It's important to replace your old roof before it gets so worn out that shingles fall off or the roof starts leaking. When your roofer examines the condition of the shingles and deck, they may recommend a total replacement. Here's why a roof replacement is often a better choice than adding a new layer of roofing and the steps involved.
Why A Roof Replacement Is Needed
Building codes usually limit roofing to two layers. If your home has two layers of roofing material already, then a replacement is the only option. However, even if your roof has a single layer of shingles, you may want to replace them rather than cover them up with new shingles. Replacing the roof gives the contractor the chance to replace all worn parts that are hidden from view such as the leak barrier and roof deck. This gives extra protection against leaks. Plus, nailing new shingles directly to the deck could mean a roof that lasts longer and performs better than nailing shingles over a layer of old shingles that have various amounts of granule loss, curling, and other damage.
The Steps Involved In A Roof Replacement
Replacing a roof involves tearing off old roofing materials and hauling them away. The roofer also has the chance to make changes to the roof to address any problems you may have such as poor attic ventilation. If the deck is rotted, it may need to be replaced before shingles are put on. Then, the roof is built from the deck up so your roof has new materials to fight the weather for years to come. A roof replacement takes longer than adding a new layer of roofing, but the work can usually be completed in just a few days from tear off to clean up. Don't forget that getting a new roof is a noisy undertaking, so you might want to stay out of the house while the crew is working.
You have the chance to try a different type of roofing material when you get a roof replacement. You might want tile or metal for an entirely new look or for a longer life than asphalt. You could also upgrade to more durable asphalt shingles that last much longer than traditional, builder's grade shingles.
You can usually have a roof put on during any season of the year as long as weather conditions permit, but it may be difficult to book a time you like during the busy summer season. Rather than wait until your roof develops problems, anticipate when your roof is nearing the end of its life so you can have it replaced at your convenience and before it starts leaking.
