How to Fix a Leaky Roof

Fixing a leaking roof isn’t rocket science – if you know what you’re looking for. Detecting the source of a leak in the first place may be the most difficult aspect of repairing a leaky roof.

Finding a Roof Leak

Finding the actual location where a roof is leaking is difficult. Water may seep through a roof in one spot and run down before it drips through a ceiling.

Yet finding even the smallest leak in a roof is critical since early leak detection can prevent an entire roof from going bad. Experts recommend assessing a roof first of all to determine where a potential leak could be located.

According to a case study done on Minneapolis homes by Kuhl’s Contracting Incorporated, roof leaks can commonly occur in the following areas:15

  1. Ridge: Watch for uplifted or loose material.
  2. Vents: May leak due to damage from animals, storms, or poor installation.
  3. Valleys: Very unlikely to leak in this area.
  4. Plumbing or HVAC Vent Pipes: May leak in both cold and warm seasons.
  5. Rake Edge Roofing Material: May cause leaks inside the house from wind-driven water.
  6. Windows: Window leaks may be caused by roof leaks.
  7. Step Flashing: May leak due to improper installation or wind-driven rain.
  8. Bathroom/Kitchen Vent Hoods: May leak due to poor installation.
  9. Dormer Flashings: May leak if flashing is not properly installed behind siding.
  10. Gutters: Full or improperly sloping gutters may leak water into a home in winter or summer.
  11. Chimney Caps: May leak through onto ceilings or walls.
  12. Chimney Siding: Water can leak through wood or stucco chimney siding to drip onto a ceiling.
  13. Flue Penetration Joint: May leak water into a home due to poor sealing.
  14. Saddle: Leaking is very common.
  15. Step Flashing Along Chimney: May leak often due to wind-driven rain.
  16. Uncapped Furnace Flues: Will leak water directly down a flue.
  17. Storm Collar: May leak because of failed caulking after 10 years.
  18. Cone Flashing: May leak around the base of furnace flues on rare occasions.

Common areas of the roof for a leak to occur.

For more serious roof leaks, it is important to call in the professionals for help. However, if you’re able to quickly detect the source of a roof leak in one of the many areas listed above, you can repair the roof yourself with the help of a ladder:

Steps to Fixing a Roof Leak

Step 1:

Crawl into your attic wearing the appropriate safety gear.

Step 2:

Locate the source of the leak based on dripping water or discolored, stained wood.

Step 3:

Wearing non-skid shoes, use a ladder to climb onto the roof.

Step 4:

Locate the leaking area of the roof above the stains in the attic.

Step 5:

Evaluate roof flashing around chimneys, valleys, walls, and skylights for gaps, cracked caulking, and loose nails.

Step 6:

Remove corrosion and dirt from damaged flashing with a wire brush; reattach loose nails, if necessary, with a hammer.

Step 7:

Scrape old caulking from around flashing with a metal scraper; use a zinc-based primer to spray flashing with a protective coating.

Step 8:

Allow the primer to dry and spray two coats of rust-resistant metal paint over flashing.

Step 9:

Once each coat of metal paint dries, use a putty knife to apply urethane roofing cement in gaps between shingles and flashing.

Step 10:

Smooth roofing cement with a putty knife and allow to dry completely
