Sometimes, Jacksonville roofing contractors who have been in the business a long time go on using practices most companies have stopped. You should always expect the latest tools and techniques for your Jacksonville roofing project.
Here’s what to watch out for to get a true “full roof replacement in Jacksonville.”
1. Don’t Go Over The Old Shingles With New Ones
In the past it was very common for new roofing shingles to be layered on top of old ones. The main purpose of this was to avoid the time spent removing and disposing of older shingles.
Unfortunately, layering roof shingles can contribute to a whole host of problems. It doesn’t, as some may believe, make a roof more resistant to harsh Florida weather. In fact, the top layer of shingles becomes much more likely to blow away in storm-force winds.
“Roofing over” is a rare practice these days, but it should still be avoided. In addition to extra wear and tear on your shingles, it makes it much harder to fix any roof leaks that develop later.
2. Always Strip The Roof Decking Bare
The roof decking is the layer of a roof system that sits between the house’s structural parts (like the trusses and joists) and weatherproofing layers on the surface – mainly shingles and coatings.
You almost never get the chance to see the roof decking up close without its shingles, so be sure your contractor takes the chance to perform a full inspection. Roof decking is usually made from plywood or a related composite material, so it can definitely wear out over time.
First, old roofing nails should be removed from the roof deck. Then, it should be examined to find warped, softened, or cracked decking material – all of which should be replaced.
Mold in the decking material can suggest a more serious problem with moisture infiltration. Naturally, all molded-out portions of decking should also be removed right away.
3. Replace The Underlayment
A roof’s underlayment is the tough felt layer that sits directly on the roof deck. This functions as a waterproof membrane that protects you from Jacksonville’s most severe weather.
Older roofs probably have asphalt-saturated felt, which was popular until around 2004.
These days, more effective synthetic alternatives are available. Non-bitumen synthetic underlayment is laid in most roof replacements, but some contractors offer high quality rubberized asphalt.
Once these layers have been fully replaced, the roofer should examine roof flashing, vent pipes, and other common structural weak points. Notably, flashing does not always need to be replaced.
Florida building codes are always changing to handle rough weather better. Your roofing team should be fully up to date. For help from Jacksonville’s roof replacement experts, contact Plair Homes today.
