How To Stay Safe When Installing Roof Shingles

Safety should always be your top priority when working on a roof. Wear safety gear such as gloves, safety glasses, and non-slip boots. Use a sturdy ladder to access the roof and have a partner to help you with the heavy lifting.

Be aware of your surroundings, especially the edge of the roof, and avoid working on wet or slippery surfaces.

DIY roofing isn’t the best idea for many reasons, and we do not recommend anyone attempting it.

How To Install A Roof On A House

*The installation process will change based on the type of roof, material, and other options you choose. We recommend installing the best type of roof for the Maryland area.

1. Planning And Preparation

Inspecting a roof before new roof installation

Assessing Your Current Roof Condition

Before beginning a new roofing project, assess the condition of your current roof.

Look for signs of damage, leaks, and wear. Take note of all the exposed nails, damaged shingles, and areas where water may be pooling.

You can also inspect your attic for signs of water intrusion or mold. Be sure to document your findings with a few photos to help with the planning process.

Researching Local Building Codes And Permits

Each area has its own set of building codes and permit requirements for roof installations.

Check with your local building department to ensure you are following the proper guidelines for your project. This may include restrictions on the type of roofing materials allowed, the number of layers of shingles permitted, and the roof’s fire rating.

Selecting A Qualified Roofing Contractor

If you choose to hire a professional, research and select a qualified roofing contractor. Look for a contractor with a solid reputation, great reviews, proper licensing, and insurance. This is where you won’t want to let roofing installation costs affect your judgment.

Estimating Costs And Budgeting

Estimate the cost of your roofing project by taking into account the materials, labor, and any necessary permits. Create a budget and be prepared for unexpected expenses that may arise during the project.

Preparing For Roof Replacement

Before starting your roof replacement, clear the area around your home of any debris or obstacles. This will help protect your property and make it easier for workers to access the roof.

Protecting Your Property

Use tarps and plywood to protect your landscaping, windows, and other vulnerable areas of your property during the roofing process. Be prepared to clean up any debris that may fall during the project.

2. Removing Old Roofing Materials

Removing old house roof

Begin by removing all the old shingles and underlayments from your old roof. Use a roofing shovel or pry bar to carefully lift and remove the materials, taking care not to damage the roof deck underneath.

Dispose of old materials responsibly.

3. Inspecting And Repairing The Roof Deck

Inspecting roof deck

Once all the old shingles and underlayment have been removed, inspect your roof deck for damage or rot. Replace any damaged or rotting boards, and make sure the deck is clean and free of any debris.

Ensure that all nails and staples have been removed or hammered down flat. This is also a good time to repair or replace any damaged fascia boards.

4. Installing Proper Ventilation And Insulation

Proper ventilation and insulation are essential for maintaining the health and longevity of your new roof.

Ensure that your attic has adequate insulation and that there are sufficient soffit vents and ridge vents installed. Proper ventilation helps prevent issues like ice dams and mold growth, while insulation helps regulate the temperature inside your home.

5. Installing The New Roof

Laying The Underlayment

Before installing the new roofing materials, lay down an underlayment. This can be felt paper or an ice and water shield, depending on your climate and local building codes.

The underlayment provides an additional layer of protection against moisture and helps create a smooth surface for the roofing materials.

Installing Drip Edges And Flashing

Drip edges and flashing are essential components of a properly installed roof.

Install the drip edge along the roof edge to prevent water from seeping underneath the roofing materials. Install flashing around roof features like chimneys, vents, and valleys to provide extra protection against water intrusion.

Laying Roofing Paper

Roofing paper, or tar paper, is another layer of protection for your roof. It’s typically installed over the underlayment and helps create a barrier against wind-driven rain and other elements.

Start at the bottom edge of the roof and work your way up, using an overlapping pattern to ensure proper coverage.

Installing Roofing Materials

Installing roof shingles

Depending on the type of roofing material you’ve chosen, the installation process will vary. Below are some general guidelines for the most common types of roofing materials.

Asphalt Shingles Installation
A. Start at the bottom edge of the roof

Begin the shingle installation at the bottom edge of the roof. This will help create a solid foundation for the rest of the shingles.

B. Install starter strip shingles

Apply starter shingles along the bottom edge of the roof. These special shingles help create a tight seal and prevent shingles from being lifted by strong winds.

C. Apply shingles in a staggered pattern

Install the asphalt shingles in a staggered pattern, working your way up the roof. This pattern helps create a strong, watertight barrier and gives your roof an attractive appearance.

D. Trim shingles around roof features (vents, chimneys, etc.)

When you reach roof features like vents and chimneys, trim the shingles to fit around them. This may require cutting the shingles with a utility knife or using a straight edge for precise cuts.

Metal Roofing Installation

For metal roofing, begin by installing the proper underlayment and then follow the manufacturer’s instructions for installing the metal panels. Be sure to use appropriate fasteners and sealants for a watertight seal.

Clay And Concrete Tiles Installation

Tile roofs require a specialized installation process, involving the use of battens and clips to secure the tiles. Follow the manufacturer’s instructions and local building codes for proper installation.

Slate Installation

Slate roofs are installed using a similar process to tile roofs but require additional care due to the fragile nature of the slate. Ensure that the roof structure can support the weight of the slate, and use proper fasteners to secure the slate tiles.

Wood Shake Installation

Wood shakes are installed using a staggered pattern similar to asphalt shingles. They require proper ventilation and should be installed over a felt paper underlayment for optimal performance.

6. Replace Or Cut New Vents

If necessary, replace or cut new vents for your roof during the installation process. Proper ventilation is essential for the health and longevity of your roof.

7. Installing Ridge Vents And Ridge Caps

Ridge caps installed on asphalt roof

Once all the roofing materials have been installed, it’s time to add ridge vents and ridge caps. Ridge vents help provide proper ventilation for your attic, while ridge caps create a watertight seal along the peak of your roof.

Install the ridge vents according to the manufacturer’s instructions, and then apply ridge cap shingles or special ridge tiles over the vents to complete the installation.

8. Add Gutters

Attaching aluminum gutter and down spout to house fascia

After the roof installation is complete, don’t forget to add gutters. Gutters help direct water away from your home’s foundation and prevent damage to your landscaping.

Install gutters along the edges of your roof, ensuring they’re properly sloped and connected to downspouts for efficient water drainage.

Inspecting And Maintaining Your New Roof

Regular Roof Inspections

To keep your new roof in optimal condition, schedule regular roof inspections. This will help you identify any potential issues early on, preventing costly repairs or damage to your home.

Cleaning And Maintenance Tips

  • Keep your roof clean and free of debris, such as leaves and branches.
  • Trim any overhanging tree limbs to prevent damage to your shingles.
  • Clean your gutters regularly to ensure proper water drainage and prevent ice dams in colder climates.

Addressing Minor Repairs

If you notice any minor issues with your roof, such as missing or damaged shingles, address them promptly. Taking care of small problems early can prevent them from becoming larger, more expensive issues down the line.

Choosing The Right Roofing Materials

Different roof materials and types

There are a variety of roofing materials available on the market, each with its own set of benefits and drawbacks. Some of the most popular options include:

Asphalt Shingles

Asphalt shingles are a popular choice due to their affordability, ease of installation, and variety of styles and colors. They have a relatively short lifespan compared to other materials, typically lasting 20-30 years.

Metal Roofing

Metal roofing is known for its durability, energy efficiency, and low maintenance requirements. It can last up to 50 years or more, depending on the type of metal and the quality of installation.

Clay And Concrete Tiles

Clay and concrete tiles are known for their beauty and durability. They can last up to 50 years or more but may require additional structural support due to their weight.


Slate is a high-end roofing material known for its beauty, durability, and long lifespan. It can last up to 100 years or more but requires specialized installation and maintenance.

Wood Shake

Wood shakes provide a natural, rustic appearance and can last up to 30 years with proper maintenance. However, they can be susceptible to rot and insects and may require additional fireproofing treatments.

Synthetic Roofing Materials

Synthetic materials, such as rubber or plastic, can mimic the appearance of other roofing materials while offering improved durability and lower maintenance requirements. Their lifespan varies depending on the specific material and installation quality.

Factors To Consider When Choosing Materials

When selecting roofing materials for your home, consider factors such as:

  • Cost
  • Durability
  • Maintenance requirements
  • Aesthetic appeal

Additionally, take into account local building codes and any specific requirements for your climate, such as fire resistance or protection against ice dams.

Recently we hired Integrity Pro to design and complete a combination bathroom and Laundry room in our basement.We knew for quite sometime this would be a big time consuming job. We actually interview at least 6 other construction companies. We found out that a lot of plumbers were not interested in the construction aspects of this type of work. We found out that anyone offering to do this for 7-8 thousand dollars was not trustworthy.More than once we were ready to pull the trigger only to walk back from the ledge for different reasons.The first thing that stood out on the Integrity estimate was that big fat liability policy that was part of the estimate proposal. As a retired Casualty Insurance Professional this was definitely a determining factor. The other was the fixture allowance.But it did take 2-3 conversations to lead to the big hand shake.Then the next “feel good” factor was Alberto the lead carpenter. He came in on a Saturday after the plumber because he needed to get a jump on things. He worked every Saturday until finished.We saw Mike the Project Manager like 4 times. Very reassuring.The door to the laundry room needed some creative thinking. Once again great results.For us this was a once in a life time project, we had much to loose if done incorrectly, but much to gain when done right. That is where we are, on the plus side. Well done.Anthony Bynum

This company is very responsive. Not only did Danny (owner) listen to our concerns, but he heard our concerns. Many days, I was leaving as the workers arrived. Danny would leave post it notes to ensure the contractors addressed any concerns from the day before. The contractors are very respectful of our home. They cleaned up every afternoon so as not to leave our house in disarray.My fireplace turned out beautifully. My bathroom doors were moved and the new locking barn darns turned out beautifully. Danny is having a custom threshold designed to make the transition between too rooms seamless. Danny took a load barring wall down to open up the kitchen and the back room. Danny ensured the openings to these rooms were at least 36 inches. Ensuring the house is ADA accessible was very important to me.

Our project coordinator on site was Alberto. He was so fastidious, and was so committed to making the job look fantastic at the end. He even came back after he realized he forgot to put some thing on our final cabinet installation even thought he was in his truck, on his way out. He was just so excellent and we can’t have asked for a better project result.

I’m so happy to have found Integrity Home Pro! After working with multiple contractors on various house projects, Integrity Home Pro has been a breath of fresh air. They’re professional, courteous, knowledgeable, reliable, show up when they say they’re going to, and are quick to respond to phone calls and emails. Not only that, their work is excellent. We hired them to renovate a bathroom and were so impressed we hired them to renovate our sunroom and kitchen and make various improvements around the outside of our home. I cannot recommend them highly enough and will work with them again for any future home improvements.

My wife and I reached out to Integrity Home Pro for a quote to repair/replace wood under our bay windows that started rotting years ago. Within a few days, we had an estimate with several different options, and reasonable price set for the work done, as well as an estimate for how long the work would take.Within 3 weeks, Integrity Home Pro sent out their team to replace our rotted wood with panels and had finished the work within the time originally estimated. We're so happy with the work they've done, that we will certainly be reaching out again for more work on our home.Long and short: Integrity Home Pro has shown us professional courtesy, impressive workmanship, and genuine care for our needs. The quality of service is a rarity, and we plan on reaching out to Integrity again in the near future.Photos provided to show the before and after

Integrity Home Pro was a pleasure to work with. I had extensive hail damage to my house and the process of getting information to my insurance and approval for a full replacement was a long process. Ben at Integrity was very patient and extremely helpful every step of the way. He assisted with everything the insurance needed so that now I have a new roof and siding. The installers were outstanding and when they were finished you could not see any debris on the lawn or damage to any bushes. I used Integrity about 10 years ago for the previous roof that the hail damaged ( I thought they were terrific then) and I think they only have improved with time. I highly recommend them!

Integrity Home Pro did an excellent job at remodeling our bathroom. They are very skilled, professional, and they work together to get the job done in a timely fashion. They were very patient, attentive, and courteous, and always kept us abreast every step of the way. Our newly remodeled bathroom exceeds our expectations and is simply beautiful. We could not have asked for a more dedicated and devoted team.

Integrity Home Pro were very pleasant and easy to work with when our roof was damaged by a tree branch. They replaced my roof quickly in the morning. Also, I am a returning customer knowing they did a great job replacing my roof 20 years ago.

Integrity Home-Pro just completed remolding our kitchen. The process took two weeks. Elmer Lopez did the work. He worked non-stop everyday; his workmanship is premium. Tera Ingwersen guided us through the process from the office on a regular basis and was always available to answer questions. Integrity's quote for the work was significantly less than a quote given by another company. Integrity's owner, Danny Peterson, personally came when we called about getting a quote. He followed up on two occasions as the work was being done. Integrity Home Pro has done other major projects on our home and we have been pleased each time.
