Just wondering how to roof a house might make you feel burdened. You may, however, complete an easy roof installation if you’re prepared to put in the time and money, especially if you want to place a roof on a house that isn’t standard in size or style. You can set up or fix any roof if you have all the essential supplies and tools and pay close attention to detail.

Generally speaking, roofing a house entails more than merely installing external shingles. It also necessitates the cautious and meticulous installation of all other roof parts, such as metal flashing, underlayment, and ridge cap.

It also demands knowledge of the different materials used and how they combine to weatherproof your home.

Materials needed for roofing a house

You’ll need the following basic items to perform a thorough job of installing a new roof:

  • Asphalt or asphalt-composition shingles
  • Roofing nails
  • Flashing for vents and valleys
  • Drip edge
  • Roofing sealant
  • Self-adhesive waterproof underlayment
  • Felt paper

Since we’re considering the installation of a traditional residential roof, the primary material for the outside is asphalt or asphalt composition.

Asphalt (or asphalt-composition) materials are employed in the laying of roughly 80% of all residential roofs, with a lifespan of 20-25 years on average.

The tools you will need

  • The following is a list of the tools needed to replace your roof:
  • Hammer
  • Extension ladder
  • Roof harness (*for safety purposes*)
  • Chalk line
  • Scaffolding and tarpaulin (to protect from falling materials)
  • Work gloves utility knife
  • saw
  • Caulk gun (for adding sealant)
  • Straight edge
  • Tin snips
  • Air compressor or air hose (for removing debris)
  • Roofing stapler/nailer

If your house has a basic, traditional residential roof, adding a new roof will be a lot easier.

Notwithstanding, if your roof has a lot of structures, you’ll require the appropriate tools to cut and shape the flashing for an accurate fit, which is where the tin snips and circular saw come in handy.

How to Roof a House in 11 Easy Steps

1.            Obtain a permit

Check your local home construction codes and get all relevant permits before doing anything. The last thing you want is to begin roofing only to be forced to stop due to a lack of authorization. Different construction codes apply in each municipality, city, or township, and it is your responsibility to comply with them before you begin roofing your home.

2.            Get rid of the old roof.

The first and most apparent step is to clean and strip the old roof in readiness for putting the new one. Even if you’re merely replacing flashing and underlayment, you’ll first need to remove the old roof.

3.            Set up the underlayment

The next step is to cover the naked roof sheathing with a self-adhesive underlayment. Since it will operate as a shield against rain, wind, and snow, this underlayment has to be waterproof. Besides, certain building rules now specify how much underlayment must be used, as well as how much of the roof it ought to cover.

4.            Use tar paper to cover the underlayment.

The next thing to do is add another protective layer over the underlayment. You’ll need felt paper No. 15 or No. 13 (commonly known as “tar paper”), which you can get at most home improvement stores.

This felt is completely waterproof, as it has been treated with an asphalt or asphalt-composition mix. As you progress up the roof, ensure each consecutive layer overlaps by about 2 inches.

5.            Add flashing

The majority of homeowners choose to put drip edges flashing around the eaves of their new roof to make it seem as nice as possible.

To maintain this flashing in place, just nail it down. This drip edge keeps materials from curling above the edge of your roof and provides it with a lovely, finished appearance. After a strong storm or significant snowfall, you can also flash the roof’s valley, as this is where water seems to pool. Flashing is also required for any structures that protrude from the roof, such as chimneys or vents.

6.            Place the starter shingles

According to roofing experts, the “starter shingles” are the initial shingles installed on the roof. It’s critical to get their placement and orientation right because they’ll serve as the foundation for the subsequent rows you’ll be laying.

7.            Install the shingles

This is where you’ll start laying the external layer of your building’s roof. You only need to cut the tabs from the 3-tab forms and adhere them with their self-sealing adhesive coating as you prepare to set down the first row. Besides, ensure that the strips face down along the eaves.

8.            Nail down the layer

Roofs need to be as wind and rain resistant as possible, which means you’ll need to ensure your materials are securely fastened to the surface. This is accomplished by simply nailing them. Each layer of shingles should be nailed directly over the roof and flush with the previous ones.

9.            If necessary, add extra flashing

When it comes to installing a new roof, you can never be too diligent. You have to double-check that each structure or architectural flourish has been taken into account. As a result, dormer flashing is required at this time.

10.          Cap the ridge

The ridge is the roof’s highest point. This ridge is not difficult to spot on a conventional building since it is just the top section where the two sloping sides of the roof meet. The ridge must be capped to provide extra protection to the roof.

11.          Remove any dirt and seal any visible nails.

This final stage is essentially a clean-up step in which you attend to all of the minor details. For example, you may discover that some are still protruding, in which case you have to flatten everything with a hammer and seal up anything that is exposed.


The thought of roofing a house alone is somewhat overwhelming. However, if you follow these procedures to the letter, you will have no issue installing a roof that enhances its capabilities and durability. Notwithstanding, some roofing issues may necessitate the assistance of a professional. So, if you need a roofing installation service that is swift and effective, you may want to consider hiring expert roofing contractors.
