Repairing Heat-Damaged Roofing and Preventing Leaks

Fact: San Antonio summer roof temperatures exceed 160°F, accelerating shingle wear and cracking.

The South Texas sun beats down all season, drying and cracking shingles—creating pathways for leaks during monsoons. Proper repair and preventative steps keep your roof watertight.

 

1. Inspect Shingles for Heat Cracks

Look for curling edges, cracked granules, or faded spots. Cracked shingles let rain through, leading to roof leaks and interior water damage cleanup. Replace any compromised pieces promptly.

 

2.  Re-Caulk Flashing and Penetrations

Around chimneys, vents, and skylights, old caulk dries out under the sun. Remove failed sealant and apply a high-temperature silicone. Solid flashing prevents water from following rafters into drywall, avoiding later water extraction & removal.

 

3. Install Reflective Coatings

A reflective roof coating reduces surface heat by up to 30%. Cooler roofs last longer, and lower heat reduces warping of underlayment that contributes to structural restoration work if leaks develop.

 

4. Clean and Seal Gutters

Heat-dried leaves and debris can trap rainwater, pushing it under shingles. Clean gutters twice a year and seal seams with waterproof tape. Properly flowing gutters cut down on storm and wind damage cleanup after summer showers.

 

5. Improve Attic Ventilation

Hot attic air radiates back into shingles, accelerating damage. Ridge vents and soffit vents exchange attic air efficiently. Cooler attics extend shingle life and prevent the sudden leaks that demand emergency water restoration.

 

6. Use Impact-Resistant Shingles

If replacing, choose Class 4 shingles rated for hail and heat. They withstand temperature swings without cracking, reducing future burst pipe damage cleanup chances by stopping leaks at the roof before they soak interior pipes and wiring.

 

7. Schedule Professional Roof Tune-Ups

Have a roofer check your roof annually. They spot small problems—loose nails, minor flashing gaps—before they let rain in. Early repairs cost a fraction of full fire damage cleanup or major roof replacements.

We had quite a bit of damage from a tornado/storm back in May 2024. So we needed a lot of work.
We had used Dwyer Restoration when we lived in Rockport Tx. Which was from Hurricane Harvey in 2017.
He was our Angel.
All the work then and now here in San Marcos TX. The staff and workers have done an outstanding job.
We have another project in the works now.
He is a man of word and will always leave the customer satisfied with the project.
We will continue to use Dwyer Restoration.

Oh. My. Gosh. I have known about Dwyer for ages, but never in a million years did I think I would need to call a restoration company…until the day came. They were quick, professional, and EXTREMELY knowledgeable. I didn’t question for a second that they knew what they were doing, and they thoroughly answered every question I had along the way. Dwyer, I cannot thank you enough for your help during such a stressful time!

Dan and his entire crew were amazing. There were some hiccups along the way (had to change project managers part way through which was out of anyone’s hands). Our new project manager Edward was awesome. The one issue we had was with the subcontractor painting company. Dwyer built us beautiful new cabinets and to this day the paint job is what I would call “satisfactory.” In the end it was quite clear these painters were only going to do enough for a satisfactory job and that is where we left it because we didn’t want to have them come back for a 9th (literally) time. Dan Dwyer and Edward pushed hard to get them to fix things even going as far as to sit here and supervise while they worked. In the end the painters were just lazy and you can’t really fix that. The lesson here is absolutely use Dwyer Restoration. They are prompt, kind, fair, hardworking people and we would use them again in a heartbeat. Their internal survey got an 8/10 overall because of these painters but I do believe deserve a 5 star rating on here because they deserve your business and will not do you wrong. The second lesson is DO NOT use Carnival Painting if you actually want a quality paint job.

I recently had the pleasure of working with Dwyer Restoration to address significant water damage and mold issues in my home. From start to finish, the experience was exceptional, and I couldn't be more satisfied with their service.

From the moment I contacted them, the team at Dwyer Restoration was responsive and professional. They arrived promptly for the initial assessment, thoroughly inspected the damage, and provided a clear and detailed schedule to address the issues.

The remediation work was carried out efficiently and meticulously. Their team also took great care to protect the unaffected areas of my home. I was particularly impressed with their attention to detail and commitment to quality. My cabinets were needing to be rebuilt, all drywall at the kitchen peninsula was replaced, textured, painted and caulked better than it had been previously when the home was new.

I highly recommend their services. Their professionalism, expertise, and dedication to customer satisfaction make them the best choice for home remediation needs.

We hired Dwyer to do a full kitchen remodel after consulting with a number of local remodel and restoration companies. Their bid was comprehensive and detailed (almost a little overwhelming). They were quick to answer questions and turn the bid back around with adjustments.

The trade workers were competent and always polite. There were a few bumps as I would have expected with any major project. Dwyer responded to each concern in a timely and fair manner. In the end we were very happy with the result and would be willing to use them again.

Some details about the project:
* removed a load-bearing column and replaced with a LVL span. This required adjusting plumbing, electrical and HVAC around the area, as well as working with the city and a structural engineer for approval.
* replaced 4' fluorescent bulb lighting with recessed LEDs.
* custom cabinets (amazing work on this!) and new counters. This included converting the kitchen island into a peninsula.
* rebuild pantry with a slightly different footprint to better utilize space.

The majority of the work was done over about 60 days, with touch-ups and adjustments going on about a month longer.

My neighbor ran his car through my house in December 2019. The entire left side of my house was a huge hole and destroyed. Dwyer Restoration was recommended as the "disaster specialists". I am SO GLAD I hired them out of the 7 others I had come out to give me bids. They were the absolute BEST in the business to work with. I found them to be exceptional in 3 areas specifically:
1. Communication
2. Professionalism
3. Cleanliness
There will always be bumps along the way with ANY restoration/renovation. The key is, to work with people that DO THE RIGHT THING. Dwyer ALWAYS came through no matter what and did the right thing. They handled every detail of my renovation as if it was their house and what they would want done.
Dan Dwyer held my hand throughout the entire insurance process daily and we were able to get things agreed upon due to this.
Mark Brown was my project manager and did a phenomenal job with scheduling and being there every time I called. He was a pleasure to work with and made everything seem so seamless.
Guido Krumm was the German Carpenter that did most of the work on my house. He was also a pleasure to work with. I fell blessed to have had such a knowledgeable and trustworthy person doing the work on my house.
I will ONLY hire Dwyer Restoration in the future for all of my renovation needs. I HIGHLY recommend them for your next project or disaster.
