Key Takeaways

  • Replacing Missing or Damaged Shingles – Shingles protect against leaks, so replacing a few damaged ones can prevent bigger issues. Lift the surrounding shingles, remove the old one, and secure a new shingle with nails and sealant. If large sections are missing or the roof deck is damaged, call a pro.

  • Sealing Small Roof Leaks– Even tiny leaks can lead to mold and rot. If you find water stains or damp insulation, apply roofing sealant or waterproof tape for a quick fix. If the leak persists or involves flashing or a skylight, professional repair is best.

  • Cleaning and Repairing Gutters – Clogged gutters can cause water damage to your roof and foundation. Clear out debris, flush with water, and secure any loose sections. If gutters are sagging, misaligned, or causing fascia rot, a pro should handle the repair.

  • Resealing Flashing Around Roof Penetrations – Flashing prevents leaks around chimneys, vents, and skylights. If it’s cracked or pulling away, apply roofing sealant to reseal it. If it’s rusted, detached, or still leaking, a professional replacement is needed.

  • Patching Small Roof Punctures – Small holes from debris or wildlife can let in water and pests. Patch them with roofing cement, reinforce with fabric, and seal with another cement layer. If multiple punctures or deeper damage is present, call a roofing professional.

Roof repairs can feel overwhelming, but not every issue requires an emergency call to a roofing contractor. Some fixes are totally manageable as DIY projects—if you know what you’re doing. The key is understanding which repairs are safe to handle yourself and which ones are better left to the professionals.

Before we get started, a quick safety reminder: Always use a sturdy ladder, wear nonslip shoes, and have someone nearby in case you need assistance. If your roof is too steep or high, don’t risk it—call a pro. Now, let’s dive into five roof repairs you can tackle yourself and when it’s time to bring in an expert.

1. How to Replace Missing or Damaged Shingles

Shingles play a crucial role in protecting your home from water damage, so even a few missing or broken ones can lead to leaks or structural issues. Addressing shingle damage early helps prevent costly repairs and keeps your roof in top shape.

How to Spot the Issue

After a storm, take a quick look at your roof for cracked, curled, or missing shingles. You should also check your yard and gutters for loose shingles or granule buildup—both are signs your roof may need attention.

DIY Fix: Swapping Out a Shingle

  1. Carefully lift the shingles above the damaged one.
  2. Remove the nails holding the old shingle in place.
  3. Slide in a new shingle, secure it with nails, and seal the edges with roofing sealant.

When to Call a Pro

  • If large sections of shingles are missing.
  • If damage extends beyond the surface, affecting the roof deck.

Swapping out a few shingles is an easy way to keep your roof watertight and stop small problems from turning into big ones. Plus, regular inspections make it easier to catch minor damage early, saving you from a costly roof replacement down the road.

2. The Importance of Fixing Small Roof Leaks

A small roof leak might not seem like a big deal at first, but it can quickly turn into a costly headache with mold, rot, and structural damage. That’s why it’s always best to tackle it as soon as possible.

How to Find a Leak

Finding a roof leak is easier if you know what to look for. After heavy rain, check your ceilings and walls for water stains, as they’re often the first sign of trouble. It’s also a good idea to inspect your attic for damp insulation, mold, or even visible drips, which can point to a leak before it gets worse. If you’re unsure, learning how to spot the signs of water damage can help you catch issues early before they escalate.

DIY Fix: Sealing a Minor Leak

  • Apply roofing sealant or waterproof tape over small cracks.
  • Use a tarp for temporary protection if a quick fix isn’t possible.

When It’s Time to Call a Pro

  • If the leak persists after sealing.
  • If the leak is coming from a chimney, skylight, or flashing—these require expert repair.

Even a small leak can turn into a major problem if left unchecked. Catching and sealing it early can save you a lot of trouble, but if you’re not sure where the leak is coming from or the damage is spreading, calling a pro is the safest bet.

3. Clearing and Repairing Your Gutters 

Gutters play a crucial role in directing water away from your home. When they get clogged, water can back up, damaging both your roof and foundation.

Signs of Gutter Problems

Your gutters might not be something you think about often, but when they start acting up, the warning signs are hard to miss. Here are some key indicators that your gutters need attention:

Overflowing Water During Rainstorms

If you notice water spilling over the edges of your gutters instead of flowing smoothly through the downspouts, there’s a problem. This could be due to clogs from leaves and debris, improper slope, or a blockage in the downspout preventing proper drainage. Left unchecked, overflowing water can lead to foundation issues, landscape erosion, and even leaks in your home.

Detached, Sagging, or Cracked Gutters

Gutters are meant to stay securely attached to your roofline, so if you see sections pulling away, sagging in the middle, or showing visible cracks, it’s time for a fix. Sagging gutters usually mean they’re clogged and holding too much weight, while cracks or separations can cause leaks that lead to water damage on your siding or fascia. In extreme cases, a failing gutter system can even contribute to structural issues in your home.

DIY Fix: Cleaning and Securing Gutters

  • Clear out leaves and debris by hand or with a gutter scoop.
  • Flush gutters with a hose to check for blockages.
  • Reattach any loose sections with gutter hangers or screws.

When to Call a Pro

  • If your gutters are severely damaged or improperly sloped.
  • If fascia boards (the wood behind the gutters) are rotting.

A little gutter maintenance goes a long way, and it’s one of those small tasks that can save you from big, expensive headaches down the road. By keeping your gutters clear of leaves, debris, and buildup—and considering installing some gutter guards for added protection—you’re ensuring proper drainage and protecting your home from water damage.

4. Resealing Flashing Around Roof Penetrations

Flashing is the thin metal installed around chimneys, vents, and skylights to prevent leaks. If it’s cracked or lifting, water can seep in and cause some serious damage.

Signs Your Flashing Needs Repaired

  • Water stains around chimneys, skylights, or vents.
  • Rusted, lifted, or cracked flashing.

DIY Fix: Applying Roofing Sealant

  • Clean the area and remove old, loose sealant.
  • Apply a fresh layer of roofing sealant along gaps and cracks.

When to Call a Pro

  • If flashing is completely detached or rusted through.
  • If sealing doesn’t resolve the leak, as the flashing may need full replacement.

Properly sealed flashing keeps water out and prevents damage. While minor resealing is easy, complex flashing repairs should be handled by a pro.

5. Patching Small Holes or Punctures

Even a small hole in your roof can lead to bigger problems than you might expect. Water can seep in, causing mold and rot, while pests and drafts make your home less comfortable. Spotting and sealing these punctures early helps you avoid costly damage and keeps your roof in good shape.

Common Causes of Roof Punctures

  • Storm debris, falling branches, or hail.
  • Wildlife damage (squirrels, birds, raccoons).

DIY Fix: Quick Patching

  • Apply roofing cement over the hole.
  • Reinforce with a small piece of roofing fabric for extra protection.
  • Cover with another layer of roofing cement to seal it.

When to Call a Pro

  • If the hole exposes significant underlying damage.
  • If multiple punctures indicate deeper structural issues.

Taking care of small holes right away prevents bigger problems down the line. A simple patch job now can save you from expensive repairs and keep your roof protecting your home for years to come.
