5 Things to Consider When Replacing the Roof on Your Home
Advancements in the residential roofing market have made replacing a roof a once-in-a-lifetime event for many homeowners. Purchasing a new roof is one of the most important home improvements that occur and is typically a big investment in one of your most valuable assets. It’s important to understand these five factors before you replace your roof.
1. Roof Sheathing – It is important to replace any damaged or deteriorated sheathing before your new roof is installed. The best way to accomplish this is to tear off the old roof system and perform an inspection of the roof sheathing. The sheathing is typically wood planks (1×6, 1×8, etc.) or wood panels (OSB or Plywood). If roof leaks have occurred for an extended period of time, wood replacement is likely required. Some homes were designed with roof sheathing that is too thin to support the weight of roofing materials as well as snow and ice. It is important to have an estimator walk your roof or look in your attic space to determine the integrity of your roof sheathing.
2. Flashings – Since most shingle manufacturers offer warranties up to 50 years, it’s important that all of the accessories on your roof will last 50 years as well. Flashings are the most important accessory of all. Flashings are required at any roof penetration such as vertical walls, chimneys, skylights, plumbing vents, and roof edges. Make sure you remove the old flashings and replace them with new ones if you want a roof system that will perform for years to come. It is much more expensive to repair or replace flashings at a later date.
