Flat roofs are cost-effective and straightforward to install and maintain, which is why many homeowners prefer them. These roofs are also available in many styles and fit most architectural designs. However, they are prone to moisture leakages.

Unlike sloping roofs, these cannot shed water, making it one top disadvantage. However, there is a remedy to any leaks that could occur. Homeowners and installers use bitumen membranes, sealants, liquid rubber, or repair the roof to stop the leaks.

This article has detailed information on these tips, but before we get into them, let’s first look at what to do if your roof leaks.

You Can Repair Or Replace A Leaking Flat Roof

Choosing to repair or replace the entire roof due to leaks depends on many factors. For example, if the roof is old, you should install new waterproofing. An old roof will cost you money and time to keep repairing but buying a new roof will deal with all the problems.

However, repairing the roof will be ideal if the roof is new and the leaking parts require minor repairs. Skilled homeowners can DIY on the small patches using sealants and other products like bitumen membranes to increase waterproofing.

How To Know If The Roof Requires Waterproofing

Rain is not the only way to know that your flat roof is leaking. Check out the other signs.

  • Brown patches on the roof

The underlayment cannot hold any moisture due to condensation or rainfall when it wears out. Instead, the water seeps through the roof slowly. Later, you’ll notice brown patches on the ceiling or some dampness. A professional will help to trace the exact leaking part.

  • Exterior damage on the shingles

If you notice discoloration on a particular part of the roof, the chances are high that water is penetrating and needs repairs. Another sign can be peeling paint and wet sports on a specific roof part.

  • Drips when it rains

A dripping ceiling when it rains is a perfect sign of leaks. However, the leaking could be due to plumbing and roof construction defects, but you need to improve the waterproofing.

Homeowners should schedule inspections to detect any problems with the roofs before they get worse. Water leads to significant damages like rotting and molds which can spread to the entire home. Moisture can also weaken wood roofs and shingles, which are expensive to replace.

Once you notice signs of leakage on the flat roof, you should think of stopping it. Find the best ways to waterproof the flat roof. Check out for some that we found.

  • Ask for professional help

An experienced roofer will identify the leaking parts and the causes of the leaks. Dealing with the cause of the leak, which could be damaged shingles, will help your waterproofing last.

The roof expert will also advise whether to repair the waterproofing or replace the entire roof. Although most homeowners insist on trying DIYs on their home projects, the roof is sensitive for DIYs.

  • Use bitumen membranes

Many roofers use reinforced bitumen membranes to restore their flat roof’s waterproofs. The process seems simple for a DIY, but you need professional guidance.
The roofer starts by installing two or three layers of material and bonding it with bitumen. They finish up by applying polyester to the material to add a waterproof membrane.

There are different methods of installing a bitumen membrane. Installers apply methods like pouring and rolling the substance, torching, or using the cold adhesive form. However, the application method does not matter, but it should be well done.

  • Use the repairing kit

Roof manufacturers make repair kits for specific roofs. Some sell the kits alone, while others pack them with the roof. These kits have patches for repairing waterproofing damages and are ideal for DIYs.

Although the patch stickers are a quick fix for a leaking roof, they work perfectly as the homeowner finds a permanent solution. You, however, need first to know the areas that need repairs.

  • Sealant

Sealants are an excellent way to add waterproof to your flat roofs. This method is ideal for small cracks that need a quick fix, but some homeowners and roofing experts use it for the entire roof.

A roofing sealant is a quick and easy solution that is simple and easy to use, and you don’t require an expert. Although it is a quick fix, the sealant lasts a long time. It is ideal as the homeowner prepares to fix the waterproofing permanently.

  • Liquid rubber

Liquid rubber can waterproof small and large areas and does not require expertise. This is a perfect way to waterproof new roofs with minor damages like cracks. However, liquid rubber is not a quick fix like the sealant and patches.

The waterproofing material is also ideal for new roofs, and roofers use it as the first waterproof. The first step to using liquid rubber is priming the surface first. Then, the rubber covers the roof with a thick coat that is waterproof and lasts a long time.

Practice Safety

If you notice leaking when it is raining and want to inspect to see the cause, wait for the rain to stop. Going up the flat roof with wet shingles can lead to slides and falls. Instead, use a firm ladder and well-treaded shoes for more safety.

Also, avoid putting ladders against gutters as they cause damage and slide. You should get two people to hold the ladder firmly to ensure you are safe as you climb the roof.

Final Words

Keep an eye on your flat roof’s waterproof and know when to repair or replace it. Homeowners are spoiled for choice with ways to waterproof their roofs. Ensure you choose the best method to avoid spending more money and time the next time it rains.
