Worse, when you’re not sure of the roof underlayment repair cost, it’s hard to know where to start.

The cost of roofing underlayment is not always discussed.

But, underlayment is as vital to the protection your roof gives as any other element.

So, how do you figure out what an underlayment repair will cost along with the rest of your roof?

Well, it needs to begin with a breakdown of what roof underlayment repair entails.

Roof problems are better solved with a good knowledge base first.

So, keep reading and find out what your roof repair costs will be with a guide to better understand roofing.

Understanding Underlayment

Before choosing to go ahead with roof underlayment repair, it helps to know its main function.

No matter what your roofing problems are, each layer has a defined purpose.

Underlayment is the last line of defense to protect your roof from the effects of climate.

There is a range of choices for roof repair depending on regional conditions.

In Arizona, these elements range from extreme heat and wind to water ponding on a flat roof.

In addition, every roof needs protection from damage caused by nature.

Roof repair costs will generally depend on the type of damage that has occurred.

For example, the high temperatures of summer can loosen or crack roof materials.

Therefore, an exposed underlay that is vulnerable to these conditions needs to be heat resistant.

In contrast, the pooling of water on a roof over time will create leakage through shingles.

Underlayment materials also come with varying degrees of water resistance.

Knowing the effect of these elements will determine the best roof underlayment repair for your needs.

Also, more issues like tree debris or the shape and style of your roof affect the cost of roofing underlayment. 

Choosing Materials

The style of your roof is an important consideration when choosing underlayment material.

Outer roof materials, or shingles, come in different styles and materials.

Then, there is the material of the underlayment that will be affixed to the roof deck.

More issues like tree debris or the shape and style of a roof also affect roof repair costs.

Roof shingles range in material from metal or clay to standard asphalt roof shingles.

Each roofing material has an underlayment best suited to the tile.

Roofing felt is a lower cost to install roofing underlayment.

The asphalt-based membrane is easy to repair with basic roofing materials.

In addition, it provides excellent coverage against seepage.

But, the lifespan of felt is shorter than newer technology.

Though easier to repair, it can at times be less pleasing to the eye.

Synthetic roof underlayment has definite advantages over felt.

Much stronger in design, synthetic is a more flexible plastic covered with asphalt.

As a result, it is more resistant to damage and mold, but synthetic is more expensive to install or repair.

Be mindful that some synthetic underlayment materials do not meet building requirements.

A qualified roofing repair company will know your roof specification needs.

Weights and Measures

The footprint and slope of your roof will also matter to the cost of roofing underlayment.

As well, the original material and condition of the current roof will factor in pricing.

The cost of roof underlayment repair is not only for the visible issue in the roof.

For a repair to last, it must work with the undamaged area surrounding it to stay intact.

The underlayment membrane protects your roof best when it is seamless.

Felt underlayment on the existing roof may be easier to repair.

Yet, the fast adhesives used on synthetic roofs may mean that the entire roof needs replacing.

Other considerations are the age of the roof and the condition of the roof deck.

Holes in roof decking are repairable, but again, the structure must be seamless.

Don’t forget; climate plays a big part in choosing the right kind of underlayment.

For example, Arizona’s heat, wind, and monsoon rains must have the best material for the elements.

All these elements together determine the cost of roof underlayment repair.

So, What Does Roof Underlayment Repair Cost?

In general terms, the fixed costs of roof underlayment repair are easy to address.

For felt underlayment repair, the range is from $0.50 to $0.70 per square foot.

That price includes material and labor.

The cost for synthetic underlayment is about $0.75 to $0.90 per square foot with materials and labor.

Extra costs are always determined on a case-by-case basis.

You should expect to get prices for any repairs to the roof deck and the shingle layer as well.

Take a closer look at where the issues are with your roof.

You may decide that replacement is a more cost-effective way to go.

However, when you go to the expense of work on a roof, you’ll want to last as long as possible.

Of course, all these elements have to fit within your budget.

So, it comes down to choosing the best value that will endure longer.
