How to Fix a Hole in the Roof?


When a metal roof system is installed properly, its life expectancy is second to none. Asphalt shingles last, on average, about 20 years, composite shingles about 25 years, and wood shakes or shingles about 30 years. On the other hand, aluminium or steel roofs can easily last 50 years or more, and zinc roofs have been known to last well over 100 years.

But no building material, especially one that faces the constant weather battering, lives forever. Like all roofing systems, a metal roof requires regular maintenance and repair. Any roofing repair can be a hit or miss proposition. Done properly, repairs can last as long as the roof system itself. Done improperly, those same repairs can quickly break and fail, leaving the homeowner or building owner with a recurrent or constant leak. A recurring leak condition can be aggravating, but more serious is the interior damage and mould growth it can cause. It is always best to fix a roofing problem quickly and correctly. Repairs to a metal roof system can be complicated. Metal roofing repairs are prone to premature failure because the patched area may have a different expansion and contraction rate than the surrounding metal. This difference in expansion and contraction between the two products places stress on the repair, leading to cracking, splitting, and ultimately, failure of the patch.

The following is a recommended process for repairing a hole in a metal roof system. It should work for nearly any type of metal roof, assuming you select patching material that matches the metal style used in your roof.

Most of the tools and materials you’ll need can be found at any home centre or hardware store, but you may need to seek some of these items from a roofing store that carries a range of roofing materials and repair products. Take a look at our range of roof repairs Melbourne.


Have you noticed an irregularity with your home, which you think might be related to your roof? Things like mould on your ceiling or a leak? The reason could perhaps be that you need to replace some shingles. There might have been some damage to your roof due to weather conditions or animals. Whatever it is, you can certainly try and repair your roof if you consider yourself handy. It could be a DIY project you would be proud to accomplish.

If you are planning to take on repairing your roof shingles for the first time, make sure you do all the research possible to ensure you are learning the appropriate methods and managing the project effectively. It is essential to know precisely how to repair your shingle roof and have all the necessary tools and supplies. You don’t want to make mistakes as this can lead to more significant problems with your home in the long run. Removing and repairing shingles is not an easy undertaking, so the appropriate tools will ensure you properly take out the shingles and nails before replacing them.

It is a dangerous job, so be careful. Look for sources providing guides to make the task as simple and efficient for yourself as possible. An added tip: Do not do it alone. Get yourself a DIY partner to keep the ladder steady or help with heavy supplies.

Here are some tools and supplies you’ll need.

A Ladder


This is necessary to get up onto the roof. Ensure you set the ladder up properly to not have it fall while you’re still up on the roof.

Protective Gear

You can never be too careful when working on your roof. Invest in a safety kit, including a safety harness or rope to strap yourself into.

Asphalt Shingles

Asphalt shingles are a more popular option. They can be purchased at a reasonable cost, they last longer, and they look great. However, other types of shingles are available as well, differing not only in material but also in aesthetic. For example, some shingles are heavier in weight, laminated or matte, shingles containing a rubber material, and so on.

If you are uncertain which ones you should purchase, speak to roofing professionals or the shingle suppliers for recommendations.

Crowbar or Pry Bar

These tools are used to remove sealant strips around the shingles. Use a crowbar to easily loosen and remove nails as well.

Roofing Nails

If you’re unsure of the type of nails you need to pair with the shingles, refer to a roofing guide.

Roofing Hammer

If a hammer doesn’t work as well as you want it to, get a hardier power tool to secure the shingles.

Ice and Water Protector

You want to make sure your replaced shingles stay in good condition, and leaks don’t recur. Apply an ice and water protector under your shingled roof to increase your roof’s resistance and prevent damage from strong weather conditions.


Sealant is used around any open space between shingles to prevent water from seeping through and, ultimately, into the house. It is also applied around roof vents and any other areas on the roof to fill gaps and provide further resistance against harsh weather and curious animals.


You want to purchase a protector that you can put over your roof in the event of rain. Shingles cannot be laid out if the roof is wet, so you want to take care to make sure the roof is covered well when you are not working.

6 Steps On How To Fix A Hole In The Roof

A hole in the roof invites disaster–from water damage on drywall and flooring to animal infestation. Temporary patch jobs are only effective until the rain starts. Repairing a roof should be a top priority for any homeowner. Handyman types who are comfortable on a roof can use basic carpentry skills to make this home repair without hiring a roofing contractor. Top Glaze has the best range of services if you’re looking for Melbourne roof repairs.

Step 1

Wear safety goggles and rubber-sole work shoes. Use an extension ladder with the third rung against the eave to access the roof. Carry tools in a tool belt.

Step 2

Take up the shingles over the hole. Slip a pry bar under the shingles above the affected area to pull out the nails holding the damaged shingles. Use hammer claws to help remove all nails from the shingles over the hole.

Step 3

Prepare the plywood or sheathing around the hole. If the hole is a cutout for a vent, the wood may be ready for repair. A hole from tree damage will be oddly shaped and splintered. Use a reciprocating saw to cut a square or rectangle shape around the hole and remove all splintered wood. Cut the plywood in half between the rafters if the hole is big enough.

Step 4

Patch the wood with plywood of the same thickness. Install a 2-by-4 brace under a small hole that extends three times the width of the opening. Hold it against the inside of the plywood by pulling it up through the hole while driving deck screws through the roof and into the brace. Use a jigsaw to cut a rounded shape from the plywood to the exact size of the hole. For large patches, nail 2-by-4 braces inside the existing rafters with 10-penny nails. Replace a plywood section with new plywood cut to fit the exact size. Nail the plywood sheet section to the braces with 8-penny nails. Cover the wood borders and bracing screws on top of any roof patch with roofing tar.

Step 5

Lay roofing felt or tar paper over the missing shingles. Slip the top of the paper in under the flaps of the shingles above the repair. Lay the upper sheet of tar paper 2 inches over the lower if two sheets are needed to cover the section. Nail tar paper on with roofing nails over every 18 inches of the perimeter and along with any overlapping sheets.

Step 6

Lay new shingles over the repair section. Remove the adhesive cover strip and lay the bottom row of shingles first. Use three roofing nails across the horizontal centre line to secure each shingle. Cover the lower row with the flaps from the next row up. Tuck the straight edges of the uppermost row under the remaining shingles and nail them under the flaps—Dab roofing tar over each fresh nail for added water protection.

Common Causes Of Hole In The Roof

As a homeowner having a perfect roof over your head can be the ultimate source of joy. The reverse is true, and the most stressful part of roofing may not be installation but maintenance. There are numerous roofing problems that a property owner can face ranging from a clogged gutter, missing shingles or improper installation. However, there is something most homeowners dread: a leaking roof. Water is a critical substance when confined to its areas of use, but when it intrudes on some sections of our lives, such as the roof, the effects are devastating.

The leaking roof has damaging complications that require quick identification and repair to be averted. Therefore, as part of routine maintenance practices, signs of leaks like musty smell within rooms or water stains on the ceiling must be checked regularly. In this piece, we are reviewing some of the causes of roof leaks commonly encountered.

Holes in the roof are some of the worst kinds of damage that your house can experience; it will lead to roof leaks plus associated damages. Here are some of the reasons roofs develop holes:

Storm Damage

heavy rain

There are many ways in which a storm can damage your roof, and some of them may end up leaving holes in your roof. For example, a storm can rip a section off the roof, rip off roof flashing or even rip off a few roof shingles. It’s also possible for big and powerful hailstones to drive holes through the roof, especially if the roof is aging and weak.

Nail Damage

There are different ways in which nail issues can create holes in the roof. For example, poor workmanship during roofing repairs (typically DIY repairs) may create holes if you accidentally drive nails in the wrong places. It’s also possible for old and rusty nails to have spaces around them due to the effect of corrosion.

Tree Damage

If you have trees around your house, you need to ensure that they are strong and not likely to fall anytime soon. This calls for removing weak trees (such as the diseased ones or the storm-damaged ones) and trims damaged or weak tree limbs. Otherwise, they may fall on the roof and cause serious damage, including holes in the roof.

Roof Installations

Roof installations such as communication gear (think satellite dishes or television antenna) and rooftop HVAC (heating, ventilation and air conditioning) can also create holes in the roof. This may happen due to poor installation, malfunction or damage. For example, poor removal of an old satellite dish can easily leave a hole on the roof.

Penetrations and Projections

Roof penetrations and projections are some of the most common causes of roof leaks. Penetrations such as chimneys, skylights, and vents should be properly constructed and maintained if they are to remain structurally sound. For example, the flashing and seals around the projections and penetrations need to be properly installed so that they don’t open up at the slightest threat, for example, during a storm.

Wear And Tear

Lastly, an accumulation of small issues from regular wear and tear can also end up causing holes in the roof. For example, water damage can cause sections of the roof to corrode or rust, which may cause holes in the roof in the long run.

How to Fix the Damaged Area?

The first step to knowing where you should patch your roof is finding where the damage is. You may know there’s a problem because your walls or ceiling are wet or because there’s a leak, but you may not know where the source of the leak is right away. Therefore, we have to narrow down where the damaged area may be. Looking for a roof replacement? Check out Top Glaze for a wide range of roof services. 

Begin by going to your attic and looking for areas of moisture, such as a leak or wet stains. From the outside, you can also try to spot missing or damaged shingles, as well as any penetrations in your roof, including the chimney, vents, or anything else that goes through your roof. If you can’t find the source of your leak in your attic, run water from your hose onto different sections of your roof. Have another helper watch out for visible drips from the inside of your house to confirm whether the area you are watering is the damaged part of your roof.

Dangers of a Hole in Your Roof

It’s a bad idea to ignore even the tiniest hole in your roof because that can lead to:

Roof material damage. Even a small amount of moisture penetration can damage the roofing materials and, left untreated, will only end up getting worse (meaning more expensive – possibly lots more expensive — to repair).

Health hazard. Humidity that gets into your house via a hole in the roof will eventually lead to mould and mildew. These are hazardous to the health, especially for someone who suffers from asthma or other breathing difficulties, has a compromised immune system, or is an infant or elderly.

Critter access. Another danger is that a hole in your roof “invites” all kinds of unwanted animal life inside. Think squirrels, mice, or raccoons.
