A good roof doesn't only have a sturdy asphalt shingle layer that withstands hailstones and delivers water runoff to your gutters. Excellent roofs are a comprehensive system with each component supporting each other. For example, a six-inch gutter system propping up a high-slope roof is efficient because the big gutters can handle roof runoff.
For most homes, a roof with excellent attic ventilation and insulation brings many benefits. First, it lowers cooling and heating costs for your home because it dissipates the heat and takes in fresh air from the outside. Second, insulation reduces the descent of hot and cold air into the interiors and improves your home's energy efficiency.
Unfortunately, some builders may have built a lacking attic ventilation and insulation system for your property. It is challenging to head up to your attic and inspect its condition. However, if you see the following signs, it might be time to have your attic insulation improved.
Insulation helps the attic and roof materials have equal and stable temperatures. Common causes of insulation damage are wet insulation and signs of mold growth. If it's tattered and worn, it will require replacement. Have a roofing professional check the insulation and recommend ways to restore it. They will need to improve your insulation before building your attic ventilation.
High-quality roofing materials will suffer from poor installation. Asphalt shingles that endure heat beyond their limits will have blisters and crack. Hot air from the attic will heat the sheathing and shingles. If you see shingles buckling, racking, and warping, you have a roof surface that's too high because of problematic attic ventilation. Good ventilation and insulation ensure the asphalt shingles have stable temperatures that help them last long and have better endurance.
Expert roofers are correct in implying a dry roof and attic are long-lasting and strong. Attic moisture indicates water damage to the rafters and sheathing. When damaged, these components will require a tear-off roof replacement to replace the underlayment, sheathing, and rafters due to water damage, mold growth, and eventual wood rot. Good ventilation reduces attic humidity and won't grow molds.
Nails and fasteners on the OSB or sheathing shouldn't rust. Sheathing that has suffered water damage indicates a problem with your sheathing and attic ventilation. If you discover this damage within halfway of your roof's lifespan, save up for a tear-off roof replacement later. This process removes the entire system, letting roofers inspect the condition of your sheathing, rafters, underlayment, and other wooden components.
Sagging indicates severe structural damage. It is the result of continuous leaks that have led to severe water damage. Over time, soaked rafters and sheathing will become mold colonies and weaken due to wood rot. Don't take sagging lightly and call a roofer for immediate fixes.
