Materials Needed For Roof Replacement

Nine Essential Materials Needed For Roof Replacement

Roof Flashing

Roof flashing is a thin piece of metal that is placed at the points where the shingles of your roof make contact with the walls, chimneys, or open valleys. Your roof needs a flashing so that the water can move towards the edge and then off the roof to the drains below. Flashing helps in combating water that gathers over your roof. 

Without it, the water will seep through the shingles and cause damage to the wood underneath. If the quality of your flashing is good, then there is no need to go with roof replacement when you are getting a new roof. So, what are the scenarios in which the roof flashing will have to be replaced?

  • If your flashing rusted.
  • If your flashing deteriorates beyond repair
  • If you are completely remodeling the roof. This includes changing your roof styling then you will have to change the flashing as well.

Roof Decking

The foundation of your roofing system is called roof decking or sheathing. These wooden boards make up the foundation of your roofing system and help support the weight of your shingles. The shingles and all other roofing components will be placed over the roof decking.

So, when you go with a roof replacement, whether the roof decking needs to be replaced or not will be determined by the roofing contractor you hire. But your contractor can know this only by ripping out the old roof that is going to be replaced. If they feel that the integrity of the decking is sound and it can definitely hold up to the new roof that you are going to put up, then the decking need not be replaced. 

Before deciding whether the decking has to be replaced or not, your contractor has to inspect the deck. They will then advise you as to whether your roof deck has to be replaced or not.

Venting System

Every home requires a good venting system in place to maintain an optimal atmosphere during both hot and cold weather. Extremes of climate are not good for your roof. A properly installed vent will not allow the hot air to be trapped inside for too long, nor will it allow the cold air to be trapped inside. Both these will cut short the lifespan of your roof.

A venting system will help to keep the air in your roof to be in constant circulation so that your attic can breathe properly, the atmosphere in your home will be nice and comfortable, and the lifespan of your roof will definitely go up.

So, when you are going with a new roofing system, the roof vents are definitely part of the equation. When you are going for a roof replacement project, you may either use the same type of vent as was used priorly or you may go with a different one altogether. These are some of the roof venting options available in the market:

  • Soffit vents
  • Gable vents
  • Drip-edge vents
  • Fascia vent
  • Cupola vents
  • Ridge vents
  • Off Ridge vents
  • Hip vents
  • Wind Turbines
  • Box vents
  • Power Attic vents

Different vents serve different ventilation purposes; you can select one based on your specific roofing requirements.


The felt or tar paper material atop the decking that will act as additional support and lend protection is the underlayment. When moisture gathers over your roof or your roof is subjected to harsh external elements like snow or thunderstorm, then all it has to do is go through the underlayment to get to the deck. 

It is why having an underlayment is one of the critical components of your roofing system. And your roofing contractor must install a top-notch underlayment so that the integrity of your roofing system is maintained.

Drip Edge

The drip edge is the metal flashing installed at the roof edge to inhibit the water from flowing towards the fascia and other roofing components and into the gutters. Apart from protecting your fascia boards, the location of the roof’s drip edge is such that the water will flow away freely without causing any damage whatsoever to the fascia boards. 

Metal drip edges will give a lovely curb appeal to your look by adding a finished look to your roof edges. Even before you install the underlayment, you must secure the fascia on the eaves.

Something that protects your fascia boards and prevents damage to them should be replaced when you get a new asphalt roof. Let’s say you’re looking to sell your home; the house inspector will check out all aspects, including whether you have a proper drip edge in place. Moreover, a no-drip edge means you are paving the way for rotten fascia or even curled shingles at the roof edge.

Ice And Water Shield

If your property is located in an area that receives plenty of rain or snow, the ice and water shield will go a long way in protecting your roof. Ice and water shield are nothing but waterproof membranes to safeguard your roof from the damage caused due to ice or water. They will also ensure that the rainwater or melted ice water will flow down the roof as opposed to permeating the roof material and damaging the roof.

It is vital to have an ice and water shield if your building and locality are exposed to continuous rainfall.

Asphalt Shingles

It goes without saying that shingles are a necessary aspect of your roof replacement because they are visible to people when they look from the outside. Asphalt shingles, of course, are the most common type of shingles available, and they are some of the best materials too. These must be installed perfectly, or you are putting the safety of your home in danger from external forces.

One of the significant advantages of asphalt shingles (apart from protection from various environmental conditions) is that they are easy to install and look after. Also, there is no dearth of options when it comes to asphalt shingles.

You can choose between 3 varieties of shingles:

Dimensional shingles, 3-tab shingles, and luxury shingles. They also come in a variety of color options. These shingles will last anywhere from a decade to 3 decades, depending on the climate you live in and the quality of the shingle.

Pipe Boots

A pipe boot is a rubber boot made of synthetic material. It goes around all the penetrations and projections of your roof and prevents leaks from happening. Basically, the job of your boot pipe is to prevent the water from getting into your home.

Since water leakage is one of the main concerns with any roof replacement work and boot pipes play a role in preventing exactly that, you must replace the boot pipe when you are going to get a new asphalt roof.

Flat Roof Materials: BUR, Modified Bitumen, And EPDM Rubber

There are some pretty great options for roofing material if yours belongs to the flat roof type.

These include: 

  • BUR (Build-Up Roof)
  • Modified Bitumen Roof
  • Rubber membrane roof like EPDM (Ethylene Propylene Diene Monomer)

These roofing types wear better than the older, more commonly used roofing materials. But there’s a catch, they will cost you more as well! These roofing materials should last anywhere from 10 to 20 years. But if you have opted for a highly reputable builder and maintain it impeccably, you can even make them last up to 25 years on an average so to speak.


DIY roof replacement is no easy task and is certainly not for everybody. We highly recommend that you hire the help of a roofing contractor to do it for you.

Moreover, roof replacement needs specific skill sets and a select list of materials and tools, therefore even if you make a slight mistake it could lead to a huge problem (regarding your roof and in your pocket as well!).

When a roofing contractor comes up with a list of materials that will be needed for roof replacement, knowing what’s needed and what’s not can help you make an informed decision! We hope this guide will come in handy so you know what materials are needed when you are going for a roof replacement for your home. Good luck!
