A leaky roof can be more than a pain, it can cause real structural damage and should be dealt with as soon as possible. With that being said, most small cracks, leaks and damaged shingles can be repaired rather easily and without the help of an experienced professional; especially with the support of a few tips and resources.
Though if your roof has any considerable damage or large holes it’s best to consult with a professional roofer who can give you a sound opinion and quote on how much it will cost to fix the issue.
8 Tips to Repair Your Leaking Roof
1. Replace any missing or damaged shingles
Once you are on the roof ensure you review it for any missing or damaged shingles. You will want to note every one and repair them – depending on how damaged the shingles are you will either have to replace them all together or use roof sealant to fix cracks which we will cover in a later tip. Don’t forget to check your roof thoroughly as you will want to ensure you do not miss any shingles.
2. Repair all vent boots
Repairing your roof doesn’t just mean the shingles. You should also review your vent boots and any roof vents to ensure there are no cracks forming around their bases, which could cause leaks.
These typically form in the rubber gaskets or across any seams in the welding which are more susceptible to corrosion over time. If you do discover any damage you will need to either replace the vent or hire a professional to repair it. If left this type of damage can easily spread into large leaks that can impact the roof board and structure beneath it.
3. Check for roof damage above water marks in your ceiling
Where there is water damage inside there is likely a damaged roof outside. To find these locations mark where you have ceiling damage than go check your roof in the surrounding areas. You may find some shingles requiring replacement or damaged wood that may require the work of a professional to fix. If you can fix the shingles do so yourself than consider giving your ceiling inside a new coat of paint to cover the damage (if it’s only surface level).
4. Check the step flashing, edges and base of your chimney for any leaks
Take a quick look around the chimney, if you see any rust, damaged bricks or corroded step flashing you will want to take note. These sections can be more difficult to repair and often require the help of a professional, this especially the case if there is any damage to the chimneys brickwork.
5. Repair any damaged siding and trim
It’s not just your roofing that can lead to a leaky roof, siding, trim and damaged gutters can also lead to water entering your home. To fix these types of issues you will need to replace and or repair the damaged section and re-caulk it appropriately. While doing the repairs it can also be worth it to fix any old caulking that may have become damaged or dry. This can help ensure your siding will remain watertight for the long term.
6. Fix all small holes
Whether a tree branch fell on your roof, or you have storm damage – If you have any small holes in your roof you will want to deal with them right away. These holes can typically be repaired quite easily using some roof flashing, a new shingle, and some roof cement to ensure the flashing stays in place. If the hole is larger than a softball you may want to consider consulting with a professional.
7. Look for discoloration and damaged shingles to identify problem areas
If your shingles have started to discolour and appear damaged then it may be time to consider a new roof. A good rule of thumb is to replace your roof at least every 20 years, any longer and the shingles tend to really show the wear and tear of the outdoors. This is important as the discoloration and damage can also be a marker of further issues beneath the surface such as molding roof boards or even structural damage caused by long term leaking.
With that being said, if the discolouration is minor or the damage is minimal then you can also choose to repair the shingles yourself and extend the life of the roof a bit longer.
8. Use roof sealant to fill small cracks
Roof sealant can be a real help when you just have tiny cracks to fix. Grab some and check your shingles for any splitting or curling that may cause cracks. If you notice any that may require patching make sure you apply a generous amount and follow the manufacturers directions. If the cracks extend beyond the shingles into the roof boards then you will want to consult with a professional. These types of cracks can lead to structural issues if left long enough and can also add the potential for pests getting in and wood rot.
