down. This costs less than replacing a traditional roof, saving money in the long run.

Foam roofs also have no seams, which are common leak points in other roofs. This makes them watertight, reducing the chance of leaks and water damage. Each hole in a foam roof is sealed well, making it strong and leak-free.

Thinking about the environment? Foam roofing is good for the planet. It often doesn’t need much of the old roof to be removed, saving money and the environment. Plus, it doesn’t release many harmful chemicals into the air.

Structurally, foam roofing is also a strong choice. It can hold a lot of weight, making it durable. The installation process also creates little waste, making it a green option for building. Overall, foam roofing is a smart choice for many reasons.

Foam Roofing Installation Process

The foam roofing installation starts with checking the roof’s condition. It must be dry, clean, and strong. This first step is key for a good job.

Before applying foam, the roof needs to be free of dirt and debris. Sometimes, it needs a power wash. Also, the roof’s structure must be solid. This is especially true for older roofs that might need extra support.

Thinking about upgrading to a shingle roof? Spray foam is a top choice for insulation. It saves a lot on energy costs. Spray foam has a high R-value, unlike shingle roofs which have none.

After applying foam, it needs protection from the sun. A silicone coating is added for this.

Installing spray foam roofing requires special skills and knowledge. Contractors spend a lot of time learning. It’s also important to check warranties with contractors, as they vary.

In short, the foam roofing process is detailed and important. It makes a great choice for upgrading your roof.

Can You Put a Foam Roof Over Shingles?

Many homeowners ask if you can put a foam roof over shingles. The answer is yes, but with some conditions. Installing foam roofing over shingles can save money and be practical. But, you must check the legal and structural needs first.

Local building codes are key in deciding if you can do this. You can’t put foam over more than two layers of roofing. The roof must also be clean, dry, and well-attached to the structure. If there are loose shingles or damage, you might need to fix or remove them first.

Foam roofing has many benefits. It’s good for insulation, saves money, and is eco-friendly. Adding foam to your roof can save thousands of dollars, especially for complex roofs. It’s cheaper upfront and saves on energy costs over time.

Also, foam roofs help keep your home warm in winter. Spray foam insulation keeps heat in and prevents leaks. Make sure to install it in the right order for the best results.

When using materials like Thermoplastic polyolefin (TPO), you need to follow extra steps. Each material has its own needs for foam application. So, it’s wise to talk to a roofing expert for advice that fits your situation.

In conclusion, a foam roof is a durable and energy-saving choice. It can go over shingles if you follow the rules and prepare well. It’s a great option for saving money and keeping your home warm.
