Everything You Need to Know About Installing a New Roof

No matter the size or structure of your home, one major priority that should never be ignored is installing a sturdy roof. Installing a new roof is a complex task that requires careful planning, safety precautions, and attention to detail.

For many people, figuring out how to select the right material and hire a reliable contractor can be overwhelming. That’s why we put together this comprehensive guide – to demystify the process of buying and installing a new roof!

From understanding the different materials available to budgeting and timeline considerations, we’re here to answer all your questions so you can finally make the move from an old roof to a brand-new one worry-free!

Installing a New Roof

1. Selecting a Trusted Contractor

Choosing the right contractor can make all the difference in your roofing project. A reliable, experienced contractor can ensure the job is done correctly, on time, and within budget.

Start by seeking recommendations from friends, neighbors, and local hardware stores, then conduct online research to check reviews and ratings.

Whether you are looking for Tampa Bay roofing solutions or Florida roofing contractors, make sure to ask prospective contractors for credentials and insurance details.

It’s also a good idea to get multiple estimates before making your decision – often, contractors will provide free estimates so you can compare the scope of work and pricing more easily.

They say that the cheapest option may not always be the best, but remember that contractors may have last minute cancelations from clients and may be able to offer a really good price just to fill in the gap that has arisen in their schedule.

2. Budgeting for a New Roof

Having a clear budget from the start and clearly communicating it to your contractors is crucial. If you are designing a new roof, you can always ask your architect or structural engineer to work around this. Their design can vary depending on your needs.

Budgeting is a crucial part of any home renovation project, especially when it comes to installing a new roof.

The cost of a new roof can vary widely based on several factors, including the type of material chosen, the size and pitch of your roof, and the region you live in. The latter will determine the day rate for your contractor.

Again, you can ask your shortlisted contractors to quote separately for work and for material. Asphalt shingles, for instance, are generally more affordable than slate or metal roofing. if you want your quotes to be comparable, all contractors should quote for the same material to be used.

Keep in mind that while higher-end materials may be more expensive upfront, they can offer greater durability and longevity, which can save money in the long run.

3. Roofing Permits and Regulations

Before you embark on the journey of installing a new roof, it's important to understand the legal requirements involved.

In most areas, you'll need a roofing permit from your local building department or municipality. This permit certifies that your project is by local codes and regulations, ensuring the safety and soundness of the roofing structure.

The process to obtain a permit often involves submitting a detailed plan of the project and, in some cases, an inspection during or after the project. It's crucial that your contractor is well-versed in these regulations and is willing to handle the permit application process.

Failure to obtain the necessary permits can result in fines, challenges when selling your home, or even the need to remove and reinstall your roof.

4. Preparing for Installation

Before the actual installation of your new roof begins, there are several preparatory steps that homeowners should undertake to ensure a smooth and successful project.

Speak to your neighbours about the work and let them know how long it will take.

You should clear your home's surroundings of any vehicles, decorations, or other items that could be damaged by falling debris. A safe perimeter is essential not just for your property, but for the workers' safety as well.

As your contractor will erect scaffolding around your home, it's a good idea to ensure your car is parked somewhere safely, away from the works. Ask your neighbours if you could use their allocated space for a period of time.

Prepare the inside of your home. Roofing work can cause vibrations that may dislodge items within your house. Consider removing picture frames, mirrors, or other wall-mounted objects to prevent them from falling.

If your attic is already in use for storage purposes, think about emptying it before the work starts. Covering the items stored in the attic with just protective sheets will not safeguard them from dust or small debris. This may well be your golden opportunity to clean up unwanted items!

5. Installing a New Roof - the steps

If you have appointed your contractor and are ready for the work to begin, you should expect the following steps to take place:

1. Safety Precautions

Your contractor should ensure they have the necessary safety equipment such as harnesses, helmets, non-slip shoes, and fall protection gear. A scaffolding should be erected around to allow for ease of access externally. If you are replacing an existing roof, then the scaffolding should be erected higher and plastic sheets to cover the home from rain should be installed.

2. Materials and Tools

If you are removing an existing roof first, ensure you have skips available to collect old tiles and any timber removed.

Make sure that the material to be used are on site to avoid delays that can cost. This includes roofing materials (shingles, tiles, metal sheets, etc.), underlay, insulation, roofing nails, flashing, vents, and more.

3. Install Underlay material

Lay down a roofing underlayment as a moisture barrier. This helps protect the roof deck from water infiltration. The type of underlayment depends on your roofing material.

4. Install Flashing

Flashing is used to prevent water from penetrating joints and seams in the roof. Install flashing around roof penetrations such as vents, chimneys, and skylights.

5. Install Roofing Material

The method of installing roofing material varies based on the type you're using. Here's a general guideline for a few common roofing materials:

  • Asphalt Shingles: Start at the bottom edge of the roof and work your way up. Nail shingles in place, overlapping each row to shed water properly.

  • Metal Roofing: Attach metal panels using screws and gaskets to create a weather-tight seal. Follow the manufacturer's instructions for proper installation.

  • Tile Roofing: Lay down the tiles in rows, interlocking them to create a secure fit. Nail or fasten tiles to the roof deck according to the manufacturer's guidelines.

6. Ridge Vent Installation

Install ridge vents at the peak of the roof to ensure proper ventilation. This helps prevent moisture buildup in the attic.

7. Ventilation and Insulation

Ensure proper attic ventilation and insulation to prevent heat buildup and moisture issues. Improper ventilation can lead to premature roof deterioration. Your building inspector will also explain what the current requirements are and your contractor is also expected to be familiar with the most recent building regulations, as these change often (especially around insulation requirements).

8. Add Window fixtures

If your design includes windows, these will be added at this point to fully insulate the roof space.

9. Finishing Touches

Install any additional roof elements, such as chimney caps, pipe boots, or gutter systems. Ask your contractor to provide photos of these as you're unlikely to be able to get up on the roof to check connections are made correctly!

10. Clean Up

Once the work is complete, thoroughly clean the work area, removing any debris and nails. Dispose of old roofing materials responsibly.

6. Final Inspection

Inspect the entire roof to ensure all materials are properly installed, and there are no visible issues. If you are unable to do this yourself, your can ask the contractor to provide ample photos for this, to give you peace of mind.

The contractor will also need to supply photos to the building inspector, so the project can be signed off.


Installing a new roof can seem intimidating, but with the right preparation and knowledge, it doesn’t have to be!

It's important to note that this is a simplified overview of the roof installation process. The complexity and specific steps may vary based on factors like the type of roofing material, the slope of the roof, local building codes, and climate considerations.
