Question Answers

How can I tell if my roof's underlayment is deteriorating, and what does S&J’s do to fix it?

Common signs in San Bernardino include interior water stains, cracked or curled shingles, and granules in your gutters, often worsened by our intense sun. S&J’s starts with a detailed inspection to assess the underlayment damage. We then carefully remove the affected shingles, replace the deteriorated underlayment with a high-performance synthetic or felt underlayment suited to our climate, and re-install your roofing materials. This process restores your roof's primary water barrier and prevents further structural damage to your home.

What causes roof membranes on commercial buildings to crack, and how do you handle repairs?

In the San Bernardino area, roof membranes on flat commercial roofs often crack due to thermal expansion and contraction from our hot days and cooler nights, along with UV degradation. S&J’s handles these repairs by first locating all cracks and assessing the membrane's overall condition. For localized damage, we perform seamless patching and reinforcement with compatible materials. If the cracking is widespread, we may recommend a full membrane replacement using durable, reflective coatings to better withstand our local climate and extend the roof's lifespan.

As a general contractor, does S&J’s handle both the roofing and resulting interior damage from these local issues?

Yes, absolutely. As licensed general contractors serving San Bernardino, we provide a complete solution. If a failing underlayment or cracked membrane has led to water intrusion and interior damage like stained ceilings or damaged drywall, our team can coordinate and manage the entire repair process. This includes the roof repair itself, followed by any necessary interior restoration work. We handle all the details, ensuring a seamless, single-point-of-contact repair that gets your property back to full protection and appearance.
