Your roof is more than shingles and nails—it’s your home’s first line of defense against Northern Virginia’s unpredictable weather. From humid summers to icy winters, your roof quietly takes the brunt of every storm, heatwave, and gust of wind. But how do you know when it’s time for a roof replacement instead of another patch-up? Ignoring the warning signs can lead to leaks, structural issues, and costly repairs down the road.
At Mars Roofing, we believe homeowners deserve peace of mind. That’s why we’ve put together this guide to help you recognize the early (and late) signs your Northern Virginia roof may need replacement.
1. Shingle Damage You Can’t Ignore
Shingles are designed to protect your home by creating a waterproof barrier. When they fail, your roof is no longer doing its job. Some red flags include:
Curling or buckling shingles – A classic sign your roof is aging. Curling edges allow water to seep underneath.
Missing shingles – If storms regularly strip shingles off, it’s time to consider whether your roof is holding up.
Cracked or brittle shingles – Heat and UV rays wear shingles down until they lose flexibility.
Granule loss – Check your gutters. If you see shingle granules collecting there, your roof is breaking down faster than it should.
If these problems cover more than just a small patch, replacement may be the smarter long-term choice.
2. Persistent Leaks or Water Damage
A leaky roof is more than an inconvenience—it’s a threat to your home’s structure. In Northern Virginia, frequent rainstorms and melting snow test even the best roofing systems. Signs of deeper trouble include:
Water stains on ceilings or walls
Mold or mildew in your attic
Damp insulation that no longer does its job
A few small leaks can sometimes be repaired. But if water intrusion keeps coming back, it usually means your roof system has reached its limit.
3. Age of Your Roof
Roofs don’t last forever. Most asphalt shingle roofs are designed to last 20–25 years, while premium materials may last longer. If your roof is pushing past its lifespan, even if it “looks fine,” problems are likely around the corner.
Homeowners in Northern Virginia face extra wear and tear because of rapid temperature shifts. One day it’s humid and stormy, the next it’s icy cold—those changes cause expansion and contraction that ages roofing materials quickly.
If your roof is over 20 years old, schedule an inspection. Replacing before serious damage happens can save thousands.
4. Sagging or Structural Issues
A sagging roof is never a cosmetic issue—it’s a safety concern. Sagging usually indicates trapped moisture, weakened decking, or compromised rafters. You may notice:
A dip in the roofline from the curb
Uneven surfaces when looking from the attic
Cracks forming in the interior drywall
This is one sign you don’t want to put off. A sagging roof requires immediate professional
5. Rising Energy Bills
Your roof plays a huge role in regulating your home’s temperature. When it’s no longer sealing properly, your HVAC system works overtime. If you’ve noticed:
Higher cooling costs in the summer
More expensive heating bills in winter
…it could be your roof. Worn shingles, poor ventilation, or compromised insulation allow air to escape, driving up costs. A new roof with modern materials improves energy efficiency and comfort.
6. Exterior Red Flags
Sometimes the clues are visible before you even step inside. Keep an eye out for:
Damaged flashing – Around chimneys, vents, and skylights, flashing should be secure. If it’s rusted or missing, water will find a way in.
Clogged or broken gutters – Overflowing water may indicate roofing materials shedding excessively.
Moss, algae, or mold growth – A sign of trapped moisture and poor drainage.
These issues often go hand in hand with larger roofing failures.
7. Frequent Repairs Becoming the Norm
Occasional repairs are normal. But when you’re calling a roofer every season, the costs add up quickly. Instead of pouring money into patchwork fixes, consider the value of investing in a complete roof replacement. It often provides a more permanent and cost-effective solution.
Quick Reference: When It’s Time for a New Roof
Here’s a simple checklist to help you decide if replacement may be on the horizon:
Your roof is 20+ years old
Large patches of shingles are curling, cracked, or missing
You see daylight through attic boards
Water stains keep reappearing despite past repairs
Roofline shows sagging or dips
Energy bills have spiked without another explanation
Repairs are becoming a frequent expense
If you checked off several of these, it’s time to consult a roofing professional.

You know your roof is on its last legs—maybe you’ve spotted curling shingles, a few leaks, or that one neighbor who keeps giving you the look because your roof is bringing down the block’s curb appeal. So, you’ve decided it’s time for a roof replacement. Great! But now comes the next big question: how long does it take to replace a roof?
The good news? A roof replacement doesn’t have to drag on for weeks. In fact, most homes can get a brand-new roof in just one to two days. The not-so-good news? Weather, roof size, and unexpected repairs can throw a wrench in the timeline. If you’re in Maryland, where we get everything from scorching summers to unexpected snow, timing can be tricky.
At MARS Roofing, we’ve replaced enough roofs to know that homeowners want two things: speed and quality. In this guide, we’ll break down what affects the timeline, what to expect from start to finish, and how to prepare for the smoothest roof replacement possible.

What Affects How Long a Roof Replacement Takes?
Most standard residential roof replacements take one to two days, but several factors can extend or shorten that timeline. Here’s what plays a role.
1. Roof Size and Complexity
The bigger and more complicated the roof, the longer the job will take. A simple, single-story home? One day, easy. A multi-story house with steep slopes and dormers? Add an extra day or two.
Small homes (1,000-1,500 sq. ft.): 1 day
Medium-sized homes (1,500-3,000 sq. ft.): 1-2 days
Large homes (3,000+ sq. ft.): 2+ days
2. Roofing Material Selection
Some materials are quick and easy, while others take time and precision.
Asphalt Shingles: The fastest option—usually 1-2 days
Metal Roofing: Requires extra measuring and fastening—2-3 days
Slate or Cedar Shake: More detailed work—3-5 days
Flat Roofs (TPO, EPDM, PVC): Varies based on size—2-4 days
If speed is your priority, asphalt shingles are the way to go. But if you want a lifetime investment, metal or slate might be worth the wait.
3. Maryland Weather
Let’s talk about the one thing none of us can control—Maryland’s unpredictable weather.
Ideal conditions: 50-80°F with clear skies = fast installation
Delays: Rain, high winds, and snow can pause work for safety reasons
Extreme heat: Slows down workers, leading to longer breaks and a slightly extended timeline
At MARS Roofing, we track the forecast to schedule jobs when the weather is on our side.
4. Hidden Repairs
Here’s a common scenario: We tear off the old roof and find unexpected problems.
Rotten or water-damaged decking
Structural issues from previous poor installations
Mold or mildew hiding underneath
These fixes add extra time, but skipping them would shorten your roof’s lifespan. We always perform a thorough inspection before starting, so there are fewer surprises.
What to Expect During a Roof Replacement
If this is your first time replacing a roof, here’s a breakdown of what actually happens.

Have you determined it is time to replace your roofing system this year? Perhaps you have noticed areas of damage, or the constant repairs are becoming too repetitive. Wind, hail, and tornadoes can cause complications with our roofs in the Maryland area. How much does it cost to have a roof replaced in Maryland?
The average cost of a roof replacement in Maryland is $650 to $1,100 per square foot. This cost depends on a variety of factors including the size of your home, the roofing materials used, and the installation costs of the roofing contractor in Maryland.
Here is a rough estimate of the breakdown:
10 square roof: $6,500 to $11,000
15 square roof: $9,750 to $16,500
20 square roof: $13,000 to $22,000
25 square roof: $16,250 to $27,500
30 square roof: $19,500 to $33,000
Roofs are measured in “squares”. A 100-square-foot area is considered 1 square in roofing terms. To simplify, the amount of material needed to cover 100 square feet of roof area is equal to 1 square of roofing material. So, as an example, if a roof surface area is 2000 square feet, the contractor would figure 20 squares. You can approximate how many squares your home is by dividing the square feet of your roof area by 100. For a free inspection of your particular home, contact MARS Roofing at (240)540-4580

Your roof is more than shingles and nails—it’s your home’s first line of defense against Northern Virginia’s unpredictable weather. From humid summers to icy winters, your roof quietly takes the brunt of every storm, heatwave, and gust of wind. But how do you know...
You know your roof is on its last legs—maybe you’ve spotted curling shingles, a few leaks, or that one neighbor who keeps giving you the look because your roof is bringing down the block’s curb appeal. So, you’ve decided it’s time for a roof replacement. Great! But...
Did Hurricane Ida in 2021 cause damage to your roof? Are you still deciding what you are going to do in repairing it? Have other storms since then caused more damage, creating larger issues? The fear of cost and the stress behind getting a new roof can drive us to put it off for another day.
The cost of an asphalt shingle roof replacement in Maryland is approximately between $7,500 and $15,000, based on a 1500-square-foot home.

Besides storm damage, what are other reasons to have your roof replaced?
Missing, broken, or torn shingles
Curled shingles on the edges
Heavy growth of mold and mildew on the shingle surface
Shingles that have lost granules
Evidence of water damage in your home from a leaking roof
Spongy areas in the shingles
When you call for a free inspection, what are some factors that must be considered as components of a quote on a new roof? Here is an essential list.
Roof size
Type of roofing material
Labor
Disposal of old material
Pitch, overhang, flashing
A trustworthy company will explain each of these items to you in detail and help you understand what they mean. MARS Roofing appreciates taking the time to educate you on each of these details so there is no confusion.
Besides the above list of items that make up the initial cost, other considerations should be discussed.
Underlayment Repair
Underlayment has a very important job and must be inspected when a new roof is installed. Here is the key point of underlayment and its purpose:
It protects the plywood decking from exterior elements
Shed moisture to help prevent mold and mildew
Prevents leaks from entering the home
Maintains a quality barrier between the actual roof and the decking
Disposal of old material
In most cases, the old roofing material must be removed and discarded before the new can be installed. Please make sure your roofing company places tarps around your landscape and property to ensure simple cleanup and protection of your home. Ask if there are additional fees for the removal and disposal of the old roofing material.
Gutter Inspection
Gutters are a key component of a quality working roofing system. The main purpose of a gutter system is to effectively collect rainwater from your roof, and channel it to the ground through a downspout. When the gutter system fails, the water will seep through holes, and areas of rust, causing potential ice dams in the winter. Those icicles can be pretty in pictures, but they have not welcomed sights on your rooftop.
Our process as a roofing contractor is smooth and simple. You can turn your focus on the things that are most important to you, and leave the roofing job to us! We, at MARS Roofing, a Maryland roofing company, treat your property as if it were our own. Our experts will work with you to find the best solution for your needs.
