Do flat roofs always leak?

Flat roofs have a bad reputation for leaking. The reason for this is their design. Technically flat roofs aren’t completely flat. They have a low slope to them so they can shed water, but that low slope doesn’t always shed water well. Sometimes water pools on the roof, and this will eventually cause leaks. That’s when flat roof repair becomes necessary. While flat roofs are a little more prone to leaks, they don’t always develop them or develop them about as often as other roof types. In many cases, ponding and leaks are due to poor installation in the first place. Of course, leaks can also be caused by severe damage like hail, but those circumstances are hard to prevent. When you do have leaks or other damage on your flat roof and need flat roof repair in Arlington, TX, you can always rely on the professionals at Frazier Roofing & Guttering Co., Inc. for exceptional service.

Flat roof repair or replacement

No matter what kind of roof you have, whether flat or steep-sloped, age plays a big role when determining whether it’s time to replace your roof, or if you can just get away with repairing it. Depending on the roofing material, flat roofs tend to have a lifespan of anywhere between 20 to 30 years, and as roofs age, the more wear they’ll receive, and one of the best ways to determine if it’s time to replace the roof is to have a reputable roofer like Frazier Roofing & Guttering Co., Inc. inspect the roof. 

A roof inspection will identify significant damage like cracks or punctures where leaks are more likely to develop. An inspection will check seams and areas where ponding occurs. If there are multiple problems, especially leaks, a replacement might be the best option. If the damage is minimal, a flat roof repair may be all that is necessary. Another option over replacement is an application of a roof coating, which can preserve the roof for several years.

What is the best material for a flat roof?

If you need to replace your flat roof, you have several options for them. What’s best for your building will depend on your particular situation. One of the leading options for flat roofing is PVC. It’s low maintenance and highly resistant to impact damage. It’s also less likely to crack than other roofs. Similarly, TPO is another good choice. These roofs resist tears and punctures and are as energy-efficient as PVC. These roofs’ seams are heat welded together in order to prevent leaks. Among the most budget-friendly roofs are modified bitumen, although they are subject to cracking, which will require flat roof repair.

How often should a flat roof be recoated?

One form of flat roof repair is adding a roof coating, which will create a seamless barrier over the roof that will help prevent leaks and increase the roof’s lifespan. Coatings will wear with age, so the roof should be recoated about every five years to continue protection.

How do you repair a flat roof?

Because the materials vary on flat roofs, flat roof repair will vary. For small cracks or holes, however, most flat roofs can be repaired with patches, and often you can find roof repair kits with the right materials to make a repair. You will have to make sure the patches match your roofing material. EPDM patches go with EPDM, for instance, while TPO goes with TPO. Some materials like modified bitumen will need to be heated with a blow torch for the patch to stick, while most just require roofing cement to be patched.

How do you fix a crack in a flat roof?

Depending on the type of material you have, most cracks on flat roofs can be repaired with patches. Repairs are fairly simple. You just have to make sure you use the same material for the patch as the roofing material you have on your roof. A double patch will provide extra water protection.

  • Cut away the damaged area with a utility knife. 
  • Apply roofing cement over the cut-away space.
  • Cut out a patch that is slightly larger than the damaged space and press it over the cement (some materials like modified bitumen need to be heat applied).
  • Apply more roofing cement over the first patch.
  • Cut out a slightly larger patch to place over the first patch for added protection.

Flat roof repair in wet weather

Like other roofs, flat roofs can be vulnerable to damage and leaks in severe weather. If your roof is damaged in high winds, you should wait until the winds die down before making the repair. But, if you need to make an emergency repair—to stop a leak, for instance—a flat roof repair can be made in wet weather. Have a roofing professional place a tarp over any section of the roof in which the roofing paper is missing or detached to prevent leaks until the rain lets up.

Flat roof repair residential

Although you’ll find most flat roofs on commercial buildings, some homes have them too. Flat roof repair on homes is similar to that on a commercial building, although the repair may take less time depending on the home’s size.
