Fixing Bubbles And Blisters In An Epdm Roof
One problem you might come across is bubbles or blistering in your EPDM roof. This can occur for two main reasons:
Vapour from bonding adhesive
Bonding adhesives are used to attach EPDM membranes to upstands and around the roof perimeter. When these are solvent-based, if they are not allowed to become touch dry before the membrane is applied, bubbles of gas can form, caused by the trapped vapour from the adhesive.
As EPDM is partially breathable, these bubbles are not a huge problem long-term, and will gradually settle down over time. However, in severe cases, it could mean that the membrane has not bonded correctly, and the membrane may need to be peeled back and re-applied.
Expanding or trapped air within the roof structure
If there is water trapped within the roofing structure, or the timber isnt completely dry when the membrane is applied, this can also cause bubbles and blistering to form. This happens when the roof heats up, the water evaporates, and the vapour has nowhere to go.
Bubbles and blisters wont necessarily cause the EPDM membrane to fail, however they can be unsightly. Unless the bubble is over a seam, is in a high-traffic area or you can see that the EPDM membrane on or around the blister is damaged or degraded, it might be better to leave it alone. If one or more of those applies, speak to a roofing contractor.
Does Epdm Have To Be Glued Down
While the rubber roofs are known to be durable, they also need maintained. EPDM roofs are fully adhered or as many call it glued down . The system is not attached mechanically. If you are set on a rubber roof, make sure the roofing contractor is fully trained and experienced in installing a rubber roof.
Cons Of Epdm Roofing:
- Absorbs heat. EPDM is naturally black, so it offers less heat protection than rubber roof materials that are lighter in color. EPDM can be ordered in grey or white for an additional cost.
- Potential weak seams. EPDM seams are sealed with adhesive or tape, which leaves them more prone to leaking than hot air-welded seams.
Thermoplastic polyolefin, or TPO, is a single-ply roofing material that is similar to EPDM but different in several key ways. First, TPO is a relatively new product in the roofing industry, which means its not as time-tested as EPDM and PVC roofing.
However, TPO was created as a more economical and energy-efficient alternative to these other rubber roofing materials, making it a popular choice.

Stick The Bottom Part Of The Underlayment To The Roof Of The House
Install the second course just like the first, using the guidelines on the underlayment to get the correct overlap. When an ice dam forms on a roof , ice and water can work their way up under the shingles and leak back into the house. Also, strong winds can blow rainwater under shingles. Self-stick roofing underlayment can prevent this because it sticks to the roof decking to seal out water. It also seals around nails, which keeps water from leaking through nail holes.
Rolls of self-stick underlayment have a plastic backing so the material won’t stick to itself. The backing is separated down the middle. Line up the lower edge of the roll with the outside of the drip edge. Peel back part of the uppermost backing on the roll, and nail the top corner of the underlayment to the decking. Start pulling the roll across the decking using the backing, making sure the material is lying as flat and as straight as possible as you pull.
You’ll be able to roll out long sections at a time if you have a low-pitched roof, but the underlayment may slip off the eaves on steeper roofs, so roll out no more than 10 ft. there . It’s important to make sure all your underlayment lies flat before you fasten it to the decking. Ripples and lumps can telegraph through the shingles and may be noticeable from the ground.

The Lifespan Of Rubber Roofing
How often you perform checks and maintenance your EPDM roof will play a large role in how long it lasts. It’s also important to find a reputable company with the required experience and skill to complete the job satisfactorily.
In most cases, rubber roofing systems will come with a 15 to 20-year guarantee. However, if it’s properly installed and not exposed to excessive levels of foot traffic, it can last 30+ years.
Tear Off The Old Shingles
Its impossible to properly install new flashing and underlayment if you dont tear off the old roof beforehand. When tearing off the existing shingles, be sure to remove all the old nails or pound them flat. Protruding nails will tear holes in your new shingles. If you have movable items near your house and youre worried they might get damaged, relocate them. Invest in a few large tarps to protect your plants and landscaping and to catch the thousands of nails that will rain down off the roof. It can be downright impossible to remove old self-stick ice-and-water underlayment, but its OK if you have to leave it in place. And if at all possible, have the rented trash bin parked close to the house so you can toss in the old shingles right from the roof.

How Toinstall Rubber Roofing
Although it is said that the rubber roofing installation process is not something easy, it is not bad to learn about it, at least, theoretically. There are some basic steps for the installation.
All of the steps are started by cleaning the roof area like removing the leaves, twigs, and other debris. Aside from the rubber roofing roll, there are some other tools and equipment to be prepared including the drip batten, adhesive tool, nails, hammer, and cutter.

In installing other types of roof layer, a fiberglass sheet is often used to make sure that the layer is attached well and avoid problems like the growth of the moss.
In rubber roofing, the additional layer is not needed anyway. So, you can start it all directly by placing the rubber roll. The only thing to install before the layer is the drip batten on the deck of the roof to strengthen the installation later.
Next, smear the adhesive material on some parts of the roof horizontally. Then, attach the rubber roof gradually. After some parts have been attached well, you can continue by attaching the next parts until the entire rubber roll is attached well. There is a possibility that some bubbles come out due to the glue that is not smeared thoroughly.
After sweeping the rubber roof area, in general, the installation process is done. But for the difficult process, there is a possibility that the installation is not done only in one process.

Epdm Rubber Roof Vs Roofing Felt
EPDM rubber and torch-on felt roofing systems are the most commonly used materials for residential homes in the UK. If you’re still considering your options as to which one to use on your flat roof, here’s a short overview comparing the two materials.
There are pros and cons to both materials. It’s crucial that you take the time weigh up your options thoroughly before making a choice that could affect your home or commercial property.
Epdm Roofing Issues Poor Installation
Proper preparation is key for EPDM installation.
If the roofing area is not properly cleaned, dried and prepared prior to installation, then this too can create problems further down the line.
Our EPDM systems such as HERTALAN® and RESITRIX® can be installed on most substrates, however you should always check first that the substrate you are using meets the installation requirements, and install a protective barrier if needed.
If the surface is damp in any way, there is the possibility that the membrane will not adhere to it. This can cause air and moisture to be trapped underneath, which can create a bubbling effect.
You may see some waviness or unevenness on your roof, this is usually found on older roofs where there is residual moisture, on decking where there is natural moisture and on insulation where you can frequently see movement and shrinkage. Due to EPDMs extreme flexibility, the function of the membrane is not affected, so these changes are merely cosmetic.
