Metal roofs were once a novelty, designed for barns and other commercial and industrial facilities. Today, they are widely used and are a great alternative to asphalt shingles covering houses.
What should I look for when choosing a metal roof?
Metal roofs are no longer just “metallic” like they use to be. You can purchase metal shingles that mimic the look of asphalt shingles and have no disadvantages. Metal is more readily available as a roofing material than in the past, and its market share is growing at a rate of about 3% per year. It is therefore not surprising that 15% of all roofs installed today use metal as their primary roofing material.
However, not all metal roofs are manufacture in the same way. Therefore, it is important to consider several factors before deciding on a metal roof replacement. Here are some considerations to keep in mind when choosing this type of material.
1. Premium and certification
There is a quality certification program develop by the Metal Building Institute. The purpose of this program is to certify manufacturers and products that meet certain strict standards for manufacturing processes and materials for metal roofing products. Look for contractors that offer products with this certification.
2. Reliable warranty
It is not enough to offer a warranty on a new roof. You don’t want to have to pay to have your roof repaired because of a manufacturing defect or a raw material problem. Be sure to obtain a product (and raw material) warranty and a manufacturing warranty.
Poor roof ventilation damages asphalt roofs and shortens their service life. Metal roofs are much more durable than asphalt roofs, but overheating in the attic can still cause problems. Without proper ventilation, ice buildup can form and water can seep through to the underside of the metal shingles. It can also lead to mold and roof wood rot. To maximize the performance of the metal roof, the contractor will ensure that the roof is install to provide proper ventilation.
4. Open Valleys
Many metal roofs have hidden or closed holes that allow water to quickly drain off the roof. However, these gutters can accumulate debris when fallen leaves, conifers, dead branches, and other debris fall onto the roof. Open troughs are prefer because they are “self-cleaning”. There are no clogged slots that can cause water leakage.
5. Resin-Based Finish
Asphalt shingles are easily staine and scratched. This is why many people choose to replace it with metal shingles. To enjoy a perfect metal roof more, choose a longer-lasting resin-coated metal shingle; Kynar 500® and Hylar 5000® PVDF resin coatings are the best choices in terms of scratch and stain resistance.
