Common signs of underlayment deterioration include interior water stains on ceilings or walls, granules collecting in your gutters from shingle wear, or a spongy feel when walking on the roof. San Marcos' sun and occasional temperature swings can accelerate this wear. We recommend a professional roof inspection, which we provide, to assess the underlayment's condition without causing further damage.

It depends on the extent and cause of the cracking. For isolated cracks due to weathering, a targeted roof repair is often a cost-effective solution. However, widespread cracking often indicates the membrane has reached the end of its service life, and a roof replacement or reroofing is the more reliable, long-term fix for your San Marcos home. Our inspection will determine the best course of action to prevent leaks.

Reroofing, or adding a new layer over existing shingles, can be faster and less expensive if your current roof structure and underlayment are sound. However, a complete tear-off and new roof installation is recommended if there is underlying damage, such as deteriorated underlayment or decking—issues we frequently find in older San Marcos homes. This method allows for a full inspection and ensures a solid foundation for your new roof.
