How Can You Felt A Roof From The Inside?

Felt A Roof From The Inside

Felting a roof is not an arduous task, whether you want to fix it from the inside or outside. And if you are trying to repair a felt roof from the inside, this is for you.

However, you may need the presence of an expert later. Felting a shelter from the inside requires some skillful ideas.

Let’s check out the steps to repairing a felt roof.

How To Felt A Roof From The Inside?

#1. Locate The Leakage Spot

The first thing is finding the leaking spot from inside. It may require you to enter inside the ceiling and examine it.

However, this may be tricky because sometimes, the water might have traveled from the leaking spot to under the deck.

 So to avoid this, try to get inside the ceiling when the rain is showering. When you find the site, you may mark it with chalk.

This technique will make it easy to locate the spot.

#2. Seal The Spot

After locating the leaking spot, ensure you allow the water to drain entirely. You can mark the spot with chalk for recognition in case of a future replacement.

Use a utility knife to cut roofing tar and place it on the shingles. You should focus on the leaked patch and ensure it sticks around it.

You may consider using a scraper to support the leaking spot by caulking around it for an evenly spread.

#3. Examine From Outside

After sealing the leaking spot, note and feel that spot from the outside; you may need more tar to fill the patch. Covering the patched leak spot with caulking will serve as protection for it.

You need to check if there are slack nails. Also, ensure the underlayment and the shingles are in average condition.

You may also need to clear the roof for any dirt accumulated.

Can You Felt Under Roofing Tiles?

You can feel it under roof tiles. The reason is to serve as a layer for installing tiles.

This step is also compulsory for those in the Uk and Scotland under the building regulations body.

Installing roof felt tiles shields the roof space from getting exposed to wind, snow, and the sinking of rain if the roof felt tiles leak or are damaged.

Felting under roof tiles, which is also an underlayment, is to supply an extra layer of insulation to prevent heat from coming out of the building.

What Are The Types Of Roofing Felt?

The roofing felt types are three in number. They are torch-on, self-adhesive roofing felt, and shed felt.

What will determine the suitable one for you are the size of your project and the person roofing it. 

#1. Torch-On Felt

This type of roofing felt should only be installed by roofing experts because it poses a danger when applying hot flames. Torch-on felt consists of three layers that are connected.

However, if the size of your project is small, you may need to use two of the layers. The layers are a vapor control layer, reinforced felt, and a cap sheet with a minimal finish.

 A blowtorch joins these layers are bound to the roof by a blowtorch to create an effective water-shield seal. The lifespan of torch-on felt is within the range of 15-25 years.

#2. Self-Adhesive Roofing Felt

Even from the name, it’s evident that this roofing felt type could be a DIY task. If you are thinking of installing your felt roof yourself, this type is the best for you to apply.

With this type of roofing felt, you can avoid the use of naked flame. Once the bottom peels off, the roof will bond to the substrate.

If you are working on structures like garages, sheds, or tiny houses’ flat roofs, self-adhesive roofing is good. It’s expensive, though it lasts longer.

#3. Shed Felt

Shed Felt is a type of roofing felt that is for sheds. We use shed felt to protect the possession we keep in our garden. This felt style is affordable, easy to install, and not heavy.

However, you will need to paint it often, to keep it new all the time. Shed felt is available in self-adhesive and torch-on felt.

How Can I Attach A Felt Roof?

You can attach a roof felt yourself. However, it requires patience for a smooth and evenly felt roof.

Also, you will need to follow some steps:

#1. Cut Your Felt Into Pieces

The first thing is to calculate the roof area by multiplying the length by the width. For example, if the height is 110 inches (9ft) and the width is 220(18ft) inches, the area square is 24200 square inches(162ft). 

You will continue with this calculation by combining the area of each surface. Also, ensure you add extra inches to get extra felt for the hangover of the underside of the roof.

Finally, cut the roof felt into size with a utility knife.

#2. Tear Off The Existing Roof

Scrape the grits into a pile and remove them. You may use a spade to scrape the rest of the grits.

Ensure you stand in a firm place to attack one spot repeatedly.

Strip the felt slowly from the roof deck. Then use the end of a claw hammer to pull out nails pinning down the felt to the roof.

Ensure the roof deck is free from bulgy and difficult nails–replace them with new ones.

You may need to sandpaper difficult dirt from the surface. Ensure the surface is not wet.

It’s not advisable to apply a felt on a damp surface. It may lead the decking to warp to rot.

Remove the base sheet with a scraper and replace it with a new one. Do the priming to strengthen the felt attachment. 

 #3. Attach the Felt To The Roof

When attaching the roof felt, roll out the felt of the first layer and attach it to the roof’s edge. Ensure the felt is flat while at it.

Also, the flat felt needs to hang over the edge. In addition, make sure the lower edge of the roof is over the downside.

Be careful when rolling out and avoid bubbling. You can use a tack gun to tack the first layer.

Afterward, pull out the felt from the untack end. When pulling the layer, watch out to avoid ripping.

Roll the second layer like the first one. Ensure it is on the opposite of the first layer.

If you lay the first one from west to east, the second should be from east to west.

Roll the third layer and ensure it overlaps the ridge of the roof. Use galvanized clout to nail the felt.

Consider roofing mastic to cover the nail head for permanent roofing. You may consider caulking for the mastic if the roofing is short-term.

Some of the materials needed for felting a roof are- a utility knife, ladder, tape measure, trowel, nails, plywood planks, and roof felt adhesive such as bitumen. 


You can repair a felt roof from the inside. However, it’s just for the meantime.
