Our Founder’s Thoughts on Residential Roofing

Most houses have shingle roofs. I think shingles are the basic type of roofing in a way although they are not inferior to other types. I have shingles on my home. Many people or companies are installing shingle roofs right now. There are many companies out there for you to choose from, because roofers usually start in the industry first by installing shingles. You can get the job done but…

The trick is to do it right and the manufacturer of each product dictates that. We at Andrews Roofing install shingles and accessories the way the manufacturer says to because they designed them. A shingle will be exposed to weather for a long time, but if you want the whole roof system to perform well, last a long time, and look nice you have to install it correctly and use the correct parts, etc. We have been installing residential and commercial shingle roofs since 1997. We are certified to install the products we sell & use.

The only way we can ensure that we put forth our best effort to accomplish this is to have a superintendent present on every job. The superintendent makes sure the installers are doing it right. And yes, we make mistakes but when that happens we will fix it on the spot or return and take care of it.

This short piece of information is what I want all prospective customers to know and to know that behind this “effort” there is a support staff of administrators, managers & estimators, that take their jobs very seriously!

One more note:
Andrews Roofing has a Class A ROOFING License because ROOFING is what we specialize in. Search online to see. We also have Workers Comp Insurance and well above the necessary general liability insurance to do shingle work and gutters because we install larger commercial roofs as well.

Thank you for the opportunity to serve you!

Please contact us if you have any questions or concerns.

Why and How You Should Keep Your Roof Clean

When it comes to keeping a sparkling clean home, you probably focus on keeping the floors mopped, the surfaces dusted and countertops disinfected. But there’s one giant area of your home that probably isn’t getting enough cleaning attention: your roof. As a crucial part of your home’s structure and one of its primary protectors from the elements, it’s really important to keep your roof well maintained so that it can perform to your expectations.

Over time, your roof can accumulate dirt, debris, moss, and algae, which not only affect its appearance but also its longevity. Think about your carpet – if you never vacuumed it, never cleaned spots off of it or gave it a shampoo every once in a while, it would deteriorate and be unusable (not to mention unsightly) long before its lifespan should be over. The same is true of your roof.

Here are just a few important reasons why you should keep your roof clean and tidy:

Reduces Repairs and Prolongs Roof Lifespan: A clean roof is a healthier roof. The accumulation of debris, moss, and algae can damage your shingles by lifting them up or causing them to deteriorate, leading to leaks and water damage. Regular cleaning can extend the lifespan of your roof, potentially saving you thousands in replacement costs.
Enhances Curb Appeal: A clean roof significantly improves your home’s curb appeal. Whether you plan to sell your house or simply want to enjoy a well-maintained home, a clean roof can make a big difference. We’ve all seen the one roof in the neighborhood that’s stained, missing a few shingles or with trees growing out of the gutters. Don’t be that house!
Increases Energy Efficiency: Algae and moss on your roof can trap moisture, making it harder for your home to regulate temperature. A clean roof can improve energy efficiency, reducing your heating and cooling costs.
Protects Your Whole Home’s Health: Algae and moss growth can create an environment for harmful organisms like mold and mildew. These can infiltrate your home, potentially affecting your indoor air quality and health.

So, by now you’re convinced that your roof could use a good cleaning, but what’s the best way to go about that? It can be dangerous to try and get up on the roof yourself for this chore, so here are some safe suggestions.

Professional Roof Cleaning: Hiring a professional roof cleaning service is often the most efficient and safest way to clean your roof. These experts have the knowledge, equipment, and experience to remove dirt, debris, algae, and moss without damaging your roofing materials. Before hiring a professional, make sure they come with a stellar reputation, and are licensed and insured.
Ask About Soft Washing: Soft washing is a popular method that uses low-pressure water combined with specialized cleaning solutions to remove stains and growth from your roof. This method is gentle on your roof while effectively eliminating algae and moss. There are professional companies who specialize in this service, which is less intense than pressure washing, therefore safer for roofing materials.
Schedule Regular Maintenance: Preventive maintenance is key to a clean and healthy roof. Consider scheduling annual or biannual inspections to identify and address any issues before they become major problems. Regular maintenance can also include gutter cleaning, which helps prevent debris buildup.
Use Preventative Measures: To prevent algae and moss growth in the first place, talk to your roofing contractor about having zinc or copper strips installed along the ridge of your roof. Rainwater running over these metals inhibits the growth of these organisms.

Maintaining a clean roof is crucial for the longevity, appearance, and health of your home, so make it a regular part of your annual cleaning and maintenance routine. By doing so, you’ll not only protect your investment but also ensure a safe and comfortable living environment for you and your family.

If you have concerns about the cleanliness or condition of your roof, contact Andrews Roofing today. We’ve been in the roofing business in Hampton Roads for over 25 years, and we have the knowledge and know-how for the very specific types of issues homeowners in southeast Virginia experience.

The Problem with Pipe Collars

One of the most common sources of roof leaks is probably something you never think about: pipe collars.

Take a look at your roof and you’ll notice a few small pipes sticking up in seemingly random areas. These pipes are what make it possible for your sinks, tubs and toilets to drain or flush. All of those fixtures require a single or shared pipe to exit the roof, which allows the intake of air that enables them to drain or flush. Think about a gas can and how it’s only possible to have an unrestricted flow if a secondary air valve is open. These vents, which are actually truly air intake pipes, are generally made of PVC and can range in size from 1 ¼” to 4.”

Each of these pipes passes through a pipe collar (sometimes also called pipe flashing, roof jacks or pipe boots) at the point where it exits your roof. This flashing should integrate under and over your roofing materials, creating a watertight seal. In addition to being able to withstand moisture, they must also be able to withstand heat, sun, wind, snow and ice.

By far, though, the biggest demands on pipe collars are the sun and changing temperatures. Seasonal and even daily temperature changes can cause the PVC pipe itself to move dramatically up and down as the plastic expands and contracts. Depending on the material of the pipe collar, this can cause cracking and gaps that allow water in.

Pipe Collars that need to be replaced!

Newly installed Pipe Collars

Most pipe collars can only be expected to last 7-12 years at most before running into some type of failure. Older styles use a rubber gasket that will often dry rot, crack and deteriorate. But even metal pipe collars can fail over time, especially if exposed to extreme weather. And considering that this is probably something very low on your home maintenance list, it’s likely that any problem your pipe collars run into will only come to your attention when a leak appears, at which point damage has been done to more than just the collar. The good news is that there is a way to avoid this.

Using a higher quality pipe collar material can eliminate the need for maintenance and threat of leakage. At Andrews Roofing we use a pipe collar product called The Ultimate Pipe Flashing ® for shingle roof installations and reroofing projects. This product is made by Lifetime Tool & Building Products in the USA from ultra-pure silicon and marine grade stainless steel, which means it’s virtually weather proof. This product is flexible to accommodate just about any roof slope. It’s also guaranteed for the life of your roof when properly installed by a licensed roofing contractor.

While this may seem like a small detail in the grand scheme of your home’s roof, it’s actually a really critical component in keeping your roof and interior fixtures functional and protected. Investing a little bit more in higher quality materials can save you thousands of dollars in the long run when a leak occurs from premature product deterioration.

If you think your vent pipe collars may need replacing or have noticed the signs of roof leakage, contact Andrews Roofing today. We have been helping homeowners in the Hampton Roads region protect and repair their homes for over 25 years. We have the experience and knowledge to help you choose the right products for your home and your budget, and we work with the best manufacturers in the industry to provide you with materials that will last.

Don’t Blame the Roof: Why Your Chimney May be the Cause of a Leak

Roof leaks are a homeowner’s nightmare, leading to potential damage, mold growth, and costly repairs.

While many people associate roof leaks with damaged shingles or flashing, one often overlooked culprit is the chimney. Chimneys can be a source of significant water damage if not properly maintained. But how do you know whether your leak is coming from your roof or your chimney?

How Your Chimney Can Cause a Roof Leak:

Cracked or deteriorated chimney crown: The chimney crown is the concrete or cement layer at the top of the chimney. Over time, exposure to harsh weather conditions can cause it to crack or deteriorate, allowing water to seep into the masonry and eventually into the roof.
Damaged or missing chimney flashing: Flashing is the metal strip that seals the intersection between the chimney and the roof. If the flashing becomes damaged, improperly installed, or starts to deteriorate, it can create a pathway for water to enter the roof system.
Crumbling mortar joints: The mortar that holds the bricks or stones of the chimney together can deteriorate over time due to weathering. As the mortar crumbles, gaps and openings can form, permitting water infiltration into the roof.

How to Detect a Chimney-Related Roof Leak:

Internal signs: Look for water stains, peeling paint, or discoloration on ceilings or walls near the chimney. These are often indicators of a leak. Mold growth or musty odors may also be present.
Exterior signs: Inspect the chimney for cracks, crumbling masonry, or missing flashing. Pay attention to any signs of water pooling on the roof or around the chimney after a heavy rainfall.
Attic inspection: Check your attic for signs of water damage, such as damp insulation, water stains, or rotting wood near the chimney.

Taking Steps to Repair the Damage:

Consult a professional: If you suspect your chimney is causing a roof leak, it is crucial to contact a qualified roofing professional and/or chimney specialist. Depending on the damage you may need both specialists to come in and do repairs – especially if a chimney leak has caused damage to nearby areas of your roof.
Chimney crown repair: If the chimney crown is cracked or deteriorated, it should be repaired or replaced. A chimney professional can apply a waterproof sealant or construct a new crown to prevent water penetration.
Flashing replacement: Damaged or missing flashing should be replaced with new, properly installed flashing. This will ensure a secure seal between the chimney and the roof. A qualified roofing contractor can do this repair and in some cases a chimney repair company can as well.
Mortar joint repair: If the mortar joints are deteriorating, a process called tuckpointing can be performed. This involves removing the damaged mortar and replacing it with new mortar to restore the chimney’s integrity. This should only be done by an experienced chimney and masonry expert.
Regular maintenance: To prevent future leaks, schedule regular chimney inspections and maintenance. Keep the chimney free of debris, ensure proper ventilation, and consider applying a waterproofing sealant to protect against moisture.

While chimneys provide warmth and charm to our homes, they can also become a pesky source of roof leaks if neglected. Just like other functional and structural aspects of your home, pay attention to your chimney and visually inspect it regularly. If you think it may be causing any leaks or issues, contact a professional as soon as possible before further damage is done. By addressing chimney-related issues promptly, you can protect your home and preserve its structural integrity for years to come.

If you’re not sure if your leak is coming from roof or chimney damage, contact us today. Our experts can provide an on-site inspection to help identify the issues and make a plan for repairs – whether we do them ourselves or refer you to a local chimney specialist.

Why Are Metals Roofs More Expensive?

If you’ve been considering reroofing your home, you’ve probably been researching and pricing out different options.

These days there are many more options than just a traditional 3-tab asphalt shingle. There are composite materials, walkable surfaces, wood, clay tile and metal. Of all of these materials, metal roofing is showing the largest growth in consumer interest. While metal roofs are typically more expensive upfront compared to shingled roofs, there are some good reasons why the price disparity exists and many cost benefits associated with a metal roof. Here are just a few things to consider when evaluating whether metal is the right materials for your home’s new roof.

Why so high?
So why do metal roofs have a higher upfront cost than traditional shingles?

First, the materials used in metal roofs, such as steel, aluminum, or copper, are generally more expensive than the asphalt materials used in traditional shingles. These heavy-duty materials can also cost more to manufacture and to ship. Most manufacturers have a factory applied paint finish, with a wide range of color options and some custom colors or less common colors may have an additional cost.

Secondly, they have a longer lifespan thanks to the durability of the materials used. While a typical shingle roof can be expected to function properly for 20 to 30 years, a metal roof can be expected to perform for 50 or more years with proper maintenance. This longevity significantly reduces the need for roof replacements. You may go through two asphalt shingle roofs in the lifespan of one metal roof, making the metal roof much more cost effective over time.

Thirdly, metal roofs withstand heavy winds and storms better than a traditionally shingled roof. This matters a lot in places like southeast Virginia where we encounter hurricanes, tropical storms, nor’easters and plenty of regular old severe storms at any given time of the year. While shingle roofs may be rated for up to 110 mph winds, some metal roofs are rated for 140 mph winds or even more. That’s the difference between withstanding a category two hurricane and a category four hurricane. The reduced costs in repairs over time also contribute to the long-term value of a metal roof.

Finally, metal roofs are more energy efficient, which can lead to cost savings in the long term. They reflect a significant portion of the sun’s radiant heat, reducing the need for air conditioning during hot summer months. This reflective property, coupled with proper insulation, can help lower cooling costs and decrease energy consumption. Moreover, some metal roofs are designed with integral air gaps or coatings that enhance their insulating properties, further reducing heating costs in colder climates. These energy-saving advantages contribute to lower utility bills and, ultimately, a return on investment for homeowners who choose metal roofs.

So yes, metal roofs are a steeper upfront investment in your home. But the cost has long-term benefits that can outweigh the initial cost disparity. The extended lifespan, reduced need for roof replacements, energy efficiency, and consequent cost savings make metal roofs a wise and financially sound choice for homeowners seeking durability, sustainability, and long-term economic advantages.

Traditional vs. Architectural Shingles

Asphalt shingles have long been the most popular roofing materials in residential structures, but the shingle itself has changed over time.

These days there are two basic types of asphalt shingles to choose from: the older, 3-tab style shingle and the newer architectural shingles. While architectural shingles are a newer style, they have become more widely used in new roof construction and roof replacements. Despite both being made from the same basic material, there are several key differences between the two styles.

Appearance: Architectural shingles, also known as dimensional or laminate shingles, have a more textured, three-dimensional look compared to standard 3-tab shingles. They are designed to mimic the appearance of natural materials like wood or slate and can enhance the curb appeal of a home. 3-tab shingles lie flat against the roof decking with little to no variation or texture.
Thickness and Weight: Architectural shingles are generally thicker and heavier than 3-tab standard shingles. They are composed of multiple layers of asphalt and have a fiberglass mat core. The added thickness and weight contribute to their durability and longevity.
Durability and Warranty: Due to their multi-layered construction, architectural shingles tend to be more durable and have a longer lifespan than standard 3-tab shingles. They are more likely to withstand harsh weather conditions such as the heavy rain, wind, and other severe storm conditions we often see in Southeast Virginia.Architectural shingles also have better wind resistance compared to 3-tab shingles. The multiple layers and the heavier weight help them stay in place during strong winds. They are often rated to withstand winds of 110 mph or more, while standard 3-tabs may be rated for lower wind speeds. Many architectural shingles come with warranties ranging from 30 to 50 years, whereas standard 3-tab shingles usually have shorter warranties.
Cost: Architectural shingles are typically more expensive than standard 3-tab shingles due to their enhanced appearance, durability, and longer lifespan. However, in the Tidewater Roads region, based on the average size of homes, architectural shingles are typically only about $100-500 more per job, making them well worth the value for the additional years you can expect to get from them.
Installation: The basic approach to installing architectural shingles is not that much different than traditional 3-tab shingles, but they are heavier and have a layered design that requires professional installation by a licensed roofing contractor. Always make sure any roofing professional you use is licensed and insured before signing any contracts or work agreements and get all warranty information on both the material and workmanship in writing.
Availability: Standard 3-tab shingles have been widely used for many years and are readily available in various colors and styles. However, as architectural shingles have gained popularity over time, they are also now widely available and manufacturers are offering a wide range of options and colors to suit different architectural styles and preferences.

If you’re building a new home or considering replacing your roof, take some time to consider the materials you will be investing in. Of course, you have to balance a budget, but it’s also just as important to consider the durability of your investment in the storm and hurricane-prone area in which we live in addition to the look you want your home to have.

If in doubt, give Andrews Roofing a call.
