Can I Install a New Roof Over My Old One?
Replacing a roof can be an expensive investment with potentially long-term consequences, and often presents its own set of problems that must be resolved.
Some homeowners choose re-roofing over their old one in an effort to cut costs; however, roofing contractors strongly advise against this as an approach. Here's why.
Costs
Roof replacement can be an important investment for your home. Unfortunately, its costs can quickly add up, leading to many homeowners searching for ways to cut corners when making this important purchase.
One option for saving money when installing a new roof over an old one, known as reroofing, is installing an overlay or "reroofing." While this method may save on removal costs, it may not always be viable since existing shingles must be completely flat and level and most building codes only permit two layers of roofing on one property.
No, repairs won't extend the lifespan of old sections of your roof any further; at best it may only postpone the day when a full replacement becomes necessary. Furthermore, it can be challenging and expensive to work around any specific features on your roof like chimneys or skylights; complete roof replacement is often the superior solution.
Materials
If your roof has been compromised by severe storm damage or simply wear-and-tear over time, its replacement might become necessary. Many individuals question if they can place new shingles over the existing ones but there are certain conditions which must first be fulfilled for that to happen.
One of the key components is that asphalt shingles must always be placed over asphalt shingles – it is impossible to mix different materials, such as wood tiles or slate roofing tiles. Furthermore, curling shingles need to be addressed prior to proceeding with any roof replacement process.
If the substrate of your roof has serious deficiencies, overlaying shingles won't suffice – instead you must tear it all off and rebuild from scratch.
Safety
When installing a new roof over an old one, roofing contractors will first need to remove the old shingles – known as reroofing or roofing over. While this adds time and may cause some damage – protruding nails from old shingles may tear holes into new shingles or tear away at tack strips; additionally, reroofing could add extra weight onto an already sloped roof structure, potentially leading to cracks appearing in walls or foundations of your house as weight is added back ontop.
Curling shingles necessitating roof replacement are an issue. Curls can arise for various reasons and replacing it entirely is often necessary to fix them. Furthermore, experienced roofers know that taking down an old roof allows them to check for problems buried underneath its new layer – including plywood sheathing issues that could potentially prevent new shingles from being placed properly on top.
