In this guide, we look at the constituents of roofing felt and the different types available on the market. You’ll also learn the benefits of roofing felt.

That said, let’s get started!

What is Roofing Felt?

Roofing felt is an ancient roofing system that keeps flat roofs waterproof. Also known as roofing belt underlayment or roll roofing, roofing felt is a protection layer installed between the deck and the roofing shingles.

Roofing felt’s one side comes coated with a mineral to protect the felt from sunlight and weather damage. Besides, the roofing material is available in different sizes, though commonly sold in 1m x 10m rolls.

What is Roofing Felt Made of?

Most of the current roofing felt consists mainly of improved bitumen mixed with either fibreglass or polyester. However, Roof Master & Construction experts recommend the latter since it is tough to tear. It also copes well with the usual movement on flat roofs.

While the roofing felt can form a strong roof, it needs a final layer to safeguard it from the elements. Although extreme cold comes with a negative impact on felt roofing, direct sunlight proves its biggest enemy. It dries out the oils in the system, making it weak, and can cause heat expansion movement too.

You can lessen these hitches by adding a surface protection layer. Some of the different final protective coatings include lead flashings and labour-intensive solar reflective paint. However, a mineralized cap sheet gives you a striking maintenance-free finish.

5 Types of Roofing Felt

There are various types of roofing felt to consider in your roofing project. Multiple factors may influence your judgment, including whether you are installing the roof yourself and the size of your project. Some of the roofing felt includes the following.

1. Torch-on Felt

Torch-on felt is a hard-wearing substitute to other types of roofing felt. It is commonly applied on garage and extension roofs. The torch-on felt sees three layers of bitumen felt melt-welded onto the top with a blow torch, creating a waterproof seal.

As the name suggests, torch-on felt requires a gas torch during the application process. Also, you can combine the gas torch with an underlay or lie in a single layer. Despite being an expensive option, torch-on felt offers a long-lasting finish.

2. Fibre-based Felt

You can use less-costly fibre-based felt on garden sheds and wooden outbuildings. This type of roofing felt can also work as a single option or combined with an underlay sheet. It’s also vital to use roofing nails or roofing felt adhesive to attach the fibre-based felt.

3. Polyester Felt

Polyester felt works best in garages and extensions. The roofing felt option requires handling and fixing like a fibre roofing felt using one layer of underlay and hot bitumen or cold adhesive.

4. Glass Fiber Felt

Though commonly used on extensions and garages, glass fibre works better on garden sheds. The roofing felt is expensive but lasts longer than the cheaper options.

It would help if you combined the glass fibre felt with either one or two layers of underlays. However, you may require to add a third layer when using it for roofing an extension of your home. It is applied using either cold felt adhesive or hot bitumen.

5. Self-adhesive Felt

Self-adhesive felt is an ideal option for a DIY project. It permits the roof covering to get laid without the need for naked flames. If you are planning to install the roofing felt by yourself, then this is your solid choice.

The roof felt self-bond to the substrate once the release film gets peeled off the bottom. That makes it an ideal covering for small projects such as porches, flat roofs, and garages. In addition, the roofing solution is tough, durable, and cost-effective.

Reasons Why You Should Use Roofing Felt

Adding a protection layer between your structural roof decking and your roof shingles helps create a gorgeous and durable roof. Among the reasons why you should use roofing felt include the following.

1. Provides Additional Protection Against Weather

Shingles act as your roof’s first line of defense against elements. However, having a backup layer of weather protection beneath helps prolong the life of your roof. If a significant weather incident breaks your shingles loose, the roofing felt safeguards your woodwork against rain until you replace the shingles.

2. Improves Look and Uniformity

Sometimes roof decks fail to lie perfectly straight or flat. Using roofing felt gives an even, uniform surface upon which you can install your shingles. Also, it can help thwart the picture framing effect or the pattern of your wood decking via your shingles by offering an added layer on top of uneven wood.

3. Prevents Wood Resin Stains

When you use particular types of wood to build your roof, there is sometimes a risk the timber will leach a small amount of resin over time as it ages. Therefore, having a layer of roof felt blocks the resin, stopping it from staining or compromising your roof shingle.

4. Durability

A good roof stands the test of time, whether experiencing high levels of foot traffic or very little. Roofing felt is a durable option that holds up well to UV rays and extreme heat during hot seasons of the year.

Provides Backup Protection Against Ice or Water Damage

Ice or snow dams are common causes of residential water damage. Sometimes the heat from your house melts snow or ice on your roof. As a result, the water is likely to leak into your roof’s corners and openings and eventually into your home, causing damage to ceilings, walls, or insulation.

The most significant protection against ice and snow dams is a protection membrane seal around the shanks of the roof clasps for a leak-resistant fit. Also, roofing felt offers extra protection against leakages, hence offering an extra layer of water resistance.

Final Words

The first thing to consider when opting for roofing felt is the directions on your final roofing material. Also, once you understand what roofing felt is made of, always hire a professional roofing contractor who guarantees you the best work worth your money.

5 Tips for Making Home Roof Repairs

5 Tips for Making Home Roof Repairs

Your roof performs several vital functions to keep your home safe and comfortable. It keeps hot and cold air in your home, prevents rain and other precipitation from entering, and so much more.

As such, roofing issues can many other problems. Leaks can cause water buildup. Openings can lead to cold or hot air escaping the house, increasing your AC bill.

Because of this, dealing with roofing issues is essential to keeping your home safe and secure. To help you with this, we’ve compiled five essential tips for handling home roof repairs. We hope this article gives you the help you need!

1. Shingle Replacement

One of the most common problems in domestic roofs is loose or missing shingles. Shingle problems usually occur as a result of long-term weathering. Rain, snow, hail, and even strong winds all wear down your asphalt shingles.

Moreover, this weathering affects the adhesives and nails that hold the shingles down. When those shingles come loose, the layers of your roof underneath those shingles become vulnerable.

If all you’re facing is fixing a few loose shingles, all you have to do is take some adhesives and nails onto your roof. Put the adhesive down beneath the shingles, then nail down the loose shingles and the shingles around it.

2. Keep Your Gutters Clean

This is a preventative measure in making sure your roof doesn’t get compromised. Clogged gutters aren’t just an aesthetic flaw; they are a common cause of water buildup on the roof.

Water buildup wears down the structural integrity of your roof in places and causes leaks in the home. This can lead to expensive repairs further down the road. Avoid that problem by cleaning out your gutters.

3. Inspect Your Roof’s Valleys

The valleys (or ridges, as they’re sometimes known) of your roof are the place where two sides of your roof intersect. These are the places where rainwater will pool up after rain.

As said before in the gutters section, water buildup on your roof often leads to leaks and further damage. Inspecting the valleys can prevent that buildup from occurring.

4. Hammer Nails In Completely

Whether you’re trying to fix shingles or the flashing beneath them, you’re going to have to hammer down some materials on your roof. When you do, make sure to drive them in completely.

If you leave nail heads exposed, it is much easier for those nails to become loose. This will leave your shingles more vulnerable to wind and other weathering.

5. Take Proper Safety Precautions When Doing Home Roof Repairs

When making roof repairs, make sure you take the proper safety measures. Wear rubber-soled shoes for good grip and traction on the roof, along with safety goggles for dealing with nails and debris.

Know When to Call Professionals

There are many things you can do yourself for home roof repairs. However, some problems go much deeper than a DIY project. When that happens, it’s best to call a professional service; learn more here about hiring a roofing contractor.

How to Tell If You Need a Roof Replacement

Are you wondering whether or not you need a new roof?

Check Your Attic

Sometimes, the first signs of damage to your roof don’t come from the outside. Rather, they’re most noticeable from the inside of your attic.

So, if you suspect your roof might need replacing, take a flashlight and climb up into your attic. Look around for any water stains, signs of water damage, or beams of light coming through the roof. Any of these indicates a gap or leak that might be a cause for you to start Googling, “Roof replacement near me.”

Look at Your Home Records

The records you have on your home serve as another excellent source of information on whether or not you need a roof replacement. Most people have records on their home’s roof, including details on your roof’s material.

Some materials last longer than others. Composition shingles might last as little as 12-20 years, while metal roofs last 50-75 years.

If your roof has existed for longer than the recommended amount of time, you should consider replacing it.

Check Your Shingles

After intense storms, you should inspect your shingles. Shingles should lie flat against your roof and not be bent upward or missing altogether.

If you find them buckling or cracking, you should consider replacing them as soon as you can.

Shingles also have granules, which, after a lot of wear, can appear in your gutters. Check your gutters for these granules, and if you find them, it might time to replace your roof.

Keep an Eye Out for Moss

Have you noticed anything green growing on your roof?

Green often looks great in your yard, and you might love the look of moss growing on trees or in other areas. Yet, if you find your roof growing some green on its own, it could indicate the existence of trapped moisture. If you discover your roof growing some moss, consider getting it replaced.


Have you noticed a dip in your roof?

Sometimes, when water seeps into your roof, it causes it to sag. So, if you look at your roof and notice that it’s not flat, you should get it redone.
