How to Tell If Your Roof Needs Repair or Full Replacement

Introduction

For most homeowners in Arlington VA, their roof is not something that they think about until there is a problem. Water stain on the ceiling. After a storm, some shingles were scattered across the yard. A draft from the attic, not present last winter.

Next there's the big question. Should I get a repair or a complete replacement?

It's not always easy to see. And the wrong call costs money either way. Fixing a roof that really needs to be replaced is only a postponement of the problem. If the roof was just in need of a patch, replacing it is a waste of thousands of dollars that you didn't need to spend.

This guide explains what to consider, what the signs actually represent, and how Arlington's housing stock and climate come into play when making a decision.

Your Roof's Age Is the First Factor to Consider

Age is the single most reliable starting point.

Most homes in Arlington and Northern VA are roofed with asphalt shingles. The average life of standard three tab shingles is about 20 years. Manufacturers such as GAF, Owens Corning and CertainTeed offer architectural shingles that can last 25 to 30 years in normal conditions.

Here is the thing. Roofing materials are truly challenging in Northern Virginia. Winter is a time of repeated freeze-thaw cycles. Cold nights, wet springs and humid summers cause shingles to age more quickly than milder climates. The roof was installed in the early 2000s in Arlington, and has been beaten up over the years.

What the Age Range Tells You

If you can't determine the age of your roof, look at your home inspection report from the time of purchase. There may also be previous replacement dates in Arlington County building permit records.

Signs That Indicate That the Problem Needs to Be Fixed

Not all roof issues require a complete roof removal. These are typically the indications that a focused repair can remedy the problem.

Damage Is Limited to One Area

Shingles are lifted by wind in a particular area. One section is damaged by a broken branch. A chimney or skylight flashings loosen. If the damage is limited to a small area, a professional roofing company can repair that section without any need to work on the other parts of the roof.

Your Roof Is Still Young

If the system has been in place for the past 10-12 years, and the overall shingle field appears healthy, you are not close to end of life. If one part of the roof is damaged, it doesn't necessarily indicate that the entire roof is compromised.

You Have One Isolated Leak

If one leak is found and it is due to a leaking flashing, a broken pipe boot or a small area of missing shingles, then it is a repair situation. A single source, a single fix.

The Surrounding Shingles Are Intact

Sometimes shingles blow off in a small area after a storm. If the remaining shingles are still flat, have good granules and are not cracked or curled, then replacing the missing shingles is a viable solution.

Signs That Indicate Full Replacement

These signals will only give you a little bit of time before you're talking about the same thing again.

The Roof Has Reached Over 20 Years and Is Experiencing Multiple Problems

This is the most common situation on older Arlington neighborhoods. The houses in places such as Ashton Heights, Dominion Hills and Cherrydale date from the 1950s to 1970s. Their original roofs, or even first replacements, are well past their service life.

If a roof is this old, it will leak at other points too. Repairing one spot does not usually resolve the issue.

You Are Finding Granules in Your Gutters

A major indicator of an old roof is granule loss. Granules cover the underlying mat to prevent it from being damaged by the sun's rays on asphalt shingles. Once these granules begin to fall off, the shingles get brittle and crumble easily.

Check your gutters after heavy rain. When there is a lot of dark grit around the downspout outlets, it's a sign that your shingles are not doing well.

Shingles Are Curling, Buckling, or Cupping

Curled edges and buckled shingle surfaces indicate moisture damage, inadequate attic ventilation, or degradation of the shingle. When shingles lose their flatness they are unable to shed water properly.

This rarely appears in just one small area. If you notice curling on the roof field, it's a systemic issue, not a localized one.

You Are Seeing Sagging Sections

Structural issues include a sagging roofline. It refers to leaky roof decking, broken rafters, or moisture damage over the years that has weakened the layer under the shingles.

This is not a cosmetic problem. If the roof is sagging, it is a serious problem and will almost always necessitate a complete replacement, including the decking layer.

Several Leaks in Various Areas

A single leak is an issue. If two or three leaks are found in different sections of the roof over a short period, it is an indicator that the entire roof is in trouble. From then on, it's a game of finding new issues to fix. You fix one location and another appears 6 months later.

Light Is Visible Through Your Attic

On a sunny day, enter your attic and gaze upwards. If daylight can be seen through the roof boards anywhere, the roof has holes in it where water and cold air are seeping in. This penetration typically indicates that the decking and underlayment is already damaged.

Your Energy Bills Have Increased Unexpectedly

When a roof is failing, the underlayment is often compromised and attic insulation is not installed properly, causing heat to escape the home during the winter and enter in the summer. If your heating and cooling bills have increased for no apparent reason, your roof might be to blame.

The 50 Percent Rule Every Arlington Homeowner Should Know

Here is a practical framework that is used consistently by experienced roofing contractors.

Replace roof if repair costs more than 50 percent of replacement costs. The reasoning is simple. You're paying a considerable amount of replacement cost without a new roof, new warranty, and a full lifespan.

For instance, if the full replacement is estimated to cost approximately 14,000 dollars, and the proposed repair is estimated to cost 7,500 dollars, the figures indicate that replacement is the best option. It costs a little more initially but you'll save yourself 25 years instead of a patch.

Before making your decision, ask your contractor to explain both numbers to you.

How Northern Virginia's Climate Affects This Decision

Homeowners in milder climates don't have the same roofing challenges as Arlington or the rest of the Northern Virginia area.

The Freeze-Thaw Cycle

Water expands when it freezes. In Arlington, temperatures drop below freezing at night and climb back above during the day, repeatedly through winter. Each time the water becomes frozen and expands, the gaps between the shingles and the roof become slightly larger.

This can cause a lot of damage to shingles over a number of winters. This is the 200th cycle for a 20-year-old roof in Northern Virginia.

Ice Dams

When the attic is poorly ventilated and the heat is lost through the roof, snow will melt and refreeze at the eaves. This creates ice dams which cause water to back up under the shingles and into the roof deck.

If you have experienced ice dams, get your roof and attic ventilation assessed thoroughly. Damage may be more severe than can be seen from the outside.

Aging Housing Stock

Many of Arlington's houses were constructed from the 1940s through the 1970s. These properties are characterful, but also have original or previously replaced roofing systems. Many are located under trees that drop leaves throughout the year and cause a moist environment on the roof surface.

If your house is in this category, consider replacing it sooner rather than later.

What a Professional Roof Inspection Actually Tells You

A competent inspection by a licensed Virginia contractor is more than a ground-level visual inspection.

The shingle field condition, flashing at all penetration points, ridge cap and drip edge, gutter attachment and drainage, soffit and fascia condition and attic ventilation are all covered in a thorough inspection. The contractor should also look for soft spots in the decking which may be a sign of moisture damage under the deck.

In Arlington County, all replacement work must have a building permit. A good contractor takes care of this for you. Beware of any company that claims to be able to bypass that step.

Check for contractors who are licensed by DPOR in Virginia and have liability insurance and workers compensation insurance. These are not extras but essential. These are mandatory requirements.

Questions to Ask Before You Decide

Before making either choice, find out the answers to these questions from any contractor you're considering.

If a contractor can provide clear, non-threatening answers to these questions, they're a good choice to trust.
