There are many different practices and procedures that roofers may use when putting a new roof on a home. As a homeowner, you may not know the difference between the best practices and those that are likely to lead to less-than-ideal results. When speaking with roofing companies regarding your new roof, you'll want to avoid those that recommend these practices – or at least request that they use a different method for your roof.
There are two main ways to "put a new roof on a home." The first, referred to as a "tear off and replace" involves ripping off the old shingles and drip edge and putting new ones on. The other method is called "recovering" and involves putting a new layer of shingles and drip edge over the existing one. Recovering is cheaper and easier, but it is not the best choice for most homeowners. It causes shingles to age more quickly, as mold and fungi can grow between the two layers of shingles where moisture becomes trapped.
If a roofer suggests recovering your roof rather than doing a tear off and replace, politely decline and insist on the tear off. You won't save any money in the long run with a recover, since you have to replace the roof sooner.
Skipping the ice shield.
Ice shield is a special waterproof material that is typically placed along the first few feet of the roof's edge. If ice backs up in your gutters, it prevents it from causing leaks inside or near your interior walls. If you live in a warmer area, some roofing contractors may skip applying ice shield to the roof. However, this is not a wise practice, since ice shield serves a secondary purpose – it offers water protection should your gutters become clogged with leaves and debris. Always say "yes" to ice shield, even if temperatures never drop below freezing in your area.
Using staples rather than nails.
Some roofing companies attach shingles with staples rather than nails in order to save time. If you encounter a company that wants to use this practice, politely request that they use nails on your roof instead. Nails are tougher and longer, so there is less of a chance of your shingles being pulled off in a heavy wind when you use them.
It's always a good idea to ask a roofing company about their method before you hire them to replace your roof. If they say they will use one of the practices above, you can either get them to agree to a different practice, or hire a different roofing company.Share
