Flat roof repair solutions for asphalt roof repair
Fix a leak in a flat asphalt roof
If you need to repair a leak on an asphalt roof, the first thing you should do is scratch and remove the layer of gravel from the area surrounding the leak.
Next, apply a new asphalt roof tar to the entire area surrounding the leak. Before the tar hardens, replace the gravel you removed with new gravel.
Remove a blister on an asphalt roll roof
Your asphalt roof shingles can get blisters for two main reasons: moisture is trapped in the shingle (typically during the manufacturing process) or your roof is poorly ventilated. If your asphalt flat roof has a blister, it is not necessarily something that needs to be repaired right away. However, like all blisters, there comes a time when they will pop. When blisters pop on roofs, granules will become dislodged thus leaving the asphalt unprotected from the UV rays of the sun. Once exposed, that area of the roof will continue to lose granules. With time and natural weathering, these popped blister areas can lead to leaks and roof damage.
So, to get rid of a blister and avoid problems in the long term—first, release the moisture by cutting open the roof with a utility knife through the middle of the blister and let it dry. Next, fill the blister with roofing cement using a caulking gun.
Afterward, you should nail a row of roofing nails on the sides of the blister and apply some extra cement to the nail heads.
To cover the blister, use a patch of asphalt roll roof slightly larger than the damaged area, and nail it to the original one over the repair. Finally, seal the patch and the nail heads with roofing cement.
Unblock the flat asphalt roof outlets
One of the most helpful tips for flat roof repair is a preventative one—making sure the roof outlets don’t become clogged.
When it comes to flat asphalt roofs, accumulated leaves and other debris such as toys, e.g., baseballs and nerf darts, can easily find their way into your roof outlets. The roof outlets easily become clogged, and this will cause water to pool on the flat roof, which makes the roof vulnerable to leaks.
To avoid clogged roof outlets, there are a few steps you can take: clean your drains once a month and keep your roof deck clean.
Taking on roof repair by yourself can seem like a daunting task, especially if you don’t have all the tools and supplies you need to begin with. That being said, sometimes it can make more sense financially to hire a local roofing pro.
