When replacing your roof, there are several problem spots that you should know about. The information shared herein discusses the most common areas. Of course, there are some that are unforeseen but most problem spots are common from one roof to another.
The areas on your roof that are most prone to leaks are the penetrations where your plumbing vents, exhausts, chimney, skylights, etc. are installed. In addition, your valleys and flashings are also common problem spots. These areas are often ignored by roofing companies because it takes time and money to do it right. Some companies underbid the replacement of your roof and therefore have to make up their profits by cutting corners.
I have seen so many roofs where corners were cut and if the roofer would have invested around $400 more, it would have meant the difference in a good roof installation versus a bad one. If you need a new roof, please, please, please do not assume that all roofing companies are created equal or that it’s simply taking off shingles and installing new ones. In addition, look for the following items to be discussed when you initially meet with the contractors that you’re considering.
- ROOF BRAND: When buying a new air conditioner, you can choose a dependable brand or the less expensive “off-brand”. It’s the same with shingles. Some companies get volume discounts by dealing with specific manufacturers. Nevertheless, do not let the roofer guide your decision to use an “off-brand”. Stick with established manufacturers like CertainTeed and GAF.
- PLUMBING VENTS: Why install a 25- year or 30-year shingle and then install a 5-year auto-caulk? Lead Boot Jacks do cost a little more, but they don’t become brittle and crack after 5 or 7 years. I see this shortcut most often.
- VALLEYS: I am always surprised when I tear off a roof and find nothing protecting the valleys. In some cases, it’s just felt there. Some companies will take it a step further and install a sheet metal, but as your house shifts, there will be tension around the nail penetrations and is still likely to leak with ice damns. Installing an ice & water shield in the valleys and around the penetrations will help avoid this. Ice & water is a little more expensive than sheet metal, but it performs better under these circumstances. purchase web domain.
- CHIMNEY: Your insurance company will not always include re-flashing your chimneys, but even if they do not, it should be discussed and included when applicable. Have your roofer inspect the chimney cap as well. If you have a brick chimney, have it inspected thoroughly. In some cases, the mortar between your brick is cracking and allowing water to penetrate.
- SKYLIGHTS: Much like chimneys, the flashing is often the problem. Installing ice & water under the flashing is also recommended…..and of course, make sure there are not cracks in the dome. If you’re going through hail, we can help!
