All roofing systems will show signs of issues, no matter how sophisticated, or durable they are. One of the main problems that affect modified bitumen and ethylene propylene diene monomer (EPDM) roofs is roof shrinking. In today’s post, the top source of roof inspection and repairs, Evans Roofing and Gutters Inc., shares the causes of roof shrinking.
What Is Roof Shrinkage?
Roof shrinkage pertains to the reduction of your roofing membrane’s size that protects it from the elements. This is a serious concern that affects your roof’s protective capabilities against severe weather elements and temperature changes that can accelerate your roofing system’s deterioration.
Your roof repair expert would tell you that it can cause your roof to shrink over time, which leads to serious issues like cracks, punctures, and torn roofing membranes that will leave your home open to water infiltration. You should call your roof repair expert for immediate assistance if you see these signs of damage. After all, these are problems that can grow worse if they’re left unattended.
What Causes Roof Shrinking?
The top cause of roof shrinking is slipshod roofing installation. If you’re using a modified bitumen roofing system, your contractor should apply the material first, and let it set before applying the end laps. If you’re using an EPDM roof, the ballast must be applied immediately to prevent heat from affecting the roofing membrane. If these steps aren’t followed, you can expect your roof to shrink quicker, and your roof’s lifespan to be shortened as well. This can be repaired by cutting off the affected parts and securing the field sheet with a RUSS strip, and reapply a new flashing for the safety of your roof.
