Typical Roof Issues and Solutions

Maintaining awareness of these typical problems will help to keep the water outdoors, where it belongs.

That roof above your head, the one that shields you from the weather and keeps you dry? It won’t survive forever, but it will withstand wind, sleet, snow, and storms for decades. The roof will deteriorate due to a number of possible problems, including old or broken shingles, worn-out flashing, blocked gutters, and more. It happens gradually: first, water seeps in via a loose shingle or worn flashing piece, then rot sets in and eventually water begins to destroy your home. Preventing these little issues from becoming larger, more costly ones is the best course of action. What you should know is as follows.

Typical Roof Issues 

Indications that your roof is leaky

It’s not necessary for a leak in your roof to appear as a torrent or even as a constant drip, drip, drip. You could have a little leak if you discover an unexpected damp spot or a stain on your ceiling that keeps getting bigger. Examine the space above the leak if you can get into your attic. Are there any portions of the sheathing or rafters that are discoloured or have moist insulation? While you inspect below, you might even want to have someone use a hose to saturate specific sections of the roof. After locating the leak, you must identify the related issue on the roof’s surface.

Note: Slate, metal, and tile roofs in particular can have extremely slick surfaces that might be dangerous when paired with a steep slope. The ideal person to fix them is a specialist in these specific roofing materials. Always think about hiring a professional for any roof repairs—they have the tools and the knowledge.

Typical Roof Repairs

Missing, ripped, or loose shingles

These items are necessary if you need to replace your shingles:

• Hammer for Ladder
• Level bar
• fresh shingles
• Nails for roofing
• Caulk gun
• Sealant for roofs

Choose a day that isn’t too hot or too cold because those temperatures cause shingles to become brittle or soft, respectively, and begin by breaking the seal between the shingles with the flat bar. Before the nail comes out, slide the bar up under the first nail and pound the bar with the hammer. Continue until the painful shingles disappear. Nail in the new shingles, starting with the lowest course. To insert the nails in the last course, you will need to raise the shingle above. Place a bead of roof sealant under the leading edge of every shingle that has been replaced, as well as the shingles that are directly above them.

Vent boots

There may be rips or breaks in the rubber boot that surrounds the plumbing vents. It could be able to replace simply the boot if the aluminium flashing isn’t leaking.

The boot you select for the flashing replacement must match the diameter of the vent pipe. (Flashing units with movable boots could be available.) Lift the base and boot off the pipe, pry up the exposed front edge of the old flashing with a flat bar and take out any nails. The new flashing unit should be generously coated with a bead of roof sealant before being put over the pipe and beneath the shingle course directly above it. Use nails with neoprene washers, or replace the nails, sealing any exposed heads.

Additional Roofing Problems

Other flashing sections on the roof, including the step flashing at the foot of a dormer or neighboring wall, or the counter flashing encircling the chimney, may also have leaks. Use roof sealant to patch any fractures in the counter flashing around your chimney and reattach any missing pieces.

There are two things you may do if you discover a leak in the step flashing around a skylight, a sidewall, or along a dormer. The first step is to repair the flashing, which requires removing the nearby shingles and siding and then doing it the other way around by installing new siding and flashing.

The second choice is to use a sparing amount of roof sealant to fix the broken flashing. The secret is to maintain the sealant’s surface as flat as possible since large lumps or beads of sealant can actually redirect water and obstruct effective drainage. If the nails used to hold the flashing are visible, sealant should be applied to their heads. Sometimes the repair serves just as a temporary fix until the flashing can be replaced along with the roof.

Ice dams

If you reside in a chilly climate, you could have come across leaks brought on by “ice dams.” A freeze-thaw cycle is brought on by warm air exiting the attic through the eaves at the edge of the roof. As the ice melts and condenses due to the warm air, water seeps through the shingles and into the home. Avoid attempting to cut away the ice as this will just cause harm to the shingles and not address the issue. A more long-term fix is sealing air leaks in your attic, adding extra insulation, and even hiring a contractor to install new shingles and a self-adhesive membrane along the edge of your roof. You can install a roof de-icing cable.

Gutters

Gutter maintenance is important since neglecting it can lead to roof issues as well. Gutter backflow is caused by a blocked downspout. Growing vegetation in the gutter can lead to water damage to the fascia and eventually rotted rafter tails. In addition, the overflow may pour out onto windows or siding, adding to the issues already associated with water.

Cleaning and inspecting the gutters at least once a year is the answer. To remove dead leaves and twigs, you’ll need a ladder once again, in addition to a small garden trowel and pail. Having a hose up there is also helpful for clearing smaller debris with a water stream.

You might need to make repairs if your gutters are older. Verify that the gutter is securely fastened to the fascia, and replace the hangers as needed. To repair leaky seams, use a caulk gun that has been equipped with a tube of roof sealant.

Moss

Patches of moss may form on the parts of your roof that receive no sunlight, if your house is even somewhat shadowed. Moss is a nuisance for the rest of us, but hobbits could believe it’s a wonderful thing. When it penetrates shingles, it breaks the seal and lets leaks in. It accelerates the deterioration of all kinds of roofing materials, especially asphalt and cedar shingles.

The roof may be cleared of moss in a few different methods. Should you be installing a new roof, using copper or zinc strips in between shingle courses will stop moss growth before it starts. If your old roof isn’t going anywhere, grab a ladder, some non-slip shoes, a long-handled scrub brush, and a hose—not a pressure washer—and head up onto the roof. Direct a powerful stream of water into the moss while standing above the mossy sections, and then use the brush to push the moss off solely by moving it downward. As often as necessary, repeat, taking care not to harm the shingles.

Commercial sprays that kill moss include Safer’s Moss and Algae Killer and Moss and Algae Cleaner. If you’re feeling very adventurous, you might also combine one-part water with one-part liquid laundry bleach, spray the mixture on the moss, and then use the hose to rinse it off after twenty minutes.
