The signs and causes of roof failure and what you can do to prevent it.
How often do you think about your roof? It’s always overhead, keeping your home or commercial building safe from the weather, but it’s also taking a lot of abuse as you go about your daily life. Damage that results from the following three problems builds up over time and can lead to all-out roof failure if not addressed.
Blistering
Roof “blisters” generally start as leaks. Water gets into the roof through damaged shingles, cracks, or holes in the roof membrane, and when the heat of the sun hits the roof, the moisture expands. A continual cycle of this puts a great deal of pressure on the roof piles, causing them to push apart and create a raised bubble that can clearly be seen. Insulation beneath the roof that stays wet perpetuates the problem by keeping moisture in constant contact with the piles.
Splitting
Poor installation or improper pairing of materials can cause your roof to split. Connecting materials that expand and contract at different rates strains whichever one has less give, and the only way it can deal with the force is to crack. Expansion joints that aren’t put in correctly experience similar stress and have a tendency to give out at the seams. Splitting may also be a consequence of age as years of wind, rain, sun, and snow catch up with your roof and the supports become less able to handle the constant barrage.
Lack of Maintenance
A roof isn’t something you can forget about after it gets installed. Constant exposure to the elements wears down all kinds of materials, some faster than others. If you’re not having your roof maintained on a regular basis, you could be missing small signs of trouble that can add up to big problems later on.
In some cases, maintenance in and of itself can cause the roof to degrade. Mistakes or poor workmanship can leave behind holes that allow moisture to get in. If you want your roof to last, you have to choose a roofer you can trust.
