Residential Roofers in Rochester


On a house, the roof performs triple duty. It maintains the structural integrity of the building and provides insulation. But it should also enhance a home’s appearance. At JJ Construction, we take special care with residential roofers in Rochester so both style and functionality stand the test of time.

Only first-class roofing materials from trusted companies are good enough for us. , GAF Materials Corporation, CertainTeed, and Owens Corning are some of our favorites. We know we do great work, and we want it to last a long, long time. The quality of materials matter. You’ll experience the difference… because you won’t have premature or unexpected problems.

Contact JJ Construction at (585) 865-5428 to talk to our roofing contractors about your roof. Let us take a look and assess your needs. Then we can make suggestions so your roof is both sturdy andattractive. Maybe you’ll need a whole new roof, but maybe with a few repairs you’ll be in fine shape.

We know a roof is a significant investment. But a roof that’s in disrepair can cost you money in heating and cooling costs. And if a leaky roof lets water in, mold or bacteria could develop. This can lead to both structural and health concerns. Roofs should last for decades, so spending money now can save you a lot in the long run.

Commercial Roofers in Rochester

At JJ Construction, we’re not just residential roofing contractors in Rochester, NY. We’re equally committed to commercial roofing projects in Rochester. In our
area, roofs can take a real beating from the weather. Many offices and businesses trust their roof repair or replacement to us. We have a reputation for doing outstanding work with superior materials. Once we’ve finished a job, your roof stays in great shape for a long, long time.

Commercial buildings come in many sizes and shapes. But that’s OK; we have experience with all sorts of roofs. Flat roof? Steep slope? Whether you need a new roof or a repair, JJ Construction can handle the job.

We’re a business, too, so we know how important it is for you and your employees to focus on work. That’s why we strive to make our roofing process, from the initial quote to the finishing touches, as straightforward and fast as possible. We believe in two-way communication. We listen to your needs, explain how we can help, and then keep you informed during the process. No secrets or surprises.

Roof Repair in Rochester

Not all roof problems require entirely new roofs. For some Rochester home, a first-rate repair job will keep the roof going strong for many more years. Maybe a number of shingles should be replaced. Perhaps the flashing needs updating. Sometimes ice dams take their toll. (Ah, that Rochester weather again!)

Repairs are possible when certain roofing issues are caught early enough. If left too long, they worsen, and the whole roof is affected. Of course, that takes more time and money to fix.

Let JJ Construction’s roofers check out your residential or commercial roof. We may be able to catch problems while they’re still small enough to patch. We want your roof in tip-top condition, but we won’t do more work than is absolutely necessary. We have a reputation for honesty, and we plan to keep it that way.

Emergency Roof Repair in Rochester

Most roof problems happen over time, but every once and a while… BAM! A roof goes from decent to damaged in the blink of an eye. What can cause a roof crisis? Unfortunately, lots of things, including:

  • A hole made when a new device, such as an antenna or skylight, is (poorly) installed
  • A really, really bad storm (Remember, this is Rochester.)
  • An old tree that refuses to stand up anymore
  • A lightning strike
  • Fire
  • An ice dam

When a roof problem is urgent, you need it fixed fast and you need to contract a roofer in Rochester, NY. JJ Construction has 24-hour emergency service for Rochester roof repair. We’ll be on the spot ASAP to give you a free quote. Once we’re on the job, we’ll have your roof in proper condition again soon.

Step-by-Step Roofing Process Explained by JJ Construction

Our Roofing Process for Rochester NY


  1. Inspection and Preparation
  2. Dismantling the Old Roof
  3. Applying the New Underlayment
  4. Installation of New Shingles
  5. Wall Flashing and Ventilation Replacement
  6. Rooftop Cleanup
  7. Quality Inspection

At JJ Construction, we specialize in the installation, renovation and replacement of residential rooftops for our customers. As experts in Rochester roof installation, we offer complete solutions for installing metal rooftops, wooden shingle rooftops, slate rooftops and more. While the construction of a rooftop depends on the support structure beneath and whether the roof is pitched or even, we’d like to share the step-by-step process that we use for the vast majority of our roof jobs.

1: Inspection and Preparation

Before roofing materials make their way to your home, one of our dedicated and knowledgeable team leaders needs to inspect your home and come up with an organized plan for removing your old, worn rooftop. A good inspection removes a great degree of uncertainty with the rest of the roofing process, and can either speed up the entire job when done well or slow it down greatly when done poorly.

Our inspectors use tried-and-true methods to determine the best spots to place ladders, the appropriate places to start disassembling the old roof and the best way to begin installing the new one. Once this plan is ready to be put in action, the rest of the team comes with all of the materials necessary; protective tarps get placed over your home and yard to protect your property from falling debris.

2: Dismantling the Old Roof

Once we have a plan, our Rochester roofing specialists quickly set to work dismantling the former rooftop installation on your home. While removing shingles and other materials, we verify the integrity of your roof’s substrate in order to make sure that it can support the new roof. If we determine that the substrate surface has deteriorated over time, we’ll put a repair plan into action immediately.

When dismantling rooftops, we typically work in specific phases so that no large section of the roof is left unprotected for any significant period of time.

3: Applying the New Underlayment

Your new rooftop shingles need to have a reliable, sturdy underlayment to rest on. After dismantling your old roof installation, we verify your existing underlayment to determine whether we need to repair it or replace it. If your underlayment is in good shape, we may be able to simply install the new roof over it, but this depends on how severely weather and other conditions may have affected it over time.

4: Installation of New Shingles

The majority of our Rochester roofing jobs involve installing new shingles either out of wood, slate or a variety of other materials. Once the new underlayment is in place, we can begin attaching the new shingles. We use high quality fasteners to ensure that our roof shingles stay in place longer and resist inclement weather better than our competition.

When installing new singles, we use professional scaffolding instead of simple walkboards that can penetrate the roofing membrane and cause accidental damage. This ensures the fastest and most professional results.

5: Wall Flashings and Ventilation Replacement

In order to guarantee the best possible results, we need to replace wall flashings and ventilation ports on the homes we work on. This ensures that your new roof is perfectly compatible with the structure of your home and offers the unified aesthetic appeal that you want in your newly renovated home. This service improves the performance of your home’s ventilation and the insulating capabilities of your roof.

If your rooftop has a ridge vent, it is at this time that we install it, after the shingles and flashing are already in place. Common among pitched roofs, the ridge vent sits on the very top portion of the roof, at the corner where the two sides of the pitch meet.

6: Rooftop & Ground Cleanup

Once the new roof is properly installed, we use rakes, blowers and magnets to remove any debris that may be left on or around the worksite. This step ensures that your rooftop is left in pristine condition and that you don’t have to worry about finding debris in and around your yard. Following cleanup of the actual roof, we pack and remove the tarps covering your property and remove the trash container.

7: Quality Inspection

At this point, your home is ready for a quality inspection from our field supervisor. This inspection covers not only the integrity of the new roof and its ability to withstand the elements for years to come, but also the completeness of the cleanup operation and every other aspect of the job. We use this final inspection to ensure that your needs have been met to the letter.

A Roofing Job Well Done

As one of the most reputable roofing companies in Rochester, NY, we ensure complete satisfaction with all of our roof installation and upgrade services. Our laborers are highly trained and dedicated to doing a good job. Furthermore, we make sure each one is properly licensed, insured and bonded for the task at hand. Our commitment to safe, high quality roof installation is what makes us a leader in our field. Give us a call and ask for an estimate on your home improvement project.

Roofing Materials We Proudly Use

Sometimes it’s better to start from scratch. If your roof is very old or heavily damaged, a full replacement might be in order. This involves tearing off all the old materials and laying a brand new roof. Once it’s on, you’ve increased your home’s value… a LOT. There won’t be any leaks, so you and your possessions will stay dry as a bone.

You want your new Rochester roof to last. With JJ Construction, it will. We do high quality work, and we choose high quality materials. Some of our favorite products are from:

  • GAF Materials Corporation: This company is a staple in the roofing industry, with almost $3 billion in annual sales.
  • CertainTeed: This corporation began over a century ago as a general roofing manufacturing company. Now they produce a wide variety of shingles, low-slope roofing systems, metal roofing, and solar roofing supplies. What don’t they make???
  • Owens Corning: It’s been a Fortune 500 company for over 60 years in a row. They got there with top-of-the-line products.

How can you tell if you need a new roof? Warning signs include:

  • Curling, cracked, or disintegrating shingles
  • Bald spots
  • Moisture in the insulation
  • Advanced roof age
  • Water leaks or damage

Play it safe, and find out for sure. Call JJ Construction, and we’ll give your roof a thorough inspection. We do it all: residential and commercial roofs.

Roof Vents

Roof vents are lesser-known but extremely important parts of roofs. They serve two purposes.

  • An intake vent lets outside air into an attic or ventilation space. It’s typically on a low point of the roof.
  • An exhaust vent lets air from an attic or ventilation space escape to the outside. It’s usually near the roof peak.

The most common intake roof vents used in Rochester are the long, continuous soffit vent or shorter individual soffit vent. Exhaust vents have more variety, including:

  • Ridge vent: Located along a roof ridge, it’s sometimes covered with shingles.
  • Static vent: Individual vents are put in near the roof ridge.
  • Gable-end vent: This variation is installed in a wall near — you guessed it! —  a gable’s peak.
  • Turbine vent: The wind rotates the vent’s blades to draw air out.

Improper venting leads to problems. Your house or building overheats, and cooling costs skyrocket. Roofing and insulation materials break down. Moisture builds up, causing damage and mold growth. And because of our famous  (or infamous) Rochester winters, poor ventilation allows ice dams to form.

At JJ Construction, our Rochester roofing contractors can help you avoid vent issues. We install roofs, replace, maintain and repair roof vents. Though a properly installed vent should last a long time, high winds or intense hail sometimes cause damage. By fixing or preventing problems, our work saves you money in the long run.

Roof Shingles

A great roofing contractor in Rochester has two jobs: excellent technique and first-rate materials. We’re at the top of our field, so we’re not about to skimp on supplies. We use only the highest quality shingles, so you know that your roof will last for years and years. This isn’t a job you want to repeat anytime soon!

We inspect your roof, assess the condition, and give you a free quote. Then we use the right shingles for the job. Here’s a sample of the materials we use:

  • GAF Timberline Lifetime Architectural Roofing Shingles: They come in a variety of colors and offer a wood-shake appearance.
  • GAF Lifetime Designer Shingles: These provide a multi-dimensional look that mimics slate or wood shake shingles.
  • CertainTeed Patriot Shingles: Colors blend with shadow lines for a long-lasting and attractive roof.
  • CertainTeed Landmark Shingles: Their luxury and designer lines look great and can offer excellent solar reflection.
  • Owens Corning Duration Shingles: These wind- and algae-resistant shingles are available in a variety of colors and contrasts.
  • Owens Corning Oakridge Shingles: Affordable laminated shingles come in many traditional roof colors.

So you see, you have choices. Lots of choices. Our experienced staff can help you select the shingles that fit your style, budget, and needs.

Roofing Terms

Before you hire a roofing contractor to work on your home or business, you should at least have the roofing know-how to know-what you’re talking about (or at least sound like it). Don’t go into your next home improvement or repair project blind. First, familiarize yourself with this beginner’s glossary of basic roofing terminology.

Accumulated Snow: A particular problem during the Rochester deep freeze, heavy snow build up can cause cracks in your roof, which in turn leads to leaks and costly water damage.

Algae: Rooftop fungus that can leave ugly stains on roofs.

Angie’s List: An online directory where consumers can research reviews and testimonials on contractors in their area. Because Angie’s List does not allow anonymous reviews, it is generally considered far more reliable than sites like Yelp.

Asphalt Shingle: The most common roofing material in North America because of their relatively low installation cost. Asphalt shingles come in various types to help them survive water, fire damage, and inclement weather, like snow, wind, and hail.

ASTM: The American Society for Testing and Materials, which sets standards for roofing materials.

Bitumen, Bituminous: Basically another word for asphalt, bitumen is an organic tar-like substance used in many construction materials.

Cupping: When shingles on an existing roof curl or “cup” due to improper installation, over exposure, or a manufacturing defect.

Drip Edge: A strip of metal material placed along the edges of a roof to stop water from dripping onto the eaves, siding, deck (or people!) below.

Dormer: A small structure with windows that sticks out from the slant of the roof.

Eaves: the edges of a roof that meet or overhang the walls of a home or building. Generally, the three feet of a roof closest to the edge.

Flashing: Waterproof material placed around projections like chimneys, pipes, or vents. An area where the flashing is covered by shingles is called a “closed valley.”

Gable Roof: A traditional building design, where two peaked roof planes meet to form a single line.

Granules: The crushed rock and ceramic coating that is used on the surface of most roofing shingles.

Hand Sealing: For steep roofs, or homes in cold weather areas (like Rochester), it may be necessary for contractors to seal shingles by hand.

Hip Roof: A roof with four separate roof planes that come together to form a pyramid. If a child drew a roof on a house, this is what it would look like.

Ice Dams: The bane of Rochester roofs for centuries, ice dams form when melting snow re-freezes near the roof overhang. Ice dams cause snow melt to form a reservoir and can cause leaks and water damage.

Interlocking Shingles: Shingles that fit together to provide wind resistance.

Laminated Shingles: Also known as “Architectural” or “Dimensional Shingles.” Shingles made from two pieces laminated together.

Mansard Roof: A four-sided roof joined by a flat plane surface on top. Mansard roofs often feature Dormers as well.

Membrane: Waterproofing material usually installed on flat roof surfaces to prevent leaks and water build up.

Roofing Contractor: Sometimes called a “roof mechanics,” a roofing contractor is a company or construction worker that specializes in roof installation, repair, or waterproofing.

Subcontractor:A worker hired by a general contractor to perform tasks as part of a larger project. Always ask your contractor if they plan to subcontract any work on your home or building.

Self-Sealant: Sealant that is activated by the sun and heat after installation.

Soffit Ventilation: Ventilation area installed under the eaves.

Valley: The area where two roof planes intersect and form a “V” shape.

Witch Window: also known as “lazy windows,” these oddities are peculiar to American architecture and are most popular in the Northeast, particularly in or near Vermont. These windows are tilted diagonally 45 degrees, so they’re parallel to the roof slope. Witch windows allow a builder to fit a full window into a narrow space between two roof lines. According to urban legend, they’re called Witch windows because it would be difficult for a witch to fly through the tilted design.
