The source of most roof leaks is hard to find since they typically originate away from where the leaks show up. Here is how you can find and fix a leaky roof yourself. However, it is always a great idea to hire a roofing contractor in Dayton OH since roof leaks could be a sign of a deeper problem that may require a professional repair.
Finding the location of a roof leak
To find the source of your leaky roof isn’t that simple as finding a wet patch on the ceiling. Often the position of the actual leak is not where the water ends up staining your wall. Water can enter your roof from one end of your house and drip through insulation before soaking into the feeble spot of your ceiling.
Water often seeps in through broken, worn, or missing shingles; where nails have become loose or through poorly sealed or corroded flashings around vents, chimneys, or leaky skylights or along the intersection of roof planes.
Here are some tips to find a roof leak:
- Visually inspect your roof from outside. Begin
from the parts of the roof that are higher than the position of any stains
inside. If you spot any damaged spots on shingles, tiles, or corrugated sheets,
this could be the location of a leak. - If you notice water spots under your roofline
on exterior walls, it could mean that your flashings may have been damaged and
need to be repaired or replaced. - From inside of your home you can look for
peeling paint, brown, yellow or grey stains, moisture marks, these are all
signs of a roof leak. - Head to the attic to get a better view of the
underside of the roof and always carry a flashlight to examine roof. Look for
areas that are darker than the surrounding sheathing. In case there has been no
rain recently, identifying moist spots can be a little difficult. You can look
for a patch of mold which thrives on moisture or damp beams chances are that
that could be the source of your leaky roof.
Quick Fix for a Leaking Roof: Emergency Steps
If water is actively leaking into your home, here’s what to do first:
1. Move furniture and valuables – Protect your belongings from water damage.
2. Contain the water – Use buckets or tarps to catch drips.
3. Poke a small hole in sagging ceiling drywall – This prevents water from spreading and causing further damage.
4. Use a plastic sheet or tarp on the roof – Secure it with nails or bricks to prevent further water intrusion.
Ways to fix a leaky roof
Once you have identified the location of the leak, you might be able to fix it with a quick-drying silicone-based sealant, or by placing a lead flashing or a small sheet of metal over the damaged shingle or roof tile. In case your gutters are the issue then simply cleaning the debris and repairing or replacing any damaged sections could solve the issue.
Another common issue with leaks is that it often happens as a result of damaged or old caulk. You can dig around the damaged area with a putty knife and when you identify spots that are corroded or rotten you can add more caulk to seal the area. However, this is not a long-term solution and extensive damage to the dormers or walls should be looked at only by roofing contractor Dayton OH.
Please keep in mind that the exact methods of roof leak repair depend upon the roofing material and its construction.
Temporary Roof Fixes: What Works Best?
If you can safely access your roof, consider these temporary roof fixes:
How to Repair a Leaking Roof from the Inside
Sometimes, you can’t get to the roof immediately. In those cases, try these inside fixes:
1. Locate the Leak; check your attic with a flashlight and follow the water trail to the source.
2. Apply Roofing Cement; if you find a small hole, use roofing cement or a patching compound to plug it temporarily.
3. Use a Water-Resistant Sealant; silicone-based sealants can be applied to small leaks from the inside.
4. Place a Tarp Over the Leak from the Attic; if water is still entering, staple or nail a tarp to the affected area in the attic to redirect water.
