Even if a roof is sagging, it need not always be entirely replaced. Most of the time, simply renewing or supporting specific portions of the roof structure is sufficient. Only the roof covering should be changed in the best-case scenario. Read more about roof renovation and the factors a Rubber Roof Contractors NYC considers when assessing the state of a roof here.
What happens if the purlins sag?
The purlins on the roof must not sag. If this is the case, there are two possibilities: wetness in the wood, a big load, or improper construction.
1. Moisture-damaged wood
If moisture or insects (woodworm, termites) eat away at the roof purlins, the only option is to totally replace the roof purlins. Wooden elements that are still in good condition are also safeguarded.
2. Sagging caused by severe loading or poor construction
You should not replace the entire roof if the purlins sag owing to high loading or a soft construction. A roofer can reinforce the structure by adding more beams and boards. After that, the roof is adjusted. The potential of direction is determined by the space beneath the roof. It is not an issue if the room is uninhabited, but if it is a bedroom or study, re-roofing is much more difficult.
When should you replace the foot purlin?
The horizontal beam right beneath the roof is the foot purlin. The weight of the roof is distributed to the walls below by this purlin. Because it is attached to the wall and is exposed to dampness, this beam is difficult to stand. A rotting foot purlin can occasionally be replaced. To accomplish this, a portion of the roof covering and roof boards must be removed.
The purlins are supported and lifted somewhat with the use of supports. The rotten foot purlin is then sawed and removed by Empire contractors. With an overleaf, a new foot purlin is installed against the old one. After that, the foot purlin is fastened to the facade with (chemical) anchors.
Partially renovated: should the roof be replaced or reused?
Most of the time, there is nothing wrong with the roof structure and simply replacing the roof covering is adequate. Roof tiles have a lifespan of about 10 to 15 years and should only be replaced after that. Is there still no under-roof? Consider having it constructed. This not only saves energy but also protects against moisture.
If the roof covering is still in good condition and just the roof framework has been eaten away, you can reuse the roof tiles. Keep in mind, however, that it is frequently more expensive than purchasing new roof tiles. The old roof tiles should be removed and inspected by Roof Repair NYC.
Examine the rainfall drainage as well!
The contractor will assess the roof and the rainfall drainage during a roof inspection. It will need to be renovated or replaced depending on its condition. Leaks are common in old buildings. Sometimes huge sections of the gutter are rotting. The gutter can also be repaired or replaced during a roof replacement, keeping costs to a minimum.
As an alternative, use overlay.
When the roof structure is still sound and only the slates need to be replaced, a roof overlay can be perfectly put to a pitched roof. An overlay can also be put on a roofing or corrugated sheet roof. The work can be completed quickly by Masonry Contractors NYC, but it will alter the appearance of the roof. Roof tiles are generally well-made and come in a variety of styles, but they will never rival the beauty of natural slate. More information on overlaying roofs can be found here.
