We recently experienced some extreme weather here in Texas. We had snow flurries and very low temperatures followed by a rapid thaw as temps quickly increased. Let’s talk about how your valleys operate, how extreme weather affects them and why proper valley construction is so important.
What is a valley?
A valley is formed by two intersecting slopes of a roof. The valley channels rainwater from two intersecting roof surface areas off the roof. Valleys collect water by design, the valley channels rainwater off the roof. Valley areas are often also shaded by higher roof peak and sloped areas. Any part of the roof that is shaded can be as much as 20 degrees colder than an area that gets direct sunlight.
What is an ice dam?
An ice dam is a buildup of ice that forms and prevents melting ice (water) from draining off the roof. The water that backs up behind the dam can leak into a home and cause damage to walls, ceilings, insulation and other areas.
Snow, or ice, tend to accumulate in your roof valleys (from top to bottom). Near the top of the valleys, where its warmer, frozen areas begin to melt and runs down the valley. Hot air in your attic rises, so it’s always going to be warmer nearer the top of your valleys, and colder near the bottom of your valleys. All of this is a perfect recipe for an ice dam.
Ice melting may freeze again when it reaches the colder lower part of your valleys. This lower part of the roof sometimes becomes packed with even more frozen buildup, which impedes the watershed design of the valley, sometimes to the point of redirecting water under shingles, or breaching other waterproofing lines of defense.
Why Proper Valley Construction is so important!
For over a decade we have been installing ice & water barrier in all valley areas. The ice & water barrier is a self-adhesive waterproofing roof underlayment that acts as a shield against water and ice damage. It’s also made of modified bitumen (slip-resistant material), which provides a watertight seal around the shingles and around penetrations.
Even though we do not see ice buildup often, or even annually, installing this barrier on all of our projects bolsters protection against the elements in all seasons.
Quality means doing it right when no one is looking.

Honesty is the best way to describe them. After inspection I was told our roof is in good shape. Not many companies do this.

I had a great experience with Roofing Solutions DFW. We had wind damage to our siding, a problem we have had many times but the people we hired in the past did not repair it correctly.
Roofing Solutions came out and recommended the correct way to repair it and got started the next day. The crew was very professional and did great work!
Right after the repairs were completed, the storms came rolling in! I am happy to report my siding is intact and looks great!
I highly recommend Roofing Solutions DFW 👍

Roofing Solutions DFW have proven themselves to me several times, making them the first I call, if it's something they can do. The quality of their work is outstanding, their prices competitive, and they have been honest with their dealings. They've earned my repeat business.

We had a small job to replace a dryer vent on our roof along with minor shingle repair and Jerry and his took team took great care of us. They were quick to respond, professional, and had the best quotes from the few roofing companies I contacted. I will definitely hire this team for my next roofing project.

Roofing Solutions DFW recently worked on some chimney damage I had gotten from a nasty storm a month or two ago. The high winds had blown off some outer panelling that needed to be repaired and repainted. Jerry Esparza was a pleasure to talk to when I called them to get an estimate and he made me feel comfortable with his friendly tone and knowledge. Their bid came in as the most affordable one from the 3 that I got and they were able to perform the repairs in an afternoon, including repainting the entire chimney exterior. The crew was nice and left the work area clean and made it look like brand new. I highly recommend Roofing Solutions DFW and would use again!

I've known Jerry Esparza for about 15 years. We met when our daughters were competing against one another on the basketball court when they were young and realized that we went to the same church. I first enlisted Jerry's help with a roof inspection several years ago after having two other roofing companies, tell me that I needed a new roof. Jerry came out and spent a lot of time walking over my entire roof and taking pictures And then told me that my roof was in good shape and did not need to be replaced. I appreciated his honesty! obviously, he did not get the job… But saved me a ton of money by telling me the truth, When other roofers were trying to obviously take advantage. I appreciate someone with that much integrity and always keep them on my short call list for future jobs. Jerry recently came out and installed some gutter guards on my gutters and painted a roof stack for me. He did a wonderful job, showed up on time and had very competitive pricing. I will always use Jerry for all of my roofing needs and highly recommend him. Dennis R.~Lewisville.
